"Journal of Clinical and Diagnostic Research is at present a well-known Indian originated scientific journal which started with a humble beginning. I have been associated with this journal since many years. I appreciate the Editor, Dr. Hemant Jain, for his constant effort in bringing up this journal to the present status right from the scratch. The journal is multidisciplinary. It encourages in publishing the scientific articles from postgraduates and also the beginners who start their career. At the same time the journal also caters for the high quality articles from specialty and super-specialty researchers. Hence it provides a platform for the scientist and researchers to publish. The other aspect of it is, the readers get the information regarding the most recent developments in science which can be used for teaching, research, treating patients and to some extent take preventive measures against certain diseases. The journal is contributing immensely to the society at national and international level."

" Journal of Clinical and Diagnostic Research (JCDR) is a multi-specialty medical and dental journal publishing high quality research articles in almost all branches of medicine. The quality of printing of figures and tables is excellent and comparable to any International journal. An added advantage is nominal publication charges and monthly issue of the journal and more chances of an article being accepted for publication. Moreover being a multi-specialty journal an article concerning a particular specialty has a wider reach of readers of other related specialties also. As an author and reviewer for several years I find this Journal most suitable and highly recommend this Journal."

Dr. Mamta Gupta,
"It gives me great pleasure to be associated with JCDR, since last 2-3 years. Since then I have authored, co-authored and reviewed about 25 articles in JCDR. I thank JCDR for giving me an opportunity to improve my own skills as an author and a reviewer.
It 's a multispecialty journal, publishing high quality articles. It gives a platform to the authors to publish their research work which can be available for everyone across the globe to read. The best thing about JCDR is that the full articles of all medical specialties are available as pdf/html for reading free of cost or without institutional subscription, which is not there for other journals. For those who have problem in writing manuscript or do statistical work, JCDR comes for their rescue.
The journal has a monthly publication and the articles are published quite fast. In time compared to other journals. The on-line first publication is also a great advantage and facility to review one's own articles before going to print. The response to any query and permission if required, is quite fast; this is quite commendable. I have a very good experience about seeking quick permission for quoting a photograph (Fig.) from a JCDR article for my chapter authored in an E book. I never thought it would be so easy. No hassles.
Reviewing articles is no less a pain staking process and requires in depth perception, knowledge about the topic for review. It requires time and concentration, yet I enjoy doing it. The JCDR website especially for the reviewers is quite user friendly. My suggestions for improving the journal is, more strict review process, so that only high quality articles are published. I find a a good number of articles in Obst. Gynae, hence, a new journal for this specialty titled JCDR-OG can be started. May be a bimonthly or quarterly publication to begin with. Only selected articles should find a place in it.
An yearly reward for the best article authored can also incentivize the authors. Though the process of finding the best article will be not be very easy. I do not know how reviewing process can be improved. If an article is being reviewed by two reviewers, then opinion of one can be communicated to the other or the final opinion of the editor can be communicated to the reviewer if requested for. This will help one’s reviewing skills.
My best wishes to Dr. Hemant Jain and all the editorial staff of JCDR for their untiring efforts to bring out this journal. I strongly recommend medical fraternity to publish their valuable research work in this esteemed journal, JCDR".

"I wish to thank Dr. Hemant Jain, Editor-in-Chief Journal of Clinical and Diagnostic Research (JCDR), for asking me to write up few words.
Writing is the representation of language in a textual medium i e; into the words and sentences on paper. Quality medical manuscript writing in particular, demands not only a high-quality research, but also requires accurate and concise communication of findings and conclusions, with adherence to particular journal guidelines. In medical field whether working in teaching, private, or in corporate institution, everyone wants to excel in his / her own field and get recognised by making manuscripts publication.


Authors are the souls of any journal, and deserve much respect. To publish a journal manuscripts are needed from authors. Authors have a great responsibility for producing facts of their work in terms of number and results truthfully and an individual honesty is expected from authors in this regards. Both ways its true "No authors-No manuscripts-No journals" and "No journals–No manuscripts–No authors". Reviewing a manuscript is also a very responsible and important task of any peer-reviewed journal and to be taken seriously. It needs knowledge on the subject, sincerity, honesty and determination. Although the process of reviewing a manuscript is a time consuming task butit is expected to give one's best remarks within the time frame of the journal.
Salient features of the JCDR: It is a biomedical, multidisciplinary (including all medical and dental specialities), e-journal, with wide scope and extensive author support. At the same time, a free text of manuscript is available in HTML and PDF format. There is fast growing authorship and readership with JCDR as this can be judged by the number of articles published in it i e; in Feb 2007 of its first issue, it contained 5 articles only, and now in its recent volume published in April 2011, it contained 67 manuscripts. This e-journal is fulfilling the commitments and objectives sincerely, (as stated by Editor-in-chief in his preface to first edition) i e; to encourage physicians through the internet, especially from the developing countries who witness a spectrum of disease and acquire a wealth of knowledge to publish their experiences to benefit the medical community in patients care. I also feel that many of us have work of substance, newer ideas, adequate clinical materials but poor in medical writing and hesitation to submit the work and need help. JCDR provides authors help in this regards.
Timely publication of journal: Publication of manuscripts and bringing out the issue in time is one of the positive aspects of JCDR and is possible with strong support team in terms of peer reviewers, proof reading, language check, computer operators, etc. This is one of the great reasons for authors to submit their work with JCDR. Another best part of JCDR is "Online first Publications" facilities available for the authors. This facility not only provides the prompt publications of the manuscripts but at the same time also early availability of the manuscripts for the readers.
Indexation and online availability: Indexation transforms the journal in some sense from its local ownership to the worldwide professional community and to the public.JCDR is indexed with Embase & EMbiology, Google Scholar, Index Copernicus, Chemical Abstracts Service, Journal seek Database, Indian Science Abstracts, to name few of them. Manuscriptspublished in JCDR are available on major search engines ie; google, yahoo, msn.
In the era of fast growing newer technologies, and in computer and internet friendly environment the manuscripts preparation, submission, review, revision, etc and all can be done and checked with a click from all corer of the world, at any time. Of course there is always a scope for improvement in every field and none is perfect. To progress, one needs to identify the areas of one's weakness and to strengthen them.
It is well said that "happy beginning is half done" and it fits perfectly with JCDR. It has grown considerably and I feel it has already grown up from its infancy to adolescence, achieving the status of standard online e-journal form Indian continent since its inception in Feb 2007. This had been made possible due to the efforts and the hard work put in it. The way the JCDR is improving with every new volume, with good quality original manuscripts, makes it a quality journal for readers. I must thank and congratulate Dr Hemant Jain, Editor-in-Chief JCDR and his team for their sincere efforts, dedication, and determination for making JCDR a fast growing journal.
Every one of us: authors, reviewers, editors, and publisher are responsible for enhancing the stature of the journal. I wish for a great success for JCDR."

Dr. Shankar P.R.

"On looking back through my Gmail archives after being requested by the journal to write a short editorial about my experiences of publishing with the Journal of Clinical and Diagnostic Research (JCDR), I came across an e-mail from Dr. Hemant Jain, Editor, in March 2007, which introduced the new electronic journal. The main features of the journal which were outlined in the e-mail were extensive author support, cash rewards, the peer review process, and other salient features of the journal.
Over a span of over four years, we (I and my colleagues) have published around 25 articles in the journal. In this editorial, I plan to briefly discuss my experiences of publishing with JCDR and the strengths of the journal and to finally address the areas for improvement.
My experiences of publishing with JCDR: Overall, my experiences of publishing withJCDR have been positive. The best point about the journal is that it responds to queries from the author. This may seem to be simple and not too much to ask for, but unfortunately, many journals in the subcontinent and from many developing countries do not respond or they respond with a long delay to the queries from the authors 1. The reasons could be many, including lack of optimal secretarial and other support. Another problem with many journals is the slowness of the review process. Editorial processing and peer review can take anywhere between a year to two years with some journals. Also, some journals do not keep the contributors informed about the progress of the review process. Due to the long review process, the articles can lose their relevance and topicality. A major benefit with JCDR is the timeliness and promptness of its response. In Dr Jain's e-mail which was sent to me in 2007, before the introduction of the Pre-publishing system, he had stated that he had received my submission and that he would get back to me within seven days and he did!
Most of the manuscripts are published within 3 to 4 months of their submission if they are found to be suitable after the review process. JCDR is published bimonthly and the accepted articles were usually published in the next issue. Recently, due to the increased volume of the submissions, the review process has become slower and it ?? Section can take from 4 to 6 months for the articles to be reviewed. The journal has an extensive author support system and it has recently introduced a paid expedited review process. The journal also mentions the average time for processing the manuscript under different submission systems - regular submission and expedited review.
Strengths of the journal: The journal has an online first facility in which the accepted manuscripts may be published on the website before being included in a regular issue of the journal. This cuts down the time between their acceptance and the publication. The journal is indexed in many databases, though not in PubMed. The editorial board should now take steps to index the journal in PubMed. The journal has a system of notifying readers through e-mail when a new issue is released. Also, the articles are available in both the HTML and the PDF formats. I especially like the new and colorful page format of the journal. Also, the access statistics of the articles are available. The prepublication and the manuscript tracking system are also helpful for the authors.
Areas for improvement: In certain cases, I felt that the peer review process of the manuscripts was not up to international standards and that it should be strengthened. Also, the number of manuscripts in an issue is high and it may be difficult for readers to go through all of them. The journal can consider tightening of the peer review process and increasing the quality standards for the acceptance of the manuscripts. I faced occasional problems with the online manuscript submission (Pre-publishing) system, which have to be addressed.
Overall, the publishing process with JCDR has been smooth, quick and relatively hassle free and I can recommend other authors to consider the journal as an outlet for their work."

Abstract

Introduction: The overall incidence of cholecystitis in children appears to be increasing although the exact frequency of acute and chronic cholecystitis among children in India or worldwide remains unknown. The frequency of paediatric cholecystitis has proportionally increased with the childhood obesity and intake of habitual fatty food.

Aim: To present the histopathological concordance of Laparoscopic Cholecystectomy (LC) performed among children for a clinical diagnosis of Gallbladder (GB) disease.

Materials and Methods: A single centre retrospective study was performed including histopathological and relevant clinical data of all paediatric LC performed at Career Institute of Medical Sciences and Hospital, Lucknow, Uttar Pradesh, India, between January 2019 to January 2022. Paediatric patients who had undergone LC in the designated time period for a clinical diagnosis of cholelithiasis and/or inflammatory GB disease with classical signs of inflammation were included. Study population with LC procedure submitted for histological evaluation were identified by performing an electronic search through the archives of Department of Pathology, Career Institute of Medical Sciences and Hospital, Lucknow, Uttar Pradesh, India, followed by a manual review of GB specimens, histopathology slides and reports.

Results: Among 265 patients who underwent LC during this period, there were 62 (23.4%) children. The average age of presentation was 13 years (range 5-18 years), 49 (79%) were girls and 13 (21%) were boys. The clinical diagnosis for which paediatric LCs were performed were cholelithiasis among 51% and cholecystitis among 48%. On histopathological concordance these turned out to be chronic cholecystitis among 98.4% children among which 51% were associated with cholelithiasis. Calculous cholecystitis was more frequent than acalculous cholecystitis. Chronic cholecystitis with cholelithiasis and cholesterolosis was more frequent among adolescent girls.

Conclusion: This study suggests that chronic cholecystitis accounts for the majority of inflammatory diseases among children undergoing LC for a GB disease and may or may not be associated with cholelithiasis. Chronic cholecystitis with cholelithiasis and cholesterolosis seem more frequent among adolescent girls.

The spectrum of GB disorders in the paediatric population has changed over the past three decades (1). Cholecystitis is defined as inflammation of the GB traditionally divided into acute and chronic subtypes. These subtypes are considered to be separate entities but are closely related in the paediatric age group. Both acute and chronic cholecystitis may also be considered calculous or acalculous, but the inflammatory process remains the same. Most LCs performed for acute cholecystitis show evidence of chronic inflammation, supporting the concept that acute cholecystitis may actually be an exacerbation of chronic distension and GB tissue damage. Although both acute and chronic cholecystitis can be related to cholelithiasis, however in childhood acalculous cholecystitis may be the most frequent form (2). The exact frequency of acute and chronic cholecystitis among children in India or United State remains unknown (2). The prevalence of chronic cholecystitis in paediatric age group ranges from 0.13-1.9% including both calculous and acalculous forms (3). Recent epidemiological studies and case reports have suggested an increase in acalculous form of chronic cholecystitis in the paediatric population (4). While cholecystitis was previously attributable mainly to haemolytic disease, the frequency of paediatric cholecystitis due to cholelithiasis has proportionally increased with the childhood obesity epidemic suggesting a strong correlation (5). There however, seems to be more than one factor of concern at play which may include rapid change to urban style feeding habits and fatty food intolerance. As LC is the standard of care for cholecystitis in children, it is also resulting in increased number of LCs performed in paediatric age group (6),(7). Despite the increased frequency of chronic cholecystitis in children and adolescents there is paucity of literature in this regard which results in under estimation of the burden. Most paediatric studies focus on cholelithiasis and biliary dyskinesia rather than inflammatory GB disease (8).

The aim of this study was to present the clinicopathological concordance of LCs performed among children at a single centre.

Material and Methods

This was a single centre retrospective study performed on GB specimens, at Career Institute of Medical Sciences and Hospital, Lucknow, Uttar Pradesh, India, between January 2019 to January 2022. Analysis of data was done from January 2022 to June 2022. The study was approved by the Institutional Ethics Committee (IEC) for Scientific Research vide reference number CIMSH-IEC-R 25/2018.

Inclusion criteria: Initially all patient who had undergone LC in the designated time period for a clinical diagnosis of cholelithiasis and/or inflammatory GB disease with classical signs of inflammation were included. Thereafter the target paediatric age group of 0-18 years according to Indian Association of Paediatricians were identified for further study (9). Inclusive symptoms considered indicative of inflammation were right upper quadrant abdominal pain radiating to mid back or right scapula, fever, nausea, vomiting and abdominal discomfort related to intake of fatty food. Inclusive clinical and laboratory parameters considered to be consistent with GB disease included positive Murphy’s sign, elevated white blood cell count, elevated C-reactive Protein (CRP) and radiological evidence of the clinical diagnosis on ultrasound (US), Computerised Tomography (CT), or Hepatobiliary Iminodiacetic Acid scan (HIDA).

Exclusion criteria: Paediatric LC performed in children as part of other complicated procedures such as those for GB polyps, biliary atresia or resection of choledochal cyst were excluded from the study.

Study Procedure

Study population with LC procedure submitted for histological evaluation were identified by performing an electronic search through the archives, followed by a manual review of GB specimens, histopathology slides and reports independently to resolve any discrepancy. Relevant clinical data was collected using appropriate International Classification Of Diseases (ICD 10) for medical diagnosis (10). Entire data was rechecked manually to delete duplications, processed and analysed in Microsoft excel format. Concordance of clinical diagnosis and histopathological diagnosis was examined case by case.

The paediatric LC specimens for histopathological examinations were fixed in 10% neutral buffered formalin, embedded in paraffin wax and cut into 5 mm sections. Three sections were taken from each specimen one each from cystic duct, body and fundus of GB. Tissue sections were stained with Haematoxylin and Eosin (H&E). The histopathological evaluation was done based on the following defined criteria. Histopathological diagnosis of acute cholecystitis was made if the GB was grossly enlarged, oedematous with turbid bile and serosal exudate. These gross features were validated against the histological evidence of transmural oedema, neutrophilic infiltration and haemorrhage, serosal fibrin with subserosal haemorrhage and mucosal ulceration. A diagnosis of chronic cholecystitis was made if GB grossly showed evidence of chronic inflammation such as serosal adhesions or sub serosal fibrosis and a wall thickening of more than 3 mm. These gross features were validated against the histological evidence of increased mononuclear inflammatory infiltrate in lamina propria extending into muscularis propria and pericholecystic tissue, hypertrophy of muscularis propria, accentuation of Rokitansky Aschoff sinuses and mural fibrosis. Cholesterolosis was diagnosed when mucosal surface of the specimen grossly showed fatty streaks and lamina propria showed lipid laden foamy histiocytes histopathologically (11).

Statistical Analysis

Data was entered and analysed using commercial software Statistical Package for Social Science (IBM SPSS Statistics, version 23.0. Armonk, NY: IBM Corp).The Mann-Whitney U-test was used for comparison of variables. Categorical variables were compared by the Chi-square test, presented as counts and percentages, and a p-value <0.05 was considered significant.

Results

Among total of 265 patients who underwent LC during this period there were 62 (23.4%) children who underwent LC for cholelithiasis and/or inflammatory GB disease. The average paediatric age of presentation was 13 years (range 5-18 years) with highest frequency among girls (Table/Fig 1). All patients studied presented with complaints of abdominal pain. Ten children (16.1%) clinically presented with acute symptoms with an average duration of pain for two days. Twenty children (32.3%) presented with chronic symptoms with an average duration of pain for six months. The clinical presentation among rest of the 32 (51.6%) was variable with nausea, vomiting and abdominal discomfort related to intake of fatty food. One patient of acute cholecystitis who presented clinically with high grade fever, raised CRP and leukocytosis had received antimicrobial treatment and none of the patients with clinical diagnosis of cholecystitis or cholelithiasis had received preoperative antimicrobial drugs. Among 56 children (90.3%) who had preoperative US suggestive of cholelithiasis all turned out to be associated with chronic cholecystitis and among five children (8.1%) who underwent preoperative CT suggestive of cholecystitis all turned out to be chronic cholecystitis on histopathological examination. One child (1.6%) who underwent preoperative US and HIDA suggestive of acute cholecystitis with cholelithiasis turned out to be the same on histopathological examination (Table/Fig 2). On gross examination there was no significant variation in size and volume of GB within the studied paediatric age group. Overall 61 (98.4%) cases turned out to be chronic cholecystitis and 1 (1.6%) turned out to be acute cholecystitis on histopathological examination. Among 10 (16.1%) cases with a clinical diagnosis of acute cholecystitis, only one case turned out to be acute calculous cholecystitis while remaining nine were chronic cholecystitis on histopathological examination. The clinical diagnosis of cholelithiasis among 32 (51.6%) and cholecystitis among 30 (48%) turned out to be chronic cholecystitis among 98.4% on histopathological concordance, among which 51% were associated with cholelithiasis and 22 (69%) were accompanied with cholestrolosis [Tables/Fig-3]. Chronic cholecystitis with cholelithiasis and cholesterolosis was more frequent in girls (79%). One out of 10 (16%) patients clinically presenting with acute cholecystitis, 14 out of 20 (70%) clinically presenting with chronic cholecystitis and 30 out of 32 (94%) presenting with cholelithiasis were associated with cholesterol stones. The remaining in each category were pigment stones. Representative ultrasound, gross and microscopy are presented in (Table/Fig 4),(Table/Fig 5), respectively.

Discussion

This study shows that LCs performed for paediatric cholecystitis to be a much more prevalent disease than previously described. Overall 61 (98.4%) cases turned out to be cholecystitis and 1 (1.6%) turned out to be acute cholecystitis on histopathological examination. Among 10 (16.1%) cases with a clinical diagnosis of acute cholecystitis only one case turned out to be acute calculous cholecystitis while remaining nine were cholecystitis on histopathological examination. Other clinical diagnosis were; 32% of children presented with chronic cholecystitis, 16% with acute onset of symptoms and 51% with cholelithiasis. These findings were consistent with those reported by Blackwood PB and Grabowski J (8). The study result also demonstrates that the majority of the children have chronic cholecystitis regardless of their clinical presentation. The average paediatric age of presentation was 13 years (range 5-18 years) with highest frequency among girls.

In adolescence, differences in the frequency of cholecystitis based on race, genetics, and gender are becoming more evident as was also noted from this study that adolescent Indian girls seem much more at risk of developing the disease than boys. Gowda DJ et al., reported an average age of 9.4 years for Indian children undergoing LC for GB disease while in the present study it was 13 years. This could be partly explained by the rapid change in life style and feeding habits since the previous study exacerbated by easy access and delivery of fatty food through food applications (12). Among 6040 paediatric cholecystectomy performed between 1993-2012 Murphy PB et al., reported mean age as 14.3 years with 79.6% of children being girls. The crude incidence per 100,000 person-years increased from 8.8-13.0 (p<0.001) from 1993 96–2009–12, respectively. The gender-specific incidence showed a larger increase among girls from 14.7-21.1 per 100,000 children-years (p<0.001) (13). Walker SK et al., also reported an increase in the incidence of paediatric cholecystitis from 1997-2009, but the study does not specify the subtypes of cholecystitis or age and gender related distribution. They also found that 53% of the children were either obese or overweight (14). Obesity and Hispanic ethnicity are strongly correlated with symptomatic paediatric gallbladder disease (15). It is becoming evident that the overall incidence of paediatric cholecystitis appears to have increased in the last three decades and with this increasing incidence, it is imperative that we understand the underlying pathophysiology in order to better treat these children. High consumption of fatty foods by young children may be the leading cause. In children with chronic haemolysis (eg, haemolytic anemias) the incidence of cholecystitis is much higher than in the general population. Biliary sludge and/or cholelithiasis are implicated among 1 in 5 children with haemolytic anemia before their adolescent years. Obesity alone accounts for some 8-33% of cholelithiasis observed in children (16). The changing demographic of cholecystitis among paediatric age group is a neglected aspect of the obesity epidemic. Other than a high caloric intake that leads to obesity, any importance of the dietary content is unclear and difficult to analyse in context of paediatric cholecystitis. Diets specifically high in cholesterol, fatty acids, carbohydrates or legumes seem to increase the risk of cholelithiasis and may therefore be implicated in causing calculous cholecystitis indirectly. In contrast, unsaturated fats, coffee, fibre, ascorbic acid (vitamin C), and calcium reduce the risk (17). Certainly, the shift to a more Western diet, high in refined carbohydrates and unsaturated fats and low in fibre, best explains the profound increase in cholestrolosis and cholesterol stones amongst American Indians (unmasking their presumed genetic burden) and in European countries. This dietary change also might account for the shift from pigment to cholesterol stones in Asian countries (17).

Although paediatric patients may initially appear with acute cholecystitis, cholelithiasis symptoms frequently precede those of cholecystitis. Biliary colic is caused by cholelithiasis. Patients may report right upper quadrant intermittent abdominal discomfort of varying intensity that may radiate to the scapular region of the back, or pain may be generalised or restricted to the epigastrium. Regarding chronic cholecystitis patients usually present with biliary colic, with an intermittent and indolent history of pain and positive Murphy’s sign. Therefore, differentiation must be made on the basis of findings from the physical examination and diagnostic test (2). Most of the patients in present study presented with nausea, vomiting and pain in the right upper abdomen radiating to scapula. Only one patient presented with fever that turned out to be acute cholecystitis on histopathological examination. Pelizzo G et al., observed severe damage of the GB in their study groups, including signs of chronic inflammation suggesting that children may have milder episodes of self-limited GB inflammation compared with adults, which may lead to delayed surgical intervention and morbidity (18). Cholelithiasis and chronic cholecystitis are independent risk factors for carcinoma of the GB and are therefore reasons for intervening earlier on symptomatic children (19). Interestingly the present study also identified a discrepancy in the preoperative US diagnostic work-up of children for inflammatory GB disease. In the present study 90% of children underwent a preoperative US out of which 51% were diagnosed radiologically as cholelithiasis without specifying acute or chronic inflammation. These turned out to be associated with chronic cholecystitis on histopathological examination. The lower sensitivity of preoperative US for picking up GB inflammation further masks and complicates the rising number of paediatric cholecystitis. A recent study found that US findings have sensitivities as low as 6% for cholecystitis in the paediatric population compared to the adult population where sensitivities are as high as 96% (20). Consistent with the histopathological findings in the present study demonstrating chronic cholecystitis among 98.4% and acute CC among 1.6% children, Tsai J et al., reported 83% children with histopathologic diagnosis of chronic CC and 8% as acute cholecystitis. The slight increase in the present study can be explained by the variation in dietary habits, life style and patient phenotype. As suggested by Tsai J et al., these findings indicate that children undergo multiple episodes of inflammation that are not significant enough to be seen radiologically, yet still produce enough pain that these children present to the hospital for evaluation. As a result of this more indolent course, physicians may be delaying appropriate surgical intervention. This in turn may be increasing paediatric emergency department and primary care visits, adding to the overall healthcare costs (20).

Cholecystitis likely results from prolonged or recurrent episodes of acute inflammation and though most often found in the context of cholelithiasis, it can also be present in absence of cholelithiasis. The understanding of cholelithiasis has progressed significantly since the characterisation of the most likely candidates as being fair, fat, fertile, 40-year-old females. Although cholelithiasis in children is a rare disease with a prevalence between 0.13-0.22% (21). The current trend indicates that it is primarily a disease of adolescent girls, which may partly be related to increase in estrogen levels. In the present study too, it was observed that chronic cholecystitis with cholelithiasis and cholesterolosis was more frequent in girls (69%). Gokce S et al., reported that the most common complications of cholelithiasis are cholecystitis, choledocholithiasis, and pancreatitis (22). In the current study too, 51% of the children had cholecystitis in presence of cholelithiasis. Lee YJ et al., reported 16.9% of cholelithiasis in their study to be associated with cholecystitis. This variation could be partly explained by the differences in the phenotypes of study populations. Conditions such as metabolic disorders, parenteral nutrition, cystic fibrosis, haemolytic diseases and malignancies are strongly correlated with paediatric gallstones (23),(24),(25),(26). On the contrary Enayet A et al., reported the possible aetiology for cholelithiasis among Egyptian children as largely idiopathic (28.6%) followed by G6PD deficiency (14.3%) and hyperlipidaemia (11.4%) (27). Cholelithiasis is also detected more frequently than in previous years because of the increased use of US (28).

Paediatric acute acalculous cholecystitis is estimated to represent 50% of all cases of acute cholecystitis in this population which may be stimulated by a recent viral illness or may be associated with multiple injuries, burns GB ischaemia, sepsis, dehydration or chronic diseases (29). Acute calculous cholecystitis may result from biliary obstruction or impaction of gall stones at GB neck with superadded bacterial infections such as Brucella spp., C. jejuni, C. burnetii, Leptospira spp., Mycobacterium spp., Salmonella spp., and V. cholerae, yeasts (Candida spp.), viruses (HAV, HBV, EBV, CMV, and Flavivirus), and parasites (Plasmodium spp., A. lumbricoides, and Echinococcus spp.). Chronic acalculous cholecystitis is related to chronic biliary sludge post habitual consumption of fatty food and fatty food intolerance (8),(12). The aetiology and predisposing factors of cholecystitis and cholelithiasis in children are interrelated and may ultimately have an influence on interdisciplinary therapeutic decisions and management.

The incidence of paediatric LCs has risen. According to a UK study, the frequency ranges between 0.78 and 2.7/100,000 in children under 16 years (12). The most frequent indication for cholecystectomy in paediatric age group remains radiological evidence of cholecystitis and or cholelithiasis. Pelizzo G et al., reported that both elective and urgent LC are safe and feasible in children. The clinical parameters and US criteria currently used in adults to define the timing of LC do not allow the severity prediction of the GB histopathological condition and consequently the surgical outcome in children (18).

The 2007 Tokyo Guidelines grade the severity of acute cholecystitis to help guide its treatment into mild, moderate, and severe as follows: Mild (grade I); defined as acute cholecystitis with limited GB disease and no dysfunction, making LC a low-risk procedure, Moderate (grade II): defined as acute cholecystitis with extensive GB disease, raised WBC count, palpable, tender mass in upper right quadrant and duration of symptoms longer than 72 hours and Severe (Grade III): defined as acute cholecystitis with multiple organ dysfunction such as, cardiovascular dysfunction, neurological, respiratory, renal, 1 hepatic and haematologic dysfunction (30). Various stages of cholecystitis have been described. Stage 1 (oedematous), corresponding to 2-4 days when GB tissue is intact with oedema in subserosal layer and dilated capillaries and lymphatics. Stage 2 (necrotising), corresponding to 3-5 days, when extensive oedematous and haemorrhage cause necrosis due to compromised blood flow. Stage 3 (suppurative), corresponding to 7-10 days when there is active inflammation with necrosis and suppuration in wall along with fibrous thickening and formation of intramural abscesses. Stage 4 (chronic) resulting from repeated episodes of cholecystitis and characterised by mucosal atrophy, wall fibrosis, neutrophil/lymphocyte/plasma cell infiltration (31).

To the best of author’s knowledge, there are no studies presenting the clinicopathological concordance for paediatric LC from India which highlights the strength of this study. Some of the other strengths of this study include the robust design and transparency.

Limitation(s)

This study has certain limitations and results should be interpreted accordingly. The main one being that it was a retrospective study with a relatively small size of study population over a short period of time which in turn limits the application value of these results. Also this being a single institution study the criteria used in the assessment of cholecystitis, clinically, radiologically and on histopathology may vary with other institutions. Institutional preoperative imaging sensitivity may also vary slightly based on the expertise of those performing and interpreting the imaging studies. Representing the diverse patient spectrum in children with cholecystitis, the case mix and the variety of complications additionally limit the possibility to draw strong conclusions because of even smaller case numbers within subgroup analyses. Therefore, a larger cohort of children is mandatory to study possible associations. Variability in the upper age limit for children in different countries may also be perceived as selection bias.

Conclusion

Chronic cholecystitis accounts for the majority of inflammatory diseases among children undergoing LC for a clinical presentation of GB disease regardless of association with cholelithiasis. The study also reflects a demographic change in the frequency of cholecystitis noticed among Indian children which needs to be highlighted to maintain clinical awareness. Underrated GB inflammation may delay surgical intervention, increase paediatric emergency inflow and lead to complicated surgeries. In view of the fact that greater tissue damage is caused by increased inflammatory response, it is important to consider early intervention among children presenting with symptoms of cholecystitis.
