Introduction: Vermiform Appendix is a part of caecum and hence a part of large intestine. Normally, it does not present with a true mesentery. However, sometimes a peritoneal fold called mesenteriole or mesentery of the appendix may be present. The characteristic features of large intestine namely the appendices epiploicae is not seen in caecum, appendix and rectum. During our routine cadaveric dissection, we came across a few specimens of appendix with appendices epiploicae.
Aim: To study the mesentery of the appendix and the presence of small Appendices Epiploicae in appendix macroscopically and microscopically.
Materials and Methods: During our routine cadaveric dissection, over a period of 5 years, we observed the appendix of 75 cadavers macroscopically for the presence of mesentery and appendices epiploicae. Simultaneously, during the same period 116 post-appendicectomy specimens that came to pathology department for reporting was studied macroscopically and microscopically for the same. The post-appendicectomy specimens were obtained from our institute Shri Sathya Sai Medical College and Research Institute, Kancheepuram.
Results: Appendices Epiploicae was observed macroscopically in 7 out of 75 cadaveric specimens and only microscopically in 76 out of 116 Appendix specimens removed at surgery.
Conclusion: This less reported finding is presented for its clinical importance, wherein presence of Appendices Epiploicae of Appendix can lead to torsion and inflammation of Appendix and can be considered in the differential diagnosis of acute abdomen.
