Objective: The objective of this study was to find out the morphological and histological study on post mortem vermiform appendix of adult population in Bangladesh. Materials and method: In the present descriptive type of cross sectional study, 60 normal vermiform appendix of both sex were observed in dead bodies during routine postmortem examination due to accidental and unnatural (unclaimed) death. Length and diameter were measured with a Digital sliding (measuring types) Vernier caliper. Three pieces were taken one close to the tip, one from the middle and one from the base and were processed and examined under light microscope. The number of mucosal glands and germinal centers of lymphoid follicles present in the slide were counted. Data were processed and analyzed. Results: length of the vermiform appendix decreases gradually with increasing age and was highly significant (p < 0.001) in the present study. Statistically highly significant negative correlation between age of the cadavers(subjects)and wall thickness and diameter of the vermiform appendix (r= -0.84, p < 0.001) was found. The diameter in children is wide and the lumen is almost obliterated in the elderly. There was no statistically significant difference of length, wall thickness & diameter of the vermiform appendix between the male and female (p > 0.05).

Conclusions: Morphological and histological study of vermiform appendix might be used to gather knowledge about the changes of appendicular features in different age groups of Bangladeshi population and would also be helpful for the anatomists, anthropologists, forensic experts, pathologists and surgeons. Further studies with a larger sample size are required for better decision.
