Extent of Mesoappendix of Vermiform Appendix in Bangladeshi People.

Background: The mesentery of the appendix extends almost to the appendicular tip along the whole tube or may not be to the tip. The mesoappendix has a free border which carries the blood supply to the organ. Failure of the mesoappendix to reach the tip probably reduces the vascularization of the tip of the organ making it more liable to become gangrenous and hence early perforation occurs during inflammation. Objective: This cross sectional study was carried out to advance our knowledge regarding the extent of mesoappendix in Bangladeshi people and also to find out the variations in the anatomical positions of the vermiform appendix in Bangladeshi population and their distribution according to the sex. Methods: A total of 100 (60 male and 40 female) specimens of vermiform appendix were collected of different age and sex during postmortem examination in the morgue of Mymensingh Medical College from July 2006 to June 2007. Data was collected by convenient sampling technique. Results: In this study pelvic position of the vermiform appendix were common in both sexes. The two thirds extension of mesoappendix was found in 45% cases where as in pelvic position it was 26 (14 male and 12 female) cases. Half and whole extension of mesoappendix were found in 31% and 24% cases respectively. Among half extension of mesoappendix, retrocaecal position were found to be more (12) than other positions. In whole extension of vermiform appendix pelvic position were found to be common (16) than others. Conclusion: This study provides certain basic information of extent of mesoappendix of vermiform appendix of Bangladeshi population which is responsible for vascularization of the organ and severity during inflammation.

Mass of the Vermiform Appendix in Bangladeshi People.

This study was done to measure the weight of vermiform appendix in Bangladeshi people to augment the data regarding variational anatomy in our setting. A total 100 vermiform appendix (male – 60, female – 40) were excised from cadaver of different age and sex during routine post mortem examination in the autopsy laboratory of Forensic Medicine Department of Mymensingh Medical College. This cross-sectional study was done by convenient sampling technique. The weight depended on length and thickness. The weight decreases gradually with advancing age probably decreasing number of lymphatic follicle and that replaced by connective tissue. Lymphatic follicles were examined and estimated by microscope. For convenience of differentiating the weight of vermiform appendix in relation to age and sex, specimens were categorized in four age groups (up to 20 year, 21 – 35 years, 36 – 55 years, 56 – 70 years). Mean weight of vermiform appendix was maximum in group – B (4.07 ± SE 0.82 gm) and minimum in group D (3.01 ± SE 0.74 gm). The weight range was from 2 gm (group – D) to 5.50 gm (group – B). Diameter of lymphatic follicle was largest 43.08 micrometer in group-A, and least diameter was 3.08 micrometer in group – D. The range of number of lymphatic follicle was 1 to 6. Mean number of lymphatic follicle in male was 4.48 & in female were 5.40.

Histomorphological study of lymphoid follicle of vermiform appendix.

The study was done to find out the number of lymphoid follicle of vermiform appendix in Bangladeshi people and to increase the knowledge regarding variational anatomy in our population. Total 40 fresh appendixes were collected for histological study of different age and sex during postmortem examination in the autopsy laboratory of Forensic department of Mymensingh Medical College. This cross sectional descriptive study was done by convenient sampling technique. For convenience of differentiating the number of lymphoid follicle of vermiform appendix in relation to age and sex, findings were classified in four groups, up to 20 years, 21 to 35 years, 36 to 55 years and 56 to 70 years. In the present study the number of lymphoid follicle were highest in group A, mean were (5.40+/-1.30) and lowest in group D where mean were (1.05+/-0.35). In male mean were 3.16 and in female mean were 2.86. Diameter of the lymphoid follicle in group A was highest (40.14+/-2.66) and lowest in group D (0.24+/-1.35). Number of germinal centre are highest in group B (2.20 +/- 0.45) and lowest in group D (0.00 +/- 0.00).
