Study of the Mesoappendix in Bangladeshi People of Different Age and Sex.

The mesoappendix, a fold of peritoneum that suspends the vermiform appendix from the mesentery of the terminal ileum, serves as the channel for its essential blood supply. In this study, specimens including the vermiform appendix and adjacent structures such as the distal ileum, cecum and the proximal portion of the ascending colon were collected from Bangladeshi cadavers aged between 5 and 75 years. The samples were obtained from medico-legal autopsy cases conducted in the Department of Forensic Medicine, Mymensingh Medical College (MMC), Mymensingh, Bangladesh, between October 2016 and March 2017. The collected specimens were categorized into four age groups: Group A (up to 20 years), Group B (21-40 years), Group C (41-60 years) and Group D (above 60 years). Each group was further subdivided by sex. Observations were made to determine whether the mesoappendix extended to the tip of the appendix or not. The length of the mesoappendix was measured along its attached border to the vermiform appendix using a thread, which was then placed on a measuring scale and expressed in centimeters. The breadth was measured at the midpoint of the appendix- from the attached border to the free border- using a point divider and the measurement was recorded in centimeters. In this study, the mesoappendix extended to the tip in 46 cases (65.7%) and did not reach the tip in 24 cases (34.3%). The extension up to the tip was found in 72.4% of Group A, 53.1% of Group B, 76.9% of Group C and 81.9% of Group D. Conversely, it did not extend to the tip in 28.6%, 46.9%, 23.1% and 18.1% of these respective groups. The mean lengths of the mesoappendix were 8.35±1.66?cm, 7.47±1.81?cm, 7.19±1.72?cm and 6.25±1.31?cm in Group A, B, C and D, respectively, showing a gradual decrease with advancing age. Similarly, the mean breadths were 1.67±0.47?cm, 1.58±0.36?cm, 1.52±0.38?cm and 1.41±0.43?cm, with the maximum mean breadth observed in Group A and the minimum in Group D. This study aimed to provide a comprehensive analysis of mesoappendix extension, length and breadth. By integrating anatomical, pathological and clinical perspectives, we hope to contribute valuable insights to the existing literature and provide a foundation for improved surgical decision-making and patient care.
