Anatomical and clinical variations in the mesoappendix and appendicular arteries: implications for appendicitis and surgical outcomes

Abstract

Background

Anatomical variations in the mesoappendix and appendicular arteries play a crucial role in the development and management of appendicitis. This study aimed to analyze these variations and their clinical implications.

Methods

A retrospective analysis of 287 patients who underwent appendectomy was conducted. Data on mesoappendix extension, appendicular arterial patterns, and appendicitis type were collected. Statistical analyses, including chi-square tests and t-tests, were performed to explore the relationships between variables.

Results

The most common mesoappendix extension was ‘Whole Length’ (51.22%), followed by ‘Two-thirds Length’ (32.06%). A ‘Single Artery’ supplied the appendix in 69.68% of cases, with the ileocolic artery being the primary origin (62.03%). Acute appendicitis is more common in younger patients, whereas chronic appendicitis is prevalent among older individuals. Significant associations were observed between mesoappendix extension and arterial origin (P < 0.001) as well as between age and appendicitis type (P = 0.034).

Conclusion

This study highlights the anatomical and clinical variabilities of the mesoappendix and appendicular arteries. Understanding these variations is essential to optimize surgical outcomes and minimize complications. Future research should explore the implications of these findings in diverse populations.
