Study of anatomical variations of appendix in appendectomy patients at Wad Medani Teaching Hospital, Gezira- Sudan

Background The appendix, a true diverticulum arising from the posteromedial cecal border. The base of the appendix can be reliably located at the tip of the cecum. The length of the appendix varies and it can be placed in different positions. Anatomical variations in the location of appendix can prove challenging for surgeons.
Aim: To study the anatomical variations of the appendix in patients underwent appendectomy
Methods: This cross-sectional study was conducted at the surgical department in Wad Medani teaching hospital during the year 2023 involving 50 appendectomy patients, the collected information was entered into SPSS software (Version. 23) and analyzed.
Results: Twenty-nine (58%) out of 50 patients were females, while 21were males (42%). 58% of patients were between 18-30years. The retrocecal position of the appendix’s head was the commonest anatomical position (68%). The mean length of the appendix was 70 mm. Mesoappendix was complete in 74% of the patients and the posterior position was the most common position (78%). Significant association was found between sex and length of appendix p=0.02 but not between sex and the position of the appendix head p=0.46.
Conclusion: The study concluded that, a high frequency of retro-cecal position was observed and posterior position was the most common appendix orientation, whereas most of the patients have had a complete mesoappendix.
