Introduction: Open appendectomy (OA) and laparoscopic appendectomy (LA) are the choices of treatment for acute appendicitis. However, laparoscopic approach is emerging for the benefits it provides, but it also sometimes may has some drawbacks like OA including fistula. Objective: This retrospective study aims to investigate the management of fistula in 50 post appendicectomy fistula patients. Methods: A retrospective study was done at MH Samorita Medical College & Hospital, Hi-Tech Surgicare Hospital & Piles Centre, Savar Specialized Hospital and Lab Zone Hospital Savar, Bangladesh during January 2019 to December 2023 from January 2019 to December 2023, among the patients who had underwent laparoscopic appendicectomy and open appendicectomy. The total study population was 50, among which 33 (66%) patients were in open appendectomy and 17 (34%) were in laparoscopic appendectomy. The patients’ age group included 10 years to 50 years of both male and female patients. P< 0.005 was considered significant in this study. Results: Out of total study population, 33 were from OA (66%) and 17 were from LA (34%) group. Most of the study patients were male, aged 21-30 years age group. Fistulogram found to be the commonly use method to diagnose fistula. Tuberculosis was found to be the frequent cause of post appendicectomy fistula. Conclusion: Post appendicectomy seems to have different outcomes with some adverse impact, fistula is one of them. The present study finds that the chances of post appendicectomy fistula is less in LA group compared to OA. Proper study and better investigation may bring this to null with time.
