Trends and Outcomes of Cholecystectomy; a comparative study of open and laparoscopic cholecystectomy, a Three Year Experience in a Teaching Hospital, Addis Ababa
Objective: This study is aimed to assess the trends and outcomes of cholecystectomy in a teaching hospital in Addis Ababa by comparing the recently introduced laparoscopic cholecystectomy with the open method using different variables.
Methods: A comparative retrospective cross sectional study was conducted and all patients who have undergone cholecystectomy for gallstones were included. Data was collected through chart review and analyzed by SPSS version 20. Independent sample T-test was used to compare the operation time and the post operative hospital stay of patients of both groups.
Results: A total of 471 cholecystectomies were performed out of which 32% were laparoscopic. The female to male ratio was 5.12:1 with mean age of 41.64±12.45 years. The mean operation time was 52.96 minutes for the open group and57.59 minutes for the laparoscopic group. The post operative hospital stay was 3.42 days and 2.45 days for the open and laparoscopic group respectively. There was no statistically significant difference in operation time, morbidity and mortality between the two groups. However, the post operative hospital stay was significantly shorter for the laparoscopy group. The conversion rate from laparoscopic cholecystectomy was 2.6%.
Conclusion: Although laparoscopic cholecystectomy is introduced recently in our institution, the above results show that it has encouraging outcome. Hence, future effort should be directed towards expanding this service to more health institutions in the country.
