Abstract

Objective: To determine the frequency of conversion to open cholecystectomy in elective cases that underwent laparoscopic
procedure.
Material and Methods: This was a retrospective study conducted in surgical department of Northwest General hospital
and research center, Peshawar-Pakistan. All the cases were performed by a single experienced general and laparoscopic
surgeon. All patients who underwent Laparoscopic Cholecystectomy (n =531) from September 2012 to April
2018 were identified from the medical records maintained in the Health Information and Management System. They
were considered as ‘converted’ if Laparoscopic Cholecystectomy was started initially but due to any reason it could
not be continued safely and a conversion to open was necessitated. Cases that required conversion to open procedure
in laparoscopic cholecystectomy were analyzed. the frequency of conversion to open and the factors responsible for
such conversion were also noted.
Results: A total of 531 patients were included in the study. The mean age was 48.82 years with a standard deviation
(SD) of 15.06 years. Gender distribution of patients was analyzed and showed that 115(21.7%) of those recruited were
male and the majority 416 (78.3%) were female. All patients were given standard laparoscopic surgery protocol under
general anaesthesia. Fifty four [n=54(10.2%)] patients were converted to open cholecystectomy whereas, 477(89.8%)
ended up with planned laparoscopic procedure.
Conclusion: The conversion rate to open cholecystectomy in laparoscopic cholecystectomy in our study was 10.2%.
The most common cause of conversion was gall bladder empyema and adhesion around gall bladder.
