Anatomical Challenges Associated With Conversion of Laparoscopic Cholecystectomy to Open Surgery

Abstract

Background: Laparoscopic cholecystectomy is the recommended surgery for symptomatic gallstone disease and cholecystitis, due to diminished postoperative pain, reduced hospital stay and quicker recovery. But, if anatomical distortion, inflammation, or adhesions or unclear biliary anatomy is present, laparoscopic dissection may be impossible, and conversion to open cholecystectomy may be necessary.

Objective: To determine the anatomical factors associated with conversion from laparoscopic to open cholecystectomy among patients undergoing cholecystectomy.

Methods: The descriptive cross sectional study was carried out in the department of surgery at Rawal Institute of Health Sciences, Islamabad from January 2025 to January 2026. Through non-probability consecutive sampling, 72 patients who were given a diagnosis of symptomatic gallbladder disease and were undergoing laparoscopic cholecystectomy were included. Data on a structured proforma were collected on the following: demographic data, clinical presentation, ultrasound data, and anatomical factors during surgery, conversion status, and postoperative outcomes. The patients were divided into a completed laparoscopic surgery group and a converted open surgery group. The data were analyzed on SPSS version 25. Analyses of a categorical variable were conducted using the chi-square (or Fisher's exact) test, and analyses of continuous variables were conducted using the independent sample t-test. A P value of < 0.05 was defined as statistically significant.

Results: Out of 72 patients, laparoscopic cholecystectomy was completed successfully in 61 (84.7%) patients, while 11 (15.3%) required conversion to open surgery. Dense adhesions were observed in 72.7% of converted cases compared with 19.7% of completed laparoscopic cases. Other significant anatomical factors included frozen Calot’s triangle, difficult identification of the cystic duct and artery, impacted Hartmann’s pouch stone, contracted or fibrosed gallbladder, empyema, gangrenous gallbladder, bleeding from the cystic artery or liver bed, and failure to achieve the critical view of safety. The converted group also had longer operative time and hospital stay.

Conclusion: Conversion from laparoscopic to open cholecystectomy was mainly associated with difficult anatomy and inflammatory distortion around the gallbladder and Calot’s triangle. Dense adhesions, frozen Calot’s triangle, impacted Hartmann’s pouch stone, contracted gallbladder, and failure to achieve the critical view of safety were the most important factors. Early conversion should be considered a safe surgical decision when laparoscopic dissection becomes hazardous.
