Subtotal Cholecystectomy in Preventing Major Complications in Difficult Cholecystectomy Cases: A Comprehensive Single Center Study

Abstract

ABSTRACT Background: Cholecystectomy is a commonly performed laparoscopic surgery but because of variability in anatomy, surrounding inflammation and fibrosis because of recurrent attacks of cholecystitis, can be a potentially difficult surgery. Laparoscopic total cholecystectomy in difficult gall bladder cases sometimes can cause severe complications. Laparoscopic subtotal cholecystectomy can be a bridge and a safe and feasible option between open subtotal cholecystectomy and laparoscopic cholecystectomy. Aim: To study indications, morbidity and clinical outcomes in patients undergoing subtotal cholecystectomy with laparoscopy or with open surgery. Settings and Design: It was a prospective observational study. Patients presenting with signs and symptoms of cholecystitis in either OPD or IPD and in emergency were included in this study. Materials and Methods: Total 38 patients who presented to our institute with clinical and ultrasonographic evidence of acute cholecystitis were included in the study. All patients underwent detailed and thorough clinical examination, laboratory investigations, ultrasonographic, and contrast enhanced computed tomography scan in selected patients. Based on intraoperative findings, decision of subtotal cholecystectomy either by laparoscopy or via open method was made. Various outcomes like intraoperative complications, postoperative complications and need of postoperative interventions, hospital stay, and returning to daily activity were observed and charted. Statistical Analysis: The data obtained were tabulated in Microsoft Excel and analyzed using SPSS version 17.0. Continuous variables were expressed as mean ± standard deviation value. Probability value (P value) was used to determine the level of significance. P value <.05 was considered as significant; P value <0.001 was considered as highly significant. Results: The common indications for subtotal cholecystectomy were severe cholecystitis with dense fibrous adhesions (97.4%), empyema (34.2%) or gangrenous gallbladder (31.6%), and Mirizzi syndrome (2.6%). Conversion rate was 21.1%. Morbidity rates were relatively low with subtotal cholecystectomy (bile leak 21.1%, sub hepatic collections 10.5%, retained stones 5.3%, paralytic ileus 18.4%, wound infection 7.9%, and common bile duct stricture 2.6%). Postoperative interventions were necessary in 18.4% of the cases (retained stones 5.3%, bile leak 7.9%, common bile duct stricture 2.6%, and subhepatic collection 2.6%). Mean duration of hospital stay was 7.5 days and returning to routine daily activity was 11.05 days. Conclusion: Subtotal cholecystectomy is a safe and feasible method for difficult gallbladder cases with a positive outcome. Laparoscopic subtotal cholecystectomy decreases the conversion rate in difficult gallbladder cases but it is not a substitute to open conversion if deemed necessary.
