Abstract

Introduction: Laparoscopic Subtotal Cholecystectomy (LSTC) is a bailout procedure that is undertaken when it is not safe to proceed with a laparoscopic total cholecystectomy due to dense adhesions in Calot’s triangle. The main aim of this review was to understand the early (≤30 days) and late (> 30 days) morbidity and mortality of LSTC.
Methods: A literature review of PUBMED (Medline), Google scholar and EMBASE was conducted from 1985 to December 2020 to identify all studies on LSTC. A systematic review was then performed.
Results: 45 studies were identified, with a total of 2166 patients. Mean age was 55 +/- 15 years with 51% females; 53% (n=390) were elective procedures. The conversion rate was 6.2% (n=135). Most common indication was acute cholecystitis (n=763). Different techniques were used with the majority having a closed cystic duct/gallbladder stump (n=1188, 71%). The most common closure technique was intracorporeal suturing (53%) followed by endoloop closure. There were a total of four, 30-day mortality in this review. Early morbidity (≤30 days) included bile duct injury (0.23%), bile leak rates (18%), intra-abdominal collection (4%). Reoperation was reported in 23 patients (1%), most commonly for unresolving intra-abdominal collections and failed ERCP to control bile leak. Long term follow-up was reported in 30 studies with a median follow up period of 22 months. Late morbidity included incisional hernias (6%), CBD stones (2%), and symptomatic gallstones in 4% (n=41) with 2% (n=22) requiring completion of cholecystectomy.
Conclusion: LSTC is an acceptable alternative in patients with “difficult” Calot’s triangle.
