Perioperative strategies for patients undergoing subtotal cholecystectomy: a single-center retrospective review of 102 procedures

Abstract

BackgroundCalculous gall bladder disease is often handled by laparoscopic cholecystectomy. In cases where a safe dissection of the hepatocystic triangle cannot be carried out, a subtotal cholecystectomy (STC) may be performed. The perioperative management of patients undergoing STC is characterized by limited evidence. This large single-center series explores some of the perioperative aspects and outcomes after STC.Materials and methodsThe study population includes all patients who underwent STC at Oslo University Hospital (Ullevål and Aker Hospitals) from 01.01.2014 to 30.09.2020. A STC was defined as a cholecystectomy where there was a failure to control the cystic duct during surgery. Study variables included demographic data, comorbidities, previous biliopancreatic disease, indication for surgery, perioperative information, subsequent interventions and outcome data.ResultsDuring the study period, 2376 cholecystectomies were performed, and 102 (4.3%) were categorized as STC. Of all patients with STC, 48 (47.1%) had an intra- or postoperative ERCP during the index hospital admission. The indication for ERCP was bile leak in 37 (42.6%) of the cases. The bile leak resolution rate was 60.0 % in intraoperative ERCP vs 95.7% in postoperative ERCP. Among the STC patients, there were no injuries to the central bile ducts. Later, one patient has undergone a remnant cholecystectomy, following fenestrating STC.ConclusionSTC was a safe bailout strategy for dissection in the hepatocystic triangle in difficult cholecystectomies. Intraoperative ERCP increased procedure time and was associated with a lower rate of leak resolution, as compared to postoperative ERCP.
