Subtotal cholecystectomy: is it a safe option for difficult gall bladders?

Abstract

Subtotal cholecystectomy (STC) is an alternative to total cholecystectomy (TC) in patients with severe inflammation/adhesions around the hepatocystic triangle. This study aimed to evaluate the safety profile of STC. We retrospectively reviewed all patients who had STC at our unit between February 2009 and August 2019. STC was divided into two types, reconstituting (R-STC) and fenestrating (F-STC), depending on whether the gall bladder remnant was closed or left open. Patients who had cholecystectomy for gall bladder malignancy or as part of another operation were excluded from the study. A total of 5,664 patients underwent cholecystectomy during the study period. Of these, 97 (1.7%) underwent STC. The laparoscopic to open conversion rate was high at 48.8% (47 cases), as was the overall postoperative complication rate (45.4%, 44 cases). No patient suffered iatrogenic bile duct injury. Nineteen patients (19.6%) suffered postoperative bile leak. This was significantly higher in patients who had STC in the acute setting (41% vs 13% for elective STC cases; p=0.04). There was no significant difference in rate of bile leak or other complications between R-STC and F-STC types. The 90-day readmission rate was 8.2% (8 cases). No mortalities were recorded within 90days post STC. STC seems to be an effective technique to avoid bile duct injury in difficult cholecystectomy cases. However, the perioperative morbidity associated with STC is relatively high. Surgeons should be aware of the risks of STC and take appropriate steps to minimise them.
