Subtotal Cholecystectomy After Failed Critical View of Safety Is an Effective and Safe Bail Out Strategy.

BACKGROUND: Bile duct injury (BDI) is accompanied by significant morbidity and long-term impact in quality of life. Subtotal cholecystectomy (STC) is an alternative to prevent this outcome but is associated with other complications. The aim of this work is to demonstrate that BDI associated morbidity exceeds STC associated morbidity, underscoring STC as a reasonable bail out strategy.
METHODS: We compared 115 patients who underwent STC with 293 patients who were referred to our center with BDI type E1-E3 and underwent surgical repair. The groups were comparable because in both instances the surgeon had the opportunity to decide not to perform a total cholecystectomy once critical view of safety (CVS) was not achieved.
RESULTS: Bile leakage was found in 21% of the STC group with only one BDI (0.9%). More Accordion ≥ 4 were found in the STC group (10.4% vs 4.8%, p = 0.035); however, reoperations were more frequent in the BDI group (8.2% vs 0.9%, p = 0.006). No patient in the STC group required reintervention for completion cholecystectomy. After 3.8 years follow-up, 2.4% of patients had secondary biliary cirrhosis in the BDI group; none in the STC group.
CONCLUSIONS: Despite complications of STC, morbidity associated with BDI is much higher due to high long-term reoperation rate, in addition to secondary biliary cirrhosis. STC is a safe alternative that can prevent BDI if properly and timely performed in the context of difficult cholecystectomy.
