Is subtotal cholecystectomy safe and feasible? Short and long-term results.

BACKGROUND Cholecystectomy is one of the most commonly performed surgical procedures. However, it may result in some unpleasant conditions such as bile duct injury (BDI), bile leak and vessel injury. Subtotal cholecystectomy (SC), which has been introduced as an alternative method for reducing the complication rates, has been reported to have lower risk of BDI when compared to total cholecystectomy. This study aimed to evaluate the indications for SC, its early and late complications and their management, and the risk factors affecting the bile leak. METHODS Fifty-seven patients who underwent SC were included in the study, and their medical records were retrospectively reviewed. RESULTS Thirty-three patients were male (57.9%) and the mean age was 64.84 ± 11.35 (range: 29-86). All patients had at least one episode of cholecystitis. Forty-seven (82.5%) patients underwent surgery under emergency conditions. Postoperative bile leak/fistula, surgical site infection and fluid collection were developed in 12 (21.1%), eight (14%) and six (10.5%) patients, respectively. Leaving the remnant tissue pouch open, presence of comorbidity and emergency operative condition were found to increase the risk of leak development (p<0.001). During the average follow-up of 49 months (range: 13-98), symptomatic choledocholithiasis, symptomatic gallstones in the remnant tissue and incisional hernia were detected within the first year of surgery in three (5.3%), four (7%) and seven (12.3%) patients, respectively. CONCLUSIONS Although SC is not an equivalent to total cholecystectomy, its vital benefit in providing a major advantage by lowering the risk of BDI should be considered in difficult cases.
