Background: In the setting of difficult dissection of Calot's triangle during laparoscopic cholecystectomy, conversion is commonly advocated. An alternative approach aimed at preventing bile duct injury is laparoscopic partial cholecystectomy (LPC). The safety and efficacy of this procedure are unclear.
Methods: A systematic review of the literature was performed independently by three researchers. The outcomes were conversion rate, hospital length of stay (LOS), bile duct injury, bile leak, symptomatic gallstones in the remnant gallbladder, need for reoperation, postoperative endoscopic retrograde cholangiopancreaticography (ERCP), percutaneous intervention, and mortality.
Results: The review included 15 publications, which reported on 625 patients. Four different operative techniques could be distinguished. Conversion to open (partial) cholecystectomy was performed in 10.4 % of the cases. The median LOS was 4.5 days (range, 0-48 days). The most common complication was postoperative bile leak, which occurred in 66 patients (10.6 %). One case of bile duct injury occurred. During the follow-up period, 2.2 % of the patients experienced recurrent symptoms of gallstones. Eight patients (2.7 %) underwent reoperation. Postoperative ERCP was performed for 26 (7.5 %) of 349 patients. A percutaneous intervention was performed for 5 (1.4 %) of 353 patients. Three deaths were described in the reviewed series (1 of pulmonary sepsis and 2 of myocardial infarctions). A rough comparison showed that fewer bile leaks, less need for ERCP, and less recurrent symptoms of gallstones seemed to occur when the cystic duct and gallbladder remnant were closed.
Conclusions: Literature concerning LPC is scarce. Four different LPC techniques can be distinguished. When a difficult gallbladder is encountered during LC, LPC seems to be a safe and feasible alternative to conversion. Closing of the cystic duct, gallbladder remnant, or both seems to be preferable.
