BACKGROUND Double-balloon endoscopic retrograde cholangiography (DB-ERC) is widely performed for biliary diseases after reconstruction in gastrointestinal surgery, but there are few reports on DB-ERC after hepatectomy or living donor liver transplantation (LDLT). AIM To examine the success rates and safety of DB-ERC after hepatectomy or LDLT. METHODS The study was performed retrospectively in 26 patients (45 procedures) who underwent hepatectomy or LDLT (liver operation: LO group) and 40 control patients (59 procedures) who underwent pancreatoduodenectomy (control group). The technical success (endoscope reaching the choledochojejunostomy site), diagnostic success (performance of cholangiography), therapeutic success (completed interventions) and overall success rates, insertion and procedure (completion of DB-ERC) time, and adverse events were compared between these groups. RESULTS There were no significant differences between LO and control groups in the technical [93.3% (42/45) vs 96.6% (57/59), P = 0.439], diagnostic [83.3% (35/42) vs 83.6% (46/55), P = 0.968], therapeutic [97.0% (32/33) vs 97.7% (43/44), P = 0.836], and overall [75.6% (34/45) vs 79.7% (47/59), P = 0.617] success rates. The median insertion time (22 vs 14 min, P < 0.001) and procedure time (43.5 vs 30 min, P = 0.033) were significantly longer in the LO group. The incidence of adverse events showed no significant difference [11.1% (5/45) vs 6.8% (4/59), P = 0.670]. CONCLUSION DB-ERC after liver operation is safe and useful but longer time is required, so should be performed with particular care.
