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).
To examine the success rates and safety of DB-ERC after hepatectomy or LDLT.
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.
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].
DB-ERC after liver operation is safe and useful but longer time is required, so should be performed with particular care.
Core tip: The utility of double-balloon endoscopic retrograde cholangiography (DB-ERC) has been widely reported, but the success rates and the examination time varied by reconstruction methods. There are no reports about DB-ERC after hepatectomy, but if the liver was resected, DB-ERC will be more difficult. We compared the elements of DB-ERC after hepatectomy or living donor liver transplantation with control group (after pancreatoduodenectomy). The success rates and incidence of adverse events were equivalent, but the insertion and procedure time were significantly longer. We discuss the difficulty of DB-ERC after hepatectomy.
