ARTICLE HIGHLIGHTS
Research background

Double-balloon endoscopic retrograde cholangiography (DB-ERC) is widely performed for biliary diseases after reconstruction in gastrointestinal surgery, but the success rates and the examination time varied by reconstruction methods.

Research motivation

There are few reports on DB-ERC after hepatectomy or living donor liver transplantation (LDLT), and we have experienced many cases requiring DB-ERC after hepatectomy or LDLT performed in our hospital.

Research objectives

The objective of this study is to examine the success rates and safety of DB-ERC after hepatectomy or LDLT, and to reveal the inherent difficulties of them.

Research methods

The study was performed retrospectively in patients who underwent DB-ERC after hepatectomy or LDLT [hereinafter referred to as liver operation (LO) group] and control patients after 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.

Research results

There were no significant differences between the LO and control groups for the success rates and the incidence of adverse events, but the median insertion time and procedure time were significantly longer in the LO group.

Research conclusions

DB-ERC is safe and useful for patients who underwent hepatectomy or LDLT. Although it may be difficult because of not only gastrointestinal reconstruction, but also lower liver volume: changes in running of gastrointestinal tract due to successive hepatomegaly: and easy bending upon insertion of the endoscope. So particular care with the endoscope and obtaining informed consent are essential before DB-ERC is performed.

Research perspectives

DB-ERC will be performed safely and easily for patients who underwent any gastrointestinal reconstruction.
