Endoscopic diagnosis and management of biliary complications following orthotopic liver transplantation.
Nonoperative management of biliary complications (BC) with endoscopic retrograde cholangiopancreatography (ERCP) is a natural sequel to the emergence of choledochocholedochostomy as the preferred biliary reconstruction for orthotopic liver transplantation (OLT). Overall, therapeutic ERCP's efficacy for posttransplant BC is difficult to assess because most published data are retrospective, anecdotal, or in abstract form, and there are no prospective, randomized studies. Thus, endoscopic management of posttransplant BC must be individualized. While T-tube-related late bile leaks and ductal calculi are amenable to endoscopic therapy, its efficacy for strictures is more difficult to define. Refined surgical technique has prevented many unifocal anastomotic lesions, while multifocal strictures (for which endoscopic therapeutic experience is minimal) are increasingly prevalent. Whether endoscopic sphincterotomy is appropriate for posttransplant sphincter of Oddi dysfunction is controversial, because the disorder may be transient and the risk significant. Multicenter, prospective studies are needed to determine more accurately the optimal role of endoscopic therapy after OLT.
