Endoscopic retrograde cholangiopancreatography in patients with biliary complications after orthotopic liver transplantation: outcomes and complications.
Biliary complications after orthotopic liver transplantation (OLT) still remain a major cause of morbidity and mortality. The most frequent complications are strictures and leakages in OLT cases with duct-to-duct biliary reconstruction (D-D), which can be treated with dilatation or stent placement during endoscopic retrograde cholangiopancreatography (ERCP), although this procedure is burdened with potentially severe complications, such as retroperitoneal perforation, acute pancreatitis, septic cholangitis, bleeding, recurrence of stones, strictures due to healing process. The aim of the study was to analyze the outcome of this treatment and the complications related to the procedure. Among 1634 adult OLTs, we compared postprocedural complications and mortality rates with a group of 5852 nontransplanted patients (n-OLTs) who underwent ERCP. Of 472 (28,8%) post-OLT biliary complications, 319 (67.6%) occurred in D-D biliary anstomosis cases and 94 (29.5%) patients underwent 150 ERCP sessions. Among 49/80 patients (61.2%) who completed the procedure, ERCP treatment was successful. Overall complication rate was 10.7% in OLT and 12.8% in n-OLT (P = NS). Compared with the n-OLT group, post-ERCP bleeding was more frequent in OLT (5.3% vs 1.3%, P = .0001), while the incidence of pancreatitis was lower (4.7% vs 9.6%, P = .04). Procedure-related mortality rate was 0% in OLT and 0.1% in n-OLT (P = NS). ERCP is a safe procedure for post-OLT biliary complications in the presence of a D-D anastomosis. Morbidity and mortality related with this procedure are acceptable and similar to those among nontransplanted population.
