Feasibility of endoscopic retrograde cholangiopancreatography-related procedures in hemodialysis patients

Background and Aim The opportunities of endoscopic retrograde cholangiopancreatography (ERCP)‐related procedure for hemodialysis (HD) patients have been increasing recently. However, the complication rate of ERCPs in HD patients has not been evaluated sufficiently. We aimed to clarify the feasibility of ERCPs in HD patients. Methods We retrospectively reviewed 76 consecutive ERCPs for HD patients between January 2005 and December 2012 in one university hospital and three tertiary‐care referral centers. Endoscopic sphincterotomy (EST) was performed in 21 HD patients. We evaluated the incidence and risk factors for complications of all ERCPs and EST in HD patients. Results The incidence of pancreatitis, cholangitis, and cardiopulmonary complications for ERCPs in HD patients was 7.9% (6/76), 1.3% (1/76), and 1.3% (1/76), respectively. The mortality rate was 2.6% (2/76), and it occurred after acute pancreatitis in one patient and pneumonia in the other patient. The incidence of hemorrhage and pancreatitis with EST was 19% (4/21) and 4.8% (1/21), respectively. The duration of HD was significantly longer in the patients with hemorrhage after EST than without (19.5 vs 6 years; P = 0.029). Conclusions ERCP is feasible in HD patients. However, EST is not advisable because of the high hemorrhage rate, particularly for patients with a long duration of HD.
