[A case of chronic hepatitis C with pancreas divisum and acute pancreatitis during combination treatment with telaprevir/peginterferon/ribavirin].

A 47-year-old man developed acute pancreatitis during combination treatment with telaprevir/peginterferon/ribavirin for chronic hepatitis C. Cessation of telaprevir, fasting, and gabexate mesilate improved the pancreatitis. Although peginterferon and ribavirin treatment was continued, there was no recurrence of the pancreatitis. Endoscopic retrograde cholangiopancreatography incidentally showed a pancreas divisum. We definitively diagnosed drug-induced acute pancreatitis due to telaprevir.
