Ampullary tumors are diagnosed by endoscopic biopsy of the ampulla of Vater. We encountered a rare case of acute pancreatitis following endoscopic biopsy of the ampulla. A 53-year-old man referred to our hospital for detailed examination of a suspected tumor of the ampulla of Vater. We conducted endoscopic biopsy from the ampulla. He developed severe abdominal pain four hours after the procedure. The serum amylase and serum lipase were elevated and abdominal computed tomography (CT) revealed pancreatic enlargement and diffuse stranding of the peri-pancreatic fat, compatible with the findings of acute pancreatitis. We diagnosed the patient as having acute pancreatitis caused by endoscopic biopsy of the ampulla of Vater. Conservative therapy improved his condition, however, a large pancreatic walled-off necrosis (WON) developed. Therefore, we performed endoscopic ultrasonography (EUS)-guided cyst drainage on the 74th day after admission. The WON diminished gradually in size and the symptoms disappeared, and the patient was discharged in good physical condition on the 137th day after admission. In this case, the ampullary biopsy may have caused mucosal edema or intraductal hematoma, resulting in pancreatic duct obstruction. It is important for endoscopists both to be aware of this potential complication following endoscopic biopsy of the ampulla and to inform the patients about possible complications of this procedure.

Objective We attempted to elucidate the clinical features of chronic hepatitis C patients who develop hepatocellular carcinoma (HCC) after achieving a sustained viral response (SVR) to interferon (IFN) therapy. Methods The clinical features of 130 patients at 19 hospitals who developed HCC after obtaining an SVR were retrospectively reviewed. Results Overall, 107 (82%) of the 130 patients were men, with 92 (71%) being ≥60 years of age and 76, 38 and 16 developing HCC within 5, 5-10 and 10-16.9 years after IFN therapy, respectively. Before receiving IFN therapy, 92 (71%) patients had cirrhosis and/or a low platelet count (<15×104 cells/μL). Lower albumin (<3.9 g/dL) and higher alpha fetoprotein (AFP) (≥10 ng/mL) levels were identified in a multivariate analysis to be independent variables of the development of HCC within five years after IFN therapy. Among 4,542 SVR patients, HCC occurred in 109 (2.4%) during a 5.5-year follow-up period, thus resulting in an occurrence rate of 4.6% for men and 0.6% for women. Conclusion SVR patients with lower albumin or higher AFP levels require careful assessments to prevent early HCC development after IFN therapy. HCC occurrence within >10 years of IFN therapy is not uncommon, and the risk factors remain uncertain, thus suggesting that all SVR patients should undergo long-term follow-up examinations for HCC development.
