Endosonographic preoperative evaluation for tumors of the ampulla of vater using endoscopic ultrasonography and intraductal ultrasonography.

Background/aims: In recent years, endoscopic snare papillectomy has been performed to treat tumors of the ampulla of Vater. This procedure requires accurate preoperative evaluation. In this study, we diagnosed the focal extension of such tumors by using endoscopic ultrasonography (EUS) and intraductal ultrasonography (IDUS), and examined the indications for endoscopic snare papillectomy.

Severe Acute Pancreatitis with Complicating Colonic Fistula Successfully Closed Using the Over-the-Scope Clip System.

A 44-year-old man presenting to our hospital emergency room with abdominal pain was hospitalized for hyperlipidemic acute pancreatitis. A pig-tail catheter was placed percutaneously to drain an abscess on day 22. Although the abscess improved gradually and good clinical progress was seen, pancreatic duct disruption was strongly suspected and endoscopic retrograde cholangiopancreatography was performed on day 90.

Right hepatic artery pseudoaneurysm complicating acute pancreatitis: a case report.

Objective: To report a rare case of right hepatic artery pseudoaneurysm complicating acute pancreatitis based upon imaging findings obtained before and after the development of pseudoaneurysm.

Clinical Presentation And Intervention: A 32-year-old male with a history of acute pancreatitis 1 year prior was readmitted for acute pancreatitis. Computed tomography (CT) and angiography after admission revealed pseudoaneurysm of the right hepatic artery.

Duct of Luschka diagnosed by sonography in a patient with bile duct carcinoma and intrahepatic bile duct dilatation.

The bile duct of Luschka (BDL) is an anatomic anomaly that is an important cause of bile leakage after bile duct surgery. We report a case of bile duct carcinoma with dilated BDL that was diagnosed by ultrasonography (US). An 83-year-old man presented with an obstructive jaundice.

Hepatic artery pseudoaneurysm after endoscopic biliary stenting for bile duct cancer.

We report a case of a pseudoaneurysm of the right hepatic artery observed 9 mo after the endoscopic placement of a Wallstent, for bile duct stenosis, which was treated with transcatheter arterial embolization. The patient presented with obstructive jaundice and was diagnosed with inoperable common bile duct cancer. A plastic stent was inserted endoscopically to drain the bile, and chemotherapy was initiated.
