Abstract
A 62-year-old man with chronic hepatitis B was admitted to our hospital with abdominal pain. Computed tomography (CT) demonstrated superior mesenteric thrombosis and jejunum with severely thickened wall. Thrombolysis via the superior mesenteric artery using urokinase and systemic anticoagulant therapy using heparin were started immediately and improved the symptom and thrombosis. However, ileus occurred on day 75 after the onset of superior mesenteric vein thrombosis (SMVT). CT demonstrated a jejunal stricture of 2cm. We chose balloon dilatation using a single-balloon endoscope and treatment was successful. He has remained asymptomatic during the one-year follow-up period. We describe for the first time a case of effective treatment with endoscopic balloon dilatation for a jejunal stricture after anticoagulant and thrombolytic therapy for SMVT.
