PATIENTS AND METHODS Overall, 111 patients with portal hypertension and no previous history of digestive bleeding underwent esophagogastroduodenoscopy for detection of esophageal varices.(More)
Gastrobronchial fistula (GBF) is a serious complication following bariatric surgery, whose treatment by thoracotomy and/or laparotomy involves a high morbidity rate. We present the outcomes of endoscopic management for GBF as a helpful technique for its healing process. This is a multicenter retrospective study of 15 patients who underwent gastric bypass (n(More)

Our objective was to assess the safety and clinical effectiveness of 0.4% hydroxypropyl methylcellulose (HPMC) as a submucosal injectant for endoscopic mucosal resection. PATIENTS AND METHODS A prospective,(More)

CONTEXT Gastric mucosa-associated lymphoid tissue (MALT) lymphoma is clearly associated with Helicobacter pylori gastritis and can be cured with anti- H pylori therapy alone. The presence of t(11;18)(q21;q21) translocation is thought to predict a lower response rate to anti- H pylori treatment. OBJECTIVES To study the presence of t(11;18)(q21;q21) genetic(More)
