BACKGROUND AND STUDY AIMS Although carcinoid tumors have malignant potential, complete resection can be curative if the lesion is located within the submucosal layer. In this study, we evaluated the effectiveness of endoscopic aspiration lumpectomy for the treatment of small rectal carcinoid tumors. PATIENTS AND METHODS Eight patients with rectal(More)
An unusual type of displacement of interventricular septum, the inverse of that found normally, was found by echocardiography in 3 cases: 2 with pulmonary arterial hypertension and 1 with constrictive pericarditis. In two cases catheterisation showed the haemodynamic picture of mitral obstruction, and in 1 case the typical findings on auscultation of mitral(More)
OBJECTIVES There is still much debate about the indications and best technique for endoscopy for the treatment of esophageal leiomyomas. We developed a novel technique for endoscopic aspiration lumpectomy and used it in patients with esophageal leiomyomas derived from the muscularis mucosae. METHODS Nine patients with esophageal leiomyomas were treated(More)
BACKGROUND Endoscopic diagnosis of duodenal elevated lesions is problematic for two reasons. Endoscopic biopsy often fails to confirm a histologic diagnosis of submucosal lesions. Moreover, a biopsy specimen is often insufficient to verify a differential diagnosis of mucosal lesions. In this study, we evaluated the usefulness of endosonography in the(More)
Two cases are reported of right medioventricular subinfundibular stenosis with intact intraventricular septum. This rare congenital malformation, also known as "double chambered right ventricle", and usually associated with an intraventricular communication, can only be diagnosed with certainly on the results of hemodynamic and angiographic studies which(More)
