Treatment of Multiple Rectal Carcinoids by Endoscopic Mucosal Resection Using a Device for Esophageal Variceal Ligation

Abstract

A 54-year-old man was referred to our hospital because of lower abdominal discomfort. Total colonoscopic examination was performed and four protruding yellow-white lesions, 6 mm or less in diameter, were detected in the rectum (Figure [1] a). At endoscopy it was suspected that these lesions were rectal carcinoids and this diagnosis was confirmed by histological examination of biopsy specimens. Endoscopic ultrasonography demonstrated that the carcinoid tumors were localized within the submucosal layer (Figure [1] b). Abdominal ultrasonography and computed tomography did not show any evidence of abdominal lymph node swelling or of metastatic lesions in the liver.
