Endoscopic snare excision of a major duodenal papillary tumor.

BACKGROUND/AIMS Tumors of the duodenal papilla include hyperplasia, adenoma, carcinoma in adenoma, and carcinoma. Since the duodenal papilla has special anatomical characteristics and treatment involves major intervention, a correct preoperative diagnosis is essential for successful treatment. METHODS In patients with adenoma or early carcinoma of the papilla, endoscopic snare excision is indicated for complete removal of the tumor. Postoperative pancreatitis and cholangitis are major complications of endoscopic techniques, and we describe here in detail our procedure aiming to reduce the incidence of such complications. RESULTS Endoscopic snare excision of a tumor of the major duodenal papilla was carried out in 36 patients. Bleeding after endoscopic excision occurred in 6 cases (17%), postoperative pancreatitis in 11 cases (30%), and postoperative cholecystitis in 1 case (3%). All patients recovered from the complications within 1 week. CONCLUSION Our results suggest that the procedure for endoscopic snare excision used to resect major papillary tumors is safe and helps to prevent serious complications.
