Abstract

EMR is a viable alternative to surgery for removal of large mucosal neoplastic lesions of the entire GI tract. Few studies have, however, been published on the safety, efficacy, and technical aspects of EMR in the duodenum. Our purpose was to evaluate the efficacy and safety of EMR of large (>15 mm) duodenal adenomas. Retrospective evaluation of a defined patient cohort. Tertiary academic referral center. Patients with large (>15 mm) sporadic nonampullary duodenal adenomas managed by a standardized technique who were referred by other specialist endoscopists for endoscopic treatment. Five-year data from patients undergoing EMR for large duodenal adenomas were reviewed retrospectively. Immediate and delayed complications were recorded. Twenty-one lesions were removed by EMR in 23 patients (mean age 62.2 years, 13 female, 10 male). The mean size of lesions resected was 27.6 mm (median 20 mm, range 15-60 mm). Post-EMR histologic examination revealed mucosal adenocarcinoma in 1, low-grade tubulovillous adenoma (TVA) in 16, high- or focal high-grade TVA in 3 patients, and 1 with both high-grade TVA and carcinoid. EMR was performed successfully in 18 patients during a single session. Two patients required 2 sessions and 1 required 3 ...Continue Reading

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
