Endoscopic mucosal resection of laterally spreading lesions involving the ileocecal valve: technique, risk factors for failure, and outcomes (original) (raw)

Endoscopy, 2015

Abstract

Background and study aims: Endoscopic mucosal resection (EMR) of laterally spreading lesions (LSLs) involving the ileocecal valve (ICV) is technically demanding. Conventionally, these lesions are considered too challenging for endoscopic therapy and are primarily managed surgically. The aims of the study were to describe effectiveness, safety, and outcomes following EMR of LSLs at the ICV. Patients and methods: This was a single-center, prospective, observational, cohort study performed at an academic, tertiary referral center. Patients undergoing EMR for LSLs ≥ 20 mm involving the ICV were recruited over a 5-year period. Standard or cap-assisted colonoscopy with inject-and-resect EMR technique was performed with standardized post-EMR management. Procedural success, safety, and outcomes compared with non-ICV LSLs managed during the same period were analyzed. Results: A total of 53 patients with ICV LSLs were referred for EMR (median age 69 years; median lesion size 35.0 mm; 52.8 % f...
