A case of endoscopic submucosal resection of rectal NET with 2 lesions

Abstract

A 59-year old man had positive results of fecal occult blood test in the screening test. A colonoscopic examination revealed two elevated lesions looking like SMT, 10mm and 5mm in size, in the lower rectum. We performed diagnostic endoscopic submucosal resection with ligation device (ESMR-L) for a 10mm elevated lesion, performed diagnostic endoscopic mucosal resection (EMR) for a 5mm flat elevated lesion. The resected specimen of 2 lesions showed NET-G1, and the vertical and lateral margin were negative. A case of endoscopic submucosal resection of the multiple rectal NET is rarely reported.
