Rectal carcinoid rumors are often diagnosed assubmucosal tumors on radiological or endoscopicexaminations.Usually,its definite size and character,theinfiltration of muscularis propria and vessels can not becorrectly diagnosed preoperatively.In recent years,endoscopic ultrasonography(EUS)has been used in thediagnosis of submucosal tumors of the gastrointestinaltracts.Conventional endoscopic polypectomy allowslocal excision of local tumors,but is often associated withrumor involvement of the resection margin thatnecessitates further interventions.In this study wedetermined the characteristics of rectal carcinoid tumorsby using EUS,and evaluated endoscopic submucosalresection(ESMR)in treating rectal carcinoid tumors.

Conventional endoscopic polypectomy allowslocal excision of local tumors, but is often associated with rumor involvement of the resection margin that necessitates further interventions. In this study wedetermined the characteristics of rectal carcinoid tumorsby using EUS, and ascending endoscopic submucosal recuperation (ESMR) in treating rectal carcinoid tumors.
