To compare the efficacy and safety of snare resection, endoscopic mucosal resection(EMR) and endoscopic submucosal dissection(ESD) for the treatment of gastrointestinal carcinoid.

We retrospectively analyzed the clinical data of 98 cases of pathologically confirmed gastrointestinal carcinoid from Jan. 2006 to Jun. 20l5.The clinical effect of snare resection (n=12), EMR(n=47) and ESD (n=39) for the treatment of gastrointestinal carcinoid was compared in terms of histologically complete resection rate, complications, and endoscopy follow-up for 6-36 months.

The rate of histologically complete resection was 78.57%(77/98); the rate of histologically complete resection in snare resection group was 66.67%(8/12), EMR group was 82.98% (39/47), ESD group was 76.92% (30/39), there is no significant difference in those three groups (P=0.463). Only l case had gastrointestinal perforation after ESD and no complication occurred in other patients. A total of 98 cases were followed up for 6-36 months and no recurrence was found.

Three endoscopic treatments are useful and safe methods for treatment of small gastrointestinal carcinoid which does not cross submucosal layer.
