Efficacy and safety of the duette multiband mucosectomy for esophageal submucosal tumors

Objective To investigate clinical efficacy and safety of endoscopic multiband mucosectomy(EMBM) for esophageal submucosal tumors(SMTs). Methods Data of 51 patients with SMTs diagnosed between Jan 2012 and Aug 2014 were retrospectively studied. Of the 51 patients, 33 patients(34 lesions) received EMBM and 18 patients received endoscopic submucosal resection(ESMR). The operation success rates, complete resection rates, procedure time, complications and the follow-up of group EMBM and group ESMR were compared. Results All of 51 cases had successful endoscopic treatment with no perforation, infection or obvious bleeding. Follow-up showed no recurrence after operation. Compared with group ESMR, group EMBM had higher complete resection rate[97.1%(33/34) VS 61.1%(11/18), P=0.010], shorter operation time[(6.3±1.8)min VS (21.4±3.8)min, P=0.001] and lower complication rate[6.1%(2/33) VS 27.8%(5/18), P=0.024]. Conclusion EMBM is simple, safe and effective for treating SMTs originating from muscularis mucosa or submucosa which are less than 2.0 cm in diameter.
