Efficacy and safety of the duette multiband mucosectomy for esophageal submucosal tumors / 中华消化内镜杂志

ABSTRACT

Objective To investigate clinical efficacy and safety of endoscopic multiband mucosec-tomy(EMBM)for esophageal submucosal tumors(SMTs).Methods Data of 51 patients with SMTs diag-nosed between Jan 2012 and Aug 2014 were retrospectively studied.Of the 51 patients,33 patients(34 le-sions)received EMBMand 18 patients received endoscopic submucosal resection(ESMR).The operation success rates,complete resection rates,procedure time,complications and the follow-up of group EMBMand group ESMR were compared.Results All of 51 cases had successful endoscopic treatment with no perfora-tion,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.
