Comparison of the effect of endoscopic multi-band mucosectomy and endoscopic mucosal resection for colorectal submucosal tumors

Abstract

Objective To compare the therapeutic effect and safety of endoscopic multi-band mucosetomy (EMBM) and endoscopic mucosal resection (ESMR) in the treatment of colorectal submucosal tumors. Methods From January 2012 to June 2014, the clinical data of 40 patients with colorectal submucosal tumors in Tengzhou Central People′s Hospital were divided into EMBM group (22 cases) and ESMR group(18 cases) according to different treatment method.The complete resection rate, operation time and complications were compared between the two groups. Results The complete resection rate of the EMBM group was 95.45%, which of the ESMR group was 94.44%, the difference between the two groups was not statistically significant (χ2=0.273, P>0.05). The operation time was shorter in the EMBM group[(31.3.5±4.0)min]than that in the ESMR group[(47.2±4.5)min), t=-15.194, P 0.05). All the patients were followed up for 3~24 months after operation, and no local recurrence occurred. Conclusion EMBM is safe and effective for colorectal submucosal tumors and the complications are less.
