RESUMO
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]. The incidence rate of hemorrhage in the EMBM group was 9.0%, which was significantly lower than 33.3% in the ESMR group (χ2=3.952, P<0.05). There was no statistically significant difference between the two groups in the incidence of postoperative colorectal stricture (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.
