RESUMO
Objective To evaluate the perforation repair method of purse-string suture with single channel after gastroscopy endoscopic submucosal resection (ESD) in treating gastric submucosalal stromal tumor originating from muscularis propria lay of gastric fundus. Methods 15 patients with GIST from gastric fundus muscularis propria were treated with ESD. The diameters of tumors were from 1.5 ～ 3.5 cm. Purse-string suture with single channel gastroscopy was performed for the gastric wall perforation during ESD. Results All patients underwent repair successfully. The procedure time was 10 ～ 15 min. No severe complications occurred. Conclusion Purse-string suture with single channel gastroscopy is a feasible and effective perforation repair method during ESD of gastric fundus.
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.
RESUMO
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.
