Inlfuence of injection color regents concentration on completed resection rate, operation time and injection volume of patients with intestinal tumor by ESD / 中国内镜杂志

ABSTRACT

Objective To investigate the influence of injection color regents concentration on completed resection rate, operation time and injection volume of patients with intestinal tumor by ESD.Methods 90 elderly patients with intestinal tumor by ESD were chosen from June 2013 to June 2016. They were randomly divided into 3 groups including A group (30 patients) with glycerin fructose used alone, B group (30 patients) with glycerin fructose combined with 2% mythylene blue on the basis of glycerin fructose and C group (30 patients) with glycerin fructose combined with 4% mythylene blue on the basis of glycerin fructose; and the completed resection rate of tumor, operation time, injection volume and complication incidence in the peri-operative period of 3 groups were compared.Results There was no signiifcant difference in the completed resection rate of tumor among the 3 groups (P < 0.05). The operation time and injection volume of C group were signiifcant better than A group and B group (P< 0.05). There was no signiifcant difference in operation time and injection volume between A group and B group (P < 0.05). There was no signiifcant difference in the complication incidence in the peri-operative period among the 3 groups (P < 0.05).Conclusion Compared with glycerin fructose used alone and glycerin fructose combined with 1% mythylene blue for 2 mg, glycerin fructose combined with 1% mythylene blue for 4 mg by intestinal submucosal injection on patients with intestinal tumor by ESD can efifciently shorten the operation time and reduce the injection volume.
