Clinical value of dental floss traction-assisted endoscopic full-thickness resection for muscularis propria tumor in gastric fundus / 中华消化内镜杂志

ABSTRACT

Objective To explore the clinical value of dental floss traction-assisted endoscopic full-thickness resection ( EFTR) for muscularis propria tumor in gastric fundus. Methods Twenty-four patients with muscularis propria tumor in gastric fundus and undergoing EFTR with traction of dental floss from January to December in 2016 in Endoscopy Center of Zhongshan Hospital were enrolled in the trial group. Another 24 patients undergoing traditional EFTR from January to December in 2015 were enrolled in the control group. The control group was paired with the trial group according to tumor size. The differences in tumor resection time, hospitalization time, and complication rate were compared between the two groups. Results There were no significant differences in the mean age and gender composition between the two groups ( both P>0. 05) . The tumor resection time of the trial group was shorter than that of the control group ( 10. 8 ± 2. 8 min VS 19. 0 ± 4. 7 min, t = 7. 298, P<0. 05 ) . There was no significant difference in postoperative hospital stay between the two groups ( 3. 2 ± 0. 5 days VS 3. 2 ± 0. 5 days, t=0. 291, P=0. 772) . No postoperative delayed bleeding or perforation and other complications occurred in the two groups. Conclusion Dental floss traction-assisted EFTR is safe and effective to treatment of muscularis propria tumors in gastric fundus, which can expose the tumor boundary, so that the surgical level may be clearer to simplify the operation and reduce the tumor resection time.
