Clinical evaluation of endoscopic full-thickness resection assisted by dental floss traction in treatment of gastric submucosal tumors / 中国内镜杂志

ABSTRACT

Objective To evaluate the clinical efficacy and safety of endoscopic full-thickness resection assisted by dental floss traction in treatment of gastric submucosal tumors. Methods Those patients with gastric submucosal tumors from January 2016 to September 2016 were enrolled in the study. All patients were treated with endoscopic full-thickness resection assisted by dental floss traction. The en bloc resection rate, procedure time were analyzed. Complications such as bleeding and perforation were observed in the procedures. All patients were followed up 3-6 months for evaluation of efficacy and safety. Results 96 patients were recruited into the study. The average surgery time of 26.7 min (20 ~ 55 min), the success rate and the en bloc resection rate was 100.0%. The average tumors sizes was 1.2 cm (0.8 ~ 2.5 cm). The intraoperative bleeding occurred in 1 patient, the incidence rate of bleeding was 1.0% (1/96). The tumors were located cardia in 13 patients (13.5%), gastric fundus in 46 patients (47.9%), in gastric body in 33 patients (34.3%), in antrum in 2 patients (2.1%), in gastric angle in 2 patients (2.1%). Pathological results of interstitial tumor in 62 patients (64.6%), leiomyoma in 31 patients (32.3%), calcifying fibroma in 1 patients (1.0%), ectopic pancreas in 2 patients (2.1%). The median hospital stay was 4 days (3 ~ 7 d). No complications such as fever, abdominal pain were found during during the follow-up of 3 ~ 6 months. Conclusion Endoscopic full-thickness resection assisted by dental floss traction in treatment gastric submucosal tumors is effective and safe.
