橡皮圈与牙线牵引辅助内镜黏膜下剥离术治疗消化道 早癌的疗效比较.

Objective To compare the effect of rubber ring versus dental floss combined with hemoclipping assisted endoscopic submucosal dissection (ESD) in the treatment of early gastrointestinal tumor. Methods A total of 103 patients with early gastrointestinal cancer were divided into the rubber band traction group (rubber band group, n=51) and the dental floss traction assist group (dental floss group, n=52) according to different assisted traction techniques during ESD. The basic conditions of the two groups were compared before operation, as well as the amount of submucosal injection, installation time of the traction device, the amount of bleeding during operation, the time of operation, the delayed bleeding after operation, onetime complete resection rate of tumor, days in hospital after operation and complication rate at 72 hours after operation. The degree of postoperative pain (VAS pain Score), follow-up quality of life (SF-36 Score) and complications 12 months after operation were also recorded. Results The intraoperative submucosal injection volume, intraoperative bleeding volume, number of hemostatic clamp detachment, surgical time, complication rate 72 hour after operation and postoperative hospital stay were lower in the rubber band group than those in the dental floss group (P＜0.05). There was no significant difference in the number of delayed postoperative bleeding between the two groups (P＞0.05). After 12 months of follow-up, patients in the rubber band group had mild postoperative pain and good quality of life. The incidence of complications decreased within 12 months after surgery in the rubber band group (P＜0.05). Conclusion Compared with floss traction aid, rubber ring traction aid ESD can shorten the operation time and reduce postoperative complications, which is worth popularizing. [ABSTRACT FROM AUTHOR]
