To evaluate effects of endoclip and endoloop in preventing postoperative hemorrhages after colorectal stalks polypectomy.

Eighty-five patients with polyps who came for consultation in our hospital from August 2015 to August 2018 and whose diameter of polyp was over 10mm as well as stalk diameter over 5mm were chosen to be research objects.The patients were divided into endoclip group and endocilp combined endoloop ligation group according to different pretreatment method of polyps.Polyps morphology, location, size, pathological types and intraoperative and postoperative hemorrhage rate, metal clips used, polyps residual rate, recurrence rate of polyps and other indexes of each patients were retrospectively analyzed.

Polyps morphology were mainly Yamada Ⅲ and Ⅳ, and mainly located in rectum and sigmoid colon in group A and B. There was no obvious difference regarding gender, age, top polyps, average diameter of Pericles in the two groups (P>0.05). Intraoperative hemorrhage rate as well as postoperative tardive hemorrhage rate in group A and B was (6.4% vs 0%, P>0.05) and (1.6% vs 2%, P<0.05) respectively. After endoscopic treatment, intraoperative and postoperative tardive hemorrhage were stopped. Three patients in group A suffered from residual in polyp base three months after operation.While three months after operation, surgical wounds of patients in group B were good and there was no residual in polyp base as well as no polyp recurrence.

For thick stalk polyps whose diameter was over 5mm, use of pretreated endocclip and endoloop could effectively prevent postoperative hemorrhage of polypoectomy and combined use of the two methods will be decided by the length and diameter of the pedicure according to detailed situations.
