To investigate the feasibility, safety and clinical efficacies of the combinations of the endoscopic and laparoscopic procedures was employed in the treatment of colorectal polyps.

From Apr. 2013 to Mar. 2016, 59 cases of laparoscopic partial colonoscopy colorectal polyp patients with partial resection and a stitch were performed in the second clinical medical college, Jinan University, Shenzhen people′s hospital of gastrointestinal surgery: knotless self-retaining suture was used in 34 cases(knotless self-retaining suture was used group), and traditional absorbable suture was used in 25 cases (traditional absorbable suture was used group). Respectively to compare two groups of general situation, time of interpretative suture intestines, intraoperative blood loss, postoperative intestinal function recovery time, postoperative hospital stay and the incidence of postoperative complications such as anastomotic leakage and other indicators whether there is a statistically significant difference.

Two groups in the age distribution, sex ratio, intraoperative blood loss, postoperative intestinal function recovery time, postoperative hospitalization days and the incidence of postoperative complications such as anastomotic leakage and there were no statistically significant difference between the indicators(P>0.05). However, the two groups had difference was statistically significant on the suture time , the time of interpretative suture intestines in group A is less than that of group B [13.96±3.19) min vs (25.68±10.72) min](P<0.05).

Knotless agnail line in laparoscopic combined intraoperative colonoscopy in the treatment of colorectal polyps is safe and feasible. In the laparoscopic intraoperative colonoscopy in the treatment of colorectal polyps, knot agnail line relative to the general can absorb line can shorten the time of interpretative suture intestines, but also not increase the incidence of postoperative anastomotic leakage and other complications, etc.
