Abstract：Objective: To study the characteristics of laparoscopic-assisted colorectal ectropion and drag-out surgery for colorectal cancer, and to provide references for optimizing surgical procedures and related research. Methods: 66 colorectal cancer patients who were treated in Shenyang anal and intestinal hospital from July 2018 to July 2020 were selected prospectively. 66 patients were divided into experimental group (n = 33) and control group (n = 33 cases) according to simple random grouping method. The control group performed laparoscopic rectectomy, and the experimental group performed laparoscopic colorectal ectropion and pull out operation. The therapeutic effect of the two groups was evaluated 5 days after operation, and the operation indexes (bleeding, operation time, defecation times per day, intestinal recovery time and hospitalization time), recurrence rate and complication rate were observed and compared. Results: The average daily defecation times in experimental group was (9.62±1.22) times, which was significantly higher than that in control group (5.22±0.80) times, the difference was statistically significant (t=8.032, P<0.05). Comparison of operation time between the two groups [(157.23±43.42) min vs (163.04±40.45) min], the difference was not statistically significant (t=0.074, P>0.05). The postoperative intestinal recovery time [(2.11±0.50) d], intraoperative blood loss [(46.32±4.27) ml] and hospitalization time [(48.44±3.50) d] in experimental groups were significantly shorter or shorter than those in control group [(4.58±0.68) d], [(68.42±6.57) ml] and [(67.90±5.91) d], with statistical significance (t=7.540, 6.279, 7.097, P<0.05).The incidence of complications such as equincisional infection, postoperative anastomotic fistula, abdominal hemorrhage and subcutaneous emphysema in experimental group was significantly lower than that in control group, with statistical significance (P<0.05). The recurrence rate of 5 months after operation in experimental group was significantly lower than that in control group, with statistical significance (P<0.05). Conclusion: Laparoscopic pull-out surgery for colorectal eversion has the advantages of small trauma. And it can significantly reduce the recurrence rate and the incidence of complications and shorten the length of hospital stay. It has the value of promotion.
