Abstract: Objective To compare the safety and feasibility of transumbilical single-hole+1-hole laparoscopy and traditional laparoscopic radical resection of colorectal cancer. Methods Data of 42 patients with colorectal cancer admitted to our hospital from October 2018 to May 2021 were collected. Patients were divided into the study group and the control group according to different surgical methods, and 21 patients in each group. The two groups were treated with umbilical single-hole+ 1-hole laparoscopic radical mastectomy and traditional laparoscopic radical mastectomy. Data of operation time, intraoperative blood loss, postoperative exhaust time, postoperative hospital stay, number of lymph node dissection and postoperative complications were compared between the two groups. Results The postoperative hospitalization time was significantly shorter in the study group than that of the control group (P＜0.05). There were no significant differences in the operative time, intraoperative blood loss, postoperative exhaust time and number of lymph node dissection between the two groups (P＞ 0.05). There was no anastomotic fistula in the two groups after operation. There were one case of intestinal obstruction, one case of anastomotic bleeding and two cases of incision infection in the control group, and one case of anastomotic bleeding and one case of incision infection in the research group. There were no significant differences in the complications between the two groups (P＞0.05). Conclusion Transumbilical single-hole+1-hole laparoscopic radical resection of colorectal cancer is safe and feasible, and which is superior to traditional endoscopic surgery in postoperative recovery.
