Abstract:

Objective To investigate the safety and feasibility of transanal natural orifice specimen extraction surgery (NOSES) laparoscopic surgery for sigmoid colon cancer and high rectal cancer. Method A retrospective analysis of clinical datas of 30 patients who underwent transanal NOSES laparoscopic surgery for sigmoid colon cancer and high rectal cancer(the observation group) and 30 patients who underwent conventional laparoscopic surgery for sigmoid colon cancer and high rectal cancer(the control group) during the same period, in Putian City from October 2018 to October 2020. A comparative analysis was conducted between these two groups in regard to the operation time, the intraoperative blood loss, the intraoperative lymph node dissection, the postoperative pain score of day 1, the postoperative complications and the postoperative local recurrence and distant metastasis. Result There were no significant differences in the intraoperative blood loss, the intraoperative lymph node dissection and the postoperative complications of both groups (P ＞ 0.05). The operation time of the observation group was longer than that of the control group, the postoperative pain score of day 1 of the observation group was lower than that in the observation group, the postoperative exhaust time of the observation group was shorter than that in the control group, the postoperative fluid diet time in observation group was shorter than that in control group, the postoperative hospital stay in the observation group was shorter than that in the control group, the differences are significant (P ＜ 0.05). Patients in both groups were followed up and no local and distant recurrence was observed.Conclusion Transanal NOSES laparoscopic surgery for sigmoid colon cancer and upper rectal cancer is safe and feasible. It has the advantages of light postoperative pain, quick recovery, short hospital stays, and the radical tumor treatment effect is comparable to that of traditional laparoscopic surgery.
