Comparison of efficacy between natural orifice specimen extraction without abdominal incision and conventional laparoscopic surgery in the treatment of sigmoid colon cancer and upper rectal cancer.
2019
PURPOSE: To compare the short-term efficacy between natural orifice specimen extraction (NOSE) without abdominal incision and conventional laparoscopic surgery in the treatment of sigmoid colon cancer and upper rectal cancer. METHODS: A total of 86 patients scheduled to undergo laparoscope-assisted radical surgery of sigmoid cancer or upper rectal cancer from January 2015 to September 2017 (T1-3 stages in preoperative imaging evaluation, no distant metastasis, and body mass index 0.05). The postoperative tumor recurrence rate had no significant difference between the two groups (p=0.359), and the Log-rank test revealed that the disease-free survival (DFS) rate had no statistically significant difference between the two groups (p=0.280). CONCLUSIONS: NOSE without abdominal incision has a comparable short-term clinical efficacy to conventional laparoscopic surgery in the treatment of sigmoid cancer and upper rectal cancer, but it significantly reduces the amount of intraoperative bleeding and lowers the pain of patients, with rapid postoperative recovery and high safety, so it is worthy of clinical popularization.
