Abstract:
Objective This study is a comparison of the clinical effect of the B-ⅰ method of natural NOSES versus laparoscopic intersphincter resection（ISR）in low rectal cancer.
Methods A total of 100 patients diagnosed with low rectal cancer between June 2017 and June 2021 were prospectously assigned to two groups with 50 patients in each group using a random number table method. The NOSES group receives the Tnoses Ⅰ B method and the ISR group receives the ISR. Perioperative indexes，postoperative complications and anorectal function were compared between the two groups. Statistical software SPSS 20.0 was used to complete the data analysis，and the statistical data such as postoperative complications and Kirwan grading were compared between groups by x2 test. Measurement data such as perioperative indicators and Wexner score were represented by（
±
s）. Comparison between groups was performed by t test.
P<0.05 was considered statistically significant.
Results NOSES group has shorter operating time，first exhaust time，and postoperative hospital stay than ISR group（P<0.05）；There was no significant difference in the total incidence of postoperative complications between the two groups（P>0.05）. The Wexner score of the NOSES group was significantly lower than that of the ISR group 6 months and 12 months after surgery（P=0.000）；NOSES group Kirwan grading is superior to ISR group（P=0.029）.
Conclusion This NOSES Ⅰ type B therapy in patients with low rectal cancer has shorter operation time and less intraoperative bleeding than ISR，which effectively protects patients' rectal and anal function and is more beneficial to postoperative recovery.
