Methods: From March 2021 to March 2022, eight low rectal cancer patients underwent SILS + 1 laparoscopic assisted taTME in our hospital. Results: All 8 patients received (SILS + 1) laparoscopic-assisted taTME and sigmoid-anal anastomosis. Of the 8 patients, 6 were male and 2 female;mean age was (62.3 ± 14.1) years old;body mass index was (23.8 ± 2.7) kg/m2;distance from tumor to anal edge was (31.5 ± 10.7) mm;diameter of tumor was (43.9 ± 7.8) mm. All the patients were successfully completed without conversion to laparotomy perioperative, with no accidental injury and severe complications in the operation. The mean total operative time was (223.1 ± 61.5) minutes;abdominal operation time was (150.5 ± 36.4) min, time of taTME was (80.1 ± 22.5) minutes, intra-operative blood loss was (28.8 ± 13.6) mL, the distance from anastomotic stoma to dentate line was (9.4 ± 7.3) mm. The length of the specimens was (155.0 ± 80.9) mm;all the mesorectum was complete, the mean number of lymph nodes dissected was (18.1 ± 7.6), The mean distal margin was (19.4 ± 3.2) mm, and the proximal, distal and circumferential margins were all negative. All patients start drinking water on the first day, and have fluid diet on the second day after operation. The drainage tube was removed 7 to 9 days after surgery. The postoperative hospital stay was 8 to 15 days. The second case developed urinary retention on the third day after the operation, and healed after 30 days by indwelling catheterization and oralling “Pyridostigmine Bromide Tablets”. The sixth patient developed grade B anastomotic leakage on the 8th day after operation, and was healed after conservative treatment such as local irrigation and drainage, anti-infection, and anal sitz bath. All the patients were followed up for 24 to 36 months, and no tumor recurrence transfer and death cases were observed. Conclusion: The method of SILS + 1 laparoscopy-assisted taTME has a good short-term curative effect in the treatment of low rectal cancer. While reducing the difficulty of single-port laparoscopic operation, it can give full play to the advantages of taTME, and has both cosmetic effects.展开更多
