Through introduce the clinical experience of Da Vinci robot combined with prone jackknife position for abdominoperineal resection of rectal cancer(miles operation), determine its safety and feasibility.

Fifteen patients who underwent abdominoperineal resection of rectal cancer in department of general surgery, Nanjing General Hospital of PLA from Jan. 2015 to Jul. 2016, were enrolled in this study . Their clinical data were retrospectively analyzed to assess the feasibility and safety of this novel surgical method.

15 patients were successfully completed the operation, the operation time was 150-190 min[mean (164.5 ± 20.4)min]; the intraoperative blood loss was 20-50 ml[mean (28.5 ± 9.4)m1]; the number of lymph nodes harvested was 10-18 per case (mean 14.7 ± 3.7); the colostomy exhaust time was 4-40 h [mean (18.4 ± 10.7)h]; the micturition time for the first time was 6-32 h [mean (13.3 ± 6.7)h]; the postoperative hospital stay were 4-16 d (6.6 ± 3.1)d . The patients were followed up for 4-8 weeks, no serious complications, no tumor recurrence and death.

Robot combined with prone jackknife position for abdominoperineal resection of rectal cancer is safe and feasible, with less bleeding, less bleeding in the perineal incision, less seepage volume of perineal incision, less complications, faster recovery, shorter hospital stay and other advantages.
