Abstract:
Objective To explore the short?term clinical efficacy of robotic radical resection for high rectal cancer with transvaginal specimen extraction. Methods A cohort study was carried out. The clinical data of consecutive patients with high rectal cancer who underwent robotic radical resection at the Department of General Surgery of The First Affiliated Hospital of Nanchang University from June 2017 to January 2018 were retrospectively analyzed. Inclusion criteria: (1) preoperative diagnosis of rectal cancer, and distance from tumor to anal margin≥10 cm undercolonoscopy; (2) T1?3 assessed by preoperative imaging examination, and no distant metastasis; (3) female, age≥50 years old, body mass index≤30 kg/m2;(4) without radiotherapy and chemotherapy before surgery; (5) implementation of robotic radical surgery for high rectal cancer. Fourteen female patients undergoing transvaginal removal of specimen without abdominal incision were included in the no incision group with age of (62.2±9.3) years old and distance from tumor to anal verge of (12.5±0.9) cm. As the match of 1:2, 28 simultaneous patients of high rectal cancer undergoing traditional robotic surgery (surgery interval <8 months) were enrolled to the control group, with age of (60.6±12.8) years old and distance from tumor to anal verge of (11.3±3.8) cm. Short?term efficacy and safty were compared between two groups. Follow?up ended in September 2018. Results There was no significant difference in baseline data between the two groups (all P>0.05). Compared with the control group, the no incision group had longer operation time [(149.6±15.6) minutes vs. (130.9±12.9) minutes, t=–4.135, P<0.001], shorter time to postoperative flatus [(40.9 ±2.6) hours vs. (51.9±2.9) hours, t=12.049, P<0.001], lower pain score on the operation day and the first day after surgery (using Changhaipainstick) [(3.1±0.4) points vs. (4.6±0.7) points, t=7.458, P<0.001; (2.5±0.3) points vs. (3.3±0.5) points, t=6.142, P<0.001], shorter time to ground activity [(15.6±2.0) hours vs. (24.3±2.5) hours, t=11.102, P=0.030], and shorter postoperative hospital stay [(6.1 ± 0.8) days vs. (7.2 ± 1.3) days, t=2.806,P=0.008], whose differences were statistically significant. There were no significant differences in intraoperative blood loss, proportion of postoperative analgesia patients, and complication within 30 days after surgery (all P>0.05). In the no incision group and the control group,the tumor size was (3.1±0.4) cm and (3.6±0.9) cm, the proximal margin distance was (9.1±1.5) cm and (9.8±1.5) cm, the distal margin distance was (4.3± 0.4) cm and (4.5 ± 0.4) cm, the number of harvested lymph node was 15.8 ± 2.4 and 15.2 ± 2.5, and the number of positive lymph node was 0.6 ± 1.3 and 1.1 ± 2.4, respectively, whose differences were not statistically significant (all P>0.05). The mean followed?up period was 10 months (7?14 months) in the no incision group, and 14 months (10?18 months) in the control group. No local recurrence and distant metastasis were found in both groups. Conclusion Robotic radical resection for high rectal cancer with transvaginal specimen extraction is safe and feasible with advantages of rapid postoperative recovery, less postoperative pain and short hospital stay.
