ABSTRACT

Objective To explore the clinical efficacy of single-port Da Vinci robotic surgical system in the radical resection of rectal cancer.Methods The retrospective descriptive study was conducted.The clinical data of one patient with rectal cancer who was admitted to the Southwest Hospital of the Third Military Medical University in June 2017 was collected.The patient underwent the first case of radical resection of rectal cancer with the single-port la Vinci robotic surgical system,and intraoperatively received laparoscopy-assisted digestive tract reconstruction.Observation indicators:(1) intra-and post-operative situations;(2) follow-up and survival.Follow-up using outpatient examination and telephone interview was performed to detect patients' survival up to July 2017.Results (1) Intra-and post-operative situations:the patient underwent successful single-port Da Vinci robotic radical resection of rectal cancer.The operation time and volume of intraoperative blood loss were 145minutes and 20 mL,without blood transfusion.The using time of nonsteroidal analgesic drug,time for out-of-bed activity,time to anal exsufflation,time of fluid diet intake and time of pelvic drainage tube removal were 1 day,24hours,48 hours,72 hours and 4 days after operation,respectively.No postoperative complication was detected.Results of postoperative pathological examination:moderate-differentiated rectal adenocarcinoma invaded serosal layer,with negative circumferential margin,negative distal margin of rectum and mesenteric lymph node metastasis (1 of 16 harvested lymph nodes was positive).Pathologic staging was T4aN1M0 (stage Ⅲb).The patient was discharged from hospital at postoperative day 6.(2) Follow-up and survival:the patient was followed up for 1month,with a good survival.Conclusion Single-port Da Vinci robotic surgical system in the radical resection of rectal cancer is safe and feasible,with good short-term outcomes.
