Abstract: Objective:To explore the clinical efficacy of singleport 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 singleport Da Vinci robotic surgical system, and intraoperatively received laparoscopyassisted digestive tract reconstruction. Observation indicators: (1) intra and postoperative situations; (2) followup and survival. Followup using outpatient examination and telephone interview was performed to detect patients′ survival up to July 2017.
Results: (1) Intra and postoperative situations: the patient underwent successful singleport Da Vinci robotic radical resection of rectal cancer. The operation time and volume of intraoperative blood loss were 145 minutes and 20 mL, without blood transfusion. The using time of nonsteroidal analgesic drug, time for outofbed activity, time to anal exsufflation, time of fluid diet intake and time of pelvic drainage tube removal were 1 day, 24 hours, 48 hours, 72 hours and 4 days after operation, respectively. No postoperative complication was detected. Results of postoperative pathological examination: moderatedifferentiated 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) Followup and survival: the patient was followed up for 1 month, with a good survival.
Conclusion:Singleport Da Vinci robotic surgical system in the radical resection of rectal cancer is safe and feasible, with good short-term outcomes.
