ABSTRACT

Objective To explore the clinical efficacy of single-port Da Vinci robotic surgical system in the radical gastrectomy of gastric cancer.Methods The retrospective descriptive study was conducted.The clinical data of the first patient in China who underwent single-port radical gastrectomy of gastric cancer using Da Vinci robotic surgical system in the Southwest Hospital of the Third Military Medical University in June 2017 were collected.Patient underwent radical gastrectomy of gastric cancer using single-port Da Vinci robotic surgical system +D2 lymph node dissection + Billroth Ⅱ anastomosis.Observation indicators(1) intra-and post-operative situations;(2) follow-up and patients' survival.Follow-up using outpatient examination and telephone interview was performed to detect the patients' postoperative survival up to July 2017.Results (1) Intra-and postoperative situationspatient underwent radical distal subtotal gastrectomy of gastric cancer using single-port Da Vinci robotic surgical system.Operation time and volume of intraoperative blood loss were respectively 303 minutes and 100 mL.There was no intraoperative complication.The distances from tumor to proximal margin and distal margin were 5 cm and 6 cm.Number of lymph node dissected and length of abdominal incision were 51 and 3 cm.Time of gastric tube removal,time for out-of-bed activity,time of gastrointestinal function recovery,time of drainage tube removal and postoperative pain score were 17 hours,24 hours,36 hours,36 hours and 3,respectively.Patient took a little fluid diet after gastric tube removal.There was no occurrence of postoperative complication.Results of pathological examination showed that tumor invaded deep muscular layer,with 2 positive lymph nodes in No.3 and negative proximal and distal margins.Pathological staging was pT2N1M0 (Ⅱa staging).Duration of hospital stay was 6 days.(2) Follow-up and patients' survivalpatient was followed up for 1 month,with a good survival.Conclusion The single-port Da Vinci robotic surgical system is safe and feasible in the radical gastrectomy of gastric cancer,with good short-term outcomes.
