To investigate the feasibility and clinical efficacy of three-dimensional (3D) laparoscopic radical gastrectomy in patients with gastric cancer.

The clinical data of 21 patients who underwent 3D laparoscopic radical gastrectomy for gastric cancer at the Ruijin Hospital from December 2013 to November 2014 were retrospectively analyzed. The surgical indications and method of 3D laparoscopic radical gastrectomy were similar to that of two-dimensional laparoscopic radical gastrectomy. All the patients were followed up via outpatient examination and telephone interview till January 2015.

All the 21 patients underwent successfully laparoscopic surgery without conversion to open surgery, intraoperative complications and perioperative death. Eight patients underwent 3D laparoscopic radical gastrectomy (1 received concomitant cholecystectomy) and 13 underwent 3D laparoscopic-assisted radical gastrectomy (1 received concomitant cholecystectomy and 1 received concomitant radical resection of sigmoid colon). The mean operation time, mean volume of intraoperative blood loss, mean number of lymph node dissection, mean time to anal exsufflation and mean duration of hospital stay were 240 minutes (range, 180-300 minutes) , 100 mL (range, 10-180 mL) ,29 (range, 10-48 ) , 3 days (range, 1-4 days) and 9 days (range, 7-15 days) , respectively. Among the 21 patients, 1 patient was complicated with pulmonary infection and cured by conservative treatment, and no occurrence of complication was detected in the other patients. R₀ tumor resections in all the patients were done and the tumor resection margins were negative. Twenty-one patients were followed up for 2 -13 months with a median time of 7 months and without occurrence of surgery-related complications, tumor recurrence and death during the follow-up.

Three-dimensional laparoscopic radical gastrectomy is safe and feasible for the treatment of gastric cancer with the advantages of favorable short-term outcomes.
