Initial Experience of Dual-Port Laparoscopic Distal Gastrectomy for Gastric Cancer: A Single-Arm Study.

Abstract

Dual-port laparoscopic gastrectomy (DPLG) has been widely performed in recent years for treating gastric cancers. The present study reports our initial experience of dual-port laparoscopic distal gastrectomy (DPLDG). From November 2016 to August 2018, 38 consecutive patients underwent DPLDG in our center. The observational outcomes included 30-day morbidity and mortality rates, time to first flatus, time to first oral liquid diet, time to first oral semiliquid diet, time to drainage tube removal, visual analogue scale (VAS) score, postoperative 4-day recovery rate, additional analgesic use, hospital stay and cosmetic benefits. Mean operative time was 191.6 ± 44.4min, mean intra-operative blood loss was 39.8 ± 48.7ml, and the mean number of dissected lymph nodes was 38.3 ± 13.7 nodes. One case was converted to five-port laparoscopic surgery, and no intraoperative complications occurred in any of the cases. The mean time to postoperative first flatus was 45.3 ± 18.0h. The mean time to intake of an oral liquid diet was 56.7 ± 30.4h. The mean time to drainage tube removal was 97.9 ± 52.3h. The mean VAS scores for the 3days after surgery were 2.3 ± 0.7, 2.0 ± 0.6 and 1.6 ± 0.5, respectively. A total of 81.6% of the enrolled patients met the postoperative 4-day recovery standard, and 15.8% of patients received additional analgesics. The mean postoperative hospital stay was 6.0 ± 2.0days. No deaths were observed, and the 30-day morbidity rate was 13.2%. DPLDG is a feasible and safe procedure for experienced surgeons with acceptable short-term outcomes, reduced invasiveness and good cosmetic effects.
