BackgroundThe purpose of this study was to show the feasibility and safety of pure single-port laparoscopic distal gastrectomy (SDG) by comparing its short-term outcomes with those of conventional multiport totally laparoscopic distal gastrectomy (TLDG).Study DesignProspectively collected data of 50 gastric cancer patients who underwent pure SDG from November 2011 through October 2013 were compared with the matched data of 50 TLDG patients.ResultsMean operation time (144.5 vs 140.3 minutes; p = 0.561) and number of harvested lymph nodes (51.7 ± 16.3 vs 52.4 ± 17.9; p = 0.836) were comparable. Estimated blood loss was lower in the SDG patients (50.5 ± 31.5 mL vs 87.5 ± 79.6 mL; p = 0.007). Postoperative recovery was faster in the SDG patients in terms of lower maximum pain score on the operative day (6.1 ± 1.4 vs 6.9 ± 1.5; p = 0.015) and postoperative day 1 (4.6 ± 1.0 vs 5.5 ± 1.4; p < 0.001), less use of parenteral analgesics (0.8 ± 1.0 vs 1.4 ± 1.0; p = 0.020), and less increase in C-reactive protein level on postoperative day 5 (4.57 ± 6.26 mg/L vs 8.51 ± 5.25 mg/L; p = 0.008). Postoperative morbidity occurred in 6 (12%) and 5 (10%) patients in the SDG and TLDG group, respectively.ConclusionsThis study showed that pure SDG is both safe and feasible for early gastric cancer, with similar operation time and better short-term outcomes than TLDG in terms of postoperative pain, estimated blood loss, inflammatory reaction, and cosmetic result.Copyright © 2014 American College of Surgeons.
