摘要：Abstract This phase II clinical trial was performed to determine whether reduced-port laparoscopic surgery with complete D2 lymph node (LN) dissection for gastric cancer is a safe and feasible surgical technique. The prospectively enrolled 65 gastric cancer patients underwent reduced-port surgery (i.e., triple-incision totally laparoscopic distal gastrectomy [Duet TLDG] with D2 lymphadenectomy). Compliance rate was the primary outcome, which was defined as cases in which there was no more than one missing LN station during D2 LN dissection. The secondary outcomes were the numbers of dissected and retrieved LNs in each station and other short-term surgical outcomes and postoperative course. The compliance rate was 58.5%. The total number of retrieved LNs was 41 (range: 14–83 LNs). The most common station missing from LN retrieval was station no. 5 (35/65; 53.8%), followed by station no. 1 (24/65; 36.9%). The overall postoperative complication rate was 20.0% (13/65). One patient underwent surgical treatment for postoperative complications. There was no instances of mortality. Duet TLDG is an oncologically and technically safe surgical method of gastrectomy and D2 lymphadenectomy.
