Gastric cancer is commonly treated via minimally invasive surgery. The present study explored the feasibility of right-side approach-duet (R-duet) totally laparoscopic distal gastrectomy using a three-port compared with a four- or five-port.


A total of 251 patients who underwent curative totally laparoscopic distal gastrectomy for gastric cancer (72 R-duet, 74 four-port, and 105 five-port) at the Catholic Medical Center were enrolled. All operations were performed using conventional laparoscopic instruments. The clinicopathological characteristics, operative details, and postoperative short-term outcomes were analyzed retrospectively.


The clinicopathological characteristics did not differ significantly among the groups, except that the N stage was higher in the five-port group. The operating time was significantly longer in the four-port than the R-duet group (R-duet, four-port, and five-port 148.2 ± 30.7, 162.4 ± 30.6, and 159.9 ± 31.5 min, respectively; p = 0.024). The estimated blood loss did not differ significantly. Postoperatively, the times to flatus and to soft diet consumption and the hospital stay were significantly longer in the five-port group. The extent of postoperative complications did not differ among the groups.


R-duet totally laparoscopic distal gastrectomy is a reliable form of reduced-port surgery when used to treat gastric cancer; no special instruments are required.
