We reported the six cases of laparoscopic ovarian metastasectomy for gastric cancer during IP and intravenous paclitaxel plus S-1 therapy. The median patient age was 40.5 years, and ovarian metastases were metachronous in five cases. All six surgeries were completed successfully without complications, adhesions, or conversion to open surgery.

Four patients died from cancer, with a median postoperative survival of 18.5 months, excluding two patients who remained alive. Laparoscopic ovarian metastasectomy was feasible when peritoneal dissemination was well controlled by IP paclitaxel, and there were no strong adhesions around the ovarian metastases, which were presumed to have spread via lymphatic or hematogenous routes. Furthermore, ovarian metastasectomy reduced postoperative ascites formation, and the minimally invasive approach enabled the early resumption of IP paclitaxel therapy after a short treatment suspension.
