Synopsis: We retrospectively investigated lymphocele appeared after the surgery including lymphadenectomy for gynecologic cancers in Toyama University hospital between January 2012 and February 2021. In 115 patients, 20 (17.4%) cases had lymphoceles. The incidence rate of lymphocele was 12.8%, 22.9%, and 18.9% (cervical cancer, endometrial cancer, and ovarian cancer). Though there was no difference among the cancer types, there was a significant correlation between the incidence of lymphocele and the number of dissected paraaortic lymph nodes, but not other site lymph nodes. Four lymphocele cases (3.5%) needed therapeutic intervention. Two cases with local infection could be cured with antibacterial drug and drainage; meanwhile, lymphoceles in the other 2 cases were improved after lymphoscintigraphy. Case 1 was stage IIIC ovarian cancer, that appeared lymphocele postoperative day 38. Lymphoscintigraphy was performed postoperative day 87, and the lymphoceles were disappeared postoperative day 137. Case 2 was stage II endometrial cancer, that appeared lymphocele postoperative day 14. Lymphoscintigraphy was done postoperative day 35, and the lymphoceles disappeared after two weeks. These suggest that lymphoscintigraphy improves lymphocele induced by lymphadenectomy in gynecologic cancers.
