OBJECTIVE Infected pelvic hematoma is a serious complication of hysterectomies. Pelvic drainage can help reduce complications. In this study, we evaluated the efficacy and safety of vaginal vault drainage in patients who underwent laparoscopic hysterectomy for benign gynecological diseases. METHODS Patients who underwent laparoscopic hysterectomy and pelvic drain insertion for benign gynecological diseases between January 2008 and December 2015 were enrolled retrospectively in the study. They were grouped according to drain insertion sites, that is, through the abdomen (group 1) and vaginal vault (group 2). The postoperative outcomes were compared between the two groups. RESULTS A total of 504 women were included. No significant differences were observed in the prevalence of postoperative fever, readmission, and reoperation between the two groups. CONCLUSIONS Given the discomfort associated with holding and removing the abdominal drain, inserting a closed pelvic gravity drain through the vaginal vault appears to be a feasible alternative to an abdominal drain.
