Laparoscopic Sacrohysteropexy for Pelvic Organ Prolapse and the Technique Used for Uterine Preservation: A Case Report

Pelvic organ prolapse (POP) is prevalent among middle-aged and older women, and its prevalence is expected to increase in Japan in the future. Laparoscopic surgery for POP is covered by insurance and is currently a minimally invasive procedure. There are multiple treatment approaches for the uterus, especially sacrohysteropexy, for patients who wish to preserve their uterus. This approach requires an understanding of its anatomical characteristics, including how the arm is threaded. However, specific techniques for uterine preservation have not yet been thoroughly investigated or reported. Here, we discuss the innovative operative techniques for uterine preservation and mesh application achieved by laparoscopic sacrohysteropexy performed at our hospital. A 34-year-old woman presented at our hospital with a uterine prolapse in the hope of undergoing laparoscopic sacrohysteropexy. The anterior vaginal wall was dissected, the mesh fixed, and the right and left intrauterine foramina next to the cervix were deployed and released. The anterior vaginal wall mesh penetrated the released mesentery and was integrated with the mesh of the posterior vaginal wall. It was fixed to the anterior aspect of the cape angle by using a subperitoneal tunnel. This surgical case is currently under follow-up, with no recurrence to date. We elaborate upon the ingenious insertion site of the port for the preservation of the uterus, the secure fixation of the mesh to the uterus, and the traction method. Unlike laparoscopic sacrocolpopexy and sacrocervicopexy, laparoscopic sacrohysteropexy necessitates at least the aforementioned techniques. At our institution, we perform sacrohysteropexy following the method outlined in this case. A more efficient technique is expected to emerge as larger-scale studies accumulate additional cases, ultimately leading to widespread acceptance and standardization of the approach.
