Tendon Descensus Repair (TENDER) – A prospective clinical feasibility study of tendon transplantation for pelvic organ prolapse repair

Abstract

ObjectiveTo show the feasibility of tendon transplantation for minimally invasive pectopexy in pelvic organ prolapse repair. Study designPatients with uterine or vaginal vault prolapse (POP-Q point C Stage 2–4) were offered laparoscopic pectopexy by means of autologous semitendinosus tendon transplantation. This paper presents a case series and describes the technique regarding the first 10 patients who underwent surgery.After preparing the vagina or cervix for laparoscopic pectopexy a tendon of the patient’s semitendinosus muscle was stripped and brought intraabdominally through the 10 mm trocar. The tendon was fixed between the cervix or vagina and to the pectineal ligaments on both sides of the pelvis. ResultsAll operations were performed successfully without complications. Vaginal examination demonstrated the intended elevation of the middle compartment. Mobility and power of the affected leg did not change. Recovery was fast, and discharge was possible between the second and third postoperative day. ConclusionOur approach demonstrates the feasibility and safety of a laparoscopic pectopexy with a semitendinosus autograft instead of a synthetic mesh. The experience from orthopedic surgery shows that a semitendinosus tendon autograft is long-lasting and stable. In addition, the morbidity on the operated leg is low.
