Résultats à moyen terme du traitement par voie vaginale du prolapsus génital de grade 3 et 4 par hamac total de derme porcin associé à une sacro-spinofixation bilatérale

Abstract

To evaluate the feasibility, morbidity and mid-term results of genital prolapse cure by vaginal route using a total hammock of porcine skin implant (Pelvicol) and bilateral sacro-spinofixation. From May 2001 to June 2006, 101 patients with grade 3-4 genital prolapse, using the POPQ classification, were treated by vaginal route. One patient refused the use of porcine skin implant for religious reasons. Anterior fixation of the total hammock was performed by transobturator route and the posterior fixation was done on sacrospinous ligaments associated with a bilateral Richter operation. Intra- and postoperative complications, anatomical results, as well as global satisfaction, have been evaluated. The technique was always feasible. With a mean follow-up of 29 months, anatomical results were optimal in 73.3% while 16.8% of recurrences were observed. Mean operating time was 112+/-39 min (range: 40-310). Intraoperative complication rate was 4.9% (three bladder injuries, one rectal injury, one unfundibulo pelvic ligament injury during hysterectomy). Postoperative complication rate was 11.9% (four cases of urinary retention, one urethral plication and five pararectal haematomas including two cases requiring a second surgery complicated by an urethrovaginal fistula in one case and one urinary infection). With a mean follow-up of 29+/-12 months (74-12), optimal anatomical results and recurrence rate were 73.3 and 16.8%, respectively. Global satisfaction rate was 87.7%. This rate decreased to 60% for patients with a 4- to 6-year follow-up. Our results confirmed the feasibility of genital prolapse cure using a total hammock of porcine skin and bilateral sacro-spinofixation with a similar rate of complications to vaginal surgery without implant. However, anatomical results at mid-term raise the issue on the permanence of biological meshes.
