Objectives: Anatomical and functional results of a modified sacral perineocolporectopexy for extreme forms of complex pelvic organs prolapse. Material and methods: Between 2005 and 2010, 10 women aged 47-75 years were treated by abdomino-perineal implantation of polypropylene mesh for modified sacral perineocolporectopexy and subsequently followed-up. They were suffering from enterocele (9 pts), genital prolapse (8 pts), descending perineum (5 pts), rectal prolapse (4 pts), rectocele (3 pts). Five women were incontinent (mean Wexner: 9) and six had incomplete rectal evacuation. Defecography revealed enterocele III°(5 pts) and II°(4 pts). MR designed descending perineum in 5 pts (mean: 3,8cm). Results: Permanent reconstruction of the pelvic floor and remission of organs prolapse was achieved at 12-months follow-up in all except 1 patient. There were 2 small vaginal erosions of the mesh and 1 haematoma within the pelvic floor. Improvement at rectal emptying was found in 4 patients, feeling of pelvic heaviness in 6 patients, dyspareunia in 3 patients. Mean incontinence score decreased from 9 to 4. Conclusions: 1. Modified sacral perineocolporectopexy is effective in the treatment of complex pelvic floor anatomical defects and organ prolapse. 2. Improvements in rectal emptying, pelvic feeling of heaviness and dyspareunia have been achieved. 3. The implant tolerance was good and the complications rate was law.
