<bold>The aim of the study</bold> was to present and compare own results of abdominal rectopexy performed with absorbable and nonabsorbable materials used in surgical repair of rectal prolapse.
<bold>Material and methods.</bold> In the years 1991-2009, 50 patients were operated on for rectal prolapse. The first 8 patients (group I) were operated using absorbale polyglycolic acid mesh. The next 42 patients were operated using non-absorbable polypropylene mesh (group II). 12 patients with chronic, incurable constipation had sigmoidectomy and rectopexy performed at the same operation. Rectopexy was performed with the mesh and fixed to the pelvic fascia and periosteum and mesorectum, leaving the anterior one third of the rectum free. 6 months after surgery functional outcomes were evaluated. Statistic analysis with the level of statistical significance p<0,005 was applied to obtained functional results.
<bold>Results.</bold> On the follow up visits, there were no symptoms of the recurrence of rectal prolapse in 5 patients (62.5%) from group I and in 25 patients (92.6%) from group II. Patients relapsing were reoperated 24 to 98 months after primary surgery. In all patients from group I (absorbable mesh), prosthetic material was not found at reoperation. In redo surgery only non-absorbable mesh was used.
<bold>Conclusions.</bold> The effectiveness of rectal fixation depends on the on the durability of the prosthetic material. In the studied group polypropylene mesh was superior in rectopexy to absorbable mesh.
