Abstract:
A reliable and simple method of allograft fixation in laparoscopic posterior-loop rectopexy (LPR) was developed. The study was carried out on 40 cadavers, peak effort of separation of the net fixed to the sacrum by various methods was evaluated. Effort of separation in fixation of the net by sutures was 10.1 +/- 2.12 kg, in fixation by hernial stapler--1.13 +/- 0.36 kg, stapler "Pro-Tack"--6.38 +/- 1.85 kg, in fixation of the net by the new device--8.9 +/- 0.75 kg. From 1995 till 1999 LPR was performed with the new device in 15 patients, the open posterior-loop rectopexy (OPR) with fixation of the net by non-absorbable sutures--in 16 patients. In LPR intraoperative blood flow was twice as small (146.0 +/- 79.2 ml) as in OPR (275.6 +/- 76.9 ml). Mean time of LPR was 183.1 +/- 69.8 min, OPR--211.3 +/- 57.9 min. Relief of pain after LPR enabled with reduction of narcotic analgetics requirement (58.3 +/- 1.5 mg). Mean dose of narcotic analgetics after OPR was 93.2 +/- 1.4 mg. The proposed method of allograft fixation and device for it realization are effective and meet all requirements.
