[The use of a new plastic method for consolidating a preternatural anus as prevention in paracolostomy hernias].

Once the stage of extraperitoneal evasion of the sigmoid has been achieved for definitive preternatural anus, transsection is made of the aponeurosis of m. obliqu. ext. abdominis along its tendon fibers at a length of 5-6 cm. Then an aperture is made along the muscle fibers with the same length on m. obliqu. int. abdominis and m. transversus abdominis as well and finally f. transversalis is transsected. The peritoneum is intra-abdominally detached from the fascia beneath and alongside the aperture. An "Ampoxen" layer is placed around the internal aperture of the abdominal wall. The explant is sutured to the fascia and the evaded sigmoid. The latter is sutured to the aponeurosis of m. obliqu. ext. abdominis. Another Ampoxen layer is placed over this aponeurosis and sutured to the evaded intestine and in a chess-board way to the fascia. The method was applied in 22 patients with very good postoperative result.
