Rhomboid flap in proctologic reconstruction.

Abstract

The application of Limberg-type transposition flaps of rhomboid shape has been demonstrated to be one method of covering defects in the perianal area or the anal canal, after the extirpation of lesions that cannot be closed at first attempt because of defect size. This series includes five patients treated over a period of five years; a total of seven flaps were performed because there were contralateral lesions in two patients. The technique consists of extirpation of the lesion to create a rhomboid-shaped defect, which is then covered by a flap cut following the Limberg or Dufourmentel technique. Anoplasty techniques have been long established and advancement or rotation flaps are the most popular in proctologic surgery. Transposition flaps are useful because they are easy to remember and perform and have no serious postoperative complications.
