title: Modified H-pouch as an alternative to the J-pouch for anorectal reconstruction.
abstract: OBJECTIVE
  A modification is described of the J-pouch to facilitate ileoanal anastomosis in the presence of an anal or anovaginal fistula.
  
  
  METHODS
  The bowel is divided at the level of the apex of the J-pouch, the distal limb is advanced to project beyond the proximal limb by 3-5 cm. The pouch is constructed by a side-to-side anastomosis to form the H-pouch with a distal ileal segment, which is passed through the anal canal to form an ileoanal anastomosis.
  
  
  RESULTS
  The modification allows the treatment of anal and rectal disorders not resolvable by a usual J-pouch construction, as in cases where a rectal resection is needed for concomitant fistulation or destruction of the anal mucosa. The functional results are similar to those of the J-pouch, with no added postoperative morbidity. This technique helps to avoid permanent stoma in selected cases.
  
  
  CONCLUSIONS
  The modified pouch is relatively simple to perform and can help the surgeon to address complex anorectal disorders.
