title: [Analysis of the relationship between stoma position and postoperative effects of procedure for prolapse and hemorrhoids in the treatment of hemorrhoids].
abstract: OBJECTIVE
  To explore the relationship between stoma position and postoperative effects of procedure for prolapse and hemorrhoids (PPH) in the treatment of hemorrhoids.
  
  
  METHODS
  Four hundred and one hemorrhoid patients were treated with circular stapler. II hemorrhoids, 45 cases; III-IV hemorrhoids, 356 cases. The position of stoma located 1 cm up dentate line, 219 cases; 1-2 cm up dentate line, 87 cases; 2-3 cm up dentate line, 60 cases; 3-4 cm up dentate line, 25 cases; > 4 cm up dentate line, 10 cases. The patients were followed from one week to two years postoperatively.
  
  
  RESULTS
  Postoperative effects and procidentia rates have significant association with the position of stoma. If the distance between position of stoma and dentate line is < or = 2 cm, the postoperative procidentia rate was 1.1%, lower than that of the distance > or = 4 cm.
  
  
  CONCLUSIONS
  The complication and procidentia rate of PPH is associated with the stoma position. The stoma position should be no more than 2 cm to dentate line.
