title: [Reoperation for postoperative constipation recurrences of Hirschsprung disease].
abstract: OBJECTIVE
  To summarize the causes and treatment experiences of postoperative constipation recurrences of Hirschsprung disease.
  
  
  METHODS
  Clinical data of 37 cases receiving operation again for postoperative constipation recurrences of Hirschsprung disease were collected. The recurrent causes, reoperation procedures and therapeutic efficacy were analyzed.
  
  
  RESULTS
  Among 37 cases, the recurrent causes included insufficient resection of the intestine in 14 cases, co-existent intestinal neural hypogenesis in 6, gate syndrome in 5, and others in 12 cases. There was no postoperative death. Thirty-one cases (83.8%) were followed-up from 6 months to 11 years. The defecation frequency was 1-2 times per day in 15 cases, one times per two days in 7, one times per three days in 6 cases. Two cases could defecate with the help of laxative purgatives. Nobody had incontinence.
  
  
  CONCLUSIONS
  The main cause of postoperative constipation recurrences of Hirschsprung disease is insufficient resection of the intestine,and reoperation can get better results.
