title: [Redo surgery in Hirschsprung's disease for postoperative distension and constipation].
abstract: OBJECTIVE
  To summarize the reason and treatment of redo surgery in Hirschsprung disease for postoperative distension and constipation.
  
  
  METHODS
  From January to December 2014, 35 patients with constipation and distention after pull-through done elsewhere were referred to our institution. The reasons procedures and outcomes of redo surgery were a retrospectively analyzed.
  
  
  RESULTS
  The indication of reoperation in 21 cases was pathological problems, including residual aganglionosis, retained transition zone bowel, and in 13 cases was anatomical problems, including retained dilated segment, obstructive Soave cuff. One case had both pathological and anatomical problems. Among them, 5 cases belonged to total colonic aganglionosis. All the cases received conservative treatment for about 6 months before reoperation. Five cases had enterostomy before redo pull through surgery. Thirty cases underwent Soave surgery with or without laparoscopy or laparotomy. Twenty-six cases underwent transabdominal Soave surgery, 3 cases transanal Soave surgery, 1 case transanal Soave surgery with laparoscopy. Other surgery included Ikeda surgery, excision of diaphragm or scar, and anoplasty. Postoperative complications were found in 3 patients. One had rectovesical fistula and was cured after operation. Two cases had anastomotic leakage and then underwent diverting ileostomy. Thirty-three cases had a mean follow-up of 59 months. During the follow-up, 32 cases had no distension and constipation. Two cases presented occasional dirty pants, 2 cases frequent soiling, 1 case daily soiling.
  
  
  CONCLUSIONS
  Reasons of distension and constipation in Hirschsprung's disease after surgery are pathological and anatomical problems. Operation procedure is chosen based on reasons. Transabdominal Soave surgery is safe and effective.
