Bowel dysfunction has been proven as the most common complication after pull-through(PT) of Hirschsprung disease(HD) ，which may persist to adulthood and lead to social problems.The reason of bowel dysfunction is complicated and the risk factors were not defined.

Hirschsprung disease (HD) is a distinctive congenital disease with the absence of ganglion cells in the distal intestine leads to distal bowel obstruction and defecation disorders. HD is a rare disease, with a reported incidence of 1:5,000, requiring proper surgical treatment for the maintenance of normal or near-normal bowel movement.To date, there is insufficient evidence to recommend a preferred or superior method for the surgical repair, and a pull-through with or without laparoscopy was the most common procedure for correction of HD,which may have faster recovery and less rate of complication compared to other surgical approaches.The short or long-term outcomes of HD have been deeply assessed in the past few years,and bowel dysfunction,consist of soling, incontinence and constipation, had been proven as the most common complication,which may be a ongoing issue and lead to social problems,which should not be ignored. Otherwise,there were many reports proved that poor bowel function in preschool and early childhood may lead to social problems and depression in adolescence or adult.Many factors may lead to bowel dysfunction in HD, including length of aganglionic segement,anastomotic leakage or redo-PT,unsuitable timing of surgery,etc.Thus,the present study was designed to seek the risk factors for bowel dysfunction of HD,which is meaningful to maintain or improve the bowel function in preschool and early childhood.
