Official Title: Efficacy and Accuracy of a New Diagnostic Scoring System to Differentiate Hirschsprung Disease From Hirschsprung Disease Allied Disorders in t

Brief Summary:

  1. The investigators previously reported a simple diagnostic scoring system to differentiate Hirschsprung disease (HD) from Hirschsprung disease allied disorders (HAD) in the patients with suspected intestinal dysganglionosis. In the retrospective study, the investigators concluded that the patients with a predicting score of more than 5 are more likely to be diagnosed with HD, whereas a score less than 5 is mostly indicative of HAD.
  2. Since it is essential to confirm the accuracy and efficacy of the scoring system in a prospective manner before it is used as a standard procedure, this prospective study is designed and performed.

Detailed Summary:

  1. Patients have hard or firm stools for 2 or less per week, and with ages from newborn to 3 years old are recruited in this study.
  2. The recruited patients is undergoing preoperative work-up including barium enema (BE), anorectal manometry (ARM) and histochemical acetylcholinesterase (AChE) staining of rectal mucosa. Known risk factors for intestinal dysganglionosis (IDs) are recorded. The predicting score is calculated by summing the scores of the risk factors and 3 preoperative tests.
  3. The patients with a predicting score of more than 5 are diagnosed with HD, and are performed surgery to remove the aganglionic bowel.
  4. The patients with a score less than 5 are mostly indicative of HAD, and receive conservative therapies that included colonic irrigation, enema, high dose lactulose, and oral paraffin oil for at least 6 months. When there is no clinical improvement, patients are consented for surgical procedures to remove the dysganglionic bowel segments.

Current Primary Outcome: the predicting score calculation [ Time Frame: 6-12 months ]

The recruited patients is undergoing preoperative work-up including barium enema (BE), anorectal manometry (ARM) and histochemical acetylcholinesterase (AChE) staining of rectal mucosa. Known risk factors for IDs are recorded. The predicting score is calculated by summing the scores of the risk factors and 3 preoperative tests.

The patients with a predicting score of more than 5 are diagnosed with HD, and are performed surgery to remove the aganglionic bowel.

The patients with a score less than 5 are mostly indicative of HAD, and receive conservative therapies that included colonic irrigation, enema, high dose lactulose, and oral paraffin oil for at least 6 months. When there is no clinical improvement, patients are consented for surgical procedures to remove the dysganglionic bowel segments.



Original Primary Outcome: Same as current

Current Secondary Outcome: pathological diagnosis [ Time Frame: 12-18 months ]

The intestinal specimens were reviewed by 3 experienced pathologists all of whom had participated in a consensus meeting on diagnostic criteria of IDs.


Original Secondary Outcome: Same as current
