Brief Summary:
The purpose of this study is to compare the diagnostic yield with endoscopic mucosal resection (EMR) in hirschsprung's disease versus that of standard rectal suction biopsy. In order to compare EMR versus rectal suction biopsy, patients' diagnostic specimens will be analyzed by tissue size, the presence of submucosal tissue, and positive acteylcholinesterase staining. Additionally, the proportion of patients who would have required subsequent full thickness surgical biopsy with each technique will be compared. Biopsy results will be compared with clinical data including history, Bristol stool scale, anorectal manometry results and SITZ markers studies. Finally, the estimated costs that would have been incurred with each method will be evaluated.

Intervention Details:
  • Procedure: Endoscopic Mucosal Resection (EMR)
    EMR is a common procedure in gastroenterology. The technique involves placing a band around a piece of mucosa in the GI tract. The band and the tissue are then removed using a cautery snare. The technique can be used to obtain tissue for diagnostic purposes or to remove lesions for therapeutic purposes.

Outcome Measures

Primary Outcome Measures :
  1. The major goal of this study is to test the hypothesis that EMR will result in a higher proportion of diagnostic specimens than RSB in patients sent for rectal suction biopsy. [ Time Frame: April 2009 ]

Secondary Outcome Measures :
  1. Secondary outcome variables include the size of the specimen, the presence of ganglionic tissue, the presence of submucosal tissue, and the positivity of the acetylcholinesterase stain. [ Time Frame: April 2009 ]
