Study Summary

Patients undergoing routine rectal suction biopsy will undergo as part of the study an additional Endoscopic mucosal resection. The biopsy results will also be correlated with patient's clinical data including clinical history, Bristol stool scale, anorectal manometry results, and SITZ marker studies. Cost and recovery time will be compared.

Primary Outcome

The adequacy of the tissue specimen, the proportion of diagnostic specimens, and the proportion of patients that would have required subsequent referral for full thickness biopsy, will be compared. Variable such as cost and recovery time will be compared. Biopsy results will be compared with patient's pre-endoscopy clinical data including their history of constipation, results of SITZ marker studies, Bristol stool scale, and anorectal manometry.
