Small bowel and colorectal muscle biopsies require a surgical approach. Advancing our understanding of the pathophysiology of motility disorders, such as functional bowel disorders, intestinal pseudo-obstruction and slow transit constipation, is hindered by our inability to non-invasively obtain muscularis propria (MP) for evaluation of multiple cell types, including myenteric neurons. The aims of this study were to determine (1) technical feasibility, reproducibility and safety of performing duodenal endoscopic muscle biopsy (dEMB) and rectal endoscopic muscle biopsy (rEMB) using a clip-assist technique; and (2) presence of myenteric neurons in tissue samples.
