Isolated rectal diverticulum complicating with rectal prolapse and outlet obstruction: case report.

The occurrence of rectal diverticula is very rare, with only sporadic reports in the literature since 1911. Symptomatic rectal diverticula are encountered even less frequently. Treatments of these complicated events range from conservative treatments to major surgical interventions. We present a hitherto unreported occurrence of isolated rectal diverticulum complicated with rectal prolapse and outlet obstruction. Delorme's procedure resulted in subsidence of symptoms and resolution of the diverticulum. It provides a minimal invasive surgical technique to successfully address the reported malady.
