Diagnosis and Treatment of Diffuse Cavernous Hemangioma of the Rectum: Report of 17 Cases

Abstract

DCHR is often misdiagnosed. Preoperative colonoscopy and MRI are essential in making the correct diagnosis and to depict the extent of the lesion accurately. Due to its origination from the dentate line and the involvement of the whole layer of the rectal wall and the rectal mesentery, the treatment of choice for DCHR is complete resection by the pull-through transection and coloanal anastomosis.
