An Unusual Cause of Rectal Bleeding -Report of Three Cases and Literature Review

Abstract

Haemangioma of the rectum and colon is very rare malformation with only around 100 cases have been reported so far. Most commonly young adult is affected. Common site is recto sigmoid junction. Here we present three cases of rectal haemangioma affecting two males and one female patient. All were having cavernous type of haemangioma at rectum and recto sigmoid junction with one involving additional caecum and ascending colon. All the cases were misdiagnosed previously. Colonoscopy is the cornerstone for evaluation of these patients showing bluish discoloration with engorged mucosa. Rectum and sigmoid colon are commonly affected. Abdominoperineal resection was the favored procedure in the past. At present, definitive treatment of diffuse cavernous haemangioma (DCH) of rectum and sigmoid colon is excision of the involved bowel with sphincter saving procedure with either stapling or hand sewn anastomosis of colon and anal canal.

Key words: Rectal haemangioma; sphincter saving surgery.
