Cloacogenic Polyps: An Unrecognized Cause of Rectal Bleeding
نویسندگان
چکیده
Cloacogenic inflammatory polyps correspond to a rare subtype of prolapsing mucosal polyps that arise around the anal transitional zone. It usually presents with rectal bleeding, tenesmus and altered bowel habits, and can mimic neoplasia. It is an unrecognized cause of hematochezia which may be overlooked at colonoscopy unless an endoscopic retroflexion maneuver is performed. Endoscopists should be aware of this entity. We present a case of rectal bleeding caused by an inflammatory cloacogenic polyp in a cirrhotic patient. To our knowledge, this represents the first report of this entity in a cirrhotic patient.

Inflammatory cloacogenic polyp: a rare cause of lower gastrointestinal bleeding.
Inflammatory cloacogenic polyp is a rare type of inflammatory anorectal lesion in which mucosal prolapse plays a pathogenetic role. It has been suggested that the aetiology may be the same as that of solitary rectal ulcer syndrome, inflammatory cap and myoglandular polyps (1,2). Inflammatory cloacogenic polyp can be associated with conditions such as Crohn’s disease, malabsorption syndromes, di...

Background: We report two rare cases of inflammatory cloacogenic polyps of the anorectum. The first case involves a 50 year old white female who presented with chronic diarrhea, prolapse, and rectal bleeding. The second case presents a 67 year old white male who presented with hemorrhoids and rectal bleeding. It is hypothesized that correction of prolapse will resolve the pathologic changes. In...

Inflammatory cloacogenic polyps (ICPs) are considered to be part of the spectrum of manifestations of mucosal prolapse, which includes solitary rectal ulcer syndrome (SRUS), rectal prolapse, intussusceptions and rectocele. The ICP is thought to result from mucosal prolapse, which produces local trauma and ischemic injury followed by inflammation, repair and regenerative changes. The estimated a...
متن کاملCOLONOSCOPIC POLYPECTOMY IN CHILDREN
34 children aged 9 months to 12 years presenting with chronic and intermittent rectal bleeding were diagnosed as having colorectal polyps by fiberoptic colonoscopy performed under sedation. Bleeding per rectum (mean duration, 15 months) was the chief presenting symptom and was present in 97% of these patients. In 85% of patients polypectomy was carried out without using general anesthesia....
متن کاملRectal bleeding and polyps.
Colorectal polyps are an important albeit uncommon cause of rectal bleeding in children. Colonoscopy promotes both rapid and accurate diagnosis and the opportunity for immediate therapeutic polypectomy. A 10 year audit of polyps diagnosed and treated endoscopically has been undertaken in the children's endoscopy unit. Twenty nine polyps were diagnosed from 730 colonoscopies; 24 were juvenile, t...
