What could be the reason for the bleeding wound and pain in the rectum?

Hi,

Welcome to icliniq.com.

From the look of it (attachment removed for patient identity protection), I think this is rectal prolapse complicated by an ulcer. Rectal prolapse is a condition in which the rectum (the lower part of the large intestine) turns inside out and protrudes through the anus. This can occur as a result of the weakening of the muscles and ligaments that support the rectum, which can be caused by a variety of factors, including chronic constipation, diarrhea, aging, and previous rectal surgery. Symptoms of rectal prolapse can include: A feeling of a bulge or lump in the anus, rectal bleeding, pain or discomfort during bowel movements, incontinence (loss of control) of bowel movements, mucus or discharge from the anus, and a sense of incomplete bowel emptying. Treatment for rectal prolapse can depend on the severity of the condition. In some cases, conservative measures such as dietary changes, pelvic floor exercises, and medications may be sufficient. However, in more severe cases, surgical intervention may be necessary to repair the prolapse and prevent further complications. I advise you to get some blood workups, rectal examinations and lower gastero-intestinal (GI) endoscopy, ultrasound, and CECT (contrast-enhanced computed tomography) done. Thank you.
