K51.311
Ulcerative (chronic) rectosigmoiditis with rectal bleeding
Clinical Classification Guidelines
Medical Intelligence & Overview
Ulcerative (chronic) rectosigmoiditis is a form of inflammatory bowel disease that affects the rectum and sigmoid colon— the last parts of the large intestine. This condition leads to inflammation, ulcers, and bleeding, causing discomfort and other digestive issues. It is a long-term (chronic) condition that requires ongoing management to control symptoms and prevent complications.
Causes & Symptoms
Clinical Causes: Genetic predisposition, making some individuals more susceptible Immune system malfunction, where the body's immune response attacks the colon's lining Environmental factors, such as diet and stress, that may influence disease activity Possibly related to microbial imbalance in the intestines
Key Symptoms: Rectal bleeding, often visible in stool or toilet paper Frequent need to have bowel movements (urgent diarrhea) Abdominal pain and cramping, particularly in the lower abdomen Urgency and sensation of incomplete evacuation Occasional fever or fatigue during flare-ups Mucus in the stool Unintended weight loss in some cases
Diagnostic & Treatment
Diagnosis Path: Medical history review and physical examination Laboratory tests such as blood tests to detect anemia or infection markers Stool tests to rule out infections and check for bleeding Colonoscopy with biopsy to visualize the colon lining directly and obtain tissue samples Imaging studies like barium enema or CT scan if necessary
Treatment Protocols: Aminosalicylates (e.g., mesalamine) to decrease inflammation in the colon Corticosteroids for short-term relief during flare-ups Immunosuppressant drugs such as azathioprine to modulate the immune response Biologic therapies targeting specific immune pathways in severe cases Antidiarrheal agents to control diarrhea Nutritional modifications to support recovery and reduce symptom severity Surgical intervention, like removal of the affected colon segment, in cases of severe, unresponsive disease or complications
