K57.33
Diverticulitis of large intestine without perforation or abscess with bleeding
Clinical Classification Guidelines
Medical Intelligence & Overview
Diverticulitis of the large intestine is a condition characterized by inflammation or infection of small pouches, called diverticula, that can develop in the wall of the colon (large intestine). When these diverticula become inflamed, it leads to diverticulitis. The specific ICD-10 code K57.33 refers to a form of diverticulitis that involves bleeding but does not include perforation or abscess formation. This condition is a common gastrointestinal issue, especially among older adults, and can cause symptoms ranging from mild discomfort to significant bleeding.
Causes & Symptoms
Clinical Causes: Weak spots in the colon wall where diverticula develop, often due to increased intraluminal pressure. A diet low in fiber, leading to constipation and increased pressure inside the colon. Age-related degeneration of the colon wall tissues. Infection or inflammation of the diverticula. Obstruction or narrowing of the colon, which can increase pressure and lead to diverticula formation.
Key Symptoms: Abdominal pain, usually in the lower left side. Changes in bowel habits, such as constipation or diarrhea. Rectal bleeding, which can range from small spots of blood to more noticeable bleeding. Tenderness in the abdomen, especially in the area of the affected section of the colon. Unexplained fatigue or weakness if there is significant bleeding. Fever and chills, indicating possible inflammation or infection, though these are less common in cases without perforation.
Diagnostic & Treatment
Diagnosis Path: Medical history review and physical examination to assess symptoms and abdominal tenderness. Stool tests to detect blood and evaluate for infection. Blood tests to check for signs of infection or anemia resulting from bleeding. Imaging studies such as a computed tomography (CT) scan, which provides detailed images of the colon and helps identify inflammation, diverticula, and bleeding sources. Colonoscopy may be performed cautiously once acute symptoms resolve, to visualize the colon wall directly, identify diverticula, and assess bleeding sources. Other imaging techniques, such as angiography, might be used if bleeding is severe and ongoing.
Treatment Protocols: Bowel rest, which may involve fasting and intravenous fluids to allow inflammation to subside. Antibiotics to treat or prevent infection if indicated. Medication to manage pain and reduce inflammation. Monitoring and blood tests to evaluate ongoing bleeding and hemoglobin levels. Endoscopic procedures or angiographic interventions to control active bleeding, such as cauterization or embolization. Surgical intervention may be considered if bleeding is severe, persistent, or complicated by other conditions. Lifestyle modifications, including a high-fiber diet and adequate hydration, to prevent future episodes.
