K57.20
Diverticulitis of large intestine with perforation and abscess without bleeding
Clinical Classification Guidelines
Medical Intelligence & Overview
Diverticulitis of the large intestine is a condition where small pouches, known as diverticula, that develop in the colon become inflamed or infected. When these pouches perforate, or tear, the contents of the colon can spill into the abdominal cavity, leading to a perforation. This can also lead to the formation of an abscess — a pocket of pus caused by infection. The specific condition identified with ICD-10 code K57.20 involves diverticulitis with perforation and abscess formation, but notably without bleeding. This condition requires prompt medical attention to prevent complications and improve outcomes.
Causes & Symptoms
Clinical Causes: A diet low in fiber, leading to increased pressure within the colon Aging, which weakens colon walls Chronic constipation causing strain and pressure on the bowel wall Genetic factors that predispose to diverticula formation Obesity and physical inactivity Use of certain medications, such as corticosteroids or nonsteroidal anti-inflammatory drugs (NSAIDs) Underlying inflammatory or connective tissue disorders
Key Symptoms: Persistent abdominal pain, often on the lower left side Fever and chills indicating infection Tenderness in the abdomen, especially upon touch Nausea or vomiting due to inflammation or perforation Changes in bowel habits, such as constipation or diarrhea Signs of abscess, including localized swelling or palpable mass
Diagnostic & Treatment
Diagnosis Path: Medical history review and physical examination to assess abdominal tenderness and signs of inflammation Blood tests to identify elevated white blood cell count, signifying infection Imaging studies such as abdominal CT scan to visualize inflamed diverticula, detect perforation, and locate abscesses Ultrasound imaging may be used to identify abscess formation In some cases, additional tests like colonoscopy are deferred until inflammation subsides to reduce perforation risk
Treatment Protocols: Hospitalization for intravenous antibiotics to treat infection NPO status (nothing by mouth) to rest the bowel, often coupled with IV fluids Drainage of abscesses through percutaneous or surgical procedures if necessary Surgical intervention in cases where perforation is extensive, abscesses are unresponsive to antibiotics, or there's risk of generalized peritonitis Post-treatment care includes antibiotics, gradual reintroduction of diet, and monitoring for potential recurrent episodes Lifestyle modifications such as increased dietary fiber intake, regular exercise, and weight management to reduce future risk
