ICD-10: K55.049

The ICD-10 code K55.049 refers to "Acute infarction of large intestine, extent unspecified." This condition is characterized by the sudden loss of blood supply to a portion of the large intestine, leading to tissue death (necrosis) due to ischemia. Below is a detailed clinical description and relevant information regarding this diagnosis.

Clinical Description

Definition

Acute infarction of the large intestine occurs when there is a sudden interruption of blood flow to the colon, which can result from various factors, including embolism, thrombosis, or vascular compromise. This condition can lead to significant morbidity and, if not treated promptly, can result in severe complications, including perforation, peritonitis, and sepsis.

Symptoms

Patients with acute infarction of the large intestine may present with a range of symptoms, including:
- Abdominal pain: Often severe and sudden in onset, typically localized to the affected area of the colon.
- Nausea and vomiting: These symptoms may accompany the abdominal pain.
- Diarrhea or bloody stools: Patients may experience changes in bowel habits, including the presence of blood in the stool.
- Fever: A systemic response to the underlying ischemia and potential infection.
- Signs of shock: In severe cases, patients may exhibit signs of hypovolemic shock due to fluid loss and systemic infection.

Risk Factors

Several risk factors can predispose individuals to acute infarction of the large intestine, including:
- Atherosclerosis: Narrowing of the blood vessels due to plaque buildup can lead to reduced blood flow.
- Cardiac conditions: Arrhythmias or heart failure can contribute to embolic events.
- Hypercoagulable states: Conditions that increase the risk of blood clot formation can lead to thrombosis in the mesenteric vessels.
- Age: Older adults are at higher risk due to the prevalence of vascular diseases.

Diagnosis

Diagnosis of acute infarction of the large intestine typically involves:
- Clinical evaluation: A thorough history and physical examination to assess symptoms and risk factors.
- Imaging studies: CT scans of the abdomen are commonly used to visualize the colon and assess for signs of ischemia, such as bowel wall thickening, pneumatosis intestinalis, or portal venous gas.
- Laboratory tests: Blood tests may reveal leukocytosis, elevated lactate levels, and other markers of infection or ischemia.

Treatment

Management of acute infarction of the large intestine often requires urgent intervention, which may include:
- Surgical intervention: In cases of significant necrosis, resection of the affected bowel segment may be necessary.
- Supportive care: This includes fluid resuscitation, electrolyte management, and antibiotics to address potential infections.
- Monitoring: Close observation in a hospital setting is essential to manage complications and ensure recovery.
