ICD-10: K55.03

Acute (reversible) ischemia of the large intestine, classified under ICD-10 code K55.03, refers to a condition where there is a sudden reduction in blood flow to a segment of the large intestine, leading to potential tissue damage. This condition is characterized by its acute onset and the possibility of reversibility if treated promptly.

Clinical Description

Definition

Acute ischemia of the large intestine occurs when blood supply is insufficient to meet the metabolic demands of the intestinal tissue. This can result from various factors, including vascular occlusion, embolism, or severe hypotension. The ischemic condition can lead to inflammation, necrosis, and, if untreated, may progress to more severe complications such as perforation or sepsis.

Symptoms

Patients with acute ischemia of the large intestine may present with a range of symptoms, including:
- Abdominal pain: Often sudden and severe, typically localized to the affected area.
- Nausea and vomiting: Commonly associated with abdominal distress.
- Diarrhea or bloody stools: Indicative of mucosal damage or bleeding.
- Fever: May occur if there is an inflammatory response or infection.

Diagnosis

Diagnosis of acute ischemia involves a combination of clinical evaluation and imaging studies. Key diagnostic tools include:
- CT scan of the abdomen: This is the preferred imaging modality, as it can reveal bowel wall thickening, pneumatosis intestinalis, or vascular occlusion.
- Ultrasound: Can be used in some cases, particularly in emergency settings.
- Colonoscopy: May be performed to assess the mucosal surface and obtain biopsies if necessary.

Treatment

The management of acute ischemia of the large intestine focuses on restoring blood flow and addressing the underlying cause. Treatment options may include:
- Surgical intervention: In cases of significant ischemia or necrosis, resection of the affected bowel segment may be necessary.
- Endovascular procedures: Such as angioplasty or stenting, can be employed to relieve vascular occlusions.
- Supportive care: Including fluid resuscitation and antibiotics, especially if there is a risk of infection.

Prognosis

The prognosis for patients with acute (reversible) ischemia of the large intestine largely depends on the timeliness of diagnosis and intervention. If treated early, the condition can often be reversed without significant long-term complications. However, delays in treatment can lead to serious outcomes, including bowel necrosis and the need for more extensive surgical procedures.

Conclusion

ICD-10 code K55.03 encapsulates a critical condition that requires prompt recognition and management. Understanding the clinical presentation, diagnostic approaches, and treatment options is essential for healthcare providers to ensure optimal patient outcomes.
