Clinical Presentation of Diffuse Acute Infarction of Large Intestine (ICD-10 Code K55.042)

Diffuse acute infarction of the large intestine, classified under ICD-10 code K55.042, is a serious medical condition characterized by the death of intestinal tissue due to inadequate blood supply. Understanding its clinical presentation, signs, symptoms, and patient characteristics is crucial for timely diagnosis and management.

Clinical Presentation

The clinical presentation of diffuse acute infarction of the large intestine typically includes a combination of gastrointestinal symptoms and systemic signs. The condition can manifest suddenly, often requiring immediate medical attention.

1. Abdominal Pain: Patients commonly report severe, crampy abdominal pain that may be diffuse or localized, often in the lower abdomen. The pain can be sudden in onset and may worsen over time[1].

2. Nausea and Vomiting: Accompanying the abdominal pain, patients may experience nausea and vomiting, which can lead to dehydration and electrolyte imbalances[1].

3. Diarrhea or Constipation: Changes in bowel habits are common. Patients may present with diarrhea, which can be bloody, or constipation due to bowel obstruction[1][2].

4. Fever: A low-grade fever may be present, indicating an inflammatory response to the infarction[1].

5. Signs of Peritonitis: In severe cases, signs of peritonitis, such as abdominal rigidity and rebound tenderness, may develop, indicating a more serious complication[1].

Signs and Symptoms

The signs and symptoms of diffuse acute infarction of the large intestine can vary based on the extent of the infarction and the patient's overall health. Key signs include:

• Abdominal Tenderness: On physical examination, there is often tenderness in the abdomen, particularly in the lower quadrants[1][2].
• Bowel Sounds: Auscultation may reveal decreased or absent bowel sounds, suggesting reduced intestinal activity[1].
• Signs of Shock: In cases of significant blood loss or sepsis, patients may exhibit signs of shock, including hypotension, tachycardia, and altered mental status[1][2].

Patient Characteristics

Certain patient characteristics may predispose individuals to diffuse acute infarction of the large intestine:

1. Age: Older adults are at higher risk due to age-related vascular changes and comorbidities[1][2].
2. Vascular Disease: Patients with a history of cardiovascular disease, peripheral vascular disease, or conditions leading to compromised blood flow (e.g., atherosclerosis) are more susceptible[1].
3. Coagulation Disorders: Individuals with clotting disorders or those on anticoagulant therapy may have an increased risk of mesenteric ischemia leading to infarction[1][2].
4. Previous Abdominal Surgery: A history of abdominal surgeries can lead to adhesions, which may compromise blood flow to the intestines[1].

Understanding K55.042: Diffuse Acute Infarction of the Large Intestine

ICD-10 code K55.042 refers to Diffuse Acute Infarction of the Large Intestine, a serious medical condition characterized by the loss of blood supply to a significant portion of the large intestine, leading to tissue death (necrosis). This condition can arise from various causes, including vascular occlusion, embolism, or thrombosis, and it often presents with severe abdominal pain, distension, and systemic symptoms such as fever and tachycardia.

Standard Treatment Approaches

The management of diffuse acute infarction of the large intestine typically involves a combination of medical and surgical interventions, depending on the severity of the condition and the patient's overall health status. Here are the standard treatment approaches:

1. Initial Assessment and Stabilization

• Emergency Evaluation: Patients presenting with symptoms suggestive of intestinal infarction require immediate evaluation, including a thorough history, physical examination, and laboratory tests.
• Fluid Resuscitation: Intravenous fluids are administered to address dehydration and maintain hemodynamic stability.
• Pain Management: Analgesics are provided to manage severe abdominal pain.

2. Diagnostic Imaging

• CT Scan: A contrast-enhanced CT scan of the abdomen is often performed to confirm the diagnosis, assess the extent of the infarction, and identify any complications such as perforation or abscess formation.

3. Surgical Intervention

• Exploratory Laparotomy: In cases where there is evidence of significant bowel necrosis, surgical intervention is often necessary. An exploratory laparotomy allows for direct visualization of the intestines.
• Resection of Necrotic Tissue: The affected segment of the large intestine is typically resected. This may involve a partial colectomy, depending on the extent of the infarction.
• Colostomy or Ileostomy: In some cases, a temporary colostomy or ileostomy may be created to divert fecal flow and allow the remaining bowel to heal.

4. Postoperative Care

• Monitoring: Patients are closely monitored for signs of infection, bowel function, and overall recovery.
• Nutritional Support: Once the patient is stable, nutritional support may be initiated, often starting with parenteral nutrition if the bowel is not yet functional.

5. Medical Management

• Antibiotics: Broad-spectrum antibiotics are typically administered to prevent or treat infections, especially if there is bowel perforation or peritonitis.
• Anticoagulation Therapy: If the infarction is due to a thrombotic event, anticoagulation therapy may be initiated to prevent further clot formation.

Prognosis and Follow-Up

The prognosis for patients with diffuse acute infarction of the large intestine largely depends on the timeliness of diagnosis and intervention. Early surgical intervention is critical to improving outcomes and reducing mortality rates. Long-term follow-up may be necessary to monitor for complications such as bowel obstruction or changes in bowel habits.
