Radiation enteritis: Diagnostic and therapeutic issues.

Area of Science:

• Gastroenterology
• Oncology
• Radiation Medicine

Background:

• Abdominal pelvic radiation therapy can cause acute or chronic small bowel lesions, known as radiation enteritis.
• Late toxicity from radiation enteritis can manifest up to 30 years post-treatment, presenting diagnostic challenges.
• Approximately 20% of patients receiving radiation therapy develop clinical signs of radiation enteritis.

Purpose of the Study:

• To summarize the clinical presentation, diagnostic challenges, and management strategies for radiation enteritis.
• To highlight the long-term implications and potential complications of radiation-induced small bowel injury.

Main Methods:

• Review of existing literature on radiation enteritis.
• Analysis of clinical manifestations, diagnostic approaches, and treatment outcomes.
• Discussion of multidisciplinary management and surgical interventions.

Main Results:

• Acute radiation enteritis symptoms typically resolve upon cessation of radiation.
• Chronic radiation enteritis can lead to significant complications including obstruction, malabsorption, and malnutrition.
• Multidisciplinary management, prioritizing nutritional support, is crucial.

Conclusions:

• Radiation enteritis poses a significant long-term risk, requiring vigilant monitoring and management.
• Surgical intervention is reserved for complications or treatment resistance, favoring intestinal resection over bypass.
• Iterative surgeries increase the risk of short bowel syndrome and long-term nutritional dependence.
