What is Radiation Enteritis?

Radiation enteritis is an intestinal complication caused by radiotherapy for malignant tumors in the pelvic cavity, abdominal cavity, or retroperitoneum. It can affect the small intestine, colon, and rectum respectively, and is therefore also known as radiation proctitis, colitis, or enteritis. Its occurrence is closely related to factors such as radiation dose, duration, intestinal segment involved, and bowel mobility. It can be classified into acute and chronic forms according to the disease course. Common clinical symptoms include nausea, vomiting, diarrhea, and passage of blood-like stools. Diagnosis is typically based on a history of radiotherapy, clinical manifestations, endoscopic examination, X-ray imaging, and other diagnostic methods. Treatment strategies depend on the severity of the condition and may include general supportive care, pharmacological therapy, and surgical intervention.
