[Radioactive Enteritis and Gut Microecology].

Radioactive enteritis(RE)is one of the most serious and common complications of intestinal tract caused by radiotherapy for malignant tumors in abdominal cavity,pelvic cavity,or retroperitoneum.Involved intestinal diseases are widespread,complex,and persistent,which make treatment difficult and ineffective.Short bowel syndrome can develop in some serious cases.Gut flora is the largest and most complex micro-ecosystem in human body and has a wide range of functions.Studies have shown that intestinal flora plays an important role in radiation-induced RE.This article summarizes recent research advances in the relationship between RE and gut flora.
