Quality evaluation of guidelines for the diagnosis and treatment of radiation enteritis

To systematically evaluate the guidelines for the diagnosis and treatment of radioactive enteritis, compare their differences and reasons and provide some reference for updating them.

This study used guidelines related to radiation enteritis by searching a database. Four independent reviewers used the AGREE II evaluation tool to evaluate the quality of the included guidelines, collate their main recommendations, and analyze the highest evidence supporting the main recommendations.

Six diagnostic and therapeutic guidelines for radiation enteritis were included in this study, one of which, the American Society for Gastrointestinal Endoscopy guidelines, had an overall score of over 60%, which is worthy of clinical recommendation. In the diagnosis and treatment of radioactive rectal injury, the recommendations for hemorrhagic endoscopic treatment are mature and mainly include (I) argon plasma coagulation; (II) formalin treatment; (III) bipolar electrocoagulation; (IV) heater probe; (V) radiofrequency ablation; and (VI) cryoablation.

The methodological quality of radioactive enteritis guidelines is unequal; even in the same guidelines, different domains have a large difference. For radioactive rectal damage diagnosis, a type of endoscopic treatment recommendation is more mature, but the overall diagnosis and treatment of radioactive enteritis still lacks high-quality research evidence.
