Summary

Hyperbaric oxygen (HBO) therapy significantly reduced radiation enteropathy in mice. This treatment lessened bowel narrowing and rigidity, suggesting HBO can prevent radiation-induced gastrointestinal damage.

Area of Science:

  • Radiation oncology
  • Gastroenterology
  • Hyperbaric medicine

Background:

  • Delayed radiation enteropathy is a significant clinical challenge following abdominopelvic radiotherapy.
  • Current management strategies for radiation enteropathy have limited efficacy.

Purpose of the Study:

  • To evaluate the efficacy of hyperbaric oxygen (HBO) in preventing delayed radiation enteropathy in a murine model.
  • To quantify the effects of HBO on intestinal structure and function post-irradiation.

Main Methods:

  • C3H mice were randomized into two groups receiving 30 Gy abdominopelvic irradiation.
  • The study group received 30 hyperbaric oxygen treatments starting 7 weeks post-irradiation.
  • Intestinal narrowing and rigidity were assessed using a stretch apparatus; gross enteropathy signs were also evaluated.

Main Results:

  • Animals treated with HBO exhibited significantly fewer gross signs of radiation enteropathy.
  • HBO treatment resulted in statistically significant reductions in ileal narrowing and rigidity.
  • A control group without radiation or HBO showed no signs of enteropathy.

Conclusions:

  • Hyperbaric oxygen therapy is a promising intervention for preventing and mitigating delayed radiation enteropathy.
  • HBO demonstrates a significant protective effect on intestinal tissue integrity and function after radiation exposure.
  • Further investigation, including human clinical trials, is warranted to confirm these findings.
