Hyperbaric oxygen therapy heals radiation proctitis and restores rectal function
Understanding radiation proctitis and how hyperbaric oxygen therapy heals the damage
Radiation proctitis occurs as a side effect of radiation therapy for pelvic cancers including prostate, cervical, bladder and colorectal cancer. The radiation damages the lining of the rectum, leading to rectal bleeding, diarrhea, urgency to have bowel movements and pain during bowel movements. These symptoms can severely impact daily life and overall comfort.
The damage results from obliterative endarteritis — progressive destruction of blood vessel linings that creates tissue which is hypovascular, hypoxic and hypocellular. Symptoms can appear weeks to years after radiation treatment and progressively worsen. HBOT is a standard of care for radiation proctitis treatment, approved by the FDA and covered by Medicare and most private insurance companies. It reverses the tissue damage by regrowing blood vessels, restoring oxygen delivery and regenerating healthy rectal tissue.

Clinical evidence for HBOT in radiation proctitis treatment
Hyperbaric oxygen therapy is an established standard of care for radiation proctitis, supported by extensive clinical evidence and approved by the FDA and Medicare.
Resolution rates: Clinical studies demonstrate that HBOT heals radiation proctitis in up to 89% of patients. One study showed complete or significant partial resolution of symptoms in 76% of patients. Another demonstrated that HBOT significantly reduces rectal bleeding scores, diarrhea frequency and pain during bowel movements.
Pathophysiology: Radiation proctitis results from obliterative endarteritis — the progressive destruction of blood vessel linings in the rectal wall. This creates tissue that is hypovascular, hypoxic and hypocellular. Without adequate blood supply and oxygen, the rectal lining cannot maintain itself or heal from injury, leading to progressive bleeding, inflammation and tissue breakdown.
Mechanism of healing: HBOT directly reverses all three hallmarks of delayed radiation injury. It stimulates neovascularization to grow new blood vessels, delivers 1,200% more oxygen to correct tissue hypoxia, and mobilizes stem cells and stimulates fibroplasia to restore cellular populations. These mechanisms rebuild the rectal tissue that radiation destroyed.
Standard of care: HBOT is recognized as a standard of care for radiation proctitis treatment. It is approved by the FDA, covered by Medicare and reimbursed by most private insurance companies. Clinical guidelines recommend HBOT for patients with radiation proctitis that has not responded adequately to conventional management.
Safety: HBOT does not stimulate cancer cell growth — this has been conclusively demonstrated over 50 years of research. Treatment is safe for cancer survivors and is specifically designed to heal the tissue damage caused by radiation therapy.
Radiation-induced cystitis treated with hyperbaric oxygen therapy (RICH-ART)
The American Society of Colon and Rectal Surgeons' clinical practice guidelines for the treatment of chronic radiation proctitis recommend hyperbaric oxygen therapy as an effective treatment modality to reduce bleeding in patients with radiation proctitis.
Researchers in this study conducted a randomized, controlled, phase 2-3 trial (RICH-ART [Radiation Induced Cystitis treated with Hyperbaric oxygen-A Randomized controlled Trial]) at five Nordic university hospitals. All of the patients had completed at least six months of treatment and had a score of less than 80 in the urinary domain of the Expanded Prostate Index Composite Score (EPIC), and referred to participating hyperbaric clinics due to symptoms of late radiation cystitis.Hyperbaric oxygen in the treatment of severe refractory hemorrhagic radiation proctitis: a randomized controlled trial
This review found Grade B and C evidence that hyperbaric oxygen therapy reduced late-onset radiation injuries to the head and neck, bone, prostate and bladder. It also appeared to prevent osteoradionecrosis in irradiated areas and increased the effectiveness of radiation in head and neck tumors.
Hyperbaric oxygen therapy (HBOT) has been used as a treatment for radiation injuries for decades, with many publications presenting data from small series or individual cases. Moreover, we know that the hypoxic areas of tumours are more resistant to radiation. HBOT increases the oxygen tension in tissues and, theoretically, it should enhance the efficiency of radiotherapy. To better understand how HBOT works, the researchers in this study carried out a bibliographic review. They found Grade B and C evidence that at pressures exceeding 2 absolute atmospheres (ata), HBOT reduced late-onset radiation injuries to the head and neck, bone, prostate and bladder. It also appeared to prevent osteoradionecrosis after exodontia in irradiated areas. Finally, HBOT at 2 ata increased the effectiveness of radiation in head and neck tumors and achieved promising results in the local control of high-grade gliomas.Hyperbaric oxygen treatment of chronic refractory radiation proctitis: a randomized and controlled double-blind crossover trial with long-term follow-up
Hyperbaric oxygen therapy improved healing in patients with refractory radiation proctitis. Other medical management requirements were discontinued, and advanced interventions were largely avoided. Patients' bowel-specific quality of life improved.
Of 57 patients in the study, 49 (86%) experienced complete resolution or marked improvement of hematuria following hyperbaric oxygen treatment. Of the 8 patients who did not improve, 4 received fewer than 40 hyperbaric oxygen treatments and 7 prematurely terminated treatment (medical co-morbidities 4, claustrophobia 2, temporary resolution of symptoms 1).Radiation proctitis patients share their healing stories

John, who is a salt-of-the-earth kind of guy, came in after having multiple other treatments, some very painful, to stop his bladder from bleeding. Unfortunately, none of the previous treatments helped.
Most patients who come to us to try hyperbaric oxygen therapy for a damaged bladder have already tried other conservative measures, which sadly have resulted in failure. In John’s case, he even had two transfusions. He also passed painful clots from time to time that resulted in his having to make several trips to the ER. He got up frequently at night to urinate and limited his social life as a result. Hyperbarics healed John’s bladder, and the bleeding stopped. He left feeling much more enthusiastic about life.

Josephina, a 61-year-old woman, lived and took care of an elderly friend half the year on the coast of Oregon. She is a quiet spoken, thoughtful woman who had cancer in her mouth 18 years prior to coming in for hyperbaric oxygen therapy. The radiation that was used to treat her cancer many years before was very successful. However, she went to her dentist and complained of her tooth feeling loose. The radiation had started to damage the circulation in her mandible and her gums. Her tooth had died and her dentist wanted to remove it. Her dentist also thought that she had two other teeth that were threatened as well. Josephina was sent to an oral surgeon who diagnosed osteoradionecrosis, which is death of the bone due to radiation injury. The blood vessels in the jaw start to die off due to radiation damage. When this happens the bone can get very fragile and sometimes fracture which creates a much bigger problem including a long and difficult recovery. So to avoid this, and prior to taking out her tooth, her surgeon sent her for hyperbaric treatments. The Marx protocol was used which included 20 treatments prior to removing the tooth to revascularize and thus strengthen the jaw. After removing the tooth Deborah returned for the remaining 10 more session to insure the bone heals up properly. In her case, Josephina was fortunate that the bone was strengthened with hyperbarics prior to more teeth dying. Indeed, she was pleased that she did not lose any further teeth. Two years later she came back to visit and say hello. She still had all the rest of her teeth.
