Hyperbaric oxygen treatment for radiation proctitis

Abstract

Our objective was to assess, retrospectively, the efficacy of hyperbaric oxygen treatment in radiation proctitis in all patients who have completed treatment for this disease at the Fremantle Hyperbaric Oxygen Unit. This unit is the only one of its kind in Western Australia. Patients were assessed by a review of hospital records, blood bank records, and clinic review (if this was convenient), and all patients responded to a telephone survey. Patients were questioned regarding radiation proctitis symptoms and the degree to which each had improved. Most patients had previously been treated with radiotherapy for prostate carcinoma. Patients with proctitis mainly suffered from bleeding, diarrhoea, incontinence, and pain. In more than half of these patients, symptoms partially or completely resolved after hyperbaric oxygen treatment. Radiation-induced proctitis is a difficult clinical problem to treat and will probably become more significant with the rising incidence of diagnosis of prostate cancer. Hyperbaric Oxygen should be considered in the treatment of radiation-induced proctitis. Further prospective trials with strict protocol guidelines are warranted.
