OBJECTIVE: Radiation proctitis (RP) is a complication of pelvic radiotherapy which affects both the host and microbiota. Herein we assessed the radiation effect on microbiota and its relationship to tissue damage using a rectal radiation mouse model. DESIGN: We evaluated luminal and mucosa-associated dysbiosis in irradiated and control mice at two postradiation time points and correlated it with clinical and immunological parameters. Epithelial cytokine response was evaluated using bacterial-epithelial co-cultures...

Gastric antral vascular ectasia (GAVE) and chronic radiation proctitis (CRP) are well-known causes of repeated gastrointestinal bleeding and iron deficiency anemia. Argon plasma coagulation (APC) is the most common endoscopic therapy used, but some patients need multiple APC sessions. Radiofrequency ablation (RFA) is recently used in GAVE and CRP treatment with promising results. In this case series, we analyzed data for 15 patients with GAVE and 5 patients with CRP that had multiple prior APC treatment. They were treated with RFA HALO 90 catheter (HALO90 Ablation Catheter System; Covidien, GI Solutions, Sunnyvale, CA) in our tertiary referral center...

For decades, hyperbaric oxygen therapy has been considered a treatment option in patients with chronic radiation-induced proctitis after pelvic radiation therapy. Refractory cases of chronic radiation-induced proctitis include ulceration, stenosis, and intestinal fistulas with perforation. Appropriate treatment needs to be given. In the present study, we assessed the efficacy of hyperbaric oxygen therapy in five patients with radiation-induced rectal ulcers. Significant improvement and complete ulcer resolution were observed in all treated patients; no side-effects were reported...

Radiation therapy is a viable option in managing potentially life-threatening malignancies including prostate cancer. It is known that pelvic radiation can result in injury of the distal large bowel with the development of radiation proctitis. Despite reports from retrospective studies, there is a lack of direct endoscopic and histologic evidence of external pelvic radiation injury to the ileal pouch-anal anastomosis. We present a case of a 68-year-old male with pouchitis resulting from pelvic radiation for prostate cancer...

REVIEW
Gerhard G Grabenbauer, Göbel Holger
Possible toxic effects following radiation and chemotherapy of gastrointestinal tumours may cause a depletion of the mucosal barrier within the radiation volumes with severe mucositis. Diarrhoea, nausea, emesis and severe malabsorption followed by infections with dehydration and electrolyte disorders have to be encountered. For prevention and treatment of oropharyngeal mucositis an oral care protocol, oral cryotherapy together with benzydamine mouthwash may be recommended. Lower gastrointestinal diarrhoea is best treated by Octreotide (>100 μg s...
