Radiofrequency ablation (RFA) is a well-established treatment for several benign, pre-malignant, and malignant disorders. Although the role of RFA has been clearly defined, new indications for luminal and extra-luminal applications of endoscopic RFA-directed therapies have emerged. RFA has recently produced promising results in patients with a variety of gastrointestinal and hepatopancreatobiliary pathologies. For example, endoscopic RFA has been used to treat patients with gastric antral vascular ectasia, chronic radiation proctitis, malignant biliary strictures, and ampullary adenomas with intraductal extension...

BACKGROUND: Chronic radiation proctitis (CRP), a common complication after radiotherapy for pelvic malignancies, compromises patient quality of life. Vascular damage and aberrant angiogenesis in the mucosal layer are essential histological features, but changes to the submucosal layer are unclear. Thus, we evaluated the histological characteristics and distribution changes of key angiogenic factors in full-layered human CRP samples. METHODS: Thirty paraffin-embedded CRP and twenty-nine non-CRP tissues were used to evaluate histopathological changes...

INTRODUCTION: Chronic radiation proctitis (CRP) usually develops 90 days or more after radiation. Currently, there is no standard available for the treatment of CRP. In argon plasma coagulation, monopolar diathermy is used to ionise the argon gas which coagulates the telengiectatic vessels in a noncontact fashion. However, there are very few studies which have reported its use in extensive CRP. We report the efficacy and safety of APC in seven patients with recurrent, extensive grade 3 radiation proctitis...

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...
