Chronic Radiation

The preferred method in detection and staging of chronic radiation proctitis is colonoscopy. Moreover, endoscopy is used widely in treating patients with this disease. The main goal of endoscopic techniques is hemostasis and elimination of vascular transformations. This includes formalin application, band ligation, various types of laser irradiation, bipolar coagulation and cryotherapy. However, these methods are associated with relatively high risk of complications, whereas argon plasma coagulation and radiofrequency ablation are effective, relatively safe techniques for chronic radiation proctitis and well tolerated by patients.

Ideal Tool

Two main nonsurgical endoscopic approaches for ablating dysplastic and early cancer lesions in the esophagus have gained popularity, namely, radiofrequency ablation (RFA) and cryospray ablation (CSA). We report a uniquely suited endoscopic and near-microscopic imaging modality, three-dimensional (3D) optical coherence tomography (OCT), to assess and compare the esophagus immediately after RFA and CSA. The maximum depths of architectural changes were measured and compared between the two treatment groups. RFA was observed to induce 230~260 μm depth of architectural changes after each set of ablations over a particular region, while CSA was observed to induce edema-like spongiform changes to ~640 μm depth within the ablated field. The ability to obtain micron-scale depth-resolved images of tissue structural changes following different ablation therapies makes 3D-OCT an ideal tool to assess treatment efficacy. Such information could be potentially used to provide real-time feedback for treatment dosing and to identify regions that need further retreatment.
