[Radiofrequency ablation for Barret's esophagus].
Barrett's esophagus consists of the replacement of normal squamous epithelium by a specialised columnar lined epithelium referred to as intestinal metaplasia in the esophagus. It represents a premalignant lesion. The prevalence of Barrett's esophagus is around 1.6%. Esophageal adenocarcinoma results from the development of dysplasia progressing from low to high grade dysplasia and finally adeno...
متن کاملManaging Barrett’s esophagus with radiofrequency ablation
Barrett's esophagus (BE) is a well-established pre-malignant lesion for esophageal adenocarcinoma, a condition that carries a dismal five-year overall survival rate of less than 15%. Among several available methods to eliminate BE, radiofrequency ablation (RFA) provides the most efficient modality, since it has been demonstrated to successfully eradicate BE with or without dysplasia with accept...
متن کاملRadiofrequency ablation in Barrett's esophagus with dysplasia.
BACKGROUND Barrett's esophagus, a condition of intestinal metaplasia of the esophagus, is associated with an increased risk of esophageal adenocarcinoma. We assessed whether endoscopic radiofrequency ablation could eradicate dysplastic Barrett's esophagus and decrease the rate of neoplastic progression. METHODS In a multicenter, sham-controlled trial, we randomly assigned 127 patients with dy...
متن کاملMonitoring Radiofrequency Ablation Using Real-Time Ultrasound Nakagami Imaging Combined with Frequency and Temporal Compounding Techniques
Gas bubbles induced during the radiofrequency ablation (RFA) of tissues can affect the detection of ablation zones (necrosis zone or thermal lesion) during ultrasound elastography. To resolve this problem, our previous study proposed ultrasound Nakagami imaging for detecting thermal-induced bubble formation to evaluate ablation zones. To prepare for future applications, this study (i) created a...
متن کاملThermographic real-time-monitoring of surgical radiofrequency and microwave ablation in a perfused porcine liver model
Radiofrequency ablation (RFA) and microwave ablation (MWA) are currently the dominant modalities to treat unresectable liver tumors. Monitoring the ablation process with b-mode-sonography is often hampered by artefacts. Furthermore, vessels may cause cooling in the adjacent tumor target (heat-sink-effect) with risk of local recurrence. The present study evaluated infrared-thermography to monito...
