Medical Image Analysis Based on Endoscopic Radiofrequency Ablation Catheter System on the Treatment of Gastroesophageal Reflux Disease
Objective: Gastroesophagel reflux disease is not readily diagnosed using X-ray or even computer tomography. This study was to evaluate the endoscopic imaging for the radiofrequency ablation (RA) on the diagnosis and management of gastroesophageal reflux disease. Methods: We allocated 85 to mechanical RA and 80 patients to LTF. Primary outcome measures, including symptom scores of heartburn, regurgitation, chest pain, belching, hiccup, cough and asthma as well as proton pump inhibitors (PPIs) use, were analyzed. Results: There were 125 patients following mechanical radiofrequency ablation procedure (N = 60) or LTF (N = 65) included in the final analysis. The symptom scores were all significantly decreased as compared with the corresponding values before the two procedures in both groups (p < 0.05). After mechanical RA procedure and LTF, 30 (50%) and 45 (69.2%) patients in each group achieved complete PPIs therapy independence (p = 0.028). Comparing with LTF, the mechanical RA procedure had less effect on improving typical symptoms of heartburn and chest pain and the rate of reoperation (13% vs. 0, p = 0.003). Conclusions: Comparing with LTF in controlling GERD symptoms, the mechanical radiofrequency ablation procedure can offer equivalent relief on atypical symptoms. However, it has less effect on improving PPIs independence and avoiding reoperation.
