Seattle protocol vs narrow band imaging guided biopsy in screening of Barrett's esophagus in gastroesophageal reflux disease patients
Barrett's esophagus has 0.5% to 7% risk of progression to esophageal adenocarcinoma. The method of obtaining biopsies to diagnose Barrett's is challenging. Seattle protocol has been considered as the gold standard, however its difficulty limits its applicability in practice. Narrow band im...

description | Barrett's esophagus has 0.5% to 7% risk of progression to esophageal adenocarcinoma. The method of obtaining biopsies to diagnose Barrett's is challenging. Seattle protocol has been considered as the gold standard, however its difficulty limits its applicability in practice. Narrow band imaging guided biopsy has been proposed as an alternative. To investigate the accuracy, sensitivity, specificity and applicability of Narrow band guided biopsy as a screening tool for Barret's esophagus in gastroesophageal reflux patients. Endoscopy was done in 2 different sessions 2 weeks apart for 100 patients in Alexandria, Egypt. Patients had at least one of the following: Chronic Gastroesophageal reflux disease, frequent Gastroesophageal reflux disease, or two or more risk factors for Barrett's esophagus. All patients with known Barrett's esophagus were excluded. Seventeen patients had Barrett's esophagus either by one of the two techniques or by both, 4 patients by both methods, 7 patients by narrow band imaging alone and 6 patients by Seattle protocol alone (P < .001, κ = 0.461). Sensitivity, specificity, negative predictive value and positive predictive value for Seattle protocol were 58.8%, 100%, 92.2%, 100% vs 76.5%, 100%, 95.4%, 100% respectively for narrow band imaging. A mean of 7.73 samples/patient was taken in Seattle protocol vs 3.42 samples in narrow band imaging (P < .001). A mean of 8.63 minutes was consumed in Seattle protocol vs 2.65 minutes in narrow band imaging (P < .001). Narrow band imaging guided biopsy might have higher accuracy, sensitivity and negative predictive value as well as fewer number of biopsies and shorter time of the procedure compared to Seattle protocol which might increases its applicability as screening protocol for Barrett's esophagus. However, further larger multicentric studies are needed. |
