Abstract

Endoscopic ultrasound (EUS) is useful for detecting depth of invasion and nodal involvement in patients with early Barrett's neoplasia (EBN), precluding endoscopic management. This study aimed to determine whether the lesion morphology of the EBN shown on high-resolution endoscopy predicts EUS and histologic tumor stage. Retrospective series from two tertiary referral centers were studied. Patients with EBN referred for EUS evaluation before treatment were identified, and data were collected from endoscopies, a database, and case notes. All patients had high-resolution endoscopy followed by radial EUS. This study included 50 patients (22 men) with a median age of 69 years (interquartile range, 60-79 years). Visible lesions in the Barrett's segment were described as Paris types 0-1 (n = 9), 0-IIb (n = 12), 0-IIa (n = 12), 0-IIa + IIc (n = 6), and 0-IIc (n = 5). Of the 50 patients, 46 (92%) had either EMR (n = 17), esophagectomy (n = 23), or both (n = 6). All 12 patients (100%) with Paris 0-IIb lesions had T0/T1 m staging on EUS confirmed with resection histology. The sensitivity for EUS T-staging for Paris classification was 71.4% for type 0-I, 100% for type 0-IIb, 83% for type 0-IIa, 66.7% for type 0-IIa + IIc, and 66.7% for ty...Continue Reading
