Background and study aimsEndoscopic resection (ER) is curative for early-stage oesophageal adenocarcinoma (OAC) without high-risk features. Piecemeal endoscopic mucosal resection (pEMR) prevents assessment of lateral margins, complicating risk estimation for neoplastic recurrence. We investigated risk factors for residual and recurrent OAC post-pEMR. MethodsWe performed a longitudinal study of two independent patient cohorts: the test cohort, who underwent piecemeal or en-bloc ER, (n=138) and t...
