Outcomes
Our primary outcome was successful eradication of adenocarcinoma taken as subsequent endoscopies showing no visual nodularity and biopsy specimen clear of adenocarcinoma. Secondary outcomes included long-term recurrence of disease and mortality of patients within 5 years. Length of stay and 30-day in-hospital morbidity was also tracked and classified into major and minor complications according to the Clavien-Dindo classification (minor: class I and II, major: class III and above) (18).
