Endoscopic resection of Barrett's adenocarcinoma: Intramucosal and low-risk tumours are not associated with lymph node metastases.

Intramucosal and low-risk tumours with shallow submucosal invasion up to 1200 mm were not associated with lymph node metastasis during follow-up. In case of high-risk features and/or deep submucosal invasion, endoscopic resections are not sufficient to eliminate the risk of lymph node metastasis, and surgical oesophagectomy should be carried out. These results must be confirmed by larger prospective series.
