Surgical strategies for early esophageal adenocarcinoma.

The need for extensive surgical resection for early-stage esophageal adenocarcinoma has been challenged by the increasing frequency of early detection in patients with Barrett's esophagus undergoing surveillance endoscopy. Limited endoscopic or surgical procedures are promoted as alternatives to radical esophagectomy and lymphadenectomy in such patients. Currently available data show that limited surgical resection of the distal esophagus with regional lymphadenectomy and interposition of an isoperistaltic jejunal segment is a safe and oncologically adequate procedure in this situation and provides good quality of life. This is in contrast to endoscopic ablation or endoscopic mucosal resection, which are associated with high tumour recurrence rates and persistence of premalignant Barrett esophagus. New technologies for accurate prediction of the presence and pattern of lymphatic spread-e.g. sentinel node techniques and artificial neural networks-may allow a further reduction of the invasiveness of surgical resection without compromising cure rates.
