En-bloc esophagectomy for esophageal cancer.

Background: The operative approach for esophageal cancer varies from simple palliative resection to extended esophagectomy with 3-field lymph-node dissection or en-bloc esophagectomy (EBE) depending on tumor and patient status and surgical strategy of the surgeon. The merits and demerits of such EBE are yet to be determined.

Methods: A literature review was done regarding EBE for esophageal cancer.

Results: Twenty articles describing EBE were reported from experienced institutions during the last 20 years and were selected for this study. The conclusions drawn from those articles showed that EBE would be a safe procedure with acceptable morbidity and low mortality rates when performed by an experienced surgeon. When strict patient selection criteria were maintained, this procedure decreased locoregional recurrence and improved long-term survival rates.

Conclusions: EBE would be the treatment of choice in selected patients presenting with esophageal cancer. Development of meticulous preoperative risk assessment and optimum postoperative care may further improve the acceptability of this procedure with minimum morbidity and acceptable mortality rates.
