Thoracoscopic-assisted four-phase esophagectomy with four-field lymph node dissection for esophageal cancer: case report and description of a new technique.

Complete (R0) resection and extent of lymphadenectomy are important prognostic factors for survival in patients undergoing surgery for esophageal carcinoma. We describe the first case of combined open and thoracoscopic esophagectomy with extended lymphadenectomy including abdominal, cervical, right, and left mediastinal (four-field, four-phase) nodal clearance in a 37-year-old woman with squamous cell carcinoma of the esophagus. This report provides a tailored strategy to achieve a high level of tumor clearance and complete resection. The approach described challenges the limitations of standard radical nodal clearance and may encourage surgeons to consider more extensive resections.
