Advantages and disadvantages of transthoracic approach for adenocarcinoma of the esophagogastric junction / 中华胃肠外科杂志

ABSTRACT

Adenocarcinoma of the esophaogastric junction (AEG) has anatomical characteristics of spanning two organs and anatomical sites. Thoracic surgery and gastrointestinal surgery aim at the safe resection margin of esophagus, the scope of lower mediastinal lymph node dissection and whether transthoracic surgery will increase complications. However, there are great differences and controversies in the surgical approach, surgical method, lymph node dissection and extent of resection of AEG. For Siewert II AEG via abdominal mediastinal approach, due to the limitation of exposure and the difficulty of operation, it is difficult to acquire a satisfactory proximal resection margin, and very difficult to dissect the inferior mediastinal lymph nodes. The transthoracic approach can provide adequate exposure, reduce the difficulty of operation, obtain satisfactory resection margin of esophagus and allow lower mediastinal lymph node dissection, which may bring better prognosis. Although transthoracic approach may increase the incidence of pulmonary infection, the standard development of thoracoscopic technology will overcome the disadvantage of transthoracic approach for Siewert II AEG.
