Surgical strategy for adenocarcinoma of esophagogastric junction / 中华胃肠外科杂志

ABSTRACT

The incidence of adenocarcinoma of esophagogastric junction (AEG) has been increasing. The surgical strategy for AEG remains controversial. The Siewert definition of AEG facilitates decision of surgical approach, while TNM stage for AEG contributes to prognosis evaluation and clinical decision making. Generally, transthoracic procedure is suitable for Siewert I and transhiatal is suitable for Siewert III. The lymph node drainage of AEG is characterized by simultaneous drainage to the mediastinal and abdominal lymphatic pathways. The optimal lymphadenectomy depends on the distribution of lymph node metastasis. Reconstruction of the digestive tract requires safety as a precondition, taking into account of postoperative complications and quality of life. For AEG patients undergoing total gastrectomy, Roux-en-Y anastomosis is more common. For those undergoing proximal gastrectomy, esophageal residual stomach (tubular stomach) anastomosis is more common, but the proportion of postoperative reflux esophagitis is higher. Some documents have revealed advantages of minimally invasive laparoscopic operation for AEG, but higher level evidences is needed.
