About this trial

The incidence of esophagogastric junction has been increasing in recent years, and surgery is an important method for the treatment of adenoma at the esophagogastric junction. Currently, there is a great controversy about the surgical method of Siewert II, mainly choosing the right chest or the left chest for thoracic surgery. Therefore, it is of great significance to further study the surgical methods of Siewert II esophagogastric junction adenoma. Objective: To compare the safety, feasibility, and clinical efficacy of endoscopic Ivor-Lewis versus laparoscopic extended abdominal gastrectomy for Siewert type Ⅱadenocarcinoma at the resectable esophagogastric junction.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Histologically confirmed EGJ type II adenocarcinoma

Pretreatment stage CT1-4A, N0-3, M0

For cT4a stage patients, their resectable properties must be clearly verified before randomization

For locally advanced tumors (CT3-T4 or N+), all 4 cycles of chemotherapy (FLOT) were completed before surgery.

Disqualifiers

Histologically confirmed EGJ type I and III adenocarcinoma

Tumor spread over 5 cm proximal to EGJ

Clinically significant (active) heart disease (i.e. symptomatic coronary artery disease or myocardial infarction within the last 12 months) resulting in left ventricular ejection fraction<50%(determined by echocardiography)

Clinically significant lung diseases (forced expiratory volume in 1 second (FEV1)<1.5 l/s)
