Comparison of short-term surgical outcomes between complete mesenteric resection and traditional transhiatal laparoscopic surgery for Siewert type II/III esophagogastric junction adenocarcinoma.

The CME theory could be safely and effectively applied laparoscopically to treat patients with Siewert II/III AEG. Mesogastrium and lower mesoesophagus can be completely resected together with the tumor, lymph nodes, adipose tissue, and blood vessels as an "intact package," leading to better short-term outcomes.
