Abstract

To explore the effectiveness and safety of laparoscopic transhiatal complete mesenteric resection (CME) surgery compared with those of the traditional laparoscopic transhiatal approach in the treatment of Siewert II/III adenocarcinoma of the esophagogastric junction (AEG). Ninety-nine patients with Siewert type II/III AEG were enrolled and divided into two groups: the laparoscopic CME transhiatal approach (CEM-TH, n = 61) group and traditional laparoscopic transhiatal (TH, n = 38) group. Intraoperative and postoperative clinical data of both groups were analyzed. The laparoscopic trasihiatal surgery was technically successful in all patients. The surgical time, intraoperative bleeding, and hospital stay were all significantly (P < 0.05) reduced in the CME-TH group compared with those in the TH group. The levels of white blood cells on postoperative day (POD) 1 and 5, postoperative CRP on POD 3 and 5, and postoperative PCT were significantly (P < 0.05) lower while lymph nodes were harvested significantly (P < 0.05) more in the CME-TH group than in the TH group. Complications were not significantly (P > 0.05) different between two groups. No death occurred within 90days. 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.
