TSLG versus LTH for Siewert Type II AEG: Advantages and Efficacy

Transthoracic single-port-assisted laparoscopic gastrectomy (TSLG) demonstrates technical safety and feasibility in comparison to laparoscopic transhiatal approach (LTH) for Siewert type II adenocarcinoma of the esophagogastric junction. In a retrospective study, TSLG showed advantages, including increased harvested lymph nodes, reduced lower mediastinal lymph nodes, and longer proximal margins. The R0 gastrectomy rate was higher in the TSLG group, highlighting its potential as an effective addition to LTH surgery, especially when lower mediastinal lymph node metastases are suspected.
