The investigators conducted a retrospective analysis of cases from their center over the past five years, stratifying patients into Low Pa0₂ Group and Normal Pa0₂ Group based on postoperative oxygen levels and comparing the incidence of anastomotic leakage between the groups. The goal is to establish whether hypoxia is a causative risk factor and whether correcting it can reduce the risk of anastomotic leakage.",[23,24,25,26,27],"Esophageal Carcinoma","Esophageal Adenocarcinoma","Esophagectomy","PaO2","Esophageal Anastomotic Leakeage",[29],"Effect of Postoperative PaO₂ on Anastomotic Leakage Following Esophagectomy","RECRUITING","2026-06-13",{"date":33,"type":34},"2026-06-16","ACTUAL",{"date":36,"type":34},"2021-01-01",{"date":38,"type":19},"2026-12-01",{"name":40,"class":41},"Sun Yat-sen University","OTHER",6,""]
