Clinical Comparison Of Artificial Pneumothorax Versus Double Lumen Intubation In Minimally Invasive Esophagectomy

Objective: To evaluate the clinical effect of artificial pneumothorax in minimally invasive esophagectomy for esophageal cancer.Methods: Clinical data of 60 patients who received minimally invasive Mckeownesophagectomy form January 2014 to june 2016 in our department of thoracic surgery were retrospectively analyzed.All patients were divided into artificial pneumothorax group(31 patients)and double lumen endotracheal intubation group(29 patients).Thethoracicoperation blood loss,thoracicoperation time,pulmonary complications,left laryngeal recurrent nerve chain lymph nodes,anastomotic leakage and other operative procedures and postoperative complications between two groups were compared.Results: There was less thoracic operation blood loss(99.35±44.15 mL vs 131.72±51.06 mL,P=0.011),more left laryngeal recurrent nerve chain lymph nodes(3.52±2.11 vs 2.41±0.73,P=0.009),lessmean duration of hospitalization(14.3±4.1dvs 19.1±11.7d,P=0.04),less mean duration of ICU stay(0.3±0.9dvs 1.2±1.1d,P=0.001),less pulmonary complications(8(25.8%)vs15(51.7%),P=0.039)in artificial pneumothorax group compared todouble lumen endotracheal intubation group.There was no significant difference inthoracicoperation time,right laryngeal recurrent nerve chain lymph nodes,recurrent laryngeal nerve injury,anastomotic leakageand cardiovascular complications(P>0.05).Conclusion:artificial pneumothoraxin minimally invasive esophagectomy is safe,feasible and effective anesthesia method;it has less thoracic operation blood loss,less mean duration of hospitalization,moreleft laryngeal recurrent nerve chain lymph nodes,less mean duration of ICU stay,less pulmonary complicationscompared to double lumen endotracheal intubation.
