Factors Analysis Of Pulmonary Complications After Esophagectomy For Esophageal Cancer

Objective:Research and analyze the risk factors of pulmonary complicatio ns after esophagectomy for esophageal cancer.Methods:We retrospectively analyzed the 201 patients who underwent eso phagectomy for esophageal cancer from Sep 2014 to Dec 2016 in the Thoracic Surgery Department of the First Affiliated Hospital of Kunming Medical Univ ersity,we retrospect and analyze the possible 18 risk factors,which include g ender,age,smoke history,diabetes history,hypertension history,time of operati on,blood loss volume,gastric tube or whole gastric,indwelling nasogastric tub e or not,pathological pattern,albumin,body mass index(BMI),forced vital capac ity(FVC),forced expiratory volume in 1 second(FEV1),FEV1/FVC,number of lumph nodes resected,surgery mode,and neoplasm staging.First,all dates is a nalyzed in SPSS(statistical package for social sciences),the measurement datas are analyzed by Independent-Samples T Test and the count datas are analyzed by Crosstabs(chi-square rest).Second,all dates are analyzed by Binary Logistic regression analysis in SPSS.Results:51 patients had postoperative pulmonary complications(POPCs),th e occurrence rate of POPCs is 25.37%.The results of Independent-Samples T T est and(or)chi-square rest:In the group of POPCs,the mean of body mass index(23.73±3.49)more t han the group of no POPCs(21.85±3.58)(t=3.269,p=0.001),the mean of F EV1(2.61±0.53)less than the group of no POPCs(2.81±0.52)(t=-2.433,p=0.016),the complication incidence rate of smoke history group(29.8%)obvious m ore than the non-smokers(17.1%)(x2=3.842,p=0.049),the complication incide nce rate of Ivor-Lewis(video-assisted thoracic surgery and laparoscopic surgery)operation(15.0%)obvious less than the patient by sanastomosed cervix of S weet operation(31.6%)(x2=4.526,p=0.033).Binary Logistic regression anal ysis in SPSS for all retrospected factors,the partial regression coefficent(B)of some factors(include age,hypertension history,blood loss volume,BMI,FVC,FEV1/FVC,smoke history,and time of operation)is greater than zero and their probability is lesser than 0.05.The partial regression coefficent(B)of thr ee factors(include albumin,Ivor-Lewis(video-assisted thoracic surgery and lapa roscopic surgery),and FEV1)is lesser than zero and their probability is lesser than 0.05.Conclusion(s):Older.Poor nutritional status、High body mass index、Poor lung function、hypertension history、blood loss volume、smoke history、and time of operation are independent risk factors for POPCs.Ivor-Lewis ope ration is lower danger of POPCs when compared with other theer operation mo des.Indwelling nasogastric tube,gender,pathological pattern,and neoplasm stagi ng are not risk factors for POPCs.
