Study On Occurent States And The Risk Factors Of Early Complications After Surgery For Schistosomal Portal Hypertension

Objective:The study was to explore the incidence and related factors of early complications after surgery for schistosomal portal hypertension, and to provide a scientific basis for prevention of postoperative complications and development of perioperative prevention programe development.Methods:This was a reteospective study.323 schistosomal portal hypertension patients in Xiangyue affiliated hospital of Hunan schistosmiasis control department from January 1997 to Septenber 2009 were selected. Epidata 3.2 and SPSS 16.0 were used. General situation of cases was described. After signal factor analysis and relevant professional knowledge,15 related factors were analysed with logistic regression analysis.Results:1. The incidence of postoperative complication was 48.92%(158/323), the incidence of pulmonary complication was the highest.2. Univariate analysis result:sex, smoking history, history of bleeding, ascites, history, preoperative length of stay, total hospital days, portal vein, A/G ratio, albumin, total bilirubin, total bile acid, ammonia and right hepatic size, surgical, blood loss, blood transfusion, postoperative antibiotic use, postoperative analgesia, postoperative inhalation programe, postoperative antibiotic use of time, indwelling stomach were related to the incidence of postoperative complications (P＜0.05).3. Logistic regression analysis result:the portal vein diameter (OR= 1.152, 95%CI:1.032-1.286), A/G ratio (OR=2.674,95%CI:1.573-4.546), bleeding history(OR=1.922,95%CI:1.133-3.261),blood los(OR=3.032,95%CI:1.598-5.752), indwelling stomach tube time (OR=1.540,95%CI:1..114-2.130) were risk factors of postoperative complications within 30 days. postoperative analgesia, was minus(B=-0.580), can be considered for the protection factor.Conclusions:1. The incidence of postoperative complication was 48.92%, the incidence of pulmonary complication was the highest.2.The person of larger portal vein diameter, lower of A/G ratio, having history of bleeding, more of loss of blood, longer retention with gastric tube has greater risk of postoperative complication. But postoperative analgesia was the protection factor.
