title: [Study on risk factors of early complications after surgery for schistosomal portal hypertension].
abstract: OBJECTIVE
  To explore the related factors of early complications after surgery for schistosomal portal hypertension, so as to provide a scientific basis for prevention of postoperative complications and development of perioperative prevention programe.
  
  
  METHODS
  Case data of patients with schistosomal portal hypertension in Xiangyue Hospital affiliated to Hunan Institute of Parasitic Diseases from January, 2000 to September, 2009 were collected. With single factor analysis and relevant professional knowledge, related factors were analysed with logistic regression analysis.
  
  
  RESULTS
  A total of 52 related factors from the data of 323 cases were analysed with univariate analysis, indicating that 17 factors, including sex, history of bleeding, history of smoking, history of ascites, preoperative length of stay, diameter of portal vein, A/G ratio, albumin, total bilirubin, blood ammonia, total bile acid, operative mode, blood loss, blood transfusion, size of the right liver, postoperative analgesia, time of indwelling gastric tube, were related to the incidence of postoperative complications (all P values < 0.05). Logistic regression results showed the portal vein diameter, A/G ratio, bleeding history, blood loss, time of indwelling gastric tube were risk factors of postoperative complications within 30 days. Postoperative analgesia was considered as the protection factor.
  
  
  CONCLUSIONS
  The patients with larger portal vein diameter, lower of A/G ratio, history of bleeding, more loss of blood, longer retention with gastric tube have greater risk of postoperative complication. Loss of blood in operation was the greatest risk, but postoperative analgesia was the protection factor.
