A computer program analysis of the effect on survival of 74 preoperative factors was performed as part of a prosepctive study of the emergency portacaval shunt in 146 unselected patients with bleeding esophageal varices due to alcoholic cirrhosis. Only ascites, a serum glutamic oxalacetic transaminase level of 100 units or more, and a requirement for 5,000 ml or more of blood transfusion were associated with a statistically significant decrease in survival. However, none of these factors are contraindications to operation because their presence permits a survival rate of 37 to 40%. The only contraindication to emergency portacaval shunt is the combined presence of ascites, jaundice, encephalopathy, and severe muscle wasting, a constellation that was incompatible with survival beyond one year.
作为对146例因酒精性肝硬化导致食管静脉曲张出血的未经挑选患者进行急诊门腔分流术前瞻性研究的一部分，对74个术前因素对生存率的影响进行了计算机程序分析。只有腹水、血清谷草转氨酶水平在100单位及以上，以及需要输注5000毫升或更多的血液与生存率在统计学上有显著下降相关。然而，这些因素都不是手术的禁忌症，因为它们的存在允许生存率达到37%至40%。急诊门腔分流术唯一的禁忌症是腹水、黄疸、脑病和严重肌肉萎缩同时存在，这种情况与超过一年的生存率不相容。
