Progress in diagnosis and treatment of portal vein gas in adult acute abdomen patient / 国际外科学杂志

ABSTRACT

Portal vein gas refers to the accumulation of gas in the main portal vein and its tributaries caused by various reasons. It is often found in acute abdomen patients caused by intestinal obstruction and ischemia. CT is an important examination for the definite diagnosis. In recent years, with the deepening understanding of the pathogenesis of portal vein gas and the development of radiological imaging technology, portal vein gas is no longer considered as the indication of surgical exploration in acute abdomen patients. However, once it is found, intestinal ischemia and necrosis should been evaluated carefully in patients. According to the etiology, vital signs and auxiliary examination, the treatment decision can be made to avoid improper selection of treatment plan and delay the treatment opportunity. For patients with intestinal necrosis, surgical treatment should be active. This paper reviews the current situation of diagnosis and treatment of portal vein gas in adult acute abdomen patients.
