摘要:

Whether portal vein pressure is reduced as spontaneous portal-systemic shunts are enlarged has long been disputed. We measured portal vein pressure directly by percutaneous transhepatic catheterization in one patient with cirrhosis at a 4-year interval, and demonstrated a significant reduction in portal vein pressure that had occurred along with enlargement of a collateral paraumbilical vein and splenorenal shunt during this period.

摘要:

The diagnosis, prognosis, and treatment of various liver diseases are still frequently equivocal despite the various liver function tests and invasive procedures presently available to the clinician. The introduction of the Beckman Amino Acid Analyzer Model 119 C1, greatly facilitated the determination of the individual amino acids in serum and cerebrospinal sluid, and the data thus obtained seem to help in the differentiation of some of the commoner types of liver disease. These data indicate that changes in the concentration of some of the aromatic amino acid (AAA) and branched chain amino acids (BCAA) are helpful in diognosis, evaluation of the severity of the hepatic morphologic changes, and prognosis of the type of liver disease. Moreover, the ratio between the AAA and the BCAA seems to be indicative of certain liver diseases. We describe the alterations in the amino acid patterns which may help in the diagnosis, prognosis, and treatment of patients with certain types of liver disease.

摘要:

We studied the anatomy of the esophageal hiatus using axial CT scans in 320 patients. Normally, the diaphragmatic crura are tightly opposed and closely related to the esophagus. Widening of the esophageal hiatus is readily demonstrated by CT as a separation of the diaphragmatic crura and an increased distance between the crura and esophageal wall. The incidence of widening increases with age, lending support to the hypothesis that the abnormality is acquired.In 100 patients who also had barium studies of the upper gastrointestinal tract, a sliding hiatus hernia was found in 37/43 (86.4%) patients who had a widened esophageal hiatus shown by CT. In 26 of 37 (70.2%) patients, the hernia was demonstrated on CT as a pseudomass usually filled with contrast material lying within and/or above the esophageal hiatus. Small hiatus hernias were shown without a widened esophageal hiatus in only two patients.
