Does Gastrointestinal Wall Thickness Indicate Cirrhosis?
Patients with cirrhosis frequently undergo computed tomographic (CT) scans for preoperative evaluation for transplantation and to exclude hepatocellular carcinoma. Gastrointestinal wall thickening has been noted in patients with cirrhosis and can be severe enough to lead to a misdiagnosis of ischemia, inflammation, hemorrhage or even carcinoma of the involved segments of bowel. In patients with cirrhosis, gastrointestinal wall thickening generally is caused by edema. Karahan and associates characterized the association of gastrointestinal wall thickening in patients with cirrhosis and control subjects. Seventy-seven patients with cirrhosis and 100 without cirrhosis were examined with contrast-enhanced CT imaging of the abdomen. The scans were retrospectively assessed by three radiologists. The presence of gastrointestinal wall thickness from the stomach through the descending colonic wall was determined. Malignancy was ruled out with preliminary review of the CT images and with subsequ
