“…Doppler sonography has been shown to be a valuable technique for evaluation of both the structure and perfusion of the allograft in liver-transplant recipients [1,2]. Sonographic detection of portal venous gas also has been reported in transplant recipients [1 ], and the sonognaphic appearance of portal venous gas has been well described in nontransplanted livers [3][4][5][6].…”

“…Therefore, 139 cholangiographic and ultrasound examinations could be used for further analysis. Cholangiography showed obstruction in 21 Obstruction Table 3 shows a comparison between cholangiography and ultrasound regarding the detection of obstruction. Discrepancies were found in 15 examinations (11%).…”

The ability of ultrasound to detect biliary obstruction, bile leakage and generalized ductal changes after orthotopic liver transplantation (OLT) was compared to cholangiography. Cholangiography was considered to be the gold standard. Adequate opacification of the biliary tree was achieved in 139 cholangiograms. Biliary obstruction, intermediate or large bile leakage, and generalized ductal changes were diagnosed with cholangiography in 15% (21/139), 14% (20/139), and 16% (22/139), respectively. Normal ultrasound findings could not exclude biliary stricture, generalized ductal changes, or bile leakage, and fluid collections were not correlated with bile leakage. Abnormal ultrasound findings were highly predictive of the cholangiographic diagnosis of biliary obstruction or generalized ductal changes (specificity of 98% and 100%, respectively). An irregular appearance of the bile ducts and increased periductal echogenicity proved to be characteristic features for generalized ductal changes. © 1996 John Wiley & Sons, Inc.

“…Biochemical parameters have been shown to be of limited clinical value in the immediate postoperative period (Esquivel et al 1985). Although radionuclide imaging (Brown et al 1986;Hawkins et al 1988;Loken et al 1986), ultrasonography (Dalen et al 1988;Davis et al 1989;Letourneau et al 1987a), computed tomography (Dalen et al 1988;Letourneau et al 1987b), angiography (White et al 1987) and cholangiography (Bauman et al 1989;Zajko et al 1985) have been used in the evaluation of posttransplant complications, liver biopsy remains the gold standard. Loken et al (1986), Brown et al (1986) and Hawkins et al (1988) have shown the value of DISIDA scintigraphy in liver transplant patients with biliary and vascular complications, infections and rejection.…”

Liver transplant rejection and cholestasis: comparison of technetium 99m-diisopropyl iminodiacetic acid hepatobiliary imaging with liver biopsy

et al. 1992

To determine whether the scintigraphic evaluation of technetium-99m diisopropyl iminodiacetic acid (DISIDA) uptake and excretion can distinguish among liver transplant patients with biopsy evidence for rejection, cholestasis or neither condition, we reviewed scintigrams and biopsies in 36 patients. There were 76 scintigrams with corresponding biopsies. Uptake and excretion were graded from image data on scales reflecting normal through severely abnormal values. Biopsies were evaluated for findings of cholestasis and rejection. The majority of scintigrams demonstrated normal uptake (60/75, 80%) and delayed excretion (65/76, 85%), which was most marked immediately after transplantation. One-way analysis of variance showed that the mean excretion values significantly differed between patients with normal biopsies and those with cholestasis and/or rejection (P = 0.0003). However, mean uptake scores demonstrated no statistically significant difference between these two groups of patients (P = 0.1). These findings suggest that 99mTc-DISIDA scintigraphy can differentiate between transplants with and without rejection/cholestasis but not between rejection and cholestasis. If 99mTc-DISIDA excretion is normal, rejection and cholestasis are unlikely.
