The utility of CT for predicting bile leaks in hepatic trauma.
    Emergency radiology, 2015, Volume: 22, Issue:2

    The purpose of this study was to determine the efficacy of CT to predict the development of bile leaks in hepatic trauma. This HIPAA-compliant retrospective study was IRB approved and consent was waived. All patients who sustained hepatic trauma between January 1, 2006, and January 31, 2012, and who underwent CT and hepatobiliary scans during the same hospital admission were included. One hundred and thirty-two patients met the inclusion criteria. Comparison between the presence of biliary injury relative to American Association for the Surgery of Trauma (AAST) hepatic injury grade and mean distance of the hepatic laceration to the inferior vena cava (IVC) was made. The ability of free fluid to predict bile injury was analyzed. Forty-one (31 %) of the 132 patients had positive hepatobiliary scans. Of these 41 patients, seven (17 %) sustained low-grade and 34 (83 %) sustained high-grade hepatic injury compared with the 37 (41 %) low-grade and 54 (59 %) high-grade hepatic injuries in the negative hepatobiliary scan group. The mean distance to the IVC was 2.4 cm (SD 2.9 cm) and 3.6 cm (SD 3.3 cm) in patients with and without bile leaks, respectively. A statistically significant difference in the proportion of high-grade injuries and the mean distance from the IVC between the two groups was identified. The presence of free fluid on CT is sensitive, but not specific, for detecting a bile leak. CT findings, including AAST liver injury grade and location of the liver laceration, are able to predict which patients are at risk for developing bile leaks as seen on hepatobiliary scintigraphy, whereas the presence of free fluid is not.

Efficacy of US-guided percutaneous cholecystocholangiography for the early exclusion and type determination of biliary atresia.
    Radiology, 2011, Volume: 261, Issue:3

    To evaluate the efficacy of ultrasonographically (US)-guided percutaneous cholecystocholangiography (PCC) for early diagnosis and characterization of biliary atresia in infants with cholestatic liver disease.. Institutional review board approval was obtained for this study. Parental informed written consent was obtained. From October 2003 to August 2010, 22 infants (12 male, 10 female; age range, 1-138 days) were referred to the radiology department for PCC. Indications for PCC were suspected biliary atresia at 24-hour delayed technetium 99m-diisopropyl-phenylcarbamoylmethyl-iminodiacetic acid (DISIDA) scintigraphy because no excretion was observed in the small bowel (n = 17) or when the results of the scan or liver biopsy could not be obtained within 3 days because of a delay in schedule (n = 5). A diagnosis of biliary atresia was excluded when there was contrast material visualized in the gallbladder, biliary system, and passage to the duodenum. Patients with biliary atresia underwent surgery as the reference standard.. Among the 18 patients who underwent successful PCC, biliary atresia was excluded in 13, with diagnoses as follows: total parenteral nutrition-associated cholestasis (TPNAC) (n = 6), neonatal hepatitis (n = 4), congenital syphilis (n = 1), neonatal lupus (n = 1), and congenital cytomegalovirus hepatitis (n = 1). Biliary atresia was diagnosed in five patients (four with type IIIb and one with type IIIa) and was confirmed at surgery. In four infants in whom US-guided gallbladder puncture had failed, biliary atresia (n = 2) and TPNAC (n = 2) were diagnosed.. PCC is a safe and useful technique for early exclusion when biliary atresia cannot be ruled out after traditional screening tests; in addition, it may be useful for preoperative type determination of biliary atresia. © RSNA, 2011.
