Título : Biliary Complications Post Transjugular Intrahepatic Portosystemic Shunt in a Child With Portal Vein Cavernous Transformation Tipo de documento : documento electrónico Autores : José Miguel Hidalgo Oviedo, Autor ; Lopera Valle, Johan Sebastián, Autor ; Muñoz Caicedo, Brayan, Autor ; Muñoz Durán, Julián A., Autor Fecha de publicación : 2024 Títulos uniformes : Cureus Idioma : Inglés (eng) Resumen : The transjugular intrahepatic portosystemic shunt is a rising interventional procedure with multiple indications and high technical success but with risks of biliary injuries, an underreported scenario. We present an 11-year-old patient with biliary injury with a leak, biloma formation, and biliary obstruction caused by the percutaneous procedure. Interventional radiology drainages addressed these complications by resolving the leak and biloma. These biliary complications in percutaneous procedures and their management are rarely reported in the medical literature, making their management not standard. We highlight drainage management and the importance of sharing it to add experience to this clinical scenario and encourage sharing cases with similar diagnoses. Mención de responsabilidad : Johan S.

Título : Gadoxetic Acid in MRI: A Five-Year Experience at a High-Complexity Hospital in Colombia Tipo de documento : documento electrónico Autores : Vanessa García Gómez, Autor ; Pimiento Figueroa, Jonathan, Autor ; Lopera Valle, Johan Sebastián, Autor ; Gómez Urrego, Ana M., Autor ; González, Mateo, Autor ; Huertas Duran, Claudia, Autor Fecha de publicación : 2024 Títulos uniformes : Cureus Idioma : Inglés (eng) Palabras clave : adenoma; bile ducts; contrast media; focal nodular hyperplasia; liver cell; liver diseases; magnetic resonance imaging. Resumen : Objective The objective of the study was to evaluate the use of the hepatospecific contrast agent, gadoxetic acid, for MRI in patients at a high-complexity hospital in Medellin, Colombia, from 2016 to 2022. Materials and methods This was an observational, descriptive, and retrospective cross-sectional study involving patients who had undergone MRI with gadoxetic acid from February 2016 to January 2022. The MRI studies were interpreted by two radiologists specializing in body imaging, each with at least 10 years of experience. The medical records of the identified patients were reviewed. Quantitative variables were presented using either means and standard deviations or medians and interquartile ranges, depending on the distribution of the variables. Qualitative variables were represented through absolute and relative frequencies. Results A total of 100 pharmacy records were collected, leading to a final sample of 75 patients aged between three and 91 years. The primary reason for imaging was to assess focal liver lesions in 58 patients (77.3%), with bile duct injury being the second most common indication in 16 patients (21.3%). A diagnostic alteration was noted in 69.3% of cases (52 patients). Among the 58 focal liver lesions analyzed using a hepatospecific agent, 31 cases (53.4%) were diagnosed as focal nodular hyperplasia. Conclusion Our study reinforces the clinical value of gadoxetic acid-enhanced MRI in refining diagnostic assessments, particularly in cases involving bile duct and focal hepatic lesions.

Título : Magnetic Resonance Cholangiography Diagnosing Post-cholecystectomy Biliary Injuries Tipo de documento : documento electrónico Autores : Vanessa García Gómez, Autor ; Florez Leguia, Maria Katherine, Autor ; Muñoz Caicedo, Brayan, Autor ; Lopera Valle, Johan Sebastián, Autor ; Noreña Rengifo, Brian, Autor ; Arroyave Toro, Astrid, Autor Fecha de publicación : 2024 Títulos uniformes : Cureus Idioma : Inglés (eng) Resumen : Objective: This study aimed to determine the diagnostic performance of contrasted magnetic resonance cholangiography for detecting bile duct lesions following cholecystectomy. Materials and methods: A retrospective case series study was conducted that included patients over 18 years of age with suspected bile duct injury after cholecystectomy, who underwent contrasted magnetic resonance cholangiography, and who also had endoscopic retrograde cholangiopancreatography, surgery, or subsequent clinical follow-up. The images were interpreted by two radiologists who assigned the type of lesion according to the Strasberg classification. Qualitative variables were represented by frequencies and proportions, while quantitative variables were described using measures of central tendency and dispersion. Sensitivity, specificity, and predictive values were assessed, along with interobserver variability, using the kappa index. Results: We included 20 patients with a median age of 51.5 years (interquartile range: 35), and 14 (70%) were women. In all 20 patients, lesions were identified on magnetic resonance cholangiography, of which 19 were confirmed with the gold standard for a positive predictive value of 100% (hepatobiliary-specific contrast agents) and 92% (extracellular contrast). The most frequent lesions were Strasberg E2 and E4 in five patients each. The kappa index was 1 in determining the presence or absence of bile duct injury and 0.9 in the Strasberg classification. Conclusion: Contrasted magnetic resonance cholangiography is a method with high positive predictive value and almost perfect interobserver agreement for diagnosing bile duct lesions after cholecystectomy.
