In all, 196 children received liver transplants; 40 of them (20 boys and 20 girls; median age of 4 years) were treated using PTC due to biliary complications. Sixty-one PTC procedures were performed in 40 liver transplant recipients. Technically successful PTC was achieved in 87.5% of the patients. The probability of a patient not developing unfavorable outcomes 1, 5, and 10 years after treatment was 88.9%, 83.0%, and 74.1%.
Bariatric surgery has proven to be the most effective weight loss strategy in severe obesity. Imaging in the immediate postoperative period of bariatric surgery is not done routinely. However, it is helpful in the assessment of early and late complications, which are estimated to be present in < 1% of patients. In some cases, the imaging interpretation of anatomical outcomes and complications related to these procedures represents a challenge for surgeons and radiologists. The aim of this review is to describe the imagenologic findings after bariatric surgery and focuses on the findings of the most frequent procedures performed in Colombia such as laparoscopic sleeve gastrectomy, laparoscopic Roux-en-Y gastric bypass, and laparoscopic adjustable gastric banding. Contrasted CT scan and fluoroscopic studies have shown a high sensitivity in the early and late diagnosis of bariatric surgery complications, but in order to be able to appropriately identify these complications, it is important to be familiar with the normal or expected radiological findings.
Objetivo: Determinar la concordancia entre DWI-RM en pacientes con sospecha decolesteatoma y los hallazgos en cirugía y patología. Diseño: Estudio observacionalde corte transversal. Métodos: Se revisaron DWI-RM de pacientes con sospechaclínica de colesteatoma realizadas en la Fundación Valle de Lili entre Enero del2012 y Noviembre del 2015 quienes fueron llevados a cirugía comparando loshallazgos obtenidos en la RM y en la patología. Resultados: Se evaluaron 15 DWIRMde pacientes con sospecha de colesteatoma llevados a cirugía, 8 mujeres y 7hombres entre 6 y 72 años. Se concluyeron 6 estudios positivos y 9 sin evidencia decolesteatoma. Todos los pacientes del grupo con RM positiva fueron confirmadospor patología. En total, hubo una concordancia diagnóstica casi perfecta (Kappa:0,86 IC 95% 0,65-1). Conclusión: La DWI-RM es específica para la detección decolesteatoma y es una herramienta útil en el seguimiento y planeamiento quirúrgico.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
