ABSTRACT
El traumatismo pancreático es una entidad poco frecuente pero potencialmente mortal, del que es necesario un alto nivel de sospecha clínica. El diagnóstico precoz y la valoración de la integridad del conducto pancreático son relevantes, siendo la lesión ductal el principal predictor de morbimortalidad. La mortalidad global es del 19%, ascendiendo al 30% en presencia de compromiso ductal. El abordaje diagnóstico y terapéutico es multidisciplinario (médico cirujano, radiólogo e intensivista). La analítica de laboratorio muestra elevación de las enzimas pancreáticas, siendo este hallazgo de baja especificidad. En pacientes con hemodinamia estable, la primera aproximación diagnóstica debe ser con una tomografía computarizada multidetector con contraste, recurriendo a la colangiopancreatografía endoscópica retrógrada o a la colangiorresonancia en caso de sospecha de lesión ductal. El propósito de esta revisión es analizar la etiopatogenia y fisiopatología del traumatismo pancreático, presentando su abordaje diagnóstico y terapéutico y sus complicaciones más frecuentes (AU)
Pancreatic trauma is a rare but potentially lethal entity which requires a high level of clinical suspicion. Early diagnosis and assessment of the integrity of the pancreatic duct are essential since ductal injury is a crucial predictor of morbimortality. Overall mortality is 19%, which can rise to 30% in cases of ductal injury. The diagnostic and therapeutic approach is multidisciplinary and guided by a surgeon, imaging specialist and ICU physician. Laboratory analysis shows that pancreatic enzymes are frequently elevated, which is a low specificity finding. In hemodynamically stable patients, the posttraumatic condition of the pancreas is firstly evaluated by the multidetector computed tomography. Moreover, in case of suspicion of ductal injury, more sensitive studies such as Endoscopic Retrograde Cholangiopancreatography or cholangioresonance are needed. This narrative review aims to analyze the etiopathogenesis and pathophysiology of pancreatic trauma and discuss its diagnosis and treatment. Also, the most clinically relevant complications will be summarized (AU)

Monitoring intra-abdominal pressure (IAP) has become a standard in intensive care units. Correlation between the abdominal wall's thickness (AWTh) and IAP has been reported previously. The abdominal wall can be modeled as a compound of parallel dielectric slabs; changes in their width have a direct effect on the reflection coefficient of the abdominal wall at microwave frequencies. This work describes the design of a reflectometry system and its proof-of-concept trial on five patients during laparoscopic surgery. The system complies with IEEE Std. C95.1-2005 concerning exposure of humans to microwave electromagnetic fields in controlled environments. The results putatively show an inverse correlation between IAP and the reflection coefficient, and a strong dependence on the body mass index. A better understanding of the dynamics in the changes of the AWTh (during intra-abdominal hypertension) will allow further development of a microwave-based technique for the continuous non-invasive indirect monitoring of IAP in critical patients.
