BACKGROUND Pressure increase in the portal venous system, caused by reduction of blood supply to the liver, develops collateral circulation of splanchnic vessel that reaches the venous system of superior vena cava. The spleen works as an auxiliary capacitance system which compensates the increase in portal pressure that may cause splenomegaly. AIM To(More)
BACKGROUND The calculation of the volume ratio between the hernia sac and the abdominal cavity of incisional hernias is based on tomographic sections as well as the mathematical formula of the volume of the ellipsoid, which allows determining whether this is a giant hernia or there is a "loss of domain". As the images used are not exact geometric figures,(More)
BACKGROUND Adhesions induced by biomaterials experimentally implanted in the abdominal cavity are basically studied by primary repair of different abdominal wall defects or by the correction of incisional hernias previously performed with no precise definition of the most appropriate model. AIM To describe the adhesions which occur after the development(More)
BACKGROUND Ultrasound, computed tomography, and magnetic resonance imaging of abdominal wall has increasingly been used for hernia diagnosis when clinical examination is uncertain. Anatomical study of abdominal wall along with the ultrasound of transversus abdominis muscle aponeurosis can help identify a Spigelian hernia in this region, a disease of(More)
BACKGROUND The negative result of a research does not always indicate failure, and when the data do not permit a proper conclusion, or are contrary to the initial project, should not simply be discarded and archived. AIM To report failure after performing experimental model of liver ischemia and reperfusion normothermic, continuous or intermittent, in(More)
HEADINGS Abdominal wall. Hernia, ventral. Hematopoietic stem cells. Surgical mesh. Adverse effects ABSTRACT Background: Extramedullary hematopoiesis depends on complex pathophysiological mechanisms linked to hematopoietic stem cells and the proteins considered mediators of the inflammation. The identification of hematopoietic cells outside bone marrow in(More)

ABSTRACT Background: Ultrasound, computed tomography, and magnetic resonance imaging of abdominal wall has increasingly been used for hernia diagnosis when clinical examination is uncertain.

BACKGROUND Partial portal vein ligation causes an increase in portal pressure that remains stable even after the appearance of collateral circulation, with functional adaptation to prolonged decrease in portal blood flow. AIM To assess whether different constriction rates produced by partial ligation of the vein interfere with the results of this(More)
