BACKGROUND Liver transplantation is performed at large transplant centers worldwide as a therapeutic intervention for patients with end-stage liver diseases. AIM To analyze the outcomes and incidence of liver transplantation performed at the University of São Paulo and to compare those with the State of São Paulo before and after adoption of the Model for(More)
BACKGROUND Hepatopulmonary syndrome is formed by a triad of liver disease, intrapulmonary vascular dilatation and changes in blood gases. This condition is present in 4-32% of patients with cirrhosis. AIM To analyze the blood gas changes data of patients in liver-transplant waiting list. METHOD Clinical data of 279 patients in liver transplantation(More)
Alimentary tract duplications are rare congenital malformations that may be found anywhere from mouth to anus. They usually share a common smooth muscle wall and blood supply with the adjacent bowel. Some duplications are asymptomatic but most cause problems in early childhood. Gastric duplications account for 2% to 7% of all gastrointestinal duplications.(More)
A case of cystic dilation isolated from the cystic duct is described. The patient showed symptoms of chronic calculous cholecystitis; the ultrasonographic examination confirmed the clinical hypothesis and showed a 1.3-cm calculus impacted in the infundibulum of the gallbladder. The hepatic and biliary functions were normal. During surgery, the routine(More)
INTRODUCTION Variations on the anatomy of the hepatic artery are common, with incidence of 20-50%. In liver transplantation, back-table reconstruction is often necessary for an easier and prompt arterial anastomosis and so, the use of arterial patches has been related to lower the incidence of complications. However, when a right hepatic artery variation(More)
AIM To simulate a hypothetical increase of 50% in the number of pancreas-kidney (PK) transplantations using less-than-ideal donors by a mathematical model. METHODS We projected the size of the waiting list by taking into account the incidence of new patients per year, the number of PK transplantations carried out in the year and the number of patients who(More)
BACKGROUND Small intestine transplantation has been accepted worldwide to treat complex cases of intestinal failure. Canine intestinal transplantation model is important in training the surgical technique and to study the complications of this procedure. Systemic graft venous drainage is frequently performed in clinic, although the consequences of this(More)
BACKGROUND Portal vein thrombosis was considered a contraindication for liver transplantation in the past because of the high morbidity and mortality rates. Many advances made the results better. AIM Review the advances and surgical strategies for liver transplantation in presence of portal vein thrombosis. METHOD Survey of publications in Medline,(More)
Jejunostomy is widely acknowledged in the literature as a means for enteral nutrition. Complication rates range from 16% to 46% for the classical open technique and from 11% to 70% for the several mini-invasive techniques currently in use, including the laparoscopic techniques. The most probable complications are abscess, intestinal obstruction, abdominal(More)
BACKGROUND Pseudoaneurysm is a rare vascular complication in pancreas transplantation. This complication develops from a disruption of the arterial continuity, usually related to trauma, infection, vasculitis, or complications in vascular procedures. CASE REPORT A 43-year-old man underwent simultaneous pancreas and kidney transplantation for end-stage renal(More)
