title: The evolution of portal hypertension surgery: lessons from 1000 operations and 50 Years' experience.
abstract: OBJECTIVE
  Surgery for portal hypertension has evolved widely in the past decades. Selection criteria and the type of operations have evolved because of the appearance of other therapeutic alternatives, such as pharmacotherapy, endoscopic therapy, transjugular intrahepatic portosystemic shunt, and liver transplantation. We believe the surgical approach has a therapeutic role in a select patient population.
  
  
  METHODS
  Retrospective review of the medical records of patients operated on for bleeding portal hypertension in the past 50 years.
  
  
  METHODS
  An academic tertiary care university hospital.
  
  
  METHODS
  In a 50-year period, 1000 operations for the treatment of bleeding portal hypertension have been done, including shunts and devascularization procedures. In the past years, in low-risk (Child-Pugh classification A) selected patients, only portal blood flow-preserving operations have been done.
  
  
  RESULTS
  Non-portal blood flow-preserving procedures had a wide spectrum of results, with a high encephalopathy rate and short long-term survival. The results with portal blood flow-preserving procedures in the past 10 years are as follows: operative mortality, 2.7%; postoperative encephalopathy, 6%; rebleeding, 6%; and shunt obstruction, 4%.
  
  
  CONCLUSIONS
  Portal hypertension surgery has a role in elective operations and in low-risk selected patients, when portal blood flow-preserving procedures are done. The type of operation is selected according to the individual characteristics of each patient.
