RESUMO

Dr Dean Warren was born in 1924 and died prematurely from cancer in 1989. He was a man of uncommon intelligence, wit, collegiality, integrity, honesty, and a true leader in American surgery. In 1966, he and his colleagues (Drs Zeppa and Fomon) presented a new concept for surgical shunts to control variceal hemorrhage while maintaining portal perfusion or hepatopetal blood flow. He termed this new shunt the distal splenorenal shunt (DSRS), which was the first selective shunt invented. The DSRS selective shunt was a brilliant improvement over the total shunt concept proposed by Nicolai Eck and was practiced worldwide during the 1980s. In a space of 2 decades, Dr Warren's pioneering work would show that the selective DSRS was superior to total shunts for treatment of portal hypertension, but that endoscopic sclerotherapy was a better first-line treatment for variceal hemorrhage than his own creation. His absolute adherence to the principles he espoused in his presidential address to the Society for Surgery of the Alimentary Tract in 1973 were employed in his research and treatment of patients. This paper details Dr Warren's extraordinary research accomplishments and sets a lesson for us that well-designed clinical trials including randomization are essential in the advancement of the care of surgical patients.
