Selective and nonselective shunts for variceal bleeding. A prospective study of 103 patients

Based on the experience reported herein, the following conclusions have been made: (1) Although nonoperative means, including sclerotherapy, have an important role in the management of bleeding varices, they are not definitive means of treating recurrent variceal hemorrhage. (2) Because of the maintenance of hepatopetal flow and splanchnic venous hypertension, a selective shunt is associated with a lower incidence of encephalopathy and provides a better quality of life than does a nonselective shunt. Thus, an elective distal splenorenal shunt is the elective operation of choice for recurrent variceal hemorrhage. (3) Nonselective shunts can be performed with similar expectation of patient survival as selective shunts, but because of increased encephalopathy, should be reserved for emergency operations, in cases of unsuitable venous anatomy, and in those patients with intractable ascites. (4) A well-conceived elective shunt procedure can be performed with low operative mortality and long-term patency, results in significant survival, and is still considered the "gold standard" for treatment of variceal bleeding.
