title: The selective shunt for variceal bleeding: a personal perspective.
abstract: It has been proved that selective decompression of esophageal varices can occur by way of the left gastric venous route or the transsplenic route. The left gastric venacaval shunt functions well over a long postoperative period, if the shunt is technically satisfactory; however, the distal splenorenal shunt (DSRS) can be problematic. Unless the proximal and distal portions of the splenic vein are both entirely isolated from the pancreas, blood flow will be diverted from the portal vein to the distal splenic vein, where the pressure has been lowered by the shunt. This portal malcirculation may lead to portal thrombosis or stenosis on occasion. To prevent this adverse effect, complete isolation of the splenic vein (splenopancreatic disconnection) is necessary. Extensive gastric disconnection is irrelevant in this regard. Although the conventional DSRS has been viewed with disfavor, we must realize that splenopancreatic disconnection makes the DSRS a satisfactory technique. The clinical evidence and theoretic basis of the selective shunt for esophageal varices are described herein.
