Selective distal splenorenal shunt without requiring splenopancreatic disconnection with the use of the external iliac vein graft: a preliminary report.

BACKGROUND

Distal splenorenal shunt (DSRS) with splenopancreatic disconnection (SPD) is an ideal operation for permanent control of variceal bleeding. However, it is a very complicated procedure, and DSRS without SPD has a functional disadvantage: It gradually loses its selectivity and portal blood flow. To overcome these conditions, we designed a new technique--modified DSRS, which is easy to perform and maintains long-term selectivity of the shunt.

METHODS

Modified DSRS was performed by using an external iliac vein graft without treating small pancreatic tributaries of the splenic vein. It was applied in 4 cases, and shunt patency and selectivity were examined by angiography during follow-up periods (6-76 months).

RESULTS

Modified DSRS was technically more feasible and less complicated than DSRS with SPD. Every attempt was successful. There was no operative mortality, and all the patients were discharged from the hospital in good condition. The shunts were patent in all of them, and the selectivity of the shunt was maintained better in comparison to standard DSRS.

CONCLUSIONS

Modified DSRS is a much easier and safer technique than standard DSRS. We consider this procedure to be the best method for surgical management of portal hypertension causing esophageal and gastric varices.
