Selective decongestive devascularization shunt of gastrosplenic region for treatment of portal hypertension

Abstract

Objective To evaluate the curative effect of selective decongestive devascularization shunt of gastrosplenic region(SDDS-GSR) for the treatment of portal hypertension. Methods From September 2000 to June 2008, 44 patients with portal hypertension had received SDDS-GSR in our hospital. Twenty-nine of them had been followed up for 12-85 months (mean=44months). Results Operative mortality was 0 %. Mesenteric area pressure(33.82±5.12 cm H_2O) was higher than splenic area pressure(24.57±4.63 cm H_2O)soon after the operation finished(P<0.01). No re-bleeding ca-ses were found, and the encephalopathy occurred in 2.27% of the patients in the early stage of post-operation. However, the rates of 3.45% for re-bleeding and 3.45% for encephalopathy were noticed in long-term follow-up. The 1-, 3- and 5-year survival were 100%, 95% and 95%, respectively. Dur-ing the long-term follow-up, the platelet counts markedly increased from (49.2±21.8 × 10~9/L) of preoperative value to (77.2±29.5×10~9/L) (P<0.01), while spleen size was significantly reduced.Conclusion SDDS-GSR is a reliable and reasonable surgical procedure for the management of portal hypertension.
