Abstract:
Objective To evaluate the effects,hemodynamies and hepatic functional reserve of a combined procedure of modified pmximal splenocaval shunt and pericardial devascularlzation (PCDV) in the treatment of portal hypertension.Methods From 1997 to 2007,a total of 255 patients with cirrhotic portal hypertension received combined (135 cases) or PCDV procedure (120 cases,) in our hospital.The clinical results were retrospectively analyzed.Changes of hemodynamics of the portal venous system were studied by Doppler color flow imaging and intraoperative free portal pressure (FPP) measurement.The hepatic functional reserve was evaluated by indocyanine green (ICG) retention ratio and functional hepatic flow(FHF).Results Postoperative mortality was 2.2% in combined group and 4.3% in PCDV group.The long term rebleeding rate was 5.5%as revealed by follow-up in combined group,which was significantly lower than that in PCDV group of 14.1%(P<0.05).The incidence of encephalopathy was 6.4%and 5.4%in combined group and PCDV group respectively(P>0.05).The 1-,3-,5-and 10 year-survival rates were 96.4%,90.0%,81.3%and 62.5% in combined group and 95.7%,86.7%,75.0%,57.1%in PCDV group.In combined group,the FPP、PVF and FHFwere(32.0±1.5)cm H_2O、(880±260)ml/min and(430±1 80)ml/min respectively,a significant decrease when compared with preoperative parameters (P<0.05),while R_(15) (30%±4%)increased (P<0.01).The similar results were observed in PCDV group postoperatively (P<0.05).Compared to PCDV group,the decrease of FPP in combined group was more significant(P<0.05),but the PVF,FHF and R_(15) were not significantly different (P>0.05).Conclusions The combined procedure is safe and effective in treatment of portal hypertension with better clinical outcome,moderate homodynamic changes and good maintenance of hepatic functional reserve.
