title: Splenic arterial ligation prevents liver injury after a major hepatectomy by a reduction of surplus portal hypertension in hepatocellular carcinoma patients with cirrhosis.
abstract: OBJECTIVE
  In this study, we investigated whether a reduction of surplus portal hypertension after a major hepatectomy by SPL (splenic arterial ligation) prevents a liver injury in cirrhotic patients with hepatocellular carcinoma.
  
  
  METHODS
  Six hepatocellular carcinoma patients (SPL group) with liver cirrhosis (67 +/- 10 years old, ICGR15: 21.0 +/- 9.8%, T.Bil: 1.1 +/- 1.2 mg/dL) underwent major hepatectomy with splenic arterial ligation in order to reduce excessive portal hypertension after hepatectomy from 1998 to 2000, July. The patients (n = 15, 60 +/- 9 years old, ICGR15: 11.5 +/- 5.9%, T.Bil: 0.66 +/- 0.15 mg/dL) who underwent liver resection above subsegmentectomy in the same period (control group) served as the control for SPL group.
  
  
  RESULTS
  In the SPL group, the portal pressures before hepatectomy were 26 +/- 7 cm H2O and those after hepatectomy were 29 +/- 6 cm H2O. The portal pressure after splenic arterial ligation decreased to 24.5 +/- 6.3 cm H2O. The splenic tissue blood flows before SPL were 16.8 +/- 5.6 mL/min/100 g, while those after SPL were 7.2 +/- 2.2 mL/min/100 g. The portal pressures before hepatectomy were 17 +/- 2 cm H2O and those after hepatectomy were 19 +/- 2 cm H2O in the six control patients. At the peak levels of liver function after surgery, T.Bil was 2.6 +/- 1.5 mg/dL, GOT was 165 +/- 59 IU/L, and GPT was 107 +/- 49 IU/L. All patients could discharge without complications except for one case with bile leakage in SPL. At the peak levels of liver function in control group, T.Bil was 3.7 +/- 1.9 mg/dL, GOT was 404 +/- 227 IU/L, and GPT was 322 +/- 171 IU/L. At the peak levels of liver function after surgery, T.Bil was 3.4 +/- 1.3 mg/dL, GOT was 398 +/- 289 IU/L, and GPT was 319 +/- 220 IU/L. Conversely, there were 11 episodes of complications (11/15), including two cases of hospital death resulting from liver failure in patients who underwent right lobectomy, in the control patients.
  
  
  CONCLUSIONS
  The decompression of surplus portal hypertension by SPL might be effective in the prevention of post hepatectomized liver injury and the improvement of postoperative mortality and morbidity.
