N. Nagasue et al., Role of splenectomy in hepatic resection for hepatocellular carcinoma associated with severe cirrhosis and hypersplenism, HEPATOL RES, 14(1), 1999, pp. 35-48
The incidence of hepatocellular carcinoma (HCC) associated with severe cirr
hosis has been increasing due to better management of chronic liver disease
. This study prospectively aimed to elucidate whether splenectomy is benefi
cial or detrimental when performed simultaneously with hepatic resection in
patients with HCC and hypersplenism due to severe cirrhosis. Splenectomy a
nd subsequent partial hepatectomy were concomitantly performed on 26 patien
ts with Child-Turcotte class B (n = 17) or C (n = 9) cirrhosis, HCC and hyp
ersplenism. Portal pressure was measured before and after splenectomy in 21
cases. Endothelin-l (ET-1) levels in splenic venous blood were estimated i
n eight cases. The splenectomy reduced portal venous pressure by 20%. The E
T-1 level in splenic venous blood was significantly higher than that in sys
temic blood indicating the release of ET-1 from the spleen into the portal
circulation. Operative morbidity and mortality rates were 23.1 and 11.5%. C
hild's class C was improved to class B or A in half of the patients. The 1-
, 3-, and 5-year survival rates were 61.5, 42.3 and 16.5%. These results we
re compared with those of 36 patients with Child's class B (n=29) or class
C (n=7) cirrhosis and HCC in whom concomitant splenectomy had not been perf
ormed because of weak or no hypersplenism. The extent of hypersplenism and
hepatic dysfunction was more severe and the estimated blood loss during sur
gery was larger in the splenectomy group. Despite such background differenc
es, there were no significant differences between the two groups in postope
rative morbidity and mortality rates, causes of late death, and long-term s
urvival rate. Concomitant splenectomy during hepatic resection seems to be
beneficial in the treatment of HCC and hypersplenism associated with severe
cirrhosis. (C) 1999 Elsevier Science Ireland Ltd. All rights reserved.
