The frequency of diseases responsible for non-cirrhotic intrahepatic portal hypertension varies according to the patients' geographical origin. The condition is rare in Europe. These diseases may be classified into two main groups, sometimes intricated: 1) fibrosing diseases due to chronic active hepatitis or to a chronic cholestatic disease (primary biliary cirrhosis, primary sclerosing cholangitis, sarcoidosis, congenital hepatic fibrosis); 2) vascular diseases occluding the portal vein (schistosomiasis, idiopathic portal hypertension, regenerative nodular hyperplasia), the intrahepatic veins (alcoholism, drugs, radiations, toxic substances) or the sinusoids (peliosis, amyloidosis, hypervitaminosis A, blood diseases). The prognosis of these diseases, (apart from that of certain responsible or associated diseases), is better than the prognosis of cirrhosis, since the liver cell functions are normal or little altered for a long time. However, in most cases the treatment of non-cirrhotic intrahepatic portal hypertension is similar to that of cirrhotic portal hypertension.

Several different hepatic parenchymal lesions, including chronic hepatitis and cirrhosis, have been increasingly reported in children with schistosomal hepatic fibrosis (SHF) despite the known mesenchymal nature of the disease. The prevalence of persistent hepatitis (B) surface (HBs) antigenaemia and some hepatic functions have been determined in 52 children with SHF as well as in 100 age-matched healthy children. High prevalence of chronic HBs antigenaemia (58 per cent) has been demonstrated in children with SHF, but only in 2 per cent of the normal children. This denotes that children with SHF represent a dangerous reservoir for hepatitis B infection to the community. Serum alanine transferase (ALT) was higher than normal in 58 per cent of HBS seropositive patients and in none of the seronegative patients. This points to the risk of continual hepatic parenchymal injury to the HBs seropositive patients with schistosomiasis.

In the early 1970s, we began to perform selective shunts on a regular basis for the treatment of portal hypertension. In a 15-year period, 177 patients (155 with liver cirrhosis) were treated with 3 kinds of selective shunts: the Warren shunt (128 patients) the end-to-end splenorenal shunt (29 patients), and the splenocaval shunt (20 patients). One hundred sixty-seven of the procedures were elective. Operative mortality was 14%, and survival for the Child's class A group was 75% at 1 year, 69% at 5 years, and 65% at 15 years. Incapacitating encephalopathy was observed in 7% of the patients, rebleeding in 6%, and shunt thrombosis in 6%. Postoperative portal vein alterations included reduced venous diameter (13%) and thrombosis (21%). Experience with the Warren shunt in schistosomiasis, a disease in which normal liver function is the rule in Latin American countries, is discussed. We believe that, when feasible, the selective shunts are the treatment of choice for portal hypertension in Latin American countries.

Herein we report the results and current status of the distal splenorenal shunt (DSRS) in China. From June 1979 to June 1989, the DSRS was performed in 302 patients with esophagogastric varices. Among a group of 249 patients, 112 were in Child's class A, 97 were in class B, and 40 were in class C. The cause of portal hypertension was posthepatic cirrhosis in 217 patients, schistosomiasis in 28 patients, alcoholic cirrhosis in 3 patients, and biliary cirrhosis in 1 patient. Therapeutic selective shunts were performed in 200 patients with variceal bleeding, and 102 patients received prophylactic shunts. Emergency operations were performed in 10 patients. The original Warren shunt was performed in 264 patients, and various modifications in 38 patients. Simultaneous ligation of the splenic artery was performed in 202 patients. The overall operative mortality rate was 6%. A 3-month to 10-year follow-up demonstrated an 8% recurrent bleeding rate, a 1% incidence of encephalopathy, and a survival rate ranging from 72.3% to 100%. From the preliminary results obtained, we conclude that DSRS is effective and safe in the treatment of esophagogastric variceal bleeding. It can also be used as a prophylactic procedure in Child's class A and B patients.

The hepatic sonographic patterns from 50 patients undergoing operations for bleeding esophageal varices were compared with the interpretation of the histological findings in a hepatic wedge biopsy obtained during surgery. The sonographic pattern for schistosomiasis periportal fibrosis is characteristic and is not mimicked by other hepatic diseases we have studied. Sonography agreed with pathology in 44 out of 50 patients. Schistosomiasis could be separated from cirrhosis, as well as from combined lesions. Where there was a discordance, we believe that sonography gave a more accurate diagnosis.

A morphological, karyometric, and quantitative study of cerebral neuroglia and endothelial cells of blood capillaries was done in cirrhotic and in hepatosplenic schistosomotic human autopsied cases. Cluster analysis applied to them revealed three subgroups (cirrhosis and schistosomiasis polar groups and one intermediate). The comparison of these three groups with a control revealed increased numbers of astrocytes, oligodendrocytes and endothelial cells, but no nuclear enlargement in the schistosomiasis group; the cirrhosis group exhibited a pronounced nuclear enlargement of both astrocyte and oligodendrocytes but no increase in cell numbers. The intermediate group, which encompasses the majority of pathological cases, is heterogeneous but on average behave as the cirrhosis group in that nuclear enlargement, but no increase in cell numbers, was noted. Such changes could represent a response of the nervous system to the metabolic disturbances present in hepatic and/or portal-systemic encephalopathy. There was a positive correlation between glial and endothelial cell numbers in cerebral cortex, suggesting a functional relationship between the glial cells and the capillary bed. This study points out the importance of clustering the cases, because the physiopathological status of individuals belonging to the same nosological condition can be different. Comparisons considering this aspect should be useful in understanding the progression of the pathological process.

The mean values of IgG and IgA were significantly higher in bilharzial patients than in the non bilharzial ones. The mean IgG level in patients with S. mansoni was significantly higher than that in patients with negative stool while the reverse was true as regards IgA. Among the bilharzial patients the mean values of IgG, IgM and IgA were significantly higher in C.A.H. and C.A.H. bilharziasis than in patients with pure bilharziasis, C.P.H. and C.P.H. with bilharziasis. It might be concluded that the altered immune response produced by schistosomiasis, the frequent exposure to the hepatitis B. virus and the bilharzial hepatitis lesions, all may pave the way for development of severe diseases e.g. chronic active hepatitis and liver cirrhosis.

The CT findings of hepatic cirrhosis caused by schistosomiasis Japonica comprise in addition to common manifestations of cirrhosis, the peculiar septal and capsular calcifications resulting in a map-like appearance. In advanced cases, septal fibrotic scar retracts the surface of liver and forms shallow notches, giving rise to pseudolobulated contour. Carcinoma may complicate hepatic schistosomiasis japonica with cirrhosis, but large ova-nodule can mimic cancer on CT image.

Markers of hepatitis A and B virus were tested in 88 adult Sudanese subjects in Khartoum, Sudan. The subjects consisted of 25 control hospitalized patients, 21 volunteer blood donors, 23 patients with hepatosplenic schistosomiasis, 13 patients with liver cirrhosis and 6 patients with hepatocellular carcinoma (HCC). Antibody to hepatitis A virus was detected in 96% of the total. Hepatitis B surface antigen (HBsAg) was positive in 4, 24, 22, 31, and 67% of the subject groups, respectively. Antibody against hepatitis B core antigen (HBcAb) of undiluted serum was positive in 60, 57, 65, 77 and 83%, and there was no difference in incidence among the groups. It was positive in 200X diluted serum in 4, 24, 17, 23 and 60%. HBsAg and HBcAb (200X) were detected more often in HCC patients than in the control subjects (p less than 0.01). Hepatitis B virus is an important factor in the etiology of HCC in the Sudan.

Operative ligation of portosystemic shunts is effective in controlling chronic portosystemic encephalopathy (CPSE) but is associated with significant mortality. Review of the records of five patients with CPSE treated with radiologic occlusion procedures showed that these are suitable alternatives to surgery. Three patients had alcoholic cirrhosis, one had hepatic fibrosis from schistosomiasis, and one had post-necrotic cirrhosis. All had CPSE with progressive, severe cerebral impairment refractory to clinical treatment. Four patients had a spontaneous splenorenal shunt, and one had a surgically created mesocaval shunt (MCS). Partial splenic embolization was performed in two patients, direct shunt embolization was performed via percutaneous transhepatic portography in two other patients, and an MCS embolization was performed in one patient through the inferior vena cava. In four patients embolization controlled the CPSE. In the remaining patient it could not be evaluated because of his premature death from intraabdominal bleeding, a late complication of the procedure. Interventional radiologic procedures are effective in the control of CPSE in selected patients.
