The study of portal pressure during surgical exploration for biliary atresia in the series of 260 children operated at the Hospital Saint-Vincent de Paul since 1968 showed that portal hypertension could be demonstrated in 61.8% of the cases before the age of 3 months. Among the 54 children surviving without jaundice, splenomegaly was found in 35 cases; esophageal varices were seen in 14 children, more frequently after 5 years of age. Bleeding from esophageal varices occurred only in cases with recurrence of jaundice or moderate biliary retention, i.e. for 6 children. A portocaval shunt was constructed in 7 cases; all had bled except one. One child died two and a half years later from pneumococcal sepsis after a splenorenal shunt with splenectomy; another child had numerous recurrence of bleeding episodes. Five children have a functional shunt and have not rebled. When biliary atresia is cured by hepatoportoenterostomy, with complete disappearance of biliary retention, the risk of bleeding from esophageal varices is unlikely, in spite of persistent cirrhotic alterations of the liver; in these children, there should very seldom be an indication for a portocaval shunt.

The central function of the liver as place of the formation of the most plasmatic coagulation factors in expressed by coagulation disturbances in severe liver diseases. Apart for intoxications, vitamin-K-deficiency and relatively rare congenital dysproteinoses the synthesis of the coagulation factors is apparently a relatively stable and rapidly recoverable function of the hepatocyte. On the other hand, however, the pathogenetic dominance of the accelerated balance in the sense of a disseminated intravasal coagulation and a secondarily increased fibrinolysis is emphasized for the severe disturbances of haemostasis in hepatopathies. In all kinds of shock, in tumours, inflammations, sepsis and intoxications as well as in portal hypertension of any reason the activation of the coagulation system up to the consumption coagulopathy develops. In the liver transplantation in addition to the operation shock deterioratingly comes the intensive blood contact with the often heavily damaged graft cells, the effectors of the immune system (rejection), the temporary disturbance of the clearance function of the liver RES and the basic disease of the recipient which in most cases disposes to the disseminated intravasal coagulation. The reduction of thrombocytes and coagulation factors extensively transgresses the changes which are to be expected by a weakness of the synthesis during and immediately after the anhepatic phase. For the therapy the demand of rapid removal of the coagulation-activating moments (minimum times of ischaemia, careful anastomoses) and of an adequate substitution with simultaneous prevention of the disseminated intravasal coagulation by heparinisation.

161 children followed up postoperatively following splenectomy, 29% had spherocytosis, 14% Hodgkin's disease, 12% traumatic rupture of the spleen, 11% portal hypertension and 7% idiopathic thrombocytopenia. Postoperatively a slight wound infection occurred in 5% of the children, while complications were seen in 2% which could be interpreted as directly caused by the operation; in 23 patients, however, (i.e. 15%), severely infections occurred such as pneumonia, meningitis and sepsis. The lethality rate of the infected children was 31.8%. Postoperatively we determined the leucocyte count, thrombocytes and erythrocyte count, the immunoglobulins IgG, IgA, IgM and IgE, the serum concentrations of the complement components C3, C4 and the serum proteins alpha 1-antitrypsin and transferrin. The data obtained were compared with the corresponding data reported in the literature.

From 1959 until 1981, 157 children were treated for portal hypertension by esophageal varices ligation in 13 cases and by portosystemic shunt in 144 cases. The age of the patients at operation was correlated with the cause of portal hypertension : mean age was six and a half years for cases with extra-hepatic blockage, and ten years for cases with cirrhosis. In 73% of cases, the shunt was undertaken following a bleeding episode from esophageal varices; at the present time, the decision to undertake a prophylactic type of shunt would be much more questionable. Central splenorenal shunt and mesocaval shunt were the operations most frequently performed by the different surgical teams in charge of these children (respectively 69 and 47 cases). Among the postoperative complications, three cases of venous stasis in lower limbs occurred after a mesocaval shunt; one child died two and a half years after a central splenorenal shunt from pneumococcal sepsis. During the last two years, there is a tendency in our group to perform a Warren shunt for intrahepatic portal hypertension, and a mesocaval shunt with jugular vein interposition in the case of extrahepatic portal hypertension. Recurrence of bleeding from esophageal varices after simple ligation has been observed in 64% of the cases; after portosystemic shunts, the anastomosis was a success in 89.3% of the cases. Whereas a significant fall in portal pressure after completion of the anastomosis is of good prognostic value, the fact that in some cases intraoperative measurement of pressure before and after shunting may show no difference does not imply a secondary thrombosis of the anastomosis, since this complication was seen in only 13% of the cases in these conditions.

Five cases of hepatic haemangioma are described, and a sixth (previously reported) is reviewed. Clinical features, investigation, and management are described to show the great variability of the complications and prognosis. Five children presented in the first 10 weeks of life with hepatomegaly; 4 developed congestive cardiac failure; 3 had cutaneous haemangiomata. One child presented at age 4 years with hepatomegaly and anaemia, and on investigation had features of chronic disseminated intravascular coagulation. Focal decrease or patchiness in hepatic uptake of technetium-99m colloid, and abnormal intrahepatic circulation was shown in all cases. In 3 children liver biopsy was performed to exclude malignant disease. In one patient there was spontaneous regression of the tumour by age 3 years. In 3 cases hepatic artery ligation was necessary to control congestive cardiac failure which had persisted despite treatment with digoxin, diuretics, and oral corticosteroids, a procedure which was without complications after up to 8 years. One infant with intractable portal hypertension, hepatic vein obstruction, and severe cholestasis died with persisting alimentary haemorrhage and intra-abdominal sepsis. One child aged 4 years showed no immediate response to hepatic artery ligation but the size of her tumour got smaller and the clinical features diminished after irradiation. These tumours cause considerable morbidity and have a high reported mortality. If congestive cardiac failure is not rapidly controlled, hepatic artery ligation should be performed.

Although liver biopsy is a very useful procedure used frequently in the diagnosis and management of liver dysfunction occurring after orthotopic liver transplantation, complications can occur with its use. An unusual complication of arterioportal fistula is reported here. Based upon this small series of an unusual event and the knowledge that the posttransplant liver may be more hypervascular than prior to OLTx and that it is uniquely susceptible to hepatic infarction and abscess formation, any attempt at fistula closure should be considered carefully prior to initiating the therapy (15). Unless a serious complication occurs [such as a transient biliary obstruction due to hemobilia as occurred in case 2, portal hypertension as also occurred in case 2, or systemic sepsis or other symptoms develop related directly to the fistula], simple observation may be the best choice of action. Should therapy be required, hepatic arterial embolization should be reserved for adults with intrahepatic fistulas. Primary surgical closure of intrahepatic fistula should be reserved for cases of extrahepatic fistula.

The optimal treatment of Budd-Chiari syndrome (BCS) remains an open question. It is still a matter of controversial discussion whether venous decompression or liver transplantation is superior. To elucidate the role and prognosis of both surgical options in our own experience, a consecutive series of 50 patients treated between 1981 and 1993 was retrospectively analyzed. Twelve patients had different types of portosystemic shunts or local decompressive procedures, and transplantation was performed in 43 cases, including five with previous conventional surgery. The overall mortality of 18 of 50 was conventional surgery. The overall mortality of 18 of 50 was concentrated within the early postoperative period, with no patient lost after 1 year. In the venous decompression group, the success rate was only 29%, and treatment failure was closely related to the finding of cirrhosis or technical problems like vascular thrombosis. After transplantation, early complications were rejection, primary nonfunction, or graft necrosis, and contributed significantly to the risk of sepsis. Thirty of 43 liver recipients are currently alive, including four rescued after failed decompressive surgery, with 1- and 10-year survival of 69%, and excellent recurrence-free rehabilitation. These results clearly indicate that patient selection plays a dominant prognostic role in the treatment of BCS. Venous decompression and liver transplantation should both be integrated in a common therapeutic concept, and the individual decision for the preferred approach must be based on the leading clinical symptom: portal hypertension or liver failure, together with the assessment of reversibility of hepatic damage, and the potential of cure of the underlying disease.

The TIPS (transjugular intrahepatic portosystemic shunt) procedure is a relatively new therapeutic treatment option for variceal bleeding secondary to portal hypertension. The TIPS procedure evolved in response to the need for a safe, nonoperative shunting procedure, and is becoming a practical alternative to surgically placed shunts. Possible complications of a TIPS include hemorrhage, postprocedure sepsis, shunt encephalopathy or decompensation. Development of shunt stenosis or occlusion is associated with re-bleeding. Three children (ages 10-13) with recurrent, significant variceal bleeding were referred for the TIPS procedure. Two had recurrent GI hemorrhage despite sclerotherapy. To date, all have maintained shunt patency for up to 1 year. None of these children have had significant re-bleeding episodes, and the only recurrence of varices was associated with an obstructed shunt. In this article, the author reviews both conventional treatment and the TIPS procedure for the child with bleeding varices. Nursing implications from a pediatric perspective are emphasized. Pediatric GI nurses must understand TIPS in order to prepare the child and family and to monitor for complications or shunt failure afterward.

Life-threatening portal hypertension (PHN) in patients with chronic myeloproliferative disorders may result from increased portal flow caused by marked splenomegaly or an increased resistance to portal flow from either a large vein thrombosis or an intrahepatic obstruction usually associated with agnogenic myeloid metaplasia (AMM). The former cause is correctable by splenectomy alone, whereas the latter requires portal-systemic shunt surgery. Few data exist regarding the outcome of portal-systemic shunt surgery in patients with AMM and intrahepatic obstruction. During the past 25 years, 13 patients with chronic myeloproliferative disorders underwent portal-systemic shunt surgery at our institution. The cause of PHN was intrahepatic obstruction in ten patients and hepatic vein thrombosis in three. Ten of the thirteen patients had AMM as initial diagnosis. Only one patient had intraoperative complications, and four patients had either sepsis or thrombosis during the postoperative period. Twelve patients survived the postoperative period and had a median postsurgical survival of 3 years (range, 0.25 to 19 years). The long-term complications of the operation were very few and included hepatic encephalopathy (one patient), portal vein thrombosis (one patient), and shunt occlusion (one patient). The procedure was successful in alleviating complications of PHN in all but one patient. Deterioration of hepatic function and subsequent hepatomegaly were unusual. Portal-systemic shunt surgery seems to be a useful option in patients with AMM and life-threatening PHN from intrahepatic obstruction.

Hypersplenism is defined as the association of anemia, leukopenia, or thrombocytopenia with bone marrow hyperplasia and splenomegaly. Hypersplenism is common in liver cirrhosis and frequent in patients with portal hypertension. The effects of portacaval shunt are variable; hypersplenism hardly ever improves but rarely develops after surgery. Since the spleen is a major component of the mononuclear phagocyte system, splenectomy reduces antibody synthesis. Although splenectomy abolishes hypersplenism, it may lead to sepsis. Recently, partial splenic embolization, using gelform injected directly into the splenic artery, has been performed in patients with cirrhosis. Partial splenic embolization induces an increase in the number of circulating blood cells. In addition, the levels of albumin, hepaplastintest, cholesterol and cholinesterase are increased significantly after treatment. Partial splenic embolization rarely causes problems and may actually be beneficial.
