先天性肝纤维化24例临床分析并文献复习

目的分析先天性肝纤维化的临床特征。方法对24例先天性肝纤维化患者临床症状、体征、实验室化验检查及病理学特点进行回顾性分析。结果 24例患者均有门脉高压表现,8例曾有消化道出血。化验肝功能正常或轻度异常。影像学检查提示7例存在肝肾囊肿。22例病理结果均提示先天性肝纤维化,其中9例合并先天性肝内胆管扩张（Caroli’s）病。结论对于病因不明门脉高压,尤其门脉高压与肝功损害程度不一致的患者应尽量行肝组织活检病理检查以协助诊断。先天性肝纤维化与肝肾囊肿、Caroli’s病常常伴发。

Follow up in a case of congenital hepatic fibrosis (author's transl)

A case of congenital hepatic fibrosis (CHF) is described. CHF is characterized by hepatomegaly, portal hypertension, extensive portal fibrosis, ectatic bile ducts, and hypoplasia of terminal portal vein branches. In contrast to the severe portal hypertension liver function tests are largely normal. In our case the disease was first detected when the patient was 7 years old. During the following 9 1/2 years three sequential liver biopsies were performed. Each of them showed the same picture and no progression occurred. The characteristic histological picture of CHF includes mature bile ducts without epithelial proliferation, absence of significant intraportal or interlobular inflammatory infiltrates, and small or hypoplastic distal portal vein branches. On the basis of these features the disease can easily be separated from other forms of liver cirrhosis.     

Liver disease in Felty's syndrome

Eighteen patients with Felty's syndrome were examined prospectively for the presence of hepatic abnormalities. Twelve patients had abnormal liver histologic features: five with nodular regenerative hyperplasia and seven with portal fibrosis or abnormal lobular architecture. Only seven of the 12 had abnormal liver chemistry results. Four of the 12 had portal hypertension, and three bled from esophageal varices compared with one of six with normal histologic features. When patients with normal and abnormal liver histologic findings were compared, there was no difference in clinical, serologic, or extra-articular manifestations between the two groups, although there was a tendency for the patients with abnormal findings to have a higher incidence of vasculopathy. All patients with Felty's syndrome should be screened for hepatic abnormalities and portal hypertension as they have an increased likelihood of bleeding from esophageal varices.     

A case of congenital hepatic fibrosis presented with symptom of acute cholangitis]

Congenital hepatic fibrosis (CHF) is an autosomal recessive disease, presenting principally in children or young adults with portal hypertension, and infrequently associated with cholangitis. It is associated with renal malformation and Caroli's disease. The diagnosis of CHF is usually confirmed by its typical histological features. Cholangitis is a severe and frequently fatal complication. We report a 22-year-old man with congenital hepatic fibrosis who showed the cholangitis without radiological features of cystic dilatation or stone of intrahepatic ducts.     

Is portal vein cavernous transformation a component of congenital hepatic fibrosis？

Congenital hepatic fibrosis （CHF） is an autosomal recessive disorder that belongs to the family of fibropolycystic liver diseases. This family includes a spectrum of disorders which are usually found in combination with each other and are usually inherited. Clinically fibropolycystic diseases have three effects being present in different proportions, those of a space occupying lesion, of portal hypertension and of cholangitis. In most patients, the first manifestations of CHF are signs and symptoms related to portal hypertension such as splenomegaly and varices. Portal hypertension in these patients has been attributed to the hypoplasia or compression of the portal vein radicles in the fibrous bands. Cavernous transformation of the portal vein （CTPV） is a relatively rare condition resulting from extrahepatic portal vein obstruction with recanalization or collateral vein formation to bypass the obstruction. It has been found that patients with CHF having an accompanying CTPV have relatively large splenomegaly and suffers more frequent episodes of bleeding from esophageal varices.We believe that CTPV is a congenital component of CHF and also one of the important causative factors of portal hypertension in these patients.     

Congenital hepatic fibrosis

We report the clinical features of 7 men (mean age 22 years, range 7-53 years) with congenital hepatic fibrosis (CHF). Five patients presented with variceal bleeding and/or hepatosplenomegaly due to portal hypertension. Cholangitis was the presenting symptom in the other 2 cases. Diagnosis was established by histological examination of a surgical wedge biopsy (4 patients) or needle biopsy (3 patients). A portal-systemic shunting was performed in 6 patients, three times prophylactically. None of the 5 survivors developed chronic hepatic encephalopathy. Recurrent bouts of cholangitis with septicemia and hepatic abscesses were a major complication in 5 patients with a fatal outcome in 2 cases. Six patients had associated small and large cysts in the cortex of both kidneys, compatible with adult-type polycystic disease. One patient developed terminal renal insufficiency. In 3 patients kidney function remained normal at a mean follow-up time of 7.5 years (range 1-18 years). In 2 families (4 cases) an autosomal dominant inheritance of renal disease was suggested. This study demonstrates that CHF is a rare cause of portal hypertension in late childhood and in adults. Cholangitis is a severe and frequently fatal complication. Association with a variety of congenital renal abnormalities is very frequent. However, the association with adult-type polycystic disease as reported in 4 cases is very rare.     

Non-cirrhotic portal fibrosis (idiopathic portal hypertension): experience with 151 patients and a review of the literature

BACKGROUND: Non-cirrhotic portal fibrosis (NCPF), the equivalent of idiopathic portal hypertension in Japan and hepatoportal sclerosis in the United States of America, is a common cause of portal hypertension in India. The clinical features, portographic and histological findings, and management of 151 patients with non-cirrhotic portal fibrosis are presented. METHODS: The disease is diagnosed by the presence of unequivocal evidence of portal hypertension in the definite absence of liver cirrhosis and extrahepatic portal vein obstruction (EHPVO). Retrospective analysis of records of 151 patients with NCPF was analyzed for the clinical presentation, physical findings, laboratory tests, radiological and histological findings, and for the outcome of treatment. RESULTS: The disease is characterized by massive splenomegaly with anemia, preserved liver function and benign prognosis in a majority of patients. Splenoportovenography (SPV) showed massive dilatation of the portal and splenic veins, and the presence of collaterals. Twenty-four (15.9%) patients showed evidence of natural/spontaneous shunts (splenorenal 15, umbilical nine) on SPV; these patients had a lower incidence of variceal bleeding. Liver histology demonstrated maintained lobular architecture, portal fibrosis of variable degree, sclerosis and obliteration of small-sized portal vein radicles, and subcapsular scarring with the collapse of the underlying parenchyma. Piecemeal or hepatocytic necrosis was absent in all histology specimens. Three patients showed nodular transformation along with abnormal liver functions, and may represent late manifestation of NCPF where features are similar to those seen in patients with incomplete septal cirrhosis. In the initial part of the study, surgery (side-to-side lieno-renal shunt) was the preferred modality of treatment, however, endoscopic sclerotherapy or variceal ligation has now become the preferred first line of management of variceal bleeding. CONCLUSIONS: The epidemiological and clinical features of NCPF have more similarity to IPH than has previously been documented. The development of spontaneous shunts tends to protect these patients from variceal bleeding.     

A 56 Year-Old Female with Congenital Hepatic Fibrosis Diagnosed by Laparoscopy

Abstract: We describe a 56-year-old woman with congenital hepatic fibrosis. Blood tests and liver scanning with Tc-99m-labelled galactosyl human serum albumin revealed mild liver dysfunction. Per-rectal portal scintigraphy with iodine-123 iodoamphetamine showed severe abnormalities in the portal circulation, and the portal pressure measured during percutaneous transhepatic portography was high (350 mmH₂O). Idiopathic portal hypertension was suspected. Laparoscopy disclosed diffuse, intense dendritic white markings around the liver. Congenital hepatic fibrosis was confirmed on histologic examination of a biopsy specimen obtained during laparoscopy. In summary, we report a rare and relatively elderly case of CHF, in which laparoscopy was useful in the diagnosis. (Dig Endosc 1999; 11: 174–178)
