Extrahepatic bile duct atresias must be classified into four histopathological groups according to the characteristic numerical, metrical, and morphological alterations of the interlobular bile ducts. A prospective study based on an observation period of 5 and more years included 43 patients with extrahepatic biliary atresia. It showed that prognosis is generally dependent on three factors: (1) the duration of cholestasis; (2) the structure of the bile ducts in the praehilaeren Versclussplatte; and (3) the histopathologically defined features of the interlobular bile ducts. The total diameter of all bile duct structures in the praehilaeren Verschlussplatte is unmistakably the most significant finding. A total diameter of more than 400 m indicates a favorable prognostic subtype, while a total diameter of less than 400 m is unfavorable. Even if the prognostically favorable type of finding is present, the ultimate prognosis is determined by the histopathological features of the interlobular bile ducts. Therefore, four characteristic groups must be taken into consideration when evaluating prognosis. 相似文献

Isolated injuries of the extrahepatic bile ducts due to blunt trauma are rare. The diagnosis in these cases is often delayed and there are no firm guidelines in regard to the treatment. We present a 3-year-old child with partial disruption of the confluence of the left and right hepatic ducts. A hepatic scintiscan was used to confirm the diagnosis and identify the site of the bile leak. The available literature has been reviewed briefly to highlight the clinical features that should arouse suspicion of such injuries and the various surgical options are discussed. 相似文献

We report the case of a 10 year-old girl who had Stevens-Johnson syndrome and cholestasis after ibuprofen therapy. Liver histology was compatible with vanishing bile duct syndrome. She received ursodeoxycholic acid, and liver tests normalized within 7 months. This report confirms that ibuprofen may induce acute vanishing bile duct syndrome. 相似文献

We report a newborn with bilious vomiting and the rare combination of pyloric atresia, annular pancreas and ectopic drainage of the common bile duct into the lesser curvature of the gastric antrum. Radiologic, sonographic and percutaneous transhepatic transcholecystic cholangiographic (PTTC) findings, with surgical correlation, are presented. 相似文献

Three infants with anterior abdominal wall defects (gastroschisis and exomphalos) who presented with obstructive jaundice secondary to biliary obstruction, are described. All three infants had abnormal biliary systems, with mechanical distortion of the biliary tree. Biliary obstruction secondary to structural biliary anomalies should be considered in patients with abdominal wall defects and cholestasis, as prolonged unrelieved biliary obstruction may lead to biliary cirrhosis and portal hypertension. 相似文献

A patient with spontaneous resolution of complete extrahepatic biliary obstruction shortly after the neonatal period is described. Liver biopsy prior to resolution revealed widened portal tracts and extensive fibrosis; these changes normalized following resolution. The aetiology was not established but possibilities included a choledochal cyst, localized inflammation; for example, pancreatitis, a calculus of the common bile duct or a congenital membrane. Management of this patient would have been advanced if there were a paediatric size side-viewing duodenoscope which would have diagnostic and therapeutic potentials. 相似文献

Combined chemotherapy and tracheobronchial stenting for life-threatening airway obstruction in a child with endobronchial non-Hodgkin lymphoma 总被引:1,自引:0,他引:1
Endobronchial involvement in non-Hodgkin lymphoma is rare even in the presence of advanced disease. A 15-year-old boy presented with progressively worsening dyspnea with occasional hemoptysis for 1 week prior to admission. Three days later, he was intubated due severe dyspnea with complete atelectasis of the right lung. Fiberoptic bronchoscopy disclosed an endobronchial mass almost occupying the right main bronchus. He underwent partial resection of the endobronchial tumor with rigid bronchoscopy. An airway stenting was used in this patient because he had severe tracheal obstruction from the tumor. The compromised airway was alleviated by combined chemotherapy and tracheobronchial stenting. 相似文献

We report an unusual case of duodenal duplication presenting in a newborn with duodenal and bile duct obstruction. The duplication and biliary tract were filled with keratinaceous casts. To our knowledge, such an association has not been previously reported; this case demonstrates the importance of confirming bile duct patency during operations to remove duodenal duplications. 相似文献

The maximum diameter of the common bile duct was measured on 85 normal intravenous cholangiograms carried out on children between the ages of 1–14 years. There was a close correlation between bile duct width and the patient's age, but a poor correlation with weight. The range of bile duct widths in each age group is tabulated as a guide to diagnosing biliary dilatation in childhood. 相似文献

Hydatid cysts developing primarily in the common bile duct are extremely rare. Occasionally, hydatid cysts rupture into the extrahepatic biliary ducts and cause obstruction [1–7]. Two children with intact hydatid cysts in the common bile duct and choledochal cysts were seen during a 2-year period in the Paediatric Surgery Division of the Children's Hospital, Banaras Hindu University, Varanasi. The details of their presentation and operative management are reported. 相似文献

This paper is a case report describing a boy with Down syndrome and a novel combination of multiple vascular anomalies: extrahepatic
portal hypertension, an arterio-venous malformation (AVM) at the ileo-caecal junction, and caval/iliac vein anomalies and
developing anal bleeding. We considered that the ileo-caecal AVM would be one of the causes of the repeated hematochezia.
The patient underwent ileo-caecal resection with the AVM, and anastomosis of the left external iliac vein and the jejunal
branch vein because of the stenosis of the superior mesenteric vein (Clatworthy mesocaval shunt). Intraoperative portal pressure
measurement at the site of the right colic vein showed a moderate pressure reduction (42.5–31.5 cm H2O). On the fourth month after operation, gastrointestinal fiberscopy showed no existence of esophageal varices. One year after
operation, the patient was doing well without bleeding. 相似文献

We describe a rare case of adenoma of the gallbladder associated with a gallstone in a 9-year-old girl who was successfully treated by cholecystectomy. The diagnosis, which was suspected on repeated ultrasonographic examinations of the gallbladder, was confirmed at surgery and histologic examination. To our knowledge, this is the third documented case of adenoma of the gallbladder and the first case associated with a gallstone in childhood.

Ectopic pancreas associated with a choledochal cyst and extrahepatic biliary atresia 总被引:4,自引:0,他引:4
Two children with incidentally-diagnosed ectopic pancreatic tissue in the jejunum at surgery for extrahepatic biliary atresia
(EHBA) and choledochal cyst (CC) are reported. No case has been reported in the literature describing the association of a
CC with ectopic pancreas, and only one case of EHBA associated with ectopic pancreas has been reported. We believe that incidentally-detected
ectopic pancreatic tissue should be excised, even though the patient is symptom-free, in order to prevent the risk of serious
complications due to either the mass effect or the potential for acute pancreatitis, cystic degeneration, or malignant transformation
at a later date.

BACKGROUND: Because of recent improvements in diagnostic procedures, many cases of congenital dilatation of the bile duct (CDBD) have been diagnosed in early life. To determine the mode of presentation and changes in diagnostic tools, medical records of 34 children (25 girls, nine boys) with CDBD who were treated between 1982 and 2000 were reviewed. RESULTS: The age at presentation ranged from 0 to 16 years (median 4.9 +/- 0.7 years), with two patients being diagnosed using prenatal ultrasonography. Of the 32 patients diagnosed post-natally, 21 (66%) complained of abdominal pain. There were also 21 (66%) cases of vomiting. Sixteen patients (50%) experienced both these symptoms. Ten (31%) cases presented with jaundice and three (9%) presented with a palpable mass. Ultrasonography was used as a diagnostic tool in 29 cases (85%). The finding of a dilated common bile duct on abdominal ultrasonography was helpful for early diagnosis. Spiral computed tomography was also a useful and accurate imaging method for diagnosis. Anomalous pancreaticobiliary junction (PBJ) was demonstrated in 44% of patients with CDBD. Magnetic resonance cholangiopancreatography, which can be performed non-invasively, is useful for the diagnosis and pre-operative assessment of CDBD in children. The average length of time from presentation to diagnosis could be shortened from 46 days (1982-1988) to 13 days (1995-2000). CONCLUSION: Recent improvements in diagnostic procedures make immediate, non-invasive diagnosis of CDBD and PBJ possible. 相似文献
