1/8. Obstruction of common bile duct caused by liver fluke--fasciola hepatica.Three cases of obstruction of the common bile duct by fasciola hepatica with two of the patients presenting jaundice are reported. The authors have reviewed several publications concerning common bile duct obstruction by liver fluke, a quite rare complication of fascioliasis. Only nineteen cases of common bile duct obstruction caused by fasciola hepatica have been reported in a review of medical publications during last ten years. Clinical presentation, diagnostic methods and considerations, types of surgery are fairly uniform in all of the reported cases. Almost all of patients reviewed, had the history, symptoms and signs characteristic for cholelithiasis including recurrent colic pain in right hypochondriac area, fever or subfebrile temperature, fluctuating or stabile jaundice, and palpable painful gallbladder. The laboratory findings in all cases reviewed had shown leucocytosis, eosinophilia, high or slight elevated serum bilirubin. Echographically commonly revealed dilated intra- and extrahepatic bile ducts containing one or more hyperechogenic elements with or without casting an acoustic shadow. All patients underwent open surgery, comprised with choledochotomy and if possible extraction of the fluke. Only two postoperative cases were of necessity followed by ERCP. In all of our cases the primary pre-operative diagnosis was choledocholithiasis, with diagnose of fascioliasis established at the operation. According to the literature this uncertainty in diagnosis is common because of difficulties in differentiation of fascioliasis versus choledocholithiasis. Considerations for making the differential diagnosis--a history of origin or visiting in endemic area of infection, history of eating of aquatic vegetables, laboratory findings including eosinophilia, fasciola eggs in stool, sonography and radiological imaging results and enzyme-linked immunosorbent essay (ELISA) which has been shown to be rapid, sensitive and quantitative. In all three cases we have observed intraoperative significant signs for liver fascioliasis to include surface scarring of the left lobe on the liver--tracks caused by subcapsular migration and location of the hepatic lesions (these findings were also seen by two authors in literature) with resemblance to Japanese letters. The most effective drug for treatment of fascioliasis according to our experience and literature reviewed is bithionol.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
2/8. Xanthogranulomatous choledochitis: a previously undescribed mass lesion of the hepatobiliary and ampullary region.Solid liver and pancreatic masses are commonly neoplastic in nature; however, inflammatory lesions mimicking carcinoma are at times encountered in these sites. We report two cases of previously undescribed inflammatory mass lesions of the liver and pancreas that originated in the biliary tract. Detailed clinical and histologic evaluations were performed in two patients who underwent right partial hepatic lobectomy and Whipple's resection for presumed hepatic and pancreatic neoplasms. In case 1, with a remote history of cholecystectomy and recent extraction of a stone from the common bile duct, a liver mass in segment 6 was discovered incidentally. In case 2, a periampullary pancreatic mass was diagnosed radiographically following papillotomy and stent insertion for stricture and biliary calculous disease. The histologic findings in both cases were similar, localized around a part of the biliary tract, and consisted of inspissated bile, acute and chronic inflammation, abundant lipid-laden macrophages, fibrosis, and giant cell reaction. No neoplasm was identified. On the basis of the close resemblance of these features to those seen in xanthogranulomatous cholecystitis, the lesions seen here were termed xanthogranulomatous choledochitis. In conclusion, xanthogranulomatous choledochitis is a benign inflammatory process involving the biliary tract that can form a mass lesion within the liver or pancreas and thus mimic a neoplasm. Extensive sampling of the lesion is required to rule out an underlying neoplastic process. In our patients a propensity to form lithogenic bile and a prior history of biliary tract operative procedure were present.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
3/8. An unusual cause of recurrent biliary colics.Hepato-biliary ascariasis is a rare condition in non-endemic areas; however, it should always be taken into account in patients with recurrent biliary colics and/or cholangitis, since these are among the most frequent modes of clinical presentation. We report a case of a young woman suffering from recurrent biliary colics in whom a diagnosis of biliary ascariasis was made. Endoscopic retrograde cholangiopancreatography with sphincterotomy and endoscopic extraction of the worm, using a Dormia basket, proved to be a safe and effective procedure for removing the living Ascaris from the biliary tree and relieving symptoms. In the era of worldwide travels, physicians in Western countries should be more aware of this infection especially in patients with biliary symptoms who have travelled to endemic areas or immigrant from endemic countries.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
4/8. Ascaris in the common bile duct: diagnosis by ultrasound and endoscopic retrograde cholangiopancreatography (ERCP) and extraction by balloon catheter.This is a case report of ascaris worm in the common bile duct in a 61 year old lady. Ultrasound diagnosis was initially made based on the presence of linear hyperreflective foci within the common bile duct. ERCP confirmed a single worm within the duct. Balloon extraction was then successfully carried out following papillotomy. This case illustrates the value of ultrasound in the definitive diagnosis of biliary ascariasis and the therapeutic role of ERCP.- - - - - - - - - - ranking = 5keywords = extraction (Clic here for more details about this article) |
5/8. Biliary imaging suggesting common duct obstruction in acute viral hepatitis. Case report.A patient with right upper quadrant pain showed normal tracer extraction and a prolonged hepatocellular phase during biliary imaging, findings that are most consistent with complete common duct obstruction. He had no other evidence of biliary tract obstruction and was diagnosed subsequently as having viral hepatitis. hepatitis must be considered when biliary imaging suggests complete common bile duct obstruction.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
6/8. Biliary ascariasis combined with a villous tumor of the papilla. Diagnostic and therapeutic value of endoscopy.A 64-year-old man admitted for cholangitis presented with an ascaris lumbricoides in the biliary duct and a villous tumor of the ampulla of vater. ERCP revealed the parasite as a "rail-like" linear defect in the main bile duct, and permitted its extraction. The ampullary tumor was repeatedly ablated with a snare and finally surgically removed because of suspicion of malignancy. This is the first report on such an association.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
7/8. Ultrasound in the diagnosis of roundworms in gallbladder and common bile duct. Report of four cases.Four patients who complained of symptoms and signs compatible with biliary tract disease and in whom the diagnosis of gallbladder (three cases) and common bile duct ascariasis (one case) was made sonographically are reported. In two patients with gallbladder ascariasis, cholecystectomy corroborated the presence of the round-worms, and was curative. The third patient was a pregnant woman (32nd gestational week) who took piperazine citrate, and a second sonogram performed 29 days later was completely normal. The fourth patient with common bile duct ascariasis underwent choledochotomy with extraction of one ascaris lumbricoides from the common duct, and a T tube was left in place for 15 days. All patients received antiparasitics and had a favorable outcome. ultrasonography is an important noninvasive diagnostic procedure in the work-up of these patients, who usually describe a clinical picture suggesting gallstone disease: this is especially true in the presence of pregnancy.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
8/8. Endoscopic treatment of biliary ascariasis. Report of a case.ascaris lumbricoides is the most common intestinal parasite to infect humans. The incidence of ascariasis is increasing in our regions, due to world travel and population migration. In one third of cases, the worm can enter the bile duct and cause cholangitis or biliary colics. diagnosis and treatment of ascariasis are discussed. Endoscopic retrograde cholangio-pancreaticography (ERCP) with endoscopic extraction of the worm, using a Dormia basket, is a safe and effective procedure for the diagnosis and treatment of biliary ascariasis. This technique serves as an effective alternative for surgery.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
