Endovascular stent-graft repair of aortocaval fistula complicated by the rupture of abdominal aortic aneurysm / 대한내과학회지

The incidence of infrarenal aneurym is about 6 percent after the age 60 years. A primary aortocaval fistula is present in less than 1% of all abdominal aortic aneurysms. Atherosclerotic abdominal aortic aneurysm account for about 90% of spontanous aortocaval fistula. The most common site of fistulation is the inferior vena cava. Until recently, surgical repair was the only method of treatment and was associated high incidence of morbidity and motality. With rapid development of aortic stent-graft technique, endovascular stent-graft repair may offer an alterative to the management of this often fatal condition. We report a case of 72-years old male with aortocaval fistula in the abdominal aorta, which was treated with endovascular stent-graft implantation. About 30 days before procedure, the patient diagnosed inferior acute myocardial infarction with triple vessel disease and also suffered from chronic obstructive pulmonary disease. After the stent-graft inserting, no further communication from aorta to inferior vena cava and improving symptoms and sign of congestive heart failure. He was discharged without complication, about 2 months after admission.

Infestation state of clonorchis sinensis in patients with pancreatobiliary diseases in ulsan: based on bile examination / 대한내과학회지

BACKGROUND: Bile examination is believed to be the most precise method for detecting Clonorchis sinensis (CS) eggs. We carried out bile examination to evaluate infestation state of CS in patients with pancreatobiliary diseases in Ulsan, known as an endemic area of CS infestation. METHODS: We examined CS eggs in bile in three hundreds and nine patients with pancreatobiliary diseases. The bile was obtained from endoscopic nasobiliary or percutaneous transhepatic biliary drainage tubes. RESULTS: The overall egg positive rate was 27.5% (35.3% in male, 17.6% in female). The egg positive rate was not significantly different according to the age group: 20.0% in thirties, 26.7% in forties, 24.2% in fifties, 29.9% in sixties, 36.2% in seventies and 16.7% in eighties or more. The egg positive rate according to the disease, except CS cholangitis, was not also statistically different: 32.6% in bile duct cancer, 38.5% in gallbladder cancer, 11.1% in ampulla of Vater cancer, 24.0% in pancreatic cancer, 26.4% in gallstone diseases and 12.5% in the reminder. The location of gallstone and whether CS related diseases or CS unrelated diseases did not affect the egg positive rates. The egg positive rate in patients with normal radiological findings including cholangiography was 17.0%. CONCLUSION: This result shows that regardless of age, sex, and sorts of diseases, the infestation rate of CS was very high. On the basis of our results, it is therefore presumes that clonorchiasis is still endemic disease in Korea.

Diagnostic role of biliary carcinoembryonic antigen in patients with pancreatobiliary diseases / 대한내과학회지

BACKGROUN: Recently there has been notion that fluids bathing tumors might contain higher levels of carcinoembryonic antigen (CEA) than those found in the blood. Thus, we evaluated the diagnostic role of biliary CEA in patients with pancreatobiliary diseases. METHODS: One hundred and twenty one patients were prospectively studied. The patients were grouped as control (n=21), benign diseases (n=57), and malignant diseases (n=43). All patients underwent endoscopic or percutaneous biliary drainage. Bile was obtained and analyzed for CEA concentration on the next day of biliary drainage procedure. RESULTS: The mean biliary CEA were significantly different among the groups: control, 3.6 +/- 6.5 ng/mL; benign diseases, 35.4 +/- 59.2 ng/mL; malignant diseases, 77.9 +/- 126.6 ng/mL. But, there was considerable overlap among the groups. With a cut-off level of 22 ng/mL, the sensitivity and specificity were 58.1% and 60.5%, respectively. Among the variables, biliary CEA, total bilirubin, and gamma-GT were directly correlated with presence of malignancy. However, multivariate analysis revealed that biliary CEA was not enough to differentiate malignant diseases from benign diseases. CONCLUSION: Although biliary CEA levels might be predictive of malignancy, it is very difficult to differentiate with fair certainty between the two diseases because of the considerable overlap. Thus, biliary CEA appears to have a limitation for routine clinical application in distinguishing between benign and malignant diseases.

Diagnostic Usefulness of Intradermal Test for Clonorchiasis in Patients with Pancreatobiliary Diseases / 대한소화기학회지

BACKGROUND/AIMS: The diagnosis of clonorchiasis is based on demonstrating eggs in stool or bile. It is believed that bile examination is the most precise method for detecting eggs. We evaluated diagnostic usefulness of intradermal test (IDT) by comparing it with the result of bile examination. METHODS: For 88 patients with pancreatobiliary diseases, we examined Clonorchis sinensis eggs in bile and performed IDT for clonorchiasis. The bile was obtained from endoscopic nasobiliary or percutaneous transhepatic biliary drainage tubes. RESULTS: We calculated ROC curve to decide the cut-off value of IDT in determining diagnostic accuracy on the basis of bile examination. We chose a value of 40 mm2, which significantly improved the sensitivity, without reducing the specificity. With a cut-off value of 40 mm2, the sensitivity, specificity, positive and negative predictive values of IDT were 81.5%, 67.2%, 52.4%, and 89.1%, respectively. The value of IDT was not affected by age and showed no difference between benign and malignant diseases. However, in egg-positive patients, the mean value was lower in malignant diseases than in benign diseases. CONCLUSIONS: In patients with pancreatobiliary diseases, IDT with a cut-off value of 40 mm2 seems to be a valuable supplementary diagnostic test for clonorchiasis in view of its high sensitivity.
