To investigate the diagnostic accuracy of ERCP in pancreatobiliary disease, the authors analysed the 1,244 cases of ERCP. The success rate of ERCP was 91.5%. The diagnostic accuracy of ERCP was 93.6% and complications occurred in 2.1%. Complications included pancreatitis,cholangitis and drug reactions. Among the biliary tract disease diagnosed, by ERCP, biliary tract stone was the most common finding. Compared with operative diagnosis of biliary tract stones,the sensitivity of ERCP diagnosis was 92.7% while that of sonographic diagnosis was 81.4%. The specificity of ERCP diagnosis was 94.4% while that of sonagraphic diagnosis was 80.9%. ln the diagnosis of common bile duct stones, ERCP was more accurrate than sonographic diagnosis. The results show that ERCP was a safe and effective diagnostic tool in the assessment of pancreatobiliary tract disease.

PURPOSE:Insulin induced hypoglycemia and L-dopa are potent for growth hormone(GH) secretion in children. We evaluated the effects of GH secretion with insulin and L-dopa in 22 children with height percentile below 3 and 11 children with height percentile between 10 to 25. METHODS:Thirty four children were performed GH secretion study after classified by height percentile and bone age according to their age and sex. Twenty two children are height percentile below 3 and bone age is delayed more than one years compare to chronologic age(group A). As a control group, twelve children took part in this study and their height percentile were between 10 to 25 but, bone age was not concerned(group B). Serum GH concentration and blood glucose level was detected on 0, 30, 60, and 90 minutes after insulin 0.1U/kg was injected intravenously. And then serum GH concentration was measured on 0, 30, 60, and 90 minutes after L-dopa 10mg/kg was administered orally. Serum GH was measured by radioimmunoassay. RESULTS:GH level in group A was below 7ng/mL in 13 children(59%) after insulin and L-dopa administration respectively but in 11 children(50%) GH level were all below 7ng/mL after insulin and L-dopa adminstration. GH deficiency(7ng/mL) was detected only one children in group B. In Group A and B, peak GH concentration was noted on 30 minutes after insulin administration, but on 60 minutes after L-dopa, peak GH concentration appeared in group B. GH concentration in zero time to 90 minutes after L-dopa was steady increased in group A. CONCLUSION: Anthropometric data such as height percentile and bone age are good for prediction of GH deficiency and if we use these data and GH secretory effects of insulin induced hypoglycemia and L-dopa, we can predict GH deficiency more accurately.

The usefulness of microscopic examination of pure bile directly collected from the biliary tract during endoscopic retrograde cholangiography and without hormonal stimulation was evaluated in 86 patients. Cholesterol monohydrate crystal and/or calcium bilirubinate granule were observed in the bile of 64% of GB stones, 88% of CBD stones and l00% of IHD stones. But only 4% of non stone control group were positive crystals examinations. According to this results, microscopic examinations:of bile samples collected during endoscopic retrograde cholangiography exhibited a sensitivity and a specificity for cholelithiasis recognition of 82.3% and 95.8%, respectively, with a positive and negative predictive value of 98.1% and 67.6%, respectively. We conclude that microscopic bile examinations of bile samples collected during ERC is useful to investigate in patients with suspected cholelithiasis.

Despite significant advances in the diagnosis and treatment of various malignancies, the management of esophageal cancer remains one of the least responsive malignancies, Unfortunately complete excision of the tumor is impossible, because expandable anatomic structures are involved early when the diagnosis is made.

Sweets syndrome has 4 cardinal features, that is, fever, neutrophil polymorphonuclear leukocytosis of the blood, raised painful plaques on the limbs, face and neck, histologically a dense dermal infiltration with mature neutrophil polymorphs. Hematologic malignancies are associated with 10-15% of cases, but gastric adenocarcinoma associated case is very rare. A 57-year-old male patient admitted to Korea University affiliated hospital because of fever and painful erythematous plaques of both limbs. No response to antibiotics and antihistamines for 1 week, so we referred to dermatologic department for skin biopsy. After then under the impression of Sweet's syndrome, oral prednisolone 60 mg/day prescribed and skin lesions were progressively regressed. For the purpose of screening of associated disease, we did abdominal CT scan and panendoscopy with biopsy which revealed adenocarcinoma of stomach. We couldn't find out any other etiologic agents.
