Hamartomatous polyps in the stomach have been described as gastric lesions of familial polyposis coli or not associated with polyposis coli. However, submucosal tumor-like lesion of the gastric hamartoma is very rare. We have experienced an unusual hamartoma in the stomach in a 69-year-old man. He was hospitalized with epigastric discomfort. Endoscopy revealed a submucosal mass at the greater curvature of the high body of the stomach. The resected mass measured 3 X 2 X 1.5 cm and was characterized by cystic dilation of glandular structures. The glandular structures consisted of various types of lining cells, including surface foveolar cell types, pyloric cell types and parietal-like cells, and irregularly arranged smooth muscle bundles and collagen fibers were noted. We report this unusual gastric hamartoma presenting as a submucosal tumor with a review of literatures.

Primary sclerosing cholangitis is a cholestatic liver disease characterized by fibroobliterative inflammation of the entire biliary tree. It is a slowly progressive disease with an undulating course, resulting in biliary cirrhosis. The gold standard for establishing the diagnosis is cholangiographic demonstration of typical diffuse biliary stricturing and beading. We exprienced a case of primary sclerosing cholangitis by Endoscopic retrograde cholangiopancreatography (ERCP) demonstration. ERCP findings revealed multiple luminal narrowing, stricture and beaded dilatation of the intrahepatic duct. We report a case of primary sclerosing cholangitis localizing at intrahepatic bile duct, which is confused with cholangiocarcinoma.

The occurrence of papillary restenosis following endoscopic sphincterotomy is uncommon and usually reported as a late complication. Its frequency varies from 0.8% to 3% and at present, only a few reports describe the late complication rate for a mean follow-up exceeding 10 years. The diameter of the sphincterotomy opening diminishes by about 30% in the first year without further narrowing, suggesting that restenosis occurs mainly during the first post-sphincterotomy year. Papillary restenosis may be promoted by insufficient cutting and may depend on the indication for EST such as common bile duct stones, papillary stenosis, duodenal diverticular, sphincter of Oddi dysfunction. A bleeding sphincterotomy requiring a sclerosing injection is considered a potential risk factor for papillary stenosis. However, stenosis may develop in the absence of specific predisposing factors. A case of papillary restenosis following endoscopic sphincterotomy for gollstone pancreatitis in a 33-year-old female patient is herein reported.

BACKGROUND/AIMS: The duodenal intubation test (duodenal secretin test; DST) is now considered the 'gold standard' test of exocrine pancreatic function in detecting exocrine pancreatic dysfunction in patients with chronic pancreatitis. However, the DST has not been widely used, because it is time-consuming, invasive, and labor-intensive. On the other hand, intraductal secretin test (IDST) with endoscopic retrograde cannulation of the main pancreatic duct has been showed similar diagnostic efficiency compared with DST. We assessed the clinical usefulness of IDST and investigated parameters for assessing impaired pancreatic function of IDST. METHODS: Pure pancreatic juices were collected from 12 patients with chronic pancreatitis by endoscopic cannulation after a bolus intravenous injection of secretin 100 U, for 15min in three 5-min intervals. Five parameters of IDST were measured, and the sensitivity, specificity, and accuracy of IDST evaluated compared with ERP. RESULTS: When we regarded mean-1.5 SD as the lower limits of IDST, the diagnostic sensitivity, specificity, and accuracy of five parameters to detect chronic pancreatitis were 91.7-100%, 75-87.5%, and 85-90%, respectively. Among five parameters, pancreatic juice secretory volume, bicarbonate concentration, and amylase output showed the highest diagnostic accuracy, followed by lipase output and bicarbonate output. A 10-min collection showed as much information as a 15-min collection. CONCLUSIONS: 10-min intraductal secretin test is useful as the conventional exocrine pancreatic function test in detecting exocrine pancreatic dysfunction in patients with chronic pancreatitis and the most discriminatory parameters are pancreatic juice secretory volume, bicarbonate concentration, and amylase output.

Pancreatic pseudocysts are a well-recognized complication of pancreatitis. Most occur in or adjacent to the pancreas. Occasionally, duodenal involvement may occur due to the nonperitonealized posterior surface of the duodenum is in direct contact with the head of the pancreas. But there is little awareness of the intramural and major extrinsic involvement of the duodenum with also occurs. A case was recently experienced involving an intramural pancreatic pseudocyst of the duodenum.

Candidiasis of the gastrointestinal tract typically occurs in a setting of decreased re- sistance to opportunistic infection, but also occurs in apparently normal individuals. Mucosal lesions in the gastrointestinal tract predominantly involve the esophagus, and gastroduodenal and enteric candidial lesions, which are less frequent, have only infrequently been detected antemortem. A case was experienced involving esophageal and gastroduodenal candidiasis in the patient of hepatocellular carcinoma and spinal metastasis treated with emergent radiotherapy and corticosteroid. He complained of anorexia and dyaphagia in the 4th day of radiotherapy. Endoscopy revealed multiple, large raised, white plaques and patches covering the mid- and distal esophageal mucosa, and several superficial aphthous ulcerations covered with white plaques in the entire stomach, and two deep excavating ulcers at the angle and antrum. The duodenal mucosa was covered with multiple small, white plaques, and a huge penetraing ulcer was seen in the duodenal bulb. Endoscopic biopsy showed budding yeast and pseudohyphae infiltrating through the ulcerated mucosa. Cultures of the same material canfirmed the organism to be Candida albicans. The patient was treated with fluconazole for 2 weeks. The case of esophgeal and gastroduodenal candidiasis is reported with reviiew of relevant literature.

BACKGROUND/AIMS: The success of Helicobacter pylori eradication is limited by antibiotic resistances, and the primary resistance to metranidazole seems to be high. In this study, the frequency af metronidazole resistance and the eradication rate in metronidazole-resistant H. pylori strain was evaluated. METHODS: Sixty-eight patients were tested for metronidazole resistance using microdilution broth, the E test and disk diffusion method. Twenty-two patients were treated for 14 days with amoxicilline 2000 mg, metronidazole 750 mg, and tripotassium dicitrate bismuth 1200 mg. RESULTS: Metronida-zole resistance was 46% (31/68). The eradication rates for H. pylori was 91.7% in patients with metronidazole-sensistive strains and 70% in patients with metronidazole-resistant strains. CONCLUSIONS: Metronidazole resistance was high (46%) in Korea, however, triple therapy was an efficient method of eradicating H. pylori in both metronidazole sensitive and resistant strains.

Pancreatic pseudocysts were complicated in 10-27% of acute pancreatitis and 11-41% of chronic pancreatitis. Asymptomatic pseudocysts require no treatment, but symptomatic pseudocysts should be decompressed. Surgical management had been the traditional approach to treating pancreatic pseudocysts. Endoscopic transpapillary or transduodenal cystoenterostomy were recently suggested as an alternative to surgery in order to avoid surgical complications. The success rates of endoscopic treatment was 65-94%, procedure related morbidity was 6-21% and mortality was 0-5%. We reported two cases of patients with pancreatic pseudocysts which were treated with endoscopic cystogastrostomy and proceeded to drain through stent and ENPD catheter.

Tetrodotoxin is a neurotoxin produced by about 90 species of puffer fish and causes paralysis of central nervous system and peripheral nerves by blocking the movement of all monovalent cations. Ingestion of tetrodotoxin produces clinical manifestations such as paresthesias(within 10-45 min), vomiting, lightheadedness, salivation, muscle twitching, dysphagia, difficulty in speaking, convulsion and death that expressed by cardiopulmonary arrest with loss of brain stem reflex sometimes. Tetrodotoxin prevents or delays ischemia induced neuronal death by way of following 3 mechanisms. Firstly, it reduces the energy demand of the brain tissues. Secondly, it delays or even prevents anoxic depolarization. Finally, it diminishes ischemia induced cell swelling and cerebral edema. We report a case of puffer fish poisoning which presented with cardiopulmonary arrest and loss of brain stem reflex, but completely recovered by aggressive cardiopulmonary resuscitation.

The web of the common bile duct is an extremely rare anomaly and the cause of the obstructive jaundice. We experienced a case of the congenital web of common bile duct in a 42 years old male who complained of jaundice for 10 days prior to admission without choledocholithiasis and cholangitis. An endoscopic retrograde cholangiopancreatography revealed a common bile duct web (transverse, diaphragmatic type) and the diagnosis was confirmed by an endoscopic forcep biopsy. We reported a case of the congenita1 web of the common bile duct which was treated with a stent insertion and balloon dilatation.
