BACKGROUND/AIMS: The influence of Helicobacter pylori infection on gastric motility and sensation is unclear. Our hypothesis is that H. pylori infection increases gastric sensation and reduces gastric accommodation. METHODS: Seventeen healthy volunteers were recruited by public advertisement. Gastrointestinal symptoms were assessed by a questionnaire. All subjects underwent gastrofiberoscopy for assessment of organic diseases and for diagnosis of H. pylori infection. We evaluated for (1) proximal gastric compliance, (2) gastric sensation for three symptoms (nausea, abdominal fullness, and abdominal discomfort/pain) during balloon inflation and (3) fasting and postprandial proximal gastric tone using a barostat. RESULTS: The H. pylori negative (HP-) volunteers were eight (M:F=7:1, mean age 28+/-4 years) and the H. pylori positive (HP+) volunteers were nine (M:F=5:4, mean age 31+/-11 years). There was no difference in the fasting and the postprandial proximal gastric tone between the two groups. The minimal distending pressure was similar between the two groups [5.50+/-1.69(HP-) vs. 5.78+/-1.72 (HP+)]. No differences were detected on aggregate perception scores during the three levels of phasic distension. CONCLUSIONS: Our study suggests that H. pylori infection in asymptomatic subjects may not significantly alter gastric sensitivity or gastric accommodation.

Tuberculous involvement of the esophagus is very rare even in the presence of extensive pulmonary tuberculosis or in the endemic area. This is resulted from local extension to the esophagus from contiguous tuberculosis organs or miliary spread. Such secondary involvement is more common than primary tuberculosis, in which there is no evidence of tuberculosis elsewhere. The diagnosis of esophageal tuberculosis may be difficult. So the radiologic, endoscopic, histologic findings and clinical feature including the response to chemotherapy may be needed to avoid misdiagnosis. Most cases can be treated successfully with antituberculosis medication. A 67-year-old man was admitted to our hospital complaining of swallowing difficulty for 2 months. On the gastrofibroscopic examination, 22 cm sized protruding mass with central deep ulceration was discovered at the mid-esophagus. The biopsy showed the ulcer with chronic granulomatous inflammation and multinucleated giant cells consistent with tuberculosis. After antituberculosis medication, the lesion of esophageal tuberculosis was healed completely remaining minimal ulcer scar.

BACKGROUND: It has been known that the sero- logic markers of infectivity and viral replication in patients with hepatitis B virus(HBV) infection are hepatitis B e antigen(HBeAg), HRV DNA and HBV DNA polymerase. METHODS: In order to clarify the relationship between chronic liver diseases and HBV infection, and the mechanism of chronicity in HBV related liver diseases, the expression patterns of hepatic HBeAg by imrnunohistochemical stain and histologic activity index(HAI) were studied from 10% formalin fixed paraffin embedded tissues in 114 patients performed liver biopsy. RESULTS: The results were as follows: 1) Incidence of serum HReAg positivity in HBsAg positive patients was 74.6% and that of hepatic HBeAg expression was 77.6% among serum HBeAg positive cases. Hepatic HBeAg expression was 72.4% in serum HBeAg negative cases. 2) In serum HBeAg positive cases, almost all infected hepatocytes exhibited cytoplasmic HBeAg expression and half of patients showed nuclear HBeAg expression, but cytoplasmic HBeAg expression was solely predominant in serum HBeAg negative cases. Hepatic HBeAg expression showed a decreasing trend from AVH and CPH, through CAH, to cirrhosis with or without HCC, which was a consistent finding with serum HBeAg in decreasing manner. Hepatic HBeAg expreassion was highly sustained in about 60-90% of cases, regardless of duration of their illnesses. 3) HAI showed slighf3y higher tendency in patients with hepatic HBeAg negative expression than in positive cases. CONCLUSION: The above results suggest that HBeAg may play a role as a viral target antigen for immune-mediated liver injury and may be also related to the pathogenetic mechanism of chronicity in chronic hepatitis B.

BACKGROUND/AIMS: Chronic gastrointestinal (GI) symptoms are believed to be common in the general population, but there is a lack of data from Korea. The aim of this study was to estimate the prevalence of chronic gastrointestinal symptoms in a rural community in Korea by using the Bowel Symptom Questionnaire (BSQ), which was based on the multinational diagnostic Rome criteria for functional bowel disorders, as a measure of GI symptoms. METHODS: A cross-sectional survey, using a reliable and valid questionnaire based on the fulfillment of the Rome criteria, was performed in a densely populated district in a Korean rural community on the residents aged 18-69 yr (mean 48 +/- 14 yr). 95.5% responded (n=420). All respondents were interviewed at their home or offices by a team of interviewers. RESULTS: Two thirds of Korean rural residents experience gastrointestinal symptoms and one fifth of them visit a clinic or hospital at least once a year. Prevalences of weekly heartburn, gastroesophageal reflux disease, dyspepsia, irritable bowel syndrome (IBS), and chronic constipation were 5.2% (95% confidence interval [CI], 3.1-7.4), 2.6% (95% CI, 1.1-4.2), 15.5% (95% CI, 11.9-19.0), 8.6% (95% CI, 5.8-11.3), and 24.3% (95% CI, 20.1-28.5) respectively. The prevalence of dyspepsia was 25%, taking medication usage into consideration. Ulcer-like dyspepsia (11.2%) was the most common subtype and 40% of the subjects with dyspepsia were classified into more than one subtype of dyspesia. There was an overlap between subjects with IBS and dyspepsia with 6.1% of dypeptics having IBS and 11.1% of IBS patients having dypepsia. CONCLUSIONS: The prevalence of GERD was low in Korea compared with that of the Western contries. The prevalences of dyspepsia and IBS were similar to those of the Western countries. The most common gastrointestinal symptom in a rural community in Korea is dyspepsia.

BACKGROUND/AIMS: Endoscopic aspiration mucosectomy (EAM) can always lift up the lesion by suction regardless of its location and does not injure the mucosal surface. The clinical usefulness of this method was evaluated as follows. METHODS: Thirty two patients with gastric adenoma (35 lesions) and 6 patients with early gastric carcinoma were treated by EAM from March 1997 to February 1999. Their characteristics (diameter, macroscopic appearance, and histologic diagnosis) were verified at endoscopy with a biopsy specimen. The complete resection was defined as the presence of normal mucosa at the resected margin. RESULTS: The average size of the resected specimens was 17.8 mm in antrum and 16.5 mm in body. The ratio of complete resection by location was 67% in anterior wall, 88% in posterior wall, 86% in lesser curvature and 92% in greater curvature. The complete resection rate for smaller lesions (< or =15 mm) was highly distinguished from that of larger lesions (>15 mm). No serious complication was encountered. CONCLUSIONS: EAM is suitable for the treatment of gastric tumors. Lesions 15 mm or less in diameter can be resected easily by single procedure regardless of its location.

Polyethylene glycol solutions have been usually available for clinical use since 1980 and been considered a standard method of bowel preparations for colonoscopy. There have been many reports about minor complications such as nausea and bloating associated with their use, which are frequently occurred. After ingestion of polyethylene glycol, vomiting occurrs less frequently but it can make major complication such as Mallory-Weiss syndrome and aspiration pneumonia. We have reported here two cases of Mallory-Weiss syndrome, which were occurred after ingestion of polyethylene glycol solution for colonoscopy.

BACKGROUND/AIMS: We evaluated the effects of cisapride tartrate on gastrointestinal symptoms and gastric emptying times in diabetic patients with dysmotility like dyspeptic symptoms. METHODS: Cisapride was administered before each meal in 61 patients for 4 weeks. The intensity of gastrointestinal symptoms before and after cisapride administration was scored from 0 to 4, in the order of increasing severity of symptoms. In addition, a gastric emptying test was performed. RESULTS: A significant reduction in the total intensity score of symptoms was observed during the first two weeks, from 8.5+/-2.1 to 4.0+/-3.0 (p < 0.05), and a further reduction was noted during the next two weeks, to 2.8+/-2.8 (p < 0.05). Good to excellent improvement was obtained in 70.4% of the patients, but the improvement in symptoms was not related to age, duration of diabetes, glucose, Hb A1c, neuropathy, or retinopathy. Treatment with cisapride induced a significant regression of symptoms and a significant improvement of delayed gastric emptying from 104.0+/-31.7 minutes to 79.5+/-17.1 (p < 0.05). However, there was a lack of association between the changes in gastric emptying times and improvements in symptoms(r(2)=0.00186). Only 3 patients complained of loose stool, nausea, or dizziness. CONCLUSIONS: Cisapride was effective in improving dysmotility like dyspeptic symptoms in diabetic patients without serious side effects.

BACKGROUND/AIMS: There was some technical difficulty in applying the hemoclip on the posterior wall of the body, cardia of the stomach and posterior wall of duodenum because the angle of approach was tangential. Use of transparent cap on the tip of the endoscope could reduce some of these problems. The purpose of this study was to examine the efficacy of endoscopic hemoclipping using a transparent cap. METHODS: From August 1997 to July 2000, 74 patients with bleeding peptic ulcer and stigmata of recent hemorrhage were treated with endoscopic hemoclipping. There was technical difficulty in applying the hemoclip in 18 patients and the transparent cap was used. RESULTS: There was no statistically significant difference between the patients treated with cap and the patients treated without cap in initial hemostasis rate (91.1% vs 94.4%), rebleeding rate (11.8% vs 11.7%), and permanent hemostasis rate (92.9% vs 94.4%). CONCLUSIONS: Use of transparent cap on the tip of the endoscope was an efficient method when the angle of approach was tangential.
