Purpose: This study was undertaken to evaluate the gastroduodenal pathology and Helicobacter pylori infection in children with upper gastrointestinal symptoms. Methods: One hundred and seven pediatric patients with upper gastrointestinal symptoms were undergone endoscopy at the Gyeongsang National University Hospital from June 1990 to April 1991. Histopathologic examination was done by H & E staining of gastric antral biopsy specimen and gastritis was defined according to the Sydney System. Tissue H. pylori status was evaluated with the urease test using Christensen's urea broth and H & E or Warthin-Starry silver staining of gastric antral biopsy specimen. IgG Immunoblotting were also performed to detect specific anti-H. pylori antibody in these patients. Results: The reasons for endoscopy were recurrent abdominal pain, acute abdominal pain, sallow face, hunger pain, and frequent nausea. Variable degrees of gastric mucosal hyperemia were found in most of the patients. Gastric hemorrhagic spots, gastric ulcer, duodenal ulcer, duodenal erosion, and hemorrhagic duodenitis were rare endoscopic findings. Histologic chronic gastritis was found in 88% of 107 patients. Histologic chronic duodenitis was observed in all 99 patients whose tissue were available. Gastric tissue H. pylori was positive in 57% of 107 patients by one of the ureasetest, H & E staining and Warthin-Starry silver staining. However, gastric tissue H. pylori detection rate was lower in the younger age groups. Anti-H. pylori IgG antibodies were detectable in 96% of 107 patients. Conclusion: Chronic gastroduodenitis and anti-H. pylori IgG antibody were ubiquitous in children with upper gastrointestinal symptoms.

Purpose: This study was undertaken to evaluate the factors correlated with the clinical course and outcome in patients of Henoch-Sch${\ddot{o}}$nlein Purpura. Methods: The medical records of 104 children diagnosed with Henoch-Sch${\ddot{o}}$nlein Purpura (HSP) from January 1996 to April 2006 were reviewed retrospectively. The patients were divided into two groups: patients with Gastrointestinal (GI) symptoms and those without GI symptoms. When there were joint, scrotum, and renal symptoms except for skin lesion in whole HSP, those patients were excluded. The history of acute infection, duration of admission, treatment requirement, recurrence of HSP, CBC, stool occult blood test, abdominal ultrasonographic findings and GI endoscopic findings were reviewed. Results: Among 104 patients, patients with GI symptoms included 66 cases (63.5%), those without GI symptoms accounted for 38 cases (36.5%). GI symptoms included: abdominal pain in 57 cases (54.8%), vomiting 21 cases (20.2%), GI bleeding 5 cases (4.8%), nausea 3 cases (2.9%) and diarrhea 3 case (2.9%). Positive GI symptoms and GI mucosal lesions on GI endoscopy had a statistically significant correlation with increased admission duration, treatment requirement, recurrence of HSP, and positive stool occult blood. Six cases with small intestinal wall thickening were noted on abdominal ultrasonography. Six cases of hemorrhagic gastritis and hemorrhagic duodenitis, 3 cases of duodenal ulcer, 3 cases of hemorrhagic gastritis and duodenal ulcer, 2 cases of hemorrhagic duodenitis and colitis, and 1 case of colitis were noted on GI endoscopy. Conclusion: These results suggest that GI endoscopic examination may be helpful for the diagnosis and treatment of children with HSP.

Purpose: The aim of this study was to investigate the spectrum of gastrointestinal mucosal lesions in the children presenting with short-term abdominal pain. Methods: Thirty one children with short term abdominal pain for less than 1 month from January 1995 to May 2004 who were examined using gastrointestinal (GI) endoscopy were reviewed retrospectively. Children presenting with acute abdominal pain unrelated to proper GI were excluded from this study. Results: Male patients were 16 and female were 15. Three patients were 1~5 years old, 15 were 6~10 years old, and 13 were 11~15 years old. The duration of the abdominal pain was less than 7 days in 23 patients, 10 days in 1, 20 days in 2, and 30 days in 4. The major accompanying symptoms were vomiting (15), diarrhea (4), melena (1), hematemesis (1), and fever (2). Using endoscopy, 6 patients were found to have hemorrhagic gastritis, 5 nodular gastritis, 4 duodenal ulcer, 3 gastric ulcer, 3 reflux esophagitis, 2 nodular duodenitis, 2 superficial gastritis, 2 erosive hemorrhagic duodenitis, 2 ulcerative colitis, 1 duodenogastric reflux, and 1 esophageal polyp. Helicobacter pylori (H. pylori) infection was positive in 10 patients. The age and sex ratio, duration of abdominal pain, site of abdominal pain, and duration of abdominal pain between H. pylori- positive and negative children were different. However, only the site of abdominal pain (epigastric) showed statistical significance. All symptoms improved with medication for the GI mucosal lesions noted by the endoscopic findings. Conclusion: The author suggests that GI endoscopy be one of the important first steps in examinations to find out diverse GI mucosal lesions in the patients with short-term abdominal pain. Additionally, the examinations for H. pylori infection are important for these patients, also.

Purpose: There have been few reports about common gastrointestinal diseases in children visiting emergency room. The aim of this study was to present basic data and their meanings about emergency room utilization in children with nonsurgical gastrointestinal disorders. Methods: The authors prospectively studied 1,228 consecutive children with gastrointestinal diseases, amongst 6,179 nonsurgical pediatric patients who visited the emergency room of Seoul Red Cross Hospital from Jan. 1st 1998 to Dec. 31st 1999. Results: 1) First visit was 60.7% of total visits and 30.7% were between 1 and 3 years of age while 80.4% were below 6 years of age. Male patients were predominant by a ratio of 1.3:1. 2) The peak month of visits was December (12.1%), and the peak time of visits was between 8:00 pm and midnight (35.9%). Average length of stay at emergency room of the total patients were 0.86 hour. 3) Five major diseases were acute gastroenteritis (44.3%), fecal impaction &/or constipation (21.3%), acute gastritis (16.4%), intussusception (4.6%), and infantile colic (4.3%) in order. 4) 19.6% of the total patients were hospitalized. Conclusion: There were differences in various distributions regarding each nonsurgical gastrointestinal disease entity in children visiting emergency room even though distributions of the total patients in our study were not so different from those in previous reports by others.

Purpose: The five-year survival rate is over 95% for radically resected early gastric cancer. The development of diagnostic techniques enables early detection of gastric cancer, so the life expectancy of patients with early gastric cancer is prolonged. Therefore, a limited number of surgeries are performed these days for the purpose of increasing the quality of life. The purpose of this study is to assess the postoperative quality of life after a pylorus-preserving gastrectomy (PPG) compared with that after a subtotal gastrectomy with gastroduodenal anastomosis (B-I). Materials and Methods: One hundred seven (107) patients who underwent gastric surgery for early gastric cancer from January 1999 to December 2003 at the Department of Surgery of Chonnam National University Hospital were selected. We compared patients who underwent a PPG with those who underwent a B-I. The clinical results were compared by using the chi-square test and the Student's T-test. The data were considered to be significant when the P value was less than 0.05. Results: Twenty-nine patients (29) underwent a PPG, and the other seventy-eight (78) patients underwent a B-I. There was no significant difference between the two groups on sex, age, and postoperative abdominal symptoms. The patients who underwent a PPG showed shorter operation times and less reflux gastritis and esophagitis on endoscopic evaluation than the patients who underwent a B-I. Conclusion: The pylorus-preserving gastrectomy (PPG) is a more physiologic operation than the subtotal gastrectomy with gastroduodenal anastomosis (B-I) and improves the postoperative quality of life.

Purpose: An uncut Roux-en-Y gastrojejunostomy has been known to be effective in preventing bile reflux gastritis in the remnant stomach and the Roux stasis syndrome. Materials and Methods: To evaluate the usefulness of a totally laparoscopic uncut Roux-en-Y gastrojejunostomy (TLuRYGJ) after a distal gastrectomy, we reviewed the medical records of 19 consecutive patients that underwent a TLuRYGJ at our institution, and 11 consecutive patients who underwent a totally laparoscopic Billroth I gastrectomy (TLB-I) during the same period. Results: Postoperative gastrointestinal symptoms related to the postgastrectomy syndrome and the Visick classification at six months after surgery were not different in the two groups; however, there was no case of symptomatic bile reflux gastritis and only one case of delayed gastric empting, for which medication was required, in the TLuRYGJ group. The endoscopic findings of the remnant stomach for bile reflux gastritis at six months after surgery were better in the TLuRYGJ group than in the TLB-I group. Conclusion: A TLuRYGJ was found to be effective in preventing bile reflux gastritis and the Roux stasis syndrome.

This study was conducted to investigate the effects of hot spring water against the survival of food-borne and pathogenic microorganisms. Staphylococcus aureus, Bacillus cereus, and Escherichia coli, which are food-borne microorganisms, Candida albicans and Trichophyton mentagrophytes, which are skin disease pathogens, and Helicobacter pylori, gastritis inducing microorganism, were tested. The content of fluoride in tested hot spring water is 14.1 mg/L, which is higher than the standard of safe for drinking water 1.5 mg/L, but the results on 48 other items were up to the standard. Hot spring water didn't show the bactericidal effects against food-borne microorganisms, C. albicans, and H. pylori tested. However, the viable cell populations of B. cereus and T. mentagrophytes were decreased, which were depends on the temperature of hot spring water. From these results, we confirmed that hot spring water didn't show the bactericidal effects against food-borne microorganisms, skin disease pathogens, and gastritis inducing microorganism, but the growth of some microorganisms were inhibited by high temperature ($41^{\circ}C$).

Purpose : This study was performed to analyze the endoscopic findings in Henoch-Schonlein purpura patients, and to compare the differences in endoscopic findings according to age and gastrointestinal symptoms. Methods : We examined children with Henoch-Schonlein purpura aged 3 to 15 years between September 1996 and October 2002. The total number studied was 65, consisting of 41 boys and 24 girls. Endoscopy was performed and the results were analysed. Results : Among 65 cases, 12 cases of duodenitis, nine cases of gastritis and duodenitis, six cases of duodenal erosion, five cases of gastritis, five cases of duodenal ulcer, two cases of gastric ulcer and one case of colonic erosion were noted. Endoscopic abnormality was found in 38 of 53 who had gastrointestinal symptoms, and in two of 12 who didn't have gastrointestinal symptoms. Conclusion : Most of the gastrointestinal symptoms in Henoch-Schonlein purpura patients were relieved without complication. But in some cases severe symptoms such as hematemesis, melena, and abdominal pain localized to epigastric area were developed when diagnosis was delayed. Prompt endoscopy will be helpful for diagnosis and therapy of Henoch-Schonlein purpura with gastrointestinal involvement.

This study examined the protective effects of ginger and processed (Beopje) ginger extracts on gastritis induced by HCl-ethanol in SD-rats. Beopje (or Poje) is a branch of herbal medicines processed using a Korean traditional method to achieve specific pharmacological effects. Gastric lesions were induced in the rats by a treatment of 1 mL of HCl-ethanol (60% ethanol＋150 mM HCl). The rats were divided into seven groups: Normal (1 mL of saline without HCl-ethanol treated group), Control (HCl-ethanol treated group), GL (35 mg/kg of ginger treated group), BGL (35 mg/kg of Beopje ginger treated group), GH (350 mg/kg of ginger treated group), BGH (350 mg/kg of Beopje ginger treated group) and Cimetidine (80 mg/kg of cimetidine treated group). The gastric injury inhibition rate was 40.2% and 64.9% in GL and BGL and 68.4% and 99.6% in GH and BGH respectively, showing significantly lower rates than the control (p<0.05). The level of gastric juice secretion decreased significantly in all ginger administered groups. The pH of the gastric juices of BGH increased and the acidity of BGH and cimetidine decreased significantly (p<0.05) compared to the other groups. Beopje ginger had stronger inhibitory effects on gastritis than ginger without the Beopje process. The protective effect on gastritis by the ginger and Beopje ginger extracts increased in a dose-dependent manner (p<0.05). These results suggest that ginger has inhibitory effects on HCl-ethanol induced gastritis in rats that can be improved through the Beopje process.

Purpose: Helicobacter pylori infection is thought to be correlated with iron-deficiency anemia (IDA) at puberty. The H. pylori feoB gene, a high-affinity ferrous iron transporter, plays a central role in iron acquisition. This study aims to analyze the H. pylori feoB status according to the presence of antral gastritis with or without IDA. Methods: Fourteen H. pylori-positive patients aged from 10~18 years were categorized into subgroups based on the presence or absence of IDA. Eight patients had IDA, and the other six showed normal hematological findings. Genomic DNA was isolated from cultured H. pylori. Five sets of primers were used for PCR amplification of the feoB gene. The feoB region, 1.93 kb, was generated by linking of the PCR products and sequenced. The feoB gene sequences of H. pylori J99 and 26695 were used to compare with the clinical strains. Sequence comparisons of the feoB regions between the IDA (+) and (-) groups were performed. Results: Sequence analysis of the complete coding region of the feoB revealed 16 sites of polymorphism. Among these, 3 polymorphisms-Glu/Thr254Ala, Ile263Val, and Lys511Gln - were indigenous to Korean strains. Although statistically significant differences appear in 4 sites between IDA (+) and (-), the number of specimens are too low to assess the real differences. Conclusion: The 4 polymorphisms in the feoB gene seem to be related with IDA, but it is unclear yet because of small number of study strains. Further studies are required to prove the correlation of IDA and H. pylori infection.
