Difference in the distribution pattern of Helicobacter pylori and grade of gastritis in the antrum and in the body between duodenal ulcer and benign gastric ulcer patients

OBJECTIVES: To investigate the relationship between the Helicobacter pylori (H. pylori) colonization and the grade of gastritis in the antrum and in the body of patients with duodenal ulcer (DU) or benign gastric ulcer (BGU). METHODS: This study was performed in H. pylori-positive 220 DU patients and 180 BGU patients. H. pylori density was evaluated by modified Giemsa staining and CLO test, and gastritis grade was graded by H+ACY-E staining in the antrum and in the body. RESULTS: H. pylori grade by Giemsa staining was 1.24 in the antrum and 0.82 in the body for DU group (p +ADw- 0.01), and those of BGU group were slightly reversed, 0.83 and 0.87, respectively, but without statistical significance. Similarly H. pylori grade by CLO test was 3.1 in the antrum and 2.8 in the body for DU group (p +ADw- 0.01), and those of BGU group 2.3 and 2.6 (p +ADw- 0.05), respectively. In contrast, gastritis grade was 1.7 in the antrum and 1.2 in the body for DU group (p +ADw- 0.01), and those of BGU group 1.6 and 1.3 (p +ADw- 0.01), respectively, similar to those of DU. However, there was a correlation between H. pylori grade and gastritis grade in the antrum and in the body, not only in DU but also in BGU group (p +ADw- 0.01). CONCLUSION: In spite of different distribution patterns of H. pylori between DU group and BGU group, gastritis grade of the antrum was significantly higher than that of the body in both DU and BGU. However, gastritis is correlated with H. pylori density not only in DU but also in BGU patients. It looks like the inflammatory reaction to H. pylori is stronger in the antrum than in the body.

Effect of eradication of Helicobacter pylori on the benign gastric ulcer recurrence - a 24 month follow-up study

OBJECTIVES: To evaluate the effect of eradication of Helicobacter pylori (H. pylori) on the recurrence of benign gastric ulcer (BGU) in the patients with BGU. METHODS: This study was performed for 40 H. pylori-positive BGU patients cured of BGU and H. pylori eradicated, and for 25 H. pylori-positive patients (non-eradicated group) who were not treated with H. pylori eradication regimen or H. pylori was not eradicated. Four different methods--CLOtest, microscopy of Gram stained mucosal smear, culture and histology of modified Giemsa staining--were taken for identifying colonization of H. pylori before treatment, and 4 weeks after completion of triple therapy. For the control group in which triple therapy was not tried, follow-up gastroscopy was done to confirm the healing of the ulcer. To detect BGU recurrence, the gastroscopy was performed at 6, 12, 18, and 24 months after therapy. RESULTS: In the non-eradicated group, the BGU recurrence rate was 16% within 6 months, 40% within 1 year, 56% within 18 months and 60% within 2 years. The respective recurrence rates in the 40 patients in whom the bacteria had been eradicated were 0%, 7.5%, 10% and 10% (4 patients), respectively. Among the four BGU-recurred patients in whom H. pylori had been eradicated, one patient was found to have BGU recurring with H. pylori positive again in one year, and another two patients had NSAIDs ingestion history. CONCLUSION: The eradication of H. pylori in patients with BGU reduces the recurrence of BGU. In addition, the major causes of BGU recurrence look like NSAIDs ingestion and reinfection of H. pylori.

The Role of Helicobacter pylori and NSAID in Patients with Benign Gastric Ulcer / 대한내과학회지

OBJECTIVES: H. pylori infection and NSAID are very important risk factors for peptic ulcer. This study was conducted to investigate the H. pylori positivity rate and the rate of NSAID ingestion in the patients with benign gastric ulcer(BGU), to investigate which test and which site are the most adequate to reduce the false positivity rate of H. pylori, and finally to investigate the role of H. pylori and NSAID in BGU bleeding. METHODS: This study was conducted for the 180 patients with BGU, and H. pylori was diagnosed by any of CLO test, Gram stain of touch print and H&E stain in the antrum and body. In addition, age, sex, ingestion history of NSAID within 4 weeks before gastroscopy, past BGU history, smoking, alcohol and BGU bleeding were investigated. RESULTS: 1) The H. pylori infection rate of patients with BGU in Korea was 82.8%, and the rate of NSAID history was 26.1%. The patients with BGU who have only NSAID history were 8.3%, and the 91.1% of the patients had either H. pylori infection or NSAID history. 2) The most sensitive test for H. pylori infection among CLO test, Gram stain of touch print and H&E stain in the antrum or body was CLO test in the body. 3) Depending on H. pylori positivity, the rate of NSAID history in the H. pylori negative group was 48.4%, which was higher than that of H. pylori positive, 21.5%(p=0.002). In addition, the rate of past BGU history in the H. pylori positive group was 47.0%, which was higher than that of H. pylori negative, 12.9%(p<0.001). 4) Depending on the history of NSAID, the H. pylori positivity rate in NSAID positive group was 68.1%, which was lower than that of NSAID negative, 88.0%(p=0.002). The female percentage of NSAID positive was 40.4%, which was higher than that of NSAID negative, 16.5% (p<0.001). The rate of BGU bleeding in the NSAID positive was 27.7%, which was higher than that of NSAID negative, 14.3%(p=0.039). 5) The rate of NSAID history of bleeding group was 40.6%, which was higher than that of non-bleeding group, 23.0%(p=0.039). However, there was no signifi cance in the correlation of H. pylori positivity rate to the bleeding. 6) The H. pylori positivity and NSAID history showed no correlation with bleeding in the group below age sixty. While in the age over or equal to sixty the H. pylori positivity had no correlation with bleeding, but the rate of NSAID history was 72.7% for the patients with bleeding, which is in contrast with the 25.5% for the patients without bleeding(p=0.003). CONCLUSION: From these results, the H. pylori infection rate of the patients with BGU in Korea was 82.8%, and the best method for H. pylori detection was CLO test in the body. H. pylori infection had no corre lation with the bleeding, but NSAID ingestion increased bleeding tendency, particularly in the group of the age over or equal to sixty.

A Caae of Gastrocolie Fistula Secondary to Benign Gastric Ulcer / 대한소화기내시경학회지

Gastrocolic fistula is a rare lesion which is caused most commonly by carcinoma of colon or stomach. The less common causes of gastrocolic fistula are follows: trauma, faulty gastrocolic anastomosis during gastrectomy, benign gastric ulcer, syphilis, carcinoid tumor, tuberculosis, intraperitoneal abscess, lymphoma, perforated diverticulum of colon, and ulcerative colitis. The locations of fistulae are mostly between greater curvature of stomach and distal half of the transverse colon. In the case of penetrating benign gastric ulcer and gastrcolic fistula, it is usually associated either with asipirin or with prolonged steroid administration. A 36-year-old male who had an unusual gastrocolic fistula secondary to non-surgically treated benign gastric ulcer is presented. The exitence of a gastrocolic fistula was dernonstrated by radiological examination of the colon and the stomach. In this patient, the colonoscope passde through the fistula and the stomach could be examined. Careful preparation was carried out preoperatively with intravenous fluids and blood transfusions. Resection of the distal stomch, fistulous tract, and segment of the transverse colon was then accamplished.
