RESUMEN
BACKGROUND: Capsule endoscopy (CE) is a new diagnostic tool for the study of patients with suspected small bowel pathology. The aim of the study was to clarify the usefulness of CE in the group of patients with obscure (overt / occult) gastrointestinal (GI) bleeding. PATIENTS AND METHODS: Thirty patients (14 men, 16 women, mean age 50 years, range 9 -79 years) were enrolled in the study. All of them undergone non-diagnostic esophagogastroduodenoscopy, colonoscopy and barium follow-through of the small bowel. All patients underwent capsule endoscopy. Fourteen patients had overt and sixteen occult bleeding. The single senior endoscopist interpreted CE findings in an unblinded manner. RESULTS: CE identified a source of bleeding in 14/30 patients (46.6%). Lesions identified were: tumors in five pts, vascular lesions, Crohnzs disease and Meckelzs diverticulum in two pts and fresh bleeding, segmental celiac disease and colonic diverticulosis in one patient each. CE identified a source of bleeding in 9/14 (64.3%) of patients with ongoing overt bleeding and in only 5/16 (31.3%) of patients with occult bleeding. The positive suspicious findings were seen in 6/30 (20%) of patients (2/14 with overt bleeding and 4/16 with occult bleeding. In 3/14 (21.4%) with overt and 7/16 (43.7%) with occult bleeding findings on CE were negative. All patients with negative findings on follow-up remained asymptomatic for one year. Capsule retention because of unsuspected stenosis occurred in a single patient and required surgery, which resolved the problem. CONCLUSION: CE is an effective diagnostic tool for patients with obscure GI bleeding. It is safe and painless technique which can diagnose the bleeding site beyond the reach of conventional endoscopy. The best candidates for the procedure are those with ongoing and overt bleeding.

INTRODUCTION: Successful endoscopic sclerotherapy is effective in securing hemostasis for bleeding lesions and remains the first line and only needed therapy for most of the patients (pts), but bleeding reoccurs in 10% to 30% pts, and 4% to 14% of the pts die after acute nonvariceal upper gastrointestinal bleeding (UGIB). The need for hospitalization and its duration for all the bleeding pts is still a controversial question. AIM: To create the simple scoring system able to determine low risk pts for rebleeding and mortality by establishing the relative importance of risk factors for rebleeding and mortality after successful endoscopic sclerotherapy of acute nonvariceal UGIB. PATIENTS AND METHODS: Prospective study included 3 15 pts who where admitted to hospital because of acute nonvariceal UGIB. All of them underwent gastroscopy with successful sclerotherapy within 12 hours after the admission. We investigated the episode of rebleeding and death during the initial hospitalization, and analyzed the following parameters: age, gender, drug intake, shock, bleeding stigmata, location of bleeding lesion and comorbidity. RESULTS: Rebleeding occurred in 53 pts (16.8%) and was determined by shock, bleeding stigmata and comorbidity. Eleven pts (3.5%) died and shock, rebleeding and comorbidity were all independent, statistically significant predictors of pts' mortality. The numerical scores for determination of pts with different risk levels for rebleeding and mortality have been developed using the significant predictors of rebleeding and death. The score values for rebleeding ranged from 3 to 9 and pts with values < or = 4 had low risk of rebleeding. We identified 59 pts (18.7% of all) with score for rebleeding < or = 4. Score values for mortality risk ranged from 3 to 8 and the values < 5 revealed negligible risk of death. In our group we found 290 pts (92.1% of all) with low mortality score values. CONCLUSION: Following the successful initial endoscopic sclerotherapy, these scores can help to identify pts with low risk of rebleeding and negligible risk of death, so they can be treated as outpatients.

BACKGROUND: There are conflicting reports concerning the prevalence of Helicobacter pylori infection in patients with inflammatory bowel diseases: some studies connected Sulphasalazine therapy and lower incidence of Helicobacter pylori infection, but others showed lower prevalence of Helicobacter pylori infection in inflammatory bowel diseases despite the choice of therapy. CASE REPORT: A 28-year-old male patient presented in January 1996 with the symptoms of ulcer like dyspepsia. There was no significant abnormality on physical examination, laboratory testing and abdominal ultrasound. Histology examination of the biopsy specimen taken during the upper endoscopy revealed Helicobacter pylori associated active gastritis only in the corporal part of the stomach. After two weeks eradication therapy (Omeprazole, Amoxicillin) he was well. Three months later, at the control endoscopy, granulomatous gastritis of the corporal localization was detected, without Helicobacter pylori present. Antral mucosa appeared normal, both, on endoscopy and histology examination. In July 1996 he started with cramping abdominal pain, mild periodical fever and episodes of watery diarrhea. In laboratory results we found nonspecific signs of inflammation. We repeated upper endoscopy, colonoscopy and enteroclysis--with evidence of segmental stenotic lesions of the upper part of ileum and jejunum. Again, we confirmed granulomatous gastritis and small granuloma in the proximal jejunum. After starting the 5-ASA therapy in combination with Metronidazol, patient was better clinical condition, and laboratory results were normal. We suggested mesalamine maintenance therapy 1 gr. every day, and three years later he is well, in clinical remission of Crohn's disease. CONCLUSION: The clinical course of the Crohn's disease maybe "sui generis" connected with Helicobacter pylori infection- but the exact mechanisms remain to be discovered.
