Incidence of duodenal ulcers and gastric ulcers in a Western population: Back to where it started

BACKGROUND/OBJECTIVES: As recently as 40 years ago, a decline in the incidence Of peptic Ulcers was observed. The discovery of Helicobacter pylori had a further major impact on the incidence of ulcer disease. Our aim was to evaluate the trends in the incidence and bleeding complications of ulcer disease in the Netherlands. METHODS: From a computerized endoscopy database of a district hospital, the data of all patients who underwent upper gastrointestinal endoscopy from 1996 to 2005 were analyzed. The incidence of duodenal and gastric ulcers, with and without complications, were compared over time. RESULTS: Overall, 20,006 upper gastrointestinal endoscopies were performed. Duodenal ulcers were diagnosed in 696 (3.5%) cases, with signs of bleeding in 158 (22.7%). Forty,five (6.5%) of these ulcers were classified as Forrest I and 113 (16.2%) as Forrest II. Gastric ulcers were diagnosed in 487 cases (2.4%), with signs of bleeding in 60 (12.3%). A Forrest I designation was diagnosed in 19 patients (3.9%) and Forrest 2 in 41 patients (8.4%). The incidence Of gastric ulcers was stable over time, while the incidence of duodenal ulcers declined. CONCLUSIONS: The incidence of duodenal ulcer disease in the Dutch Population is steadily decreasing over time. Test and treatment regimens for H pylori have possibly contributed to this decline. With a further decline in the prevalence of H pylori, the incidence of gastric ulcers is likely to exceed the incidence of duodenal ulcers in the very near future, revisiting a similar Situation that was present at the beginning of the previous century

Double-balloon enteroscopy in Crohn's disease patients suspected of small bowel activity: findings and clinical impact

It is estimated that 10-30% of patients with Crohn's disease (CD) have small bowel (SB) involvement, but the exact frequency and clinical relevance of these findings is unknown. Double-balloon enteroscopy (DBE) enables endoscopic visualization of the SB. In this study we evaluated whether DBE is a feasible technique for detection of CD localized in the SB in CD patients with clinical suspicion of SB lesions and whether these findings have clinical impact. Retrospectively we analyzed 52 DBE procedures in 40 CD patients (16 males, mean age 40 years, mean duration of CD 15 years). Included patients had clinical suspicion of small bowel CD activity, including persistent abdominal discomfort (n = 27), iron deficiency anemia (n = 9) and/or hypomagnesemia (n = 4). Active small bowel CD was found in 24 (60%) patients, leading to a change in therapy in 18 patients (75%). After a mean follow-up of 13 months, 15 (83%) had persistent clinical improvement with a significant drop of mean CDAI from 178 to 90, after a mean follow-up of 13 months. DBE is a useful diagnostic tool for the evaluation of SB lesions in CD patients. The significance of these findings is emphasized by the fact that adjustment of therapy in the majority of these patients leads to significant and sustained clinical improvement

A cost-benefit analysis of endoscopy reporting methods: handwritten, dictated and computerized

Gastrointestinal endoscopy investigations are frequently requested by gastroenterologists, general practitioners and other physicians. In addition to the classic methods of report writing, several electronic endoscopic report systems are currently available. The aim of the study was to evaluate the costs of three different ways of producing reports; by hand, by dictation, or by computer

Multicenter study evaluating factors for stent patency in patients with malignant biliary strictures: development of a simple score model

Background Self-expanding metal stents (SEMS) are known to have a significantly higher patency rate than plastic stents. We aimed to identify prognostic factors, besides stent type, for stent patency and to develop a score model that could further aid in guiding stent choice for the palliation of a malignant biliary stricture. Methods A retrospective multicenter study was conducted. Data on consecutive patients who had a stent placed between January 2002 and July 2009 were collected. Cumulative stent occlusion rates were analyzed by Kaplan-Meier curves and log rank testing, and prognostic factors were assessed by Cox regression analysis. Results A total of 690 stents (512 plastic stents, 174 SEMS) were endoscopically placed in 390 patients. At 8 weeks, stent occlusion had occurred in 32% of the plastic stents and 11% of the SEMS. Multivariate analysis indicated that plastic stents (hazard ratio [HR] 2.5, 95% confidence interval [CI] 1.9-3.5), a tight stricture requiring preceding dilation (HR 1.8, 95% CI 1.3-2.5), and a high initial bilirubin level (>50 mu mol/L (HR 1.3, 95% CI 1.0-1.7) were independently associated with an increased risk of stent occlusion. A score model based on these 3 factors was able to distinguish between stent procedures with a relatively high and low risk of stent occlusion (median 14 vs. 26 weeks, respectively). Conclusion Besides plastic stents, stricture severity requiring preceding dilation, and initial higher bilirubin level were associated with a shorter period of stent patency. A simple score model based on these factors was able to predict stent occlusion and may aid in choosing the most appropriate stent type in individual patients
