Abstract
OBJECTIVES To evaluate the effect of Helicobacter pylori (H. pylori) eradication on ulcer bleeding recurrence in a prospective, long-term study including 1,000 patients. METHODS Patients with peptic ulcer bleeding were prospectively included. Prior non-steroidal anti-inflammatory drug (NSAID) use was not considered exclusion criteria. H. pylori infection was confirmed by rapid urease test, histology, or (13)C-urea breath test. Several eradication therapies were used. Subsequently, ranitidine 150 mg o.d. was administered until eradication was confirmed by (13)C-urea breath test 8 weeks after completing therapy. Patients with therapy failure received a second, third, or fourth course of eradication therapy. Patients with eradication success did not receive maintenance anti-ulcer therapy and were controlled yearly with a repeat breath test. NSAID use was not permitted during follow-up. RESULTS Thousand patients were followed up for at least 12 months, with a total of 3,253 patient-years of follow-up. Mean age 56 years, 75% males, 41% previous NSAID users. In all, 69% had duodenal ulcer, 27% gastric ulcer, and 4% pyloric ulcer. Recurrence of bleeding was demonstrated in three patients at 1 year (which occurred after NSAID use in two cases, and after H. pylori reinfection in another one), and in two more patients at 2 years (one after NSAID use and another after H. pylori reinfection). The cumulative incidence of rebleeding was 0.5% (95% confidence interval, 0.16-1.16%), and the incidence rate of rebleeding was 0.15% (0.05-0.36%) per patient-year of follow up. CONCLUSION Peptic ulcer rebleeding virtually does not occur in patients with complicated ulcers after H. pylori eradication. Maintenance anti-ulcer (antisecretory) therapy is not necessary if eradication is achieved. However, NSAID intake or H. pylori reinfection may exceptionally cause rebleeding in H. pylori-eradicated patients.

Abstract
AIM Long-term results of biofeedback for faecal incontinence are controversial. Moreover, its value compared with standard care has been recently questioned. The study aimed to analyse the long-term efficacy of biofeedback therapy for faecal incontinence to formed stool and to compare it with no treatment. METHOD Seventy-nine patients with faecal incontinence to solid stool were evaluated at baseline and 1, 6, 36 and 60 months after treatment. To compare the long-term results with no treatment, 40 patients initially evaluated but not referred for therapy were used as controls. RESULTS More than 80% of patients recovered continence or had a reduction in the number of episodes of incontinence greater than 75% at 1, 6, 36 and 60 months, indicating that the success rate of biofeedback was maintained over time. At 60 months, 86% of patients treated with biofeedback were fully continent or had a > 75% reduction in the number of incontinent episodes compared to 26% of the untreated patients (P < 0.001). CONCLUSION Biofeedback therapy is effective in patients with faecal incontinence to formed stool compared with no treatment. Overall, clinical improvement is maintained in the long term.

Abstract
BACKGROUND Th1 and Th17 cells have been implicated in Crohn's disease (CD) pathophysiology and may play a role in disease persistence. Aim To determine Th1 and Th17 responses in intestine and peripheral blood of early (<32 weeks since initial symptoms) and late (>2 years) CD patients. METHODS Cytokine mRNA in intestinal biopsies was determined by RT-PCR. Cytokine concentration in culture was measured by ELISA and cytokine-producing cells were identified by intracellular staining. RESULTS The inflamed mucosa showed significantly increased IL-17 mRNA levels compared with non-inflamed areas, both in early and late CD patients. However, only patients with late (n = 12), but not early (n = 9), active disease showed increased IL-17 production, as well as a significantly higher percentage of IL-17(+)CD4(+) cells in blood, compared with controls (n = 12) or patients in remission (n = 13). Moreover, cultured peripheral CD4(+) cells from late active CD patients presented significantly higher percentages of IL-17(+), IL-22(+) and IFN-gamma(+) and a significantly increased production of IL-17 and IL-22, but not IFN-gamma(+). CONCLUSIONS Increased IL-17 gene transcription is common to early and late CD mucosa. However, exacerbated Th17 responses in the peripheral blood appear only in late disease. We propose that this population may constitute a mechanism of perpetuating the disease.

Abstract
BACKGROUND The risks and benefits of coxibs, non-steroidal anti-inflammatory drugs (NSAIDs), and aspirin treatment are under intense debate. OBJECTIVE To determine the risk of peptic ulcer upper gastrointestinal bleeding (UGIB) associated with the use of coxibs, traditional NSAIDs, aspirin or combinations of these drugs in clinical practice. METHODS A hospital-based, case-control study in the general community of patients from the National Health System in Spain. The study included 2777 consecutive patients with endoscopy-proved major UGIB because of the peptic lesions and 5532 controls matched by age, hospital and month of admission. Adjusted relative risk (adj RR) of UGIB determined by conditional logistic regression analysis is provided. RESULTS Use of non-aspirin-NSAIDs increased the risk of UGIB (adj RR 5.3; 95% confidence interval (CI) 4.5 to 6.2). Among non-aspirin-NSAIDs, aceclofenac (adj RR 3.1; 95% CI 2.3 to 4.2) had the lowest RR, whereas ketorolac (adj RR 14.4; 95% CI 5.2 to 39.9) had the highest. Rofecoxib treatment increased the risk of UGIB (adj RR 2.1; 95% CI 1.1 to 4.0), whereas celecoxib, paracetamol or concomitant use of a proton pump inhibitor with an NSAID presented no increased risk. Non-aspirin antiplatelet treatment (clopidogrel/ticlopidine) had a similar risk of UGIB (adj RR 2.8; 95% CI 1.9 to 4.2) to cardioprotective aspirin at a dose of 100 mg/day (adj RR 2.7; 95% CI 2.0 to 3.6) or anticoagulants (adj RR 2.8; 95% CI 2.1 to 3.7). An apparent interaction was found between low-dose aspirin and use of non-aspirin-NSAIDs, coxibs or thienopyridines, which increased further the risk of UGIB in a similar way. CONCLUSIONS Coxib use presents a lower RR of UGIB than non-selective NSAIDs. However, when combined with low-dose aspirin, the differences between non-selective NSAIDs and coxibs tend to disappear. Treatment with either non-aspirin antiplatelet or cardioprotective aspirin has a similar risk of UGIB.

Abstract
BACKGROUND/AIMS Despite the existence of published recommendations, various studies of antibiotic prophylaxis have reached conflicting conclusions, and controversy exists regarding the role of antibiotic prophylaxis in ERCP. The aim of this study was to analyze the efficacy of the intramuscular administration of clindamicine and gentamicine before ERCP. METHODOLOGY Sixty-one consecutive patients referred for ERCP were prospectively randomized to receive either clindamicine 600mg and gentamicine 80mg, both intramuscularly one hour before the ERCP (group I; 31 patients) or not (group II; 30 patients). Two blood samples were obtained from every patient (just before endoscopy and within 5 minutes of withdrawal of the endoscope) and were incubated for 7 days and examined daily for growth of bacteria. Patients were closely monitored for 7 days after endoscopy to detect the development of infectious complications. RESULTS Only 7 cultures from 7 patients were positive. Four were obtained post-ERCP (two patients in group I and two in group II) and the remaining three before endoscopy. The post-ERCP isolated bacteria were: Streptococcus mitis, Peptoestreptococcus anaerobious, Moraxella spp and Escherichia coli. Two patients, one from each group, developed post-ERCP cholangitis that were solved with medical treatment. CONCLUSIONS Our findings indicate that ERCP induce bacteremia in a small group of patients and suggest that prophylactic administration of clindamicine plus gentamicine does not reduce the incidence of bacteremia and cholangitis, and do not support the routine use of prophylactic antibiotics prior to ERCP.

Abstract
BACKGROUND The natural history of the irritable bowel syndrome is poorly understood. AIM To assess the clinical course of the irritable bowel syndrome and the factors that might predict it. METHODS An observational prospective study, involving 400 irritable bowel syndrome patients meeting Rome II criteria. Symptoms were recorded in a diary over four non-consecutive months (1, 4, 7 and 10). Demographic data, associated disorders, psychological status and health-related quality of life were obtained. RESULTS At 1-year follow-up, half of the patients and half of their physicians considered irritable bowel syndrome to have improved, but improvement was minor. Diary data showed that, according to the type of symptom, improvement was small and quite different: diarrhoea in 19% of patients, abdominal pain frequency in 26%, constipation in 33% and abdominal pain intensity in 60%. Factors related to improvement at one year were: severe symptoms and poor health-related quality of life at first visit, irritable bowel syndrome-constipation, good improvement at 3 months, anxiety/depression, stress, symptoms related to meals and absence of comorbidity. By multivariate logistic regression, predictors were: severe basal symptoms and good improvement at 3 months (OR:CI 95%, 1.32:1.09-1.59 and 4.44:2.81-7.05). CONCLUSIONS At 1-year follow-up, half the patients and their physicians considered the irritable bowel syndrome to have had some improvement but, symptom diaries demonstrated that improvement was small and heterogeneous. Severe basal symptoms and improvement at 3 months were related to better prognosis.

Abstract
BACKGROUND The prevalence of gastro-oesophageal reflux disease (GERD), has not been characterized in Spain. Aim To measure the prevalence of GERD in Spain, and the factors associated with it, by means of a primary care-based study. METHODS An epidemiological, multicentre, cross-sectional, population-based study. A self-administered questionnaire was sent out to randomly selected patients. Data were statistically analysed to provide the prevalence of GERD and to compare it with that of gastro-oesophageal reflux symptoms. Factors associated with GERD were studied using logistic regression models. RESULTS The response rate was 45%. The prevalence of GERD was 15% (95% CI: 13.2-16.2). When compared with gastro-oesophageal reflux symptoms patients, those with GERD experienced more intense symptoms (moderate-severe: 35% vs. 8%, P < 0.001) and suffered heartburn more frequently both at day and night (48% vs. 25%, P < 0.001) and for longer period of times (69% vs. 62%, P = 0.057). A body mass index of >25% (odds ratio: 1.07; 95% CI: 1.03-1.11) was the only independent variable associated with GERD. The risk of suffering GERD increases by 7% for each kg/m(2) that the body mass index increases. CONCLUSIONS The prevalence of GERD among the Spanish population is 15%. Body mass index is the only risk factor significantly associated with GERD.

Abstract
INTRODUCTION Pyrosis symptoms and their impact on the quality of life related with health (QLRH) are frequently evaluated in clinical trials. When a questionnaire is translated into a language other than the original, it is necessary to have a linguistic validation, although this is not sufficient unless the psychometric characteristics have been verified. This study aims to document the psychometric characteristics of the translation to Spanish of the gastrointestinal symptoms rating scale (GSRS) and quality of life in reflux and dyspepsia (QOLRAD). MATERIAL AND METHOD One hundred fifty eight patients with pyrosis symptoms (age: 51.0; SD: 16.3 years; men: 42.4%) completed the translation to Spanish of the GSRS, the pyrosis version of the QOLRAD, the Short-Form-36 (SF-36) and the hospital of anxiety and depression (HAD) scale. Seventy six patients were given an appointment for a second visit after one week, to fill out the GSRS and QOLRAD again. RESULTS The reliability of the internal consistence of the GSRS was 0.59-0.83 and that of the QOLRAD: 0.87-0.95, and test-retest reliability of the GSRS was 0.44-0.63 and QOLRAD: 0.77-0.85. Score of the important domains of the GSRS "reflux", "abdominal pain" and "indigestion" and above all those of the QOLRAD correlated significantly. The domain "abdominal pain" of the GSRS had a strong correlation (negative) with the relevant domains of the SF-36. The QOLRAD domains significantly correlated with all the related domains of the SF-36. CONCLUSIONS The psychometric characteristics of the translation to Spanish of the GSRS and QOLRAD were good, with satisfactory reliability and validity. However, the test-retest reliability of the "reflux" domain of the GSRS was not optimum.

Abstract
BACKGROUND AND AIMS Increased pancreatitis associated protein (PAP) mRNA has been reported in active inflammatory bowel disease (IBD). The aims of the current study were to characterise PAP production in IBD and the effects of PAP on inflammation. PATIENTS AND METHODS Serum PAP levels were determined in healthy controls (n = 29), inflammatory controls (n = 14), and IBD patients (n = 171). Ex vivo PAP secretion in intestinal tissue was measured in 56 IBD patients and 13 healthy controls. Cellular origin of PAP was determined by immunohistochemistry. The effects of exogenous PAP on nuclear factor kappaB (NFkappaB) activation, proinflammatory cytokine production, and endothelial adhesion molecule expression were also analysed ex vivo. RESULTS Patients with active IBD had increased serum PAP levels compared with controls, and these levels correlated with clinical and endoscopic disease severity. Ex vivo intestinal PAP synthesis was increased in active IBD and correlated with endoscopic and histological severity of inflammatory lesions. PAP localised to colonic Paneth cells. Incubation of mucosa from active Crohn's disease with PAP dose dependently reduced proinflammatory cytokines secretion. PAP prevented TNF-alpha induced NFkappaB activation in monocytic, epithelial, and endothelial cells and reduced proinflammatory cytokine mRNA levels and adhesion molecule expression. CONCLUSIONS PAP is synthesised by Paneth cells and is overexpressed in colonic tissue of active IBD. PAP inhibits NFkappaB activation and downregulates cytokine production and adhesion molecule expression in inflamed tissue. It may represent an anti-inflammatory mechanism and new therapeutic strategy in IBD.

Abstract
BACKGROUND The demand for gastrointestinal endoscopy is increasing in most developed countries, resulting in an important rise in overall costs and waiting lists for endoscopic procedures. Therefore, adherence to appropriate indications for these procedures is essential for the rational use of finite resources in an open-access system. AIM To assess indications and appropriateness of colonoscopy according to the European Panel on the Appropriateness of Gastrointestinal Endoscopy (EPAGE) criteria. METHODS From May to June 2004, all consecutive patients referred to our Unit for open-access colonoscopy were considered for inclusion in this prospective study. Appropriateness of each colonoscopy was established according to the EPAGE criteria. In order to evaluate whether appropriateness of use correlated with the diagnostic yield of colonoscopy, relevant endoscopic findings were also recorded. RESULTS A total of 350 consecutive patients were included in the study. In 38 of them, the colonoscopy indication was not listed in the EPAGE guidelines and, consequently, they were not evaluated. In the remaining 312 patients, the indication for the procedure was considered inappropriate in 73 (23%) patients. Both referring doctor characteristics (specialty and health care setting) and patient data (age) correlated with appropriateness of endoscopy. The diagnostic yield was significantly higher for appropriate colonoscopies (42%) than in those judged inappropriate (21%) (P = 0.001). CONCLUSIONS A noteworthy proportion of patients referred for colonoscopy to an open-access endoscopy unit are considered inappropriate because of their indication, with significant differences among specialties. These results suggest that implementation of validated guidelines for its appropriate use could improve this situation and, considering the correlation between appropriateness and diagnostic yield, even contribute to improve the prognosis of patients with colorectal diseases.

Abstract
BACKGROUND The applicability of laparoscopic surgery in the treatment of colorectal diseases is still controversial. Early reports on laparoscopic-assisted colectomy in patients with colon cancer suggested that it minimizes surgical trauma, decreases perioperative complications, and leads to a more rapid recovery. To our knowledge, no previous studies have compared the laparoscopic vs the open approach in rectal cancer. The aim of this paper was to assess the results of laparoscopic techniques in patients with rectal cancer. METHODS From March 1998 to February 2003, all patients admitted to our unit with adenocarcinoma of the rectum were evaluated for surgery by the laparoscopic approach. RESULTS A total of 220 patients with a mean age of 67.3 years were included in the study. One hundred thirty patients (59%) were treated with neoadjuvant chemoradiotherapy. In >75% of the patients, a surgical procedure with sphincter preservation was performed. The rate of conversion to the open approach was 20%. Ten patients had intraoperative complications. Fifty-eight patients (26.3%) developed postoperative complications. The length of hospital stay was 6.8 days. The distribution of tumor stages was as follows: stage I, 16.81%; stage II, 33.6%; stage III, 26.36%; stage IV, 19.09%. The mean number of lymph nodes was 13.8. The incidence of local relapse was 5.3%, with a follow-up of 18 months. CONCLUSION Laparoscopic surgery can be safely performed in patients with adenocarcinoma of the rectum with good short-term results. Randomized controlled trials are needed to confirm these results.

Abstract
BACKGROUND The identification and treatment of lesions located in the small intestine in obscure gastrointestinal bleeding is always a clinical challenge. AIM To examine prospectively the diagnostic precision and the clinical efficacy of capsule endoscopy compared with push enteroscopy in obscure gastrointestinal bleeding. METHODS Forty-two patients (22 men and 20 women) with obscure gastrointestinal bleeding (overt bleeding in 26 cases and occult blood loss with chronic anaemia in 16) and normal oesophagogastroduodenoscopy and colonoscopy were analysed. All patients were instructed to receive the capsule endoscopy and push enteroscopy was performed within the next 7 days. Both techniques were blindly performed by separate examiners. The diagnostic yield for each technique was defined as the frequency of detection of clinically relevant intestinal lesions carrying potential for bleeding. RESULTS A bleeding site potentially related to gastrointestinal bleeding or evidence of active bleeding was identified in a greater proportion of patients using capsule endoscopy (74%; 31 of 42) than enteroscopy (19%; eight of 42) (P = 0.05). The most frequent capsule endoscopy findings were: angiodysplasia (45%), fresh blood (23%), jejunal ulcers (10%), ileal inflammatory mucosa (6%) and ileal tumour (6%). No additional intestinal diagnoses were made by enteroscopy. In seven patients (22%), the results obtained with capsule endoscopy led to a successful change in the therapeutic approach. CONCLUSIONS Compared with push enteroscopy, capsule endoscopy increases the diagnosis yield in patients with obscure gastrointestinal bleeding, and allows modification on therapy strategy in a remarkable proportion of patients.

Abstract
INTRODUCTION The identification and localization of lesions located in the small intestine that may provoke gastrointestinal bleeding is difficult. OBJECTIVE To analyze the role of capsule endoscopy in patients with obscure digestive bleeding and to compare the results obtained with those of enteroscopy. PATIENTS AND METHODS Twenty-one patients with obscure digestive bleeding (acute hemorrhage in 11 patients and chronic anemia in 10) and normal total fibergastroscopy and fibrocolonoscopy were analyzed. All patients were instructed to receive the capsule and enteroscopy was performed after 1 week. The results obtained using both procedures were independently compared and without knowledge of the results of the other procedure. RESULTS Visualization of findings potentially related to gastrointestinal bleeding was significantly greater (p < 0.05) using the capsule (14 of 21 patients [66%]) than with enteroscopy (4 of 21 patients [19%]). The most frequent lesions were angiodysplasias and jejunal ulcers. In 4 patients, the results obtained led to a change in therapeutic approach. One patient with jejunal stenosis and two with ileal lesions underwent surgery, which confirmed the diagnosis of Crohn's disease in the first patient and carcinoid tumor in the remaining two. Another patient with evidence of angiodysplasia and bleeding was effectively treated with Argon-beam during enteroscopy. The capsule was well tolerated in all patients. In the patient with jejunal stenosis, capsule extraction was required during surgery. CONCLUSIONS Capsule endoscopy allows adequate visualization of the entire small intestine and its diagnostic efficacy is greater than that of enteroscopy in patients with obscure digestive bleeding. Moreover, in our series, this procedure allowed modification of therapy in one out of every five patients.

Abstract
OBJECTIVE To describe the characteristics of patients included in the pancreatic tumor registry of the Hospital Clínic of Barcelona. PATIENTS AND METHOD All patients with pancreatic tumors attended between July 1990 and March 2003 were registered. Data collection included: age, gender, date of diagnosis, diagnosis, histology, size, location and tumor stage, and treatment. The correlation between tumor stage and age, date of diagnosis, and tumor location was also evaluated. RESULTS Six hundred thirty patients with pancreatic tumors were included, representing an incidence of 60 patients/year. The mean age was 66 years and the male-to-female ratio was 1,18:1. The most frequent lesion was malignant tumor of the pancreas (92%), and the most frequent histological type was pancreatic ductal adenocarcinoma (73%). The most frequent location was the head of the pancreas (64%). In 28% of the patients, pancreatic cancer was diagnosed in stage I and II. Resection was performed in 31% of patients, whereas 48% of the patients received no treatment. The ratio between local (stage I)/disseminated (stage IV) disease was 0,34. The ratio between stage I/IV increased with age, diagnosis prior to 1994, and tumor location in the head of the pancreas. CONCLUSION Hospital tumor registries can be used to define the profile of the attended population, which can help to delineate the best diagnostic-therapeutic strategy and can be useful in clinical research.

Abstract
INTRODUCTION The clinical and socioeconomic burden of gastroesophageal reflux disease (GERD) is considerable. AIM The aim of this study was to describe the impact of heartburn on patients' health-related quality of life (HRQL) in Spain, using validated generic and disease-specific instruments to measure patient-reported outcomes. PATIENTS AND METHODS Patients with symptoms of heartburn completed the Spanish versions of the Gastrointestinal Symptom Rating Scale (GSRS), the Quality of Life in Reflux and Dyspepsia questionnaire (QOLRAD), the Short Form-36 (SF-36) and the Hospital Anxiety and Depression (HAD) scale. The frequency and severity of heartburn in the previous 7 days were also recorded. RESULTS One hundred fifty-eight patients completed the assessments (mean age: 51 years, SD = 16; 58% female). Sixty-one percent of the patients had moderate symptoms and 73% had symptoms on three or more days in the previous week. Patients were most bothered by symptoms of reflux (mean GSRS score of 3.8 on a scale of 1 [not bothered] to 7 [very bothered]), abdominal pain (3.1) and indigestion (3.1). As a result of their symptoms, patients experienced problems with food and drink (mean QOLRAD score of 4.5 on a scale of 1 to 7, where 1 represents the most severe impact on daily functioning), impaired vitality (4.7) and emotional distress (4.8). This led to impaired overall HRQL across all domains (mean SF-36 score of this heartburn population compared with a general population in Spain). The HAD scale showed that 28% of patients were anxious and 13% were depressed. CONCLUSION There is consistent evidence that GERD substantially impairs all aspects of HRQL.

Abstract
INTRODUCTION Studies examining the relationship between stress secondary to adverse life events (ALE) and inflammatory bowel disease (IBD) have produced controversial data. The aim of this study was to explore the subjective perception of this relationship in IBD patients. PATIENTS AND METHODS Seventy consecutive patients suffering from IBD (40 Crohn's disease, 30 ulcerative colitis) were assessed using a self-rating questionnaire related to demographic variables, clinical characteristics, subjective perception of the influence of ALE on the course of IBD, psychiatric background, and the HAD scale. The results of this scale were compared with a group of 25 relatives. RESULTS Forty-two patients (60%) perceived that there was relationship between ALE and the onset of their disease, forty-nine (70%) between ALE and the increasing IBD symptoms severity, and fifty-one patients (72.9%) with disease activity. Sixteen of the patients (22.9%) had been visited by a psychiatrist during relapses of IBD. Twenty-five patients (42.4%) reached a score of 11 or higher on the depression or anxiety subscales of the HAD, indicating a probable psychological disorder. CONCLUSIONS IBD patients perceive a strong relationship between ALE and the course of IBD. We have found a high prevalence of anxiety and depression symptoms in these patients. If this observation is confirmed with objective measurements, it will be important to consider psychiatric intervention for these patients.

Abstract
AIM To establish the usefulness of KRAS mutational analysis in the diagnosis of pancreatic adenocarcinoma by comparing this technique with conventional cytology in aspirates obtained by endosonography-guided fine-needle aspiration. METHODS All consecutive patients with pancreatic focal lesions undergoing endosonography-guided fine-needle aspiration were included. Samples were obtained with the concurrence of an attendant cytopathologist. Detection of codon-12 KRAS mutations was performed by the restriction fragment length polymorphism-polymerase chain reaction method. The effectiveness of conventional cytology, KRAS mutational analysis and their combination was established with respect to the definitive diagnosis. A cost-effectiveness analysis was also performed. RESULTS Thirty-three patients had pancreatic adenocarcinoma and 24 patients had other lesions. A total of 136 samples was obtained. In patients in whom specimens were adequate (93% for cytology; 100% for mutational analysis), the specificity of both techniques was 100%, whereas the sensitivity favoured cytology (97% vs. 73%). When inadequate samples were considered as misdiagnosed, a combination of both techniques reached the highest overall accuracy (cytology, 91%; mutational analysis, 84%; combination of both, 98%). CONCLUSIONS Cytology from aspirates obtained by endosonography-guided fine-needle aspiration is the most precise single technique for the diagnosis of pancreatic adenocarcinoma. However, when adequate specimens are not available to reach a cytological diagnosis, the addition of KRAS mutational analysis represents the best strategy.

Abstract
BACKGROUND Crohn's disease is a heterogeneous disorder with polygenic inheritance. AIM To assess the effect of the 4G/5G polymorphism of the type-1 plasminogen activator inhibitor (PAI-1) gene, the major inhibitor of fibrinolysis, on Crohn's disease susceptibility and phenotype. METHODS One hundred and fifty-seven patients with Crohn's disease and 350 controls were included prospectively. Medical records were reviewed to determine changes in the Crohn's disease phenotype. The 4G/5G polymorphism was assessed by polymerase chain reaction techniques. RESULTS The frequencies of the 4G/4G, 4G/5G and 5G/5G genotypes were similar in patients with Crohn's disease and controls. The 4G/4G genotype (P < 0.0001; odds ratio, 4.84) and male sex (P = 0.009; odds ratio, 2.63) were independent risk factors for penetrating behaviour in Crohn's disease. Most Crohn's disease patients had a non-penetrating phenotype at diagnosis. The probability of development of a penetrating phenotype within 5 years of diagnosis was higher in patients with the 4G/4G genotype (72% vs. 19%, P < 0.0001). CONCLUSIONS The 4G/4G genotype of the PAI-1 gene does not influence Crohn's disease susceptibility, but increases by five-fold the probability of penetrating behaviour. Most patients with the 4G/4G genotype have a non-penetrating phenotype at diagnosis, but develop a penetrating behaviour within 5 years. Genotyping the 4G/5G polymorphism may be useful for the identification of a sub-group of patients with aggressive Crohn's disease, who might benefit from specific therapy.

Abstract
INTRODUCTION Because of the increased complexity of the diagnostic-therapeutic approach to colorectal cancer (CRC), these patients should be managed in specialized multidisciplinary units. The aim of this study was to evaluate the efficacy and efficiency of a CRC unit (CRCU) in the diagnostic-therapeutic management of these patients. PATIENTS AND METHODS Two groups of 50 patients with colon cancer treated in our center before and after the implementation of the CRCU were selected. Fulfillment with the protocol in terms of tumoral staging, surgical and adjuvant treatment, follow-up, interval until treatment, hospital stay, morbidity and early mortality, and the overall duration of the diagnostic-therapeutic process was analyzed. In addition, clinical workload was evaluated and a cost-minimization analysis was performed. RESULTS The CRCU reduced the interval until surgery (20.3 12.0 vs 28.0 20.4 days; p = 0.05), hospital stay (9.8 7.7 vs 14.5 9.3 days: p = 0.01), the time to the start of adjuvant treatment (29.4 10.2 vs 39.7 19.8 days; p = 0.03) and the overall duration of the process (60.4 23,8 vs 82.1 46.1 days; p = 0.05), representing a saving of 978.85 E per patient. This improvement took place despite an increase in clinical workload (24% in 5 years in relation to the number of admissions) and had no effect on morbidity (26 vs 24%; NS) or immediate mortality (6 vs 4%; NS). CONCLUSION Specialized multidisciplinary units increase the efficacy and efficiency of the management of patients with CRC.

Abstract
BACKGROUND/AIMS Endoscopic procedures such as sphincterotomy and endobiliary stenting have proved useful to solve postoperative bile leakage. We have assessed the outcome of a series of such patients initially treated with endoscopic sphincterotomy, having reserved stent placement for treatment failures only. METHODOLOGY Twenty-five consecutive patients referred for endoscopic assessment of postoperative bile leaks and fistulas after cholecystectomy (n = 15), orthotopic liver transplantation (n = 9) and hepatic resection due to cystic hydatid disease (n = 1) underwent endoscopic retrograde cholangiopancreatography and sphincterotomy using a standard papillotome. Sphincterotomy was followed by stone extraction using a Dormia basket if common bile duct lithiasis were present. RESULTS Bile leaks healed early after endoscopic sphincterotomy in 22 out of 25 patients (88%). Common bile duct stones were also retrieved in 6 of these patients. Bile duct stenosis due to surrounding pancreatic inflammation was demonstrated in two of the patients in which sphincterotomy failed to stop bile leakage. CONCLUSIONS Endoscopic sphincterotomy alone should at present be considered a highly effective treatment to resolve postsurgical bile leaks unless bile strictures are present.

Abstract
UNLABELLED No data are available on the use of the Internet by Spanish patients with chronic diseases. AIM To determine the extent to which patients with inflammatory bowel disease (IBD) in Barcelona (Spain) make use of the Internet and the relationship between Internet use and demographic characteristics. METHOD A questionnaire on Internet use was administered to 200 patients attending an information session on IBD organized by the Gastroenterology Department of a university referral hospital in the city of Barcelona. RESULTS Replies were received from 86% of those surveyed. The mean age was 40 years and 60% were women. Sixty-eight percent had home computers and 49% had an Internet connection. Forty-four percent sporadically or regularly obtained information on IBD from the web. A positive correlation was found between availability and Internet use and young age and higher educational level. No differences were found between men and women. Eighty-four percent expressed interest in having a web site on IBD supported by the physicians of their referral center and 65% were prepared to pay a subscription for this service. CONCLUSION Patients with IBD from Barcelona frequently looked for information on their disease on the Internet and were receptive to initiatives concerning electronic information from physicians of their local referral center.

Abstract
BACKGROUND The salvage of a leaking rectal anastomosis has been reported in selected cases. Herein we present our experience in the management of rectal anastomotic dehiscence by minimally invasive techniques. METHODS A total of 94 patients underwent anterior rectal resection for rectal cancer in an 18-month period. The operation was laparoscopic-assisted in 76 cases (81%). RESULTS Clinical anastomotic dehiscences occurred in 10 cases (10.6%). Conservative therapy, including the percutaneous drainage of pelvic abscesses, was successful in three cases. Among the seven patients who required reoperation, the anastomosis was taken down in only one case. In four of these cases, the reoperation was performed laparoscopically, including peritoneal lavage and the creation of a diverting stoma. There were no complications resulting from the use of laparoscopy in the early postoperative period. Closure of the stoma was possible in eight patients. CONCLUSIONS The salvage of a leaking rectal anastomosis is feasible in the vast majority of these cases (80%). The combination of laparoscopy and interventional radiology is a good alternative to laparotomy in patients who have had previous laparoscopic rectal excision.

Abstract
BACKGROUND An association between Helicobacter pylori infection and heart disease has been suggested. A potential mechanism may be inflammation-induced atherogenic changes of lipoproteins, but epidemiological studies have provided conflicting results. METHODS In a prospective multicentre study, 830 patients submitted for endoscopy and H. pylori testing were evaluated. Of the 686 H. pylori-positive patients, 487 received and 199 did not receive eradication treatment. Serum lipids and plasma fibrinogen were measured at baseline in all patients and 3 months later in those initially positive for H. pylori. RESULTS H. pylori had no influence on baseline lipid or fibrinogen levels. Increases in high-density lipoprotein cholesterol were observed in 368 patients who received eradication treatment and in 193 untreated patients: 0.06 mmol/L (P=0.000) and 0.07 mmol/L (P=0.009), respectively. Similar minor increases in total cholesterol and triglycerides occurred in both groups. Lipid changes were related to symptom relief and a reduction in smoking. Eradication therapy was associated with a minor decrease in plasma fibrinogen irrespective of the resolution of infection. CONCLUSIONS H. pylori has no influence on blood lipids or fibrinogen. Both the eradication of infection and symptomatic treatment without eradication are associated with minor lipid changes related to symptom relief and lifestyle modifications. Thus, the inflammatory changes associated with H. pylori are unlikely to affect lipoprotein or fibrinogen metabolism.

Abstract
BACKGROUND Endoscopic injection is widely used in the therapy of bleeding gastroduodenal ulcers, but its role in the management of bleeding Mallory-Weiss tears has not been properly assessed. METHODS Sixty-three patients undergoing emergency endoscopy in whom there was a high index of suspicion that a Mallory-Weiss tear was the source of bleeding were randomly assigned to undergo endoscopic injection therapy (epinephrine and polidocanol) or no endoscopic therapy in 2 university-affiliated hospitals. Rates of recurrent bleeding, transfusion requirements, complications, mortality, and length of hospital stay were determined for both groups of patients. RESULTS Bleeding recurred in 8 patients in the control group versus only 2 in the endoscopic treatment group (25.8% vs. 6.2%, p < 0.05). Hospital stay was longer for the control group (5.5 +/- 0.2, median 6.0, range 2.0-8.0 days vs. 3.4 +/- 0.2, median 3.0, range 2.0-6.0 days; p < 0.001). There was a trend toward a higher transfusion requirement after endoscopy in the control group versus the patients treated by injection (0.9 +/- 0.2, median 0.0, range 0.0-4.0 units vs. 0.2 +/- 0.1, median 0.0, range 0.0-2.0 units; p = 0.09). No complications or adverse events caused by endoscopic injection were noted. Two patients in the control group died of causes unrelated to bleeding. CONCLUSIONS Endoscopic injection therapy is a useful option in the management of patients with Mallory-Weiss syndrome at high risk for recurrent bleeding.

Abstract
BACKGROUND & AIMS The efficacy of hormonal therapy for recurrent bleeding from gastrointestinal angiodysplasia remains uncertain. We investigated the efficacy of long-term estrogen-progestagen therapy in the prevention of rebleeding from gastrointestinal angiodysplasia. METHODS Seventy-two noncirrhotic patients bleeding from gastrointestinal angiodysplasia confirmed by endoscopy or angiography were randomized to receive in double-blind conditions treatment with ethinylestradiol (0.01 mg) plus norethisterone (2 mg) (1 tablet/d), or placebo (1 tablet/d) for a minimum period of 1 year (range: 1-2 years). RESULTS Four patients could not be assessed because they did not attend the first follow-up visit. Failure of treatment occurred in 13 of 33 (39%) patients in the treatment group and in 16 of 35 (46%) patients in the placebo group (P = NS). No significant differences between groups were found according to number of bleeding episodes (0.7 +/- 1.0 vs. 0.9 +/- 1.5) and transfusional requirements (0.9 +/- 1.9 vs. 0.7 +/- 1.5 units). Treatment received was not an independent predictor for rebleeding prevention in the multivariate regression analysis. Severe adverse events (2 vs. 1) and mortality (0 vs. 1 patient, respectively) were similar between the treatment and placebo groups. CONCLUSIONS Continuous estrogen-progestagen treatment is not useful in the prevention of rebleeding from gastrointestinal angiodysplasia.

Abstract
UNLABELLED Laparoscopic surgery is associated with systemic and splanchnic hemodynamic alterations. Recent data suggest that small-dose dobutamine may attenuate the reduction in splanchnic blood flow associated with increments in intraabdominal pressure. We conducted this study to analyze the effects of dopamine and dobutamine on the hepatic circulation in this setting. Twenty-one pigs were anesthetized and mechanically ventilated. A flow-directed pulmonary artery and carotid artery catheters were inserted. Perivascular flow probes were placed around the main hepatic artery and the portal vein. CO2 was insufflated into the peritoneal cavity to reach an intraabdominal pressure of 15 mm Hg. After 60 min, animals received dopamine (5 microg x kg(-1) x min(-1); n = 8), dobutamine (5 microg x kg(-1) x min(-1); n = 8), or saline (n = 5) for 30 min. Pneumoperitoneum induced significant increases in heart rate, mean arterial pressure, and systemic vascular resistance, with decreases in cardiac output and hepatic artery and portal vein blood flows. Dobutamine infusion, in contrast to dopamine, corrected, at least in part, cardiac output, systemic vascular resistance, and hepatic artery blood flow alterations, but neither drug restored total hepatic blood flow. IMPLICATIONS Hepatic blood flow decreases during laparoscopic surgery. A small-dose infusion of neither dobutamine nor dopamine corrects the total hepatic blood flow impairment, but the former is able to restore the hepatic arterial blood supply in an animal model mimicking this condition.

Abstract
OBJECTIVES 1) To determine if endothelial expression of adhesion molecules involved in leukocyte recruitment is increased in the brain and other organs in four different models of experimental colitis, and 2) to investigate whether leukocyte infiltration occurs in the brain of colitic animals. METHODS Endothelial vascular cell adhesion molecule-1 (VCAM-1) and intercellular adhesion molecule-1 (ICAM-1) expression was quantified, using the dual radiolabeled antibody technique in rats with trinitrobenzenesulfonic acid (TNBS)-induced colitis, in mice with dextran sulfate sodium (DSS)-induced colitis, in SCID mice reconstituted with CD45RBhigh T-cells, and in IL-10-/- mice. Leukocyte infiltration in the brain of TNBS-induced colitic rats was assessed by myeloperoxidase activity and immunohistochemical staining with anti-CD45 monoclonal antibody. RESULTS Marked upregulation of brain endothelial VCAM-1 (2- to 5.5-fold) was consistently found in colitic animals in the four models studied. Brain VCAM-1 strongly correlated with colon VCAM-1 and colon weight. By contrast, upregulation of brain ICAM-1 in colitic animals was only observed in the CD45RBhigh transfer (3-fold) and the TNBS-induced (1.5-fold models). Heart and muscle VCAM-1 and ICAM-1 were not upregulated in colitic animals in the majority of models studied. There was no leukocyte infiltration into the brain of TNBS-induced colitic rats. CONCLUSIONS Our study demonstrates a marked and specific upregulation of endothelial VCAM-1 in the brain of colitic animals. This activation of cerebral endothelial cells was not associated with an infiltration of leukocytes into brain tissue.

Abstract
OBJECTIVE The purpose of our study was to compare the usefulness of hydrocolonic sonography and (99m)Tc-hexamethylpropyleneamine oxime (HMPAO)--labeled leukocyte scintigraphy in the examination of patients with inflammatory bowel disease, using precise sonographic criteria of bowel involvement. SUBJECTS AND METHODS Sixty-eight consecutive patients with active inflammatory bowel disease (34 ulcerative colitis and 34 Crohn's disease), 12 with inactive inflammatory bowel disease, and 10 control subjects were prospectively studied. Patients with active disease underwent clinical assessment, hydrocolonic sonography, scintigraphy, and colonoscopy within 72 hr, whereas patients with inactive disease and control subjects underwent clinical examination and hydrocolonic sonography. RESULTS Involvement of a colonic segment by active inflammatory bowel disease was best defined by mucosal thickness greater than 1.5 mm, bowel wall thickness greater than 4 mm, mucosal irregularity, or the absence of haustra; and involvement of the terminal ileum by bowel wall thickness greater than 4 mm. Using these criteria, hydrocolonic sonography had 100% sensitivity for identifying patients with active inflammatory bowel disease and a greater overall accuracy (87%) than scintigraphy (77%) in the assessment of disease extension. In addition, strong correlation was shown between a hydrocolonic sonography activity index and clinical and endoscopic activity indexes. CONCLUSION This prospective study provides precise sonographic criteria for the definition of bowel involvement by active inflammatory bowel disease. Hydrocolonic sonography has a greater accuracy than scintigraphy for assessing disease extension and activity. Therefore, hydrocolonic sonography should be considered a first-choice technique to complete the study of inflammatory bowel disease after confirmation of the diagnosis by histology.

Abstract
The aims of our study were to characterize the dose- and time-dependent changes in endothelial P-selectin expression and the role of this adhesion molecule as a mediator of radiation-induced inflammation. For that purpose, endothelial P-selectin expression was measured by the radiolabeled antibody technique in control and irradiated mice at 2, 6, and 24 hr following abdominal irradiation with 4 or 10 Gy; leukocyte endothelial cell interactions were assessed using intravital microscopy in intestinal venules following irradiation at the aforementioned doses and times in C57BL/6 and P-selectin-deficient mice. In wild-type mice, radiation induced a time- and dose-dependent up-regulation of P-selectin and a significant increase in the flux of rolling leukocytes 2 hr after irradiation. Irradiation induced a significant increase in leukocyte adhesion that was dose-dependent. Following irradiation, P-selectin-deficient mice did not show any increase in leukocyte rolling but did demonstrate a response in leukocyte adhesion similar to that of the wild-type mice. Radiation-induced dose-dependent histological inflammatory damage that did not differ between P-selectin-deficient and wild-type mice. We conclude that P-selectin is up-regulated following irradiation and is a key molecular determinant of leukocyte rolling but not leukocyte adhesion in this inflammatory condition. Therefore, isolated neutralization of this adhesion molecule is not an effective means for preventing radiation-induced inflammation.

Abstract
BACKGROUND AND AIMS Circulating tumor cells in peripheral blood may be detected using high-sensitivity molecular techniques in several types of solid neoplasms, but their significance in colorectal cancer is controversial. The aim of this study was to assess the prognostic value of carcinoembryonic antigen (CEA) messenger RNA (mRNA) detection in peripheral blood samples from patients with colorectal cancer. METHODS Peripheral vein blood samples from 95 consecutive patients with histologically confirmed colorectal carcinoma were obtained immediately before surgery to determine the presence of circulating tumor cells by use of a reverse-transcription polymerase chain reaction targeting CEA mRNA. Endpoints of the study were disease-free and overall survival. Results are referred to the whole series and, more importantly, to the 68 patients who underwent surgery for cure. RESULTS After a median follow-up of 42 months, 19 of 68 patients (28%) operated on for cure had tumor relapse. In addition, 50 of 68 patients (73%) were alive. The probability of disease-free and overall survival was dependent on lymph node metastases and degree of differentiation, but not on the presence of circulating tumor cells (disease-free survival: relative risk, 1.00; 95% confidence interval [CI], 0.39-2.22, P = 0.99; overall survival: relative risk, 0.91, 95% CI, 0.34-2.43; P = 0.84). Similar results were obtained when all 95 patients with colorectal cancer were analyzed (disease-free survival: relative risk, 1.11; 95% CI, 0.63-1.95; P = 0.71; overall survival: relative risk, 1.21; 95% CI, 0.63-2.30, P = 0.55). CONCLUSIONS Preoperative detection of blood circulating tumor cells by means of reverse-transcription polymerase chain reaction of CEA does not have prognostic significance in patients with colorectal cancer.

Abstract
BACKGROUND AND AIMS The role of selectins in experimental colitis remains unknown. The aims of this study were to characterize the time-course expression of selectins in trinitrobenzene sulfonic acid (TNBS)-induced colitis, the functional role of selectins in colonic leukocyte-endothelial cell interactions, and the therapeutic usefulness of selectin blockade in this model. METHODS Control and TNBS-induced colitic rats were studied. Expression of P- and E-selectin was assessed by the radiolabeled antibody technique, and L-selectin by flow cytometry. Leukocyte-endothelial cell interactions were studied in colonic venules by using intravital microscopy under basal conditions and after P-, E-, or L-selectin immunoblockade. Additional groups of animals were treated with anti-P-selectin antibody, a nonbinding antibody, or dexamethasone, for 7 days. RESULTS P-selectin and E-selectin expression were markedly up-regulated in colitic rats. Increased leukocyte rolling was abrogated by anti-P-selectin, but only attenuated by anti-E- or anti-L-selectin antibodies. Only pretreatment with anti-P- selectin decreased leukocyte adhesion. Animals chronically treated with dexamethasone, but not with anti- P-selectin, had significantly lower macroscopic and histologic damage scores, colon weight, and myeloperoxidase (MPO) activity than those treated with nonbinding antibody. CONCLUSIONS P-selectin plays a key role on leukocyte rolling and its blockade attenuates leukocyte adhesion in TNBS-induced colitis. However, treatment with an anti-P-selectin antibody does not significantly improve colitis.

Abstract
Laparoscopic surgery for treatment of colorectal cancer has been suggested to enhance tumor dissemination. Recently, molecular techniques have been developed to detect micrometastatic disease in patients with solid tumors, with a higher accuracy than cytologic or immunohistochemical approaches. This study was undertaken to investigate the potential harmful effects of laparoscopic-assisted colectomy on neoplastic cell mobilization in patients with resectable colorectal cancer. Fifty patients with nonmetastatic colorectal cancer were randomly assigned to laparoscopic-assisted (LAC, n = 26) or open (OC, n = 24) colectomy. Peripheral venous blood samples were obtained preoperatively, immediately after tumor removal, and 24 hours later. In 10 patients from each treatment group, portal blood and peritoneal fluid samples were also obtained before and after resection. Neoplastic cells were detected by means of reverse transcriptase-polymerase chain reaction targeted to carcinoembryonic antigen (CEA) transcription. CEA mRNA was detected in peripheral venous blood samples from 35 of 50 colorectal cancer patients preoperatively. Among those 15 baseline-negative patients, four experienced conversion 24 hours after tumor resection (2 [33%] of 6 in the LAC group vs. 2 [22%] of 9 in the OC group; NS). At that time point, clearance of CEA mRNA expression was observed in 14 of the 35 baseline-positive patients (9 [45%] of 20 in the LAC group vs. 5 [33%] of 15 in the OC group; NS). In addition, only one patient in the LAC group with baseline-negative CEA mRNA expression experienced portal blood conversion after tumor removal, although his peripheral blood level remained negative. Finally, baseline peritoneal fluid CEA mRNA expression was never detected, but one patient in each group became positive postoperatively. These results confirm that preoperative and perioperative mobilization of neoplastic cells is a frequent occurrence in patients with colorectal cancer, but the surgical approach (LAC vs. OC) does not seem to be a determining factor.

Abstract
Previous studies indicate that ischemic preconditioning protects against lung injury resulting from hepatic ischemia-reperfusion (I/R) through inhibition of tumor necrosis factor (TNF) release from Kupffer cells. The present study investigated whether this effect is limited to the lung or is a generalized systemic response and explores the molecular mechanisms involved. Hepatic I/R led to an increase in neutrophil accumulation in liver, lung, and splanchnic organs. Although preconditioning did not modify neutrophil infiltration in liver during reperfusion, it conferred protection against hepatic injury associated with I/R. In remote organs, preconditioning abrogated the increase in P-selectin up-regulation, preventing neutrophil infiltration and thus reducing the oxidative stress and microvascular disorders following hepatic I/R in these organs. Administration of Abs against P-selectin or TNF previous to ischemia had the same effects as preconditioning. The effects of preconditioning on the blockade of P-selectin up-regulation probably results from inhibition of systemic TNF release from Kupffer cells. Supplementation of TNF abolished the benefits of preconditioning, whereas the injurious effects of TNF were prevented by previous blockade of P-selectin. The results of the present study suggest that ischemic preconditioning protects the liver against I/R injury by a mechanism independent of adhesion molecule expression and neutrophil accumulation. In remote organs, however, hepatic preconditioning prevents inflammatory damage by reducing the systemic TNF release from the liver and thus preventing P-selectin up-regulation.

Abstract
OBJECTIVES To evaluate the usefulness of 123I-labelled anti-vascular cell adhesion molecule-1 (VCAM-1) monoclonal antibody (MAb) scintigraphy in the assessment of colonic inflammatory damage. DESIGN Colitis was induced by intracolonic administration of 30 mg trinitrobenzenesulphonic acid in 0.5 ml of 50% (v/v) ethanol. Rats injected with vehicle served as controls. Animals were studied at day 7 after induction of colitis. METHODS Scintigraphy was performed in control and trinitrobenzenesulphonic acid-induced colitic rats 2, 4 and 24 h after intravenous administration of 123I-anti-VCAM-1 MAb. Scintigraphic uptake was quantified in selected areas on scintigraphs. Animals were killed, tissue 123I radioactivity accumulation was measured, and accumulation of anti-VCAM-1 MAb in each organ was calculated. 99mTc-hexamethyl propylene amine oxime-labelled leucocyte scintigraphy was performed in additional groups of animals for comparison. RESULTS Colonic tracer uptake was visible in scans of colitic, but not control animals. Quantification of scintigraphic uptake in the colon was significantly higher in colitic rats than in control animals (P< 0.0001). The specificity of the increase was demonstrated by lack of 123I-labelled non-binding MAb uptake in the colon, and by displacement of 123I-anti-VCAM-1 MAb colonic uptake by pre-treatment with unlabelled MAb. Accumulation of anti-VCAM-1 MAb in the colon of colitic rats was eightfold higher than in control animals. Strong correlations were found between quantification of scintigraphic uptake, anti-VCAM-1 MAb accumulation, histological damage and myeloperoxidase activity in the colon. CONCLUSION 123I-labelled anti-VCAM-1 MAb scintigraphy allows an accurate evaluation of colonic inflammatory damage in trinitrobenzenesulphonic acid-induced colitis, suggesting a potential role for this imaging technique in the assessment of human IBD.

Abstract
OBJECTIVE To prospectively assess the accuracy of a scoring system to predict organic diseases in dyspeptic patients in an area of South Europe, and to compare it with that of Helicobacter pylori testing in patients with dyspepsia in an environment with high prevalence of H. pylori infection. METHODS Symptoms and demographic data were recorded in 501 consecutive dyspeptic patients referred to an outpatient gastroenterology clinic. A simple scoring system was constructed from the predictive factors obtained in a multi-variate logistic regression analysis. Overall predictive accuracy was assessed with the c statistic. The model was validated using bootstrap techniques. The accuracy of clinical judgement and H. pylori testing to predict endoscopic diagnosis was also assessed. RESULTS Organic dyspepsia (peptic ulcer, oesophagitis or malignancies) was diagnosed in 45% of the patients. The test for H. pylori was positive in 68%, and 29% of infected patients had an ulcer. The organic dyspepsia predictive model had an accuracy of 0.79, which decreased to 0.77 after validation adjustment. The predictive accuracies for clinical judgement and H. pylori testing were 0.69 and 0.61, respectively. The addition of H. pylori testing to the scoring system resulted in a minor improvement of the predictive accuracy. CONCLUSION In an environment with a high rate of H. pylori infection and a low prevalence of peptic ulcer among infected patients, a scoring system has higher predictive accuracy for the diagnosis of organic disease than H. pylori testing. Moreover, in this setting, H. pylori testing adds a minimum value to the predictive capability of the scoring system.
