RESUMO
Upper gastrointestinal (GI) bleeds are a common presentation to emergency departments in the UK. The Glasgow Blatchford score (GBS) predicts the outcome of patients at presentation. Current UK and European guidelines recommend outpatient management for a GBS of 0. In the current study, our aim was to assess whether extending the GBS allows for early discharge while maintaining patient safety. We also analysed whether pathologies could be missed by discharging patients too early. Data were retrospectively collected on patients admitted with symptoms of an upper GI bleed between 1 October 2013 and 10 June 2016. The GBS was calculated and gastroscopy reports were obtained for each patient. In total, 399 patients were identified, 63 of whom required therapy. The negative predictive value (NPV) for excluding the need for endoscopic intervention with a GBS score up to 1 was 100%. Extending the score to 2 and 3 reduced the NPV to 98.53% and 98.77%, respectively. The NPV of GBS in excluding any diagnosis at 0 was 43.55%. Two patients died as a result of GI bleeding, with a GBS score of 3. Therefore, we can conclude that, for non-variceal bleeds, the GBS can be extended to 2 for safe outpatient management, thereby reducing the number of bed days and pressure for urgent endoscopies.

OBJECTIVES: Ulcerative colitis (UC) is associated with an increased risk of colorectal cancer (CRC). Few studies have looked at long-term outcomes of endoscopically visible adenomatous lesions removed by endoscopic resection in these patients. We aimed to assess the risk of developing CRC in UC patients with adenomatous lesions that develop within the segment of colitis compared to the remainder of an ulcerative colitis cohort. METHODS: We identified patients with a confirmed histological diagnosis of UC from 1991 to 2004 and noted outcomes till June 2011. The Kaplan-Meier method was used to estimate cumulative probability of subsequent CRC. Factors associated with risk of CRC were assessed in a Cox proportional hazards model. RESULTS: Twenty-nine of 301 patients with UC had adenomatous lesions noted within the segment of colitis. The crude incidence rate of developing colon cancer in patients with UC was 2.45 (95 % CI 1.06-4.83) per 1000 PYD and in those with UC and polypoid adenomas within the extent of inflammation was 11.07 (95 % CI 3.59-25.83) per 1000 PYD. Adjusted hazards ratio of developing CRC on follow-up in UC patients with polypoid dysplastic adenomatous lesions within the extent of inflammation was 4.0 (95 % CI 1.3-12.4). CONCLUSIONS: The risk of developing CRC is significantly higher in UC patients with polypoid adenomatous lesions, within the extent of inflammation, despite endoscopic resection. Patients and physicians should take the increased risk into consideration during follow-up of these patients.

OBJECTIVE: To determine the best faecal calprotectin (FCP) cut-off level for differentiating between irritable bowel syndrome (IBS) and organic disease, particularly inflammatory bowel disease (IBD), in patients presenting with chronic diarrhoea. DESIGN: Retrospective analysis of patients who had colonoscopy, histology and FCP completed within 2â months. SETTING: District general hospital. PATIENTS: Consecutive new patients with chronic diarrhoea lasting longer than 4â weeks. INTERVENTIONS: Patients were seen by a single experienced gastroenterologist and listed for colonoscopy with histology. Laboratory investigations included a single faecal specimen for calprotectin assay (lower limit of detection: 8â µg/g), the results used for information only. MAIN OUTCOME MEASURES: Six FCP cut-off levels (range 8-150â µg/g) were compared against the 'gold standard' of histology: inflammation 'present' or 'absent'. RESULTS: Of 119 patients studied, 98 had normal colonoscopy and histology. The sensitivity of FCP to detect IBD at cut-off levels 8, 25 and 50â µg/g was 100% (with corresponding specificity 51%, 51%, 60%). In contrast, the lowest FCP cut-off, 8â µg/g, had 100% sensitivity to detect colonic inflammation, irrespective of cause (with negative predictive value (NPV) 100%). Importantly, 50/119 patients (42%) with FCP <8â µg/g had normal colonoscopy and histology. CONCLUSIONS: Our results suggest that using FCP to screen patients newly referred for chronic diarrhoea could exclude all without IBD and, at a lower cut-off, all without colonic inflammation, thus avoiding the need for colonoscopy. Such a major reduction has implications for resource allocation.
