Background and aims SARS-CoV-2 and consequent pandemic has presented unique challenges. Beyond the direct COVID-related mortality in those with liver disease, we sought to determine the effect of lockdown on people with liver disease in Scotland. The effect of lockdown on those with alcohol-related disease is of interest; and whether there were associated implications for a change in alcohol intake and consequent presentations with decompensated disease. Methods We performed a retrospective analysis of patients admitted to seven Scottish hospitals with a history of liver disease between 1 April and 30 April 2020 and compared across the same time in 2017, 2018 and 2019. We also repeated an intermediate assessment based on a single centre to examine for delayed effects between 1 April and 31 July 2020. Results We found that results and outcomes for patients admitted in 2020 were similar to those in previous years in terms of morbidity, mortality, and length of stay. In the Scotland-wide cohort: admission MELD (Model for End-stage Liver Disease) (16 (12–22) vs 15 (12–19); p=0.141), inpatient mortality ((10.9% vs 8.6%); p=0.499) and length of stay (8 days (4–15) vs 7 days (4–13); p=0.140). In the Edinburgh cohort: admission MELD (17 (12–23) vs 17 (13–21); p=0.805), inpatient mortality ((13.7% vs 10.1%; p=0.373) and length of stay (7 days (4–14) vs 7 days (3.5–14); p=0.525)). Conclusion This assessment of immediate and medium-term lockdown impacts on those with chronic liver disease suggested a minimal effect on the presentation of decompensated liver disease to secondary care.

Background: Once clinically stable, patients with coeliac disease should have annual follow-up. Lack of capacity in gastroenterology outpatient clinics mean alternatives are required. Objectives: We studied the effectiveness of follow-up deferred to general practitioners (GP-FU) and compared this with a neighbouring Trust where follow-up was through a dedicated nurse-led telephone clinic (T-FU). Design: All patients with coeliac disease were posted a questionnaire examining patient satisfaction, adherence with gluten-free diet and calcium intake. Results: 517 of 825 patients (62.7%) completed a postal questionnaire (median age 61, 72% female). 28% of GP-FU and 84% of T-FU patients received an annual review. Of those seen, 33% (GP-FU) and 53% (T-FU) were weighed (χ² 65.8, p2 81.1, p2 60.6, p2 88.2, p2 17.6, p<0.001). Conclusions: Discharge of patients with coeliac disease to primary-care in many cases results in their complete loss to follow-up. When patients were reviewed, either by GP-FU and T-FU, many aspects of their care are not addressed. Whether this will result in late complications remains to be seen.

Objective: There are little data on the prevalence of reduced bone mineral density (BMD) in young adult patients with coeliac disease; guidelines do not support routine investigation of these patients. We assessed the prevalence of reduced BMD in our patients by age. Patients and methods: Prospective observational study of 260 coeliac patients having DXA one year after commencing gluten-free diet. Nonparametric tests and regression were used. Results: Median age was 51years, BMI 24 and 85 (32.7%) were male. Reduced BMD was associated with increasing age (p < .001), female sex (p = .005), low BMI (p < .001) and previous fracture (p < .01); 49% of all patients and all patients under 20 years old had reduced BMD. The median age of patients with BMI 2 was 56 (27, 70) years with the majority of younger patients having normal BMI. Conclusions: Low BMD is a common finding in young patients with coeliac disease, yet routine assessment of BMD is not currently supported by national guidelines. Early identification may improve motivation to comply with GFD and allow adequate calcium and vitamin D supplementation to reduce risk of fracture later in life.

Objectives: Dysphagia is a presenting symptom of both pharyngeal and oesophageal cancers. The referral pathway choice is determined by whether it is thought to be oropharyngeal or oesophageal, and this is in turn influenced by whether dysphagia is perceived to be above or below the suprasternal notch. We studied the concordance between the presence of pharynx‐localised dysphagia (PLD) and the location of the underlying disease processes.Design: A subset analysis of the Dysphagia Hotline Cohort, collected between 2004 and 2015, of patients with PLD and a structural diagnosis.Main outcome measures: Information about patient demography and presenting symptoms were recorded. The incisor‐to‐pathology distance, and the nature of the pathology, were recorded. Logistic regression analysis was used to identify independent predictors of malignancy.Results: The study included 177 patients. There were 92 males, and mean age at presentation was 74 years. The commonest benign pathologies were cricopharyngeal dysfunction with or without pharyngeal pouch (n = 67), peptic stricture (n = 44) and Schatzki's ring (n = 11). There were 49 cases of cancer, including one hypopharyngeal cancer, one cervical oesophageal cancer, 28 cancers of the upper/mid‐thoracic oesophagus, 15 cancers of the lower thoracic oesophagus and 4 cardio‐oesophageal cancers. In 105 (59%) patients, PLD was caused by oesophageal disease. Independent predictors of malignancy were weight‐change (loss >2.7 kg), a short history (<12 weeks) and presence of odynophagia. Nineteen (39%) of oesophageal cancers that presented with dysphagia that was localised only to the pharynx would have been beyond the reach of rigid oesophagoscopy.Conclusions: Pharynx‐localised dysphagia is more likely to be a referred symptom of structural oesophageal disease, including cancer, than a primary symptom of structural pharyngeal disease. Absence of additional alarm symptoms such as a short history, weight‐loss, and odynophagia, do not adequately exclude the possibility of oesophageal cancer. When the differential diagnosis of PLD includes malignancy, cancer should be presumed to be arising from the oesophagus or the cardio‐oesophageal region until proven otherwise. This requires direct visualisation of the mucosal surfaces of the oesophagus and the cardio‐oesophageal region, using either transoral or transnasal flexible endoscopy, irrespective of whether the initial assessment occurs within head and neck or upper gastrointestinal suspected cancer pathways.

Introduction: Out of hours admissions have higher mortality for many conditions but upper gastrointestinal haemorrhage studies have produced variable outcomes.Methods: Prospective study of 12 months consecutive admissions of upper gastrointestinal haemorrhage from four international high volume centres. Admission period (weekdays, weeknights or weekends), demographics, haemodynamic parameters, laboratory results, endoscopy findings, further procedures and 30‐day mortality were recorded. Five upper gastrointestinal haemorrhage risk scores were calculated.Results: 2118 patients, 60% male, median age 66 years were studied. Compared with patients presenting on weekdays, patients presenting at weekends had no significant differences in comorbidity, pulse, systolic BP, risk scores, frequency of peptic ulcers or varices. Those presenting on weekdays had lower haemoglobin (p = 0.007) and were more likely to have a normal endoscopy (p < 0.01). Time to endoscopy was less for weeknight presentation (p = 0.001). Sixty‐seven per cent of those presenting on weekdays, 75% on weeknights and 60% at weekends had endoscopy within 24 h. Transfusion requirements, need for endoscopic therapy or surgery/embolization, rebleeding rates (6.1%) and mortality (7.2%) did not differ with presentation time.Conclusion: This multi‐centre international study in large centres found no difference in demographics, comorbidity or haemodynamic stability and no increase in mortality for patients presenting with upper gastrointestinal haemorrhage out of hours.

Aims: To determine the value of ⁷⁵SeHCAT retention in determining bile acid diarrhoea (BAD), treatment response and predictors of a positive result. Methods: Retrospective casenote review of consecutive patients undergoing ⁷⁵SeHCAT from 2008 to 2014, including gender, age, history, clinical, and laboratory parameters. This included diseases associated with Type 1 BAD (ileal resection, Crohn’s disease) and Type 3 BAD. Chi-squared test and logistic regression determined factors predictive of BAD. Subjective response to treatment with bile acid sequestrants (BAS) was analysed with respect to the ⁷⁵SeHCAT result. Results: Of 387 patients, 154 (39.7%) were male and average age was 50 years. Ninety-five patients (24.5%) were investigated for Type 1 BAD, 86 (22.2%) for Type 3, and 206 patients (53.2%) for Type 2 or idiopathic BAD. There was a large increase in the number performed with time but no difference in percentage positive tests. One hundred and seventy-nine patients (46.2%) had BAD. Positive result was commonest in possible Type 1 and they had most severe BAD. Ninety-nine patients had severe BAD (75SeHCAT retention), 47 moderate BAD (5% to 75SeHCAT were right hemicolectomy (OR 4.88), cholecystectomy (OR 2.44), and Crohn’s (OR 1.86). A positive ⁷⁵SeHCAT predicted a good or partial response to BAS of 66.7% (mild), 78.6% (moderate), or 75.9% (severe BAD). Conclusion: ⁷⁵SeHCAT test use increased in 2008–2014, with high positive results throughout. Ileal resection, Crohn’s, and cholecystectomy independently predict BAD. ⁷⁵SeHCAT predicted response to BAS.

Objective To compare the predictive accuracy and clinical utility of five risk scoring systems in the assessment of patients with upper gastrointestinal bleeding. Design International multicentre prospective study. Setting Six large hospitals in Europe, North America, Asia, and Oceania. Participants 3012 consecutive patients presenting over 12 months with upper gastrointestinal bleeding. Main outcome measures Comparison of pre-endoscopy scores (admission Rockall, AIMS65, and Glasgow Blatchford) and post-endoscopy scores (full Rockall and PNED) for their ability to predict predefined clinical endpoints: a composite endpoint (transfusion, endoscopic treatment, interventional radiology, surgery, or 30 day mortality), endoscopic treatment, 30 day mortality, rebleeding, and length of hospital stay. Optimum score thresholds to identify low risk and high risk patients were determined. Results The Glasgow Blatchford score was best (area under the receiver operating characteristic curve (AUROC) 0.86) at predicting intervention or death compared with the full Rockall score (0.70), PNED score (0.69), admission Rockall score (0.66, and AIMS65 score (0.68) (all PConclusions The Glasgow Blatchford score has high accuracy at predicting need for hospital based intervention or death. Scores of ≤1 appear the optimum threshold for directing patients to outpatient management. AUROCs of scores for the other endpoints are less than 0.80, therefore their clinical utility for these outcomes seems to be limited. Trial registration Current Controlled Trials ISRCTN16235737.
