Abstract Background The COVID-19 pandemic profoundly affected endoscopy services including therapeutic gastroscopy across the UK. The BSG (British Society of Gastroenterology) issued guidance for managing endoscopy services safely throughout this period. At the beginning of the pandemic in March 2020, a symptom-based questionnaire was used to screen patients for COVID-19 prior to their endoscopic procedures in our hospital (COVID-19 swabs were only carried out if patients presented with COVID-19 symptoms). From 18 May 2020 onwards, in addition to the above approach, all patients attending endoscopic procedures underwent a SARS-CoV-2 nasopharyngeal swab 1-3 days prior to the procedure. We describe our experience of UGI stenting and dilatation during the initial wave of COVID-19 pandemic in the UK.  Aims To assess the impact of COVID-19 pandemic on technical and clinical success of luminal dilatation and stenting in the UGI tract and ascertain the risk of procedure related complications. Methods A retrospective audit of a prospectively maintained endoscopy database was carried out between 18th March and 31st July. All patients were followed for 30 days. Full PPE were used. Results 42 procedures [31 were oesophageal dilatation (21 peptic stricture, 9 radiotherapy stricture, 1 achalasia), 8 oesophageal stent insertion (6 for primary oesophageal cancer, 1 metastatic cancer and 1 secondary to external compression from lung cancer) and 3 pyloric dilatation all benign] were carried out-mean age 65 years, 64.3% males, 81% of procedures were carried out as outpatients. All procedures were performed under fluoroscopy. 41/42(97.6%) patients had a confirmed histology prior to their procedure – one patient who underwent oesophageal dilatation had a peptic stricture on endoscopy (no biopsy or imaging). 39/42(92.9%) patients had undergone CT scan and/or barium swallow prior to their first procedure. All procedures were technically and clinically successful (100%).There were no procedure related complications or mortality. There were no COVID positive swabs in the 30-day post procedure period during the entire study period. Trainees were present in 21/42 (50%) of the procedures. None of the endoscopists who were involved with these procedures were diagnosed with COVID-19 during this period. One of the nursing staff, who regularly assisted in the fluoroscopy room, was involved in a non-fluoroscopic endoscopic procedure in a COVID-19 patient (not known at the time of the procedure) and subsequently tested positive.  Conclusions Our study confirms that a high quality stenting and dilatation service of the upper gastrointestinal tract together with specialist registrar training can be delivered safely and effectively during the COVID-19 pandemic in appropriately prioritised symptomatic patients.

Chapter 7 discusses the upper gastrointestinal tract, and addresses the technical challenges of these cancersin relation to tumour volumes, anatomical situation, and poor normal tissue tolerance, particularly of the intra-abdominal contents. More contemporaneous treatment techniques such as intensity-modulated radiotherapy and stereotactic ablative radiotherapy have not currently made significant impact in the routine treatment of upper gastrointestinal tumours in the UK.

Background and objectives: Although treatment with novel oral non-vitamin K antagonist 3anticoagulants (NOACs) is associated with an overall decrease in hemorrhagic complications compared to warfarin, the incidence of gastrointestinal bleeding remains contradictory. Materials and Methods: After the exclusion of patients with pre-existing pathological lesions in the upper gastrointestinal tract (GIT) on esophageal-gastroduodenoscopy (EGD) at entry, a cohort of 80 patients (mean age of 74.8 ± 2.0 years) was randomly divided into four equivalent groups, treated with dabigatran, rivaroxaban, apixaban, or warfarin. Patients were prospectively followed up for three months of treatment, with a focus on anamnestic and endoscopic signs of bleeding. In addition, bleeding risk factors were evaluated. Results: In none of the patients treated with warfarin or NOACs was any serious or clinically significant bleeding recorded within the follow-up period. The incidence of clinical bleeding and endoscopically detected bleeding in the upper GT after three months of treatment was not statistically different among groups (χ2 = 2.8458; p = 0.41608). The presence of Helicobacter pylori (HP) was a risk factor for upper GIT bleeding (p < 0.05), while the use of proton pump inhibitors (PPIs) was a protective factor (p = 0.206; Spearman’s correlation coefficient = 0.205). We did not record any post-biopsy continued bleeding. Conclusions: No significant GIT bleeding was found in any of the treatment groups, so we consider it beneficial to perform routine EGD before the initiation of any anticoagulant therapy in patients with an increased risk of upper GIT bleeding. Detection and eradication of HP as well as preventive PPI treatment may mitigate the occurrence of endoscopic bleeding. Endoscopic biopsy during the NOAC treatment is safe.

Commercial literature on various probiotic products suggests that they can be taken before meals, during meals or after meals or even without meals. This has led to serious confusion for the industry and the consumer. The objective of our study was to examine the impact of the time of administration with respect to mealtime and the impact of the buffering capacity of the food on the survival of probiotic microbes during gastrointestinal transit. We used an in vitro Digestive System (IViDiS) model of the upper gastrointestinal tract to examine the survival of a commercial multi-strain probiotic, ProtecFlor®. This product, in a capsule form, contains four different microbes: two lactobacilli (Lactobacillus helveticus R0052 and Lactobacillus rhamnosus R0011), Bifidobacterium longum R0175 and Saccharomyces cerevisiae boulardii. Enumeration during and after transit of the stomach and duodenal models showed that survival of all the bacteria in the product was best when given with a meal or 30 minutes before a meal (cooked oatmeal with milk). Probiotics given 30 minutes after the meal did not survive in high numbers. Survival in milk with 1% milk fat and oatmeal-milk gruel were significantly better than apple juice or spring water. S. boulardii was not affected by time of meal or the buffering capacity of the meal. The protein content of the meal was probably not as important for the survival of the bacteria as the fat content. We conclude that ideally, non-enteric coated bacterial probiotic products should be taken with or just prior to a meal containing some fats.

Abstract Aim The aim of our study was to determine the frequency of patients with “true foreign bodies” in the upper gastrointestinal tract and to evaluate the success of urgent endoscopic procedures in removing these objects. Materials and methods The retrospective study includes patients in which urgent endoscopic investigations of the upper digestive tract were performed in a 23-year period, from 1st January 1994 to 1st January 2018. Results Altogether 13 196 patients were investigated: 5147 (39 %) females and 8049 (61 %) males, mean age 62.8 years, SD ± 18.5 years, range 1–106 years. In only 172 patients – 1.3 % of all subjects – true foreign bodies were detected (in range from 1–8) in the esophagus or stomach. In these patients, a total of 242 endoscopic procedures were performed. In 95.9 % the foreign bodies were removed endoscopically (165/172 patients); in 7 cases (4.1 %) the endoscopic procedures were not successful. Among the foreign bodies removed were various metal or plastic objects: hooks, batteries, coins, keys, screws, razor blades, lighters, buttons, toys, 3 toothbrushes as well as impacted safety pins. In patients with successful endoscopic removal, no significant complications were noted. In 12 patients (12/165, 7.2 %), hemorrhages from the region of the esophagogastric junction or stomach were observed; endoscopic hemostasis was performed in 10/12 patients. Conclusions Urgent endoscopy has proved successful in removing true foreign bodies from the upper gastrointestinal tract in the analyzed period. Different factors affect the success of urgent intervention, the most important being adequate experience, skills, and patience of the endoscopic team.

Chapter 6 discusses the upper gastrointestinal tract, and addresses that the technical challenges of these diseases are considerable related to tumour volumes, anatomical situation, and poor normal tissue tolerance particularly of the intra-abdominal contents. More contemporaneous treatment techniques such as IMRT and IGRT have not currently made significant impact in the routine treatment of upper gastrointestinal tumours in the UK.
