Aim: The aim of this work was to quantify post-colonoscopy colorectal cancer (PCCRC) rates in National Health Service (NHS) Scotland using World Endoscopy Association guidelines, compare incidence between health boards and referral streams and explore comparisons in results with published data from other healthcare systems.
Method: This is a population-based cohort study using NHS Scotland data between 2012 and 2018. All people undergoing colonoscopy between 2012 and 2018 and subsequently diagnosed as having bowel cancer up to 3 years after their investigation were included.
Background: The faecal immunochemical test (FIT) has proven utility for colorectal cancer detection in symptomatic patients. However, most patients with a raised faecal haemoglobin (f-Hb) do not have colorectal cancer. We investigated alternative diagnoses and demographics associated with a raised f-Hb in symptomatic patients.

Most studies have examined FIT in symptomatic patients subsequently referred from primary care. We investigated associations between CRC and FIT in both referred and non-referred symptomatic patients.

We investigated whether mercaptopurine can prevent or delay postoperative clinical recurrence of Crohn's disease.
Methods: We did a randomised, placebo-controlled, double-blind trial at 29 UK secondary and tertiary hospitals of patients (aged >16 years in Scotland or >18 years in England and Wales) who had a confirmed diagnosis of Crohn's disease and had undergone intestinal resection.
Background: Faecal calprotectin (FC) is a non-invasive marker of gastrointestinal inflammation.
Aim: To determine whether higher FC levels in individuals with quiescent Crohn's disease are associated with clinical relapse over the ensuing 12 months.
Methods: A single centre prospective study was undertaken in Crohn's disease patients in clinical remission.

Purpose Of Review: To analyse the concept of nonerosive reflux disease (NERD), examining its evolving definition and its relationship to reflux disease and functional gastrointestinal disorders.
Recent Findings: The advent of the Montreal definition of gastroesophageal reflux disease (GERD) and the Rome III definition of functional upper gastrointestinal disorders has refined the concept of NERD. The high prevalence of GERD symptoms and the strong overlap between GERD and irritable bowel syndrome is due to the influence of NERD.
Background & Aims: Nitrate ingestion leads to high luminal concentrations of nitric oxide being generated where saliva meets gastric acid. Nitric oxide generates N-nitrosative stress on reacting with oxygen at neutral pH. We aimed to ascertain if luminal nitric oxide exerts nitrosative stress in the human upper gastrointestinal tract, and to assess the influence of acid reflux on this phenomenon.
