screened. As might be expected from an older population a higher cancer detection rate was observed, although a higher drop-out rate was also seen, even in those fit to proceed to a diagnostic test.If participation in over 75's continues to increase, particularly following the introduction of the new (more sensitive and easier to use) faecal immunochemical test in June 2019, it is likely to impact further on the already stretched colonoscopy services in England.

Purpose of reviewThe diagnosis of small bowel lymphoma (SBL) can be challenging, as they are very rare and also have a varied presentation. In this review, we aim to provide a broad overview of the types of SBL and also about the various modalities used for their diagnosis. We also discuss the overview of treatment strategies for a gastroenterologist.Recent findingsSmall bowel capsule endoscopy (SBCE) and devise-assisted enteroscopy (DAE) has revolutionized the way we investigate the small bowel. DAE also makes it possible to obtain histological samples for further characterization of SBL. This has led to a significant improvement in diagnosis and management of the disease in conjunction with cross-sectional imagining.SummaryThe diagnosis and management of small bowel lymphoma remains challenging despite the development of newer techniques such as SBCE and DAE. The current available diagnostic modalities have limitations; in the absence of a gold standard, the current investigative modalities compliment each other in reaching the final diagnosis.
