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.
