This cluster of papers focuses on the diagnosis and management of gastrointestinal bleeding, with an emphasis on techniques such as capsule endoscopy and double-balloon enteroscopy. It covers topics such as the diagnostic yield of different modalities, risk scoring for predicting need for treatment, outcomes after endoscopic therapy, and the role of endoscopy in acute upper and lower gastrointestinal bleeding. The cluster also addresses specific conditions like peptic ulcers, obscure gastrointestinal bleeding, and angiodysplasia.
