Core Tip

Core Tip: Balloon enteroscopy is often warranted in patients with surgically altered anatomy who suffer from obscure gastrointestinal (GI) bleeding. Data remain limited on the clinical utility of single or double balloon enteroscopy in those with altered anatomy. The primary aim of this systematic review was to assess the diagnostic and therapeutic efficacy of balloon enteroscopy for obscure GI bleeding in patients with surgically altered anatomy. The secondary aim was to investigate the safety of balloon enteroscopy in this patient population.
