Core Tip

Core Tip: Rare and extraordinary rare causes of non-variceal upper gastrointestinal bleeding (NVUGIB) are commonly life-threatening conditions. Thus, a prompt diagnosis and a subsequent equally early treatment are required, typically involving a patient-tailored, multidisciplinary team approach. However, given the rare occurrence, their management is not covered by NVUGIB current guidelines. Our study aimed to review the current evidence with regard to the management of rare and extraordinary rare causes of NVUGIB.
