Haemosuccus pancreaticus and seven episodes of recurrent unlocalised upper gastrointestinal bleeding.

ABSTRACT

Upper gastrointestinal (GI) bleeding is a common medical condition that results in extensive morbidity and mortality, as well as substantial healthcare costs. While there is variation among society and consensus guidelines, the approaches to assessment and evaluation are generally consistent. Our case describes a man in his 40s who presented with seven episodes of recurrent upper GI bleeding over 2 years secondary to haemosuccus pancreaticus. While rare, this case study highlights key principles to the initial diagnostic approach that, in appropriate clinical contexts, should be applied to patients with unlocalised upper GI bleeding. We further perform a complete systematic review of similar cases available in PubMed (36 patients in 24 case reports) to further refine these diagnostic principles.
