[A rare cause of postoperative digestive hemorrhage]

Despite all the diagnosis's technical progress achieved in the past years, there are possible haemorrhagic complications after abdominal surgery, creating problems of diagnosis and treatment. The author presents a rare case of postoperative gastrointestinal bleeding due to an ulcer of the jejunal mucosa, located quite close to a hepaticojejunostomy. The mucosal ulcer, with consequent severe, massive bleeding was caused by the migration of a thread from the hepaticojejunostomy, proved by histopathological examination.
