When the physician suspects that there is a lesion which cannot be seen in an upper endoscopy or colonoscopy, or when there are blood clots, or when the patient prepared poorly for the procedure, studies should be repeated. This is especially true when hematemesis are found or there is a history of NSAIDs.
En caso de sospecha de lesión no visualizada en endoscopia alta y colonoscopia, ante la presencia de coágulos o de mala preparación, estos estudios deben ser repetidos, sobre todo cuando se encuentra hematemesis o antecedente de consumo de AINE.
