We present the case of a 20-year-old male with no previous history of interest who developed an intraduodenal and retroperitoneal hematoma in the context of an oral endoscopy with duodenal biopsies due to abdominal pain and chronic diarrhea. The evolution with conservative treatment was favorable and ultrasound controls were performed until resolution. Intraduodenal hematomas are lesions that are usually observed in children after blunt abdominal trauma or in patients with risk factors, being infrequent as a complication after diagnostic or therapeutic endoscopic procedures. Their management is mainly conservative and in case of absence of improvement or perforation, surgery is indicated.
Keywords: intraduodenal hematoma, retroperitoneal hematoma, duodenal biopsies.
