Intramural duodenal hematoma is a rare condition described for the first time in 1838. This condition is usually associated with blunt abdominal trauma in children. Other non-traumatic risk factors for spontaneous duodenal haematoma include several pancreatic diseases, coagulation disorders, malignancy, collagenosis, peptic ulcers, vasculitis and upper endoscopy procedures. In adults the most common risk factor reported is anticoagulation therapy. The clinical presentation may vary from mild abdominal pain to acute abdomen and intestinal obstruction or gastrointestinal bleeding.
The aim of this case summary is to show a case of intramural spontaneous hematoma with symptoms of intestinal obstruction that was properly drained endoscopically by an innovative system lumen-apposing metal stent Hot AXIOS™ stent (Boston Scientific Corp., Marlborough, MA, United States).
Endoscopic lumen-apposing metal stent Hot AXIOS™ stent is a safe and feasible treatment of duodenal intramural hematoma in our case.
Core Tip: The present case explored the feasibility, safety and efficacy of endoscopic ultrasound-guided drainage of spontaneous duodenal hematoma. The new lumen-apposing self-expandable metallic stent Hot AXIOS™ could be considered a valid alternative to conventional endoscopic incision of the hematoma by using a needle-knife, a biopsy forceps or surgical drainage and percutaneous drainage to relieve pain and a persistent duodenal ulcer.
