Delayed duodenal obstruction after intramural hematoma in a patient with paroxysmal nocturnal hemoglobinuria: A case report

INTRODUCTION: Paroxysmal nocturnal hemoglobinuria (PNH) is a clonal stem cell disorder of hematopoietic cells. Gastrointestinal complications of PNH are rare and mostly related with intravascular thrombosis or intramural hematoma. PRESENTATION OF CASE: We describe a case of a man with PNH complicated by intramural duodenal hematoma initially treated with supportive care. Three months after his first admission; he was admitted to the emergency department with abdominal pain, nausea and vomiting. He had undergone to surgery because of duodenal obstruction was treated with duodenojejunal by-pass surgery. DISCUSSION: Patients were healed from gastrointestinal complications could suffer from gastrointestinal strictures, which cause wide spread symptoms ranging from chronic abdominal pain and anorexia to intestinal obstruction. CONCLUSION: We report a rare intestinal obstruction case caused by stricture at the level of ligamentum Treitz with PNH. The possibility simply has to be borne in mind that strictures can be occurring at hematoma, ischemia or inflammation site of gastrointestinal tract.
