duodenal hematoma
Accumulation of blood within the duodenal wall, often resulting from blunt abdominal trauma.
Full Definition
Duodenal hematoma refers to the accumulation of blood within the layers of the duodenal wall, most commonly occurring as a result of blunt abdominal trauma in children. The duodenum's retroperitoneal location and proximity to the spine make it susceptible to crush injuries from seatbelt compression or bicycle handlebar impacts. The hematoma typically develops in the submucosa or subserosa, causing luminal narrowing and potential obstruction. Children may present with abdominal pain, vomiting, and signs of upper gastrointestinal obstruction. Most duodenal hematomas are managed conservatively with nasogastric decompression and nutritional support, as they typically resolve spontaneously over several weeks.
Usage
Usage note: Specify intramural vs. retroperitoneal location when documenting; distinguish from perforation.
