Insights
Internal hernias, though rare in children, can cause acute abdomen after blunt trauma. Prompt diagnosis and surgical repair are crucial to prevent bowel strangulation and ischemia, as shown in a transomental hernia case.
Area of Science:
- Pediatric Surgery
- Abdominal Imaging
- Trauma Surgery
Background:
- Internal hernias are uncommon in pediatric patients.
- Blunt abdominal trauma can precipitate internal hernias.
- Prompt recognition is vital due to high risk of bowel strangulation and ischemia.
Purpose of the Study:
- To highlight the importance of considering internal hernias in pediatric patients with acute abdomen post-trauma.
- To report a case of transomental hernia (TOH) in a young girl following blunt trauma.
- To emphasize the diagnostic and therapeutic approach for internal hernias.
Main Methods:
- Case report of a young female patient presenting with acute abdominal pain 3 weeks after a motor vehicle accident.
- Computed tomography (CT) scan to evaluate for small bowel obstruction and ischemia.
- Urgent surgical intervention and laparoscopic reduction of the transomental hernia.
Main Results:
- CT scan revealed a closed-loop small bowel obstruction with ischemic features, suggestive of internal hernia.
- Surgical exploration confirmed a transomental hernia containing ischemic but viable small bowel.
- Laparoscopic reduction of the TOH was successfully performed.
Conclusions:
- Transomental hernias can occur following blunt abdominal trauma in children.
- CT imaging is crucial for diagnosing internal hernias presenting as small bowel obstruction.
- Laparoscopic surgery offers a successful treatment option for transomental hernias in pediatric patients.
Abstract:
While internal hernias are rare in the paediatric population, it should be considered as a cause for an acute abdomen following blunt trauma. Internal hernias represent a surgical emergency that requires prompt recognition due to the high risk of strangulation and ischaemia of affected bowel loops. The case of a transomental hernia (TOH) is described in a young girl. She re-presented to the emergency department with acute abdominal pain 3 weeks following a motor vehicle accident where she was a restrained passenger. A computed tomography scan demonstrated a closed loop small bowel obstruction with features of ischaemia, which was likely secondary to an internal hernia. Urgent surgical intervention revealed a TOH containing ischaemic but viable loops of small bowel. Laparoscopic reduction of the hernia was successful, and the patient made a good recovery.
