Primary (retractile) mesenteritis in a child

Area of Science:

• Pediatric Surgery
• Gastroenterology
• Abdominal Imaging

Background:

• Primary retractile mesenteritis is a rare condition characterized by inflammation and fibrosis of the small bowel mesentery.
• It can present with non-specific symptoms, often mimicking surgical emergencies like appendicitis or bowel obstruction.
• Early diagnosis and appropriate management are crucial to prevent complications.

Observation:

• A 3-year-old boy presented with acute abdominal pain necessitating surgical intervention.
• Intraoperative findings revealed hemoperitoneum (blood in the abdominal cavity).
• A diagnosis of primary retractile mesenteritis was established using intraoperative frozen section biopsy of the small bowel mesentery.

Findings:

• The diagnosis of primary retractile mesenteritis was confirmed intraoperatively via frozen section biopsy.
• The surgical team opted against intestinal resection due to the nature of the findings.
• The patient experienced an uncomplicated recovery following the surgical exploration.

Implications:

• This case highlights the importance of considering rare diagnoses like primary retractile mesenteritis in pediatric patients with acute abdomen.
• Intraoperative frozen section biopsy can be a valuable tool for rapid diagnosis in challenging surgical cases.
• Conservative management, avoiding resection when possible, may lead to favorable outcomes in primary retractile mesenteritis.
