Summary

Air in Morison pouch is an early sign of pneumoperitoneum in newborns with necrotizing enterocolitis (NEC). This finding, often missed, indicates the need for immediate surgical intervention.

Area of Science:

  • Pediatric Surgery
  • Neonatal Imaging
  • Gastroenterology

Background:

  • Necrotizing enterocolitis (NEC) is a critical condition in newborns.
  • Pneumoperitoneum is a known complication of NEC, often requiring surgery.
  • Early detection of NEC complications is vital for patient outcomes.

Purpose of the Study:

  • To identify Morison pouch air as an early indicator of pneumoperitoneum in NEC.
  • To highlight the significance of this finding in neonatal surgical emergencies.
  • To increase awareness of this subtle radiographic sign among clinicians.

Main Methods:

  • Retrospective review of six newborn infants diagnosed with NEC.
  • Radiographic analysis focusing on the presence and appearance of air in Morison pouch.
  • Comparison of findings with existing literature on NEC and pneumoperitoneum.

Main Results:

  • Air confined to Morison pouch was observed in six NEC patients as an early sign of pneumoperitoneum.
  • This triangular lucency in the right upper quadrant can be mistaken for bowel gas.
  • Literature review found no prior reports linking Morison pouch air to NEC.

Conclusions:

  • Air in Morison pouch is a potentially common, yet under-recognized, sign of pneumoperitoneum in NEC.
  • Detection of Morison pouch air warrants the same surgical consideration as other pneumoperitoneum signs.
  • Increased radiologist and clinician awareness can improve early diagnosis and management of NEC.
