A Rare Anatomical Location of Necrotizing Enterocolitis; Neonatal Appendicitis

Öz

Necrotizing enterocolitis(NEC) is the most significant gastrointestinal emergency in neonates, particularly affecting those who are premature. Neonatal appendicitis is highly uncommon in term infants and its diagnosis is typically incidental. The clinical presentation of newborn appendicitis is nonspecific and usually mimics that of NEC. Pneumatosis intestinalis is a finding that is extremely specific to NEC; it is very surprising to observe this finding in a patient with acute appendicitis. A 2730-g male infant was born at 39 weeks gestation to a 33-year-old mother. 30 minutes after delivery , the patient exhibited grunting and respiratory distress and was subsequently admitted to the Neonatal Intensive Care Unit. On the 7th day, the patient developed nutrition intolerance. The feeding was discontinued and the nasogastric catheter was switched to free drainage. Abdominal examination and laboratory parameters were not significant, but direct abdominal radiographs showed findings suggesting pneumatosis intestinalis. NEC was considered and the antibiotics were revised accordingly. The department of pediatric surgery was consulted as the patient’s abdominal examination and radiographs showed abnormalities suggestive of advanced NEC. The patient was taken into operation, gangrenous appendicitis was detected and an appendectomy was performed. When considering the differential diagnosis of NEC in neonatal patients, especially in term infants, clinicians should be mindful of acute appendicitis. In this study, we present a case of neonatal appendicitis, which is relatively common in pediatric cases but uncommon in the neonatal period, presenting as atypical NEC.
