Neonatal Gastric Perforation: Case Series and Literature Review

We reported clinical findings of neonatal gastric perforation in a tertiary children's hospital.

Retrospective chart reviews were conducted for neonatal gastric perforation between 1980 and 2016. Factors including sex, gestational age, birth weight, age, main symptoms and signs, white blood cell count (WBC), surgical intervention time (time between development of main symptom and surgical intervention), surgical findings, pathologic results, clinical outcomes, and causes of death were collected.

Sixty-eight patients were identified. In total, 76.5% were male infants, the median age was 4 days, median birth weight was 2500 g, and 42.6% were premature. Abdominal distention and vomiting were the most common symptoms, and pneumoperitoneum was the most common radiographic finding. The median surgical intervention time was 51 h (range 8-312). In total, 73.5% of perforations occurred in the great curvature, 17.6% in the lesser curvature, and 8.9% unspecified. The median perforation size was 4 cm (range 0.2-16). Associated gastrointestinal anomalies were found in 20.6% of patients, and the most common anomaly was intestinal malrotation. Of the 51 patients with pathologic results, 11 showed the presence of musculature in the perforated gastric wall, while 40 showed the absence of musculature. Of the 66 patients with known clinical outcomes, 26 (39.4%) died, 23 of who died of infection. Among those aforementioned factors, WBC has a significant impact on survival. The mortality for four arbitrary divided year groups (1980-1989, 1990-1999, 2000-2009, and 2010-2016) was 100, 50, 31.6, and 16.7%, respectively.

The mortality of neonatal gastric perforation is constantly decreasing. Associated gastrointestinal anomalies and the presence of musculature are found in a minority of this condition.
