Prognostic factors and concomitant anomalies in neonatal gastric perforation

Neonatal gastric perforation is a rare and serious issue. This study aimed to highlight the vital clinical features and identify prognostic factors in such cases.

Medical charts from January 1997 through December 2008 were reviewed retrospectively. Neonates with a diagnosis of gastric perforation were included.

Thirteen patients were identified with a male:female ratio of 9:4. Five (38%) were preterm infants. The mortality rate was 30% (4/13), and the median age of onset was 3 days (range: 1-14 days). The most common presenting sign was abdominal distension, followed by respiratory distress and vomiting. Except for one patient in whom gastric perforation was diagnosed during surgical repair for gastroschisis, all patients had pneumoperitoneum on admission; 70% and 46% of patients had peritonitis and sepsis, respectively. Concomitant gastrointestinal (GI) tract anomalies or disorders included ischemic bowel/necrotizing enterocolitis (5 patients), intestinal malrotation (2), duodenal web (1), hiatal hernia (1), and gastroschisis (1), which necessitated secondary operations during hospitalization in 5 patients. Seven patients had leukopenia on admission, and 9 developed thrombocytopenia in the following 48 h. All patients who died presented with leukopenia on admission and thrombocytopenia in the following 48 h, yielding sensitivity and specificity rates of 100% and 67%, respectively.

Neonatal gastric perforation is often concomitant with GI anomalies or inflammatory/infectious disease. Patients who were outborn and those with leucopenia, peritonitis, and thrombocytopenia development within 48 h were at risk for poor outcome.
