Necrotising enterocolitis
Brice Antao, S Irish Michael, Anthony Lander, S Rothenberg MD Steven in Succeeding in Paediatric Surgery Examinations, 2017
Pneumatosis intestinalis (PI) is the cornerstone for the radiographic diagnosis of NEC. In a patient with a suggestive clinical presentation, the presence of PI confirms the diagnosis of NEC, but the absence of PI does not exclude NEC. The pathogenesis of PI is related to the breakdown of mucosal integrity with air dissecting the bowel layers. Subserosal gas usually has a linear appearance whereas submucosal gas has more of a bubbly appearance and, when extensive, can be difficult to differentiate from stool. The presence of diffuse pneumatosis intestinalis and/or portal venous gas on abdominal X-rays is associated with significant NEC. Persistent thrombocytopenia and metabolic acidosis are also part of Bell’s criteria (seeTable 40.1) and raise the suspicion for bowel perforation.

The hallmark of the diagnosis is the finding of pneumatosis intestinalis on plain abdominal x-ray. Free air (pneumoperitoneum) is indicative of perforation. Gas in the portal venous system may be a sign of advanced disease (Figs 18.33–18.35).

During hospitalization, the patient was found to be in respiratory distress with use of accessory muscles. The code status of the patient stated not to resuscitate or intubate. The saturation was 93% on room air. Chest x-ray at the time revealed an infiltrate consistent with pneumonia. He was started on empiric treatment with vancomycin and piperacillin-tazobactam for seven days, methylprednisolone, bronchodilators, and non-rebreather mask with FiO2 of 40% for the treatment of hypoxic respiratory failure and hospital-acquired pneumonia. On hospital day 12, he was found to be in respiratory distress now requiring BiPAP machine. This machine was used for approximately 18 h. The diagnosis of pulmonary embolism was excluded by performing a CT angiogram. An incidental finding of portomesenteric venous gas was noted. Therefore, a CT of the abdomen and pelvis was obtained. This study showed large amounts of stool burden throughout the gastrointestinal tract and thickening of stomach walls (body and fundus) shown in Figures 1 and 2 (inset). This was suggestive of pneumatosis intestinalis and EG.

The following maternal variables were studied: clinical or histological chorioamnionitis, diabetes mellitus, hypertension, receipt of antenatal steroids, and history of substance abuse, including cocaine, narcotics, nicotine, and cannabis. Neonatal data were collected for the first 14 days after birth and included gestational age; birth weight; sex; race; vaginal or cesarean section delivery; Apgar scores at 1 and 5 minutes of life; highest mean airway pressure and fractional inspired oxygen on postnatal days of life 1 and 7; receipt of surfactant in doses >1; patent ductus arteriosus as diagnosed by echocardiogram and treated medically or surgically; air leak syndrome including pneumothorax, pneumomediastinum, and pneumopericardium; necrotizing enterocolitis; spontaneous intestinal perforation; and intraventricular-periventricular hemorrhage of any grade. The diagnosis of necrotizing enterocolitis was made if the infant presented with stage IIA or higher of the modified Bell’s criteria. The diagnosis of spontaneous intestinal perforation was made with radiologic findings of pneumoperitoneum in the absence of pneumatosis intestinalis and portal venous air, further confirmed by the surgical findings of an isolated bowel perforation with an otherwise visually and histopathologically normal bowel. The neonatal outcome variables included in the study were periventricular leukomalacia, ventriculomegaly, death before discharge, and oxygen dependence at 36 postmenstrual weeks of life (bronchopulmonary dysplasia).

He was discharged home following the procedure and was scheduled to receive eculizumab 1200 mg every 2 weeks. Approximately 6 weeks after discharge, he began to decline functionally and had episodes of diarrhea leading to hyponatremia. A repeat CT scan of the chest/abdomen/pelvis showed extensive pneumatosis intestinalis of the large bowel with evidence of portal venous gas, concerning for bowel ischemia. He was readmitted to the hospital. Evaluation by general surgery led to the decision not to pursue further surgical intervention due to the high risk of mortality associated with his state. During this admission, goals of care were addressed, and he signed a do-not-resuscitate order and was referred to hospice care. The patient died before he could be discharged.
