Earlier today, your colleague in the pediatrics department found that Prisca Cabrini, a (currently) 10-hour-old neonate, had esophageal atresia with a distal tracheoesophageal fistula (EA-TOF). She is in your ward now, awaiting surgical correction.

You quickly go through Prisca's records. You note that her birth weight was 2600 g and that she has no other congenital anomalies. Her respiratory examination was normal. Plain x-rays of the chest confirmed EA-TOF and showed clear lung fields. Echocardiography revealed a structurally and functionally normal heart.

You also note that the gap between the proximal and distal esophageal pouches is 2 cm.
