ABSTRACT
This chapter presents a case of a newborn male infant with a birth weight of 3.2 kg. There was no passage of meconium in the initial 24–48 hours, and this was associated with poor feeding, abdominal distension, and bilious vomiting. Malrotation has been excluded on an upper gastrointestinal study. In order to confirm the diagnosis it opens a colostomy that performs contrast enema attempt to pass 10—12-F catheter into the anus. The differential diagnosis of newborn infant with bilious vomiting should include malrotation. It is important to exclude this in the first instance with an upper gastrointestinal contrast. This case of rectal atresia represents 1" of all anorectal malformations and that anal stenosis can have a similar appearance. It is safer to perform a colostomy and mucous fistula in the newborn period so that a distal colostogram can be performed to establish the position of the rectum and the presence of any fistulous communication with the urinary tract.
