Gastrointestinal Obstruction T2 Rudolph's Pediatrics, 22e YR 2011 FD 2011 PB The McGraw-Hill Companies PP New York, NY SN 978-0-07-149723-7 LK accesspediatrics.mhmedical.com/content.aspx?aid=7035989 RD 2024/04/19 AB Gastrointestinal obstructions are categorized according to etiology as either congenital or acquired. These broad categories are not mutually exclusive. For example, congenital lesions of the intestine such as an enteric duplication or Meckel diverticulum may not cause obstruction until later in life. Congenital anatomic defects and acquired disorders of the intestine presenting in the first 30 days of life are characterized as neonatal intestinal obstruction.
