Small Bowel Congenital Anomalies: A Review and Update

Abstract

The small intestine is a complex organ system that is vital to the life of the individual. There are several congenital anomalies that occur and present most commonly in infancy; however, some may not present until adulthood. Most congenital anomalies of the small intestine will present with obstructive symptoms, whereas some may present with vomiting, abdominal pain, and/or gastrointestinal bleeding. Various radiologic procedures can aid in the diagnosis of these lesions that vary depending on the particular anomaly. The congenital anomalies of the small intestine discussed include Meckel diverticulum, duodenal web, duodenal atresia, jejunoileal atresia, and intestinal duplications.
