Y1 - 2017 N1 - T2 - Comprehensive Pediatric Hospital Medicine, 2e AB - Obstruction of the gastrointestinal (GI) tract can be due to a wide range of causes with many similarities in clinical presentation. Abdominal pain, early satiety or anorexia, and vomiting are common, with abdominal distention being more common with lower tract blockage. Nonbilious emesis is seen in conditions that occur proximal to the sphincter of Oddi or early in the course of abnormalities occurring more distally. Conversely, bilious emesis is seen when obstruction or dysfunction occurs distal to the duodenum.
