Chapter 43: The Child With a Gastrointestinal Alteration

Congenital defects receive substantial coverage, starting with cleft lip and palate, where nursing management emphasizes adaptive feeding strategies to prevent aspiration prior to surgical reconstruction. Esophageal atresia paired with tracheoesophageal fistula represents a surgical emergency presenting with respiratory distress, requiring immediate intervention to separate respiratory and digestive pathways. Abdominal wall defects including gastroschisis, omphalocele, and various hernia types are discussed alongside their surgical correction timelines. Motility disorders feature prominently, particularly gastroesophageal reflux disease managed through positional therapy, formula modification, and surgical fundoplication when conservative approaches fail. Constipation and encopresis are addressed through behavioral interventions and dietary modification strategies. The chapter extensively explores inflammatory and infectious etiologies, with acute gastroenteritis emphasizing fluid and electrolyte restoration via oral rehydration protocols. Inflammatory bowel disease variants are differentiated by their pathophysiological mechanisms and distinct nutritional demands. Appendicitis is identified as the primary surgical emergency in pediatric populations, with characteristic pain migration patterns guiding clinical assessment. Obstructive conditions including pyloric stenosis, intussusception, and Hirschsprung disease are detailed with their defining clinical presentations and appropriate therapeutic interventions. Malabsorption syndromes such as celiac disease and lactose intolerance require dietary management and long-term nutritional monitoring. Hepatic complications encompassing viral hepatitis transmission, biliary atresia requiring hepatic reconstruction or transplantation, and cirrhotic sequelae complete the clinical overview.
