Abstract:
OBJECTIVE:To study the clinical features and etiology of abdominal distension in children with different ages.
METHODS:A retrospective analysis was performed for the clinical data of 1 561 children who were admitted due to abdominal distension from January 2013 to October 2016, including clinical manifestations, radiological examination, pathological results, and disease diagnosis.
RESULTS:Among the 1 561 children, there were 823 neonates (aged <28 days), 307 infants (aged 28 days to 1 year), 186 toddlers (aged 1-3 years), 120 preschool children (aged 3-6 years), 106 school-aged children (aged 6-12 years), and 19 adolescents (aged 12-17 years). Vomiting was the major associated symptom in neonates, infants, toddlers, and school-aged children, abdominal pain was the major associated symptom in pre-school children, and vomiting and abdominal pain were the major associated symptoms in adolescents. Hypoactive bowel sound was the major accompanying sign in neonates and infants, and abdominal tenderness was the major accompanying sign in the other four age groups. Plain abdominal radiograph showed intestinal inflation in neonates and intestinal inflation with an air-fluid level in the other five age groups. Histopathological examination was performed for 339 children and the pathological results of intestinal tissue showed small, few, or poorly developed submucosal ganglion cells in neonates, intestinal inflammation/bleeding/necrosis in infants, and appendicitis in the other age groups. Necrotizing enterocolitis was the main cause of abdominal distension in neonates (34.4%), and intestinal obstruction was the main cause in infants (36.8%), toddlers (52.2%), pre-school children (51.7%), school-aged children (62.3%), and adolescents (52.6%).
CONCLUSIONS:Vomiting is a common symptom in children with abdominal distension in all age groups. Neonates and infants with abdominal distension often present with hypoactive bowel sounds, and children over 1 year old mainly suffer from abdominal tenderness. Necrotizing enterocolitis is the most common cause of neonatal abdominal distension, and abdominal distension in the other age groups is mainly attributed to intestinal obstruction.
