Abstract
Ultrasonographic examination plays an important role in non-invasive and prompt screening examinations in detecting abdominal diseases. In this review, the author's experience of the usefulness and pitfalls of ultrasonographic examinations in children with gastrointestinal symptoms is presented. A total of 1,000 cases of children who underwent ultrasonographic evaluation in the Department of Pediatrics, Pusan National University Hospital were reviewed. The main causes leading to ultrasonographic evaluation were abdominal pain (43.9%), vomiting (17.3%), elevated liver enzymes (11.8%), and jaundice (9.8%). Abnormal ultrasonographic findings accounted for 57.9% of cases. The major abnormal findings were mesenteric lymphadenitis (29.2%), fatty liver (12.1%), hepatitis (6.4%), hepatosplenomegaly (6.2%), and acute appendicitis (4.8%). The major findings in children with abdominal pain were mesenteric lymphadenitis (32.6%), intussusception (2.7%), and acute appendicitis (2.7%). The major findings in children with vomiting were mesenteric lymphadenitis (12.7%), hypertrophic pyloric stenosis (10.4%), acute appendicitis (3.5%). The major ultrasonographic findings in children with urinary tract diseases were hydronephrosis (45.4%), urolithiasis (21.5%) and cystic renal disease (18.1%). Ultrasonography performed by pediatricians is advantageous because pediatricians are able to perform the procedure with clinical information at the right time.
