PURPOSE: Accurate clinical diagnosis of acute appendicitis is more difficult in children since they may not be able to communicate their complaints adequately, and findings on physical examination may be nonspecific.The uncertainty in diagnosis may lead to a delay of surgery or to unnecessary laparotomy. Prompt diagnosis is important due to their complications such as perforation, abscess formation, and peritonitis. The authors conducted this study in order to find out usefulness of ultrasonography in diagnosis of acute appendicitis in children. METHODS: The authors was performed ultrasonographical examination to 290 children with abdominal pain under the age of 15 during a recent 16-months period from January 1994 to April 1995. High-resolution ultrasonography was used according to the graded compression method. The ultrasonographic findings were correlated with pathologic outcome in 87 cases. RESULTS: 1) Among 290 patients with abdominal pain, acute appendicitis was 81 cases (27.9%), and there were mesenteric lymphadenitis, terminal ileitis, intussusception, acute gastroenteritis, and nonspecific findings. 2) Sex ratio of acute appendicitis was 1.53:1. The acute appendicitis was occurred 13.6% in under the age of 5 and 86.4% in over the age of 6. Mean age was 10.6 3) The most frequent symptom was abdominal pain followed by vomiting, fever, nausea, and diarrhea. 4) Leukocytosis (>10,000/cu.mm) was occurred in 71 of 81 (87.7%) cases of acute appendicitis and 24 of 28 (85.7%) cases of acute appendicitis with perforation. 5) The perforation rate was higher in delayed diagnosis and in younger children. 6) Ultrasonography had a sensitivity of 97.5%, specificity of 96.2%, positive predictive value of 90.8%, and negative predictive value of 99.0% on diagnosis in acute appendicitis. CONCLUSIONS: Upon the above results, the authors were able to conclude that graded compression ultrasonography had high sensitivity and specificity and was useful for the diagnosis of acute appendicitis in children. And the ultrasonography can be applied as rapid, noninvasive, and well-tolerated investigation. So, it has diagnostic value as screening test in children whose chief complaint is abdominal pain.

PURPOSE: Acute febrile illness in children frequently accompanies with abdominal symptoms such as vomiting, diarrhea, and abdominal pain, even if its etiology is not occured from the gastrointestinal tract. If the etiology of fever was unknown and the fever was accompanied with abdominal symptoms, we should be concerned about whether the etiology of fever was originated from the gastrointestinal tract or interpretated from the abnormality in the gastrointestinal tract. This study was performed to evaluate the diagnostic value of abdominal ultrasonography in patients with fever and abdominal symptoms. METHODS: We reviewed retrospectively the medical records of abdominal ultrasonographic (US) findings of 60 cases of acute febrile illness with abdominal symptoms at department of Pediatrics, Ulsan Dongang General RESULTS: (100%), splenomegaly in 4 cases (66.7%), ileocecitis in 1 case (16.7%), enlarged mesenteric lymph nodes and splenomegaly in 4 cases (66.7%), enlarged mesenteric lymph nodes, splenomegaly and ileocecitis in 1 cases (16.7%). 6) The enlarged mesenteric lymph nodes and the abnormalities around the appendix were seen in 7 cases (11.7%), which were confirmed as appendicitis all. 7) The thickening of wall in urinary bladder was seen in 2 cases (3.3%) of acute cystitis and acute hemorrhagic cystitis. 8) The subtle thickening of wall in colon was seen in 1 cases (1.7%) of shigellosis. CONCLUSIONS: The enlarged mesenteric lymph nodes, splenomegaly and ileocolitis on the abdominal ultrasonography in patients with fever and abdominal symptoms aree suggestive findings of typhoid fever. The enlarged mesenteric lymph nodes and the abnormalities around the appendix on abdominal ultrasonography make the rapid diagnosis of acute appendicitis and its complications, when physical examination is difficult in small children and diagnosis of their illnesses is obscure in patients with fever and abdominal pain.
