Small Bowel Intussusception Diagnosed on Ultrasound – What Does it Mean for a Pediatric Surgeon? The Diagnostic Value of Ultrasound for Intussusception

Abstract

Aims of the Study: The evaluation of the clinical value of ultrasound diagnosis of small bowel intussusception (SBI) and to establish sensitivity, specificity and diagnostic odds ratio of ultrasonography for ileocecal intussusception. Methods: Retrospective analysis of the patients' data with the suspected intussusception when ultrasonography (US) was performed was carried out during the last 10 years period in the Department of Pediatric Surgery and Admission Department. The clinical outcome of the patients with ultrasonographically diagnosed small bowel intussusception was analyzed. The sensitivity, specificity and diagnostic odds ratio with 95% Cl of US was calculated for the diagnosis of ileocecal intussusception. Results: During 10 years period we had 214 cases of confirmed ileocecal intussusception. Additionally there were 62 cases of ultrasonographically diagnosed small bowell intussusception (23% of all intussesceptions). Just one of them required surgery, the symptoms resolved spontaneously for the others. The majority of those patients had no any other diagnostic procedure. Some had air enema with no evidence of intussusception; few of them had barium series without any symptoms of obstruction. There were 4 cases of surgically confirmed SBI (1,9% of all intussusceptions), just one was correctly diagnosed ultrasonographically, others were diagnosed as ileocecal intussusception. The sensitivity of US was 93% (Cl 89-96%), specificity 96% (Cl 95-97%), diagnostic odds ratio 414 (Cl 214-798) for the diagnosis of ileocecial intussusception. [...].
