BackgroundIntussusception is the most common cause of abdominal emergency in early childhood. The majority of cases are ileocolic type of intussusception. Only few reports concerning small bowel intussusception have been reported.Patients And MethodWe retrospectively reviewed the clinical records and imaging findings of all patients with the diagnosis of intussusception (comparing small bowel intussusception with ileocolic type of intussusception), which were documented by ultrasound in the period April 1997 to January 2001. The routine ultrasound scans included an evaluation of the entire abdomen using sector and linear transducers of high frequency (5 - 7.5 MHz) and power doppler ultrasound.ResultsA total of 22 patients with small bowel intussusception (9 female, 13 male) and 29 patients diagnosed to suffer from ileocolic intussusception (10 female, 19 male) were identified and treated. Children with small bowel intussusception were significant older in comparison to children with ileocolic type of intussusception (median age 50 vs. 11 months). In our series the presenting symptoms of patients with small bowel intussusception consisted of abdominal pain (86 %) and vomiting (36 %). The initial clinical symptoms of patients with ileocolic intussusception were abdominal pain (100 %), vomiting (72 %) and/or rectal fresh blood (35 %). Small bowel intussusception was an incidental finding in 3 asymptomatic patients (14 %). Hydrostatic reduction was attempted in 14 % of children with small bowel intussusception (vs. 93 % of children with ileocolic intussusception), one patient needed operative treatment (vs. 21 %). Outcome in all patients was favorable.ConclusionThe high percentage of patients with small bowel intussusception observed may relate to increased use of abdominal ultrasound in children presenting with abdominal pain and improvements in resolution and quality of the images. Small bowel intussusceptions in our series were in the majority of cases short-segmented, self-limited and without a lead point. In comparison to patients with ileocolic intussusception the presenting symptoms of small bowel intussusception are less acute.
