Invaginaties bij kinderen: niet altijd ileocoecaal

- Three patients, two girls aged 10 and a boy aged 11, suffered from secondary intussusception. Two of the cases were mistakenly managed as an idiopathic or classic intussusception. Hydrostatic reduction with a contrast enema was thought to be successful when retrograde influx in the ileum was seen. As the intussusception recurred, a diagnostic laparoscopy was performed followed by laparotomy and surgical treatment. In both cases an ileo-ileal intussusception was found. In one case the lead point was a malignant lymphoma, in the other case probably an area of vasculitis associated with Henoch Schönlein purpura. The enema had only repositioned the ileocolic part of the intussusception. In the third patient, the ileo-ileal intussusception resolved spontaneously. Due to the location of the intussusception, a lead point was suspected and a laparoscopy was performed. A Meckel’s diverticulum was found and resected. The importance of looking for a lead point is emphasized when dealing with an intussusception in children over the age of 3, or with evidence of underlying disease. In such cases, the relative value of a contrast enema for diagnosis and reposition is emphasised. There should be a low threshold for further investigation, including diagnostic laparoscopy.
