Pneumatic reduction using air has recently become popular for the initial non-surgical management of intussusception. Since carbon dioxide (CO2) is rapidly absorbed from body surfaces, it should theoretically result in less cramping and distension following reduction. We reviewed our recent experience with the pneumatic reduction of intussusception using CO2 in 26 children. In 22 of these the intussusception was reduced (85%). There was one performation with CO2; the patient did not suffer any postoperative complications. Five additional children who had been treated unsuccessfully with barium had intussusception subsequently reduced with CO2. Following CO2 reduction, most children were fed within hours, and there were no instances of significant abdominal distension or cramping. We conclude that pneumatic reduction of intussusception using CO2 is safe and effective, and has the theoretical advantage of more rapid absorption from the gastrointestinal tract than air.

The nonoperative treatment of intussusception is done by fluoroscopy, however, false-positive and negative images may lead to unnecessary operations. The aim of this study was to evaluate the feasibility of laparoscopy in pneumatic reduction. Surgical ileoileocolic intussusception was performed in 27 dogs. Sixteen dogs were observed for 3 days (group A), and 11 were observed for 5 days (group B). Laparoscopy was performed in the intussuscepted dogs during pneumatic reduction. Under general anesthesia, a 10-mm trocar was inserted supraumblically in the midline, and the laparoscope was introduced. The intussuscepted bowel was observed on the video monitor. A 5-mm trocar was inserted in the right upper quadrant. The mesentery of the terminal ileum was manipulated using grasping forceps to assist reduction. CO2 was insufflated into the rectum using a Foley catheter, and the reduction was observed on the video monitor. The success rate was 94% (mean reduction time, 2.5 minutes +/- 1.0) for group A and 100% (mean reduction time, 3.7 minutes +/- 0.8) for group B. Bowel perforation was observed in one dog, and recurrence of intussusception in another. The authors claim that observing the bowel on the video monitor may help in the differential diagnosis and reduction of difficult cases such as ileoileocolic and delayed intussusceptions. Therefore, unnecessary open surgery may be prevented.
