We present the case of a 77-year-old male who was referred for magnetic resonance (MR) enteroclysis because of small bowel subobstruction. To optimise small bowel distention during MR, a nasojejunal balloon catheter was placed to perfuse iso-osmotic water solution into the small bowel. However, after deflation of the balloon, the catheter could not be removed by gentle traction. Subsequently, computed tomography (CT) of the abdomen revealed that the catheter was strangulated deep in the jejunum and traction resulted in painful backward intussusception of the small bowel. In order to avoid surgical intervention, we decided to perform urgent proximal double-balloon enteroscopy to remove the enteroclysis catheter. Under fluoroscopic guidance, the enteroscope was introduced into the jejunum until the tip of the enteroscope reached the tip of the catheter. By straightening the enteroscope, the catheter could then be retracted from the jejunum, using the enteroscope as a guide wire along the catheter. Urgent surgical intervention was avoided and the patient completely recovered the same day.
