title: [CT-guided percutaneous endoscopic gastrostomy: a successful method if transillumination is not possible].
abstract: OBJECTIVE
  If transillumination is not possible, percutaneous endoscopic gastrostomy (PEG) is contraindicated. In these cases the stomach had so far to be punctured directly during radiological monitoring. A new method is described which combines endoscopy and computed tomography (CT) for performing a percutaneous endoscopic gastrostomy.
  
  
  METHODS
  Among 189 patients who were to have the procedure there were eleven (nine men, two women) in whom transillumination was not possible. After endoscopic insufflation of air PEG was done under CT guidance, using the common pull-through technique.
  
  
  RESULTS
  The combined method was successful in ten of the eleven patients without complication. In one patient with hepatomegaly and interposition of the transverse colon PEG was not possible even with CT guidance.
  
  
  CONCLUSIONS
  The combined endoscopic-radiological method is practicable and safe in cases in which transillumination is not possible. There are several advantages compared with direct puncturing: The common pull-through technique can be used; radiological exposure is low and other clinically relevant findings may be revealed by the endoscopy.
