Percutaneous endoscopic gastrostomy (PEG) -push and pull methods need reinsertion of endoscopy for the observation of a relation between gastric wall and a PEG catheter bumper to confirm correct placement. There is a possibility that the difficult reinsertion of endoscopy induces patient's stresses and aspiration pneumonia. We tested a guide wire (GW) using new method for reinsertion of endoscopy in PEG-push method.
This new method is modified PEG-push method. The inserted GW exits the body from the patient's abdomen and mouth. Slide the device, dilator end first, over the end of the GW that is exiting the patient's mouth. Maintain firm tension on both ends of the GW as the device passes through the oropharynx and into the stomach. As the firm, tapered end of the device is pushed through the anterior abdominal wall it will also push the cannula out. Oral end of the inserted GW is introduced into the endoscopic channel with a grasping snare. Tip of the endoscope becomes near the bumper of a PEG catheter. Pull the inserted GW and tapered end of the device of a PEG catheter. The bumper of a PEG catheter and tip of the endoscope pass easily and quickly through the pharyngoesophageal junction and into the stomach.
This new GW using method is significantly reduced the reinsertion-time and shortened the rate compared with conventional method.
This new method enables us to easy and quick reinsertion of endoscopy in PEG-push method and reduces patient's damages such as stresses and aspiration pneumonia.
