Modified Radiology-Guided Percutaneous Gastrostomy (MRPG) for Patients with Complete Obstruction of the Upper Digestive Tract and Who are without Endoscopic or Nasogastric Access

ABSTRACT

OBJECTIVE: We wanted to report on our experience with modified radiology-guided percutaneous gastrostomy (MRPG) without endoscopic or nasogastric access for treating patients with complete obstruction of the upper digestive tract. MATERIALS AND METHODS: Fourteen oncology patients (13 had hypopharyngeal cancer and 1 had upper esophageal cancer) with complete obstruction of the upper digestive tract were recruited. Conventional percutaneous endoscopic gastrostomy (PEG) and radiologic (fluoroscopy-guided) percutaneous gastrostomy (RPG) were not feasible in all the patients. An MRPG technique (with a combination of ultrasound, an air enema and fluoroscopic guidance) was performed in these patients. RESULTS: We achieved successfully percutaneous gastrostomy using the modified technique in all patients without any major or minor complications after the procedure. CONCLUSION: A modified radiology-guided percutaneous gastrostomy technique can be safely performed in patients who failed to receive conventional PEG or RPG due to the absence of nasogastric access in the completely obstructed upper digestive tract.
