OBJECTIVE: To evaluate the feasibility and efficacy of small-caliber transnasal esophagogastroduodenoscopy for the placement of nasoenteric feeding tubes (NET) in patients with severe upper gastrointestinal (GI) diseases.
METHODS: Between January 2007 and March 2010, 51 patients underwent transnasal endoscopy for the placement of NET in Peking University Third Hospital. Indications for NET included esophageal stricture or gastric outlet obstruction because of corrosive esophagitis or gastritis, partial obstruction due to malignancy, stenosis in stoma or efferent loop, gastroparesis, metallic stent in upper GI tract, tracheoesophageal fistula, severe acute pancreatitis, anorexia nervosa and intensive care patients. The tubes were endoscopically placed using the guidewire technique. The position of the tube was confirmed by the immediate second endoscopy or abdominal X-ray. If the initiate placement was not correct, an adjustment or a second placement was conducted immediately.
RESULTS: Initial post-pyloric placement of NET was achieved in 43 of 51 patients (84.3%), but the total success rate reached 98.0% (50/51) after the second placement. The time required for the procedure ranged from 10 to 35 min, with a median time of 20.4 min. Epistaxis occurred in 2 patients. There were no complications of hemorrhage, perforation or aspiration.
CONCLUSION: The transnasal endoscopic placement of NET was feasible in patients with upper GI diseases, especially in those with changed anatomy.
