Transnasal esophagogastroduodenoscopy for placement of nasoenteric feeding tubes in patients with severe upper gastrointestinal diseases.

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.
