The present prospective observational study investigates the safety of transnasal percutaneous endoscopic gastrostomy (T-PEG) carried out by a single physician using an ultrathin endoscope.


A single endoscopist attempted the unsedated transnasal insertion of a 20-Fr PEG tube using a pull-method in 31 dysphagic patients: 11 females and 20 males aged 76.5±10.6(46-96)years, using a 5-mm-diameter endoscope. The indications for PEG, cardiopulmonary function before and after T-PEG, operation time, success or failure, and any immediate adverse events that occurred during each procedure were recorded. Complications, including peristomal infection, systemic infection, tube lifespan, and patient mortality were monitored throughout the post-T-PEG follow-up period.


Thirty (96.8%) of the transnasal PEG insertions were successful. The mean operation time was 14.7±2.9 (10-20) min, and cardiopulmonary function did not change before and after T-PEG. Complications included three (10%) cases of epistaxis, eight (26.6%) cases of minor Pseudomonas wound infection and two cases of Foley-related urinary tract infection (UTI). No self-extubation was observed, and the mean lifespan of the PEG tubes was 10.7±2.2months. Four patients died from pneumonia 10months after T-PEG insertion.


Unsedated T-PEG insertion carried out by a single physician is a feasible and safe procedure. No major complications or mortality were observed following the procedures; only minor Pseudomonas aeruginosa wound infections were noted. It is an alternative method for dysphagic patients when transoral insertion of endoscopy is impossible.
