A 78-year-old man with advanced oropharyngeal cancer presented with a therapy-resistant wound infection at the site of a previously placed percutaneous endoscopic gastrostomy (PEG). The infection required PEG-tube removal, performed using the cut-and-push technique. Owing to complete esophageal obstruction, conventional transoral endoscopic re-insertion of a new PEG was not feasible. ( Fig. 1 ).

A slim nasal gastroscope was advanced through the gastrostomy tract to access the stomach ( Fig. 2 ). Under direct endoscopic visualization, a new gastric puncture was performed in an unaffected region, followed by gastropexy and PEG reinsertion via the push technique. The procedure was carried out under sterile conditions without any complication ( Video 1 ).

Trans-gastrostomy PEG placement is a valuable alternative in patients with complete esophageal obstruction where conventional access is impossible. Careful patient selection and strict adherence to sterile technique enable the safe reinsertion of a PEG at a new gastric site, avoiding the need for surgical gastrostomy.
This case illustrates the feasibility and safety of trans-gastrostomy endoscopy for PEG replacement in complex anatomical situations and highlights its role as a minimally invasive salvage technique.
