Percutaneous endoscopic gastrostomy: a dislodgement complication due to a moving hiatal hernia.

Objectives: Frail patients with malnourishment due to an esophageal condition and dysphagia are often unamenable to safe surgery. Thus, in high-risk patients, less invasive techniques such as percutaneous endoscopic gastrostomy (PEG) are regarded as a safer choice. Nevertheless, as described here, PEG insertion can have rare serious complications.Materials and methods: We report the case of a frail patient with dysphagia due to a large Zenker's diverticulum and concomitant giant hiatal hernia. To improve her nutrinitional status before surgery she received a PEG after endoscopic repositioning of the hernia.Results: Within 48 hours after hernia repositioning and PEG insertion, a severe adverse event ensued: dislodgement of the PEG due to stomach reherniation.Conclusions: This case challenges the use of PEG as an only means for gastric fixation for hiatal hernia.
