The Effect of Semi-solid Feeding After Percutaneous Endoscopic Gastrostomy (PEG) on the Incidence of Aspiration Pneumonia and Postoperative Length of Stay

The Effect of Semi-solid Feeding After Percutaneous Endoscopic Gastrostomy (PEG) on Clinical Outcomes, Specifically the Incidence of Aspiration Pneumonia and Postoperative Length of Stay

Percutaneous endoscopic gastrostomy (PEG) is a minimally invasive procedure for long-term enteral tube feeding in patients with insufficient oral intake. Although peristomal site infection is often noted as the most common adverse event after PEG tube placements, it is seldom life-threatening and considered a minor adverse event. Feeding-related adverse events have been identified as the main cause of death after PEG, with up to 50% of postoperative early mortality (30 days) being attributed to aspiration pneumonia. This may be related to the persistence of gastroesophageal reflux (GER) of enteral feed after gastrostomy, even though PEG have been demonstrated to be superior to nasogastric tube feeding in terms of preventing GER. It has been more than a decade since semi-solid feeds were developed as an alternative to conventional liquid feeds to prevent feeding-related adverse events. Unfortunately, there is limited published literature on this topic despite the wide usage of this feeding method in Japan. Amidst the growing popularity of this method and the introduction of National Healthcare Insurance coverage for semi-solid feed prescriptions, we initiated a semi-solid feed protocol along with our existing post-PEG feeding protocols in 2014.
