Half-solidification of nutrient does not decrease gastro-esophageal reflux events in patients fed via percutaneous...

Area of Science:

• Gastroenterology
• Clinical Nutrition
• Medical Devices

Background:

• Percutaneous endoscopic gastrostomy (PEG) feeding is crucial for patients with swallowing difficulties.
• Reflux-induced aspiration pneumonitis is a significant risk in PEG-fed patients.
• Gastro-esophageal reflux (GER) management is vital for patient safety.

Purpose of the Study:

• To evaluate the impact of half-solidifying nutrient formula on GER in PEG-fed patients.
• To compare acidic and non-acidic GER events between half-solid and liquid nutrient feeding.
• To assess the efficacy of modified nutrient consistency in preventing GER.

Main Methods:

• Esophageal multichannel intraluminal impedance and pH (MII-pH) monitoring was employed.
• 14 elderly patients receiving PEG feeding participated in the study.
• GER events were quantified during 4 hours post-feeding with both half-solid and liquid nutrients.

Main Results:

• No significant difference in total GER events was observed between half-solid and liquid feeding.
• A trend towards a higher number of acid reflux events was noted with half-solid feeding.
• The study found no benefit of half-solidification in reducing overall GER.

Conclusions:

• Half-solidification of nutrients is not effective in preventing GER in PEG feeding.
• Current feeding strategies may require re-evaluation for GER prevention.
• Further research into optimal nutrient formulations for PEG feeding is warranted.
