Contamination of single fluid-filled intragastric balloons with orogastric fluid is not associated with hyperinflation: an ex-vivo study and systematic review of literature.

ABSTRACT:

Background

Spontaneous hyperinflation is reported to the Food and Drug Administration as a complication of intragastric balloons. It is postulated that orogastric contamination of the intragastric balloon may cause this phenomenon. We sought to investigate the effects of intentional balloon contamination with gastric contents on intragastric balloon perimeter and contents, whether methylene blue plays a role in preventing spontaneous hyperinflation, and review the available literature on spontaneous hyperinflation.

Methods

Four pairs of balloons with different combinations of sterile saline, orogastric contaminants, and methylene blue were incubated in a 37 °C water bath for six months to simulate physiological conditions with serial measurements of balloon perimeter. Our fi
