Dr. Jonathon Gisser, a pediatric gastroenterologist at Nationwide Children’s Hospital, researched and created a process called Gastric Secretion Reinfusion (GSR) to help salvage gastric fluids by reinfusing them into the jejunum.

Gastrojejunostomy (GJ) tubes cause increased vomiting and/or gastric drainage in patients due to gastric outlet obstruction. The small intestine needs gastric fluids to prevent dehydration, dysmotility, malabsorption, malnutrition, electrolyte imbalances and increased gastric output because they are rich in electrolytes, enzymes and hormones. Currently, gastric fluids are typically discarded and replaced by nutrient-impoverished, exogenous fluids like intravenous fluids (IV). By implementing the Gastric Secretion Reinfusion technique, patients will experience decreased incidences of electrolyte abnormalities, vomiting and reliance on parenteral access and Total Parenteral Nutrition (TPN). Additionally, they will also experience an increase in tolerance of jejunal feeds and improved nutrition.
