Aspiration associated with long-term gastric versus jejunal feeding: a critical analysis of the literature.
Neurogenic oropharyngeal dysphagia (NOD), common among rehabilitation populations, is a risk factor for aspiration. A history of recurrent aspiration is an indication for gastric feedings according to some physicians, although according to others it is a contraindication to gastric feedings and an indication for jejunal feedings. In light of these divergent opinions, the literature from 1978 to 1989 on aspiration in patients with severe NOD was examined to determine whether empiric evidence supports the preferential use of a gastric or a jejunal feeding site. The data reviewed did not support the preferential use of either feeding site. Forty-five studies met inclusion criteria. Two studies compared aspiration rates in patients receiving gastric feedings to those receiving jejunal feedings. Another study reported complications with gastric and jejunal feedings but did not compare the two feeding groups. Forty-two studies evaluated either gastric (36) or jejunal (6) feedings. The relative risks of aspiration associated with gastric and jejunal feedings could not be determined reliably because of heterogenous and inadequately described patient populations, poorly described data collection methods, nonoperational definitions of aspiration, small sample sizes, and unspecified time frames, feeding protocols, and care settings. Few data about long-term jejunal feeding, extremely variable data on the risk of aspiration during long-term gastric feeding, and much variation in clinical practice support a need for further research designed to determine the proper role for gastric and jejunal feeding. Recommendations for research and the role of the rehabilitation team in determining the best enterostomy site are suggested.
