Early Versus Delayed Feeding After Placement of a Percutaneous Endoscopic Gastrostomy: A Meta-Analysis

BACKGROUND: Traditionally, tube feedings have been delayed after percutaneous endoscopic gastrostomy (PEG) placement to the next day and up to 24 h postprocedure. However, results from various randomized controlled trials (RCTs) indicate earlier feeding may be an option. We conducted a meta-analysis to analyze the effect of early feedings (<= 4 h) after PEG placement. METHODS: Multiple databases were searched (November 2007). Only RCTs on adult subjects that compared early (<= 4 h) versus delayed or next-day feedings after PEG placement were included. Meta-analyses for the effect of early and delayed feedings were analyzed by calculating pooled estimates of complications, death <= 72 h, and significant increases in postprocedural gastric residual volume during day 1. RESULTS: Six studies (N = 467) met the inclusion criteria. No statistically significant differences were noted between early (<= 4 h) and delayed or next-day feedings for patient complications (OR 0.86, 95% CI 0.47-1.58, P = 0.63) or death in <= 72 h (OR 0.56, 95% CI 0.18-1.74, P = 0.31). A statistically significant increase in gastric residual volumes during day 1 was noted (OR 1.80, 95% CI 1.02-3.19, P = 0.04). CONCLUSIONS: Early feeding <= 4 h after PEG placement may represent a safe alternative to delayed or next-day feedings. Although an increase in significant gastric residual volumes at day 1 was noted, overall complications were not affected.
