Journal Club – “Early Oral Protein-Containing Diets Following Elective Lower Gastrointestinal Tract Surgery”

Although fast track protocols for elective lower gastrointestinal tract surgery commonly include an early feeding component, the most recent meta-analyses looking at studies in this area have failed to show a conclusive improvement in patient outcomes (2). However, this and previous analyses have pooled the assessment of protein-containing and non-protein liquid diets. This recently published meta-analysis by Pu et al. (1), which examined outcomes after an early oral protein-containing diet, suggests that current guidelines should be upgraded to a grade A recommendation supporting an oral protein-containing diet commenced before the end of postoperative day 1 after elective lower gastrointestinal surgery in adults.
