Trajectory of gastrointestinal function after laparoscopic colorectal surgery within an enhanced recovery pathway

Background: Early identification of colorectal surgery patients predicted to have uneventful gastrointestinal recovery may allow for early discharge. Our objective was to identify trajectories of gastrointestinal recovery within a colorectal surgery enhanced recovery pathway. Methods: Data from 2 prospective studies enrolling adult patients undergoing elective laparoscopic colorectal resection at a specialist colorectal referral center were analyzed (2013–2019). All patients were managed according to a mature enhanced recovery pathway with a 3-day target length of stay. Postoperative gastrointestinal symptoms were collected daily and expressed using the validated I-FEED score. Latent-class growth curve (trajectory) analysis was used to identify different I-FEED trajectories over the first 3 postoperative days. Results: A total of 192 patients were analyzed. Trajectory analysis identified 3 distinct trajectories: trajectory 1 had no gastrointestinal symptoms (41%); trajectory 2 had mild early symptoms with improvement over time (48%); and trajectory 3 had gastrointestinal symptoms that significantly worsened between postoperative days 1 and 2 (11%). I-FEED score ≤1 on postoperative day 1 predicted trajectory 1. Trajectory 1 had the best clinical outcomes, whereas trajectory 3 had the worst. Conclusion: I-FEED trajectory over postoperative days 1–3 was associated with clinical outcomes and may be used to predict gastrointestinal recovery. Findings from this study may inform clinical decision making regarding early hospital discharge within colorectal enhanced recovery pathways. © 2021 Elsevier Inc.
