Objective: The aim of this single-center cohort study was to compare direct oral feeding (DOF) to standard of care after a minimally invasive esophagectomy (MIE) performed in a center with a stable and acceptable postoperative complication rate.
Background: A recent multicenter, international randomized controlled trial showed that DOF following a MIE is comparable to standard of care (nil-by-mouth). However, the effect of DOF was potentially influenced by postoperative complications.
Methods: Patients in this single-center prospective cohort study received either DOF (intervention) or nil-by-mouth for 5 days postoperative and tube feeding (standard of care, control group) following a MIE with intrathoracic anastomosis. Primary outcome was time to functional recovery and length of hospital stay. Secondary outcomes included anastomotic leakage, pneumonia, and other surgical complications.
Results: Baseline characteristics were similar in the intervention (n = 85) and control (n = 111) group. Median time to functional recovery was 7 and 9 days in the intervention and control group (P < 0.001), respectively. Length of hospital stay was 8 versus 10 days (P < 0.001), respectively. Thirty-day postoperative complication rate was significantly reduced in the intervention group (57.6% vs 73.0%, P = 0.024). Chyle leakage only occurred in the control group (18.9%, P < 0.001). Anastomotic leakage, pneumonia, and other postoperative complications did not differ between groups.
Conclusion: Direct oral feeding following a MIE results in a faster time to functional recovery and lower 30-day postoperative complication rate compared to patients that were orally fasted.
