Objective: Enhanced recovery after surgery (ERAS) protocols are established in adults but not fully evaluated in children. This study investigated whether an ERAS protocol improved recovery and influenced postoperative inflammatory cytokine levels in children undergoing surgery for hydronephrosis.
Methods: This randomized controlled study included patients who underwent robot-assisted laparoscopic surgery for hydronephrosis at Bayi Children's Hospital (Beijing, China) between October 2018 and September 2019. Patients were randomized to an ERAS group (perioperative ERAS protocol) or control group (standard perioperative management). Outcomes related to postoperative recovery and inflammatory cytokine levels were evaluated.
Results: The final analysis included 18 patients in each group. Five patients (27.78%) in each group experienced postoperative complications (abdominal pain, nausea and vomiting, subcutaneous emphysema or fever). The ERAS group had a shorter time to first postoperative flatus than the control group (25 vs. 49 hours; P =0.009), although the time for abdominal drainage flow to reach ≤20 mL/day, time to urinary catheter removal and length of hospital stay did not differ significantly between groups. Preoperative plasma cytokine levels were comparable between groups. Compared with the control group, the ERAS group had a higher IL-6 level on postoperative day 2 ( P <0.05) and a lower concentration of IL-1β on postoperative days 1 and 2 ( P <0.05). Postoperative levels of CRP, TNFα and IL-10 did not differ significantly between groups.
Conclusions: ERAS may accelerate postoperative recovery and modulate the postoperative inflammatory response in pediatric patients undergoing robot-assisted laparoscopic pyeloplasty for hydronephrosis.
