Patients on peritoneal dialysis (PD) may develop PD-related complications that necessitate abdominal surgery. However, when to resume PD and how to prescribe PD fluid after surgery in pediatric patients are unknown.Patients on PD who underwent small-incision abdominal surgery between May 2006 and October 2021 were included in this retrospective observational study. The complications after surgery and characteristics of patients with PD fluid leakage were analyzed.Thirty-four patients were included. They underwent 45 surgical procedures, including 23 inguinal hernia repairs, 17 PD catheter repositioning or omentectomy, and 5 others. The median time to resume PD was 1.0 (IQR, 1.0-3.0) days, and the median PD exchange volume at the initiation of PD after surgery was 25 (IQR, 20-30) ml/kg/cycle. PD-related peritonitis occurred in two patients after omentectomy and one after inguinal hernia repair. There was no PD fluid leakage or hernia recurrence among the 22 patients who had a hernia repair. Peritoneal leakage occurred in 3 of the 17 patients who had PD catheter repositioning or an omentectomy and was treated conservatively. No patients who resumed PD 3 days after small-incision abdominal surgery with less than half of PD volume had fluid leakage.Our findings demonstrated that PD could be resumed within 48 h of inguinal hernia repair with no PD fluid leakage or hernia recurrence in pediatric patients. In addition, resuming PD 3 days after a laparoscopic procedure with less than half of the usual dialysate volume might reduce the risk of PD fluid leakage.
