Postoperative management and complications after abdominal surgery in children receiving peritoneal dialysis.

Background : 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. Methods: 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. Results: 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. Conclusions: 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. [ABSTRACT FROM AUTHOR]
