The patient was a 69‒year‒old woman. Due to chronic renal failure caused by diabetic nephropathy, she underwent peritoneal dialysis (PD) catheter implantation in X‒9 and started PD 6 months later. She developed four dialysate leaks from abdominal wall scar hernias and underwent closure (simple closure； mesh technique). In late August X, drainage became poor, and CT confirmed leakage from a left abdominal wall hernia. Due to the marked possibility of improvement by closure of the site and patient’s strong desire to continue PD, the hernia sac was identified from the superficial side of the body and abdominal wall scar hernia repair was performed. To date, the patient has shown no recurrence, received stable PD, and exhibited no change in peritoneal function. In the present case of recurrent abdominal wall scar hernia due to abdominal wall fragility, the combination of PD prescription and surgical closure facilitated the long‒term continuation of PD.
