An Unusual Case of Recurrent Migration of the Peritoneal Dialysis Catheter into the Inguinal Hernia Sac

We herein report the first case of a patient with recurrent migration of the peritoneal dialysis (PD) catheter into the inguinal hernia sac. A 58-year-old man suffered from end-stage renal disease due to polycystic kidney disease (PKD). A year before starting PD, a PD catheter was implanted with stepwise initiation of PD using the Moncrief-Popovich technique. He complained of drain failure and right inguinal swelling during the induction period and was diagnosed with right inguinal hernia. Further examination revealed that the PD catheter tip had migrated into the inguinal hernia sac. Although surgery was planned, the PD catheter tip spontaneously migrated back into the intra-peritoneal space. 14 months later, he noticed fill and drain failure again. Diagnosis was PD catheter dysfunction due to migration into the right inguinal hernia sac. PD was resumed without issues after repositioning of the PD catheter and repair of the inguinal hernia. Inguinal hernia is a frequent complication in PD patients, especially in those with PKD. Early diagnosis and treatment of hernia should be considered in PD patients.
