"Self-Locating" Peritoneal Catheter Displaced Into an Inguinal Hernia

Prevalence and outcome of abdominal wall hernia in patients with end-stage renal disease on peritoneal dialysis

INTRODUCTION

We aimed to study the prevalence, risk factors, management, and outcome of hernias in end-stage renal disease (ESRD) patients on peritoneal dialysis (PD) from India.

METHODS

This was a retrospective study of ESRD-PD patients who developed hernias over 11 years.

RESULTS

Of 470 PD patients, 21 developed hernias (4.2%). Mean age of patients was 49.9 ± 15.36 years; 15 (66.66%) were males; 18 (85.71%) patients had umbilical hernia, 3 (14.28%) had inguinal hernia. Continuous ambulatory PD (CAPD) versus automated PD (APD) (OR: 11.623, 95% CI: 2.060-65.581, p = 0.005) was the independent risk factor identified. Incarcerated umbilical/inguinal hernia was managed surgically (6 [28.57%]); uncomplicated umbilical hernia (15 [71.42%]) managed conservatively (shift to (APD) [33.33%]; switch to low-volume APD [20%], switch to low-volume CAPD [46.66%]). None had postoperative hernia recurrences; 4 (19%) had PD technique failure; median PD survival was 36 (IQR 17-55) months.

CONCLUSION

Although complicated hernias in PD require surgical repair, uncomplicated umbilical hernias can be managed conservatively by switching to APD/low-volume CAPD, with good long-term PD technique survival.

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.
