Prevalence and management of hernias in peritoneal dialysis patients.

Objectives: The aim of this study was to assess the prevalence of hernias before and after the start of continuous ambulatory peritoneal dialysis (CAPD) in patients with end-stage renal disease, and to evaluate the result of a proposed surgical treatment.

Design: Prospective observational study.

Setting: University hospital.

Patients: 122 patients who started CAPD from 1994 to 2000; 26 hernias were diagnosed in 21 (17.2%) patients.

Main Outcome Measures: Finding of hernias; morbidity associated with catheter insertion and hernia repair; recurrence of hernias.

Results: 19 hernias were detected in 15 patients (12.3%) before they began CAPD; only 7 hernias were observed while on CAPD. Umbilical (61.5%) and inguinal (26.9%) hernias were the most common. Multiple hernias were detected in 4 patients. Simultaneous repair of hernia and catheter insertion was performed in patients with pre-existing hernias. Under local anesthesia, most patients were operated on with surgical techniques of tension-free hernioplasty using a polypropylene mesh. Only mild post-operative complications were recorded: 3 seromas and 1 hematoma. No fluid leakage was found in our series. There were no long-term complications (infection or recurrence) related to the mesh.

Conclusions: 73% of hernias in peritoneal dialysis patients occur before starting dialysis. Hernia problems in these high-risk patients can be safely solved using a careful technique with application of tension-free hernioplasty. Most may be repaired under local anesthesia with simultaneous catheter insertion.
