[How to manage abdominal hernia on peritoneal dialysis?]

Abdominal hernias are a frequent complication in peritoneal dialysis, representing up to 60.4% of anatomical complications. Their prevalence varies between 7 and 27.5%. Established risk factors are male gender, an older age, multiparity, a low body mass index and a paramedian approach for the catheter insertion. Polykystic renal disease and the intra-peritoneal volume are controversial risk factors. The diagnosis is mainly clinical, though peritoneography imaging can be useful in difficult cases. Hernia's complications, of strangulation, incarceration, bowel occlusion and peritonitis; can be very serious, leading to technique failure and may result in death. The complication risk varies from 4 to 20% in the literature review. There are no guidelines regarding hernia's prevention or treatment. A surgical repair is recommended, by implementing a synthetic prothesis with an inguinal approach for inguinal and femoral hernias, with a simple stitch or a bioprothesis for ombilical hernias. The management of peritoneal dialysis after hernia repair is not codified. After an initial 48h interruption, an intermittent peritoneal dialysis program using low volume seems efficient at low risk, preventing a temporary transfer to haemodialysis.
