[Diagnosis and therapy of exit-site infection in peritoneal dialysis: an update].

Exit-site infection (ESI) is still one of the most important technical complications in peritoneal dialysis because it can lead to peritonitis and catheter loss. Catheter choice does not appear to affect exit-site infection in most cases. Early diagnosis is extremely important in reducing such complications. Ultrasound inspection of the exit site and of the subcutaneous tunnel is one of the best practices to prevent technique failure. Surgical technique, peri- and postoperative protocols and care of the exit site are key points. Medical therapy should be selected based on international guidelines and prompt and timely intervention is the basis of successful therapy. A new treatment for exit-site infection is described and discussed in this paper.
