Percutaneous Peritoneal Dialysis Catheter Placement in Patients with Complex Abdomen.

Abstract

Peritoneal dialysis (PD) is an effective treatment for end-stage renal disease. There are several techniques of percutaneous PD catheter placement including trocar or Seldinger techniques. Placement can be performed with fluoroscopy and/or sonography or as a blind percutaneous procedure. Historically, percutaneous PD catheters have been placed in patients even if they had prior abdominal surgeries. The outcomes of percutaneous PD catheter placement in patients with complex abdomen (patients with two or more abdominal surgeries or known adhesions) are unknown. This study was carried out to determine the outcomes of percutaneous PD catheter placements using Seldinger technique with sonography and fluoroscopy in patients with complex abdomen. Preprocedure sonography was also used to identify site of adhesions and blood vessels. The goal was to see if ultrasound and fluoroscopy would support placement of PD catheters in patients with complex abdomens. There were total of 10 catheter placements in 10 patients with complex abdomen. The initial success rate was 100%. The patients had an average of 2.8 abdominal surgeries. The mean BMI was 28.4. There were no incidences of perforation or failed placements. One catheter was replaced due to outflow failure and one patient discontinued PD due to peri-catheter leak. One year catheter survival was 80%. Our study demonstrates benefits of using ultrasonography and fluoroscopy during percutaneous PD catheter placement by the Seldinger technique in patients with complex abdomen.
