Abstract
INTRODUCTION: This study describes a new preperitoneal tunneling (PPT) method for inserting a peritoneal dialysis catheter (PDC), thereby lessening surgical complications and increasing the catheter's survival. METHODS: This new technique was used in 23 cases from December 2005 to January 2007 and followed up until March 2011 (63 months). The procedure was performed laparoscopically under local (16 cases) or general (7 cases) anesthesia by one surgeon. Catheter survival is reported by Kaplan-Meyer analysis. RESULTS: The catheters were mechanically obstructed in 2/23 cases (8.7%); and were withdrawn due to a peritonitis in 2 cases and inadequacy of peritoneal dialysis in 1 case. Ten patients received kidney transplantation and six died before completing this follow-up period. The patients still reaped the benefits of the PDC until receiving a kidney transplant or death. The 5-year survival rate of the catheter was 89%. No incidence of catheter migration, omental wrapping, herniation or leakage was noticed. CONCLUSION: Preperitoneal tunneling is a simple and safe method for insertion of PDC, and can effectively prevent catheter migration, dislocation and omental wrapping.
