Comparative experience of a simple technique for laparoscopic chronic ambulatory peritoneal dialysis catheter placement: comment

Malfunctioning Peritoneal Dialysis Catheter and Accompanying Surgical Pathology Repaired by Laparoscopic Surgery

♦ Objectives

To review the laparoscopic salvaging of malfunctioning peritoneal dialysis (PD) catheters, and to present our experience with laparoscopic repair of dysfunctional Tenckhoff catheters and the treatment of accompanying surgical pathologies.

♦ Design

Malfunctioning peritoneal catheters were repaired using laparoscopic rescue techniques. Accompanying surgical problems were treated in the same operation. The effectiveness of these approaches was validated by comparison with other remedial techniques described previously.

♦ Patients

Malfunctioning PD catheters were salvaged by laparoscopic surgery in 8 patients, and accompanying surgical problems were treated in the same operation in 3 of the 8 patients.

♦ Main Outcome Measures

Outcome was measured by the successful return to adequate PD and effective treatment of surgical problems.

♦ Results

Eight patient studies show laparoscopic correction of malfunctioning catheters and the treatment of accompanying surgical pathologies with the return to successful PD.

♦ Conclusion

The salvaging of malfunctioning PD catheters by laparoscopic surgery is an ideal method. This procedure permits simultaneous identification and correction of other surgical problems that could otherwise complicate dialysis therapy.

The laparoscopic option in the management of peritoneal dialysis catheter revision

BACKGROUND

Long-term functioning of peritoneal dialysis catheters (PDCs) depends on maintenance of pelvic positioning and prevention of the formation of adhesions. The purpose of this study was to evaluate the validity of laparoscopy as a tool for the correction of malfunctioning PDCs and to introduce our specially designed technique.

METHODS

The charts of 12 patients who underwent laparoscopic revisions of malfunctioning PDCs between May 1997 and June 2000 were reviewed for perioperative complications and long-term outcomes. We describe the causes of malfunction of PDCs and the laparoscopic technique for their revision.

RESULTS

Of the 12 patients studied, the malfunction of eight catheters resulted from migration of the catheter into the upper abdomen. In 4 patients, formation of adhesion of either small bowel or omentum resulted in the malfunction of the PDC. The only complication we encountered was bleeding. It occurred in 3 patients, 1 of whom needed reoperation in order to achieve hemostasis. Over a median follow-up of 21 months all PDCs treated this way are functioning.

CONCLUSIONS

The laparoscopic management of malfunctioning PDCs is a valid option for the treatment of such a complication.
