Does Laparoscopic Omentectomy Reduce CAPD Catheter Malfunction: A Three-arm Pilot Randomized Trial.

Area of Science:

• Nephrology
• Surgical Innovation
• Medical Device Complications

Background:

• Catheter malfunction due to omental wrapping is a common issue in continuous ambulatory peritoneal dialysis (CAPD).
• Open surgical insertion is the standard method for peritoneal dialysis catheter insertion (PDCI), with laparoscopic omentectomy used as a salvage procedure.
• There is a lack of randomized controlled trials (RCTs) evaluating prophylactic laparoscopic omentectomy for CAPD catheter function.

Purpose of the Study:

• To assess the impact of prophylactic laparoscopic omentectomy on the incidence of peritoneal dialysis catheter malfunction.
• To compare catheter function following laparoscopic PDCI with omentectomy, laparoscopic PDCI without omentectomy, and open surgical PDCI.

Main Methods:

• A pilot randomized controlled trial (RCT) involving consecutive patients undergoing PDCI.
• Patients were randomized into three groups: laparoscopic PDCI with omentectomy (Group A), laparoscopic PDCI without omentectomy (Group B), and open surgical PDCI (Group C).
• The primary outcome measured was the incidence of catheter malfunction at 6 weeks and 3 months post-insertion.

Main Results:

• Catheter malfunction rates at 3 months were 6.2% (Group A), 36.4% (Group B), and 21.4% (Group C).
• In patients with a history of failed catheter insertion, omentectomy was associated with a significantly lower malfunction rate at 3 months (8.3% vs. 45.5%, P=0.069).
• Operating time was significantly longer in the laparoscopic omentectomy group (Group A).

Conclusions:

• Laparoscopic omentectomy may reduce the incidence of peritoneal dialysis catheter malfunction, especially in patients with prior catheter failure.
• This pilot RCT provides valuable data for designing larger trials to confirm these findings.
• Further research is warranted to optimize surgical techniques for PDCI and minimize catheter-related complications.
