“…As prophylaxis for migration, catheters that are weighted or utilize a swan neck design can be used; studies suggest better long‐term results with these methods of treatment . Some authors recommend catheter placement with an additional suture from the inside of the peritoneum when catheter is inserted.…”

This report reviews the most common surgical interventions and complications of chronic peritoneal dialysis (PD) patients. Based on the current knowledge as well as our experience we detail the role of these surgical procedures. We supplement the reported knowledge in the field with our own experience in this area. The areas discussed include early complications such as surgical wound hemorrhage, bleeding from the catheter, intestinal perforation and urinary bladder perforation, dialysate leakage through the wound, as well as late complications including catheter kinking or occlusion, retention of fluid in the peritoneal recess, hernias and hydrothorax, and encapsulating peritoneal sclerosis. We also briefly cover the surgical aspects of exit-site infection and peritonitis. An understanding by nephrologists of the role for surgical intervention in PD patients will improve their care and outcomes.

“…The weight of the tip (12 g) is intended to prevent catheter displacement when floating in the peritoneal fluid or as a result of bowel loop movement. Although the incidence of malfunction with SLCs is lower when compared to other types of catheters, (14,(16)(17)(18)(19)(20)(21)(22)(23), current prospective studies are limited and there is no record of randomized studies.…”

“…Multiple studies have shown improved function, decreased migration, and longer catheter survival with the SLPDC. [9][10][11][12][13][14] However, drawbacks of the SLPDC include the signi cantly increased diameter of the terminal tungsten cylinder compared to the nominal diameter of the catheter precluding the ability to place it percutaneously through small sheaths, its inability to vary the length of the effective catheter, and its restricted application to a straight catheter instead of a coiled catheter.…”

Purpose Peritoneal dialysis (PD) catheters function best when residing within the retrovesical space of the peritoneal cavity, but they frequently migrate and fail. A novel variable length and conforming PD catheter weighted anchor to prevent migration has been evaluated.Methods Test devices were placed in normal saline for 21 months. The effluent was periodically measured for heavy metals, including tungsten. The water-tight property of the device was also tested separately. Four cadavers were subjected to three-dimensional imaging and maneuvering to evaluate percutaneous insertion, function, stability within the retrovesical space, and percutaneous retrievability in 10 test devices.Results Liquid leakage was low, with a mean absorbance of the test device effluent saline of 0.015. Mean methylene blue absorbance of the test device was significantly lower than the positive control (p-value = 0.01). Leakage of tungsten from devices made with medical grade Silastic tubing was also low, with a mean of 0.362 mg/L in the effluent saline, compared to a background concentration of 0.166 mg/L. Each test device was successfully inserted into the retrovesical space and retrieved percutaneously and remained completely intact following placement and insertion. No test device migrated as shown on axial cone beam CT imaging. Mean flow times and volumes were satisfactory at 3 minutes and 0.92L, respectively, for all test devices. For all catheters, the mean flow rate was 312 cc/min. No significant difference was found between the pre-roll and post-roll mean flow rates of the test devices (p-value = 0.35).Conclusion This PD catheter weighted anchor showed stability, with minimal leakage of tungsten. All test devices were successfully inserted and retrieved percutaneously, with no damage or migration, and mean flow rates were satisfactory. Further investigation is warranted.
