Long-term intraperitoneal access with description of a new access catheter.

BACKGROUND AND OBJECTIVES

Intraperitoneal chemotherapy can be administered as a single dose associated with hyperthermia (HIPEC) or in successive doses under normothermic conditions, such as early postoperative intraperitoneal chemotherapy (EPIC) or normothermic intraperitoneal chemotherapy (NIPEC or NIPEC-LT). Repetitive administration of intraperitoneal chemotherapy over a prolonged period may be associated with catheter-related complications, which are the primary cause of treatment interruption. This study aims to introduce and evaluate an innovative catheter system designed to mitigate these issues.

METHODS

Using a porcine experimental model, we tested a new catheter for long-term intraperitoneal access. Sixteen animals underwent catheter implantation followed by normothermic recirculation of peritoneal dialysis solution. Catheter functionality and any complications were monitored throughout successive treatment cycles.

RESULTS

The new catheter system demonstrated optimal recirculation and maintained its functionality throughout successive treatments, without complications. Catheter replacement with a guidewire was successful, ensuring continued efficacy.

CONCLUSIONS

The innovative catheter system shows promise in reducing complications and improving compliance in successive intraperitoneal chemotherapy doses, justifying further clinical trials to confirm its efficacy in patients.
