Pararectal skin incision of about 6 cm inferior to the line connecting the umbilicus with the marked catheter exit. Divide the subcutaneous tissue by electrosurgery and expose the anterior lamina of the rectus sheath.

Incise the anterior lamina of the rectus sheath in a sagittal direction and dissect the rectus muscle in blunt fashion. Open the peritoneum superior to the arcuate line and preplace a peritoneal suture (PDS 3/0) at the inferior pole of the incision.
Tip:
- For better stability, the catheter should be inserted superior to the arcuate line.
- Use a monofilament suture when closing the peritoneum and anchoring the catheter because this helps avoid suture hole laceration.

Insert the CAPD catheter into the Douglas pouch with dressing forceps. When closing the peritoneum subsequently with a running suture (PDS 3-0), the latter incorporates the catheter such that the intra-abdominal silicone bead of the catheter adheres to the peritoneum, while the extraperitoneal felt plate rests anterior to the posterior lamina of the rectus sheath. This ensures secure catheter fixation and “watertight” closure of the peritoneum.
