Tunneled Peritoneal Drain Placement

Background and indications

A tunneled peritoneal drain (PleurX® peritoneal type) is a subcutaneously tunneled indwelling catheter enabling intermittent ascites drainage at home by the patient or nurse. It is indicated for ascites refractory to medical treatment (diuretics) requiring frequent paracenteses (> 2-3/month), in cirrhotic patients not candidates for TIPS or at end of life, and for symptomatic malignant ascites (peritoneal carcinomatosis).

Pre-procedure assessment

Assessment includes abdominal ultrasound (ascites confirmation, path planning), coagulation panel, and overall medical context evaluation (prognosis, patient's ability to manage drain at home).

Procedure

Under local anesthesia and ultrasound guidance, a 5-10 cm subcutaneous tunnel is created. The tunneled catheter (15.5F) is inserted into the peritoneal cavity through the tunnel, with a Dacron cuff promoting tissue fixation and sealing. Ascites is partially drained (1-2 L). The patient is educated on intermittent home drainage (vacuum bottles). The procedure takes 30-45 minutes.

Results and scientific evidence

Tunneled drains significantly reduce hospital paracenteses and improve quality of life. For malignant ascites, frequent drainage (3 times/week) induces spontaneous peritoneal symphysis in 30-50% of cases, allowing drain removal. Studies show 50-70% reduction in hospitalization days compared to iterative paracenteses (Courtney et al., Clinical Medicine, 2008).

Risks and complications

Peri-catheter infection (5-10%, peritonitis: 2-5%), drain obstruction (10-15%), insertion site leak (5-10%, especially first weeks), local pain (10-20%). Home monitoring and patient education are essential.

Recovery

Same-day or next-day discharge. Home drainage 2-3 times weekly (500 mL-2 L per session depending on tolerance). Regular medical follow-up.

Practical information

The procedure is performed as an outpatient or short inpatient stay depending on the case. It is performed by an interventional radiologist, in coordination with the hepatologist or oncologist.
