Percutaneous Catheter Drainage

Q: Is percutaneous drainage painful?

The procedure is performed under local anaesthesia and is generally well tolerated. Patients may feel pressure as the catheter is advanced. Sedation can be added for anxious patients.

Q: How long does the drainage catheter stay in?

The catheter remains in place until the collection has resolved — typically 5–14 days for simple fluid collections and several weeks for infected pancreatic necrosis.

Q: When is percutaneous drainage not enough and surgery is needed?

PCD may be insufficient when the collection contains thick solid necrotic debris that cannot be evacuated through a catheter, or when multiple non-communicating loculations prevent complete drainage.

Image-guided insertion of a drainage catheter through the skin — minimally invasive first-line intervention for pancreatic and intra-abdominal collections.

What is Percutaneous Catheter Drainage?

Percutaneous catheter drainage (PCD) is a minimally invasive procedure in which a drainage catheter is inserted through the skin into a fluid collection under real-time CT or ultrasound guidance. It allows continuous external drainage of pus, infected fluid, or enzymatic pancreatic secretions without the need for open surgery. Dr. Tagore Mohan Grandhi employs percutaneous catheter drainage as the preferred first-step intervention in the step-up approach to infected pancreatic necrosis and other intra-abdominal collections. By achieving source control with minimal physiological insult, PCD allows critically ill patients to stabilise before any further intervention.

Suitable for patients with symptomatic pancreatic pseudocysts, infected peripancreatic fluid collections, walled-off pancreatic necrosis, liver abscesses, and intra-abdominal abscesses from any cause.

How the Procedure Works

Pre-procedure Assessment

CT abdomen with contrast defines the collection's size, location, contents, and relationship to adjacent vessels and bowel. Coagulation profile and renal function checked.

Image-Guided Planning

The radiologist maps the safest access route to the collection on CT or ultrasound, avoiding bowel, major vessels, and the pleural cavity.

Local Anaesthesia and Needle Access

Skin and subcutaneous tissues infiltrated with local anaesthetic. Access needle advanced along the planned trajectory into the collection under real-time guidance.

Catheter Placement

Guidewire passed through the needle into the collection (Seldinger technique). Tract dilated and an 8–14 French pigtail catheter advanced and positioned. Catheter secured to the skin.

Drainage and Monitoring

Catheter connected to drainage bag. Output recorded daily. Catheter irrigated with saline. CT or ultrasound at 48–72 hours confirms cavity reduction. Catheter removed once output falls below 10–20 mL/day.

Who Needs This Treatment?

→Performed under local anaesthesia — suitable for critically ill and physiologically compromised patients
→Minimally invasive step-up approach — controls sepsis without the morbidity of open surgery
→Real-time image guidance ensures precise, safe catheter placement
→Definitive treatment for many collections — over 80% of pancreatic pseudocysts resolve with PCD alone

Percutaneous catheter drainage is the cornerstone of the step-up strategy for infected pancreatic necrosis and intra-abdominal collections — controlling sepsis with minimal physiological stress and, in many patients, avoiding surgery altogether.
