The Combination of Double Pigtail Plastic Stent, Nasocystic Tube and Percutaneous Catheter in Endoscopic Ultrasound-Guided Transluminal Drainage for Peripancreatic Fluid Collection

Background: Endoscopic ultrasound-guided drainage is first-line treatment of Pancreatic fluid collection. The invention of metallic stents has provided a safer and more efficient approach route for internal drainage. But because of the high cost of metal stents, a large number of patients still choose plastic stents, which can help them from the disease with much lower cost. Patients and Methods: Between March to December in 2017, 20 patients with Peripancreatic fluid collections were prospectively enrolled to receive the double pigtail plastic stent with nasocystic tube and/or percutaneous catheter. Results: There were 20 cases of pseudocyst including 4 cases of infected pseudocyst. The causes of the PFC were mainly gallstones (60%), followed with alcohol (30%) and hyperlipoidemia (10%). Technical success was achieved in 100% of the cases. All patients were completely resolved with the evidence of CT scan and clinical evaluation. The mean time for resolution was 15±20 days. The mean follow-up was 3 months. Conclusion: The combination drainage of double pigtail plastic stent with nasocystic tube and/or percutaneous catheter of pancreatic pseudocyst is feasible and efficacious to most patients. Using a titanium clip could prevent migration occurrence. With the economic benefits of plastic stents, they are still wildly used in developing countries.
