The effectiveness of image-guided percutaneous catheter drainage in the management of acute pancreatitis-associated pancreatic collections

Purpose: Acute pancreatitis is commonly complicated by the development of pancreatic collections (PCs). Symptomatic PCs warrant drainage, and the available options include percutaneous, endoscopic, and open surgical approaches. The study aimed to assess the therapeutic effectiveness and safety of image guided percutaneous catheter drainage (PCD) in the management of acute pancreatitis related PCs. Material and methods: This was a single-centre prospective study covering a 4-year study period. Acute pancreatitisrelated PCs complicated by secondary infection or those producing symptoms due to pressure effect on surrounding structures were enrolled and underwent ultrasound or computed tomography (CT)-guided PCD. The patients were followed to assess the success of PCD (defined as clinical, radiological improvement, and the avoidance of surgery) and any PCD-related complications. Results: The study included 60 patients (60% males) with a mean age of 43.1 ± 21.2 years. PCD recorded a success rate of 80% (16/20) for acute peripancreatic fluid collections (APFC) and pancreatic pseudocysts (PPs), 75% (12/16) for walled-off necrosis (WON), and 50% (12/24) for acute necrotic collections (ANCs). Post-PCD surgery (necrosectomy ± distal pancreatectomy) was needed in 50% of ANC and 25% of WON. Only 20% of APFCs/PPs patients required surgical/endoscopic treatment post-PCD. Minor procedure-related complications were seen in 4 (6.6%) patients. Conclusion: PCD is an effective, safe, and minimally invasive therapeutic modality with a good success rate in the management of infected/symptomatic PCs.
