934 Endoscopic Ultrasound-Guided Drainage of Pancreatic Fluid Collections Using AXIOS Electrocautery Enhanced Delivery System a Retrospective Experience at a Large Quaternary Care Center
The American journal of gastroenterology(2019)
Abstract
INTRODUCTION: Pancreatic fluid collections (PFC) are common complications of acute pancreatitis, surgery, or trauma. Many PFC reabsorb spontaneously but the remainder create cystic structures filled with fluid and/or with necrotic debris. Since the development of lumen apposing metal stents (LAMS) first line treatment of PFCs are with EUS guided drainage. However, despite the high technical and clinical success of the commonly used Electrocautery Enhanced AXIOS LAMS (EEAL), outcome data is still scarce. METHODS: An IRB approved, retrospective chart review, was performed on EUS-guided drainage of PFC using EEAL at a large quaternary care, teaching hospital. Specific procedural data including technical success rate, adverse events, and length of stay were collected. Descriptive statistics were then used to report outcomes. RESULTS: A total of 43 EEAL were used in the treatment of pancreatic pseudocysts (41.9%) and walled off pancreatic necrosis (65.1%). LAMS were placed successfully in 100% of procedures and required revisions in 28.6% of patients. Adverse events occurred in 16.3% of interventions: 2 bleeding events (4.7%), 3 stent migrations (7%), 1 pigtail stent occlusion (2.4%) and 1 spontaneous pancreatic fistula formation (2.4%). Only 2 patients (4.8%) required subsequent surgical resection. The average hospital stay after the procedure was 6.79 days (median of 3 days) and stents were ultimately removed on average at 24.68 days. CONCLUSION: This study demonstrated 100% technical success rate. Of the recorded adverse events after EEAL use in drainage of PFC most were subclinical and minor. Importantly, only two patients required further surgical intervention to obtain desired outcome. Furthermore, length of stay was particularly low with median hospital stay of 3 days. Ultimately, this study highlights how EEAL provides high value care by providing an efficient intervention in a cost-feasible length of time. Further ongoing prospective studies will help determine the utility of EEAL in the practice setting.
