270 EUS Guided Drainage of Peripancreatic Fluid Collections and Necroses Using a Novel Lumen-Apposing Stent: a Large Multicenter U.S. Experience

and the clinical success rates were similar (93.1% and 100%, P Z 0.119). When comparing EGBD with PC, significantly more patients in PC group suffered from adverse events (25.9% vs 70.7%, P! 0.001) and required more frequent unplanned admissions (6.9% vs 70.7%, P! 0.001). The most common causes of readmission in the PC group were due to tube dislodgement and blockade. The 30-day adverse event rates were similar between the groups (29.3% vs 15.5%, P Z 0.118). The rates of recurrent acute cholecystitis were low in both groups (0% vs 3.4%, PZ 0.244) and no difference in overall mortality was observed (P Z 0.115). Conclusion: EGBD and PC were both effective means of obtaining gallbladder drainage. In the absence of percutaneous tubing, EGBD reduced the overall morbidities and number of unplanned admissions while the 30-day adverse event rates were similar. Thus, EGBD may potentially replace PC as the treatment of choice in patients that are unfit for surgery. Table 1. Comparison in background demographics between the groups www.giejournal.org EGBD
