Abstract
Background: Endoscopic management of abdominal collections includes endoscopic ultrasound (EUS)-guided transmural drainage, transpapillar via endoscopic retrograde cholangiopancreatography (ERCP), and EUS-guided simple puncture-aspiration (SPA). The latter is little reported, and there are some doubts about its real usefulness.
Objectives: The aim of this study was to assess the effectiveness of EUS-guided SPA as a first-line approach for treatment in selected abdominal collections.
Design: Retrospective observational study performed in two tertiary centers (Barcelona area).
Methods: Inclusion of all consecutive patients with abdominal collections that underwent EUS-guided SPA from July 2007 to July 2021. The decision was based on endoscopist criteria and collection characteristics. Clinical success was defined as avoidance of an additional interventional approach (endoscopic stenting, percutaneous drainage, surgery).
Results: Of 241 patients with abdominal collections treated endoscopically, 55 were included for analysis (mean age, 56 ± 12 years). Collection features: mean size 63.3 ± 24.8 mm; positive culture in 22 (40%) and pancreatic nature in 45 (81.8%). EUS-SPA was performed successfully in all cases, and clinical success was achieved in 76.3% (95% confidence interval (CI), 65.5-87.3) of cases (n-42/55). The most frequently used needle size was 19 Ga (85%). A nonsignificant trend for success was detected for noninfected collections (84.8 vs 63.6; p = 0.07) and lower size (mean ± SD; 60.2 ± 22.9 vs 73.8 ± 29 mm; p = 0.09). Two related adverse events were detected: one bleeding and one abdominal pain. Recurrence was detected in five pseudocysts after clinical success. Median follow-up was 629 days (IQR 389-877).
Conclusion: EUS-SPA of selected abdominal collections seems to be a safe and effective technique, avoiding a more aggressive strategy such as transmural stenting. EUS-SPA may be a viable alternative in collections with limited size and preferably noninfected.
