Mudireddy PR, et al. – This multicenter study investigated the technical and clinical success and adverse events of using lumen apposing metal stents (LAMSs) in the drainage of post–surgical fluid collections (PSFCs). To drain PSFCs, the use of LAMSs had a high technical and clinical success rate with low adverse events (AEs). LAMS placement was a viable alternative to repeat surgery or percutaneous drainage for collections that were favorably located adjacent to the stomach, duodenum or rectum.

• Using LAMSs, collaborators from 8 centers retrospectively reviewed their endoscopic databases to find procedures for drainage of post-surgical collections.
• They measured technical success (successful placement of LAMSs into the fluid collection), clinical success (complete resolution of the fluid collection on repeat imaging or endoscopy), and intra- and post-procedure adverse events (AEs).

• They identified 47 patients with PSFCs after various surgeries.
• 13 patients had failed previous percutaneous or surgical drainage attempts.
• Fluid collections averaged 78.6 mm (47-150 mm) in size.
• Transgastric was the most common site of stent placement, followed by rectum and duodenum.
• In this study, technical success rate was 93.6 %, and clinical success rate was 89.3%.
• The intraprocedural AE rate was 4.25% and postprocedural AE rate was 6.4 %.
• They noted 1 death unrelated to the procedure.
