A two-center comparative study of plastic and lumen-apposing large diameter self-expandable metallic stents in endoscopic ultrasound-guided drainage of pancreatic fluid collections.

Background And Objectives: Endoscopic ultrasound-guided drainage of walled-off pancreatic fluid collections (PFCs) (pseudocyst [PC]; walled-off necrosis [WON]) utilizes double pigtail plastic stents (PS) and the newer large diameter fully covered self-expandable stents (FCSEMS) customized for PFC drainage. This study examined the impact of type of stent on clinical outcomes and costs.

Patients And Methods: Retrospective two-center study.

The Secondary Quality Indicator to Improve Prediction of Adenoma Miss Rate Apart from Adenoma Detection Rate.

Objectives: Adenoma detection rate (ADR) cannot distinguish between endoscopists who detect one adenoma and those who detect ≥2 adenomas. Hypothetically, adenoma miss rate (AMR) may be significant for endoscopists with high ADRs who examine the rest of colon with less care after detecting first polyp. Our objective was to evaluate other quality indicators plus ADR vs.
