We read with enormous interest the study by Kamal et al.1 For the past two decades, dispute on the carcinogenic effects of PPI has remained. In this retrospective study using nationwide registries, long-term use of PPIs was identified to be associated with increased risks of gallbladder, intrahepatic and extrahepatic bile duct cancers. This study is the first large-scale population-based study assessing biliary tract cancer risks under PPI use, using high-quality data and well-designed methods. ...

Randomized control trials and meta-analyses comparing colonoscopies with and without computer-aided detection (CADe) assistance showed significant increases in adenoma detection rates (ADRs) with CADe. A major limitation of CADe is its false positives (FPs), ranked 3rd in importance among 59 research questions in a modified Delphi consensus review. The definition of FPs varies. One commonly used definition defines an FP as an activation of the CADe system, irrespective of the number of frames or...

Background and Aims Since 2008, a plethora of research studies has compared the efficacy of water-assisted (aided) colonoscopy (WAC) and underwater resection (UWR) of colorectal lesions with standard colonoscopy. We reviewed and graded the research evidence with potential clinical application. We conducted a modified Delphi consensus among experienced colonoscopists on definitions and practice of water immersion (WI), water exchange (WE), and UWR. Methods Major databases were searched to obtain ...
