Multicenter randomized trial comparing diagnostic sensitivity and cellular abundance with aggressive versus standard biliary brushing for bile duct stenosis without mass syndrome

Karsenti David et al.

The diagnosis of cholangiocarcinoma in patients with a biliary stricture without mass syndrome can be obtained by biliary brushing with a sensitivity of ~50 %. The authors performed a multicenter randomized crossover trial comparing the aggressive Infinity brush with the standard RX Cytology Brush. The aims were to compare sensitivity for cholangiocarcinoma diagnosis and cellularity obtained. 

High quality colonoscopy: using textbook process as a composite quality measure

Nass Karlijn J et al.

High quality colonoscopy is fundamental to good patient outcomes. “Textbook outcome” has proven to be a feasible multidimensional measure for quality assurance between surgical centers. In this study, Nass et al sought to establish the “textbook process” (TP) as a new composite measure for the optimal colonoscopy process and assessed how frequently TP was attained in clinical practice and the variation in TP between endoscopists.

Mandatory vs. optional split-dose bowel preparation for morning colonoscopies: a pragmatic noninferiority randomized controlled trial

Dolovich Casandra et al.

Multiple devices are available for tissue approximation. A new through-the-scope suturing (TTSS) device has recently been introduced; however, data on its scope of use and clinical effectiveness are limited. Krishnan et al. aimed to assess the clinical course and effectiveness of this TTSS device.
