The effect of quality of segmental bowel preparation on adenoma detection rate.

Background: The effectiveness in surveillance colonoscopy largely depends on the quality of bowel preparation. We aimed to investigate the quality of bowel preparation segmentally and its effect on Adenoma Detection Rate (ADR) and Advanced Adenoma Detection Rate (AADR) at corresponding bowel segments.

Methods: This is a single-centered and cross-sectional study.

A Simple, Time-Saving Dye Staining of Proteins in Sodium Dodecyl Sulfate-Polyacrylamide Gel Using Coomassie Blue.

Most traditional post-electrophoretic processes need several hours to several days to finish the whole staining process and traditional staining solutions all contain methanol, acetic acid, or phosphoric acid, which not only produce the unpleasant smell but also cause environmental pollution. Here a fixation-free, fast protein staining method in sodium dodecyl sulfate-polyacrylamide gel electrophoresis using Coomassie blue is described. The protocol includes only staining and quick washing steps, can be completed in 0.

Efficacy and safety of using premedication with simethicone/Pronase during upper gastrointestinal endoscopy examination with sedation: A single center, prospective, single blinded, randomized controlled trial.

Background And Aim: To investigate the efficacy and safety of premedication with simethicone/Pronase during esophagogastroduodenoscopy (EGD) with sedation.

Methods: Six hundred and ten patients were randomly allocated to two groups based on type of premedication given. Premedication used in the control group was 10 mL lidocaine hydrochloride mucilage (LHM, N = 314) and premedication used in the intervention group was 80 mL simethicone/Pronase solution plus 10 mL lidocaine hydrochloride mucilage (SP/LHM, N = 296).
