Double layered self-expanding metal stents for malignant esophageal obstruction, especially across the gastroesophageal junction

Double layered (outer uncovered an inner covered) esophageal stents were placed. Reflux esophagitis was more common in the GEJ group than in the non-GEJ group. Double-layered SEMS is a feasible and effective treatment when placed across GEJ.

Higher quality of life after metal stent placement compared with plastic stent placement for malignant extrahepatic bile duct obstruction: a randomized controlled trial

The study looked at 219 patients who were randomized to receive plastic stent or SEMS. The trial found that the SEMS stents were superior to plastic stents in terms of stent patency and stent dysfunction.

Usefulness of warm water and oil assistance in colonoscopy by trainees

The warm water method is a simple, safe, and feasible method for beginners. Oil lubrication may not be a useful method compared with conventional and warm water methods.

Cost Efficacy of Metal Stents for Palliation of Extrahepatic Bile Duct Obstruction in a Randomized Controlled Trial

We aimed to evaluate which type of stent (plastic, uncovered SEMS [uSEMS], or partially covered SEMS] remains longer than plastic stents, they are more expensive. The total costs after 1 year do not differ significantly with stents (€1042 or $1106) that cost significantly less than placement of SEMS (€73 or $2094) The main study end points were not blinded to groups that were at risk of infection.

The scratch test for identifying the lower liver edge is at least as accurate as percussion and is significantly more effective for young trainees-a randomised comparative trial

Young trainees were significantly more confident in their findings using the scratch test than percussion. The scratch test requires less training and all examiners and especially young trainees are more confident using it, say researchers. The study was published in the Journal of Reviews in Obstetrics and Gynaecology.

Strategies for training in diagnostic upper endoscopy: a prospective, randomized trial

The study looked at the development of a training strategy for a diagnostic endoscopy. 28 medical and surgical residents without endoscopic experience were enrolled. Ten sessions of simulator training were conducted for groups 1 and 3 during the 4-month program. All trainees demonstrated a significant reduction in procedure time during a simple manual skills test

Balloon catheter versus basket catheter for endoscopic bile duct stone extraction: a multicenter randomized trial

The rate of complete clearance in one endoscopic session was 97.4% using the balloon and 97.5% using a basket catheter. The balloon was superior to the basket in terms of rate of clearance, and the median times to complete clearance were the same in both groups.

Transparent cap improves patients' tolerance of colonoscopy and shortens examination time by inexperienced endoscopists

About 10% of colonoscopy procedures cannot be completed and polyps may be missed. The time to reach the cecum and the time for the whole procedure was significantly shorter in the CCF group than in the NCCF group.
