Three-dimensional US volume analysis of gastric pseudotumors in a porcine model.
Tumor burden is difficult to estimate by endoscopy and conventional EUS. ⋯ In conclusion, the new Olympus EUS EXERA EU-M60 3D US probe allowed for accurate volume measurements of small pseudotumors in porcine stomach model in vitro. There was substantial evaluator agreement, with a low interobserver variability. Larger pseudotumors were measured with a slightly lower percentage error than smaller pseudotumors. Volumes measured with a greater number of radial images were measured slightly more accurately. We plan to test this device in patients with GI tumors in the near future.

Can U.S. GI fellowship programs meet American Society for Gastrointestinal Endoscopy recommendations for training in EUS? A survey of U.S. GI fellowship program directors.
American Society for Gastrointestinal Endoscopy (ASGE) EUS training and credentialing guidelines exist, but the capability of U.S. GI fellowships to meet these guidelines has not been assessed. ⋯ The majority of U.S. GI fellowship programs have established the EUS volume to train at least 1 EUS fellow, per ASGE guidelines; however, most 3-year and many advanced fellows are currently receiving insufficient EUS training.

Randomized Controlled Trial Comparative StudyCovered metal versus plastic stents for malignant common bile duct stenosis: a prospective, randomized, controlled trial.
Most patients with malignant common bile duct strictures are suited only for palliation of jaundice by placement of a polyethylene (PE) stent using an endoscopic retrograde cholangiographic technique. Occlusion of these stents occurs after 3 to 4 months, whereas uncovered self-expanding metal stents (SEMS) remain open twice as long. The initial higher cost of the latter might be balanced by a decreased need for repeat intervention. ⋯ The more-effective SEMS are recommended in unresectable patients with malignant common bile duct strictures, who survive a median of 4.5 months. Less costly plastic stents are preferable in the one third of patients who have distant metastases. In our study, the cost was equal.
