The easiest way to keep up-to-date with DAVE is via RSS.
What is RSS?
RSS, also called RSS feeds, allow you to see when websites have added new content. You can get the latest articles and video in one place, as soon as they're published, without having to visit the websites you have taken the feed from.
How do I start using RSS?
In general, the first thing you need is a RSS feed reader, software that checks feeds and notifies you of new articles. There are many different feed readers, a very popular one is Google Reader, and all modern web-browswers have feed reading capability built in (e.g. Internet Explorer 7+, Firefox 2+, and Safari 2+). Once you have chosen a RSS reader, all you have to do is to decide what content you want it to subscribe to.

Peroral transhepatic cholangioscopy and lithotripsy after biliopancreatic diversion
Manuel Perez-Miranda, MD : 03 May 2010
Biliopancreatic diversion is a morbid obesity surgery in which a long afferent loop is anastomosed to the ileum. It makes peroral ERCP impossible. Intraoperative ERCP through the distal antrum is feasible, and convenient if cholecystectomy is needed. A 72 y.o. female had prior cholecystectomy and biliopancreatic diversion with gastrectomy.

Gastric endoscopic submucosal dissection (ESD) with a new traction method: the Clip-band technique
Adolfo Parra-Bianco, MD, PhD : 03 May 2010

Duplication cyst of the duodenum
Harry Aslanian, M.D. : 15 Apr 2010
A 50 year old male with chief complaint of post-prandial vague abdominal pain had a capsule endoscopy exam, which showed submucosal mass in the proximal small bowel.
