Welcome to The SAGES Surgical WIKI

SAGES launched its member-generated Wiki in 2010 and it quickly grew into a resource accessed by more than 2,500 people/month seeking advanced and accurate definitions of all types of minimally invasive surgery and diseases treated by minimally invasive surgery.

As part of the recent overhaul to SAGES web properties, the SAGES Wiki has been moved to a new home on the SAGES site. In addition to moving more than 75 member-generated articles back to the main SAGES web site, we have also completely changed the way members can interact with the Wiki:

  • It’s easier than ever to become a contributor! Simply log in with your member account and head over the Wiki pages. Use the “Create A New Wiki” button on the right sidebar to add your own article.
  • If you see a way to improve an existing article, simply click the Edit tab at the top of the article and make your edits.
  • Want to discuss an article? All logged-in SAGES members can now comment on an article using the Discussion tab at the top of the article and post away.

Idiopathic achalasia, found in the northern America closely mimics “Chagas Disease of the esophagus” occurring in South America.   Pathophysiology Anatomic alterations Abnormalities in all neuromuscular components of the esophagus and its central nervous connection have been described but a pathogonomic defect remains elusive.
