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.

Recommended Wiki: Pyloric Stenosis

Introduction Hypertrophic Pyloric Stenosis (HPS) is due to concentric hypertrophy of the pyloric smooth muscle, leading to gastric outflow obstruction and has an incidence of .1-.4%, with most cases occurring in Caucasians. At a ratio of 4:1, boys are more likely to be affected than girls, with first born male children having a higher susceptibility to the condition. HPS has been found to occur in 20% of male offspring and 10% of female offspring to a mother with pyloric stenosis herself. An increased incidence of HPS has been linked to infants with B and O blood groups, and there is a higher concordance of HPS in monozygotic than dizygotic twins, suggesting a genetically based predisposition. Its occurrence has been linked to macrolide use during pregnancy and erythromycin (a motilin agonist) administration in neonates, with risk increasing by a factor of 8 if administered during days 3-13 of the newborn's life.… Continue Reading »
