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.

Perforation is present in 20-35% of children with increasing frequency in younger children, approaching 100% in infants. Pathophysiology: Appendicitis is thought to be due to obstruction of the appendiceal lumen with fecaliths, ingested foreign bodies, parasites, tumors, and/or lymphoid hyperplasia. This obstruction eventually leads to increased intraluminal pressure which causes lymphatic and venous congestion, impaired arterial perfusion, and finally ischemia and necrosis of the appendix leading to perforation. Typical Presentation: The child initially presents with malaise and anorexia that may quickly progress to abdominal pain and vomiting. The abdominal pain is initially unrelated to activity, colicky, and periumbilical… Continue Reading »
