Encyclopedia > Surgical anastomosis

In surgical jargon, to create an anastomosis is to stitch together two cut ends of any hollow organ, usually to restore continuity after resection, or to bypass an unresectable disease process. An anastomosis (plural anastomoses) refers to a form of network in which streams both branch out and reconnect. ...

Anastomosis are typically performed on:

  • Gastrointestinal (GI) tract: Esophagus, stomach, small bowel, large bowel, bile ducts, and pancreas. Virtually all elective resections of gastrointestinal organs are followed by anastomoses to restore continuity; pancreaticoduodenectomy is considered a massive operation, in part, because it requires three separate anastomoses (stomach, biliary tract and pancreas to small bowel). Bypass operations on the GI tract, once rarely performed, are the cornerstone of bariatric surgery. The widespread use of mechanical suturing devices (linear and circular staplers) changed the face of gastrointestinal surgery.
  • Microsurgery: The advent of microsurgical technique allowed anastomoses previously thought impossible, such as so-called "nerve anastomoses" (not strictly an anastomosis according to the above definition), and operations to restore fertility after tubal ligation or vasectomy.

Fashioning an anstomosis is typically a complex and time-consuming step in a surgical operation, but almost always crucial to the outcome of the procedure.
