An anastomosis is the connection of two luminal structures, such as an arterial anastomosis used in vascular bypass or a colonic anastomosis used to restore colonic continuity after the resection of colon cancer. A surgical anastomosis can be created using suture sewn by hand, mechanical staplers and biological glues, depending on the circumstances. While an anastomosis may be end-to-end, equally it could be performed side-to-side or end-to-side depending on the circumstances of the required reconstruction or bypass. The term reanastomosis is also used to describe a surgical reconnection usually reversing a prior surgery to disconnect an anatomical anastomosis, e.g. tubal reversal after tubal ligation.

Anastomosis are typically performed on:

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