A surgical anastomosis is the joining of two body structures that are not currently connected. It’s performed during surgery and may be done to repair a defect, to make the anatomy functional again after tissue is removed, or to make treatment possible.

Examples
An example of treating a vascular defect would be repairing a blood vessel problem that interferes with the way blood flows to the heart muscle. In this case, acardiothoracic surgeonwould perform a procedure that would join different blood vessels together to allow blood to flow better.
Another example of an anastomosis would be after a partialcolon resection. If a portion of the intestine becomes diseased, it may need to be surgically removed in order to allow the patient to better digest their food and to decrease pain.In this example, a large section of intestine is removed—imagine a three-foot piece of string and cutting out a foot of the length out of the middle—and the remaining ends must be reconnected. The anastomosis part of the procedure would bejoining the two piecesof healthy tissue on either side of the resection, creating a newly shortened length of intestine for food and stool to pass through.
Anarteriovenous fistula, created fordialysis, is an example of a type of surgical anastomosis. For this procedure, a vein and an artery are spliced together, creating a larger blood vessel. This large vessel, when healed, can be used to insert the large dialysis catheter that is used to perform routine hemodialysis.
