(1) Any opening between two normally separate spaces, lumina or organs, regardless of the manner—surgical, traumatic or pathological—in which the opening was created.
(2) The surgical connection between two tubular structures (e.g., end-to-end anastomosis of the colon or rectum) after a cancerous segment has been excised, or end-to-side anastomosis of a saphenous vein during a CABG.

Anastomosis

Surgical re-connection of the ends of the bowel after removal of a portion of the bowel.

anastomosis 

A natural communication between two blood vessels or other tubular structures. Example: the long posterior ciliary artery divides into two branches as it enters the posterior part of the ciliary muscle and at its anterior end these branches anastomose with each other and with the anterior ciliary arteries to form the major arterial circle of the iris. See major arterial circle of the iris.
