anastomosis

[ə‚nas·tə′mō·səs]
(medicine)
A surgical communication made between blood vessels, for example, between the portal vein and the inferior vena cava.
An opening created by surgery, trauma, or disease between two or more normally separate spaces or organs.
(science and technology)
The union or intercommunication of parts or branches, such as blood vessels, streams, or leaf veins. Also known as inosculation.
A network of parts or branches created by the process of anastomosis.

Anastomosis

 

in animals, connections between nerves, muscles, and blood or lymphatic vessels. Anastomoses between arteries and veins, without the formation of capillary networks—that is, arteriovenous anastomoses—are of importance in regulating the blood supply of organs. In clinical practice, anastomosis is the name given to a connection between tubular organs which is artificial or has arisen as a consequence of disease. In higher plants, anastomosis is the connecting of tubular structures—for example, veins in leaves and branchings of latex vessels. In fungi, anastomosis is the connecting or concresence of two mycelium hyphae with the establishing of intercommunication between them. This occurs with an insufficiency of food and plays a role in the formation of diploid mycelium and the heterokaryon of haploid mycelium, since the cell nuclei move from one cell into another through the anastomoses.

The primary purpose of this prospective, randomized multicenter study is to evaluate and compare the outcomes of high risk colorectal or coloanal anastomoses constructed with GORE SEAMGUARD([R]) Bioabsorbable Staple Line Reinforcement for circular surgical staplers to standard non-reinforced colorectal and coloanal techniques with respect to the incidence of post-operative anastomotic leakage, anastomotic stricture and time to ileostomy closure.
19) Most biliary strictures occur at the anastomotic site and are probably caused by scarring and retraction after surgery, although the anastomoses may be involved by the same processes (such as ischemia) that lead to nonanastomotic strictures.
