Anastomosis is the medical term for a surgical connection between two tubular structures, channels, or passages that typically do not attach. In medical terminology, anastomosis is when surgeons connect two tube-like structures inside the body. This article looks at the types of anastomosis and their uses. It also outlines what to expect during and after anastomosis. Anastomosis occurs naturally in the body, where veins and arteries connect to transport blood around the body. In the vascular system, it creates a backup pathway for blood flow if something blocks a blood vessel. Vascular fistulae are abnormal anastomoses, where blood vessels join together through injury, inflammation, or disease.

Anastomosis

Such a connection may be normal such as the foramen ovale in a fetus' heart or abnormal such as the patent foramen ovale in an adult's heart ; it may be acquired such as an arteriovenous fistula or innate such as the arteriovenous shunt of a metarteriole ; and it may be natural such as the aforementioned examples or artificial such as a surgical anastomosis. The reestablishment of an anastomosis that had become blocked is called a reanastomosis. Anastomoses that are abnormal, whether congenital or acquired, are often called fistulas. The term is used in medicine , [1] biology , mycology , geology , and geography. An anastomosis is the connection of two normally divergent structures. The circulatory anastomosis is further divided into arterial and venous anastomosis. Arterial anastomosis includes actual arterial anastomosis e. Anastomoses also form alternative routes around capillary beds in areas that do not need a large blood supply, thus helping regulate systemic blood flow. Surgical anastomosis occurs when segments of intestine , blood vessel, or any other structure are connected together surgically anastomosed. Examples include arterial anastomosis in bypass surgery , intestinal anastomosis after a piece of intestine has been resected, Roux-en-Y anastomosis and ureteroureterostomy. Pathological anastomosis results from trauma or disease and may involve veins , arteries , or intestines.

In evolution anastomosis, anastomosis is a recombination of evolutionary lineage. In geologyveins of quartz or other minerals can display anastomosis. Play Play.

Anastomosis is the connection of two things that are normally diverging. In medicine, an anastomosis typically refers to a connection between blood vessels or between two loops of the intestine. Naturally occurring anastomosis refers to how structures are connected biologically in the body. For example, many veins and arteries are connected to each other. This helps us efficiently transport blood and nutrients throughout the body. A surgical anastomosis is an artificial connection made by a surgeon.

An anastomosis is a surgical connection between two structures. It usually means a connection that is created between tubular structures, such as blood vessels or loops of intestine. For example, when part of an intestine is surgically removed, the two remaining ends are sewn or stapled together anastomosed. The procedure is known as an intestinal anastomosis. The stomach connects the esophagus to the small intestine, and functions to break up food into small particles that can be absorbed by the small intestine. In cases of chronic stomach problems such as ulcers , obesity or cancer, partial or total removal of the stomach may be indicated. In the procedure, the diseased portion of the stomach is removed and the small intestine is attached to the remainder of the stomach to maintain the integrity of the digestive tract. The patient will be on nasogastric tube suction to keep the stomach empty and at rest after surgery. After several days, and when the stomach starts to function normally again, the tube will be removed and the patient will begin ingesting clear liquids and gradually progress to a full and normal diet. In all cases of intestinal obstruction, the intestine involved is carefully examined.
