Anastomosis

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.

Gastrectomy

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.

Before and after small intestine anastomosis

In all cases of intestinal obstruction, the intestine involved is carefully examined. If any parts of the intestine look unhealthy from lack of blood flow during the period of obstruction, they are removed and the healthy ends are reconnected. A patients recovery depends on the cause of the intestinal obstruction and the length of time prior to relief of the obstruction. The outcome is usually good if the obstruction is treated before damage (ischemia) or death (necrosis) of the bowel occurs.
