- Abstract
Abstract Gastrointestinal (GI) motility dysfunction is a common complication of any abdominal surgical procedure. During fasting, the upper GI tract undergoes a cyclic change in motor activity, called the interdigestive migrating motor contraction (IMC). The IMC is divided into four phases, with phase III having the most characteristic activity. After digestive surgery, GI motility dysfunction shows a lack of a fed response, less phase II activity, more frequent phase III activity of the IMC, and some phase III activity migrating orally. Postoperative symptoms have been related to motor disturbances, such as interrupted or retrograde phase III or low postprandial activity. The causes of GI disorder are autonomic nervous dysfunction and GI hormone disruptions. The administration of a motilin agonist can induce earlier phase III contractions in the stomach after pancreatoduodenectomy. For nervous dysfunction, an inhibitory sympathetic reflux is likely to be important in postoperative motility disorders. Until recently, treatment for gut dysmotility has consisted of nasogastric suction, intravenous fluids, and observation; however, more effective treatment methods are being reported. Recent discoveries have the potential to decrease postoperative gut dysmotility remarkably after surgery.
