Post Surgical Gastric Dysmotility Syndromes
After gastric surgery, there are three major problems; slow gastric emptying (atony), rapid gastric emptying (dumping), and bile reflux. In the normal stomach, gastric motor activity and emptying are regulated such that the stomach mixes food and propels this into the duodenum at an optimal rate for digestion and absorption. Disruption of this function by surgery may lead to a variety of disorders. Operations such as vagotomy, gastric resection or gastroenterostomy can cause dumping, small gastric remnant syndrome, postvagotomy diarrhea, chronic gastric atony, reflux gastritis and Roux stasis syndrome. Each of these problems will be discussed.
