A.

The newest experimental treatment for gastroparesis is injection of botulinum toxin into the pylorus. The pylorus is the narrow channel through which food passes from the stomach to the duodenum. The pylorus, like the stomach, is a muscular organ. The pylorus is closed most of the time due to continuous contraction of the pyloric muscle. Intermittently it opens and allows secretions from the stomach to enter the small intestine. After meals, the pylorus is very important for metering the emptying of the stomach. In gastroparesis, although the muscles of the stomach are weak all of the time, the muscle of the pylorus remains strong and contracted and the pylorus relatively closed. It was hypothesized that if the strength of the pyloric muscle was reduced, food might empty from the stomach more readily. Although a surgical procedure, termed pyloroplasty, to enlarge the pylorus has been used in the past to treat problems with emptying of the stomach, it is major surgery and has had mixed results with respect to its efficacy. More recently, relaxation of the pyloric muscles has been produced by injecting botulinum toxin (Botox) into the pylorus. Although results have been good, the procedure has not been studied enough to recommend its use unless it is part of a research protocol.
