<unk>  is a disorder of some component of<unk>  part of the digestive system in which bile cannot physically move in the proper direction through the tubular<unk>  tract. It most commonly involves abnormal<unk>  tract peristalsis muscular coordination within the gallbladder in response to dietary stimulation of that organ to squirt the liquid bile through the common bile duct into the duodenum. Ineffective peristaltic contraction of that structure produces postprandial (after meals) right upper abdominal pain (cholecystodynia) and almost no other problem. When the<unk>  is localized at the<unk>  outlet into the duodenum just as increased tonus of that outlet sphincter of Oddi, the backed-up bile can cause pancreatic injury with abdominal pain more toward the upper left side. In general,<unk>  is the disturbance in the coordination of peristaltic contraction of the<unk>  ducts, and/or reduction in the speed of emptying of the<unk>  tree into the duodenum.
