Surgical management In cases involving obstructive<unk> , the primary treatment includes biliary decompression. If bile stones are present in the common bile duct, an endoscopic sphincterotomy can be conducted either with or without placing a stent. To do this, a duodenoscope is placed by the endoscopist in the second portion of the duodenum. A catheter and guidewire is moved up into the common bile duct. A sphincterotome can then enlarge the ampulla of Vater and release the stones. Later, the endoscopist can place a stent in the common bile duct to soften any remaining stones and allow for bile drainage. If needed, a balloon catheter is available to remove any leftover stones. If these stones are too large with these methods, surgical removal may be needed. Patients can also request an elective cholecystectomy to prevent future cases of choledocholithiasis. In case of narrowing of the common bile duct, a stent can be placed after dilating the constriction to resolve the obstruction. The treatment approach for patients with obstructive<unk>  resulting from cancer varies based on whether they are a suitable candidate for surgery. In most cases, surgical intervention is the best option. For patients whom complete removal of the biliary obstruction is not possible, a combination of a gastric bypass and hepaticojejunostomy can be used. This can reestablish bile flow into the small intestine, thereby bypassing the blockage. In cases where a patient is not a suitable candidate for surgery, an endoscopic stent can be placed. If this is not possible or successful, a percutaneous transhepatic cholangiogram and percutaneous biliary drainage can be used to visualize the blockage and re-establish bile flow. Medical management A significant portion of patients with<unk>  (80%) will experience pruritus at some point during their disease. This is a condition that can severely decrease a patient's quality of life as it can impact sleep, concentration, work ability, and mood. Many treatments exist, but how effective each option is depends on the patient and their condition. Assessment using a scale, such as a visual analogue scale or a 5-D itch scale will be useful to identify an appropriate treatment. Possible treatment options include antihistamines, ursodeoxycholic acid, and phenobarbital. Nalfurafine hydrochloride can also be used to treat pruritus caused by chronic liver disease and was recently approved in Japan for this purpose. Bile acid binding resins like cholestyramine are the most common treatment. Side effects of this treatment are limited and include constipation and bloating. Other commonly used treatments include rifampin, naloxone, and sertraline. In cholestatic liver disease, when bilirubin concentration starts to build up, a deficiency of fat soluble vitamins may also occur. To manage this, doses of vitamin A, D, E, and K are recommended to retain appropriate vitamin levels. Cholestatic liver disease can impact lipids, and possibly lead to dyslipidemia, which may present a risk for coronary artery disease. Statins and fibrates are generally used as lipid lowering therapy to treat patients with cholestatic liver disease. For intrahepatic<unk>  in pregnant women, S-adenosylmethionine has proven to be an effective treatment. Dexamethasone is a viable treatment in regards to the symptom of intensive itching.
