Cholecystectomy
Summary
Cholecystectomy is the surgical removal of the gallbladder. Cholecystectomy is a common treatment of symptomatic gallstones and other gallbladder conditions. In 2011, cholecystectomy was the eighth most common operating room procedure performed in hospitals in the United States. Cholecystectomy can be performed either laparoscopically, or via an open surgical technique.
The surgery is usually successful in relieving symptoms, but up to 10 percent of people may continue to experience similar symptoms after cholecystectomy, a condition called postcholecystectomy syndrome. Complications of cholecystectomy include bile duct injury, wound infection, bleeding, retained gallstones, abscess formation and stenosis (narrowing) of the bile duct.
Pain and complications caused by gallstones are the most common reasons for removal of the gallbladder. The gallbladder can also be removed in order to treat biliary dyskinesia or gallbladder cancer.
Gallstones are very common but 50–80% of people with gallstones are asymptomatic and do not need surgery; their stones are noticed incidentally on imaging tests of the abdomen (such as ultrasound or CT) done for some other reason. Of the more than 20 million people in the US with gallstones, only about 30% will eventually require cholecystectomy to relieve symptoms (pain) or treat complications.
Biliary colic, or pain caused by gallstones, occurs when a gallstone temporarily blocks the bile duct that drains the gallbladder. Typically, pain from biliary colic is felt in the right upper part of the abdomen, is moderate to severe, and goes away on its own after a few hours when the stone dislodges. Biliary colic usually occurs after meals when the gallbladder contracts to push bile out into the digestive tract. After a first attack of biliary colic, more than 90% of people will have a repeat attack in the next 10 years. Repeated attacks of biliary colic are the most common reason for removing the gallbladder, and lead to about 300,000 cholecystectomies in the US each year.

Ascending cholangitis
Ascending cholangitis, also known as acute cholangitis or simply cholangitis, is inflammation of the bile duct, usually caused by bacteria ascending from its junction with the duodenum (first part of the small intestine). It tends to occur if the bile duct is already partially obstructed by gallstones. Cholangitis can be life-threatening, and is regarded as a medical emergency. Characteristic symptoms include yellow discoloration of the skin or whites of the eyes, fever, abdominal pain, and in severe cases, low blood pressure and confusion.
Endoscopic retrograde cholangiopancreatography
Endoscopic retrograde cholangiopancreatography (ERCP) is a technique that combines the use of endoscopy and fluoroscopy to diagnose and treat certain problems of the biliary or pancreatic ductal systems. It is primarily performed by highly skilled and specialty trained gastroenterologists. Through the endoscope, the physician can see the inside of the stomach and duodenum, and inject a contrast medium into the ducts in the biliary tree and pancreas so they can be seen on radiographs.
Abdominal pain
Abdominal pain, also known as a stomach ache, is a symptom associated with both non-serious and serious medical issues. Common causes of pain in the abdomen include gastroenteritis and irritable bowel syndrome. About 15% of people have a more serious underlying condition such as appendicitis, leaking or ruptured abdominal aortic aneurysm, diverticulitis, or ectopic pregnancy. In a third of cases the exact cause is unclear.
