Due to the increased risk for gallbladder cancer, the recommended treatment is cholecystectomy which usually includes pre-operative or intra-operative imaging of the biliary tree. Cholecystectomy may be performed via an open incision or via laparoscopic methods, but gallbladder anatomy and consistency may complicate the operation.

Initial management includes the relief of symptoms and correcting electrolyte and fluid imbalance that may occur with vomiting. Antiemetics, such as dimenhydrinate, are used to treat the nausea. Pain may be treated with anti-inflammatories, NSAIDs such as ketorolac or diclofenac. Opioids, such as morphine, less commonly may be used. NSAIDs are more or less equivalent to opioids. Hyoscine butylbromide, an antispasmodic, is also indicated in biliary colic.

In biliary colic, the risk of infection is minimal and therefore antibiotics are not required. Presence of infection indicates cholecystitis.

It is unclear whether those experiencing a gallstone attack should receive surgical treatment or not. The scientific basis to assess whether surgery outperformed other treatment was insufficient and better studies were needed as of a SBU report in 2017. Treatment of biliary colic is dictated by the underlying cause. The presence of gallstones, usually visualized by ultrasound, generally necessitates a surgical treatment (removal of the gall bladder, typically via laparoscopy). Removal of the gallbladder with surgery, known as a cholecystectomy, is the definitive surgical treatment for biliary colic. A 2013 Cochrane review found tentative evidence to suggest that early gallbladder removal may be better than delayed removal. Early laparoscopic cholescystectomy happens within 72 hours of diagnosis. In a Cochrane review that evaluated receiving early versus delayed surgery, they found that 23% of those who waited on average 4 months ended up in hospital for complications, compared to none with early intervention with surgery. Early intervention has other advantages including reduced number of visits to the emergency department, less conversions to an open surgery, less operating time required, reduced time in hospital post operatively. The Swedish agency SBU estimated in 2017 that increasing acute phase surgeries could

free multiple in-hospital days per patient and would additionally spare pain and suffering in wait of receiving an operation. The report found that those with acute inflammation of the gallbladder can be surgically treated in the acute phase, within a few days of symptom debut, without increasing the risk for complications (compared to when the surgery is done later in an asymptomatic stage).

In the Western world, about 15% of all people have gallstones in their gallbladder but the majority are unaware of this and have no symptoms. Over ten years, 15–26% will suffer one or more episodes of biliary colic (abdominal pain due to the passage of gallstones through the bile duct into the digestive tract), and 2–3% will develop complications of obstruction: acute pancreatitis, cholecystitis or acute cholangitis. Prevalence of gallstone disease increases with age and body mass index (a marker of obesity). However, the risk is also increased in those who lose weight rapidly (e.g. after weight loss surgery) due to alterations in the composition of the bile that makes it prone to form stones. Gallstones are slightly more common in women than in men, and pregnancy increases the risk further.

Gallstone risk increases for females (especially before menopause) and for people near or above 40 years; the condition is more prevalent among both North and South Americans and among those of European descent than among other ethnicities. A lack of melatonin could significantly contribute to gallbladder stones, as melatonin inhibits cholesterol secretion from the gallbladder, enhances the conversion of cholesterol to bile, and is an antioxidant, which is able to reduce oxidative stress to the gallbladder. Researchers believe that gallstones may be caused by a combination of factors, including inherited body chemistry, body weight, gallbladder motility (movement), and low calorie diet. The absence of such risk factors does not, however, preclude the formation of gallstones.

Nutritional factors that may increase risk of gallstones include constipation; eating fewer meals per day; low intake of the nutrients folate, magnesium, calcium, and vitamin C; low fluid consumption; and, at least for men, a high intake of carbohydrate, a high glycemic load, and high glycemic index diet. Wine and whole-grained bread may decrease the risk of gallstones.

Rapid weight loss increases risk of gallstones. Patients taking orlistat, a weight loss drug, may already be at increased risk for the formation of gallstones. Weight loss with orlistat can increase the risk of gallstones. On the contrary, ursodeoxycholic acid (UDCA), a bile acid, also a drug marketed as Ursodiol, appears to prevent formation of gallstones during weight loss. A high fat diet during weight loss also appears to prevent gallstones.

Cholecystokinin deficiency caused by celiac disease increases risk of gallstone formation, especially when diagnosis of celiac disease is delayed.

Pigment gallstones are most commonly seen in the developing world. Risk factors for pigment stones include hemolytic anemias (such as from sickle-cell disease and hereditary spherocytosis), cirrhosis, and biliary tract infections. People with erythropoietic protoporphyria (EPP) are at increased risk to develop gallstones. Additionally, prolonged use of proton pump inhibitors has been shown to decrease gallbladder function, potentially leading to gallstone formation.

Cholesterol modifying medications can affect gallstone formation. Statins inhibit cholesterol synthesis and there is evidence that their use may decrease the risk of getting gallstones. Fibrates increase cholesterol concentration in bile and their use has been associated with an increased risk of gallstones.

Gallstones are a valuable by-product of animals butchered for meat because their use as a purported antipyretic and antidote in the folk remedies of some cultures, in particular, in China. The finest gallstones tend to be sourced from old dairy cows, termed calculus bovis or "niu-huang" (yellow thing of cattle) in Chinese. Much as in the manner of diamond mines, slaughterhouses carefully scrutinize workers for gallstone theft.

Laparoscopic cholecystectomy has been used to treat the condition when due to dyskinesia of the gallbladder.

Symptoms may persist after cholecystectomy, and have been linked to the use of proton pump inhibitors.

Osteopathic treatment, oral magnesium supplementation with 325 mg and the use of digestive enzymes caused improvement in one case.

Women are almost twice as likely as men to form gallstones especially during the fertile years; the gap narrows after the menopause. The underlying mechanism is female sex hormones; parity, oral contraceptive use and estrogen replacement therapy are established risk factors for cholesterol gallstone formation. Female sex hormones adversely influence hepatic bile secretion and gallbladder function. Estrogens increase cholesterol secretion and diminish bile salt secretion, while progestins act by reducing bile salt secretion and impairing gallbladder emptying leading to stasis. A new 4th generation progestin, drospirenone, used in some oral contraceptives may further heighten the risk of gallstone disease and cholecystectomy; however, the increased risk is quite modest and not likely to be clinically meaningful.

A retrospective (historical) cohort study was performed on a very large data base including 1980 and 1981 Medicaid billing data from the states of Michigan and Minnesota in which 138,943 users of OCs were compared with 341,478 nonusers. Oral contraceptives were shown as risk factors for gallbladder disease, although the risk is of sufficient magnitude to be of potential clinical importance only in young women.

The 1984 Royal College of General Practitioners' Oral Contraception Study suggests that, in the long-term, oral contraceptives are not associated with any increased risk of gallbladder disease, although there is an acceleration of the disease in those women susceptible to it.

Newer research suggests otherwise. A 1993 meta-analysis concludes that oral contraceptive use is associated with a slightly and transiently increased rate of gallbladder disease, but laters confirms that modern low-dose oral contraceptives are safer than older formulas, though an effect cannot be excluded.

A 2001 comparative study of the IMS LifeLink Health Plan Claims Database interpreted that in a large cohort of women using oral contraceptives, there was found a small, statistically significant increase in the risk of gallbladder disease associated with desogestrel, drospirenone and norethisterone compared with levonorgestrel. No statistically significant increase in risk was associated with the other formulations of oral contraceptive (etynodiol diacetate, norgestrel and norgestimate).

Treatment involves an operation called a choledocholithotomy, which is the removal of the gallstone from the bile duct using ERCP, although surgeons are now increasingly using laparoscopy with cholangiography. In this procedure, tiny incisions are made in the abdomen and then in the cystic duct that connects the gallbladder to the bile duct, and a thin tube is introduced to perform a cholangiography. If stones are identified, the surgeon inserts a tube with an inflatable balloon to widen the duct and the stones are usually removed using either a balloon or tiny basket.

If laparoscopy is unsuccessful, an open choledocholithotomy is performed. This procedure may be used in the case of large stones, when the duct anatomy is complex, during or after some gallbladder operations when stones are detected, or when ERCP or laparoscopic procedures are not available.

Typically, the gallbladder is then removed, an operation called cholecystectomy, to prevent a future occurrence of common bile duct obstruction or other complications.

Cholangitis requires admission to hospital. Intravenous fluids are administered, especially if the blood pressure is low, and antibiotics are commenced. Empirical treatment with broad-spectrum antibiotics is usually necessary until it is known for certain which pathogen is causing the infection, and to which antibiotics it is sensitive. Combinations of penicillins and aminoglycosides are widely used, although ciprofloxacin has been shown to be effective in most cases, and may be preferred to aminoglycosides because of fewer side effects. Metronidazole is often added to specifically treat the anaerobic pathogens, especially in those who are very ill or at risk of anaerobic infections. Antibiotics are continued for 7–10 days. Drugs that increase the blood pressure (vasopressors) may also be required to counter the low blood pressure.

A prospective study in 1994 noted that body mass index remains the strongest predictor of symptomatic gallstones among young women. Other risk factors are having over four pregnancies, weight gain, and cigarette smoking. Alcohol was shown to have an inverse relationship between use and gallbladder disease.

Simple cholecystectomy is suitable for type I patients. For types II–IV, subtotal cholecystectomy can be performed to avoid damage to the main bile ducts. Cholecystectomy and bilioenteric anastomosis may be required. Roux-en-Y hepaticojejunostomy has shown good outcome in some studies.

The clinical course of biliary sludge can do one of three things: (1) it can resolve completely, (2) wax and wane, or (3) progress to gallstones. If the biliary sludge has a cause (e.g. pregnancy), it oftentimes is resolved when the underlying cause is removed.

The assertion that porcelain gallbladder increases the incidence of gallbladder cancer is widely taught in medical schools but is based on studies from 1931 and 1962. A prominent study aid for surgical residents even states that the risk of cancer in a porcelain gallbladder is 15%. The precise nature of the association between gallbladder cancer and porcelain gallbladder is uncertain. Two articles published in 2001 examined the association between cancer of the gallbladder and calcified gallbladder. The first study reviewed 10,741 cholecystectomies and found that the 88 patients with gallbladder cancer did not have calcified gallbladders while the 15 patients with porcelain gallbladders did not have gallbladder cancer. The second study reviewed 25,900 gallbladder specimens and found 150 patients with cancer and 44 patients with calcified gallbladders of two types (intramural calcification and selective mucosal calcification). The selective mucosal calcification group showed a 7% incidence of cancer with a significant odds ratio of 13.89.

An article published in 2013 reviewed 111 studies and found 340 patients with gallbladder wall calcification showed a 21% overall rate of gallbladder malignancy; however, when studies with obvious selection bias were excluded the rate of gallbladder malignancy fell to 6%. Comparatively, a matched cohort without gallbladder calcification showed a 1% rate of gallbladder malignancy.

For most people with acute cholecystitis, the treatment of choice is surgical removal of the gallbladder, laparoscopic cholecystectomy. Laparoscopic cholecystectomy is performed using several small incisions located at various points across the abdomen. Several studies have demonstrated the superiority of laparoscopic cholecystectomy when compared to open cholecystectomy (using a large incision in the right upper abdomen under the rib cage). People undergoing laparoscopic surgery report less incisional pain postoperatively as well as having fewer long term complications and less disability following the surgery. Additionally, laparoscopic surgery is associated with a lower rate of surgical site infection.

During the days prior to laparoscopic surgery, studies showed that outcomes were better following early removal of the gallbladder, preferably within the first week. Early laparoscopic cholecystectomy (within 7 days of visiting a doctor with symptoms) as compared to delayed treatment (more than 6 weeks) may result in shorter hospital stays and a decreased risk of requiring an emergency procedure. There is no difference in terms of negative outcomes including bile duct injury or conversion to open cholecystectomy. For early cholecystectomy, the most common reason for conversion to open surgery is inflammation that hides Calot's triangle. For delayed surgery, the most common reason was fibrotic adhesions.

For patients without symptoms, no treatment is recommended. If patients become symptomatic and/or develop complications, cholecystectomy is indicated. For those who are poor surgical candidates, endoscopic sphincterotomy may be performed to reduce the risk of developing pancreatitis.

Supportive measures may be instituted prior to surgery. These measures include fluid resuscitation. Intravenous opioids can be used for pain control.

Antibiotics are often not needed. If used they should target enteric organisms (e.g. Enterobacteriaceae), such as "E. coli" and "Bacteroides". This may consist of a broad spectrum antibiotic; such as piperacillin-tazobactam, ampicillin-sulbactam, ticarcillin-clavulanate (Timentin), a third generation cephalosporin (e.g.ceftriaxone) or a quinolone antibiotic (such as ciprofloxacin) and anaerobic bacteria coverage, such as metronidazole. For penicillin allergic people, aztreonam or a quinolone with metronidazole may be used.

In cases of severe inflammation, shock, or if the person has higher risk for general anesthesia (required for cholecystectomy), an interventional radiologist may insert a percutaneous drainage catheter into the gallbladder ('percutaneous cholecystostomy tube') and treat the person with antibiotics until the acute inflammation resolves. A cholecystectomy may then be warranted if the person's condition improves.

Homeopathic approaches to treating cholecystitis have not been validated by evidence and should not be used in place of surgery.

Although there is no curative treatment, several clinical trials are underway that aim to slow progression of this liver disease. Obeticholic acid is being investigated as a possible treatment for PSC due to its antifibrotic effects. Simtuzumab is a monoclonal antibody against the pro-fibrotic enzyme LOXL2 that is being developed as a possible therapy for PSC.

Common bile duct stone, also known as choledocholithiasis, is the presence of gallstones in the common bile duct (thus "" + ""). This condition causes jaundice and liver cell damage. Treatment is by cholecystectomy and ERCP.

Mirizzi's syndrome occurs in approximately 0.1% of patients with gallstones. It is found in 0.7 to 2.5 percent of cholecystectomies.

It affects males and females equally, but tends to affect older people more often. There is no evidence of race having any bearing on the epidemiology.

In simple cases of obstruction, where there are no complications, a variety of non-surgical and surgical techniques are used to remove the enterolith. These include crushing the enterolith and milking it back to the stomach or forward to the colon, surgical removal via an uninvolved segment of the gastrointestinal tract, and resection of the involved segment.

Some individuals may benefit from diet modification, such as a reduced fat diet, following cholecystectomy. The liver produces bile and the gallbladder acts as reservoir. From the gallbladder, bile enters the intestine in individual portions. In the absence of gallbladder, bile enters the intestine constantly, but in small quantities. Thus, it may be insufficient for digestion of fatty foods. Postcholecystectomy syndrome treatment depends on the identified violations that led to it. Typically, the patient is recommended dietary restriction table with fatty foods, enzyme preparations, antispasmodics, sometimes cholagogue.

If the pain is caused by biliary microlithiasis, oral ursodeoxycholic acid can alleviate the condition.

A trial of bile acid sequestrant therapy is recommended for bile acid diarrhoea.

Equine enteroliths are found by walking pastures or turning over manure compost piles to find small enteroliths, during necroscopy, and increasingly, during surgery for colic. Therefore, the incidence of asymptomatic enteroliths is unknown.

Equine enteroliths typically are smoothly spherical or tetrahedral, consist mostly of the mineral struvite (ammonium magnesium phosphate), and have concentric rings of mineral precipitated around a nidus.

Enteroliths in horses were reported widely in the 19th century, infrequently in the early 20th century, and now increasingly. They have also been reported in zebras: five in a zoo in California and one in a zoo in Wisconsin. Struvite enteroliths are associated with elevated pH and mineral concentrations in the lumen. In California, struvite enteroliths are associated also with a high proportion of alfalfa in the feed and less access to grass pasture. This association has been attributed to the cultivation of alfalfa on serpentine soils, resulting in high concentrations of magnesium in the alfalfa.

Medication (to prevent spasms) or Sphincterotomy (surgical procedure to cut the muscle) are the standard treatments for sphincter of Oddi dysfunction. One or the other may be better based on the classification of the condition.

There is a 2-3:1 male-to-female predilection in primary sclerosing cholangitis. PSC can affect men and women at any age, although it is commonly diagnosed in the fourth decade of life, most often in the presence of inflammatory bowel disease (IBD). PSC progresses slowly and is often asymptomatic, so it can be present for years before it is diagnosed and before it causes clinically significant consequences. There is relatively little data on the prevalence and incidence of primary sclerosing cholangitis, with studies in different countries showing annual incidence of 0.068–1.3 per 100,000 people and prevalence 0.22–8.5 per 100,000; given that PSC is closely linked with ulcerative colitis, it is likely that the risk is higher in populations where UC is more common. In the United States, an estimated 29,000 individuals have PSC.
