If silent gallstones are discovered in an
individual at age 65 (or older), the chance of developing symptoms from the
gallstones is only 20% (or less) assuming a life span of 75 years. In this
instance, it is reasonable not to treat the individual.
In younger
individuals, no treatment also may be appropriate if the individuals have
serious, life-threatening diseases, for example, serious
heart disease, that are
likely to shorten their life span.
On the other hand, in healthy young
individuals, treatment should be considered even for silent gallstones because
the individuals' chances of developing symptoms from the gallstones over a
lifetime will be higher. Once symptoms begin, treatment should be recommended
since further symptoms are likely and more serious complications can be
prevented.
Cholecystectomy
Cholecystectomy (removal of the gallbladder surgically) is the standard treatment for gallstones in the gallbladder. Surgery may be done through a large abdominal incision or laparoscopically through small punctures of the abdominal wall. Laparoscopic surgery results in less pain and a faster recovery. Cholecystectomy has a low rate of complications, but serious complications such as damage to the bile ducts and leakage of bile occasionally occur. There also is risk associated with the general anesthesia that is necessary for either type of surgery. Problems following removal of the gallbladder are few. Digestion
of food is not affected, and no change in diet is necessary. Chronic
diarrhea occurs in approximately 10% of patients.
Sphincterotomy and extraction of gallstones
Sometimes a gallstone may be stuck in the hepatic or common bile ducts. In such situations, there usually are gallstones in the gallbladder as well, and cholecystectomy is necessary. It may be possible to remove the gallstone stuck in the duct at the time of surgery, but this may not always be possible. An alternative means for removing gallstones in the duct before or after cholecystectomy is with sphincterotomy followed by extraction of the gallstone.
Sphincterotomy involves cutting the muscle of the common bile duct (sphincter) at the junction of the common bile duct and the duodenum in order to allow easier access to the common bile duct. The cutting is done with an electrosurgical instrument passed through the same type of endoscope that is used for ERCP. After the sphincter is cut, instruments may be passed through the endoscope and into the hepatic and common bile ducts to grab and pull out the gallstone or to crush the gallstone. It also is possible to pass a lithotripsy instrument that uses high frequency sound waves to break up the gallstone. Complications of sphincterotomy and extraction of gallstones include
risks associated with general anesthesia, perforation of the bile ducts or duodenum, bleeding, and pancreatitis.
Oral dissolution therapy
It is possible to dissolve some cholesterol gallstones with medication taken orally. The medication is a naturally-occurring bile acid called ursodeoxycholic acid or ursodiol
(Actigall, Urso). Bile acids are one of the detergents that the liver secretes into bile to dissolve cholesterol. Although one might expect therapy with ursodiol to work by increasing the amount of bile acids in bile and thereby cause the cholesterol in gallstones to dissolve, the mechanism of ursodiol's action actually is different. Ursodiol reduces the amount of cholesterol secreted in bile. The bile then has less cholesterol and becomes capable of dissolving the cholesterol in the gallstones.
There are important limitations to the use of ursodiol:
It is only effective for cholesterol gallstones and
not pigment gallstones.
It works only for small gallstones, less than 1-1.5
cm in diameter.
It takes one to two years for the gallstones to dissolve, and many of the gallstones reform following cessation of
treatment.
Due to these limitations, ursodiol generally is used only in individuals with smaller gallstones that are likely to have a very high cholesterol content and who are at high risk for surgery because of ill health. It also is reasonable to use ursodiol in individuals whose gallstones were
perhaps formed because of a transient event, for example, rapid loss of weight, since the gallstones would not be expected to recur following successful dissolution.
Extracorporeal shock-wave lithotripsy
Extracorporeal shock-wave lithotripsy (ESWL) is an infrequently used method for treating gallstones, particularly those lodged in bile ducts. ESWL generators produces shock waves outside of the body that are then focused on the gallstone. The shock waves shatter the gallstone, and the resulting pieces of the gallstone either drain into the intestine on their own or are extracted endoscopically.
Abdominal pain is pain in the belly and can be acute or chronic. Causes include inflammation, distention of an organ, and loss of the blood supply to an organ. Abdominal pain can reflect a major problem with one of the organs in the abdomen such as the appendix, gallbladder, large and small intestine, pancreas, liver, colon, duodenum, and spleen.
Crohn's disease is a chronic inflammatory disease,
primarily involving the small and large intestine, but which can
affect other parts of the digestive system as well. Abdominal pain, diarrhea, vomiting, fever, and weight loss are
common symptoms.
Cirrhosis of the liver refers to a disease in which normal liver cells are replaced by scar tissue caused by alcohol and viral hepatitis B and C. This disease leads to abnormalities in the liver's ability to handle toxins and blood flow, causing internal bleeding, kidney failure, mental confusion, coma, body fluid accumulation, and frequent infections. Symptoms include yellowing of the skin, itching, and fatigue.
Liver disease can be cause by a variety of things including infection (hepatitis), diseases such as gallstones, high cholesterol or triglycerides, blood flow obstruction to the liver, and toxins (medications and chemicals). Symptoms of liver disease depends upon the cause; however, common symptoms may include nausea, vomiting, upper right abdominal pain, and jaundice. Treatment depends upon the cause of the liver disease.
Nausea is an uneasiness of the stomach that often precedes vomiting. Nausea and vomiting are not diseases, but they are symptoms of many conditions. The causes of vomiting differ according to age, and treatment depends upon the cause of nausea and vomiting.
Pancreatitis is a rare disease in which the pancreas becomes inflamed, occurring when digestive enzymes are activated and begin attacking the pancreas causing damage to the gland. There are two types of pancreatitis, acute and chronic. Most commonly caused by alcohol or gallstones, it can lead to bleeding in the gland, serious tissue damage, infection, and cysts. Enzymes and toxins may then enter the bloodstream and seriously injure organs, such as the heart, lungs, and kidney.
Jaundice is a yellowish staining of the skin and whites of the eyes (sclerae) with bilirubin, the pigment found in bile. Jaundice can be an indicator of liver or gallbladder disease, or it may result from the rupture of red blood cells (hemolysis).
Alcoholism is a disease that includes alcohol craving and continued drinking despite repeated alcohol-related problems, such as losing a job or getting into trouble with the law.
Stool color is generally brown. When stool color changes, often, an individual becomes concerned. The presence of the bilirubin in bile is generally responsible for stool color. Bilirubin concentration can vary bile color from light yellow to almost black in color. Changes in bilirubin can cause stool to turn green, gray, or clay-like in color. Intestinal bleeding may turn stool black, tarry, red, maroon, or smelly stool. Medication and food may also affect stool color.
Dyspepsia (indigestion) is a functional disease in which the gastrointestinal organs, primarily the stomach and first part of the small intestine, function abnormally. It is a chronic disease in which the symptoms fluctuate infrequency and intensity. Symptoms of dyspepsia include upper abdominal pain, belching, nausea, vomiting, abdominal bloating, early satiety, and abdominal distention (swelling). These symptoms are most often provoked by eating.
Pleurisy, an inflammation of the lining around the lungs, is associated with sharp chest pain upon breathing in. Cough, chest tenderness, and shortness of breath are other symptoms associated with pleurisy. Pleurisy pain can be managed with pain medication and by external splinting of the chest wall.
Cystic fibrosis is a disease of the mucus and sweat glands. Cystic fibrosis is an inherited disease. The outcome of the disease leaves the body malnourished, bulky and fouls smelling stools, vitamin insufficiency, gas, painful or swollen abdomen, infertility, susceptible to heat emergencies, and respiratory failure. There is no cure for cystic fibrosis, treatment of symptoms is used to manage the disease.
Obesity is the state of being well above one's normal weight. A person has traditionally been
considered to be obese if they are more than 20 percent over their ideal weight.
That ideal weight must take into account the person's height, age, sex, and
build.
Sickle cell anemia (sickle cell disease), a blood disease which shortens life expectancy, is cause by an inherited abnormal hemoglobin. Symptoms may include bacterial infections, painful swelling of the hands and feet, fever, leg ulcers, fatigue, anemia, eye damage, and lung and heart injury. Treatment for sickle cell anemia aims to manage and prevent the worst manifestations of the disease and focuses on therapies that block red blood cells from stacking together, which can lead to tissue and organ damage and pain.
The liver is the largest solid organ in the body, and is actually an gland. The liver has a wide variety of critical functions such as manufacturing proteins and metabolizing fats and carbohydrates. The liver also eliminates harmful biochemical waste products from the body (alcohol, drugs, toxins). The liver secretes bile that aids in digestion. Examples of diseases of the liver include cirrhosis, hepatitis, cancer, and fatty liver. Symptoms of liver disease include bleeding, easy bruising, edema, fatigue, and jaundice.
Pancreatic cysts are collections of fluid within the pancreas. Some are benign, malignant, or pseudocysts. There are two major types of pancreatic cysts, inflammatory cysts and non-inflammatory cysts. Non-inflammatory cysts include: serous cyst adenomas, mucinous cyst adenomas, intraductal papillary mucinous neoplasm (IPMN), and solid pseudopapillary tumor of the pancreas. Symptoms of pancreatic cysts include abdominal pain, jaundice, fever, chills, and sepsis. Treatment depends on the type of cyst, and patient health.
Nausea and vomiting are symptoms that may be caused by many conditions. Antiemetics are drugs that treat nausea and vomiting. Though some antiemetics for motion sickness and mild nausea are available over the counter (OTC), most require a medical evaluation and prescription.
Beta Thalassemia is the most familiar type of thalassemia. Thalassemia is not just one disease but rather a complex series of genetic (inherited) disorders all of which involve underproduction of hemoglobin.
Gallbladder cancer is a rare form of cancer with symptoms that include jaundice, abdominal pain, fever, nausea and vomiting, abdominal lumps, and bloating. Risk factors include being female and Native American. Treatment of gallbladder cancer depends upon the stage of the cancer, the type of gallbladder cancer, and whether the cancer can be removed by surgery.
Alpha thalassemia is a disorder in which the alpha globin protein is underproduced. There are two pairs of genes that carry the code for the alpha chains of hemoglobin. When one gene is impaired, that person is in a carrier state and suffers no medical problems. When four genes are impaired, the production of fetal and adult hemoglobin is prevented, resulting in hydrops fetalis and leading to death before birth.
Pregnancy planning is important to help prevent exposure of the mother and fetus to potentially harmful medications and substances during the early days, and throughout the pregnancy. Nutritional planning, prevention of birth defects, conditions such as high blood pressure, heart disease, diabetes, and kidney disease need careful monitoring. Gestational diabetes, preeclampsia, and pregnancy induced hypertension are conditions that may arise during pregnancy. Immunizations, inherited disorders, exercise, air travel, intercourse, and birth control are important factors to consider when planning a pregnancy.
Digestion is the complex process of turning food you eat into the energy you need to survive. The digestive process also involves creating waste to be eliminated, and is made of a series of muscles that coordinate the movement of food.
Asbestos exposure lung disease is divided into three main types, asbestosis (lung scarring caused by asbestos fibers), disease of the lining of the lung (pleural plaques, scarring, or fluid accumulation), and lung cancer. Mesothelioma is cancer of the lining of the lung caused by asbestos exposure. Cancers of the larynx, throat, kidney, esophagus, and gallbladder have been linked to asbestos exposure. Treatment is dependant upon the type of condition related to asbestos exposure.
Duodenal diverticula (extramural or intramural), or duodenal diverticulum, is a pouch that is attached to the first part of the small intestine (duodenum). The cause of extramural diverticula is not clear, however, it may be congenital. Complications caused by duodenal diverticulum include rupture, gallstones, or pancreatitis. Extramural duodenal diverticula has no symptoms. Treatment is generally surgery.
Choledochal cysts are cysts of the bile ducts. There are several different types of choledochal cysts. These cysts are congenital, however, their cause is not known. Symptoms of choledochal cysts in infants include an enlarged liver and jaundice. In older people, the cysts cause abdominal pain, jaundice, cholangitis, gallstones, and pancreatitis. Treatment for choledochal cysts is surgery.
Fast food consumption and lack of exercise are just a couple of causes of childhood obesity. Health effects of childhood obesity include type 2 diabetes, heart attack, stroke, high cholesterol, asthma, sleep apnea, gallstones, fatty liver disease, GERD, depression, and eating disorders.
