Findings consist of mild-to-moderate right upper quadrant or epigastric tenderness buy 100mg luvox amex. Once gallstones are complicated by an attack of biliary pain 100 mg luvox mastercard, a recurrent pattern is likely to ensue 100mg luvox free shipping, days or weeks apart. Symptomatic gallstones have a more aggressive course than those that are asymptomatic. Although 30% of patients with one episode of biliary pain do not have further episodes, most experience a recurrent pattern that remains fairly constant. These episodes may be sporadic separated by pain-free periods lasting from days to years, during which the patient feels well and the liver biochemistry is normal. However, complications requiring surgery may arise at any time, with a frequency of 1 to 2% per year. Pain lasting more than six to 12 hours, especially if accompanied by persistent vomiting or fever, suggests another process such as cholecystitis or pancreatitis (Table 4). Diagnostic Imaging Detecting gallstones (as opposed to diagnosing clinically symptomatic gallstone disease) is by diagnostic imaging. Plain abdominal x-rays will only identify the 10-15% with high calcium content as radiopaque densities in the right upper quadrant. Ultrasonography is the most sensitive and specific method for detecting gallstones (appearing as echogenic objects that cast an acoustic shadow) or a thickened gallbladder wall (indicating inflammation). Also, if the gallbladder is fibrotic and shrunken, ultrasound may not visualize the gallbladder. Although most episodes of biliary colic resolve spontaneously, pain eventually recurs in 20-40% each year. Because of recurrent attacks of pain and these increased risks, cholecystectomy is indicated once biliary colic develops. The risk of any emergency procedure is greater then elective surgery, so this is why elective cholecystectomy is recommended. Open cholecystectomy The term open connotes the need for an incision to open the abdominal cavity for direct visualization in the course of removing the gallbladder. Open cholecystectomy is usually necessary in Mirizzis syndrome, an infrequent complication in which large gallstones compress First Principles of Gastroenterology and Hepatology A. In addition to the obvious cosmetic appeal, these smaller incisions result in less postoperative pain and shortened recovery time, allowing an early discharge from hospital (sometimes the same day as an outpatient) and return to work. The disadvantages include a somewhat higher complication rate, particularly from common duct injury and retained common duct stones, plus the potential for overuse. In 5% of cases the procedure must be converted to an open cholecystectomy because of technical problems. Laparoscopic cholecystectomy is now the standard for elective removal of the gallbladder in those with significant symptoms (e. Prophylactic cholecystectomy is not warranted in those with asymptomatic stones except for rare cases suspected of developing/ harboring carcinoma of the gallbladder (e. Chronic Calculous Cholecystitis Chronic inflammation of the gallbladder is the most common histological process, often manifest as mild fibrosis of the gallbladder wall with a round cell infiltration and an intact mucosa. Some degree of chronic inflammation inevitably accompanies gallstones, but the stones will have developed first. Even transient obstruction of the cystic duct can produce biliary colic and an element of inflammation that is chemical in origin. There is little correlation between the severity and frequency of such biliary episodes and the degree of inflammation or fibrosis. Chronic inflammation thus may follow the resolution of acute cholecystitis, evolve with recurrent episodes of biliary colic or develop insidiously. It is the presence of true biliary colic which drives the indication for cholecystectomy, not the possible presence of chronic cholecystitis. Clinical Features The clinical features are those of either biliary colic or a previous episode of acute cholecystitis that has resolved leaving the gallbladder chronically inflamed and scarred. The pain characteristically is a constant dull ache in the right upper quadrant or epigastrium, and sometimes also in the right shoulder or back. Flatulence, fatty food intolerance and dyspepsia occur, but are equally frequent in patients without gallstone disease. There may be local tenderness in the right upper quadrant of the abdomen but no peritoneal findings. If the gallbladder is fibrotic and shrunken, ultrasound visualization may be difficult. A nuclear medicine cholescintigraphy scan may be positive with the gallbladder failing to fill, but non-visualization is rather insensitive for chronic cholecystitis, because of frequent false positive and false negative tests. Medical management depends upon gallstone size, gallbladder function and any co-morbid conditions (e. Cholecystectomy provides definitive treatment, removing the stones and the gallbladder, and eliminating recurrences of true biliary pain. Obstruction of the cystic duct results in the gallbladder becoming distended with bile plus an inflammatory exudate or even pus.
