The mortality rate for acute cholecystitis was 9.4 per cent. Those patients who underwent cholecystostomy had a mortality rate of 27.3 per cent, cholecystectomy 2.2 per cent, cholecystectomy and choledochotomy 7.4 per cent. Factors found to have an adverse effect on mortality in acute cholecystitis included sphincterotomy, perforation or gangrene of the gallbladder and cholagitis. Cholecystectomy is the operation of choice in acute cholecystitis in the absence of or history of jaundice or evidence of a common duct stone or cholangitis. Operative cholangiography and pressure and flow measurements through the cystic duct are advocated to avoid a retained common duct stone. Cholecystostomy should be reserved for the critically ill patient or a patient who deteriorates during operation, and it should be done only if the operator visualizes clear bile returning through the cystic duct.

A prospective study of 397 patients with primary biliary operations performed for benign disease included a perioperative culture of the bile. Two main groups of patients in whom bacteria in the bile and, thus, probably increased risk postoperative infection was common, are patients undergoing emergency operation (60 per cent bacteria in the bile, as compared with 22 per cent in those with elective operations) and patients with a history of acute cholecystitis or pancreatitis, or both, or jaundice (49 per cent bacteria in the bile with a positive history as compared with 11 per cent without). The rate of infection was 2.8 per cent in high-risk groups, as compared with 0.6 per cent in patients undergoing elective operative procedures with no history of acute cholecystitis, pancreatitis or jaundice. Thus, antibiotics can probably be reserved for those patients who had emergency surgical treatment and for those with elective operations and a history of acute cholecystitis, pancreatitis or jaundice. In addition, antibiotic prophylaxis might be indicated for all patients who are 75 years of age or older, as bacteria in the bile seems to be common in this age group even without a history of the aforementioned complications.

Although there are many complementary and supplementary types of diagnostic imaging of the liver, a logical sequence for most liver pathology begins with high-quality ultrasound. It is noninvasive and inexpensive but very operator dependent. In other settings, CT may be the preferable screening modality, as it gives an excellent picture of the global anatomy and is easily reproducible. Frequently, the two modalities are complementary and indicated; on other occasions, one method will suffice. Radionuclide evaluation of the liver is usually reserved for hepatobiliary imaging for biliary obstruction or the question of acute cholecystitis and tagged-red cell scanning for hemangioma. It is also frequently used for gallium scanning in hepatoma, but lymphoma and inflammatory diseases are also gallium avid. The invasive imaging tests of the liver--angiography and transhepatic and endoscopic retrograde cholangiography--are performed when insufficient information is obtained by the other methods (as in diagnostic transhepatic cholangiography) or when the procedure offers therapy (as for biliary drainage, percutaneous transhepatic removal of common bile duct stones, percutaneous cholecystosis with gallstone dissolution and liver embolization, or the angiographic evaluation for portal shunting or liver resection). The impact of magnetic resonance imaging and fourth-generation raid angiotomography CT scanning has yet to be felt. The use of intraoperative ultrasound is to be encouraged prior to liver resection because it can demonstrate lesions as small as 3 mm in diameter.

As a result of important advances in medical imaging, the oral cholecystogram is no longer the primary test of gallbladder function and anatomy. Real-time ultrasonography and cholescintigraphy, both highly sensitive and specific tests, are the two major methods for assessing gallbladder pathology. Oral cholecystography, endoscopic retrograde pancreatography, and percutaneous gallbladder puncture serve as supplementary tests. Decisions about which test to use depend on the kind of gallbladder disease that is suspected as well as the estimated likelihood of the disease before the information is obtained from the procedure. Thus, ultrasonography is the test of choice for chronic cholecystitis, with oral cholecystography reserved for situations in which the diagnosis is uncertain after ultrasonography. When acute cholecystitis is suspected, ultrasonography is also the test of choice in most patients, and cholescintigraphy is used to resolve uncertainty.

Bactobilia is a frequent accompaniment of obstruction in the biliary tract, organisms present being normal intestinal aerobes and anaerobes. Bacterial colonisation of the bile may occur asymptomatically, may predispose to infection postoperatively, or may be associated with an attack of acute cholecystitis, occurring secondary to obstruction. The choice of an antimicrobial regimen for biliary infection should take into account the expected antibiotic sensitivities of organisms colonising bile, whether biliary obstruction or bacteraemia is present, and the activity of the antibiotic in bile. Often, high biliary concentrations of an antibiotic cannot be achieved due to obstruction, and in many cases high blood and tissue concentrations are of greater importance. Surgical prophylaxis should be reserved for patients at high risk of bactobilia (e.g. the elderly), when obstruction is present, for immunosuppressed patients, and those with artificial heart valves. A single perioperative dose of a 'first' or 'second generation' cephalosporin, gentamicin, or co-trimoxazole is effective. Antibiotic therapy for acute cholecystitis should be instituted if there is evidence of systemic toxicity, when surgery is to be delayed, or in patients with identified risk factors for bactobilia. Ampicillin or a cephalosporin may be appropriate in less severe disease, while in seriously ill patients, an aminoglycoside or cephalosporin with metronidazole or clindamycin is appropriate. Oral regimens include amoxycillin, an oral cephalosporin, or co-trimoxazole, in combination with metronidazole. In acute cholangitis, systemic therapy similar to that recommended for acute cholecystitis is indicated. Patients with recurrent cholangitis may have relatively antibiotic-resistant bacteria and efforts should be made to obtain a bacteriological diagnosis. Long term suppressant therapy with oral agents such as amoxycillin, cephalexin, or co-trimoxazole may be tried.

Acute biliary tract disease complicated intrauterine pregnancy in 26 patients seen during a 5 year period. Biliary symptoms were distinct and occurred during the first trimester in 7 patients, the second trimester in 5 patients, the third trimester in 12 patients, and in two early postpartum patients. Nine patients had marked hyperamylasemia which resolved with medical management, and no severe cases of pancreatitis occurred. Ultrasonography was used to confirm the presence of gallstones in 18 patients and demonstrated dilated intrahepatic ducts in one of two patients with surgically proved choledocholithiasis. Nineteen patients had cholecystectomy and cholangiography, and 4 had common bile duct explorations. Only two of seven patients who presented in the first trimester had term pregnancy. Diagnosis of cholelithiasis in pregnancy by ultrasonography is accurate and reliable. The risk to the fetus of radionuclide scanning and conventional radiography is not justified. Secondary hyperamylasemia is common but responds to conservative therapy. Operation may be delayed until delivery in most patients, with urgent exploration reserved for uncertainty in diagnosis, choledocholithiasis, or acute cholecystitis that does not resolve with medical measures.

The authors present four cases of acute acalculous cholecystitis complicating major burn injury and review the recent literature on acalculous cholecystitis. All patients were men and ranged in age from 22 to 40 years. The mean extent of the burn was 50% of the total body surface area, with an average 29% third-degree component. All four patients survived. Because of their severity, major burn injuries expose patients to many risks, including acute acalculous cholecystitis. Recent experimental evidence supports a vascular insult through the activation of Factor XII pathways as the initial event. A diagnosis is made on clinical grounds, supported by laboratory and ultrasonographic findings, in a patient with a burn covering more than 30% of the total body surface area and who has signs of acute cholecystitis. Cholecystectomy is the treatment of choice; tube cholecystostomy is reserved for critically ill patients.

Because of the high diagnostic yield, its widespread availability and the possibility of bedside examinations, US has become the imaging modality of choice in patients with acute right upper quadrant pain caused by inflammatory disorders such as liver abscesses, acute cholangitis and acute cholecystitis. Computed tomography (CT) can be reserved for more complex cases. US, often in combination with fluoroscopy, is also widely used to control interventions. In patients with liver abscesses the therapeutic strategy is determined by the size of the abscess, its uni- or multifocal presentation and the causative micro-organisms cultured after diagnostic percutaneous aspiration. Small-sized pyogenic abscesses (< 3 cm), most fungal and amoebic abscesses can be treated medically. Large-sized pyogenic abscesses should be drained percutaneously and can be cured in 75-90%. Surgery should be restricted to patients with prolonged sepsis after percutaneous drainage and patients with infected pre-existing hepatic lesions. In patients with acute cholangitis drainage of the infected bile is essential. Invasive imaging such as percutaneous or endoscopic cholangiography procedures such as nasobiliary drainage, stent placement and sphincterotomy has decreased mortality rates dramatically. Percutaneous drainage should be considered in patients in whom endoscopic procedures fail. Surgery may have a place in the treatment of bile duct obstruction which causes cholangitis. In patients with suspected acute cholecystitis, imaging modalities such as cholescintigraphy and CT can be reserved for patients with inconclusive sonographic studies and more complex cases. The contribution of percutaneous gallbladder aspiration and culture to diagnose acute cholecystitis seems limited. Percutaneous cholecystostomy is an effective procedure with a low morbidity and mortality for high-risk patients. The drainage catheter in the gallbladder does not interfere with cholecystectomy at a later stage in patients with calculous cholecystitis. In most patients with acalculous cholecystitis, percutaneous cholecystectomy provides a definitive treatment.

Initial therapy of acute cholecystitis and cholangitis is directed towards general support of the patient, including fluid and electrolyte replacement, correction of metabolic imbalances and antibacterial therapy. Factors affecting the efficacy of antibacterial therapy include the activity of the agent against the common biliary tract pathogens and pharmacokinetic properties such as tissue distribution and the ratio of concentration in both bile and serum to the minimum inhibitory concentration for the expected micro-organism. Antimicrobial therapy is usually empirical. Initial therapy should cover the Enterobacteriaceae, in particular Escherichia coli. Activity against enterococci is not required since their pathogenicity in biliary tract infections remains unclear. Coverage of anaerobes, in particular Bacteroides spp., is warranted in patients with previous bile duct-bowel anastomosis, in the elderly and in patients in serious clinical condition. In patients with acute cholecystitis or cholangitis of moderate clinical severity, monotherapy with a ureidopenicillin--mezlocillin or piperacillin--is at least as effective as the combination of ampicillin plus aminoglycoside. In severely ill patients with septicaemia, an antibacterial combination is preferable. Therapy with aminoglycosides, mostly for Pseudomonas aeruginosa-related infections, should not exceed a few days because the risk of nephrotoxicity seems to be increased during cholestasis. Relief of biliary obstruction is mandatory, even if there is clinical improvement with conservative therapy, because cholangitis is most likely to recur with continued obstruction. Emergency invasive therapy is reserved for patients who fail to show a clinical response to antibacterial therapy within the first 36 to 48 hours or for those who deteriorate after an initial clinical improvement. Immediate surgery is indicated for gangrenous cholecystitis and perforation with peritonitis. Long-term administration of antibacterials is required for recurrent cholangitis, as seen in bile duct-bowel anastomosis. Oral cotrimoxazole (trimethoprim/sulfamethoxazole) is the preferred agent. Wound infection rates after biliary tract surgery can be significantly reduced by preoperative administration of prophylactic antibacterials. Newer generation beta-lactams have not proven to be of greater benefit than older agents such as cefuroxime or cefazolin. Antibacterial prophylaxis before endoscopic retrograde cholangiopancreatography (ERCP) should be reserved for patients with obstructive jaundice, since the risk of infectious complications seems to be strongly associated with this clinical condition. Failure to achieve full biliary drainage is the most important factor in predicting septicaemia, and prophylaxis should be prolonged until the bile duct is unobstructed. Piperacillin, cefazolin, cefuroxime, cefotaxime and ciprofloxacin are effective for this indication.

Traditionally, cholecystectomy in cirrhotic patients has been reserved for patients with severe biliary disease, because of the high morbidity and mortality in cirrhotic patients undergoing this procedure. Laparoscopic cholecytectomy (LC) was originally contraindicated in cirrhotic patients because of the associated portal hypertension and coagulopathy. This study examined the safety of LC in Child's class A patients.A review was conducted of all patients with cirrhosis who underwent cholecystectomy at our hospital between 1990 and 1998.Fifteen patients with cirrhosis had their gallbladder removed laparoscopically during that time period. All patients were Child's class A. The average age was 59 (range, 36-85). The operative indications included acute cholecystitis (5 patients), biliary pacreatitis (4 patients), biliary colic (5 patients), and cholangitis (1 patients). Six patients had known cirrhosis, and 9 were examined intraoperatively. The average operative time was 105 minutes. None of the patients required a blood transfusion. No intraoperative or postoperative complications occurred. No deaths occurred. Postoperative stay was 3 days or less in all but 3 patients.These results compare favorably to other published studies from outside of the United States. Based on our findings, we believe LC can be performed safely in patients with class A cirrhosis.
