Because of the difficulty in diagnosing acute cholecystitis in critically ill patients with severe intercurrent illness by clinical and imaging methods or percutaneous aspiration of the gallbladder, a trial of percutaneous cholecystostomy was performed in 24 patients in the intensive-care unit with persistent, unexplained sepsis after a complete clinical, laboratory, and radiologic search showed no alternative source of infection. Persistent high fevers, despite antibiotic therapy, were present in all patients, with elevated WBC count in 18 patients, vague abdominal tenderness in 11, and septic shock requiring vasopressors in 15. Sonographically, all patients had distended, spherical gallbladders, six had gallstones, eight had wall thickening, three had pericholecystic fluid, and four had Murphy's sign. All patients were seen by a senior abdominal surgeon, who agreed to a trial of percutaneous cholecystostomy. Fourteen patients (58%) responded to percutaneous cholecystostomy, as evidenced by a decrease in WBC count, defervescence, and the ability to be weaned off vasopressors. Bile cultures were positive in four patients. Ten patients (42%) did not respond to percutaneous cholecystostomy; five eventually died of unrelated causes. A respiratory source of infection was eventually found in three of these 10 patients, with no proved source of infection in the remainder. No complications related to catheter insertion occurred in this group of patients. Bile leaks occurred in two patients when the percutaneous cholecystostomy catheter was removed, but without serious consequence. Our experience suggests that a lower threshold for performing percutaneous cholecystostomy in this difficult clinical subset of patients is worthwhile.

Sonograms of 45 consecutive patients with histologically proven acute cholecystitis were retrospectively reviewed. The following sonographic criteria were evaluated for the presence of: thickening of the gallbladder wall; enlargement of the transverse diameter; gallbladder pressure pain (Murphy's sign); local hypoechoic areas in the bladder wall, and finally the indistinct internal appearance. All 4 patients (8.9%) with acalculous cholecystitis were detected by ultrasound. Its sensitivity as a test to detect acute cholecystitis is 88.9%, its specificity and accuracy 97.8 and 96.1%, respectively.

To determine the sensitivity of hepatobiliary imaging (HBI) and strict- and liberal-criteria real-time ultrasonography (RTUS), we retrospectively analyzed 100 cases of pathologically proved acute cholecystitis (AC). A positive HBI was one in which there was nonvisualization of the gallbladder up to four hours after the administration of technetium Tc 99m-disofenin. In the absence of hypoalbuminemia, cirrhosis, or ascites, pathognomonic RTUS findings (strict criteria) for AC were wall edema and/or pericholecystic fluid. Findings indicative of AC (liberal criteria) included the demonstration of stones, a thick gallbladder wall, nonshadowing echoes, or the ultrasonographic Murphy's sign. Of the 100 cases of AC, 91 were calculous, and nine were acalculous. Four of 100 patients had associated choledocholithiasis. The sensitivities in detecting calculous AC were as follows: HBI, 97%; liberal-criteria RTUS, 86%; and strict-criteria RTUS, 24%. The sensitivities in detecting acalculous AC were as follows: HBI, 100%; liberal-criteria RTUS, 89%; and strict-criteria RTUS, 44%.

Three children presenting with HAV hepatitis had an initial clinical onset suggestive of acute cholecystitis (pain and guarding in the right hypochondrium, fever and delayed jaundice) associated with important ultrasonographic abnormalities, also very suggestive of acute cholecystitis: bladder wall thickness greater than 10 mm (3 cases), the presence of 2 or 3 layers of different echogenicities (3 cases), presence of an ultrasonographic Murphy's sign (one case), contents of the gallbladder echogenic (one case). The authors discuss the hypothesis of an actual initial acute cholecystitis.

The Research Committee of the World Organization of Gastroenterology has gather information regarding the etiology of acute abdominal pain. Seven diseases cover 96% of the causes of this syndrome in many countries of the world, but some geographical variations have been observed. One example of these variations is amoebic liver abscess, present in 5 to 10% of Mexico City patients. Right upper quadrant pain is often present in amoebic liver abscess and acute cholecystitis. Thus, differential diagnosis of these two entities is difficult. Using discriminant analysis and "stepwise" procedures in 100 cases with cholecystitis and a similar number of patients with amoebic liver abscess, we found six variables (symptoms and signs with a significant chi square to distinguish between these two diseases. The symptoms and signs chosen were hepatomegaly, Murphy's sign, duration of pain greater than or equal to 48 hours, previous history of abdominal pain, dysentery, and facial pallor. These variables proved to be better than laboratory test results. With five of these variables it was possible to obtain an accuracy of 92%. Using six variables, if cases of tie (three variables present and three absent) were excluded, accuracy rose to 96%.

Gallbladder stones remain asymptomatic over a long period. The biliary colic is the typical pain caused by these stones. Dyspeptic symptoms seem to be unrelated to the presence of gallstones. Acute cholecystitis, a serious complication of gallstone disease, spans a wide spectrum of clinical findings. The typical signs are right upper abdominal pain and tenderness, fever, leucocytosis and Murphy's sign. 35% of patients experience gallbladder empyema or perforation. Localized gallbladder perforation, characterized by high fever, severe right upper abdominal pain and tenderness and a palpable mass is often difficult to distinguish from acute cholecystitis. Free perforation into the abdominal cavity causes diffuse peritonitis. Gallbladder perforation into the lumen of an adjacent organ produces fistulas, mostly with minimal symptoms or a pain relief after decompression of the inflamed gallbladder. Air in the bile ducts and on some occasions bile-acid-induced diarrhea may result. Rarely, the perforation of large stones leads to an occlusion of the GI tract and results in a gallstone ileus. Common bile duct stones may be asymptomatic or cause bile duct obstruction with biliary colics and jaundice. Acute bacterial cholangitis characterized by Charcot's triad (pain, jaundice and fever) and the acute biliary pancreatitis with its typical symptoms are the serious complications of common bile duct stones, associated with a high mortality rate. The clinical manifestations of a gallstone disease and its complications reveal important diagnostic features, but the most important diagnostic features, modalities are the imaging procedures. They are decisive for an accurate therapy.

The presentation of acute abdomen in elderly people differs from that in younger patients. We retrospectively assessed how the presence or absence of Murphy's sign affected initial diagnosis of acute cholecystitis in elderly patients. In the presence of Murphy's sign, diagnostic accuracy for acute cholecystitis was 80% dropping to 34% when the sign was negative. The positive predictive value of the test in elderly people was 0.58, with a sensitivity of 0.48 and a specificity of 0.79. In elderly patients, a positive Murphy's sign is useful, but a negative sign should be treated with caution and other diagnostic tests and promptly. There should be cautious interpretation of classical signs in elderly patients.

A 70-year-old woman with a past history of cholecystolithiasis was admitted to a local clinic because of right hypochondralgia with back pain. Since physical examination revealed Murphy's sign, this patient was diagnosed as acute cholecystitis. The ultrasonographic examination of the gallbladder showed a stone of the cystic duct with no definitive wall thickening. CT scan revealed dissection of the abdominal aorta. She was then referred to our hospital for further examinations. She was observed in the cardiac care unit to determine whether the aneurysm and cholecystitis were in an acute or chronic state. Blood examinations and enhanced CT scan showed that her clinical symptoms originated not from cholelithiasis but from acute closing aortic dissection, Stanford classification type B. Close cooperation with a highly developed medical facility is essential when diagnosing elderly patients with symptoms open to a variety of interpretation.

We investigated the role of Power Doppler US in the diagnosis and follow-up of cholecystitis. We reviewed the examinations of 21 surgical patients aged 27-48 years with US findings of cholecystitis. We performed B-mode and then Power Doppler US. Wall thickness and US structure, the presence/absence of stones, and US Murphy's sign were assessed at B-mode US, whereas only the presence/absence of wall vascularization was studied with Power Doppler. B-mode and Power Doppler changes post treatment were also investigated. Ultrasound showed wall thickening in all patients. In addition, positive Murphy's sign and/or gallbladder stones were seen in 6 patients each at B-mode US and wall vascularization in 7 patients with Power Doppler. Acute cholecystitis was diagnosed in these patients. The other 14 patients presenting wall thickening but no vascularization and negative US Murphy's sign were diagnosed as having chronic cholecystitis; 10 of them had gallbladder stones. Two of seven acute cholecystitis patients were operated on in the acute stage for the onset of complications and histologic findings confirmed the US diagnosis. As for the remaining patients, histology diagnosed chronic cholecystitis in 17, whereas wall thickening was not inflammatory in 2 cases. All the cases with early wall vascularization were eventually diagnosed as cholecystitis. Power Doppler US permits confirmation of the diagnosis of acute cholecystitis and distinguishing of chronic disease, which helps in planning of surgery.

A case report is presented of a 37-year-old active duty Navy petty officer with amebic abscess of the liver presenting as acute cholecystitis. He was admitted with severe right upper quadrant pain and a positive Murphy's sign, but sonogram and computed tomography (CT) scan demonstrated an abscess in the right lobe of the liver. "Anchovy paste" material was obtained on percutaneous drainage, and he was placed on metronidazole administration with a tentative diagnosis of amebic abscess. This was confirmed on enzyme-linked immunosorbent assay. Symptoms resolved within a few days, and the abscess progressively decreased in size. Amebic abscess of the liver is discussed, with emphasis on pathogenesis, diagnosis, and treatment. Although uncommon, the condition is still seen in various population groups including the United States military. Difficulty in diagnosis is not unusual, and as in the herein-reported case, amebic abscesses of the liver may be confused with acute cholecystitis and other intra-abdominal infections. Abdominal sonogram and CT examination will identify a process in the liver, but the presence of amebiasis must be confirmed by laboratory studies on serum or contents of the abscess. Amebicidal agents are effective in many cases, but there remain roles for aspiration of the abscess, percutaneous drainage, and even open surgical drainage. Failure to establish an early diagnosis may result in rupture of the abscess, with catastrophic results.
