Four patients with acquired immunodeficiency syndrome developed severe abdominal pain and fever due to acute acalculous cholecystitis. In all patients, preoperative laboratory data showed elevation of alkaline phosphatase and gamma-glutamyltransferase levels. Endoscopic or intraoperative cholangiography showed signs of intrahepatic and extrahepatic cholangitis. Cholecystectomy was performed and prompt relief of symptoms was achieved in all patients; no postoperative complication was observed. One patient did not develop any recurrence during an 18-month period of follow-up; two patients died 2 and 3 months after the operation. One patient developed recurrent abdominal pain and cholestasis 4 months after the operation, with dilatation of the common bile duct and papillary stenosis due to progression of cholangitis. These observations suggest that cholangitis is frequently associated with cholecystitis in patients with the acquired immunodeficiency syndrome. Its pathogenesis is not known.

The objective of the study was to investigate the accuracy of using preoperative data for the prediction of bile duct calculi in patients operated on for acute cholecystitis. 279 consecutive patients underwent cholecystectomy with peroperative cholangiography for acute calculous cholecystitis in the Department of Surgery, Lund University Hospital, between 1985 and 1991. The correlation between 13 preoperative clinical and laboratory variables, and the incidence of bile duct calculi was studied. Among the 13 variables tested, serum bilirubin concentration and serum gamma-glutamyltransferase activity were independent factors of predictive significance. These two factors were used for constructing an additive prognostic index for the presence of bile duct stones. Thus, three groups of patients could be identified having a 3, 7-9 or 59% risk of harboring bile duct stones, corresponding to a sensitivity of 61% and a specificity of 93% in predicting the presence of bile duct stones in the 'high-risk' group. Logistic regression analysis permits accurate preoperative identification of bile duct stones in patients with acute calculous cholecystitis.

A number of pitfalls can be encountered in the interpretation of common blood liver function tests. These tests can be normal in patients with chronic hepatitis or cirrhosis. The normal range for aminotransferase levels is slightly higher in males, nonwhites and obese persons. Severe alcoholic hepatitis is sometimes confused with cholecystitis or cholangitis. Conversely, patients who present soon after passing common bile duct stones can be misdiagnosed with acute hepatitis because aminotransferase levels often rise immediately, but alkaline phosphatase and gamma-glutamyltransferase levels do not become elevated for several days. Asymptomatic patients with isolated, mild elevation of either the unconjugated bilirubin or the gamma-glutamyltransferase value usually do not have liver disease and generally do not require extensive evaluation. Overall hepatic function can be assessed by applying the values for albumin, bilirubin and prothrombin time in the modified Child-Turcotte grading system.

Percutaneous ultrasound-guided cholecystocentesis was performed on 13 healthy beagle dogs to determine whether percutaneous ultrasound-guided cholecystocentesis in the dog was a feasible and safe procedure. Clinical, laboratory and ultrasonographic examinations were done at 0 and 10 minutes, in the 2nd and 16th hour, and on the 7th day. They included a detailed physical examination of the mucous membranes, cardiorespiratory system and abdominal organs. Laboratory examinations of the blood consisted of a complete blood count, determination of packed cell volume (PCV), haemoglobin (Hb), total plasma protein (TPP), parameters of haemostasis including prothrombin time (PT), activated partial thromboplastin time (APTT), and enzyme activities reflecting hepatobiliary function, i.e. aspartate aminotransferase (AST), alanine aminotransferase (ALT), and gamma-glutamyltransferase (GGT). Ultrasonographic findings of the gallbladder (size, shape, wall, content) and appearance of the biliary tract and the surrounding cranial intraabdominal organs were also evaluated. Percutaneous ultrasound-guided cholecystocentesis was performed easily during the study, and dogs tolerated well the procedure performed without anaesthesia. All laboratory parameters of the blood remained within normal limits throughout the study. However, some follow-up values, i.e. PCV, TPP, APTT and ALT, demonstrated statistically significant differences when compared to baseline measurements, which might reflect the effect of 24-hour fasting before the experiment, as well as day-to-day metabolic fluctuations due to feeding and water supply during the study. There were no visible signs of bleeding from the liver, bile leakage from the gallbladder or accumulation of free peritoneal fluid during repeated ultrasonographic examinations. Percutaneous ultrasound-guided cholecystocentesis seems to be an important diagnostic procedure in canine gallbladder diseases and can be used safely and easily to gain gallbladder bile for diagnosis of bacterial cholecystitis or for investigating hepatobiliary function in the dog.
