“…The sensitivity ranges from 84% to 98% and the specificity ranges from 90% to 99%. [12][13][14][15][16][17][18][19][20][21][22][23] The sonographic Murphy's sign was chosen to be the focus of the BAU examination for acute cholecystitis because it is one of the most sensitive indicators of acute cholecystitis and is technically simple to elicit. The definition of the sonographic Murphy's (positive when the site of maximal tenderness corresponded to the location of the gallbladder determined by the US transducer) we used has been described in the radiologic literature.…”

“…Intravenous cholangiography has been found to have a 40 per cent technical failure rate (gallbladder and bile ducts not seen) in 220 patients with of severe side effects. Ultrasound demands a considerable amount of expertise and time; we had two technical failures (gallbladder not identified) and others have experienced failure rates of between 3 and 20 per cent (16, [19][20][21][22]. Infusion cholecystography has been shown to be unreliable; in one series of 27 patients a diagnosis of gangrenous cholecystitis was missed (19).…”

A series of 105 patients with upper abdominal pain suggestive of biliary colic who had hepatobiliary scans within 48 h of admission to hospital is presented. Fifty of the 65 patients with abnormal scans had operative treatment and gallbladder pathology was found in every case. Fourteen of these patients had hepatobiliary scans which also showed delayed excretion of tracer into the duodenum, and of these, 12 were found to have common bile duct stones and one a stricture of the distal end of the common bile duct. Of the 40 patients who had normal scans, 7 were found to have gallstones on further investigation. In these patients abnormal hepatobiliary scans have shown a 100 per cent correlation with gallbladder disease. We suggest that this is the investigation of choice for the surgeon contemplating early cholecystectomy on patients with suspected acute gallbladder disease.

“…All our patients were scanned by a single consultant radiologist who has not only devised an individual technique for outlining the biliary tract, but has also been routinely scanning patients with gallstone disease and acute pancreatitis for several years (McKay et al, 1977;McKay et al, 1978). It is of interest that some erroneous reports have arisen in our own hospital, when the scanning was performed by a less experienced person.…”

Sixty-seven patients were prospectively studied using grey scale ultrasound (GSU) to assess its possible role as part of a jaundice investigation programme. All scans were performed by one radiologist, without clinical information. When intrahepatic ductal dilatation was found an attempt was made to establish the level and cause of obstruction. The calibre of the intrahepatic bile ducts was correctly reported in 66 patients (98 per cent). Forty-three proved to have extrahepatic cholestasis, 24 had intrahepatic cholestasis. No patient with intrahepatic cholestasis had dilated ducts seen on ultrasound. In 43 patients with obstructive jaundice, GSU accurately detected the level of obstruction in 28. This accuracy varied with the cause of obstruction. A direct indication of diagnosis was possible in 45 of the 67 patients. In a unit specializing in the management of complicated hepatobiliary problems, GSU has been shown to be accurate in differentiating extra- from intrahepatic jaundice. Being non-invasive, it appears ideally suited for use as a screening procedure, permitting selection of appropriate invasive investigations to provide complete preoperative imaging of the biliary tree. In patients with jaundice due to gallstones, GSU may be the only imaging technique required before surgery provided good operative cholangiography is available.
