A prospective study to evaluate the accuracy of early diagnosis and the efficacy of early operation for biliary tract stone disease was performed. One hundred fifty-two consecutive patients with signs and symptoms compatible with biliary colic or acute cholecystitis were admitted to the hospital and promptly evaluated with ultrasonography and hepatobiliary (Pipida) scanning. Patients with demonstrable stones or a nonvisualized gallbladder underwent operation within 48 hours of admission. Of 75 patients who underwent operation, 64 had acute and/or severe chronic cholecystitis. Associated biliary pancreatitis was present in 14 of 75 patients. Cholecystectomy with intraoperative cholangiography was performed for 73 of the 75 patients. One patient underwent cholecystectomy only and one patient underwent cholecystostomy. There were 18 common duct explorations. No transfusions were required and there were no deaths. The average duration of hospital stay for all patients who underwent operation was 6.5 days. The results indicate that an accurate diagnosis of acute biliary tract stone disease can be made rapidly with use of sonography and hepatobiliary scanning, that cholecystectomy with intraoperative cholangiography and common duct exploration as necessary can be performed safely (including cases of biliary pancreatitis) in the acute setting, and that with early operation the duration of stay is decreased and morbidity and mortality rates compare favorably with those of elective cholecystectomy. It is concluded that operation performed within at least 48 hours of admission is the treatment of choice for acute biliary tract stone disease.

Comparative examination of the material obtained from 133 cadavers of patients dying after operations for chronic pancreatitis, pancreonecrosis, and cholecystitis as well as dying suddenly with other diseases (control) was carried out. Stereoscopic microscopy was used to study the internal relief of the mucous membrane of the ampulla and ducts of the major duodenal papilla (MDP), and their step-wise histological examination was performed. From 1 to 10 valves were found in 98% of the control cases. Inflammatory diseases of the gall bladder and pancreas were found to be accompanied by morphological changes in the valve apparatus of MDP. In acute cholecystitis and pancreatitis, edema of the valves and their inflammatory infiltration developed. Courvoisier's gallbladder and chronic recurrent pancreatitis with the duration of the disease up to 3 years resulted in hypertrophic changes in the valves. A disease of longer duration (from 3 to 7 years) was accompanied by deforming changes in the valves with possible subsequent complete atrophy of the valvular apparatus.

Hepatobiliary imaging with the various technetium-labeled IDA compounds is more than 90% sensitive and specific for the diagnosis of acute cholecystitis. Causes of false-positive studies include chronic cholecystitis, cystic-duct obstruction by tumor, prolonged fasting, the nonfasting state, pancreatitis, alcoholism, parenteral hyperalimentation, and severe intercurrent illness. A case of congenital absence of the gallbladder is submitted as another cause of a false-positive scan.

The recent availability of iminodiacetic acid analogues labeled with technetium Tc 99m provides a safe and accurate noninvasive test of biliary function. Biliary scintigraphy is a simple and rapid method of detecting acute cholecystitis in particular but also of distinguishing acute biliary pancreatitis from nonbiliary pancreatitis, of evaluating the patency of the common duct in early obstruction, of assessing possible postcholecystectomy syndrome, of evaluating the patency of a biliary enteric bypass, and of detecting postoperative biliary leaks.

Radiographs taken on the day of admission on 52 patients with acute pancreatitis have been compared with similar radiographs of 30 patients with acute cholecystitis and 22 patients with perforated duodenal ulcer. Two radiologists, who were unaware of the clinical features, looked specifically for the presence of 30 radiological signs. The only abdominal signs seen more frequently in acute pancreatitis were fluid levels in the stomach and duodenum, usually associated with dilatation. Duodenal abnormalities were seen in 42% of patients with acute pancreatitis and 21% of the controls (P less than 0.05) while gastric dilatation with a fluid level was seen in 29% of cases of acute pancreatitis compared with 12% of controls (P less than 0.05). Seventy per cent of the patients with severe acute pancreatitis had an abnormal chest radiograph on admission compared with 18% of those with mild disease. Left pleural effusion was the most common abnormality in severe pancreatitis (43%) and was seen significantly more often than in mild pancreatitis (P less than 0.01) and the control group (P less than 0.05). Therefore, consideration of the admission chest radiograph may help at an early stage to distinguish patients with severe pancreatitis from those with mild disease.

Early surgery for biliary pancreatitis has resulted in a need for an accurate method of gallstone detection in acute pancreatitis. Fifty patients with acute pancreatitis were studied prospectively to assess the diagnostic value of Radionuclide Biliary Scanning (RBS) performed within 72 hours of an attack. To assess the general accuracy of RBS a further 154 patients with suspected acute cholecystitis or biliary colic were similarly studied. There were 34 patients with biliary pancreatitis and 18 (53%) had a positive scan (no gallbladder seen). There were 16 patients with non-biliary pancreatitis and 5 (31%) had a positive scan. All 51 patients with acute cholecystitis had a positive scan, as did 82% of the 51 patients with biliary colic. There were 52 patients with no biliary or pancreatic disease and none of these had a positive scan. RBS is highly accurate in confirming a diagnosis of acute cholecystitis or biliary colic. However, it cannot be relied on to differentiate between biliary and non-biliary pancreatitis and should certainly not be used as the basis for biliary surgery in these patients.

Thirty-five patients with acute nonbiliary pancreatitis were studied with 99m-Technetium para isoproply iminodiacetic acid in order to determine its ability to differentiate acute nonbiliary pancreatitis from acute cholecystitis. Of acute nonbiliary pancreatitis patients 90.3% (28/31) visualized their gallbladder in 1 h, 9.7% (3/31) had delayed visualization of gallbladder, and no patient in this category failed to visualize their gallbladder. Two of four patients with acute episodes of pancreatitis superimposed on chronic pancreatitis visualized their gallbladder. Biliary scintigraphy remains to be a valuable tool in differentiating acute nonbiliary pancreatitis from acute cholecystitis.

Perforation of the gallbladder is a life-threatening complication of acute cholecystitis that is often difficult to diagnose at an early stage. Standard radiographic and laboratory tests have not been reliable in identifying patients with this complication. In contrast, biliary sonography correctly diagnosed pericholecystic abscesses preoperatively in three patients with acute cholecystitis. The ultrasonic appearance of acute cholecystitis with a pericholecystic abscess was similar in all three patients. There was an extraluminal fluid collection located contiguous to a thick-walled gallbladder in the fundic region. The fluid collection was constant in location and could be seen in at least two different views. Two of these three patients had acalculous cholecystitis; the initial clinical diagnosis in one was pancreatitis, and in the other alcoholic hepatitis. Biliary sonography, by demonstrating a thickened gallbladder wall in the absence of ascites, strongly suggested that these two patients had acute acalculous cholecystitis, and not hepatitis or pancreatitis. The ultrasonic examination was a critical factor in the decision for prompt surgery instead of continued nonoperative management in these patients. These data suggest that not only can biliary sonography aid in the diagnosis of acute cholecystitis, calculous as well as acalculous, but can also visualize a pericholecystic abscess when it is present.

Cholescintigraphy with technetium-labeled biliary agents has great value in evaluation of the patient with suspected acute cholecystitis. Visualization of the gall bladder virtually excludes acute cholecystitis and obstruction of the cystic duct. Nonvisualization of the gall bladder, however, is not specific for acute cholecystitis and may also occur in some patients with chronic cholecystitis or pancreatitis. Interpretation of gall bladder nonvisualization, therefore, must be correlated with the clinical presentation. Biliary tract imaging is also useful in evaluation of some focal abnormalities within the liver, neonatal jaundice, detection of bile leaks or bile reflux, and biliary-enteric shunts. The role of technetium-labeled biliary agents in the evaluation of patients with jaundice is less clear. Excretion of tracer into the gut excludes complete biliary tract obstruction, but the test may be nonconclusive at higher serum bilirubin levels. If persistent common bile duct activity is observed with delayed excretion into the gut, the diagnosis of partial obstruction may be made, but this procedure will be inconclusive if the common bile duct is not visualized and/or significant hepatocellular disease is present. Ultrasonography and abdominal CT are the preferred tools for the diagnosis of biliary tract obstruction at present, but newer biliary tract agents which achieve better hepatic extraction and greater bile concentration at high serum bilirubin levels may improve the diagnostic efficacy of cholescintigraphy.

A 40-year-old woman presented with acute epigastric pain with vomiting. Within 24 hours, the pain spread to the right periumbilical region. Tc-99m disofenin hepatobiliary scan failed to demonstrate the gallbladder on a 60-minute view. The presumative diagnosis of acute cholecystitis was thought to be confirmed on this basis by the patient's physicians. However, a 75-minute view demonstrated filling of the gallbladder. In hepatobiliary scanning for acute abdominal pain, delayed views (2 to 24 hours) are recommended when the gallbladder is not visualized on the 60-minute view. If the gallbladder is visualized, cystic duct obstruction can be excluded and diagnoses such as pancreatitis, acalculous cholecystitis, and acute appendicitis should be investigated.
