Case reports of benign hepatoma in young women taking oral contraceptives (OCs) are known to exist. A benign hepatic adenoma was discovered in a young woman who had been taking an OC (Ortho-Novum 2) for 7 years. Although hepatic adenoma is a rare tumor, the increasing number of reports of its occurrence strongly suggest an association between OCs and benign hepatic adenoma. Diagnosis must be suspected in any young woman taking OCs and developing signs of acute cholecystitis with hepatomegaly or mass, or presenting with signs and symptoms of nontraumatic intraabdominal hemorrage. Rupture of the tumor is life-threatening. Treatment should be removal of the tumor whenever possible.

Two adults had the hypovascular nature of their hepatic abscesses ascertained by total body opacification. In one, total body opacification identified the hypovascular nature of the lesion, facilitating its differentiation from vascular hepatoma. In the other, the clinical diagnosis was acute cholecystitis with empyema of the gallbladder, and the liver was normal to inspection and palpation at celiotomy. Total body opacification may be helpful in the examination of abdominal masses.

Management of recurrent hepatocellular carcinoma in a cirrhotic liver remnant is a difficult but challenging problem. To investigate the difference in survival between treatment by repeat resection and treatment by transcatheter arterial chemoembolization (TAE), a retrospective controlled study was conducted. Four patients with nodular recurrence received limited second operations which included right hepatic segmentectomy (2 patients), left lateral segmentectomy (1 patient), and subsegmental wedge resection (1 patient). Eight matched patients received a total of 16 repeated sessions of chemoembolizations. Complications of the TAE group consisted of gastrointestinal bleeding (2 patients), acute pancreatitis (1 patient), and acute cholecystitis (1 patient). No complication developed in the resection group. The 4 patients undergoing a second operation have survived 21, 26, 34, and 54 months after repeat surgery. Seven (87.5%) of the 8 patients receiving TAE died 4 to 11 months after TAE. The resection group survived significantly longer than the TAE group (p < 0.01). Our results suggest that it is more advisable to perform a second operation than to undertake chemoembolizations for patients with cirrhosis and nodular recurrent hepatocellular carcinoma with acceptable functional liver reserve.

Selected papers published over the past year in the areas of radionuclide hepatobiliary imaging, gastric emptying, and gastrointestinal bleeding are reviewed. Two advances in cholescintigraphy are particularly emphasized and discussed. First, morphine-augmented cholescintigraphy has established itself as an accurate alternative to 2 to 4 hour delayed imaging for the diagnosis of acute cholecystitis. Second, sincalide-stimulated cholescintigraphy with calculation of a gallbladder ejection fraction has proven to be a useful test for confirming the clinical diagnosis of chronic acalculous cholecystitis. Other hepatobiliary papers reviewed include those on the utility of cholescintigraphy in gallbladder perforation, hepatocellular carcinoma, liver transplantation, enterogastric reflux, and for the diagnosis of the postoperative complications of laparoscopic cholecystectomy and gallstone lithotripsy. The second major area of review includes papers published over the past year on gastric emptying, including investigations of methodology, physiology and pathophysiology, and clinical utility. A few papers utilizing radionuclide techniques for localizing gastrointestinal bleeding will also be reviewed.

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.

Prominent periportal echogenicity was detected during sonographic examination of patients suffering from recurrent pyogenic cholangitis, hepatocellular carcinoma and acute cholecystitis. To document the finding, 140 normal individuals were studied to establish a norm for the evaluation of the periportal echogenicity. The significance of this sonographic finding and its possible aetiology are discussed.

Many imaging techniques can be used to assess the liver and hepatobiliary system. Each modality has individual strengths and limitations, which usually vary depending on the specific clinical situation. This review discusses several specific common clinical situations where imaging of the liver and biliary system is necessary and describes the various imaging options. Space-occupying liver lesions are discussed, and particular attention is paid to the assessment of liver metastasis, hepatoma, and incidentally discovered liver lesions such as hemangioma, adenoma, and focal nodular hyperplasia. The value of ultrasound, computed tomography, magnetic resonance imaging, and scintigraphic techniques in this patient population is described. Isolated sulfur colloid hepatic scintigraphy is not of great value in the evaluation of these patients. Therefore, this review describes in some detail the value of physiological liver scintigraphy, including gallium and iminodiacetic acid (IDA) scanning as well as dynamic flow imaging of the liver such as hepatic artery perfusion scintigraphy and tagged red cell scintigraphy. Imaging of the biliary tree also is described. The roles of ultrasound and scintigraphy are compared and contrasted as related to the diagnosis of acute cholecystitis, common duct obstruction, and postoperative complications.

A hepatobiliary scan was performed on a patient presenting with symptoms of acute cholecystitis. In addition to cystic duct obstruction, there was a focal area of intense uptake in the left lobe of the liver. Additional imaging studies confirmed a solid mass in the left lobe of the liver, which proved to be a hepatocellular carcinoma on surgery.

A case of acute abdomen presenting with pain in the right upper abdomen, pyrexia and leukocytosis is presented. At laparotomy, hepatocarcinoma with necrosis and associated acute cholecystitis was found. This is apparently an unusual report of hepatocarcinoma presenting as acute cholecystitis.

Acute cholecystitis due to Campylobacter fetus subsp. fetus is very uncommon. We report a case of cholecystitis and obstructive jaundice in which cultured bile grew this organism. The patient had a 4-year history of hepatocellular carcinoma, resulting in common bile duct obstruction due to abdominal lymph node metastasis. Microscopic examination of her bile showed multiple Gram-negative curved organisms and C. fetus subsp. fetus was isolated under microaerophilic conditions. Therefore, we should be aware of this organism and use microaerophilic culture in association with the result of microscopic examination of bile specimens.
