Hepatic abscess following biliary tract surgery. Etiology, treatment and results.

Experience of seven consecutive cases of liver abscess following biliary tract surgery is presented. The age range was 41-83 years, and six of the patients were women. The interval from operation to appearance of abscess was 10 days to 14 months. Primary surgical drainage was used in two patients, who remained clinically well 6 months and 2 years later. Four of five patients with initially percutaneous drainage subsequently underwent operative drainage, but one refused further surgery and died 8 days later of sepsis. Multiple factors may predispose to both cholangitis and hepatic abscess following biliary tract surgery. Radiologic investigation of abscess must also focus on identifying underlying biliary pathology. Bactericholia and obstructed bile flow are two of the most important etiologic factors in hepatic abscess after biliary surgery. Experience with these cases suggests that a surgical approach may be preferable to percutaneous techniques in management also of the associated biliary pathology.

Kerr-McGee and the NRC: from Indian country to Silkwood to Gore.

By focusing upon the Nuclear Regulatory Commission's appraisal of the Kerr-McGee Corporation's safety record in the Four Corners area and at two facilities in Oklahoma, this article examines the political economy of nuclear regulation in American society. Particular attention is given to the agency's response to intervenor groups which protested various operations at Kerr-McGee facility in Gore, Oklahoma, both prior to and following the accidental rupture of a cylinder containing uranium hexafluoride. Despite a consistent record of violations and nuclear mishaps by Kerr-McGee, the Nuclear Regulatory Commission permitted the company to essentially monitor its own activities. Rather than protecting workers and the public from the hazards of the nuclear industry, state regulation attempts to legitimize and defuse public opposition to its endeavors.

Preautopsy magnetic resonance imaging: initial experience.

To our knowledge, there are no prospective data in the literature investigating the role of magnetic resonance imaging (MRI) in detecting abnormalities in cadavers to determine the feasibility of this concept. We prospectively studied six cadavers (three stillborn infants, one infant, and two adults) with a 0.15 T resistive magnet. The images obtained allowed detection of abnormalities in multiple organs. Although autopsy was superior to MRI in detecting very small abnormalities, MRI was equal to autopsy in detecting gross cranial, pulmonary, abdominal, and vascular pathology in this small series. In addition, MRI was superior to autopsy in detecting air and fluid in potential body spaces. Preautopsy MRI may be an alternate method in restricted or denied autopsies and may provide an additional MRI research and educational tool.

Multiple tumors of the biliary tract.

Multiple synchronous tumors of the extrahepatic biliary tree are not frequently reported. Over a 2-year period, 54 operative procedures were performed for tumors of the extrahepatic biliary tract or periampullary region. In five of these cases, unsuspected tumors were observed. Of these, one patient had multiple benign papillomatosis of the extrahepatic biliary tree. All four of the other patients were found to have unsuspected small carcinomas of the gallbladder in association with mid- or low bile duct cancer. Multiple tumors of the extrahepatic biliary apparatus may occur more frequently than previously thought, and the incidence of unsuspected gallbladder cancer in association with bile duct cancer may be high. These tumors should be suspected and looked for in each instance by intraoperative endoscopy and careful histologic examination of the gallbladder.
