Real-time ultrasonography during biliary surgery.

High resolution real-time B-mode ultrasound scanning using a sterile 7.5 MHz transducer was performed during operations on the biliary tract. Ultrasound is useful for locating the common bile duct in the presence of acute inflammation and other abnormal anatomy, detecting small calculi in the gallbladder with a thickened wall, measuring the caliber of the common bile duct, and identifying calculi in the common bile duct. Intraoperative ultrasonography can permit earlier and more precise appraisal of operative findings and, thereby, decrease operative time.

Partial splenic embolization in the treatment of hypersplenism.

Transcatheter embolization of the spleen has been associated with serious complications, such as splenic abscess, rupture of the spleen, pneumonia, and septicemia. These complications, with their grave consequences, have prevented the use of this procedure as an alternative to operative splenectomy in selected cases. A detailed description of our method, which consists of partial splenic embolization, antibiotic prophylaxis, adequate pain control, and careful pre- and postembolization, is reported. Thirteen patients with hypersplenism were successfully treated with transcatheter partial embolization of their spleen.

Percutaneous biopsy of renal transplants using ultrasonographic guidance.

The transplanted kidney is an ideal organ for study by ultrasonic methods because it is located superficially in the iliac fossa and it is free of superimposed echoes from the intestines. Therefore, it is possible to localize the transplant accurately, measure the distance from the skin to the surface of the kidney and determine with precision the angle of the intended pathway of the needle.

Skin necrosis following extravasation during peripheral phlebography.

Skin necrosis is an unusual complication following venography of the legs. The authors have found only four cases in the English literature. Two cases of skin necrosis following extravasation of contrast medium are reported. Their pathogenesis, clinical course, and treatment are discussed along with methods of prevention.

Diagnosis of urine extravasation after renal transplantation.

Urine extravasation in the early postoperative period after renal transplantation is a serious complication requiring expedient surgical intervention. Whereas clinical and laboratory findings are inconclusive, radiologic diagnostic studies have definite value. Routine ultrasound and radioisotope studies were performed on 111 renal transplant patients. In the eight who developed urine extravasation, ultrasound and/or radioisotope studies identified the extravasation in seven cases. Four of the eight were studied by intravenous pyelography and another two were studied by cystography. All results were positive. We recommend use of radioisotope and ultrasound studies for routine postoperative screening with invasive techniques reserved for inconclusive cases.

Mycobacterium bovis infection in baboons (Papio papio).

Two tuberculin-positive baboons in a primate colony were found to have grossly visible tuberculous lesions in the liver, spleen, lung, and mediastinal lymph nodes on necropsy. Results of histopathologic examination of the tissues showed granulomas with Langhans giant cells. An acid-fast organism was isolated from tissues of each baboon; the isolates were identified as Mycobacterium bovis by being negative for niacin production and nitrate reduction and by their susceptibility to thiophen-2-carbosylic acid hydrazide and to 5% glycerol.

Ultrasonically guided percutaneous aspiration of lymphoceles following renal transplantation: a diagnostic and therapeutic method.

Percutaneous aspirations of perirenal collections under ultrasonographic control is a safe and simple therapeutic and diagnostic procedure in patients who have developed lymphoceles after renal transplantation. The diagnostic and therapeutic yield is far superior to any other method, short of surgical exploration. We encountered no complications in our cases. The technique is described in detail.

Umbilical portogram in a case of Schistosomiasis japonicum.

The life cycle of shistosomes in their human host contributes to protean pathologic changes in many organs. One of these, pre-sinusoidal hepatic fibrosis in the case of S. Japonicum, was studied by an umbilical portogram during the work-up before haemofiltration. Intrahepatic portal block, with rapid tapering and marked tortuosity of portal branches as well as a very inhomogeneous and variable parenchymal pahse with poorly marginated underperfused areas and reversal of extrahepatic portal flow, was demonstrated.
