The value of computed tomography (CT) in determining the cause of obstructive jaundice in 67 proved cases is described. The presence of stones, the level of obstruction, the relative size of the ringlike structures produced by the dilated bile duct, and the shape of the distal visualized ring have proved to be the most important variables. The retrospective analysis determined the correct cause in 94% of the cases. CT fulfills all goals considered important in obstructive jaundice and eliminates the need for invasive procedures in many cases.

A new technique for microarterial sutureless anastomosis that involves telescoping one vessel into the other and placing a microdrop of a polymeric adhesive (iso-propyl-cyanoacrylate) is described. Sixty-six anastomoses were performed in rat femoral arteries with a patency rate of 95 percent. Light and electron microscopic studies were conducted at regular intervals, starting immediately to 90 days postoperative. From this experimental study, it appears that the described method of anastomosis is faster and easier to perform and at least as reliable as the conventional end-to-end suture anastomosis. In addition, it was observed that tissue reaction to the glue remained primarily adventitial and did not disturb vessel patency.
