Ultrasound evaluation of cholelithiasis in the morbidly obese.

The ability to detect gallstones in the morbidly obese population has been questioned in recent literature. Utilizing state-of-the-art, real-time ultrasound equipment, 44 morbidly obese patients were examined prior to gastric exclusion surgery and concomitant cholecystectomy. The 91% sensitivity and 100% specificity of gallstone detection in this series matches the results for the general population.

Delayed sternal closure following open-heart operation.

Between June, 1976, and December, 1980, 29 patients underwent delayed sternal closure at the Newark Beth Israel Medical Center. The indications were enlarged heart with tamponade when the mediastinum was closed, poor lung compliance, hemodynamic instability due to intractable arrhythmias or coagulopathy, and presence of a mediastinal assist device. Following an open-heart procedure, the retrosternal space may no longer accommodate the heart and approximation of the sternum will produce hypotension and elevation of right and left end-diastolic pressures.
