Computed tomographic evaluation of the excluded stomach in gastric bypass.

Eleven patients who had gastric bypass operations were examined with computed tomography to evaluate the status of the excluded stomach. Three of the patients had dilated excluded stomachs that accounted for the patients' symptomatology. As an upper gastrointestinal series cannot delineate the excluded stomach, computed tomography is the examination of choice for such an evaluation.

The spectrum of computed tomographic appearance of metastatic masses from testicular neoplasms.

Metastatic masses from testicular neoplasms were evaluated with respect to their computed tomographic characteristics. They were divided in three categories: cystic, semicystic, and solid. The common denominator in the first two categories was the presence of teratomatous components. The nonteratomatous masses were solid.
