Insulinoma in a patient with annular pancreas.

Intraoperative ultrasonography has facilitated the localization of insulinomas. In this report, we describe a patient who was found to have an insulinoma in association with an annular pancreas. Because such tumors can be in close approximation to major pancreatic ductal structures, intraoperative ultrasonography can be useful for not only localizing the lesion but also delineating the related anatomic features. Although the optimal management of an asymptomatic annular pancreas has not been determined, our patient had no evidence of chronic pancreatitis and no narrowing of the duodenal lumen; therefore, no bowel bypass procedure was done.

Computed tomography and peritoneoscopy for detection of liver metastases: review of Mayo Clinic experience.

The effectiveness of computed tomography (CT) and peritoneoscopy in detecting liver metastasis was studied by review of 97 cases in which both of these procedures and also biopsy or autopsy were performed. Tissue examinations disclosed hepatic lesions in 45 cases. The sensitivity of CT and peritoneoscopy was 89 and 62%, respectively; and their specificity 94 and 96%. In 35% of biopsy-proven cases, CT detected lesions not visible at peritoneoscopy; and in 7% peritoneoscopy revealed lesions not shown by CT. The difference resulted from the more frequent occurrence of liver metastases in locations more suitable for CT detection. The results suggest that CT should be tried before peritoneoscopy (other considerations being equal), and that CT guidance for biopsy deserves more frequent use. The reliability of negative CT or peritoneoscopy findings remains uncertain, since autopsy has been obtained in only 3 of the 52 negative cases.

Malformation of bronchopulmonary foregut with systemic and pulmonary arterial blood supply.

A case of congenital malformation of the bronchopulmonary foregut with communication between the esophagus and sequestered lobe is reported in a six-month-old boy. Only 29 similar cases have been reported previously, and this case was especially unusual in that the communication was from the middle portion of the esophagus to a right apical sequestration. Another unusual feature was that the sequestered segment was supplied by four systemic arteries from the thoracic aorta, as well as by branches from the right pulmonary artery. Within the sequestration, there was shunting of blood from the systemic to pulmonary arterties with reversal of flow in the pulmonary arterial branches.
