Abstract: The following are the specifications for intraoperative sonography equipment: Small, easy-to-manipulate 7-10 mHz probes which can be gas-sterilised. The sound head contact surface should be 2 X 3 X 1 to 2 cm. Three probes of different shape. Transmission cable 2-3 m in length. Gas-sterilisable ultrasound unit, cable and plug. Large screen monitor. Control panel which can be encased with a plastic foil according to sterility requirements. 8 step gray scale. Integrated image storage. Documentation possibility us… Show more

Intraoperative echotomographic diagnosis in abdominal and neurosurgery

In many clinics, intraoperative sonography is used as a routine method in general surgery as well as in neurosurgery. The availability of sterilizable applicators in diverse shapes and sizes enables the optimal approach to the site to be examined. In processes involving the liver, the pancreas, the kidneys, or the brain, ultrasonic examination, together with an exact topographic localization, proved to be helpful in determining the dimensions of an altered structure. In patients with colorectal carcinoma, the discovery of metastases that had not been previously detected by percutaneous sonography proves the necessity of regular intraoperative ultrasonic examination to augment staging accuracy in tumor surgery.

Intraoperative ultrasound (IOUS) was performed in 21 patients with 22 endocrine tumors of the pancreas. Seventeen patients suffered from an organic hyperinsulinism, 4 had Zollinger‐EUison syndrome. One patient with an insulinoma had a pancreatic‐polypeptide‐producing adenoma (PPoma) as a second tumor. Fifteen of the insulinomas investigated by IOUS were visible and palpable. In 2 patients no tumor was found during initial operation. At reoperation 1 tumor was detected by IOUS only, the reoperation in the other patient is planned. The PPoma was an incidental finding during IOUS. In 4 patients with Zollinger‐Ellison Syndrome, 1 gastrinoma was localized in the pancreas and 2 in the duodenal wall by palpation. In 1 patient we found no gastrinoma by either surgical exploration or by IOUS. In 1 of the positive cases the tumor was demonstrable by IOUS. In the other patient it was too small for imaging. Two of these patients had liver metastases, which could be demonstrated by IOUS only. We conclude that IOUS should be performed routinely in operations for pancreatic APUDomas.

Intraoperative echo-contrast ultrasound examination of malignant liver neoplasms –initial clinical experience

et al. 1991

View full text Add to dashboard Cite

The value of intraoperative echo-contrast ultrasound (US) as compared with plain US was studied in 19 patients presenting with malignant liver tumors. The contrast medium SHU 454 was intraoperatively injected via the portal venous system or the biliary tract. Using intraoperative echo-contrast US, extremely small liver tumors could be sought in a limited area of the liver. In comparison with plain US, the former technique resulted in better demarcation of especially small tumors, which were seen as echo-poor areas in relation to the surrounding liver tissue.
