[Intraoperative ultrasonography in surgery on organs of abdominal cavity and retroperitoneal space].

Since 1984 to 1999 intraoperative US examination (IOUSE) was made in 863 patients. 236 of them had diseases of the liver, 137 diseases of the gall bladder and biliary tract, 158 pancreatic disorders, 151 diseases of gastro-intestinal tract, 72 diseases of the adrenal glands, 101 constitutional obesity, 3 splenic disorders and 5 gunshot wounds of the organs of the abdominal cavity and the retroperitoneal soft tissues. In masses of the liver IOUSE showed limits for resection of the liver, location of the diseased area with the vessels and biliary ducts, unpalpablefoci. OUSE allowed to perform US-guided puncture and sclerosizing small metastatic nodes as well as a puncture and antiparasitic treatment of inaccessible echinococcal cysts. In cholelithiasis IOUSE allows to reveal or to rule out the presence of the concrements in bile ducts. In cases of diseases of the pancreas IOUSE helps to localize pathologic area, defines its interrelations with adjacent major vessels and ducts, reveals unpalpable masses and enables US-guided puncture of the major pancreatic duct followed by its further opening. In gastric tumors it is possible under US control to determine precisely the limits of the infiltration of gastric wall which defines the volume for resection. In operation on the adrenals from thoracophrenolumbar approach IOUSE through the diaphragmatic cupula determines the place and the length of phrenotomy and elucidates interrelations of the tumor with adjacent organs. Sensibility of IOUSE made up from 87 to 100%, and specificity--92-100% depending on the disease.
