Intraoperative ultrasonography in surgery for XXXX .

@entity1 @entity82 @entity96 @entity5 @entity1317 @entity14 @entity1575 @entity157
Intraoperative ultrasonography was used in 37 @entity1 during surgery for suspected @entity96 . The size, number, and site of the lesions were determined together with the relationship of the @entity5 to the intrahepatic vessel, as well as possible small daughter lesions within the liver. Final diagnosis in these @entity1 was @entity157 in 19 cases, metastases from @entity14 in 15 cases, and benign lesions in three cases. Previously undetected small tumors were revealed in one @entity1 with @entity5 and in five @entity1 with @entity157 who had @entity82 . Vascular tumoral infiltrations were easily displayed and the surgical approach modified accordingly: a more extended resection was performed in two cases of huge central hepatic metastases. Intraoperative ultrasonography revealed seven cases of small (2 to 3 cm) @entity157 in cirrhotic livers that were not visible or palpable, thus allowing a subsegmentary resection. Finally, in three cases of @entity5 , an intraoperative echo-guided biopsy specimen was required to establish the benign nature of lesions and resection was avoided. Intraoperative ultrasonography facilitates the diagnosis of small @entity96 and can also aid the surgeon in his choice of technique, especially in cases of @entity1575 . A resection can be avoided altogether when multiple lesions are involved, or echo-guided subsegmentary resections can be performed in cirrhotic livers when a less extended resection is required. This technique makes it possible to establish the relationship between the @entity5 and intrahepatic vessels, thus preventing @entity1317 and making radical hepatic resection safer.
