OBJECTIVE: The aim of this study was to evaluate the accuracy of intra-operative ultrasound (IOUS) imaging in detecting liver secondaries at the time of primary colorectal surgery and to evaluate the impact of IOUS on @entity1 management. METHODS: Data from 167 @entity1 with primary @entity14 who were admitted for elective surgery between January 1995 and December 2003 were prospectively evaluated and analysed. All @entity1 underwent pre-operative abdominal ultrasonography (US) and computed tomography (CT), as well as IOUS. The final diagnosis of liver @entity3 was made by means of histological examination of either biopsy or surgical specimens. The sensitivities of pre-operative US and CT were compared with the sensitivity of IOUS, referred to histology. Changes in surgical management owing to IOUS findings were noted. RESULTS: IOUS supplied additional information in the case of 31 @entity1 . In 28 of these @entity1 , this information had a major impact on the intra-operative strategy, in that the procedure was altered. CONCLUSIONS: IOUS is safe, simple to perform and more accurate than pre-operative imaging. It reduces the number of @entity1 subjected to superfluous surgery. The use of IOUS is therefore encouraged during @entity14 surgery.
