OBJECTIVE: To define the role of laparoscopic ultrasound (LUS) in the staging of @entity788 . SUMMARY BACKGROUND DATA: Laparoscopy has recently been established as a valuable tool in the staging of @entity788 . It has been suggested that the addition of LUS to standard laparoscopy could improve the accuracy of this procedure. METHODS: A prospective evaluation of 90 @entity1 with @entity788 undergoing laparoscopy and LUS was performed over a 27-month period. LUS equipped with an articulated curved and linear array transducer (6 to 10 MHz) was used. All @entity1 underwent rigorous laparoscopic examination. Clinical, surgical, and pathologic data were collected. RESULTS: The median age was 65 years (range 43 to 85 years). Sixty-four @entity1 had @entity5 in the head, 19 in the body, and 3 in the tail of the pancreas. Four @entity1 had @entity5 . LUS was able to image the @entity5 (98%), portal vein (97%), superior mesenteric vein (94%), hepatic artery (93%), and superior mesenteric artery (93%) in these @entity1 . LUS was particularly helpful in determining venous involvement (42%) and arterial involvement (38%) by the @entity5 . This resulted in a change in surgical treatment for 13 (14%) of the 90 @entity1 in whom standard laparoscopic examination was equivocal. CONCLUSIONS: LUS is useful in evaluating the @entity5 and peripancreatic vascular anatomy. When standard laparoscopic findings are equivocal, LUS allowed accurate determination of resectability. Supplementing laparoscopy with LUS offers improved assessment and preoperative staging of @entity788 .
