OBJECTIVE: This study was performed to evaluate the use of laparoscopic sonography in @entity1 with suspected @entity5 and to assess the impact of laparoscopic sonography on @entity1 management. SUBJECTS AND METHODS: In a prospective study, 24 @entity1 with suspected @entity9451 underwent CT, laparoscopy, and laparoscopic sonography. The pancreas, peripancreatic vasculature, liver, and porta hepatis were evaluated in each @entity1 . @entity3 (hepatic, peritoneal, or nodal), extrapancreatic extension of @entity5 , or vascular encasement was considered evidence of unresectable disease. Histopathology was the standard of reference; unresectable disease was confirmed by biopsy. At the completion of the laparoscopic sonography, each examination was scored according to impact analysis categories that had been prospectively established. RESULTS: Peripancreatic vasculature was adequately shown by laparoscopic sonography in 22 @entity1 (92%), of whom 12 @entity1 had histopathologic evidence of vascular encasement. All 12 cases of vascular encasement were revealed by laparoscopic sonography, and 10 of 12 cases of vascular encasement were revealed by CT. @entity409 were seen in eight @entity1 (33%). One @entity2695 was shown solely by laparoscopic sonography; the other seven liver lesions were revealed by CT, laparoscopy, or both. In six @entity1 (25%), laparoscopic sonography was used to guide biopsy of lesions that were not seen by laparoscopy. Impact analysis showed that laparoscopic sonography provided additional information in eight @entity1 (33%) and altered management in four @entity1 (17%). Of those @entity1 for whom laparoscopic sonography altered management, three @entity1 underwent successful resection after laparoscopic sonography two of these @entity1 had suspected vascular encasement on CT but laparoscopic sonography revealed normal vessels, and the third @entity1 had CT evidence of a liver lesion that was shown to be a cyst on laparoscopic sonography. A fourth @entity1 was spared laparotomy when laparoscopic sonography revealed unsuspected vascular encasement. CONCLUSION: Preliminary experience suggests that laparoscopic sonography may aid diagnosis and alter management in @entity1 with suspected @entity788 .
