@entity1 with @entity5 of the biliary tract have a dismal prognosis. As in most @entity5 , resection is the only effective treatment with potential for cure. Preoperative staging is not completely accurate, however, and a significant number of @entity1 with @entity1125 undergo unnecessary laparotomy. As imaging technology improves, more @entity1 with unresectable disease will be identified, avoiding the need for a laparotomy. Laparoscopy is a major addition, but its usefulness in staging of @entity5 continues to evolve. The importance of laparoscopy to better predict the resectability in @entity409 increasingly has been recognized. Conversely, the use of staging laparoscopy for other @entity5 has shown little benefit. For @entity201 and @entity1086 , the authors' analysis of 100 @entity1 supports the use of staging laparoscopy for assessing these @entity5 . In this series, staging laparoscopy correctly identified unresectable disease and prevented unnecessary laparotomy in one third of @entity1 . @entity1 with unresectable disease that was not detected at laparoscopy most often had locally advanced @entity5 . LUS did not contribute to the assessment of resectability in these @entity1 . The yield of laparoscopy was lower for @entity201 , but could be improved by targeting @entity1 who are at higher risk for occult unresectable disease, such as @entity1 with T2 or T3 lesions. These @entity1 and @entity1 with primary @entity1086 have a high incidence of @entity3 and should undergo laparoscopic staging before attempting at resection.
