BACKGROUND: Blunt-clamp dissection allows for visualization of intrahepatic vessels and individual ligation of major blood or bile vessels. Recently, many instruments have been developed for precoagulation of liver parenchyma before sharp transection, but suffer from the possibility of injuring major blood and biliary vessels that are not well-visualized, along with high cost. In this article, we describe a postcoagulation technique combining clamp dissection and sealing of vessels under direct vision using a tissue-sealing device. STUDY DESIGN: Clinical evaluation of 400 patients from 2 centers subjected to liver resection using this technique. RESULTS: There were no cases complicated by hemorrhage. There was an incidence of 1.8% for bile leaks. This low incidence of biloma formation was seen even with the high incidence (49%) of abnormal parenchyma encountered in this cohort. CONCLUSIONS: Combining the clamp-crushing method with use of the LigaSure device (Valleylab) allows identification of intraparenchymal vessels followed by sealing. This method of parenchymal transaction optimizes ease of use with confidence in vessel ligation. (J Am Coll Surg 2010;210: 39-44. (C) 2010 by the American College of Surgeons)
