[Dynamic ultrasonography in the assessment of candidates to laparoscopic cholecystectomy]

Laparoscopic surgery has opened a new era in the management of surgical diseases. But, on the other hand, has created problems relating to the technological and to the technico-surgical aspects. In the preoperative evaluation of laparoscopic cholecystectomy candidates it is very important to know about the pathological state of the gallbladder, which may become the cause of very difficult or impossible laparoscopic operation, and the convert in an open procedure will be forced. Recurrent gallbladder inflammations provoke alterations of the normal structure of the wall (oedema, fibrosis) and normal elasticity and contraction after stimulation is last. Adhesion with neighbouring organs hinder contraction as well, and surgical difficulties increase. Choledocholithiasis must be known before operation, to plan surgical strategy. The presence of choledochus disease does that allow us to modify its calibre after stimulation. 100 patients who underwent laparoscopic cholecystectomy, in our Department, were evaluated before with dynamic ultrasonography (DUS), and the results were compared with operating finds. In this paper are exposed the used method of evaluation and the results of this work. These results allow as to state that the method is effective and trustworthy.
