[The European liver surgery topic--recent developments in liver surgery (in situ protection and ex situ operation)].

Ex situ operations on the liver, a new surgical approach, and operations on a vascularly isolated and in situ hypothermic-perfused liver were performed in 12 patients. The indications for either approach were limited to patients for whom a conventional approach was impossible or seemed insufficiently radical. In one case a huge symptomatic focal nodular hyperplasia in segment IV became resectable only with the ex situ-technique. Our first experience showed that preoperative cholestasis is a high-risk factor for postoperative hepatic insufficiency; three patients with marked preoperative cholestasis died. In patients with good preoperative liver function these two approaches allow a more radical liver resection and are the only possibility for tumor resection in particular situations.
