Left hepatic trisegmentectomy.

Abstract

In previous reports (1, 2), we have provided a detailed technical description of right hepatic trisegmentectomy and discussed the relation of this procedure to other more commonly used resections of the liver. At that time, the four standard kinds of anatomic liver resection were right lobectomy; right trisegmentectomy, extended right lobectomy; left lobectomy, and left lateral segmentectomy. We report herein upon a fifth procedure, left hepatic trisegmentectomy, or an extended left lobectomy, with which the true left lobe of the liver and most, or all, of the anterior segment of the right lobe have been removed in continuity.
