Laparoscopic ultrasonography for abdominal tumor staging: technical aspects and imaging findings

Abstract

Since 1992 diagnostic laparoscopy combined with laparoscopic ultrasonography has been performed in our center in more than 300 patients for staging of tumors of the liver, bile ducts, pancreas, esophagus, and gastric cardia. In this article our experience with laparoscopic ultrasonography for abdominal tumor staging is described, with particular attention for the technical aspects, imaging findings, limitations, and pitfalls.
