title: Laparoscopic ultrasound staging of upper gastrointestinal tract tumors: is it really necessary?
abstract: This review describes the technique of laparoscopic ultrasound (LUS) in staging tumors of the upper gastrointestinal tract including the liver and pancreas and explores the evidence to support its role. LUS can prevent unnecessary laparotomy, particularly by detecting unsuspected focal liver lesions.
