Intraoperative real-time imaging-guided laparoscopic liver resection

Abstract

In recent years, laparoscopic hepatectomy has developed rapidly, but new challenges are posed to surgeons because of this surgical approach. The disadvantages of laparoscopic surgery can be effectively solved by using intraoperative real-time imaging guidance technology. Laparoscopic ultrasound can be used to discover and diagnose the nature of lesions, mark the important pipeline structure, determine the cutting edge, and guide puncture. ICG fluorescence imaging can be applied to the identification, localization, characterization of intraoperative lesions, the marking of specific liver segments and the prevention of postoperative bile leakage. These two technologies are the only two real-time imaging guidance technologies in laparoscopic hepatectomy at present, which truly make up for the shortcomings of laparoscopic liver surgery such as the inability to palpate and limited exploration exposure. Key words: Laparoscopy; Hepatectomy; Surgery, image-guided
