Abstract
BACKGROUND: Since the first laparoscopic wedge resection reported by Reich, laparoscopic liver resection (LLR) has been progressively developed, acquiring safety and feasibility. The time has witnessed a milestone leap for laparoscopic hepatectomy from pure laparoscopic partial hepatectomy to anatomical hepatectomy and from minor liver resection to major liver resection. The numerous previous studies have paid more attention to the short-time and long-time surgical outcomes caused by surgical techniques corresponding to various segments and approaches. However, focus on trocar layouts remains poorly described, but it plays an indispensable role in surgical process. METHODS: We have searched PubMed for English language articles with the key words "trocar," "laparoscopic liver resection," and "liver resection approaches." RESULTS: This review highlighted each type of trocar layouts corresponding to specific circumstances, including targeted resection segments with various approaches. Notably, surgeon preferences and patients body habitus affect the trocar layouts to some extent as well. CONCLUSIONS: Although there were fewer researches focus on trocar layouts, they determine the operation field and manipulation space and be likely to have an impact on outcomes of surgery. Therefore, further studies are warranted to firm the role of trocar layouts in LLR.
