Abstract

Purpose: The aim of this study was to compare the clinical outcomes between laparoscopic partial liver resection and open partial hepatectomy for tumors in the posterosuperior segments. Methods: The clinical outcomes of patients who underwent either laparoscopic (n = 20) or open (n = 44) resection in segments 7/8 of the liver were initially evaluated. Because of disparities in the background characteristics, a case-matched study (1:1) was conducted. In addition, a comparative study of the patients who met the institutional criteria for laparoscopic partial hepatectomy was performed. Results: In the case-matched study, the laparoscopic technique required a longer operation time (p = 0.001), but was associated with less intraoperative blood loss (p = 0.021), a lower incidence of major complications (p = 0.014), higher levels of serum albumin on postoperative days 3 and 7 (p = 0.031 and p = 0.035), and earlier discharge (p = 0.001) than open resection. The results of the latter study were similar to those of the case-matched analysis. Conclusions: Laparoscopic partial hepatectomy was a feasible procedure for treating tumors in the posterosuperior segments without compromising oncological safety and yielded better short-term outcomes than open techniques. In addition, this study provides concrete selection criteria for laparoscopic partial hepatectomy for difficult lesions.
