Pure Laparoscopic Liver Resection for XXXX : Anatomic Resection Versus Nonanatomic Resection.

@entity1 @entity96 @entity190 @entity5 @entity260
BACKGROUND: Laparoscopic liver resection (LLR) has been considered to be safe and feasible. However, few studies focused on the comparison between the anatomic and nonanatomic LLR. Therefore, the purpose of this study was to compare the perioperative factors and outcomes of the anatomic and nonanatomic LLR, especially the area of liver parenchymal transection and @entity190 per unit area. METHODS: In this study, surgical and oncological data of @entity1 underwent pure LLR procedures for @entity96 were prospectively collected. @entity190 per unit area of liver parenchymal transection was measured and considered as an important parameter. All procedures were conducted by a single surgeon. RESULTS: During nearly 5 years, 84 @entity1 with @entity96 received a pure LLR procedure were included. Among them, 34 @entity1 received anatomic LLR and 50 received nonanatomic LLR, respectively. @entity1 of the two groups were similar in terms of demographic features and @entity5 characteristics, despite the @entity5 size was significantly larger in the anatomic LLR group than that in the nonanatomic LLR group (4.77    2.57 vs. 2.87    2.10 cm, P = 0.001). @entity1 who underwent anatomic resection had longer operation time (364.09    131.22 vs. 252.00    135.21 min, P < 0.001) but less @entity190 per unit area (7.85    7.17 vs. 14.17    10.43 ml/cm 2 , P = 0.018). Nonanatomic LLR was associated with more @entity190 when the area of parenchymal transection was equal to the anatomic LLR. No mortality occurred during the hospital stay and 30 days after the operation. Moreover, there was no difference in the incidence of @entity260 . The disease-free and overall survival rates showed no significant differences between the anatomic LLR and nonanatomic LLR groups. CONCLUSIONS: Both anatomic and nonanatomic pure LLR are safe and feasible. Measuring the area of parenchymal transection is a simple and effective method to estimate the outcomes of the liver resection surgery. @entity190 per unit area is an important parameter which is comparable between the anatomic LLR and nonanatomic LLR groups.
