Abstract

Background: Controversy exists regarding the safety and feasibility of minimally invasive resection for lesions in segments 7 or 8. We compare outcomes of minimally invasive surgery (MIS) and Open parenchymal sparing liver resections at two high-volume centers. Methods: From 2003 to 2016 we identified patients who underwent MIS or Open resections for lesions in segments 7 or 8 at two institutions (MSKCC and SGH). Outcomes were compared using univariate and multivariate analyses. Results: Two-hundred and forty-five patients underwent resection of lesions in segments 7 or 8 (MIS 30% and Open 70%). Compared to the Open group, the MIS group had longer operative time (223 ± 88 vs 188 ± 72 minutes, P =.003), lower blood loss (297 ± 287 vs 448 ± 670 mL, P =.03), and shorter mean length of stay (5.2 ± 7.4 vs 8.3 ± 11.7 days, P <.001), which remained significant on multivariate analysis. No differences in Pringle time, rate of postoperative complications, or R0 resections were detected. Conclusions: With appropriately selected patients treated by experienced MIS hepatopancreatobiliary surgeons, MIS resection of segments 7 or 8 is safe with similar rates of complications and R0 resections, with significantly less blood loss and shorter length of stay.
