Considering the increasing evidence on the feasibility of laparoscopic major hepatectomies (LMH), their clinical outcomes and associated costs were herein evaluated compared to open (OMH).
Major contributors of perioperative expenses were considered. With respect to the occurrence of conversion, a primary intention-to-treat analysis including conversions in the LMH group (ITT-A) was performed. An additional per-protocol analysis excluding conversions (PP-A) was undertaken, with calculation of additional costs of conversion analysis.
One hundred forty-five LMH and 61 OMH were included (14.5% conversion rate). At the ITT-A, LMH showed lower blood loss (p < 0.001) and morbidity (global p 0.037, moderate p 0.037), shorter hospital stay (p 0.035), and a lower need for intra- and postoperative red blood cells transfusions (p < 0.001), investigations (p 0.004), and antibiotics (p 0.002). The higher intraoperative expenses (+ 32.1%, p < 0.001) were offset by postoperative savings (− 27.2%, p 0.030), resulting in a global cost-neutrality of LMH (− 7.2%, p 0.807). At the PP-A, completed LMH showed also lower severe complications (p 0.042), interventional procedures (p 0.027), and readmission rates (p 0.031), and postoperative savings increased to − 71.3% (p 0.003) resulting in a 29.9% cost advantage of completed LMH (p 0.020). However, the mean additional cost of conversion was significant.
Completed LMH exhibit a high potential treatment effect compared to OMH and are associated to significant cost savings. Despite some of these benefits may be jeopardized by conversion, a program of LMH can still provide considerable clinical benefits without cost disadvantage and appears worth to be implemented in high-volume centers.
