Supplementary Material for: The Introduction of Laparoscopic Colorectal Surgery: Can It Improve Hospital Economics?

Introduction: Clinical benefits of laparoscopic surgery are well established, but evidence for financial benefits is limited. This study aimed to compare the financial impact of the introduction of laparoscopic colorectal surgery. Methods: This study included patients who underwent colorectal surgery between January 2010 and 2015. We collected a range of financial data and divided the patients into 2 groups. Primary outcome was total cost defined by surgical-related costs. Results: A total of 1,246 patients were included, of which 440 surgeries were performed laparoscopically. The total median cost of laparoscopy was higher compared to open surgery (EUR 4,665 vs. EUR 4,268, p = 0.001). Laparoscopy was associated with higher equipment costs (EUR 857 vs. EUR 232, p p p p p p = 0.013) for laparoscopy. Conclusion: During the introduction of laparoscopy for colorectal surgery, no significant differences were found in total cost between laparoscopic and open colorectal surgery. However, favorable postoperative outcomes were achieved with laparoscopic surgery.引言：腹腔镜手术的临床益处已得到充分证实，但关于其财务收益的相关证据仍较为有限。本研究旨在对比腹腔镜结直肠手术推广应用所带来的财务影响。 方法：本研究纳入2010年1月至2015年1月期间接受结直肠手术的患者。我们收集了多维度财务数据，并将患者分为两组。本研究的主要结局指标为以手术相关成本界定的总治疗成本。 结果：本研究共纳入1246例患者，其中440例接受了腹腔镜手术。腹腔镜手术的总中位成本高于开放手术（4665欧元 vs 4268欧元，p=0.001）。腹腔镜手术的设备成本显著更高（857欧元 vs 232欧元，p=0.013）。 结论：在腹腔镜结直肠手术引入阶段，腹腔镜与开放结直肠手术的总治疗成本并无显著差异。然而，腹腔镜手术可获得更优异的术后结局。
