The aim of this study was to estimate the effect that the expansion of laparoscopic surgery has had on global warming. Laparoscopic procedures performed in a hospital over a 10-year period were analysed. The number of CO(2) cylinders (size C) used over a 2.5-year period and the "carbon footprint" of each cylinder was calculated. There was a fourfold increase of in the number of laparoscopic procedures performed over the past 10 years (n = 174-688). Median operative time for the laparoscopic procedures performed over the past 2.5-years (n = 1629) was 1.01 h (range 0.3-4.45 h) with 415 cylinders used in this period giving an operative time per cylinder of 3.96 h. Each cylinder produces only 0.0009 of tonnes of CO(2). Despite increasing frequency of the laparoscopic approach in general surgery, its impact on global warming is negligible.
本研究的目的是评估腹腔镜手术的扩展对全球变暖产生的影响。分析了一家医院在10年期间实施的腹腔镜手术。计算了2.5年期间使用的CO₂气瓶（C型）数量以及每个气瓶的“碳足迹”。在过去10年中，腹腔镜手术的实施数量增加了四倍（从174例增至688例）。过去2.5年实施的腹腔镜手术（n = 1629）的中位手术时间为1.01小时（范围0.3 - 4.45小时），在此期间使用了415个气瓶，每个气瓶的手术时间为3.96小时。每个气瓶仅产生0.0009吨CO₂。尽管普通外科中腹腔镜手术的频率在增加，但其对全球变暖的影响可以忽略不计。
