To compare the cost and performance of 2 types of laparoscopic instrumentation: reusable laparoscopic hook cautery instruments and curved scissors, or limited-reuse laparoscopic hook cautery instruments and curved scissors.
A randomized trial.
The operating room of a tertiary care hospital.
All general surgeons performing laparoscopic procedures at the hospital were randomized to be supplied with either reusable or limited-reuse hook cautery and curved scissors. Instrument use was recorded, together with principal outcome measures.
Life expectancy of the instruments, the number of cases for which they were used, the number, nature and cost of repairs, their purchase cost and surgeon satisfaction.
Reusable hook cautery instruments were less expensive than their limited-reuse counterparts. Excellent surgeon satisfaction was reported with the use of this type of instrument. The limited-reuse curved scissors arm of the study was terminated early because of a breach in study protocol.
Reusable hook cautery instruments were better than their limited-reuse counterparts. Rigorous attempts to compare the cost of laparoscopic instruments may be limited by their rapid evolution in design and the availability of many types of instruments on the market.
比较两种类型的腹腔镜器械的成本和性能:可重复使用的腹腔镜钩形电灼器械和弯剪,或有限重复使用的腹腔镜钩形电灼器械和弯剪。
一项随机试验。
一家三级护理医院的手术室。
在该医院进行腹腔镜手术的所有普通外科医生被随机分配,供应可重复使用或有限重复使用的钩形电灼器械和弯剪。记录器械的使用情况以及主要结局指标。
器械的预期寿命、使用它们的病例数、维修的次数、性质和成本、购买成本以及外科医生的满意度。
可重复使用的钩形电灼器械比有限重复使用的同类器械成本更低。使用这类器械时,外科医生的满意度很高。由于违反研究方案,该研究中有限重复使用弯剪组提前终止。
可重复使用的钩形电灼器械优于有限重复使用的同类器械。对腹腔镜器械成本进行严格比较的尝试可能会受到其设计的快速演变以及市场上多种器械供应情况的限制。
