Clear visualization of the surgical field is critical in laparoscopic surgery. The authors evaluated a device that does not necessitate an external cleaning process for the laparoscope. It was hypothesized that it will minimize the interruption in operative workflow.
A total of 40 advanced laparoscopy patients were randomized to either the control or device group. Demographic data, procedural data, length of stay, frequency and duration of lens cleaning, and lens clarity scores (LCS) were recorded. Independent samples t test and Fisher's exact test were performed.
No significant difference was found between the device and control groups in demographic data, procedure time (P = .922) or LCS (P = .124). Laparoscope cleaning in the device group was significantly shorter than in the control group (P < .001). No complications were observed.
An intra-abdominal laparoscopic cleaning device can effectively clean the laparoscopic lens and lead to less workflow interruption. Although not documented in this study, it may also lead to shorter operative times.
在腹腔镜手术中，术野的清晰可视化至关重要。作者评估了一种无需对腹腔镜进行外部清洁过程的设备。据推测，它将最大限度地减少手术流程中的中断。
总共40例高级腹腔镜手术患者被随机分为对照组或设备组。记录人口统计学数据、手术数据、住院时间、镜头清洁的频率和持续时间以及镜头清晰度评分（LCS）。进行独立样本t检验和Fisher精确检验。
在人口统计学数据、手术时间（P = 0.922）或LCS（P = 0.124）方面，设备组和对照组之间未发现显著差异。设备组的腹腔镜清洁时间明显短于对照组（P < 0.001）。未观察到并发症。
一种腹腔内腹腔镜清洁设备可以有效地清洁腹腔镜镜头，并减少对手术流程的干扰。尽管本研究未记录，但它也可能导致手术时间缩短。
