During the coronavirus disease 2019 (COVID-19) pandemic, the use of laparoscopy has been discouraged by the Intercollegiate General Surgery because of its potential for aerosol generation and infection. In contrast, the Society of American Gastrointestinal and Endoscopic Surgeons and the European Association of Endoscopic Surgery recommend continuing to use laparoscopy but with devices to filter released CO aerosol particles. However, commercially available systems are costly and may not be readily available. Herein, we describe a custom-made system to safely remove surgical smoke and CO , as well as a case of laparoscopic cholecystectomy in which we used it.
The patient had had multiple episodes of biliary pancreatitis and required urgent cholecystectomy during the COVID-19 pandemic. Although India was in complete lockdown, it was decided to operate with precaution. A system was designed using underwater seal chest tube drainage and an electrostatic membrane filter with a viral retention function greater than 99.99%. The system was connected to an extra port for continuous controlled egression of CO pneumoperitoneum. A regular four-port cholecystectomy was performed at an intra-abdominal pressure of 12 mm Hg. The gas flow rate was 10 L/min. CO for pneumoperitoneum, surgical aerosol, and effluents passed through the system before collecting in the suction apparatus. The exchange of operating instruments through the ports was kept to a minimum. It was done after the abdomen was temporarily desufflated using this system.
The system we designed appears safe and is cost-effective. In resource-limited settings, it will be handy in patients requiring laparoscopic surgery both during and after the COVID-19 pandemic.
在2019年冠状病毒病(COVID-19)大流行期间,由于腹腔镜检查可能产生气溶胶并导致感染,大学间普通外科协会不鼓励使用该技术。相比之下,美国胃肠和内镜外科医师协会以及欧洲内镜外科学会建议继续使用腹腔镜检查,但需配备过滤释放的二氧化碳气溶胶颗粒的装置。然而,市售系统成本高昂且可能不易获得。在此,我们描述一种用于安全去除手术烟雾和二氧化碳的定制系统,以及一例使用该系统的腹腔镜胆囊切除术病例。
该患者曾多次发作胆源性胰腺炎,在COVID-19大流行期间需要紧急进行胆囊切除术。尽管印度处于全面封锁状态,但仍决定采取预防措施进行手术。设计了一种系统,该系统采用水下密封胸腔引流管和具有大于99.99%病毒截留功能的静电膜过滤器。该系统连接到一个额外端口,用于持续控制二氧化碳气腹的排出。在腹腔内压力为12 mmHg的情况下进行常规四孔胆囊切除术。气体流速为10 L/min。用于气腹、手术气溶胶和流出物的二氧化碳在收集到吸引装置之前先通过该系统。通过端口交换手术器械的操作保持在最低限度。这是在使用该系统暂时使腹部放气后进行的。
我们设计的系统似乎是安全且具有成本效益的。在资源有限的环境中,它对于COVID-19大流行期间及之后需要进行腹腔镜手术的患者将很方便。
