Laparoscopic Gastrointestinal Surgery During COVID-19 Pandemic: Single-Center Experience.

Background: COVID-19 era has put laparoscopic surgery a risk procedure because of theoretical risk of viral transmission of COVID-19. However, safe evacuation of stagnant air during laparoscopic surgery is also necessary to safeguard health care warriors. Methods: We are reporting experience of 24 laparoscopic surgeries using a closed smoke evacuation/filtration system using a ultra low-particulate air (ULPA) filtration capability (ConMed AirSeal® System) at a single center between March 22, 2020, and May 30, 2020. All surgeries were either urgent or emergency in nature. Results: Totally, 17 males and 7 females who required urgent surgery. Most common indication for laparoscopic intervention was acute cholecystitis and complications related to acute cholecystitis. Owing to the closed smoke evacuation system, low intra-abdominal pressure was maintained during all surgeries. Of all procedures, only 0.8 time per procedure, the laparoscope taken out for cleaning. Mean time for completion of surgery was 58 minutes. Compliance of surgical staff was high due to the deemed safe smoke evacuation system. Mean of postoperative pain score was low. Mean hospital stay was 4.9 days. Conclusions: We propose to use a closed smoke evacuation/filtration system with ULPA filtration capability or similar devices in each minimally invasive surgery to reduce risks of transmission as minute as possible until we have enough knowledge about the pattern of disease transmission.

COVID-19: impact on colorectal surgery.

AIM: The rapid spread of the COVID-19 pandemic has created unprecedented challenges for the medical and surgical healthcare systems. With the ongoing need for urgent and emergency colorectal surgery, including surgery for colorectal cancer, several questions pertaining to operating room (OR) utilization and techniques needed to be rapidly addressed. METHOD: This manuscript discusses knowledge related to the critical considerations of patient and caregiver safety relating to personal protective equipment (PPE) and the operating room environment. RESULTS: During the COVID-19 pandemic, additional personal protective equipment (PPE) may be required contingent upon local availability of COVID-19 testing and the incidence of known COVID-19 infection in the respective community. In addition to standard COVID-19 PPE precautions, a negative-pressure environment, including an OR, has been recommended, especially for the performance of aerosol-generating procedures (AGPs). Hospital spaces ranging from patient wards to ORs to endoscopy rooms have been successfully converted from standard positive-pressure to negative-pressure spaces. Another important consideration is the method of surgical access; specifically, minimally invasive surgery with pneumoperitoneum is an AGP and thus must be carefully considered. Current debate centres around whether it should be avoided in patients known to be infected with SARS-CoV-2 or whether it can be performed under precautions with safety measures in place to minimize exposure to aerosolized virus particles. Several important lessons learned from pressurized intraperitoneal aerosolized chemotherapy procedures are demonstrated to help improve our understanding and management. CONCLUSION: This paper evaluates the issues surrounding these challenges including the OR environment and AGPs which are germane to surgical practices around the world. Although there is no single universally agreed upon set of answers, we have presented what we think is a balanced cogent description of logical safe approaches to colorectal surgery during the COVID-19 pandemic.
