Closed circuit system in laparoscopy: SARS-CoV-2 pandemic
Keywords:SARS-CoV-2, Laparoscopy, CCS, Pneumoperitoneum, Energy device, COVID-19
Background: There is a big concern regarding transmission of Severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) during laparoscopy and using energy devices through the carbon dioxide (CO2) pneumoperitoneum. So, we decided to use a novel indigenous innovative closed-circuit system (CCS) to avoid this contamination in operation theatre.
Methods: We set out to do a prospective study in the safety of this innovative closed-circuit system in elective surgeries over 3 consecutive months of May to July 2020, during the peak of SARS-CoV-2 pandemic in a tertiary teaching hospital. We recruited 52 patients undergoing elective laparoscopic surgery in a single laparoscopy unit. The Coronavirus disease 2019 (COVID-19) status was unknown, so we presumed all patients to be potential carriers of SARS-CoV-2. However, we followed the Indian council for medical research (ICMR) and Government of Karnataka (GOK) guidelines of clinical screening before surgery. We observed the postoperative outcome regarding COVID-19 symptoms in Health care workers (HCW) involved in the operation theatre. If required, we do a real time reverse transcription polymerase chain reaction (RT-PCR) to find the true positives.
Results: Of the total 52 (basic and advanced) laparoscopic surgeries performed during this period, only 2 (3.84%) patients turned positive in the postoperative period. They developed COVID-19 symptoms and were tested positive by RT-PCR. None (100%) of the HCW developed any symptoms of COVID-19.
Conclusion: Closed circuit system is a safe and promising technique during laparoscopy.
