Introduction. Routine surgical care has been suspended during the COVID-19 pandemic. For the treatment of patients with acute cholecystitis, conservative treatment, percutaneous drainage of the gallbladder or cholecystectomy is offered. Tactics of treatment of patients with acute cholecystitis against the background of COVID-19 have not been studied. It is important to study the data concerning the time of cholecystectomy in acute cholecystitis, comparing "early" and "delayed" cholecystectomy, which is performed after a period of conservative therapy. Aim. To present and evaluate the results of treatment of patients with acute cholecystitis against the background of COVID-19 in the conditions of a repurposed multi-specialty hospital on the basis of the O. M. Filatov Clinic Hospital No. 15 in Moscow. Material and methods. A retrospective comparative study with history control included 16 patients with acute cholecystitis against the background of COVID-19. Mechanical jaundice syndrome was diagnosed in 3 (18.75%) patients. The diagnosis of coronavirus infection using PCR was confirmed in 5 patients, serological method-in 2 patients, and in 9 patients the diagnosis was confirmed by X-ray or CT examination with negative/doubtful PCR test results. Results. Nine (56.25%) patients were operated 4 (25%) percutaneous interventions were performed, in 3 (18.75%) cases conservative therapy was performed. Most patients were operated on within the first day of admission. In the main group, a fatal outcome occurred in 1 (6.25%) case (death from a thromboembolic complication in a patient with mechanical jaundice syndrome). Discussion. The choice of «early» cholecystectomy for acute cholecystitis, provided the condition is stable and the initial changes in the lungs are appropriate in most COVID-19 patients. Conclusion. Performing cholecystectomy in patients with coronavirus infection in an infectious hospital did not lead to an increase in the duration of inpatient treatment and the prevalence of complications. The approaches mentiobed in the results section can be used as a safe method in the discussed category of patients.
