Surgery performed within 6 weeks for patients with Covid-19 increases the risk of death by 2.5 times

With scientific studies conducted by British scientists in 116 countries, it was determined that if surgical procedures were performed within 0-6 weeks after the diagnosis of the new type of corona virus (Cvid-19), the risk of death after surgery increased by 2.5 times.

Within the scope of the scientific study conducted by the University of Birmingham, more than 25 thousand surgeons collected the data of 140 thousand 727 patients in 1,674 hospitals in 116 countries including Australia, Brazil, China, India, United Arab Emirates (UAE), United Kingdom and United States of America (USA). carried out a comprehensive study on.

Turkey Gazi University Faculty of Medicine, Department of General Surgery, Faculty Member Prof. Dr. Sezai Leventoğlu and Medeniyet University Faculty of Medicine Department of General Surgery Faculty Member Assoc. Dr. working to increase with the leadership of the Light, researchers attended from many branches of surgery from 46 centers in Turkey.

With the results of the study published in the scientific journal “Anesthesia”, it was determined that the risk of death increased in patients who were operated 0-6 weeks after the diagnosis of new type of corona virus (SARS-CoV-2) infection.


Dr. “We recommend that the surgery be delayed as much as possible for at least 7 weeks after a positive SARS-CoV-2 test result, or until symptoms resolve if symptoms persist for at least 7 weeks or longer after diagnosis,” said Dmitri Nepogodiev in the published article on the research. used the expression.

Aneel Bhangu from the University of Birmingham said, “Since the possible advantages of a minimum 7-week delay following a SARS-CoV-2 diagnosis must be balanced against the potential risks of delay, decisions about delaying surgery should be tailored to each patient. For some emergency surgeries or advanced tumors, surgeons and patients delay may not take the risk, “he said.

Prof. Dr. Sezai Leventoğlu said in a statement, “While it is known that infection with Covid-19 increases the risk of death during surgery and international guidelines recommend delaying surgery for Covid-19 positive patients, there is little evidence on the optimal timing for surgery after the diagnosis of Covid-19,” he said. .


Giving information about the study, Leventoğlu said that the hospitals participating in the study included all patients who had a surgical procedure in October 2020. “The primary goal of the study was to determine the mortality rates within 30 days after surgery,” Leventoğlu said. he spoke.

Stating that statistical modeling is used to adjust patient, disease and operation variables and to calculate 30-day mortality rates adjusted for different time intervals from Covid-19 diagnosis to surgery, Leventoğlu said:

“In the study, lung complications (pneumonia / pneumonia, acute respiratory distress syndrome, or unexpected reventilation) and mortality rates within 30 days postoperatively were evaluated. Postoperative lung complication rates increased significantly in patients who were operated within 0-6 weeks after Covid-19 diagnosis. However, it was determined that the complaints of those who waited at least 7 weeks returned to the state before they became ill.

The time from Covid-19 diagnosis to surgery was 0-2 weeks in 1144 patients, 3-4 weeks in 461, 5-6 weeks in 327, and 7 weeks or longer in 1205 patients.

The mortality rate in the operated patients increased by 4 percent in the 0-2 week, 4 percent in the 3-4th week and 3.6 percent in the 5th-6th week, but this rate was 1 percent in 7-8 weeks after the Covid-19 diagnosis It’s 5. “
