Peri-operative SARS-CoV-2 infection increases postoperative mortality. The aim of this study was to determine the optimal duration of planned delay before surgery in patients who have had SARS-CoV-2 infection. This international, multicentre, prospective cohort study included patients undergoing elective or emergency surgery during October 2020. Surgical patients with pre-operative SARS-CoV-2 infection were compared with those without previous SARS-CoV-2 infection. The primary outcome measure was 30-day postoperative mortality. Logistic regression models were used to calculate adjusted 30-day mortality rates stratified by time from diagnosis of SARS-CoV-2 infection to surgery. Among 140,231 patients (116 countries), 3127 patients (2.2%) had a pre-operative SARS-CoV-2 diagnosis. Adjusted 30-day mortality in patients without SARS-CoV-2 infection was 1.5% (95%CI 1.4-1.5). In patients with a pre-operative SARS-CoV-2 diagnosis, mortality was increased in patients having surgery within 0-2 weeks, 3-4 weeks and 5-6 weeks of the diagnosis (odds ratio (95%CI) 4.1 (3.3-4.8), 3.9 (2.6-5.1) and 3.6 (2.0-5.2), respectively). Surgery performed ≥ 7 weeks after SARS-CoV-2 diagnosis was associated with a similar mortality risk to baseline (odds ratio (95%CI) 1.5 (0.9-2.1)). After a ≥ 7 week delay in undertaking surgery following SARS-CoV-2 infection, patients with ongoing symptoms had a higher mortality than patients whose symptoms had resolved or who had been asymptomatic (6.0% (95%CI 3.2-8.7) vs. 2.4% (95%CI 1.4-3.4) vs. 1.3% (95%CI 0.6-2.0), respectively). Where possible, surgery should be delayed for at least 7 weeks following SARS-CoV-2 infection. Patients with ongoing symptoms ≥ 7 weeks from diagnosis may benefit from further delay.
SARS-CoV-2 has been associated with an increased rate of venous thromboembolism in critically ill patients. Since surgical patients are already at higher risk of venous thromboembolism than general populations, this study aimed to determine if patients with peri-operative or prior SARS-CoV-2 were at further increased risk of venous thromboembolism. We conducted a planned sub-study and analysis from an international, multicentre, prospective cohort study of elective and emergency patients undergoing surgery during October 2020. Patients from all surgical specialties were included. The primary outcome measure was venous thromboembolism (pulmonary embolism or deep vein thrombosis) within 30 days of surgery. SARS-CoV-2 diagnosis was defined as peri-operative (7 days before to 30 days after surgery); recent (1-6 weeks before surgery); previous (≥7 weeks before surgery); or none. Information on prophylaxis regimens or pre-operative anti-coagulation for baseline comorbidities was not available. Postoperative venous thromboembolism rate was 0.5% (666/123,591) in patients without SARS-CoV-2; 2.2% (50/2317) in patients with peri-operative SARS-CoV-2; 1.6% (15/953) in patients with recent SARS-CoV-2; and 1.0% (11/1148) in patients with previous SARS-CoV-2. After adjustment for confounding factors, patients with peri-operative (adjusted odds ratio 1.5 (95%CI 1.1-2.0)) and recent SARS-CoV-2 (1.9 (95%CI 1.2-3.3)) remained at higher risk of venous thromboembolism, with a borderline finding in previous SARS-CoV-2 (1.7 (95%CI 0.9-3.0)). Overall, venous thromboembolism was independently associated with 30-day mortality ). In patients with SARS-CoV-2, mortality without venous thromboembolism was 7.4% (319/4342) and with venous thromboembolism was 40.8% (31/76). Patients undergoing surgery with peri-operative or recent SARS-CoV-2 appear to be at increased risk of postoperative venous thromboembolism compared with patients with no history of SARS-CoV-2 infection. Optimal venous thromboembolism prophylaxis and treatment are unknown in this cohort of patients, and these data should be interpreted accordingly.
Introduction We report a case of Severe acute respiratory syndrome coronavirus-2 infection with acute pancreatitis as the only presenting symptom. To the best of our knowledge, there are few case reports of the same presentation. Case presentation An otherwise healthy 44-year-old white male from Egypt presented to the hospital with severe epigastric pain and over ten attacks of nonprojectile vomiting (first, gastric content, then bilious). Acute pancreatitis was suspected and confirmed by serum amylase, serum lipase, and computed tomography scan that showed mild diffuse enlargement of the pancreas. The patient did not have any risk factor for acute pancreatitis, and extensive investigations did not reveal a clear etiology. Given a potential occupational exposure, a nasopharyngeal swab for polymerase chain reaction testing for severe acute respiratory syndrome coronavirus 2 was done, which was positive despite the absence of the typical symptoms of severe acute respiratory syndrome coronavirus 2 such as fever and respiratory symptoms. The patient was managed conservatively. For pancreatitis, he was kept nil per os for 2 days and received intravenous lactated Ringer’s (10 ml per kg per hour), nalbuphine, alpha chymotrypsin, omeprazole, and cyclizine lactate. For severe acute respiratory syndrome coronavirus 2, he received a 5-day course of intravenous azithromycin (500 mg per day). He improved quickly and was discharged by the fifth day. We know that abdominal pain is not a rare symptom of severe acute respiratory syndrome coronavirus 2, and we also know that elevated levels of serum amylase and lipase were reported in severe acute respiratory syndrome coronavirus-2 patients, especially those with severe symptoms. However, the association between severe acute respiratory syndrome coronavirus-2 infection and idiopathic acute pancreatitis is rare and has been reported only a few times. Conclusion We believe further studies should be conducted to determine the extent of pancreatic involvement in severe acute respiratory syndrome coronavirus-2 patients and the possible causality between severe acute respiratory syndrome coronavirus 2 and acute pancreatitis. We reviewed the literature regarding the association between severe acute respiratory syndrome coronavirus 2 and acute pancreatitis patients. Published data suggest that severe acute respiratory syndrome coronavirus 2 possibly could be a risk factor for acute pancreatitis.
