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.

Background: Obstructive jaundice is a term that describes the clinical entity of yellowness of the skin and mucous membranes due to the inability of bile to flow freely into the duodenum. This is commonly due to mechanical or physiological blockage of either the intrahepatic or extrahepatic bile ducts. Malignancies are responsible for the most cases of obstructive jaundice in our locality. Aim: The study sought to analyse all cases of obstructive jaundice that presented to a tertiary referral centre over a 36-month period, to determine the age at presentation, sex distribution, and aetiological spectrum. Study Design: Retrospective cross-sectional study. Study Setting: Korle-Bu Teaching Hospital, Accra, Ghana. Materials and Methods: This was a hospital-based study of all cases of obstructive jaundice that were seen over a 36-month period from May 2017 to April 2020, at the Hepatobiliary Unit of the Korle-Bu Teaching Hospital. The unit serves as a referral centre for all liver, pancreas, and biliary tract cases, including cases presenting with obstructive jaundice. The demographic data and diagnosis of all cases of obstructive jaundice seen over the study period were retrieved from both out-patient and in-patient records. Results: Three hundred and sixty cases of obstructive jaundice were studied; 141 (39.2%) were males and 219 (60.8%) were females, giving a male-to-female ratio of 1:1.6. The mean age of the patients was 56.8 (SD, 15.9) years. Malignant conditions accounted for 314 (87.2%) cases, whilst 46 (12.8%) were due to benign conditions. The mean age of the patients with benign conditions (40.4 [SD, 15.7] years) was significantly lower than that of those with malignant conditions (59.4 [SD, 14.9] years) ( P < 0.0001). There was no significant difference in sex ratios between patients with malignant and benign causes ( P = 0.996). Pancreatic head cancer was the commonest malignant cause of obstructive jaundice accounting for 139 (38.61%), followed by gallbladder tumour, 81 (22.5%), whilst choledocholithiasis (23 [6.39%]) was the commonest benign cause of obstructive jaundice. Conclusion: Obstructive jaundice in our setting was more prevalent in females. Malignant aetiologies were more common than benign ones: pancreatic head and gallbladder cancers were the commonest malignancies, whilst choledocholithiasis was the commonest benign cause. Malignant causes occurred in older patients than benign conditions, but there was no difference in sex ratios between the two categories.

Gallstone ileus is an uncommon cause of intestinal obstruction in Ghana. A patient with gallstone ileus that was diagnosed intra-operatively after being treated conservatively as adhesive small bowel obstruction for ten days is reported to highlight the importance of the clinical information in this condition. A 60-year-old Chinese male with recurrent intestinal obstruction who was initially being managed at a primary healthcare facility was subsequently referred to a tertiary hospital on account of computer tomography diagnosis of an intraluminal object obstructing the bowel. He had hypokalaemia that was corrected before surgery. Intra-operatively, a 4.5cm in diameter gallstone was removed from the terminal ileum. Gallstone ileus is rare in Ghana. A high index of suspicion is required to avoid a delay in diagnosis due to the low incidence of cholelithiasis in Ghana.
