SARS-CoV-2 vaccination modelling for safe surgery to save lives: data from an international prospective cohort study

Abstract Background Preoperative SARS-CoV-2 vaccination could support safer elective surgery. Vaccine numbers are limited so this study aimed to inform their prioritization by modelling. Methods The primary outcome was the number needed to vaccinate (NNV) to prevent one COVID-19-related death in 1 year. NNVs were based on postoperative SARS-CoV-2 rates and mortality in an international cohort study (surgical patients), and community SARS-CoV-2 incidence and case fatality data (general population). NNV estimates were stratified by age (18–49, 50–69, 70 or more years) and type of surgery. Best- and worst-case scenarios were used to describe uncertainty. Results NNVs were more favourable in su…

Model of Wound Healing for Esophagogastric Anastomoses in Rats

<b><i>Background:</i></b> Anastomotic leakage after esophageal surgery is a significant cause of morbidity and mortality. Postoperative leakage of esophagogastric anastomosis has been reported in 2–30% of surgical patient, resulting in an increased need for reoperation and a high risk of subsequent esophageal stricture formation and fistula. So far, experimental investigations on major factors influencing the healing of esophageal anastomoses, e.g. neovascularization and collagen deposition, have been hindered by the lack of a functional rodent model. <b><i>Methods:</i></b> We developed a novel technique of gastric tube formation followed by e…

Malignant and Unclear Histological Findings in Incidentalomas

<i>Background:</i> The management of incidentalomas with tumor size 3 cm and larger is still under controversial discussion. <i>Study Design:</i> Clinical charts of 65 patients who underwent adrenalectomy for an incidentaloma were reviewed. <i>Results:</i> Sixty-five patients were operated. There were 28 men and 37 women with a median age of 56.9 years. Median size of all resected lesions was 4.1 cm. Indications for surgery were tumor size equal and larger than 3 cm, recurrent pain, hormone status and patients’ fear of malignancy. In 45 patients, the adenomas did not meet the defined criteria of malignancy. There were 9 cases of adrenal hyperplasia, and t…
