The current study demonstrated that all the tested devices are efficacious and safe in sealing and cutting arteries up to 5 mm in diameter. All the devices showed supraphysiologic mean burst pressures. Differences in failure rate, thermal damage, and process time lead to an advised application of the different systems.

Background While extensive data are available on the postponement of elective surgical procedures due to the COVID-19 pandemic for Germany, data on the impact on emergency procedures is limited. Methods In this retrospective case–control study, anonymized case-related routine data of a Germany-wide voluntary hospital association (CLINOTEL association) of 66 hospitals was analyzed. Operation volumes, in-hospital mortality, and COVID-19 prevalence rates in digestive surgery procedure groups and selected single surgical procedures in the one-year periods before and after the outbreak of the COVID-19 pandemic were analyzed. The analysis was stratified by admitting department (direct admission or transfer to the general surgical department, i.e., primary or secondary surgical patients) and type of admission (elective/emergent). Results The total number of primary and secondary surgical patients decreased by 22.7% and 11.7%, respectively. Among primary surgical patients more pronounced reductions were observed in elective (-25.6%) than emergency cases (-18.8%). Most affected procedures were thyroidectomies (-30.2%), operations on the anus (-24.2%), and closure of abdominal hernias (-23.9%; all P’s < 0.001). Declines were also observed in colorectal (-9.0%, P = 0.002), but not in rectal cancer surgery (-3.9%, n.s.). Mortality was slightly increased in primary (1.3 vs. 1.5%, P < 0.001), but not in secondary surgical cases. The one-year prevalence of COVID-19 in general surgical patients was low (0.6%), but a significant driver of mortality (OR = 9.63, P < 0.001). Conclusions Compared to the previous year period, the number of patients in general and visceral surgery decreased by 22.7% in the first pandemic year. At the procedure level, a decrease of 14.8% was observed for elective procedures and 6.0% for emergency procedures. COVID-19 infections in general surgical patients are rare (0.6% prevalence), but associated with high mortality (21.8%). Trial registration The present study does not meet the ICMJE definition of a clinical trial and was therefore not registered.
