Characteristics of emergency general surgery services in Switzerland: a nationwide survey.

OBJECTIVE Running an emergency general surgery (EGS) service is challenging and requires significant personnel and institutional resources. The aim of this study was to achieve a nationwide overview of the individual EGS service organizations in public hospitals in Switzerland. METHODS All Swiss public hospitals with a surgical and emergency department were included and contacted by telephone. General surgeons were interviewed between December 2021 and January 2022 using a standardized questionnaire. RESULTS Seventy-two out of 79 public hospitals in Switzerland (91.1%) agreed to the survey. They employed 1,581 surgeons in 19 (26.4%) hospitals with  600 beds. The median number of surgeons per hospital was 20.5 (IQR 13.0-29.0). Higher level of care (intermediate or intensive care unit) was significantly less available in small hospitals ( 600 beds). With increasing hospital size, there was a significant increase in the number of surgical units where EGS and orthopedic trauma surgery were covered by two separate teams (21.1% vs. 43.6% vs. 85.7% vs. 100%, p = 0.035). The median number of surgeons on-call per hospital and per 24 h was 5.0 (IQR 3.3-6.0). CONCLUSION Lack of higher level of care in small hospitals, limited emergency OR capacity and short rotations of on-call teams are major drawbacks of many current EGS systems in Switzerland. Centralization of critically ill EGS patients and reorganization of surgical on-call systems to designated acute care surgery teams should be considered

Dimensions of the Ascending Aorta in Conotruncal Heart Defects

Dilatation of the ascending aorta is an important sequel in conotruncal anomalies, such as tetralogy of Fallot (TOF) or d-transposition of the great arteries (TGA). We measured dimensions and their progression at different levels of the ascending aorta in 80 patients. In TOF patients, mean z-score for aortic annulus was 1.65 (range −3.16-6.47), for sinus 1.93 (range −2.28-5.39), for st-junction 4.15 (range 0.0-8.18), and for ascending aorta 3.51 (range −1.23-6.36). Over time, annulus z-scores increased in the univariate analysis [0.07/year, 95% confidence interval (CI) 0.01-0.14; p=0.02], and this was unique to male patients (0.08/year, 95% CI 0.00-0.15; p=0.05). z-scores of the ascending aorta decreased (−0.1/year, 95% CI −0.18 to −0.02; p=0.02), and this was confined to patients without aortic regurgitation (AR; −0.09/year, 95% CI −0.18 to −0.01; p=0.04). In TGA, mean z-score for the aortic annulus was 2.13 (range −3.71-8.39), for sinus 1.77 (range −3.04-6.69), for st-junction 1.01 (range −5.44-6.71), and for ascending aorta 0.82 (range −4.91-6.46). In bivariate analysis, annulus z-scores decreased in females (−0.14/year, 95% CI −0.25 to −0.03; p=0.01) and in patients without AR (−0.07/year, 95% CI −0.14-0.0; p=0.03). z-scores of the ascending aorta increased significantly in males (0.08/year, 95% CI 0.0 to 0.16; p=0.05) and in patients with AR (0.12/year, 95% CI 0.03-0.21; p=0.01). In conclusion, TOF and TGA z-scores of the ascending aorta differ significantly from those of the normal population. Progression of z-scores over time is influenced by diagnosis, sex, and presence of AR
