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

The impact of smoking on HPV infection and the development of anogenital warts

Purpose: The worldwide prevalence of human papillomavirus (HPV) infection is estimated at 9-13%. Persistent infection can lead to the development of malignant and nonmalignant diseases. Low-risk HPV types are mostly associated with benign lesions such as anogenital warts. In the present systematic review, we examined the impact of smoking on HPV infection and the development of anogenital warts, respectively. Methods: A systematic literature search was performed using MEDLINE database for peer-reviewed articles published from January 01, 1985 to November 30, 2013. Pooled rates of HPV prevalence were compared using the χ 2 test. Results: In both genders, smoking is associated with higher incidence and prevalence rates for HPV infection, whereas the latter responds to a dose-effect relationship. The overall HPV prevalence for smoking patients was 48.2 versus 37. 5% for nonsmoking patients (p < 0.001) (odds ratio (OR) = 1.5, 95% confidence interval (CI) 1.4-1.7). Smoking does also increase persistence rates for high-risk HPV infection, while this correlation is debatable for low-risk HPV. The incidence and recurrence rates of anogenital warts are significantly increased in smokers. Conclusions: Most current data demonstrate an association between smoking, increased anogenital HPV infection, and development of anogenital warts. These data add to the long list of reasons for making smoking cessation a keystone of patient health

Long-Term Follow-Up After Non-operative Management of Blunt Splenic and Liver Injuries: A Questionnaire-Based Survey.

BACKGROUND Non-operative management (NOM) of blunt splenic or liver injuries (solid organ injury, SOI) has become the standard of care in hemodynamically stable patients. However, the incidence of long-term symptoms in these patients is currently not known. The aim of this study was to assess long-term symptoms in patients undergoing successful NOM (sNOM) for SOI. METHODS Long-term posttraumatic outcomes including chronic abdominal pain, irregular bowel movements, and recurrent infections were assessed using a specifically designed questionnaire and analyzed by univariable analysis. RESULTS Eighty out of 138 (58%) patients with SOI undergoing sNOM) responded to the questionnaire. Median (IQR) follow-up time was 48.8 (28) months. Twenty-seven (34%) patients complained of at least one of the following symptoms: 17 (53%) chronic abdominal pain, 13 (41%) irregular bowel movements, and 8 (25%) recurrent infections. One female patient reported secondary infertility. No significant association between the above-mentioned symptoms and the Injury Severity Score, amount of hemoperitoneum, or high-grade SOI was found. Patients with chronic pain were significantly younger than asymptomatic patients (32.1 ± 14.5 vs. 48.3 ± 19.4 years, p = 0.002). Irregular bowel movements were significantly more frequent in patients with severe pelvic fractures (15.4 vs. 0.0%, p = 0.025). A trend toward a higher frequency of recurrent infections was found in patients with splenic injuries (15.9 vs. 2.8%, p = 0.067). CONCLUSION A third of patients with blunt SOI undergoing sNOM reported long-term abdominal symptoms. Younger age was associated with chronic abdominal symptoms. More studies are warranted to investigate long-term outcomes immunologic sequelae in patients after sNOM for SOI

Transdiaphragmatic Resuscitative Open Cardiac Massage: Description of the Technique and a First Case-Series of an Alternative Approach to the Heart

Background: The purpose of this paper is to describe the transdiaphragmatic approach to the heart for open CPR in patients that arrest at laparotomy and to present a first case series of patients that have undergone this procedure. Methods: All patients who had undergone intraperitoneal transdiaphragmatic open CPR between January 1, 2002 and December 31, 2012 were retrieved from the operation registry at Bern University Hospital, Switzerland. Transdiaphragmatic access to the heart is initiated with a 10-cm-long anterocaudal incision in the central tendon of the diaphragm—approximately at 2 o'clock. Internal cardiac compression through the diaphragmatic incision can be performed from both sides of the patient. From the right side of the patient, cardiac massage is performed with the right hand and vice versa. Results: A total of six patients were identified that suffered cardiac arrest during laparotomy with open CPR performed through the transdiaphragmatic approach. Four patients suffered cardiac arrest during orthotopic liver transplantation and two trauma patients suffered cardiac arrest during damage control laparotomy. In three patients, cardiac activity was never reestablished. However, three patients regained a perfusion heart rhythm and two of these survived to the ICU. One patient ultimately survived to discharge. Conclusions: In patients suffering cardiac arrest during laparotomy, the transdiaphragmatic approach allows for a rapid, technically easy, and almost atraumatic access to the heart, with excellent CPR performance. After this potentially life-saving procedure, pulmonary or surgical site complications are expected to occur much less compared with the conventionally performed emergency department left-sided thoracotomy

Work Characteristics of Acute Care Surgeons at a Swiss Tertiary Care Hospital: A Prospective One-Month Snapshot Study.

BACKGROUND Multiple acute care surgery (ACS) working models have been implemented. To optimize resources and on-call rosters, knowledge about work characteristics is required. Therefore, this study aimed to investigate the daily work characteristics of ACS surgeons at a Swiss tertiary care hospital. METHODS Single-center prospective snapshot study. In February 2020, ACS fellows prospectively recorded their work characteristics, case volume and surgical case mix for 20 day shifts and 16 night shifts. Work characteristics were categorized in 11 different activities and documented in intervals of 30 min. Descriptive statistics were applied. RESULTS A total of 432.5 working hours (h) were documented and characterized. The three main activities 'surgery,' 'patient consultations' and 'administrative work' ranged from 30.8 to 35.9% of the documented working time. A total of 46 surgical interventions were performed. In total, during day shifts, there were 16 elective and 15 emergency interventions, during night shifts 15 emergency interventions. For surgery, two peaks between 10:00 a.m.-02:00 p.m. and 08:00 p.m.-11:00 p.m. were observed. A total of 225 patient were consulted, with a first peak between 08:00 a.m. and 11:00 a.m. and a second, wider peak between 02:00 p.m. and 02:00 a.m. CONCLUSION The three main activities 'surgery,' 'patient consultations' and 'administrative work' were comparable with approximately one third of the working time each. There was a bimodal temporal distribution for both surgery and patient consultations. These results may help to improve hospital resources and on-call rosters of ACS services

Pre-injury stimulant use in isolated severe traumatic brain injury: effect on outcomes.

PURPOSE The aim of this study was to assess the impact of pre-injury stimulant use (amphetamine, cocaine, methamphetamine and/or ecstasy) on outcomes after isolated severe traumatic brain injury (TBI). METHODS Retrospective 2017 TQIP study, including adult trauma patients (≥16 years old) who underwent drug and alcohol screening on admission and sustained an isolated severe TBI (head AIS ≥3). Patients with significant extracranial trauma (AIS ≥3) were excluded. Epidemiological and clinical characteristics, procedures and outcome variables were collected. Patients with isolated stimulant use were matched 1:1 for age, gender, mechanism of injury, head AIS and overall comorbidities, with patients with negative toxicology and alcohol screen. Outcomes in the two groups were compared with univariable and multivariable regression analysis. RESULTS 681 patients with isolated TBI and stimulant use were matched with 681 patients with negative toxicology and alcohol screen. The incidence of hypotension and CGS <9 was similar in the two groups. In multivariable regression analysis, stimulant use was not independently associated with mortality (OR 0.95, 95% CI 0.61-1.49). However, stimulant use was associated with longer hospital length of stay (HLOS) (RC 1.13, 95%CI 1.03-1.24). CONCLUSION Pre-injury stimulant use is common in patients admitted for severe TBI, but was not independently associated with mortality when compared to patients with negative toxicology. However, stimulant use was associated with a significant longer HLOS

Effect of C-Clamp Application on Hemodynamic Instability in Polytrauma Victims with Pelvic Fracture.

Background and Objectives: C-clamp application may reduce mortality in patients with unstable pelvic fractures and hemodynamic instability. Decreasing C-clamp use over the past decades may have resulted from concerns about its effectiveness and safety. The purpose of this study was to document effective hemodynamic stabilization after C-clamp application by means of vital parameters (primary outcome parameter), and the subsequent effect on metabolic indices and volume management (secondary outcome parameters). Materials and Methods: C-clamp application was performed between 2014 and 2021 for n = 13 patients (50 ± 18 years) with unstable pelvic fractures and hemodynamic instability. Vital parameters, metabolic indices, volume management, and the correlation of factors and potential changes were analyzed. Results: After C-clamp application, increases were measured in systolic blood pressure (+15 mmHg; p = 0.0284) and mean arterial pressure (+12 mmHg; p = 0.0157), and a reduction of volume requirements (p = 0.0266) and bolus vasoactive medication needs (p = 0.0081) were observed. The earlier C-clamp application was performed, the greater the effect (p &lt; 0.05; r &gt; 0.6). Heart rate, shock index, and end-tidal CO2 were not significantly altered. The extent of base deficit, hemoglobin, and lactate did not correlate with changes in vital parameters. Conclusions: In the majority of hemodynamically unstable trauma patients not responding to initial fluid resuscitation and severe pelvic fracture, early C-clamp application had an additive effect on hemodynamic stabilization and reduction in volume substitution. Based on these findings, there is still a rationale for considering early C-clamp stabilization in this group of severely injured patients

Introduction of a New Policy of no Nighttime Appendectomies: Impact on Appendiceal Perforation Rates and Postoperative Morbidity

Background: Working hour limitations and tight health care budgets have posed significant challenges to emergency surgical services. Since 1 January 2010, surgical interventions at Berne University Hospital between 23:00 and 08:00h have been restricted to patients with an expected serious adverse outcome if not operated on within 6h. This study was designed to assess the safety of this new policy that restricts nighttime appendectomies (AEs). Methods: The patients that underwent AE from 1 January 2010 to 31 December 2011 ("2010-2011 group”) were compared retrospectively with patients that underwent AE before introduction of the new policy (1 January 2006-31 December 2009; "2006-2009 group”). Results: Overall, 390 patients were analyzed. There were 255 patients in the 2006-2009 group and 135 patients in the 2010-2011 group. Patients' demographics did not differ statistically between the two study groups; however, 45.9% of the 2006-2009 group and 18.5% of the 2010-2011 group were operated between 23:00 and 08:00h (p12h was significantly greater in the 2010-2011 group than in the 2006-2009 group [55.6 vs. 43.5%, p=0.024, odds ratio (95% confidence interval 1.62 (1.1-2.47)]. Conclusions: Restricting AEs from 23:00 to 08:00h does not increase the perforation rates and occurrence of clinical outcomes. Therefore, these results suggest that appendicitis may be managed safely in a semielective manner
