ABSTRACT

AIMS: Patients undergoing emergency general surgery are at high risk of complications and death. Our objectives were to estimate the incidence of emergency general surgery in a Swiss University Hospital, to describe the characteristics and outcomes of patients undergoing such procedures, and to study the impact of age on clinical outcomes. METHODS: This was a retrospective cohort study of adult patients who visited the emergency department (ED) of Geneva University Hospitals between January 2015 and December 2019. Routinely collected data were extracted from electronic medical records. The primary outcome was the incidence of emergency general surgery among patients visiting the emergency department, defined as general surgery within three days of emergency department admission. We also assessed demographic characteristics, mortality, intensive care unit admission and patient disposition. Multivariable log-binomial regression was used to study the associations of age with intensive care unit (ICU) admission, one-year mortality and dependence at discharge. Age was modelled as a continuous variable using restricted cubic splines and we compared older patients (75th percentile) with younger patients (25th percentile). RESULTS: Between January 2015 and December 2019, a total of 310,914 emergency department visits met our inclusion criteria. Among them, 3592 patients underwent emergency general surgery within 3 days of emergency department admission, yielding an annual incidence of 116 events per 10,000 emergency department visits (95% CI: 112-119), with a higher incidence in females and young patients. Overall, 5.3% of patients were admitted to ICU, 7.8% were dependent on rehabilitation or assisted living at discharge and 4.8% were dead after one year. Older patients had a higher risk of ICU admission (adjusted risk ratio (aRR) 2.9 [1.5-5.4]), dependence at discharge (aRR 15.3 [5.5-42.4]) and one-year mortality (aRR 5.4 [2.2-13.4]). CONCLUSION: Emergency department visits resulting in emergency general surgery are frequent, but their incidence decreases with patient age. Mortality, ICU admission and dependence at discharge following emergency general surgery are more frequent in older patients. Taking into account the increased risk for older patients, a shared process is appropriate for making more informed decisions about their options for care.

ABSTRACT

BACKGROUND: Pelvic ring injuries are potentially lethal lesions associated with polytrauma patients and need an efficient trauma team for their management. The purpose of this study was to evaluate the incidence of high-energy blunt pelvic ring injuries and the absolute number of polytrauma patients in a single level I trauma center during the 2020 pseudo-lockdown period related to the Coronavirus pandemic, and to compare it with corresponding periods in 2014-2019 in order to better understand the need of organized and dedicated personnel and infrastructures. METHODS: This retrospective cohort study was based on data prospectively recorded into the institutional Severely Injured Patients' Registry. Data were obtained for each year period (January 1st to December 31st) and corresponding pseudo-lockdown period (March 16th to June 19th). High-energy blunt pelvic ring injuries inclusion criteria were: (1) Registry entry between January 1st, 2014 and December 31st, 2020; (2) age ≥ 16 years old; and (3) pelvic ring injury presence. Corresponding exclusion criteria were: (1) death before admission; (2) transfer from another institution > 24 h after trauma; (3) penetrating, blast, burn and electrical injuries, drownings; (4) patients living outside the defined institution's catchment area; and (5) any document attesting the patient's will to not participate in any study. Polytrauma patients inclusion criteria were: (1) Registry entry between January 1st, 2014 and December 31st, 2020; (2) age ≥ 16 years old; and (3) Injury Severity Score ≥ 16. Corresponding exclusion criteria were: (1) death before admission; (2) transfer from another institution > 24 h after trauma; and (3) any document attesting the patient's will to not participate in any study. Categorical variables were reported using proportions and continuous variables using medians and interquartile ranges. Because data were exhaustive for the authors' level I trauma center, no inferential statistics were computed. RESULTS: The incidence of high-energy blunt pelvic ring injuries and the absolute number of polytrauma patients remained within range of previous years despite pseudo-lockdown measures. CONCLUSIONS: These observations bring better knowledge about pseudo-lockdown's impact on trauma and may help for future health strategy planning by pointing out the importance of maintaining the activity of level I trauma centers in terms of personnel and infrastructures.

ABSTRACT

BACKGROUND: High-energy pelvic ring injuries (PRI) represent a heavy burden for institutions treating severely injured patients. Epidemiological data knowledge may help to provide them appropriate management. Only two epidemiologic studies about high-energy PRI were published during last decade. This study aimed to determine the gender-specific and global incidences of high-energy blunt AO/OTA type B or C PRI and their frequency among high-energy blunt trauma. It further reports the spectrum of these injuries and compares their characteristics and outcomes to high-energy blunt trauma without type B or C PRI. HYPOTHESIS: Type B or C PRI incidence isn't gender specific and approximates 5/100,000/year. PATIENTS AND METHODS: A prospective database of a level-I trauma center serving approximately 500,000 inhabitants was retrospectively queried for all high-energy trauma patients injured between 01.01.2014 and 12.31.2016. Inclusion criteria were: alive emergency department delivery; entire acute treatment at the authors' institution; age >16. Exclusion criteria were: penetrating, blast, burn and electrical injuries; drownings; low-energy trauma; patients living outside the institution's catchment area. Three authors performed PRI classifications. Clinical data were extracted from the database. RESULTS: We analyzed 434 patients. High-energy blunt type B or C PRI incidence was 3.8/100,000/year without gender disparity (p=0.6697). High-energy blunt trauma incidence was lower in women than in men (20.5 vs. 51.6/100,000/year, p<0.001). Type B or C PRI frequency during high-energy blunt trauma was higher in women than in men (17.6% vs. 7.9%, p=0.003). Type B or C PRI patients were more severely injured and needed more treatment resources than other high-energy blunt trauma patients but didn't present higher complication or death rates. DISCUSSION: The incidence of high-energy blunt type B or C PRI was comparable to previously published data. Women were less likely to sustain a high-energy blunt trauma, but when they sustained one, they were more likely to have a type B or C PRI. Despite higher injury severity score and resource requirements, complication and death rates weren't different between type B or C PRI patients and other high-energy blunt trauma patients. LEVEL OF EVIDENCE: Level III, retrospective cohort study.

ABSTRACT

Since mid-2013, data on high-energy trauma patients admitted to the Emergency Department of the University Hospitals of Geneva, Switzerland, are prospectively recorded in a dedicated registry. This includes data on patients with high-energy blunt pelvic ring injuries (PRI), defined as closed fracture of the pelvic ring following falls from a height >1 m, road traffic accidents, sport, crush, farm and industrial injuries. The registry was screened for patients aged ≥16 years with high-energy blunt PRI admitted to the aforementioned academic level I trauma center between 2014.01.01 et 2019.12.31, to assess the outcome of the institutional PRI management protocol. Data on 195 patients were collected and analyzed for this purpose [1]. The dataset "patients' demographic and injury characteristics" provides the raw demographics and Abbreviated Injury Scale (AIS) of these 195 patients. These data can contribute to the knowledge of patients' demographics and injury characteristics of high-energy blunt PRI patients.

ABSTRACT

INTRODUCTION: High-energy blunt pelvic ring injuries with hemodynamic instability are complicated by a high mortality rate (up to 32%). There is no consensus on the best management strategy for these injuries. The aim of this study was to evaluate the high-energy blunt pelvic ring injury management protocol implemented in the authors' institution. PATIENTS AND METHODS: This retrospective cohort study was performed in an academic level I trauma center. The institutional protocol incorporates urgent pelvic mechanical stabilization of hemodynamically unstable patients not responding to a pelvic belt, fluids, and transfusions. If hemodynamic instability persists, angiography ± embolization is performed. Adult patients sustaining a high-energy blunt pelvic ring injury between 2014.01.01 and 2019.12.31 were included in the study. The primary outcome was mortality at 1, 2, 30 and 60 days. The secondary outcomes were the number of packed red blood cell units transfused during the first 24 h, intensive care unit stay, and total hospitalization length of stay. RESULTS: 192 high-energy blunt pelvic ring injury patients were analyzed. Of these, 71 (37%) were hemodynamically unstable, and 121 (63%) were stable. The overall in-hospital mortality of the hemodynamically unstable and stable groups was 20/71 (28.2%) and 4/121 (3.3%) respectively (p<0.001). Cumulative mortality rates for hemodynamically unstable patients were 15.5% at day 1, 16.9% at day 2, 26.8% at day 30 and 28.2% at day 60, and for hemodynamically stable patients, rates were 0% at day 1 and 2, 2.5% at day 30 and 3.3% at day 60. Unstable patients required a higher number of packed red blood cell units than stable patients during the first 24 h (5.1 vs. 0.1; p<0.001). Intensive care unit length of stay and total hospitalization duration was 11.25 and 37.4 days for unstable patients and 1.9 and 20.9 days for stable patients (p<0.001). CONCLUSIONS: For both hemodynamically unstable and stable patients, the institutional protocol showed favorable mortality rates when compared to available literature. Comparative studies are needed to determine the management strategies with the best clinical outcome and survival.

ABSTRACT

BACKGROUND: The aim of this study was to determine the rate and topography of intra-pelvic arterial lesions associated with high-energy blunt pelvic ring injuries (PRI). METHODS: This retrospective cohort study was conducted in a level I trauma center serving 500,000 inhabitants. A total of 127 consecutive patients with high-energy blunt PRI were included between January 1st, 2014 and December 31st, 2017. Every patient had a total body or thoraco-abdominal computed tomography scan including contrast enhanced arterial sequences. A board-certified radiologist reviewed all the vascular images and precisely described every intra-pelvic arterial lesion in terms of localization. Complete pelvic series (standard radiographs and fine cut computed tomography images) were reviewed by three board-certified orthopedic surgeons experienced in PRI management, and Young and Burgess and AO/OTA classifications were determined. Demographic, clinical, therapeutic and outcome data were extracted from the institutional severely injured patients' registry. RESULTS: Patients' mean age was 45.3 years and 58.3% were males. Fifteen (11.8%) had a total of 21 intra-pelvic arterial lesions: seven lesions of the obturator artery, four of the superior gluteal artery, three of the inferior gluteal artery, two of the vesical artery, and one of each of the following arteries: internal iliac, internal pudendal, fifth lumbar, lateral sacral, ilio-lumbar. These lesions occurred in 8.6% of lateral compression injuries, 33.3% of anteroposterior compression injuries and 23.5% of vertical shear and combined mechanism injuries (Young and Burgess classification, p = 0.003); and in 0% of type A injuries, 9.9% of type B injuries and 35% of type C injuries (AO/OTA classification, p = 0.001). Patients with an intra-pelvic arterial lesion were more likely to present with pre-hospital hemodynamic instability (p = 0.046) and to need packed red blood cells transfusion within the first 24 h (p = 0.023; they needed a mean of 7.53 units vs. 1.88, p = 0.0016); however, they did not have a worst outcome in terms of complications or mortality. CONCLUSIONS: This systematic study found an 11.8% rate of intra-pelvic arterial lesion related to high-energy blunt PRI. The obturator, superior gluteal and inferior gluteal arteries were most often injured. These findings are important for the aggressive management of high-energy blunt PRI.

ABSTRACT

BACKGROUND: Acute abdominal pain accounts for about 10% of emergency department visits and has progressively become the primary indication for CT scanning in most centers. The goal of our study is to identify biological or clinical variables able to predict or rule out significant pathology (conditions requiring urgent medical or surgical treatment) on abdominal CT in patients presenting to an emergency department with acute abdominal pain. METHODS: This was a retrospective cohort study performed in the emergency department of an academic center with an annual census of 60'000 patients. One hundred and-nine consecutive patients presenting with an acute non-traumatic abdominal pain, not suspected of appendicitis or renal colic, during the first semester of 2013, who underwent an abdominal CT were included. Two medical students, completing their last year of medical school, extracted the data from patients' electronic health record. Ambiguities in the formulations of clinical symptoms and signs in the patients' records were solved by consulting a board certified emergency physician. Nine clinical and biological variables were extracted: shock index, peritonism, abnormal bowel sounds, fever (> 38 °C), intensity and duration of the pain, leukocytosis (white blood cell count >11G/L), relative lymphopenia (< 15% of total leukocytes), and C-reactive Protein (CRP). These variables were compared to the CT results (reference standard) to determine their ability to predict a significant pathology. RESULTS: Significant pathology was detected on CT in 71 (65%) patients. Only leukocytosis (odds ratio 3.3, p = 0.008) and relative lymphopenia (odds ratio 3.8, p = 0.002) were associated with significant pathology on CT. The joint presence of these two anomalies was strongly associated with significant pathology on CT (odds ratio 8.2, p = 0.033). Leukocytosis with relative lymphopenia had a specificity of 89% (33/37) and sensitivity of 48% (33/69) for the detection of significant pathology on CT. CONCLUSION: The high specificity of the association between leukocytosis and relative lymphopenia amongst the study population suggests that these parameters would be sufficient to justify an emergency CT. However, none of the parameters could be used to rule out a significant pathology.

ABSTRACT

BACKGROUND: Pelvic binders are routinely used in the prehospital setting for stabilization of pelvic injuries in patients with trauma. Emergency department trauma management relies on primary and secondary survey assessment and imaging, most often computed tomography, in hemodynamically stable patients. Maintaining the pelvic binder in situ allows stabilization of pelvic injuries during imaging but may hinder the visualization of some pelvic lesions. We report a very rare case of severe pelvic disruption with an absolutely normal computed tomography scan due to the effective placement of a pelvic binder. CASE PRESENTATION: We report the case of a 49-year-old Caucasian man referred to our Emergency Department after a high velocity motorcycle accident. Primary assessment revealed a left wrist deformation and pelvic pain, and a pelvic binder was applied by paramedics. A total body computed tomography scan was performed after arrival in our Emergency Department and did not reveal any pelvic injury. The pelvic binder was removed and because of persisting symphyseal pain, pelvic plain radiography was performed revealing a pelvic disruption with an opening of the pubic symphysis and of the left sacroiliac joint ("open book" type pelvic injury) requiring surgical stabilization. CONCLUSIONS: Pelvic binders may mask pelvic disruption in patients with trauma. Pelvic plain radiography should be repeated after pelvic binder removal in patients with high velocity trauma and pelvic symptoms or neurological alterations limiting the reliability of clinical examination.

ABSTRACT

Mild traumatic brain injury (mTBI) patients may have trauma-induced brain lesions detectable using CT scans. However, most patients will be CT-negative. There is thus a need for an additional tool to detect patients at risk. Single blood biomarkers, such as S100B and GFAP, have been widely studied in mTBI patients, but to date, none seems to perform well enough. In many different diseases, combining several biomarkers into panels has become increasingly interesting for diagnoses and to enhance classification performance. The present study evaluated 13 proteins individually-H-FABP, MMP-1, MMP-3, MMP-9, VCAM, ICAM, SAA, CRP, GSTP, NKDA, PRDX1, DJ-1 and IL-10-for their capacity to differentiate between patients with and without a brain lesion according to CT results. The best performing proteins were then compared and combined with the S100B and GFAP proteins into a CT-scan triage panel. Patients diagnosed with mTBI, with a Glasgow Coma Scale score of 15 and one additional clinical symptom were enrolled at three different European sites. A blood sample was collected at hospital admission, and a CT scan was performed. Patients were divided into two two-centre cohorts and further dichotomised into CT-positive and CT-negative groups for statistical analysis. Single markers and panels were evaluated using Cohort 1. Four proteins-H-FABP, IL-10, S100B and GFAP-showed significantly higher levels in CT-positive patients. The best-performing biomarker was H-FABP, with a specificity of 32% (95% CI 23-40) and sensitivity reaching 100%. The best-performing two-marker panel for Cohort 1, subsequently validated in Cohort 2, was a combination of H-FABP and GFAP, enhancing specificity to 46% (95% CI 36-55). When adding IL-10 to this panel, specificity reached 52% (95% CI 43-61) with 100% sensitivity. These results showed that proteins combined into panels could be used to efficiently classify CT-positive and CT-negative mTBI patients.

ABSTRACT

Traumatic brain injury is a common event where 70%-90% will be classified as mild TBI (mTBI). Among these, only 10% will have a brain lesion visible via CT scan. A triage biomarker would help clinicians to identify patients with mTBI who are at risk of developing a brain lesion and require a CT scan. The brain cells damaged by the shearing, tearing and stretching of a TBI event set off inflammation cascades. These cause altered concentrations of a high number of both pro-inflammatory and anti-inflammatory proteins. This study aimed to discover a novel diagnostic biomarker of mTBI by investigating a broad panel of inflammation biomarkers and their capacity to correctly identify CT-positive and CT-negative patients. Patients enrolled in this study had been diagnosed with mTBI, had a GCS score of 15 and suffered from at least one clinical symptom. There were nine patients in the discovery group, 45 for verification, and 133 mTBI patients from two different European sites in the validation cohort. All patients gave blood samples, underwent a CT scan and were dichotomised into CT-positive and CT-negative groups for statistical analyses. The ability of each protein to classify patients was evaluated with sensitivity set at 100%. Three of the 92 inflammation proteins screened-MCP-1, MIP-1alpha and IL-10 -were further investigated in the verification group, and at 100% sensitivity their specificities reached 7%, 0% and 31%, respectively. IL-10 was validated on a larger cohort in comparison to the most studied mTBI diagnostic triage protein to date, S100B. Levels of both proteins were significantly higher in CT-positive than in CT-negative patients (p < 0.001). S100B's specificity at 100% sensitivity was 18% (95% CI 10.8-25.2), whereas IL-10 reached a specificity of 27% (95% CI 18.9-35.1). These results showed that IL-10 might be an interesting and clinically useful diagnostic tool, capable of differentiating between CT-positive and CT-negative mTBI patients.

ABSTRACT

The majority of patients with mild traumatic brain injury (mTBI) will have normal Glasgow coma scale (GCS) of 15. Furthermore, only 5%-8% of them will be CT-positive for an mTBI. Having a useful biomarker would help clinicians evaluate a patient's risk of developing intracranial lesions. The S100B protein is currently the most studied and promising biomarker for this purpose. Heart fatty-acid binding protein (H-FABP) has been highlighted in brain injury models and investigated as a biomarker for stroke and severe TBI, for example. Here, we evaluate the performances of S100B and H-FABP for differentiating between CT-positive and CT-negative patients. A total of 261 patients with a GCS score of 15 and at least one clinical symptom of mTBI were recruited at three different European sites. Blood samples from 172 of them were collected ≤ 6 h after trauma. Patients underwent a CT scan and were dichotomised into CT-positive and CT-negative groups for statistical analyses. H-FABP and S100B levels were measured using commercial kits, and their capacities to detect all CT-positive scans were evaluated, with sensitivity set to 100%. For patients recruited ≤ 6 h after trauma, the CT-positive group demonstrated significantly higher levels of both H-FABP (p = 0.004) and S100B (p = 0.003) than the CT-negative group. At 100% sensitivity, specificity reached 6% (95% CI 2.8-10.7) for S100B and 29% (95% CI 21.4-37.1) for H-FABP. Similar results were obtained when including all the patients recruited, i.e. hospital arrival within 24 h of trauma onset. H-FABP out-performed S100B and thus seems to be an interesting protein for detecting all CT-positive mTBI patients with a GCS score of 15 and at least one clinical symptom.

ABSTRACT

Biliary infections are a common cause of emergency department visit, usually of benign evolution but that can sometimes progress rapidly to a life-threatening emergency.The mainstay of treatment of acute cholecystitis is urgent laparoscopic cholecystectomy, performed in 72 hours.Antibiotic treatment is often sufficient for the initial treatment of mild cholangitis. A percutaneous or endoscopic biliary drainage must be done urgently in case of severe presentations or if the patient doesn't respond to conservative treatment. The definitive treatment of the cause of cholangitis, will be performed in a second time.


Les infections de la vésicule et des voies biliaires sont un motif fréquent de consultation aux urgences. Leur évolution est le plus souvent bénigne, mais elles peuvent parfois devenir rapidement une urgence vitale.Le pilier du traitement de la cholécystite aiguë est la cholécystectomie laparoscopique en urgence, réalisée dans un délai inférieur à 72 heures.L'antibiothérapie est souvent suffisante pour le traitement initial de Ia cholangite simple. Un drainage biliaire percutané ou endoscopique doit être effectué en urgence pour une cholangite sévère ou en cas de non-réponse au traitement conservateur. Le traitement définitif de la cause de la cholangite sera pratiqué dans un deuxième temps.

ABSTRACT

OBJECTIVES: To evaluate an algorithm integrating ultrasound and low-dose unenhanced CT with oral contrast medium (LDCT) in the assessment of acute appendicitis, to reduce the need of conventional CT. METHODS: Ultrasound was performed upon admission in 183 consecutive adult patients (111 women, 72 men, mean age 32) with suspicion of acute appendicitis and a BMI between 18.5 and 30 (step 1). No further examination was recommended when ultrasound was positive for appendicitis, negative with low clinical suspicion, or demonstrated an alternative diagnosis. All other patients underwent LDCT (30 mAs) (step 2). Standard intravenously enhanced CT (180 mAs) was performed after indeterminate LDCT (step 3). RESULTS: No further imaging was recommended after ultrasound in 84 (46%) patients; LDCT was obtained in 99 (54%). LDCT was positive or negative for appendicitis in 81 (82%) of these 99 patients, indeterminate in 18 (18%) who underwent standard CT. Eighty-six (47%) of the 183 patients had a surgically proven appendicitis. The sensitivity and specificity of the algorithm were 98.8% and 96.9%. CONCLUSIONS: The proposed algorithm achieved high sensitivity and specificity for detection of acute appendicitis, while reducing the need for standard CT and thus limiting exposition to radiation and to intravenous contrast media.

ABSTRACT

When should a patient with abdominal pain be referred to the emergency ward? The following goals must be achieved upon managing patients with acute abdominal pain: 1) identify vital emergency situations; 2) detect surgical conditions that require emergency referral without further diagnostic procedures; 3) in "non surgical acute abdomen patients" perform appropriate diagnostic procedures, or in selected cases delay tests and reevaluate the patient after an observation period, after which a referral decision is made. Clues from the history and physical examination are critical to perform this evaluation. A good knowledge of the most frequent acute abdominal conditions, and identifying potential severity criteria allow an appropriate management and decision about emergency referral.

ABSTRACT

CT delivers a large dose of radiation, especially in abdominal imaging. Recently, a low-dose abdominal CT protocol (low-dose CT) has been set-up in our institution. "Low-dose CT" is almost equivalent to a single standard abdominal radiograph in term of dose of radiation (about one sixth of those delivered by a standard CT). "Low-dose CT" is now used routinely in our emergency service in two main indications: patients with a suspicion of renal colic and those with right lower quadrant pain. It is obtained without intravenous contrast media. Oral contrast is given to patients with suspicion of appendicitis. "Low-dose CT" is used in the frame of well defined clinical algorithms, and does only replace standard CT when it can reach a comparable diagnostic quality.

ABSTRACT

INTRODUCTION: The aim of this study was to assess the outcome of surgery for rectal cancer in patients 80 years of age or more. METHODS: A retrospective study of 29 patients older than 80 years, who presented in our institution between 1997 and 2001 with the diagnosis of rectal adenocarcinoma, was undertaken. RESULTS: Median follow-up was 54 (range 27-78) months, and the median age of patients was 85 (range 80-94) years. Twenty-four out of 29 patients (83%) underwent surgery, 23 being operated electively. Twenty out of 24 patients (83%) underwent resection with curative intent, while four patients (17%) had a palliative procedure. Median hospital stay was 13 (range 10-35) days. Postoperative morbidity and mortality were 46% and 12.5%, respectively. However, when considering only elective procedures with curative intent, operative mortality was 5%. At the time of last follow-up, 13 patients were alive, five of them with no evidence of recurrent disease at 5 years, for an overall 2- and 5-year survival rate of 80% and 67%, respectively. Four out of the 7 deaths, which occurred after surgery, were due to medical causes unrelated to cancer. CONCLUSION: In our institution, two thirds of patients older than 80 years who presented with rectal cancer underwent surgery with curative intent. In this selected population, good results in terms of short-term survival can be achieved, at the price of an elevated postoperative morbidity. Whenever possible, treatment with curative intent should be considered in patients with rectal cancer, irrespective of the age.
