RESUMEN
BACKGROUND: Laparoscopy is widely adopted across nearly all surgical subspecialties in the elective setting. Initially finding indication in minor abdominal emergencies, it has gradually become the standard approach in the majority of elective general surgery procedures. Despite many technological advances and increasing acceptance, the laparoscopic approach remains underutilized in emergency general surgery and in abdominal trauma. Emergency laparotomy continues to carry a high morbidity and mortality. In recent years, there has been a growing interest from emergency and trauma surgeons in adopting minimally invasive surgery approaches in the acute surgical setting. The present position paper, supported by the World Society of Emergency Surgery (WSES), aims to provide a review of the literature to reach a consensus on the indications and benefits of a laparoscopic-first approach in patients requiring emergency abdominal surgery for general surgery emergencies or abdominal trauma. METHODS: This position paper was developed according to the WSES methodology. A steering committee performed the literature review and drafted the position paper. An international panel of 54 experts then critically revised the manuscript and discussed it in detail, to develop a consensus on a position statement. RESULTS: A total of 323 studies (systematic review and meta-analysis, randomized clinical trial, retrospective comparative cohort studies, case series) have been selected from an initial pool of 7409 studies. Evidence demonstrates several benefits of the laparoscopic approach in stable patients undergoing emergency abdominal surgery for general surgical emergencies or abdominal trauma. The selection of a stable patient seems to be of paramount importance for a safe adoption of a laparoscopic approach. In hemodynamically stable patients, the laparoscopic approach was found to be safe, feasible and effective as a therapeutic tool or helpful to identify further management steps and needs, resulting in improved outcomes, regardless of conversion. Appropriate patient selection, surgeon experience and rigorous minimally invasive surgical training, remain crucial factors to increase the adoption of laparoscopy in emergency general surgery and abdominal trauma. CONCLUSIONS: The WSES expert panel suggests laparoscopy as the first approach for stable patients undergoing emergency abdominal surgery for general surgery emergencies and abdominal trauma.

PURPOSE: Polytrauma is increasingly recognized as a disease beyond anatomical injuries. Due to population growth, centralization, and slow uptake of preventive measures, major trauma presentations in most trauma systems show a slow but steady increase. The proportional contribution of polytrauma patients to this increase is unknown. METHODS: A 13-year retrospective analysis ending 31/12/2021 of all major trauma admissions (ISS > 15) to a level-1 trauma center were included. Polytrauma was classified using the Newcastle definition. Linear regression analysis was used to compare the rates of patient presentation over time. Logistic regression was used to measure for change in proportion of polytrauma. Data are presented as median (IQR), with odds ratios and 95% confidence intervals as appropriate. RESULTS: 5897 (age: 49 ± 43 years, sex: 71.3% male, ISS: 20 ± 9, mortality: 10.7%) major trauma presentations were included, 1,616 (27%) were polytrauma (age: 45 ± 37 years, 72.0% male, ISS: 29 ± 14, mortality: 12.7%). Major trauma presentations increased significantly over the study period (+ 8 patients per year (3-14), p < 0.01), aged significantly (0.42 years/year (0.25-0.59, p < 0.001). The number of polytrauma presentations per year did not change significantly (+ 1 patients/year (- 1 to 4, p > 0.2). Overall unadjusted mortality did not change (OR 0.99 (0.97-1.02). Polytrauma mortality fell significantly (OR 0.96 (0.92-0.99)) over the study period. CONCLUSIONS: Polytrauma patients represent about 25% of the major trauma admissions, with higher injury severity, static incidence and higher but improving mortality in comparison to all major trauma patients. Separate reporting and focused research on this group are warranted as monitoring the entire major trauma cohort does not identify these specifics of this high acuity subgroup.
RESUMEN
PURPOSE: The risk of death after traumatic injury in developed trauma systems is at an all-time low. Among 'major trauma' patients (injury severity score, ISS > 15), the risk of dying is less than 10%. This group contains critical polytrauma patients (ISS 50-75), with high risks of death. We hypothesized that the reduction in trauma mortality was driven by reduction in moderate injury severity and that death from critical polytrauma remained persistently high. METHODS: A 20-year retrospective analysis ending December 2021 of a Level-1 trauma center's registry was performed on all trauma patients admitted with ISS > 15. Patients' demographics, injury severity and outcomes were collected. Multivariate logistic regression analysis was performed. Mortality was examined for the entire study group and separately for the subset of critical polytrauma patients (ISS 50-75). RESULTS: A total of 8462 severely injured (ISS > 15) trauma patients were identified during the 20-year period. Of these 238 (2.8%) were critical polytrauma patients (ISS 50-75). ISS > 15 mortality decreased from 11.3 to 9.4% over the study period (Adjusted OR 0.98, 0.97-0.99). ISS 50-75 mortality did not change significantly (46.2-60.0%), adjusted OR 0.96, 0.92-1.00). CONCLUSION: The improvement in trauma mortality over the past 20 years has not been experienced equally. The ISS50-75 critical polytrauma mortality is a practical group to capture. It could be a group for deeper study and reporting to drive improvement.
RESUMEN
PURPOSE: We hypothesized that unrestricted or full weight-bearing (FWB) in hip fracture would increase the opportunity to mobilize on post-operative day 1 (POD1mob) and be associated with better outcomes compared with restricted weight-bearing (RWB). METHODS: Over 4 years, 1514 geriatric hip fracture patients aged 65 and above were prospectively recruited. Outcomes were compared between FWB and RWB patients. The primary outcome was 30-day mortality. Secondary outcomes were immobility-related adverse events, length of stay (LOS), and reoperation for failure. Causal effect modelling and multivariate regression with mediation analyses were performed to examine the relation between weight-bearing status (WBS), POD1mob, and known mortality predictors. RESULTS: FWB was allowed in 1421 (96%) of 1479 surgically treated patients and RWB enforced in 58 (4%) patients. Mortality within 30 days occurred in 141 (9.9%) of FWB and 3 (5.2%) of RWB patients. In adjusted analysis, RWB did not influence 30-day mortality (OR 0.42, 95% CI 0.15-01.13, p = 0.293), with the WBS accounting for 91% of the total effect on mortality and 9% contributed from how WBS influenced the POD1mob. RWB was significantly related to increased DVT (OR 7.81, 95% CI: 1.81-33.71 p = 0.002) but no other secondary outcomes. Patients that did not have the opportunity to mobilize had increased 30-day mortality (OR 2.31, 95% CI 1.53-3.48 p < 0.001). CONCLUSION: Restricted weight-bearing was not associated with increased 30-day mortality. Only a small proportion of this effect was mediated by POD1mob. Whilst post-surgical WBS may be difficult to influence for cultural reasons, POD1mob is an easily modifiable target that is likely to have a greater effect on 30-day mortality. LEVEL OF EVIDENCE: Level III, observational study.

PURPOSE: Angioembolization (AE) has been questioned as first-line modality for hemorrhage control of pelvic fracture (PF)-associated bleeding due to its potential inconsistent timely availability. We aimed to describe the patterns of AE use with hemostatic resuscitation and hypothesized that time to AE improved during the study period. METHODS: A Level-1 trauma center's prospective PF database was analyzed. All consecutive PFs referred to angiography between 01/01/2009 and 12/31/2018 were included. All suspected pelvic hemorrhage was managed with AE; pelvic packing was not performed. Demographics, injury/shock severity, 24-h transfusion data, time to AE and mortality were recorded. Data are presented as median (IQR). RESULTS: During the 10-year study period, 1270 PF patients were treated. Thirty-six (2.8%) [75% male, 49 (33;65) years, ISS 36 (24;43), base deficit 3.65 (5.9;0.6), transfusions 4(2;7)] had AE. The indication for AE was clinical suspicion (CS) of pelvic bleeding [CS 24(67%)] or arterial blush on CT [CT 12 (33%)]. Median time to AE was 141 min for CS, and 223 min for CT, with no change over the study period. Patients with CS had a higher ISS, worse base deficit, greater transfusion requirements and faster time to AE. Five patients (14%) died. There were no deaths attributed to exsanguination. CONCLUSIONS: Time to AE did not improve. Patients referred from CT are physiologically different from CS and should be analyzed accordingly, with CS resulting in faster time to AE in sicker patients. Contemporary resuscitation challenges the need for hyperacute AE as no patients exsanguinated despite time to AE of more than 2 h.

Deciding whether to delay non-lifesaving orthopaedic trauma surgery to prevent multiple organ failure (MOF) or sepsis is frequently disputed and largely based on expert opinion. We hypothesise that neutrophils and monocytes differentially express activation markers prior to patients developing these complications. Peripheral blood from 20 healthy controls and 162 patients requiring major orthopaedic intervention was collected perioperatively. Neutrophil and monocyte L-selectin, CD64, CD11, CD18, and CXCR1 expression were measured using flow cytometry. The predictive ability for MOF and sepsis was assessed using the Receiver Operating Characteristic (ROC) comparing to C-reactive protein (CRP). Neutrophil and monocyte L-selectin were significantly higher in patients who developed sepsis. Neutrophil L-selectin (AUC 0.692 [95%CI 0.574-0.810]) and monocyte L-selectin (AUC 0.761 [95%CI 0.632-0.891]) were significant predictors of sepsis and were not significantly different to CRP (AUC 0.772 [95%CI 0.650-0.853]). Monocyte L-selectin was predictive of MOF preoperatively and postoperatively (preop AUC 0.790 [95%CI 0.622-0.958]). CD64 and CRP were predictive of MOF at one-day postop (AUC 0.808 [95%CI 0.643-0.974] and AUC 0.809 [95%CI 0.662-0.956], respectively). In the perioperative period, elevated neutrophil and monocyte L-selectin are predictors of postoperative sepsis. Larger validation studies should focus on these biomarkers for deciding the timing of long bone/pelvic fracture fixation.
RESUMEN
PURPOSE: Prehospital guidelines stratify and manage patients with Glasgow Coma Scale (GCS) less than nine and any sign of head injury as affected by severe traumatic brain injury (STBI). We hypothesized that this group of patients is so inhomogeneous that uniform treatment guidelines cannot be advocated. METHODS: Patients (2005-2012) with prehospital GCS below nine and abbreviated injury scale head and neck above two were identified from trauma registry. Patients with acute lethal injuries, isolated neck injuries, extubated within 24 h or transferred interhospitally were excluded. Patients were dichotomized based on the worst prehospital GCS (recorded before sedatives) into two groups: GCS 3-5 and GCS 6-8. These were statistically compared using univariate analysis. RESULTS: The GCS 3-5 group (99 patients) when compared with the GCS 6-8 group (49 patients) had shorter prehospital times (63 vs. 79 min; p < 0.05), more frequent episodes of both hypoxia (30.3% vs. 7.7%; p < 0.05) and hypotension (26.7% vs. 6.4%; p < 0.05), more often required craniectomy (15.1% vs. 4.0%; p = 0.05) and higher mortality (33.3% vs. 2%; p < 0.05). In the GCS 3-5 group, prehospital endotracheal intubation was attempted more often (57.5% vs. 28.6%, p < 0.05) and was more often successful (39.3% vs. 10.2%; p = 0.05). Length of stay in ICU did not differ. CONCLUSIONS: STBI patients are fundamentally different based on whether their initial GCS falls into 3-5 or 6-8 category. Recommendations from trials investigating trauma patients with GCS less than nine as one group should be translated with caution to clinical practice.

Mitochondria play a key role in the pathophysiology of post-injury inflammation. Cell-free mitochondrial DNA (cf-mtDNA) is now understood to catalyse sterile inflammation after trauma. Observations in trauma cohorts have identified high cf-mtDNA in patients with systemic inflammatory response syndrome and multiple organ failure as well as following major surgery. The source of cf-mtDNA can be various cells affected by mechanical and hypoxic injury (passive mechanism) or induced by inflammatory mechanisms (active mechanism). Multiple forms of cf-mtDNA exist; mtDNA fragments, mtDNA in microparticles/vesicles and cell-free mitochondria. Trauma to cells that are rich in mitochondria are believed to release more cf-mtDNA. This review describes the current understanding of the mechanisms of cf-mtDNA release, its systemic effects and the potential therapeutic implications related to its modification. Although current understanding is insufficient to change trauma management, focussed research goals have been identified to pave the way for monitoring and manipulation of cf-mtDNA release and effects in trauma.
