Review of Traumatic Duodenal Injuries: Etiology, Diagnosis, and Management

Traumatic duodenal injuries are rare and often challenging to diagnose and treat. Management of these injuries remains controversial and continues to evolve. Here, we performed a review of the literature and guidelines for the diagnosis and management of traumatic duodenal injuries. A common recommendation in more recent literature is primary, tension-free repair of duodenal injuries when possible if surgical repair is necessary. Conversely, if duodenal injuries are unamenable to primary repair, more complex procedures such as Roux-en-Y duodenojejunostomy or pancreaticoduodenectomy may be necessary. Regardless of injury grade or type of surgical repair, the literature continues to support wide extraluminal drainage. Over time, the management of complex duodenal injuries has evolved to favor simple primary repair whenever possible. According to recent studies, more complex procedures are associated with higher rates of post-operative complications and should be reserved for severe injuries when primary repair is not possible.

Outcomes of grafted skin on the dorsum of the foot after car-tire friction injuries

Background A car-tire friction injury on the dorsum of a child’s foot often results in hypertrophic scarring of the wound margins. This study describes the clinical appearance of the injured areas and surgical complications that occurred during the follow-up period in a series of children with car-tire friction injuries who were treated with split-thickness skin grafts (STSGs). We describe the clinical features that we believe need to be highlighted when initially treating car-tire injuries in children.Methods From May 2003 to June 2016, our retrospective study included 15 patients with car-tire injuries on the dorsum of the foot who were treated with surgical excision and STSG to cover the wound.Results A total of 15 patients with car-tire injuries were treated. The average age was 6.26 years old. The average injury grade was 3.26. Two patients were treated using delayed repair, and 13 patients received STSG for initial management. Four patients experienced no complications, while 11 patients had hypertrophic scars and/or scar contracture after surgery.Conclusions A car-tire friction injury on the dorsum of a child’s foot often results in hypertrophic scar formation or scar contracture even if proper management is undertaken. Since the occurrence of these complications in childhood can lead to a secondary deformity, it is important to properly treat car-tire friction wounds, inform patients and caregivers about potential complications, and ensure regular follow-up evaluations over a 12-month period following the initial surgery.

Importance of a Follow-Up Ultrasound Protocol in Monitoring Posttraumatic Spleen Complications in Children Treated with a Non-Operative Management

Background and objectives: For the last three decades, non-operative management (NOM) has been the standard in the treatment of clinically stable patients with blunt spleen injury, with a success rate of up to 95%. However, there are no prospective issues in the literature dealing with the incidence and type of splenic complications after NOM. Materials and methods: This study analyzed 76 pediatric patients, up to the age of 18, with blunt splenic injury who were treated non-operatively. All patients were included in a posttraumatic follow-up protocol with ultrasound examinations 4 and 12 weeks after injury. Results: The mean age of the children was 9.58 ± 3.97 years (range 1.98 to 17.75 years), with no statistically significant difference between the genders. The severity of the injury was determined according to the American Association for Surgery of Trauma (AAST) classification: 7 patients had grade I injuries (89.21%), 21 patients had grade II injuries (27.63%), 33 patients had grade III injuries (43.42%), and 15 patients had grade IV injuries (19.73%). The majority of the injuries were so-called high-energy ones, which were recorded in 45 patients (59.21%). According to a previously created posttraumatic follow-up protocol, complications were detected in 16 patients (21.05%). Hematomas had the highest incidence and were detected in 11 patients (14.47%), while pseudocysts were detected in 3 (3.94%), and a splenic abscess and pseudoaneurysm were detected in 1 patient (1.31%), respectively. The complications were in a direct correlation with injury grade: seven occurred in patients with grade IV injuries (9.21%), five occurred in children with grade III injuries (6.57%), three occurred in patients with grade II injuries (3.94%), and one occurred in a patient with a grade I injury (1.31%). Conclusion: Based on the severity of the spleen injury, it is difficult to predict the further course of developing complications, but complications are more common in high-grade injuries. The implementation of a follow-up ultrasound protocol is mandatory in all patients with NOM of spleen injuries for the early detection of potentially dangerous and fatal complications.

Clinical Features and Outcomes Based on Liver Injury Patterns in Liver Injury Caused by Immune Checkpoint Inhibitors

BackgroundThe clinical course of liver injury induced by immune checkpoint inhibitors (ICIs) varies among individuals, and there were few reports on the therapeutic effects of corticosteroids based on the patterns of liver injury.MethodsWe evaluated the characteristics and clinical course of immune-related liver injury in 1087 patients treated with ICIs for advanced malignancies between August 2014 and December 2020. ResultsDuring the follow-up period (median, 270 days), 56 patients (5.2%) had immune-related liver injury (≥Grade 3). The liver-injury patterns were hepatocellular (n = 25, 44.6%), mixed (n = 10, 17.9%), or cholestatic (n = 21, 37.5%), and the median time to onset of liver injury was 36, 85, and 53 days, respectively; the hepatocellular pattern occurred earlier than the other types (P = 0.036). Corticosteroids were administered to 29 (51.8%) patients. While liver injury was improved in almost all patients with the hepatocellular pattern (n = 13/14, 92.9%), that failed to show improvement in over half of the patients with the non-hepatocellular patterns (mixed, n = 8; cholestatic, n = 7), and three patients with mixed patterns needed secondary immunosuppression with mycophenolate mofetil. Liver biopsies performed in 13 patients mainly showed lobular injury, endothelialitis, and spotty necrosis with infiltration of T cells positive for CD3 and CD8, but not CD4 or CD20. ConclusionThe incidence pattern and therapeutic response to corticosteroids in immune-related liver injury differs according to the injury type. Although corticosteroids were effective for the hepatocellular pattern, an additional strategy for refractory non-hepatocellular patterns is needed.

Aspirin versus anticoagulation for stroke prophylaxis in blunt cerebrovascular injury: a propensity-matched retrospective cohort study

OBJECTIVE The goal of this study was to compare the odds of stroke 24 hours or more after hospital arrival among patients with blunt cerebrovascular injury (BCVI) who were treated with therapeutic anticoagulation versus aspirin. METHODS The authors conducted a retrospective cohort study at a regional level I trauma center including all patients with BCVI who were treated over a span of 10 years. Individuals with stroke on arrival or within the first 24 hours were excluded, as were those receiving alternative antithrombotic drugs or procedural treatment. Exact logistic regression was used to examine the association between treatment and stroke, adjusting for injury grade. To account for the possibility of residual confounding, propensity scores for the likelihood of receiving anticoagulation were determined and used to match patients from each treatment group; the difference in the probability of stroke between the two groups was then calculated. RESULTS A total of 677 patients with BCVI receiving aspirin or anticoagulation were identified. A total of 3.8% (n = 23) of 600 patients treated with aspirin sustained a stroke, compared to 11.7% (n = 9) of 77 receiving anticoagulation. After adjusting for injury grade with exact regression, anticoagulation was associated with higher likelihood of stroke (OR 3.01, 95% CI 1.00–8.21). In the propensity-matched analysis, patients who received anticoagulation had a 15.0% (95% CI 3.7%–26.3%) higher probability of sustaining a stroke compared to those receiving aspirin. CONCLUSIONS Therapeutic anticoagulation may be inferior to aspirin for stroke prevention in BCVI. Prospective research is warranted to definitively compare these treatment strategies.

Inpatient and Postdischarge Outcomes Following Inhalation Injury Among Critically Injured Burn Patients

Inhalation injury is associated with high inpatient mortality, but the impact of inhalation injury after discharge and on non-mortality outcomes is poorly characterized. To address this gap, we evaluated the effect of inhalation injury on postdischarge morbidity, mortality, and hospital readmissions among patients who sustained burn injury, as well as on in-hospital outcomes for context. This was a retrospective cohort study of patients with cutaneous fire/flame burns admitted to a burn center intensive care unit from January 1, 2009 to December 31, 2015, with or without inhalation injury. Records were linked to statewide hospital admission and vital statistics databases to assess postdischarge outcomes. Mixed-effects Poisson regression was used to assess mortality, complications, and readmissions. The overall cohort included 830 patients with cutaneous burns; of these, 201 patients had inhalation injury. In-hospital mortality was 31% among inhalation injury patients vs 6% in patients without inhalation injury (adjusted OR 2.35; 95% CI 1.66–3.31). Inhalation injury was also associated with an increased risk of in-hospital pneumonia and tracheostomy (P < .05 for all). Inhalation injury was not associated with greater postdischarge mortality, all-cause readmission, readmission for pulmonary diagnosis, or readmission requiring intubation. Among the subset of patients with bronchoscopy-confirmed inhalation injury (n = 124; 62% of inhalation injuries), a higher injury grade was not associated with greater inpatient or postdischarge mortality. Inhalation injury was associated with increased early morbidity and mortality, but did not contribute to postdischarge mortality or readmission. These findings have implications for shared decision making with patients and families and for estimating healthcare utilization after initial hospitalization.
