Abstract PDF: Purpose
To determine the incidence and risk factors of postoperative infection after cranioplasty in patients with traumatic brain injury (TBI).
Methods
Data of 289 adult patients who underwent cranioplasty after TBI at a single regional trauma center between year 2018 and 2021 were reviewed retrospectively. Patient characteristics and various procedural variables, such as interval between craniectomy and cranioplasty, estimated blood loss, laterality and materials of the bone flap, and duration and classification of perioperative antibiotics usage were analyzed.
Results
Postoperative infection occurred in 17 patients (5.9%). Onset time of infectious symptom ranged from 9 days to 174 days (median, 24 days) after cranioplasty. The most common cultured organism was Staphylococcus aureus (47.1%), followed by Klebsiella pneumoniae (17.6%) and Enterococcus faecalis (17.6%). Patients with postoperative infection were more likely to have diabetes (odds ratio [OR], 6.96; 95% confidence interval [CI], 1.92–25.21; P=0.003), lower body mass index (OR, 0.81; 95% CI, 0.66–0.98; P=0.029), and shorter duration of perioperative antibiotics (OR, 0.83; 95% CI, 0.71–0.98; P=0.026).
Conclusions
For TBI patients with diabetes, poor nutritional status should be managed cautiously for increased risk of infection after cranioplasty. Further studies and discussions are needed to determine an appropriate antibiotics protocol in cranioplasty.; Summary

Abstract PDF: Gastric artery bleeding after blunt trauma is rare. In such cases, if vital signs are stable, angiographic embolization may be performed. Although gastric artery embolization is known to be safe due to its anatomical properties, complications may occur. We report a case of gastric necrosis after gastric artery embolization in a patient with blunt abdominal trauma. The 55-year-old male patient was found with gastric arterial bleeding after a traffic accident. His vital signs were stable, and gastric artery embolization was performed. Gastric necrosis was subsequently found, which was treated surgically.; Summary

Abstract PDF: Purpose
The neck is a particularly critical region for penetrating injuries due to the close proximity of the trachea, esophagus, blood vessels, and the spinal cord. An open neck injury has the potential for serious morbidity and mortality. The purpose of this study is to evaluate the assessment and management of open neck injuries.
Methods
In this retrospective study, open neck injury patients who were admitted to NAME University Hospital Trauma Center between December 2015 and December 2017 were analyzed for epidemiology, the mechanism of trauma, the injured organ, complications, and mortality.
Results
Thirty-two patients presented with open neck injuries. All patients underwent computed tomographic angiography to evaluate their injuries once their vital signs stabilized. Among these patients, 27 required surgical treatment. The most commonly injured organ was the airway. There were five deaths, and the main cause of death was bleeding. Mortality was associated with the initial systolic blood pressure at the hospital and Glasgow Coma Scale.
Conclusions
Mortality from open neck injuries was associated with initial systolic blood pressure at the hospital and Glasgow Coma Scale.; Summary

Abstract PDF: This paper aims to summarize why I write, how to find a motif, and how to polish and finish a manuscript. For William Carlos Williams, practicing medicine and writing poetry were two parts of a single whole, not each of the other. The two complemented each other. Medicine stimulated Williams to become a poet, while poetry was also the driving force behind his role as a doctor. Alexander Pope, the 18th century English poet, wrote a poem entitled “The Epistle to Dr. Arbuthnot” that was dedicated to a friend who was both a poet and a physician. In this poem, we receive an answer to the questions of ‘‘Why do you write? Why do you publish?’’ Pope writes, “Happy my studies, when by these approv’d! / Happier their author, when by these belov’d! / From these the world will judge of men and books.” When I write, I first reflect on whether I only want to write something for its own sake, like “a dog chasing its own tail,’’ instead of making a more worthwhile contribution. When my colleagues ask me, “Why do you write essays as well as scientific papers?” I usually answer, “Writing is a process of healing for me—I cannot bear myself unless I write.” When the time comes to sit down and put pen to paper, I remind myself of the saying, festina lente (in German, Ohne Hast, aber ohne Rast, corresponding to the English proverb “more haste, less speed”). If I am utterly exhausted when I finish writing, then I know that I have had my vision.; Summary

Purpose
The scoring system for traumatic liver injury (SSTLI) was developed in 2015 to predict mortality in patients with polytraumatic liver injury. This study aimed to validate the SSTLI as a prognostic factor in patients with polytrauma and liver injury through a generalized estimating equation analysis. Methods: The medical records of 521 patients with traumatic liver injury from January 2015 to December 2019 were reviewed. The primary outcome variable was in-hospital mortality. All the risk factors were analyzed using multivariate logistic regression analysis. The SSTLI has five clinical measures (age, Injury Severity Score, serum total bilirubin level, prothrombin time, and creatinine level) chosen based on their predictive power. Each measure is scored as 0–1 (age and Injury Severity Score) or 0–3 (serum total bilirubin level, prothrombin time, and creatinine level). The SSTLI score corresponds to the total points for each item (0–11 points). Results: The areas under the curve of the SSTLI to predict mortality on post-traumatic days 0, 1, 3, and 5 were 0.736, 0.783, 0.830, and 0.824, respectively. A very good to excellent positive correlation was observed between the probability of mortality and the SSTLI score (γ=0.997, P<0.001). A value of 5 points was used as the threshold to distinguish low-risk (<5) from high-risk (≥5) patients. Multivariate analysis using the generalized estimating equation in the logistic regression model indicated that the SSTLI score was an independent predictor of mortality (odds ratio, 1.027; 95% confidence interval, 1.018–1.036; P<0.001). Conclusions: The SSTLI was verified to predict mortality in patients with polytrauma and liver injury. A score of ≥5 on the SSTLI indicated a high-risk of post-traumatic mortality.

Abstract PDF

The most common cause of foot drop is lumbar degenerative disc herniation, particularly at L4/5. We present a rare case of spinal cord injury accompanied by a thoracolumbar lesion that presented with bilateral foot drop. A 69-year-old male patient presented with sudden-onset severe bilateral leg pain and bilateral foot drop. Radiologic findings revealed T12 spondylitis compressing the conus medullaris. He had undergone vertebroplasty for a T12 compression fracture after a fall 6 months before. A physical examination showed bilateral foot drop, paresthesia of both L5 dermatomes, increased deep tendon reflex, and a positive Babinski sign. An acute bilateral L5 root lesion and a conus medullaris lesion were suspected based on electromyography. A surgical procedure was done for decompression and reconstruction. After the operation, bilateral lower extremity muscle strength recovered to a good grade from the trace grade, and the patient could walk without a cane. The current case is a very rare report of bilateral foot drop associated with T12 infectious spondylitis after vertebroplasty. It is essential to keep in mind that lesions of the thoracolumbar junction can cause atypical neurological symptoms. Furthermore, understanding the conus medullaris and nerve root anatomy at the T12–L1 level will be helpful for treating patients with atypical neurological symptoms.

Abstract PDF: Comminuted fractures of the patella mostly occur at the inferior pole and require appropriate reduction and fixation to restore the extensor mechanism. Conventional methods such as tension-band wiring are not enough to gain proper fixation strength. Numerous methods have been reported, including circumferential cerclage wiring, osteosynthesis, and suture anchors depending on the fracture pattern. Herein, the author reports a relatively rare case of a comminuted fracture of the upper pole of the patella, for which we used augmented Krackow sutures in the quadriceps and fixation with tying of the suture limbs through patellar bone tunnels. Satisfactory results were obtained in terms of reduction and extensor mechanism recovery.; Summary

Abstract PDF: We report a case of delayed chest wall reconstruction after thoracotomy. A 53-year-old female, a victim of a motor vehicle accident, presented with bilateral multiple rib fractures with flail motion and multiple extrathoracic injuries. Whole-body computed tomography revealed multiple fractures of the bilateral ribs, clavicle, and scapula, and bilateral hemopneumothorax with severe lung contusions. Active hemorrhage was also found in the anterior pelvis, which was treated by angioembolization. The patient was transferred to the surgical intensive care unit for follow-up. We planned to perform surgical stabilization of rib fractures (SSRF) because her lung condition did not seem favorable for general anesthesia. Within a few hours, however, massive hemorrhage (presumably due to coagulopathy) drained through the thoracic drainage catheter. We performed an exploratory thoracotomy in the operating room. We initially planned to perform exploratory thoracotomy and “on the way out” SSRF. In the operating room, the hemorrhage was controlled; however, her condition deteriorated and SSRF could not be completed. SSRF was completed after about a month owing to other medical conditions, and the patient was weaned successfully.; Summary

Abstract PDF

The aim of this review is to introduce the progress in trauma surgery made during war. In the 16th century, Paré reintroduced ligature of arteries, which had been introduced by Celsus and Galen, instead of cauterization during amputation. Larrey, a surgeon in Napoleon’s military, adapted the “flying artillery” to serve as “flying ambulances” for rapid transport of the wounded. He established rules for the triage of war casualties, treating wounded soldiers according to the seriousness of their injuries and the urgency of medical care. To treat fractures and tuberculosis, Thomas created the “Thomas splint”, which was used to stabilize fractured femurs and prevent infection; in World War I (WWI), use of this splint reduced the mortality of compound femur fractures from 87% to less than 8%. During WWI, Cushing systematized the treatment of head injuries, reducing mortality among head injury patients. Gillies repaired facial injuries, and his experiences became the basis of craniofacial and aesthetic surgery. In WWII, McIndoe discovered that immersion in saline promoted burn healing and improved survival rates, and thus began saline baths and early grafting instead of using tannic acid. A high mortality rate in patients with acute renal failure was noted in WWII and the Korean War. In the Korean War, Teschan used the Kolff-Brigham dialyzer. The first use of medevac with helicopters was the evacuation of three British pilot combat casualties by the US Army in Burma during WWII. As a lotus blooms in the mud, military surgeons have contributed to trauma surgery during wartime.

Abstract PDF

Purpose

The coronavirus disease 2019 (COVID-19) pandemic has necessitated a redistribution of resources to meet hospitals’ service needs. This study investigated the impact of COVID-19 on a regional trauma center in South Korea.

Methods

We retrospectively reviewed cases of polytrauma at a single regional trauma center in South Korea between January 20 and September 30, 2020 (the COVID-19 period) and compared them to cases reported during the same time frame (January 20 to September 30) between 2016 and 2019 (the pre-COVID-19 period). The primary outcome was in-hospital mortality, and secondary outcomes included the number of daily admissions, hospital length of stay (LOS), and intensive care unit (ICU) LOS.

Results

The mean number of daily admissions decreased by 15% during the COVID-19 period (4.0±2.0 vs. 4.7±2.2, p=0.010). There was no difference in mechanisms of injury between the two periods. For patients admitted during the COVID-19 period, the hospital LOS was significantly shorter (10 days [interquartile range (IQR) 4–19 days] vs. 16 days [IQR 8–28 days], p<0.001); however, no significant differences in ICU LOS and mortality were found.

Conclusions

The observations at Regional Trauma Center, Pusan National University Hospital corroborate anecdotal reports that there has been a decline in the number of patients admitted to hospitals during the COVID-19 period. In addition, patients admitted during the COVID-19 pandemic had a significantly shorter hospital LOS than those admitted before the COVID-19 pandemic. These preliminary data warrant validation in larger, multi-center studies.

Abstract PDF

Purpose

To evaluate the severity of trauma, many scoring systems and predictive models have been presented. The quick Sequential Organ Failure Assessment (qSOFA) is a simple scoring system based on vital signs, and we expect it to be easier to apply to trauma patients than other trauma assessment tools.

Methods

This study was a cross-sectional study of trauma patients who visited the emergency department of Jeju National University Hospital. We excluded patients under the age of 18 years and unknown outcomes. We calculated the qSOFA, the Modified Early Warning Score (mEWS), Revised Trauma Score (RTS), and Injury Severity Score (ISS) based on patients’ initial vital signs and assessments performed in the emergency department (ED). The primary outcome was mortality within 14 days of trauma. We analyzed qSOFA scores using multivariate logistic regression analysis and compared the predictive accuracy of these scoring systems using the area under the receiver operating characteristic curve (AUROC).

Results

In total, 27,764 patients were analyzed. In the multivariate logistic regression analysis of the qSOFA, the adjusted odds ratios with 95% confidence interval (CI) for mortality relative to a qSOFA score of 0 were 27.82 (13.63–56.79) for a qSOFA score of 1, 373.31 (183.47–759.57) for a qSOFA score of 2, and 494.07 (143.75–1698.15) for a qSOFA score of 3. In the receiver operating characteristic (ROC) curve analysis for the qSOFA, mEWS, ISS, and RTS in predicting the outcomes, for mortality, the AUROC for the qSOFA (AUROC [95% CI]; 0.912 [0.871–0.952]) was significantly greater than those for the ISS (0.700 [0.608–0.793]) and RTS (0.160 [0.108–0.211]).

Conclusions

The qSOFA was useful for predicting the prognosis of trauma patients evaluated in the ED.
