PURPOSE
The establishment of the trauma system has changed the quality of trauma care in many countries. As one of the first designated level I trauma centers in Korea, we hypothesized that there were changes in laparotomy patterns and subsequent survival rates after the center was established.
METHODS
This was a 5-year retrospective study of all severe hemoperitoneum patients who were transfused with more than 10 units of packed red blood cells (RBCs) within 24 h of hospitalization. Variables related to trauma were collected throughout the study period, and the patients admitted before (period 1) and after (period 2) the establishment of a trauma center were compared.
RESULTS
Forty-five patients were managed from January 2009 to March 2015. The baseline patient characteristics of the two groups, including age, Injury Severity Score, blood pressure, and hemoglobin levels, were similar. The time to the operating room (OR) was 144.3±51.5 min (period 1) and 79.9±44.1 min (period 2) (p<0.0001). Damage control surgery (DCS) was performed in 17% of patients during period 1 and in 73% during period 2. The number of actual survivors (n=10) was higher than expected (n=8) in period 2.
CONCLUSION
This is the first study analyzing the impact of a trauma center on the management of specific injuries, such as severe hemoperitoneum, in patients in Korea. During the study, the time to OR was shortened and DCS was used to a greater extent as a surgical procedure.

PURPOSE
Two years have passed since a level I trauma center was officially opened in the Gacheon Gil Hospital, South Korea. We analyzed 2014 and 2015 registered patient data from the Korean Trauma Data Base (KTDB) to identify trends in trauma patient care and factors that influence the quality of trauma care at the Gacheon Gil trauma center.
METHODS
Data was extracted from the KTDB included patient age, sex, systolic blood pressure at emergency room arrival, revised trauma score, injury severity score, trauma injury severity score, transfusion amount, and the cause of death was analyzed.
RESULTS
A total of 3269 trauma patients were admitted to our trauma center in 2014 and 3225 in 2015. Demographics and mechanism of injury were not significantly different between years. The severity of trauma injury was decreased in 2015 although the mortality rate was slightly increased. This requires further analysis.
CONCLUSION
The aim of this study was to determine the general status and trends in trauma incidence and management outcomes for the Incheon area. We noted no significant changes in trauma status from 2014 to 2015. We need to collect and review trauma patient data over a long period in order to elucidate trauma incidence and management trends in the trauma field. Finally, studies using trauma patient data will indicate appropriate quality control factors for trauma care and help to improve the quality of trauma management.

AbstractAbstract PDF
Traumatic diaphragmatic injury (TDI) occurs in 1% of patients of blunt abdominal trauma. Most TDIs involve the left diaphragm, however the authors experienced TDI accompanied by a liver laceration of the right diaphragm. When detected early, TDI can be easily treated, however serious complications can occur if not. When diaphragmatic injury is suspected due to clinical manifestation, comprehensive analysis of the patient data including radiologic findings is important.

AbstractAbstract PDF
Blunt traumatic vertebral artery injury (TVAI) is relatively rare, but it may frequently be associated with head and neck trauma. TVAI is difficult to diagnose with diverse outcomes, thus it is a clinical challenge. There are no widely accepted guidelines for treatment and diagnosis, so that the diagnosis of TVAI can be easily delayed. Therefore, any clinical suspicion from clues on the initial imaging is important for diagnosis of TVAI. The authors report on the case of a patient diagnosed as having a TVAI with a transverse foramen fracture.

PURPOSE
Establishment of the trauma system changed quality of trauma care in many countries. As one of the first designated level 1 trauma center in Korea, we analyzed trauma registration data in 2014.
METHODS
Data was extracted from Korean Trauma Data Base (KTDB) that was started from august 2013. Variables related to demographics and trauma was collected through the year 2014.
RESULTS
There were 3269 trauma patients who admitted to our hospital and registered to KTDB in 2014. Median age was 49 years, 64.4% were men, and 90% of patients were blunt in mechanism. Median injury severity score (ISS) was 5, mean revised trauma score (RTS) was 7.65. There were 138 (4.2%) deaths and 87 (2.7%) patients of them was death after admission.
CONCLUSION
This is the first report using KTDB registration from our institution. Trauma volume is appropriate but it should be compared with other trauma centers in Korea. In future national analysis of KTDB is mandatory.

AbstractAbstract PDF
PURPOSE
The first regional trauma center selected in Korea was the Gachon University Gil hospital regional trauma center; expectation on its role has been high because of its location in the Seoul metropolitan region. To determine if those expectations are being met, we analyzed the patients visiting the center and their treatment experiences for the past 3 years in order to propose a standard for the operation of a trauma center.
METHODS
The visiting route, visiting methods, performance of emergency surgery, the ward and the length of stay, the injury mechanism, the injury severity score (ISS), the department that managed the surgery, and the cause of death were analyzed for 367 patients visiting the center from its establishment in June 2011 through December 2013.
RESULTS
The mean age of the patients was 47 years (285 male and 82 female patients). A total of 187 patients directly visited the center whereas 180 were transferred to the center. Traffic accidents comprised the majority of injury mechanisms, and 178 patients underwent emergency surgery. The mean length of stay per patient was 11 days for those in the ICU and 27 days for those in a general ward. These patients occupied 4 beds in the ICU and 10 beds in the general ward per day. A total of 1.21 surgeries were performed per patient, and the mean number of surgeries performed per day was 0.49. The mean ISS was 15.91, and 183 patients (50%) had an ISS of > or =16. Thirty-one patients died; they had a mean ISS of 28.42. The most frequent cause of death was multi-organ failure. The mean number of treatment consultations during a patient's stay was 6.32. Forty-five patients (13%) were discharged from the center, and 291 (79%) were transferred to another hospital.
CONCLUSION
A systematic approach to establishing a treatment model for trauma patients, including injury mechanism, multidisciplinary treatment, and trauma surgeon intervention, is required for treating trauma patients.
Summary
Traumatic Lumbar Hernia: Report of a Case
Gil Jae Lee, Min Chung, Byung Chul Yu
J Trauma Inj. 2013;26(3):222-225.

AbstractAbstract PDF
The occurrence of traumatic hernia is rare. However, traumatic lumbar hernias are the most frequently occurring traumatic hernias. Superior lumbar hernias occur more frequently than inferior lumbar hernias, but for anatomical reasons, among traumatic lumbar hernias, inferior lumbar hernias occur more frequently than superior lumbar hernias. Repair of a lumbar hernia is very difficult. Mesh fixation to the bony part and general weakness of surrounding tissue make repair of a lumbar hernia tricky. A traumatic lumbar hernia was repaired using transfascial fixation around the defect to secure the mesh. This technique is another choice for a lumbar hernia technique.

AbstractAbstract PDF
PURPOSE
The base deficit (BD) at admission in severely injured patients has been shown to predict the adequacy of resuscitation and outcome, but this relationship is not well established in the Korean experience. The purpose of this study was to define the association between arterial blood gas (ABG) values and the mortality for patients with severe blunt trauma at a developing trauma center in Korea.
METHODS
A retrospective review of 415 adult patients with severe blunt trauma was conducted using electronic medical records from Jan. 2010 to Dec. 2011.
RESULTS
A total of 256 patients had ABG drawn within 1 hour of arrival. Patients who expired displayed a higher lactate level (4.86 vs. 3.31, p<0.0001), a worse BD (-7.99 vs. -5.37, p=0.001), and a lower pH (7.31 vs. 7.34, p=0.011) at arrival compared with those who survived. A statistically significant association was also observed between BD and blood product usage (p=0.001).
CONCLUSION
The base deficit at admission is a useful marker of mortality and outcome in severely injured patients with blunt trauma in Korea.

AbstractAbstract PDF
Resection of the bowel is necessary for the repair of a ventral hernia after recovery from trauma in some cases. In such instances, polyester or polypropylene meshcannot be used due to the possibility of infection; we had to use biological mesh instead. We report a case in which a traumatic hernia was repaired with Permacol (Covidien, Norwalk, CT, USA). A 42-year-old male patient had been injured by a factory machine seven months prior to admission. At that time, he had abdominal wall injury and small bowel perforation. His abdominal wall had been a defect after operation. A CT scan of the abdomen showed that the left abdominal wall, which is lateral to left rectus abdominis muscle had only one muscle layer, an external oblique muscle, and that a previous abdominal incision had a defect along the entire incision. During the exploration, 10 cm of small bowel was removed due to firm adhesion to the previous surgical scar. Permacol mesh was applied and fixed with transfascial fixations and tacks by using the intraperitoneal onlay mesh technique. There were no complications after the surgery and the patient was discharged without any problems.

AbstractAbstract PDF
PURPOSE
A classic approach to abdominal stab wounds has been a routine laparotomy for the purpose of diagnosis or treatment. However, management protocols for abdominal stab wounds are still contentious in most trauma centers. We examined the relationship between the character of the stab wound and the injured intraabdominal organs by retrospectively analyzing the medical records of patients with abdominal stab wounds admitted to Gil hospital, and the findings for our patients are then confronted with a review of the literature. We aimed to propose proper management protocols to approach abdominal stab wounds.
METHODS
The medical records of all 80 patients sustaining abdominal stab wounds, admitted at the Department of Surgery, Gil Hospital, Gachon Medical School, from January 2004 to December 2008 were retrospectively reviewed. All the abdominal stab wounds were collated based on the site and the character of the injury, investigations performed on admission, results of investigations, operations performed and findings at the time of the operation.
RESULTS
The most prevalent age group was patients in their forties and the average age of the patients was 41 years for both genders. The stab wounds were most commonly located at the periumbilical area (16.9%), followed by the epigastric area (15.6%), and 18.2% of the patients had multiple wounds. The most commonly eviscerated organ was the omentum (9 out of 16 cases); 61.7% of non-eviscerated patients underwent a therapeutic laparotomy while 81.3% of eviscerated patients underwent a therapeutic laparotomy. The small bowel was the most commonly injured organ (22.7%, 17 out of 75 injuries). The review revealed a relatively common diaphragmatic injury in abdominal stab wound patients (8 cases, 10.5%). The average hospital stay was 11 days.
CONCLUSION
This review revealed commonly eviscerated and injured intraabdominal organs in abdominal stab wound patients and their relationship with a therapeutic laparotomy. Although the management is still controversial, the authors suggest indications for an immediate laparotomy and a protocol for managing abdominal stab wounds. Hemodynamic instability and peritoneal irritation signs are definite indicators for an immediate laparotomy, but the review revealed intraabdominal organ evisceration alone not to be a statistically significant factor. In addition, the authors suggest that abnormal CT findings can be valuable for making a decision on management of hemodynamically stable stab wound patients. Further study may clarify a role for a more selective approach to operative intervention and for a more extensive use of selective observation.

AbstractAbstract PDF
Traumatic abdominal wall hernia after blunt abdominal trauma is rare. The prevalence of traumatic abdominal wall hernia in published series is approximately 1%. Recently, by the use of computed tomography has increased the number of occult traumatic abdominal wall hernias (TAWH). A 47-year-old woman presented to the emergency room soon after a traffic accident. She was fully conscious and complained of diffuse, dull, abdominal pain. She had a seat belt on at the time of the accident. Initial computed tomography showed that the lower left abdominal wall had a defect and that a part of the small bowel had herniated through the defect. During the operation, we made an incision at the defect site and confirmed the defect. The defect size was about 15x5 cm. The muscle layers were repaired in layers with absorbable sutures. Prolen mesh was layed down and fixed on the site of the repaired muscle defect. After 6 months, hernia had not recurred, and no weakness of the repaired abdominal wall layers was identified. The patient`s postoperative body functions were normal.
