RESUMEN
BACKGROUND: Understanding the changes in characteristics of patients who visited trauma centres during the coronavirus disease 2019 (COVID-19) pandemic is important to facilitate aneffective response. This retrospective study was conducted to analyse differences in the characteristics and outcomes of patients who visited our trauma centre between pre-COVID-19 and COVID-19 eras. METHODS: Medical data of trauma patients enrolled in the Korean trauma database from 1 January 2018 to 31 August 2021 were collected. The number of trauma centre visits, patient characteristics, factors associated with in-hospital intervention, and outcomes werecompared between patients in the two time periods. Propensity score matching was performed to analyse the outcomes in patients with similar characteristics and severitybetween patients in the two time periods. RESULTS: The number of emergency department (ED) trauma service visits reduced in the COVID-19 era. Based on the mean age, the patients were older in the COVID-19 era. Abbreviated injury scale (AIS) 1, AIS3, AIS5, and injury severity score (ISS) were higher in the COVID-19 era. The proportion of motor vehicle collisions decreased, whereas falls increased during the COVID-19 era. Ambulance transportation, admission to the general ward, and time from injury to ED visit significantly increased. Patient outcomes, such as hospital length of stay (LOS), intensive care unit (ICU) LOS, and duration of mechanical ventilation improved, while injury severity worsened during the COVID-19 era. After adjusting for patient characteristics and severity, similar findings were observed. CONCLUSION: The small reduction in the number of trauma patients and visits by patients who hadhigher ISS during the COVID-19 pandemic highlights the importance of maintaining trauma service capacity and capability during the pandemic. A nationwide or nationalmulticentre study will be more meaningful to examine the impact of the COVID-19 outbreak on the changes in trauma patterns, volume, and patient outcomes.

BACKGROUND: Several recent studies have shown that preperitoneal pelvic packing (PPP) effectively produces hemostasis in patients with unstable pelvic fractures. However, few studies have examined the rate of surgical site infections (SSIs) in patients undergoing PPP following an unstable pelvic fracture. The purpose of the present study was to evaluate factors associated with SSI in such patients. METHODS: We retrospectively reviewed the medical charts of 188 patients who developed hemorrhagic shock due to pelvic fracture between April 2012 and May 2021. Forty-four patients were enrolled in this study. RESULTS: SSI occurred in 15 of 44 patients (34.1%). The SSIs occurred more frequently in cases of repacking during the second-look surgery (0 vs. 4 [26.7%], P=0.010) and combined bladder-urethra injury (1 [3.4%] vs. 4 [26.7%], P=0.039). The incidence of SSIs was not significantly different between patients undergoing depacking within or after 48 hours (12 [41.4%] vs. 5 [33.3%], P=0.603). The mean time to diagnosis of SSI was 8.1±3.9 days from PPP. The most isolated organism was Staphylococcus epidermidis. CONCLUSIONS: Repacking and combined bladder-urethra injury are potential risk factors for SSI in patients with unstable pelvic fracture. Close observation is recommended for up to 8 days in patients with these risk factors. Further, 48 hours after PPP, removing the packed gauze on cessation of bleeding and not performing repacking can help prevent SSI. Additional analyses are necessary with a larger number of patients with the potential risk factors identified in this study.
RESUMEN
Background: In patients with severe injury, predicting the injury site without using advanced diagnostic modalities can help formulate a diagnosis and treatment plan based on the suspected injury site. Objectives: This study aimed to determine the correlation between the injury site and trauma mechanism in severely injured patients with blunt trauma. Methods: We retrospectively analyzed the clinical characteristics-including age, sex, date of emergency room (ER) visit, time of injury, trauma mechanism (car accident, motorcycle accident, bicycle accident, pedestrian accident, fall, slipping and rolling down, crush injury, assault, and others), final diagnosis, injury severity score, abbreviated injury scale (AIS) score, and injury site-of 1,245 patients in a tertiary trauma center. Results: There was a strong correlation between certain injury sites and specific trauma mechanisms. In particular, most trauma mechanisms were associated with injury to the head and neck, as well as the chest, with a combined frequency of >40.0%. Moreover, when using one-way analysis of variance and Bonferroni's post hoc tests, there were significant differences in AIS scores 1, 3, 4, and 5 for each trauma mechanism. Conclusion: Generally, when patients with severe injury present to the ER, the injury site can be predicted upon initial assessment based on the trauma mechanism. Based on our study, the injury site predicted by a specific mechanism should be checked repeatedly and additionally through physical examination and imaging tools. This can reduce misdiagnosis and help with accurate diagnosis and treatment.
RESUMEN
PURPOSE: Recently, several studies have demonstrated symptom-based, non-zonal algorithms for approaching penetrating neck injuries. The purpose of this study was to confirm the effectiveness of the "no zone" approach in traumatic neck injuries. METHODS: Medical charts of patients with traumatic neck injuries who presented at the Regional Trauma Center in South Korea between January 2014 and December 2018 were retrospectively reviewed. Negative final neck findings (FNFs) were compared with positive FNFs (which include major vascular, aerodigestive, nerve, endocrine gland, cartilage, or hyoid bone injuries) using multivariate logistic regression analysis including values of the "zone" and/or no zone approach. RESULTS: Out of 168 trauma patients, 70 patients with a minor injury and 7 patients under the age of 18 years were excluded. Of the remaining 91 patients, 74 (81.3%) had penetrating neck injuries and 17 (18.7%) had blunt neck injuries. Initial diagnosis most frequently revealed external wounds in zone II (84.6%). Twenty (22.0%) and 36 (39.5%) patients had hard and soft signs, respectively, using the no zone approach. Further, there was a significant difference between the negative and positive FNFs in patients with hard signs (11.6% vs. 54.5%; P < 0.01, respectively). According to the multivariate logistic regression analysis, the hard signs were associated with an odds ratio (OR) for FNFs (OR, 18.92; 95% confidence interval, 3.55-157.60). CONCLUSION: Traumatic neck injuries classified as having hard signs based on the no zone approach may be correlated with internal organ injuries of the neck.
RESUMEN
Although the da Vinci Single-Site® silicone port allows exact alignment and effective triangulation of instruments, it also has drawbacks. We introduce an alternative docking technique using the Glove port®. From April 2014 to December 2016, respective 50 patients of the conventional silicone port and the glove port group were compared. The mean docking time was 16.6 ± 6.6 min in the silicone port group and 10.6 ± 3.6 min in the glove port group. Re-docking during the operation was needed in three patients in the silicone port group and readjustment of cannulae without re-docking could be simply performed in five patients in the glove port group. Skin injury was observed in 17 patients in the silicone port group and 0 patients in the glove port group without significant complications. Some limitations of the conventional silicone port were improved by the glove port.

BACKGROUND: Complete removal of the dilated biliary tree is regarded as inevitable in choledochal cysts due to its malignant potential. However, technical difficulty and the high risk of postoperative complications as well as the various presentations of the disease make the surgical options for type IV-A cysts challenging and controversial. We report the first case of a type IV-A choledochal cyst treated using a robot-assisted approach. PATIENT AND METHODS: A 41-year-old healthy female was admitted with intrahepatic and extrahepatic cysts incidentally found on routine checkup. Preoperative image studies showed two large cystic dilatations of the main biliary tract at the hilum and distal common bile duct as well as multiple cystic dilatations of the left intrahepatic duct. Anomalous pancreatico-biliary duct union was also found. The mid common bile duct was transected first, and the distal cystic bile duct of the intrapancreatic portion was resected at the junction with the pancreatic duct. The hilar cyst involved the right intrahepatic portion; therefore, liver resection proceeded to the right lobe, removing the caudate lobe. The right anterior and posterior hepatic ducts were securely isolated and resected with the help of real-time fluorescent imaging using an ICG. Roux-en-Y hepaticojejunostomy was performed intracorporeally. RESULT: The total operation time was 540 min. The estimated amount of intraoperative bleeding was 750 ml. No blood transfusion was given. CT on postoperative day 6 showed no complications. Pathologic examination was accorded in choledochal cysts without evidence of malignancy. The patient was discharged on postoperative day 7 in good condition. CONCLUSION: Hepatectomy and complete excision of the extrahepatic bile duct for type IV-A choledochal cysts requires fine and delicate surgical techniques. The wrist-like movement of the working instruments and the firefly imaging of the robot surgical system allowed this advanced minimally invasive surgery to be successfully performed on this patient.
