Background: The purpose of this study is to assess the roles of pediatric surgeons and adult trauma surgeons in the management of pediatric torso trauma patients in a Level I adult trauma center. Methods: From 2015 to 2019, pediatric torso trauma patients (age < 18 years) were studied. A comparison between patients who did and did not undergo surgery was performed. Older children (age: 10–18 years) were compared with young adults (age: 18–35 years) selected with the same criteria using propensity score matching (PSM) and inverse probability of treatment weighting (IPTW). Results: A total of 226 patients were included in the study. Patients who underwent surgery for torso trauma (N = 61) were significantly older than patients who did not undergo surgery (N = 165) (13.1 vs. 10.4 years, p = 0.019). Both PSM and IPTW showed that the older children and young adult groups had similar proportions of patients requiring surgery (32.6% vs. 32.6%, standard difference (SD) = 0.000), proportions of patients who required torso angioembolization (8.7% vs. 9.8%, SD = 0.072), length of hospital stay (LOS) (8.1 vs. 8.0 days, SD = 0.026), and intensive care unit admission LOS (2.6 vs. 2.7 days, SD = 0.033). However, 7.1% of older children received critical care from pediatric surgeons. Additionally, 31.9% of younger children were cared for by pediatric surgeons/pediatricians. Conclusions: Adult trauma surgeons can feasibly perform surgeries for older children with torso trauma in collaboration with pediatric surgeons who provide critical care. [ABSTRACT FROM AUTHOR]

Background: Laparoscopic cholecystectomy (LC) is a common procedure for cholelithiasis paid by diagnostic-related groups (DRGs) systems. However, acute cholecystitis (AC) patients usually have heterogeneous conditions that compromise the successful implementation of DRGs. We evaluated the quality/efficiency of treating AC patients under the DRG system in Taiwan. Methods: All AC patients who underwent LC between October 2015 and December 2016 were included. Patient demographics, treatment outcomes, and financial results were analyzed. Patients were reimbursed by one of the two DRG schemes based on their comorbidities/complications (CC): DRG-1, LC without CC; and DRG-2, LC with CC. Hospitals were reimbursed the costs incurred if they were below the lower threshold (balanced sector); with the outlier threshold if costs were between the lower and outlier thresholds (profitable sector); and with the outlier threshold plus 80% of the exceeding cost if costs were higher than the outlier threshold (profit-losing sector). Results: Among 246 patients, 114 were paid by DRG-1, and 132 were by DRG-2. In total, 195 of 246 patients underwent LC within 1 day after admission, and patients with mild AC had shorter hospital stays than those with moderate or severe AC. The complication rate was 7.3% with only one mortality. In total, 92.1% of patients in DRG-1 and 90.9% of patients in DRG-2 were profitable. The average margin per patient was 11,032 TWD for DRG-1 and 24,993 TWD for DRG-2. Conclusions: DRGs can be well adopted for acute care surgery, and hospitals can still provide satisfactory services without losing profit. [ABSTRACT FROM AUTHOR]

Introduction: In the evaluation of haemorrhage in trauma patients with pelvic fractures, contrast extravasation (CE) on computed tomography (CT) scan often implies active arterial bleeding. However, the absence of CE on CT scan does not always exclude the need for transcatheter arterial embolisation (TAE) to achieve haemostasis. In the current study, we evaluated the factors associated with the need for TAE in patients without CE on CT scan. These factors may be evaluated as adjuncts to CT scanning in the management of patients with pelvic fractures. Methods: We retrospectively reviewed our trauma registry and medical records of patients with pelvic fractures. When CE was observed, indicating active haemorrhage, the patients underwent TAE to achieve haemostasis. In contrast, patients without CE were held for observation and treatment of their injuries, and if their condition deteriorated after a delayed interval, they were then also referred for TAE if no other focus of haemorrhage was found. Patients without CE on CT scan but with retroperitoneal haemorrhage requiring TAE were investigated. Their demographic characteristics, associated injuries, fracture patterns, and changes in systolic blood pressure were described and analysed. Results: In total, 201 patients with pelvic fracture underwent CT scan examination; 47 (23.4%) had CE by CT scan, whereas the other 154 (76.6%) did not. Of the 154 patients who did not show CE by CT scan, 124 (80.5%) patients never underwent TAE; however, 30 (19.5%) of these patients did eventually undergo TAE. In comparing the patients who underwent TAE to those who did not undergo TAE among patients without CE on CT scan, the systolic blood pressure (SBP) on arrival (median: 100.0 mmHg vs 136.0 mmHg, p<0.01) and the lowest SBP recorded in the ED (median: 68.0 mmHg vs 129.0 mmHg, p<0.01) were significantly lower in the patients who underwent TAE. The ROC curve analysis revealed that the most appropriate cutoff value of decrement of SBP (SBP on arrival minus the lowest SBP in the ED) was 30 mmHg (AUC=0.89). Conclusion: In the management of pelvic fracture patients, greater attention should be directed toward patients with relative hypotension. The higher likelihood of haemodynamic deterioration and the need for TAE for haemorrhage control should remain under consideration in such cases, despite the absence of CE by CT scan.

Background/objective: The present study investigated the impact of splenomegaly on the treatment outcomes of blunt splenic injury patients., Methods: All blunt splenic injury patients were enrolled between 2010 and 2018. The exclusion criteria were age less than 18 years, missing data, and splenectomy performed at another hospital. The patients were divided into two groups based on the presence of splenomegaly, defined as a spleen length over 9.76 cm on axial computed tomography. The primary outcome was the need for hemostatic interventions., Results: A total of 535 patients were included. Patients with splenomegaly had more high-grade splenic injuries (p = 0.007). Hemostatic treatments (p < 0.001) and transarterial embolization (p = 0.003) were more frequently required for patients with splenomegaly. Multivariate analysis showed that male sex (p = 0.023), more packed red blood cell transfusions (p = 0.001), splenomegaly (p = 0.019) and grade 3-5 splenic injury (p < 0.001) were predictors of hemostatic treatment. The failure rate of transarterial embolization was not significantly different between the two groups (p = 0.180). The sensitivity and specificity for splenomegaly in predicting hemostatic procedures were 48.8% and 66.5%, respectively. The positive and negative predictive values were 62.8% and 52.9%, respectively. The overall mortality rate was 3.7%., Conclusion: Splenomegaly is an independent predictor for the requirement of hemostatic treatments in blunt splenic injury patients, especially transarterial embolization. Transarterial embolization is as effective for blunt splenic injury patients with splenomegaly as it is for those with a normal spleen., Competing Interests: Declaration of competing interest The authors declare no conflicts of interest., (Copyright © 2022 Asian Surgical Association and Taiwan Robotic Surgery Association.

Objectives: COVID-19 has changed the epidemiology of trauma. However, Taiwan is a country with a low COVID-19 threat, and people's daily lives have remained mostly unchanged during this period. The purpose of this study is to investigate whether the trend of trauma incidence and the service of trauma care is affected by the relatively minor COVID-19 pandemic in Taiwan., Design: A single-institute, retrograde cohort study., Setting: An observational study based on the trauma registry of Chang Gung Memorial Hospital (CGMH)., Participants: Trauma patients presented to the emergency department of CGMH in the period of 1 January to 30 June 2020 (week 1 to week 26) were designated as the COVID-19 group, with 1980 patients in total. Patients of the same period in 2015-2019 were designated as the pre-COVID-19 group, with 10 334 patients overall., Primary and Secondary Outcome Measures: The primary outcome is the incidence of trauma admission. Differences in trauma mechanism, severity, location and outcome were also compared in both groups., Results: A decrease in trauma incidence during March and April 2020 was noticed. Significant change (p<0.001) in trauma mechanisms was discovered, with decreased burn (5.8% vs 3.6%) and assault (4.8% vs 1.2%), and increased transport accidents (43.2% vs 47.2%) and suicide (0.2% vs 1.0%) in the COVID-19 cohort. A shift in injury locations was also found with a 5% decrement of workplace injuries (19.8% vs 14.8%, p<0.001)., Conclusion: The limited COVID-19 outbreak in Taiwan has led to a decreased incidence of trauma patients, and the reduction is mostly attributed to the decline in workplace injuries., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021.

Objective: A video coaching (VC) system has been developed in surgical education. This study compares the educational effect on technical and nontechnical skills of the VC method for teaching laparoscopic surgery., Design: We conducted a prospectively randomized study of an education program to teach laparoscopic procedures., Setting: The study was performed at the Chang Gung Memorial Hospital, a university hospital in Taiwan., Participants: We enrolled sixteen first- or second-year surgical residents.The participants were randomized into VC and conventional teaching (CT) groups, and their surgical skills were judged by the Global Operation Assessment of Laparoscopic Skills (GOALS) and the Objective Structured Assessment of Technical Skills (OSATS). Nontechnical skills were evaluated by the Non-Technical Skills for Surgeons (NOTSS) assessment and self-efficacy questionnaires (SEQs). After the program, posttraining scores were compared to assess improvements., Results: The 16 enrolled participants finished the entire course and completed all the videos during the study period. Comparing the VC and CT groups, we found that the pretraining GOALS, OSATS, NOTSS and SEQ scores were similar between both groups. However, after training, the OSATS score gain was higher in the VC groupthan in the CT group (9.25 ± 2.05 vs. 6.50 ± 1.51, p=0.009). Regarding nontechnical skills, the NOTSS score improved more in the VC group than in the CT group (5.50 ± 0.93 vs. 4.25 ± 0.89, p=0.015). The SEQ score was also higher in the VC group (32.13 ± 2.10) than in the CT group (29.50 ± 1.77), with a significant difference (p=0.018)., Conclusion: VC can help surgeons build their expertise using a more accessible method. Additionally, VC can shorten the learning curve and improve self-efficacy, thereby contributing to surgeons' education., (Copyright © 2019 Association of Program Directors in Surgery.

​OBJECTIVES: To assess the impact of lower socioeconomic status on the outcome of major torso trauma patients under the single-payer system by the National Health Insurance (NHI) in Taiwan. ​DESIGN: A nationwide, retrospective cohort study. ​SETTING: An observational study from the NHI Research Database (NHIRD), involving all the insurees in the NHI. ​PARTICIPANTS: Patients with major torso trauma (injury severity score ≥16) from 2003 to 2013 in Taiwan were included. International Classification of Disease, Ninth Revision, Clinical Modification codes were used to identify trauma patients. A total of 64 721 patients were initially identified in the NHIRD. After applying the exclusion criteria, 20 009 patients were included in our statistical analysis. ​PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome measure was in-hospital mortality, and we analysed patients with different income levels and geographic regions. Multiple logistic regression was used to control for confounding variables. ​RESULTS: In univariate analysis, geographic disparities and low-income level were both risk factors for in-hospital mortality for patients with major torso trauma (p=0.002 and <0.001, respectively). However, in multivariate analysis, only a low-income level remained an independent risk factor for increased in-hospital mortality (p<0.001). ​CONCLUSION: Even with the NHI, wealth inequity still led to different outcomes for major torso trauma in Taiwan. Health policies must focus on this vulnerable group to eliminate inequality in trauma care., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2019.

Introduction: While transcatheter arterial embolization (TAE) is an effective way to control arterial bleeding associated with pelvic fracture, delayed TAE may increase mortality risk. The purpose of the current study was to determine how time to TAE affects outcomes in patients with pelvic fracture in the emergency department., Methods: From January 2014 to December 2016, the trauma registry and medical records of patients with pelvic fracture who underwent TAE were retrospectively reviewed. The relationship between the time to TAE and patient outcomes was evaluated. The characteristics of surviving and deceased patients were also compared to search for prognostic factors affecting survival., Results: Eighty-four patients were enrolled in the current study. Among patients with pelvic fracture who underwent TAE, the overall mortality rate was 16.7%. There were positive relationships between the time to TAE and the requirement for blood transfusion and between the time to TAE and intensive care unit (ICU) length of stay (LOS). Nonsurviving patients were significantly older (57.4 ± 23.3 vs. 42.7 ± 19.3 years old, p  = 0.014) and had higher injury severity scores (ISSs) (36.4 ± 11.9 vs. 23.9 ± 10.9, p  < 0.001) than were observed in surviving patients. There was no significant difference in the time to TAE between nonsurviving and surviving patients (76.9 ± 47.9 vs. 59.0 ± 29.3 min, p  = 0.068). The multivariate logistic regression analysis showed that ISS and age served as independent risk factors for mortality. Every one unit increase in ISS or age resulted in a 1.154- or 1.140-fold increase in mortality, respectively ( p  = 0.033 and 0.005, respectively). However, the time to TAE serves as an independent factor for ICU LOS ( p  = 0.015)., Conclusion: In pelvic fracture patients who require TAE for hemostasis, longer time to TAE may cause harm. An early hemorrhage control is suggested., Competing Interests: Competing interestsThe authors declare that they have no competing interests.

Purposes: This study aimed to clarify the prognosis of polytrauma patients presenting to the emergency department (ED) with a Glasgow Coma Scale score (GCS) of 3., Methods: A trauma registry system has been established at our institution since 2009. The current study reviewed patients in the registry who presented to the ED with a GCS of 3 from January 2011 to December 2015. Surviving and non-surviving patients were compared to identify the prognostic factors of patient survival. The study also aimed to determine the factors contributing to patients who survived with a GCS > 13 at discharge., Results: During the study period, 145 patients were enrolled in the study, 119 of whom (82.1%) did not survive the traumatic insult. Of the 26 survivors, 13 (9.0%) had a GCS of 14 or 15 at discharge. The multiple logistic regression revealed that a lack of bilateral dilated and fixed pupils (BFDP) (OR 5.967, 95% CI 1.780-19.997, p = 0.004) and a GCS > 3 after resuscitation (OR 6.875, 95% CI 2.135-22.138, p = 0.001) were independent prognostic factors of survival. Based on the multiple logistic regression, an age under 40 years (OR 16.405, 95% CI 1.520-177.066, p = 0.021) and a GCS > 3 after resuscitation (OR 12.100, 95% CI 1.058-138.352, p = 0.045) were independent prognostic factors of a GCS > 13 at discharge., Conclusion: Aggressive resuscitation still provided benefit to polytrauma patients presenting with a GCS of 3, especially those with a rapid response to the resuscitation. Young patients with a deep coma on arrival had a higher probability of functional recovery after resuscitation in the ED.

Background: The long-term renal outcomes of patients who underwent nephrectomy for traumatic renal injury (TRI) have rarely been reported. Therefore, we investigated the impact of nephrectomy for TRI on long-term renal outcomes., Methods and Materials: We extracted data from the National Health Insurance Research Database (NHIRD) of Taiwan from 1999 to 2013 and identified patients with TRI. Adverse kidney outcomes (AKOs), including lifelong dialysis and chronic kidney disease (CKD), were chosen as endpoints of the study., Results: A total of 16,320 eligible patients were identified in the NHIRD. The incidence of lifelong dialysis was 0.6% (99/15,789) for patients without nephrectomy, while the incidence was 1.1% (6/531) for nephrectomized patients. Overall, the incidence of AKOs was 2.1% (11/531) in the group that underwent nephrectomy and 1.1% (166/15,789) in the group without nephrectomy. Before matching, differences in overall AKO incidence between the groups were significant, while propensity score matching eliminated this significance., Conclusions: The results of our study did not indicate that AKOs would occur in patients with TRI who underwent nephrectomy., (Copyright © 2019 IJS Publishing Group Ltd.

Background: Conventionally, pelvic fracture-related acute retroperitoneal hemorrhage (ARH) is life threatening and difficult to control. However, the use of angioembolization to treat fracture-associated ARH improves the hemodynamic stability of patients with pelvic fractures. The role of angioembolization in the management of patients with pelvic fracture-related ARH was examined., Materials and Methods: We retrospectively reviewed a large case series of patients with pelvic fractures between January 2010 and December 2014. Comparisons were made between patients with and without ARH. In addition, the characteristics of mortality were delineated, whereas the causes of death in patients with pelvic fracture were discussed and analyzed., Results: A total of 1070 patient records were reviewed during the 60-month study period, and the overall mortality rate of pelvic fracture was 7.7% (82/1070). However, there were only seven patients who died due to uncontrolled ARH (0.7%). The patients with ARH had more injuries to other organs than did the patients without ARH (head: 79.7% vs. 31.7%, p < 0.001; chest: 50.3% vs. 10.9%, p < 0.001; abdomen: 72.0% vs. 22.7%, p < 0.001; spine: 12.6% vs. 4.4%, p < 0.001; extremities: 69.2% vs. 44.3%, p < 0.001)., Conclusion: The treatment for pelvic fracture patients declared dead upon arrival remains limited. However, pelvic fracture-related ARH could be controlled effectively with angioembolization. In addition to ARH, injuries to other organs may play a key role in the mortality of patients with pelvic fractures., (Copyright © 2018 Elsevier Inc. All rights reserved.)

Background: The long-term treatment trends of splenic injuries can provide guidance when treating trauma patients. The nonoperative management (NOM) of splenic injuries was introduced in early 1989. After decades of development, it has proven to be safe and is now the primary treatment choice worldwide. However, there remains a lack of nationwide registry data to support the feasibility and efficiency of NOM., Methods: We used the Taiwan National Health Insurance Research Database to conduct a whole population-based cohort study. Patients admitted with blunt splenic injuries from 2002 to 2013 were identified. Demographic data, management methods, associated injuries, comorbidities and outcome parameters were collected. Patients were divided into 2 groups by the type of admitting institution: a tertiary center or a non-center hospital. We also used 4 years as an interval to analyze the changes in epidemiological data and treatment trends. Comparisons of the results of NOM and surgical management were also performed., Results: A total of 12,455 patients were admitted with blunt splenic injuries between 2002 and 2013. Among the 11,551 patients treated in a single hospital after admission, patients underwent NOM more frequently at tertiary centers than at non-center hospitals (64.6% vs 50.3%). During the 12-year study period, the NOM rate increased from 56 to 73% in tertiary centers, while in noncenter hospitals, the rate only increased from 43 to 58%. The mortality rate decreased in tertiary centers from 8.9 to 7.2%, with no apparent change in noncenter hospitals. Complications occurred more frequently in the surgical management group., Conclusion: There is a trend toward the use of NOM for blunt splenic injury treatments, and the outcomes from the NOM groups were not inferior to those of the operation group. In addition, tertiary centers performed more NOM than did non-center hospitals and better met the international consensus.

Purpose: The Formosa Fun Coast explosion is an internationally-known event that occurred in Taiwan on June 27th, 2015. The blast involved 495 casualties in total, with 253 patients receiving 2nd degree or deeper burns on greater than 40% of the total body surface area (TBSA). Questions were raised regarding whether these victims were sent to the appropriate hospitals or not. Therefore, we analyzed the effect of the initial admission destination in this study., Material and Methods: We retrospectively reviewed all of the victims from the explosion who were sent to the emergency department of Linkou and Keelung Chang Gung Memorial Hospitals. Patients were divided by direct admission and received via transfer. The basic demographics, the efficacy of the initial resuscitation and the clinical outcomes were analyzed., Results: In total, forty-six patients were included. Thirty-five of them were primarily admitted, and eleven of them were received via transfer. Between the two groups, there was no significant difference in the resuscitation outcome. The ratio of delaying intubation was similar (14.3% vs 27.3%, p=0.322). The rate of delayed-detected ischemic events was significantly increased in the referral group (0% vs 27.3%, p=0.001). However, there was no amputation event in either group. No difference in mortality was observed between groups (5.7% vs 9.1%, p=0.692)., Conclusion: Our preliminary findings suggest that local hospitals are capable of providing high-quality acute care to mass casualty burn victims. Our results suggest that patients with suspected limb ischemia should be rapidly transferred to a regional burn center to ensure optimal care. Systemic pre-planning such as employing telemedicine and personnel collaboration, should be considered by the administration to maximize the function of preliminary hospitals in burn care., (Copyright © 2017 Elsevier Ltd and ISBI.

Background: Feeding jejunostomy is an alternative enteral nutritional supplementation method for patients with functional gastrointestinal tracts. In this study, we introduced the novel, safe technique of single-incision laparoscopic-assisted jejunostomy (SIL-AJ) tube placement., Subjects and Methods: We conducted a prospective record search and a retrospective review of all patients who received surgical jejunostomy tube placement in Chang Gung Memorial Hospital, Linkou, Taiwan, from October 2011 to December 2012. SIL-AJ, multiple-incision laparoscopic jejunostomy (MIL-J), and open jejunostomy (O-J) were performed concurrently. We compared the demographic data, operative time, postoperative pain control, and postoperative complications among these groups., Results: Forty patients who received surgical jejunostomy in this period were enrolled in the study. There were 14 patients with SIL-AJ, 10 with MIL-J, and 16 with O-J. There were no differences in age, sex, American Society of Anesthesiologists status, body mass index, or malignancy distribution among the SIL-AJ, MIL-J, and O-J groups. The total operative times for the SIL-AJ, MIL-J, and O-J procedures were 53.3±11.5, 117.3±45.8, and 52.9±16.1 minutes, respectively; SIL-AJ and O-J had similar operative times, which were significantly shorter than the operative times in the MIL-J group (P<.001). The proportions of patients who began feeding within 24 hours in the SIL-AJ, MIL-J, and O-J groups were 100%, 70%, and 37%, respectively; the SIL-AJ group had a higher feeding rate at 24 hours than the two other groups (P=.001). The SIL-AJ and MIL-J groups had fewer postoperative complications than the O-J group (P=.011)., Conclusions: SIL-AJ is a feasible and safe procedure that can be performed in patients who require alternative enteral feeding. Reduced postoperative pain, acceptable incisions, and quick feeding were observed in patients with SIL-AJ. Transumbilical SIL-AJ uses cost-effective appliances, and it is a relatively simple technique to learn and in which togain proficiency.

There is controversy about the appropriate timing for renal replacement therapy in patients with acute kidney injury (AKI). We are interested in the appropriate timing for initiation of continuous renal replacement therapy in critically ill surgical patients with postoperative acute kidney injury. Seventy-three critically ill surgical patients with postoperative AKI who received continuous renal replacement therapy (CRRT) were enrolled. Indications for CRRT were: 1) AKI with hyperkalemia, 2) metabolic acidosis, 3) pulmonary edema refractory to diuretics, and 4) oliguria with progressive azotemia, especially in unstable hemodynamics. Using RIFLE (Risk, Injury, Failure, Loss, End stage) classification, patients who received CRRT in the "Risk" stage were defined as early group, whereas those in the "Injury/ Failure" stage were labeled as late group. We used continuous veno-venous hemofiltration as CRRT in this series. There were 20 patients in the early group and 53 patients in the late group. The mean ages were 61.5 ± 21.8 years versus 60.8 ± 17.5 years. The mortality rate was 50 per cent versus 84.9 per cent. There were no significant differences in demographic characteristics or type of surgery or physiological scores. Our data show that late initiation of CRRT is associated with a lower survival rate in critically ill surgical patients with postoperative AKI; however, further studies are required.

Aim: To determine the timing of mortality after onset of severe acute pancreatitis (SAP) and the course of the disease in a large series of patients., Methods: From July 1996 to June 2005, all patients diagnosed with acute pancreatitis at Chang Gung Memorial Hospital, Taipei, Taiwan were retrospectively studied. Three thousand two hundred and fifty episodes of acute pancreatitis were recorded in 2248 patients (1431 males and 817 females; median age, 55.6 years; range, 18-97 years). Mortality was divided into two groups: early death (<= 14 d after admission), and late death (> 14 d after admission). The clinical features of patients in these two groups were compared., Results: Although the overall mortality rate of acute pancreatitis was 3.8% (123/3250), mortality rate of SAP was as high as 16.3% (105/643). Of those 105 SAP mortalities, 44 (41.9%) deaths occurred within the first 14 d after admission and 61 (58.1%) occurred after14 d. Incidence of early death did not significantly differ from that of late death. The co-morbidities did not contribute to the timing of death. Early deaths mainly resulted from multiple organ failure. Late deaths were mainly caused by secondary complication of infected necrosis. Intra-abdominal bleeding significantly caused higher mortality in late death., Conclusion: Approximately half (42%) of SAP deaths occur within 14 d and most were due to multiple organ failure. The late deaths of SAP were mostly due to infected necrosis.
