RESUMEN
BACKGROUND: Acute cholecystitis (AC) is a common surgical emergency. The Tokyo Guidelines 2018 (TG18) provides a reliable algorithm for the treatment of AC patients to achieve optimal outcomes. However, the economic benefits have not been validated. We hypothesize that good outcomes and cost savings can both be achieved if patients are treated according to the TG18. METHOD: This retrospective study included 275 patients who underwent cholecystectomy in a 15-month span. Patients were divided into three groups (group 1: mild AC; group 2: moderate AC with American Society of Anesthesiologists (ASA) physical status class ≤ 2 and Charlson Comorbidity Index (CCI) score ≤ 5; and group 3: moderate AC with ASA class ≥ 3, CCI score ≥ 6, or severe AC). Each group was further divided into two subgroups according to management (followed or deviated from the TG18). Patient demographics, clinical outcomes, and hospital costs were compared. RESULTS: For group 1 patients, 77 (81%) were treated according to the TG18 and had a significantly higher successful laparoscopic cholecystectomy (LC) rate (100%), lower hospital cost ($1896 vs $2388), and shorter hospital stay (2.9 vs 8 days) than those whose treatment deviated from the TG18. For group 2 patients, 50 (67%) were treated according to the TG18 and had a significantly lower hospital cost ($1926 vs $2856), shorter hospital stay (3.9 vs 9.9 days), and lower complication rate (0% vs 12.5%). For group 3 patients, 62 (58%) were treated according to the TG18 and had a significantly lower intensive care unit (ICU) admission rate (9.7% vs 25%), but a longer hospital stay (12.6 vs 7.8 days). However, their hospital costs were similar. Early LC in group 3 patients did not have economic benefits over gallbladder drainage and delayed LC. CONCLUSION: The TG18 are the state-of-the-art guidelines for the treatment of AC, achieving both satisfactory outcomes and cost-effectiveness.

BACKGROUND: Early diagnosis of blunt cerebrovascular injury (BCVI) is among the most difficult challenges in trauma treatment. This study aimed to determine the optimal timing of computed tomographic angiography (CTA) screening for suspicious BCVI in patients with polytrauma. METHODS: We reviewed the trauma registry and medical records of patients with head and neck injuries from a Level I trauma center between January 2012 and December 2016. Those receiving CTA within 24 h of presentation at the emergency department were the primary CTA group; those who received CTA after 24 h were the delayed CTA group. The basic demographics, indications for CTA, CTA severity grading, and outcomes were compared. RESULTS: In all, 228 patients received brain CTA. Most were male (75%); the mean age was around 40 years. The 38 patients with positive BCVI had a significantly higher ratio of severe chest trauma (52.6% vs 25.8%, p = 0.001); 26 of them received primary CTA and 12 received delayed CTA. Patients with polytrauma predominated in the delayed CTA group (66.7% vs 30.8%, p = 0.037). Of the patients in the primary CTA group, 26.9% received CTA due to symptomatic presentation (p = 0.047). Patients in the delayed group had better neurological outcomes (83% neurologically intact, vs 38.5%, p = 0.01) and lower mortality (0% vs 26.9%, p = 0.047). The only independent positive prognostic factor was initial motor response ≥M5 (Odds Ratio 21.46, 95% Confidence Interval 2.01-228.71). CONCLUSIONS: For patients with polytrauma, performing brain CTA for BCVI screening in the first 24-h or after may not affect clinical outcome. Initial motor response is the sole indicator for outcome. Delaying the study for to the next 24-hour can be considered in such patients, when regarding hemodynamic stability, the dose of contrast medium, and the radiation exposure.

BACKGROUND: Modulated electro-hyperthermia (mEHT) is a form of hyperthermia used in cancer treatment. mEHT has demonstrated the ability to activate host immunity by inducing the release of heat shock proteins, triggering apoptosis, and destroying the integrity of cell membranes to enhance cellular uptake of chemo-drugs in tumor cells. Both curcumin and resveratrol are phytochemicals that function as effective antioxidants, immune activators, and potential inhibitors of tumor development. However, poor bioavailability is a major obstacle for use in clinical cancer treatment. METHODS: This purpose of this study was to investigate whether mEHT can increase anti-cancer efficacy of nanosized curcumin and resveratrol in in vitro and in vivo models. The in vitro study included cell proliferation assay, cell cycle, and apoptosis analysis. Serum concentration was analyzed for the absorption of curcumin and resveratrol in SD rat model. The in vivo CT26/BALB/c animal tumor model was used for validating the safety, tumor growth curve, and immune cell infiltration within tumor tissues after combined mEHT/curcumin/resveratrol treatment. RESULTS: The results indicate co-treatment of mEHT with nano-curcumin and resveratrol significantly induced cell cycle arrest and apoptosis of CT26 cells. The serum concentrations of curcumin and resveratrol were significantly elevated when mEHT was applied. The combination also inhibited the growth of CT26 colon cancer by inducing apoptosis and HSP70 expression of tumor cells while recruiting CD3+ T-cells and F4/80+ macrophages. CONCLUSIONS: The results of this study have suggested that this natural, non-toxic compound can be an effective anti-tumor strategy for clinical cancer therapy. mEHT can enable cellular uptake of potential anti-tumor materials and create a favorable tumor microenvironment for an immunological chain reaction that improves the success of combined treatments of curcumin and resveratrol.

BACKGROUND: Gastrinomas are one of the neuroendocrine tumors with potential distant metastasis. Most gastrinomas are originated from pancreas and duodenum, but those of gastric origin have been much less reported. The aim of the study is to compare gastrinomas of gastric and non-gastric origins. METHODS: Four hundred twenty-four patients with neuroendocrine tumor by histological proof in Chang Gung Memorial Hospital, Linkou branch in the past 10 years were included. A total of 109 (25.7 %) cases were identified of upper gastrointestinal origins, of which 20 (18.3 %) were proven gastrinomas. The clinical characteristics were collected and analyzed retrospectively. RESULTS: In our study, 21 tumors of the 20 cases were identified by pathologic proof, 11 (55 %) had resection or endoscopic mucosa resection, 9 of gastric origins, 9 of duodenal origins, 2 of pancreatic origins, and 1 of hepatic origins. One case had multiple lesions. Patients with gastric gastrinomas had older age, higher levels of gastrin, seemingly smaller tumor size (p = 0.024, 0.030, and 0.065, respectively), and usually lower grade in differentiation (p = 0.035). Though gastric gastrinomas had a high recurrent rate (80 %), the lymph node and liver involvement was less common. Gastrinomas with liver involvement/metastasis had a high mortality rate where 80 % died of liver dysfunction. CONCLUSIONS: Gastrinomas originating from stomach had higher gastrin level and lower tumor grading and presented at older age. The long-term outcome was probably better than non-gastric origin because of lower grading and less lymph node and liver involvement.

BACKGROUND: Hepatic metastasectomy for patients with primary colorectal cancer offers better long-term outcome, and chemotherapy can increase the rate of hepatic resectability for patients with initially inoperable disease. The pattern of liver metastasis and status of the primary tumor are rarely discussed in the analysis of long-term outcome. In this report, we evaluate the influence of the pattern of metastasis on clinical features and prognosis. METHODS: One hundred and fifty-nine patients who underwent hepatic metastasectomy with curative intent for liver metastasis of colorectal cancer between October 1991 and December 2006 were enrolled. Patients were grouped according to whether liver metastasis was centrally or peripherally located, based on imaging and operative findings. Patient demographics, characteristics of the primary and metastatic tumors, and surgical outcomes were analyzed for long-term survival. RESULTS: A greater proportion of patients with centrally located metastases were male, as compared with those with peripherally located metastases. Compared with patients with peripherally located metastases, patients with centrally located metastases were more likely to have multiple lesions (P = 0.016), involvement of multiple segments (P = 0.006), large metastases (P < 0.001), and bilobar distribution of metastases (P < 0.001). The estimated 5-year recurrence-free and overall survival rates were 22.4% and 34.2%, respectively. Univariate analysis revealed that centrally located metastasis, primary tumor in the transverse colon, metastasis in regional lymph nodes, initial extrahepatic metastasis, synchronous liver metastasis, multiple lesions, poorly differentiated tumor, and resection margin <10 mm were significant poor prognostic factors for recurrence-free survival and overall survival. Cox regression analysis showed that inadequate resection margin and centrally located liver metastasis were significant predictors of shorter overall survival. CONCLUSIONS: In colorectal cancer, centrally located liver metastasis represents a poor prognostic factor after hepatectomy, and is associated with early recurrence. Neoadjuvant chemotherapy may be used to downstage centrally located liver metastases to improve outcome.

INTRODUCTION: A pelvic x-ray (PXR) can be used as an effective screening tool to evaluate pelvic fractures and stability. However, associated intra-abdominal/retroperitoneal organ injuries and hemorrhage should also be considered and evaluated in patients with major torso injuries. An abdominal/pelvic computed tomographic (CT) scan may provide higher resolution and more information than a PXR. The role of conventional PXRs was delineated in the current study in the context of the development of the CT scan. MATERIALS AND METHODS: We retrospectively reviewed patients with major torso injuries in our institution. The characteristics of the patients who received different diagnostic modalities (PXR only, CT scan only, or both) were investigated and compared. The characteristics of patients who underwent transcatheter arterial embolization (TAE) for the hemostasis of pelvic fracture-related retroperitoneal hemorrhage were also analyzed. RESULT: There were 726 patients enrolled in current stud. Only 72.0% (523/726) of the patients who had major torso injuries were examined using PXRs, and 69.6% (505/726) of the patients underwent an abdominal/pelvic CT scan. For the patients who were examined using PXRs, there was no significant difference in the usage rate of an additional CT scan between the patients with positive (52.7%, 108/205) and negative (61.0%, 194/318) PXR examinations (P = .070). Four patients underwent TAE immediately following PXR examinations only, without a CT scan. These four patients had unstable pelvic fractures on the PXR examination and significantly a lower systolic blood pressure (61.0 ± 13.0 mmHg), a lower revised trauma score (3.560 ± 2.427), a greater requirement for blood transfusions (1750 ± 957.2 ml) than the patients who underwent TAE after a CT scan. CONCLUSION: For the management of patients with major torso injuries, the role of PXR is diminishing due to the development of the CT scan. However, the PXR is still valuable for patients who are in critical condition and have an obviously high probability of retroperitoneal hemorrhaging.

INTRODUCTION: Transcatheter arterial embolization (TAE) is usually necessary in the management of hemodynamically unstable patients with concomitant pelvic fractures. Given the critical conditions of such patients, TAE is at times performed only according to the results of a primary evaluation without computed tomographic (CT) imaging. Therefore, the evaluation of associated intra-abdominal injuries (IAIs) might be insufficient. Clinically, some patients have required post-TAE laparotomy due to further deterioration. In this study, we attempted to determine a feasible protocol for post-TAE observation. MATERIALS AND METHODS: This study focused on patients who received TAE to achieve hemostasis of retroperitoneal hemorrhage and who did not undergo CT imaging due to their unstable hemodynamics. The characteristics of patients with and without associated IAIs requiring post-TAE laparotomy were compared. We also analyzed the effects of the timing of post-TAE CT imaging on patients with IAIs requiring surgery. RESULTS: A total of 41 patients were enrolled in the study. Of these patients, all of whom underwent primary TAE without preprocedure CT imaging; 15 patients (15/41, 36.6%) required post-TAE laparotomy due to further deterioration. Comparisons between the 2 patient groups revealed no significant differences in the rate of endotracheal intubation (80.0% vs 65.4%, P=.480), loss of consciousness (66.7% vs 73.1%, P=.730), or abdominal symptoms (20.0% vs 23.1%, P=1.000). CONCLUSION: In the management of hemodynamically unstable patients with concomitant pelvic fractures, greater attention should be paid to associated IAIs. Early CT imaging is encouraged after the patient's hemodynamic status is stabilized with TAE.

BACKGROUND: We present a series of patients with blunt abdominal trauma who underwent damage control laparotomy (DCL) and introduce a nomogram that we created to predict survival among these patients. METHODS: This was a retrospective study. From January 2002 to June 2012, 91 patients underwent DCL for hemorrhagic shock. We excluded patients with the following characteristics: a penetrating abdominal injury, age younger than 18 or older than 65 years, a severe or life-threatening brain injury (Abbreviated Injury Scale [AIS] ≥ 4), emergency department (ED) arrival more than 6 hours after injury, pregnancy, end-stage renal disease, or cirrhosis. In addition, we excluded patients who underwent DCL after ICU admission or later in the course of hospitalization. RESULTS: The overall mortality rate was 61.5%: 35 patients survived and 56 died. We identified independent survival predictors, which included a preoperative Glasgow Coma Scale (GCS) score < 8 and a base excess (BE) value < -13.9 mEq/L. We created a nomogram for outcome prediction that included four variables: preoperative GCS, initial BE, preoperative diastolic pressure, and preoperative cardiopulmonary cerebral resuscitation (CPCR). CONCLUSIONS: DCL is a life-saving procedure performed in critical patients, and devastating clinical outcomes can be expected under such dire circumstances as blunt abdominal trauma with exsanguination. The nomogram presented here may provide ED physicians and trauma surgeons with a tool for early stratification and risk evaluation in critical, exsanguinating patients.

BACKGROUND: Due to the presence of other comorbidities and multi-therapeutic modalities in breast cancer, renally cleared chemotherapeutic regimens may cause nephrotoxicity. The aim of this retrospective study is to compare the chemotherapy types and outcomes in breast cancer patients with or without chronic renal disease. PATIENTS AND METHODS: We retrospectively enrolled 62 female patients with breast cancer and underlying late stages (stage 3b, 4, and 5) of chronic kidney disease (CKD) treated from 2000 to 2017. They were propensity score-matched 1:1 with patients in our database with breast cancer and normal renal function (total n = 124). RESULTS: The main subtype of breast cancer was luminal A and relatively few patients with renal impairment received chemotherapy and anti-Her-2 treatment. The breast cancer patients with late-stage CKD had a slightly higher recurrent rate, especially at the locally advanced stage. The 5-year overall survival was 90.1 and 71.2% for patients without and with late-stage CKD, but the breast cancer-related mortality rate was 88.9 and 24.1%, respectively. In multivariate analyses, dose-reduced chemotherapy was an independent negative predictor of 5-year recurrence-free survival and late-stage CKD was associated with lower 5-year overall survival rate. CONCLUSIONS: Breast cancer patients with late-stage CKD may receive insufficient therapeutic modalities. Although the recurrence-free survival rate did not differ significantly by the status of CKD, patients with breast cancer and late-stage CKD had shorter overall survival time but a lower breast cancer-related mortality rate, indicated that the mortality was related to underlying disease.

INTRODUCTION: Transarterial embolization (TAE) or nephrectomy for patients with blunt renal trauma might result in acute kidney injury (AKI). Thus, we analyzed the American College of Surgeons - Trauma Quality Improvement Program (TQIP) to validate this. We hypothesized that nephrectomy, and not TAE, would be a risk factor for AKI in patients with blunt renal trauma. MATERIAL AND METHODS: Adult patients with blunt injuries from the TQIP between 2017 and 2019 were eligible for inclusion. The patients were divided into three treatment groups: conservative treatment, TAE, and nephrectomy. Multivariable logistic regression was used to clarify the AKI predictors. RESULTS: The study included 12,843 patients, wherein 12,373 (96.3 %), 229 (1.8 %), and 241 (1.9 %) patients were in the conservative, TAE, and nephrectomy groups, respectively. A total of 269 (2.2 %), 20 (8.7 %), and 29 (12.0 %) patients had AKI in the three groups, respectively. Both TAE (odds ratio [OR], 2.367; 95 % confidence interval [CI], 1.372-3.900; p = 0.001) and Nephrectomy (OR, 2.745; 95 % CI, 1.629-4.528; p < 0.001) were a statistically significant predictor for AKI in the multivariable logistic regression. CONCLUSIONS: TAE and nephrectomy were statistically associated with AKI in patients with blunt renal trauma. This result differs from our previous research findings that nephrectomy, but not TAE, was a risk factor for AKI in patients with blunt renal trauma. Further prospective and well-designed research may be needed.

INTRODUCTION: Patients with pelvic fracture usually require transfers to trauma centers for additional advanced treatment. Patient safety during the transfer should always be a priority. The noninvasive pelvic circumferential compression device (PCCD) can reportedly provide a tamponade effect, which reduces hemorrhage. In the present study, we evaluated the feasibility and efficiency of PCCD in patients with pelvic fracture who required transfer to trauma centers. MATERIALS AND METHODS: In the present study, we aimed to evaluate patients with pelvic fractures who were transferred from other hospitals. We investigated and compared the characteristics of these types of patients with and without pretransfer PCCD. We compared 2 groups (with and without pretransfer PCCD) of patients under different situations (unstable pelvic fracture, stable pelvic fracture, or indicated for transcatheter arterial embolization). We also analyzed the characteristics of patients with unstable pelvic fracture who were initially evaluated as having stable pelvic fracture primarily before being transferred. RESULTS: During the 53-month period, we enrolled 585 patients in the study. The patients with unstable pelvic fractures who received pretransfer PCCDs required significantly fewer blood transfusions (398.4 ± 417.6 mL vs 1954.5 ± 249.0 mL, P < .001), shorter intensive care unit length of stay (LOS; 6.6 ± 5.2 days vs 11.8 ± 7.7 days, P = .024), and shorter hospital LOS (9.4 ± 7.0 days vs 19.5 ± 13.7 days, P = .006) compared with patients who did not receive the pretransfer PCCD. The stable patients who received pretransfer PCCDs required significantly fewer blood transfusions (120.2 ± 178.5 mL vs 231.8 ± 206.2 mL, P = .018) and had shorter intensive care unit LOS (1.7 ± 3.3 days vs 3.4 ± 2.9 days, P = .029) and shorter hospital LOS (6.8 ± 5.1 days vs 10.4 ± 7.6 days, P = .018) compared with patients who did not receive the pretransfer PCCD. CONCLUSION: Pelvic circumferential compression devices benefit patients with pelvic fracture who need to be transferred to trauma centers. Pretransfer PCCDs appeared to be a feasible and safe procedure during the transfer. In discussions between the referring physicians and the receiving physicians, we recommend using pretransfer PCCDs.

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.

PURPOSE: Delayed diagnosis of blunt traumatic diaphragmatic rupture (BDR) is not uncommon in the emergency department (ED) despite improvement in investigative techniques. We reviewed a large case series of patients diagnosed with blunt traumatic diaphragmatic rupture in order to report demographics, clinical features, and mechanisms of injury of this important but challenging entity. METHODS: From January 2001 through December 2009, 43 patients were diagnosed with BDR at Linkou Chang Gung Memorial Hospital. Demographic data, including sex, age, initial hemodynamic parameters, laboratory data, diagnostic imaging, trauma mechanism, injury location, associated injuries, injury severity score (ISS), time to diagnosis, intensive care unit length of stay (ICU LOS), hospital length of stay (hospital LOS), and mortality, were extracted from hospital records. RESULTS: A total of 43 patients (34 men; 9 women) with BDR were analyzed. Their median age was 37 years (15-82 yrs). Most of these injuries were related to traffic collision (76.8%). The anatomic location of injury to the diaphragm consisted of 24 left-sided (55.8%), 14 right-sided (32.6%),and 5 bilateral diaphragmatic injuries. (11.6%) Hemopneumothorax was the most common associated injury (37.2%). The median diagnostic time was 8 hours (range 2 to 366 hrs). The median ISS score was 18 (range 9 to 41). The median ICU LOS was 4 days (range 0 to 99 ds) and the median HLOS was 19 days (range 1 to 106ds). The total mortality rate was 9.3%. Initial high ISS, initial shock and bilateral diaphragmatic injury significantly increased mortality. CONCLUSION: BDR constitutes a rare entity in thoracoabdominal trauma and most of these injuries were related to traffic collision. High index of suspicion was still the main factor to early diagnosis of this case. The mortality was related to initial shock , bilateral BDR and high ISS. Proper initial resuscitation and correction of other serious injuries may be more life-saving in patients with BDR.

BACKGROUND: Computed tomography (CT) has been used in diagnosing acute appendicitis since late 1990s. Appropriate use of CT has not been studied prospectively in patients with suspected acute appendicitis and relative low Alvarado score. METHODS: Sixty participants with suspected acute appendicitis and an Alvarado score of 4 to 7 points were enrolled for analysis. Clinical and laboratory differences were compared between patients with histologically proven acute appendicitis (AA group) and patients without evidence of acute appendicitis (non-AA group) in the first part of the analysis. In the second part of the analysis, participants were divided into 2 groups: leukocytosis (LK group) and nonleukocytosis (non-LK group). RESULTS: In the first phase of the analysis, there were statistically significant differences in white blood cell count (13.5 K vs 10.9 K per µL), neutrophilia (81.5% vs 73.5%), and hospital stay (4.9 vs 3.5 days) between the 2 groups. Disease spectrum between LK and non-LK groups was obtained in second part of analysis. CONCLUSION: Computed tomography scan is necessary for patients with relatively low Alvarado score when leukocytosis is noted. In female patients without leukocytosis, further large-scale prospective studies are necessary to change the current diagnostic strategy.

BACKGROUND: An accident event may necessitate triage of multiple cases of traumatic out-of-hospital cardiac arrest (TOHCA). However, factors for prioritizing treatment among multiple TOHCA patients have not been established. This study aims to use easily assessible predictors of TOHCA outcomes to develop a triage scoring system. METHODS: Patients with TOHCA brought to our hospital by emergency medical services (EMS) were included for analysis to identify independent risk factors for poor outcomes. A scoring system was developed and validated internally and externally. RESULTS: Of the 401 included patients, 86 (21.4%) had return of spontaneous circulation (ROSC) after cardiopulmonary resuscitation (CPR) for 30 min (81 patients, 94.2%) or 45 min (86 patients, 100%). The emergency department (ED) mortality rate was 89.3% and overall in-hospital mortality rate was 99%. Univariate and multivariate analyses identified body temperature <33 °C (OR, 4.65; 95% CI, 1.37-15.86), obvious chest injury (OR, 2.11; 95% CI, 1.03-4.34), and presumable etiology of out-of-hospital cardiac arrest (OR, 1.73; 95% CI, 1.01-2.98) as significant independent risk factors for non-ROSC. The TOHCA score, calculated as 1 point per risk factor, correlated significantly with the rate of non-ROSC and ED mortality (TOHCA score 0, 1, 2, 3: non-ROSC rate, 63.0%, 80.4%, 90.8%, 100%, respectively; ED mortality rate, 79.5%, 91.5%, 96.1%, and 100% respectively). The results of internal and external validations show a similar trend in both non-ROSC and mortality in the ED with increasing score. CONCLUSIONS: Termination of CPR for TOHCA after 45 min is reasonable; a 30-min resuscitation is acceptable in case of insufficient medical staff or resources. The TOHCA score may be able to be used with caution for triage.

OBJECTIVES: The clinical significance of the highest drain fluid amylase (DFA) level beyond pancreaticoduodenectomy (PD) postoperative day three (POD 3) remains unclear. This study investigated the impact of highest DFA level beyond POD 3 on postoperative pancreatic fistula (POPF) severity and outcomes of patients undergoing PD with POPF. METHODS: Patient demographics of biochemical POPF and clinically relevant POPF (CR-POPF) were compared. Predictive factors were assessed using binary logistic regression. Receiver operating characteristic curve analysis was performed to determine the optimal cutoff value of highest DFA (beyond POD 3). We compared length of hospital stay, surgical mortality rates, and need for postoperative interventions by highest DFA level. RESULTS: Patients with CR-POPF had an older age (p = 0.039), required intraoperative blood transfusion (p = 0.006), and had greater highest DFA levels (p = 0.001) than those with biochemical POPF. The optimal highest DFA cutoff was 2014.5 U/L. Multivariate analysis showed that percentage of patients with intraoperative blood transfusion (p = 0.011; odds ratio, 3.716) and a highest DFA > 2014.5 U/L beyond POD 3 (p = 0.001; odds ratio, 5.722) was predictive of CR-POPF. CONCLUSION: Highest DFA > 2014.5 U/L beyond POD 3 is an independent predictor for CR-POPF. At a highest DFA >2014.5 U/L, 30-day surgical mortality rate, length of stay, and need for postoperative interventions did not differ.

BACKGROUND: Surgery is usually suggested to treat massive haemothorax (MHT). The MHT criteria are based on penetrating trauma observations in military scenarios; the need for surgery in blunt trauma patients remains questionable. This study aimed to determine the characteristics of blunt trauma patients with MHT who required surgery. METHODS: Patients who presented to the emergency department (ED) with traumatic haemothorax or pneumothorax, heart and lung injuries, and thoracic blood vessel injuries from Jan 1, 2014, to Dec 31, 2018, were reviewed. The inclusion criterion was a chest tube drainage amount that met the MHT criteria. Therapeutic operations were defined as those involving surgical haemostasis; otherwise, operations were considered non-therapeutic. The non-therapeutic operation group included the patients who received nonoperative management. The characteristics of the therapeutic and non-therapeutic operation groups were compared. RESULTS: Forty-four patients were enroled in the study. Six patients received conservative treatment and were discharged uneventfully. Eleven patients underwent non-therapeutic operations. The patients with surgical bleeding had a high pulse rate (125.0 (111.0, 135.0) vs. 116.0 (84.0, 121.0) bpm, p = 0.013); low systolic blood pressure (SBP) after resuscitation (106.0 (84.0, 127.0) vs. 121.0 (116.0, 134.0) mmHg, p = 0.040); low pH (7.2 (7.2, 7.3) vs. 7.4 (7.3, 7.4), p = 0.002); and low bicarbonate (17.8 (14.6, 21.5) vs. 21.4 (17.0, 21.5) mEq/L, p = 0.038), low base excess (-9.1 (-13.4, -4.5) vs. -3.8 (-10.1, -0.7), p = 0.028), and high lactate (5.7 (3.3, 7.8) vs. 1.8 (1.7, 2.8) mmol/L, p = 0.002) levels. CONCLUSION: Conservative treatment could be performed selectively in patients with MHT. Lactate could be a predictor of the need for surgical intervention in blunt trauma patients with MHT.

PURPOSE: Traumatic subclavian vascular injury (TSVI) is rare but often fatal. The precise diagnosis of TSVI remains challenging mainly because of its occult nature, less typical presentations, and being overlooked in the presence of polytrauma. Compared to penetrating injuries, it is even more difficult to identify TSVI in patients who have blunt injuries and no visible bleeding. The risk factors associated with TSVI in patients with thoracic trauma are unclear. The aims of this study were to identify risk factors for TSVI in a cohort of patients with thoracic vascular injuries and to report outcomes after clinical treatment. METHODS: From January 2009 to June 2017, 39586 patients were admitted to our hospital (a level I trauma center) due to trauma, and 136 patients with thoracic vascular injury were enrolled in this study. We retrospectively reviewed data from medical records including demographic characteristics, injury scoring systems (RTS, ISS, NISS, TRISS and AIS), management and outcomes. Patients were further divided into the TSVI group (patients with TSVI) and the non-TSVI group (patients with thoracic vascular injuries other than TSVI). Univariate and multivariate analyses were used to identify independent risk factors. RESULTS: The enrolled 136 patients suffered mostly from blunt trauma (89.0%) and 22 of them had TSVI. When compared to the non-TSVI group, the TSVI group had lower Glasgow Coma Scale (GCS) scores (p = 0.002; especially GCS ≤ 12), less concurrent abdominal injury (p < 0.001), lower Injury Severity Scales (ISS) (p = 0.007) and New Injury Severity Scales (NISS) (p < 0.002) but had higher Abbreviated Injury Scales (AIS) of the head ≥ 3 (p = 0.009) and rates of clavicular or scapular fractures (p = 0.013). No difference was detected between the two groups with regard to age, gender, trauma mechanism, vital signs on arrival, or rate of facial and extremities injury. In multivariate regression analyses, GCS ≤ 12, AIS of the head ≥ 3 and the presence of clavicular or scapular fractures were independent risk factors for TSVI (p = 0.026, p = 0.043 and p = 0.005, respectively) after adjustment for confounding factors. Open and endovascular repair were two surgical procedures utilized for these TSVI patients with an overall mortality rate of 18.2%. No difference was found between these groups with regard to mortality rate and the length of ICU stay, but the patients in the TSVI group had a shorter length of hospital stay. CONCLUSIONS: Our results suggest that GCS ≤ 12, AIS of the head ≥ 3 and the presence of clavicular or scapular fractures were independent risk factors for TSVI in patients with thoracic vascular injuries. For patients with thoracic trauma, TSVI should be considered for prompt management when patients exhibit concurrent injuries to the head, clavicle or scapula.

Acute severe pancreatitis caused high mortality, and several scoring systems for predicting mortality are available. We evaluated the effectiveness of serial measurement of several scoring systems in patients with acute severe pancreatitis.We retrospectively obtained serial measurements of Ranson, Acute Physiology and Chronic Health Assessment (APACHE) II, and Sequential Organ Failure Assessment (SOFA) scores of 159 patients with acute severe pancreatitis.The overall mortality rate was 20%, and early mortality (in the first 2 weeks) occurred in 10 (7.4%) patients, while late mortality occurred in 17 (12.6%).All scoring systems were reliable for predicting overall and intensive care unit mortality, while the SOFA score on day 7 presented the largest area under the receiver operator characteristic (ROC) curve (0.858, SE 0.055). Changes in scores over time were evaluated for predicting the progression of organ failure, and the change in SOFA score on hospital day 7 or no interval change in SOFA score was associated with higher mortality rates.APACHE II and SOFA scores are both sensitive for predicting mortality in acute pancreatitis. The serial SOFA scores showed reliable for predicting mortality. Hospital day 7 is a reasonable time for SOFA score reassessment to predict late mortality in acute severe pancreatitis.

BACKGROUND: Computed tomography (CT) plays an important role in diagnosing gastrointestinal perforation. This study explored the relationship between CT findings and the locations of perforated peptic ulcers (PPUs), which may help further surgical planning. METHODS: During a 34-month period, 175 patients had CT scans. We categorized those 175 patients into 2 groups: patients with and without a PPU at a difficult ulcer site for a laparoscopic approach. Both clinical data and the CT images were reviewed and analyzed. RESULTS: Based on the univariate analysis results, we conducted multivariate analyses of 3 factors: age, American Society of Anesthesiologists classification of 3 or more, and positive lesser sac image findings. The positive lesser sac findings in CT were the only independent factor that was correlated to the PPU site. CONCLUSIONS: Positive lesser sac CT findings may help to predict PPUs in sites where a laparoscopic approach might be difficult. Our study re-evaluates the additional value of CT scanning in diagnosing PPU, and the results may assist with surgical planning in clinical practice.
