Severe TBI is estimated at 73 cases per 100,000 people. The mortality of severe TBI can be reduced if a timely diagnosis and treatment of the injuries are made through prognostic factors. Objective: To determine the prognostic factors related to mortality in severe traumatic brain injury at the Hospital General de Zona No. 46. Material and Methods: Retrospective, cross-sectional and descriptive study in beneficiaries admitted to the Hospital General de Zona (HGZ) No. 46 of the Mexican Institute of Social Security (IMSS by its acronym in Spanish), with a diagnosis of severe TBI;the possible prognostic factors related to mortality of severe TBI were obtained from their records. Measures of central tendency and chi square were used for data analysis. Results: The study sample consisted of 60 subjects diagnosed with severe traumatic brain injury, of which 5 (8%) were women and 55 (92%) were men, and all 60 (100%) patients died. The average age of the sample was 26 with a standard deviation of 9 years. The variables that had a p value less than or equal to 0.05 were: Mydriasis, seizures, Hyperglycemia, Normoglycemia, Hypothermia and Hypotension. This means that these variables were associated with mortality. Conclusion: Statistical significance is demonstrated in prognostic factors of mortality in severe traumatic brain injury with p < 0.05 in the case of mydriasis, seizures, hyperglycemia, normoglycemia, hypothermia and hypotension.展开更多

Patient and Method: It is a retrospective analytical study, carried out at the Armentieres Hospital Centre (France) over a period of 14 months. It analyzes computed tomography reports and emergency department results of severe trauma patients immediately stabled at the entrance or stabilized after benefiting from a full body scanner according to Vittel criteria. Results: One hundred eighty patients were included in the study with an average age of 32.71 years old. One hundred and twelve patients (62.2%) had at least one clinical sign and only 48 patients presented a lesion on the computed tomography (26.7%). Sixty-two patients (34.4%) showed neither clinical signs nor damage in scan. The radio-clinical correlation was bad at spinal and abdominal level, mediocre at brain and chest level, but it was medium in the pelvis. The average radiation dose per patient was 3319.21 mGy⋅cm. Conclusion: The whole body computed tomography or scanning allows fast images acquisition compatible with emergency situation and with a satisfactory diagnostic reliability, but still remains an irradiating exam. The results of this study lead to reflect on the use of Vittel criteria that could be improved to reduce the number of normal tests carried out.展开更多

This retrospective study recruited 10 patients of 10 eyes. With our surgical intervention, all the 10 eyes achieved retinal and ciliary body anatomic re-attachment. The choroidal ruptures in nine eyes were closed with complete choroidal reattachment. Postoperative best-corrected visual acuity of nine eyes had various improvements. The mean intraocular pressure was increased from 8.9±2.6 mm Hg to 13.4±4.4 mm Hg. Eventually, six eyes underwent silicone oil(SO) removal without complications, two eyes still had SO tamponade and two eyes became SO-dependent eyes. The result shows that internal direct cyclopexy combined with scleral buckling is an effective treatment for severe traumatic cyclodialysis cleft in OGIS.展开更多

Aging results in a progressive decline in cellular function which leads to a loose of their capacity to respond to injury. Some medications commonly used in this population can mask or blunt the response to injury. Falls constitute the most common cause of trauma and the leading cause of trauma-related deaths in this population. Falls are complicated by the widespread use of antiplatelets and anticoagulants, especially in patients with brain injury. Under-triage is common in this population. Evaluation of frailty could be helpful to solve this issue. Appropriate triaging and early aggressive management with correction of coagulopathy can improve outcome. Limitation of care and palliative measures must be considered in cases with a clear likelihood of poor prognosis.展开更多

Sixty-four cases of severe trauma (injury severity score ≥20) with stress hyperglycemia (blood glucose >9 mmol/L) were randomly divided into intensive insulin therapy group and conventional therapy group. ELISA method, radioimmunoassay and density gradient grada- tion one-step process were used to determine plasma VEGF, endothelin-1 (ET-1), and the number of circulating endothelial cells (CECs) at the day of 0, 2, 3, 5 and 7 after admission. Simultaneously, the changes of CRP concentration in plasma were monitored to evaluate inflammatory response. The results showed that plasma levels of observational indexes in patients receiving early-stage intensive insulin therapy were all significantly lower than those in conventional therapy groups 2, 3, 5 and 7 days after admission [for VEGF (ng/L), 122.2±23.8vs. 135.9±26.5, 109.6±27.3vs. 129.0±18.4, 88.7±18.2vs. 102.6±27.3, 54.2±26.4vs. 85.7±35.2, P<0.05, 0.01, 0.05, 0.05 respectively; for ET-1 (ng/L), 162.8±23.5 vs. 173.7±13.2, 128.6±17.5 vs. 148.8±22.4, 96.5±14.8 vs. 125.7±14.8, 90.7±16.9vs. 104.9±22.5, P<0.05, 0.01, 0.01, 0.01 respectively; for CRP (mg/L), 23.2±13.8vs. 31.9±16.5, 13.6±17.3 vs. 23.5±18.4, 8.7±10.2vs. 15.6±13.3, 5.2±9.4vs. 10.7±11.2, all P<0.05; for CECs (/0.9 μL), 10.9±5.6vs. 13.9±6.2, 8.5±4.9 vs. 11.3±5.3, 6.3±6.4vs. 9.4±5.7, 4.8±7.1vs. 7.8±4.8, all P<0.05]. It was concluded that intensive insulin therapy could antagonize the endothelium injury after trauma and reduce inflammation response quickly, which was one of important mechanisms by which intensive insulin therapy improves the prognosis of trauma patients.展开更多

All the patients admitted at the surgical intensive care unit for a traumatic brain injury with an initial Glasgow coma scale score ≤ 8 were included. One hundred and thirty-five cases were enrolled. One hundred and fourteen were males and 21 were females. Their mean age was 32.75 years. Forty-four patients were aged between 16 to 30 years. Road traffic accidents represented the first mode of injury with 101 cases and most of the patients were pedestrians hit by a car. Pupils and students were the most involved. Twenty-three patients had additional extracranial injury. On admission, 97 (71.85%) patients had GCS 7-8. A brain CT scan was done for 115 patients. Intracranial and intracerebral hemorrhages were the most frequent radiological findings with 57 cases. The overall mortality was 32.59% with 44 deaths. Thirty-two of the deaths occurred in patients with GCS 7 - 8 on admission. Ninety-one (67.40%) patients survived, 74 (54.81%) had persisting disabilities, while only 17 (12.59%) recovered fully. The following factors had an impact on the outcome: GCS at admission, pupillary anomalies, length of hospital stay, endotracheal intubation and surgery. Severe TBI remains a heavy socio-economic burden worldwide. In Cameroon where the health system is poorly organized, the outcome of individuals who sustained a severe TBI was dismal.展开更多

The subjects included 20 sTBI patients with memory disorder and 22 healthy individuals. Memory function was measured by using WMS-RC. Behavioral and ERP responses were recorded on-line during performance on a battery of picture recognition and the responses were analyzed off-line for recognition memory effects. Mean memory quotient (MQ) of patients with sTBI was significantly lower than that of the control group. Mean reaction time (RT) was significantly longer and the mean correctness rate (CR) of picture recognition was significantly lower in sTBI group than that of the controls. In controls, the main components of average ERP of picture recognition includes two positive-going waves, designated as P170 and P500, that appear 170 ms and 500 ms after stimulation when the subject could later successfully recall and recognize the pictures. P500 amplitude of target stimulus was significantly higher than that of non-target stimulus. Compared to controls, P500 responses of sTBI group were significantly delayed in latency (P<0.001) and lower in amplitude (P<0.001). P500 latency showed significant negative correlation with MQ and the scores of "addition", "visual recognition", "picture recall", "visual reproduction" and "tactile memory" in WMS-RC. ERP of picture recognition provides a neurophysiological approach to directly assess memory impairment, and P500 may serve as a helpful index for memory disorder caused by sTBI in forensic practice.展开更多

Medical charts were retrospectively reviewed with regard to possible trigger mechanisms for cholestasis, and the clinical course was recorded.RESULTS: Diagnosis of secondary sclerosing cholangitis was based in all patients on the primary sclerosing cholangitis (PSC)-like destruction of the intrahepatic bile ducts at cholangiography after exclusion of PSC. In four patients, arterial hypotension with subsequent ischemia may have caused the bile duct damage, whereas in the case of power current injury direct thermal damage was assumed to be the trigger mechanism. The course of secondary liver fibrosis was rapidly progressive and proceeded to liver cirrhosis in all four patients with a follow-up ＞2 years. Therapeutic possibilities were limited.CONCLUSION: Posttraumatic sclerosing cholangitis is a rare but rapidly progressive disease, probably caused by ischemia of the intrahepatic bile ducts via the peribiliary capillary plexus due to arterial hypotension. Gastroenterologists should be aware of this disease in patients with persistent cholestasis after severe trauma.展开更多
文摘Introduction: A traumatic brain injury (TBI) is caused by a forceful bump, blow, or jolt to the head or body, or by an object that pierces the skull and interrupts the normal function of the brain. Severe TBI is estimated at 73 cases per 100,000 people. The mortality of severe TBI can be reduced if a timely diagnosis and treatment of the injuries are made through prognostic factors. Objective: To determine the prognostic factors related to mortality in severe traumatic brain injury at the Hospital General de Zona No. 46. Material and Methods: Retrospective, cross-sectional and descriptive study in beneficiaries admitted to the Hospital General de Zona (HGZ) No. 46 of the Mexican Institute of Social Security (IMSS by its acronym in Spanish), with a diagnosis of severe TBI;the possible prognostic factors related to mortality of severe TBI were obtained from their records. Measures of central tendency and chi square were used for data analysis. Results: The study sample consisted of 60 subjects diagnosed with severe traumatic brain injury, of which 5 (8%) were women and 55 (92%) were men, and all 60 (100%) patients died. The average age of the sample was 26 with a standard deviation of 9 years. The variables that had a p value less than or equal to 0.05 were: Mydriasis, seizures, Hyperglycemia, Normoglycemia, Hypothermia and Hypotension. This means that these variables were associated with mortality. Conclusion: Statistical significance is demonstrated in prognostic factors of mortality in severe traumatic brain injury with p < 0.05 in the case of mydriasis, seizures, hyperglycemia, normoglycemia, hypothermia and hypotension.
文摘BACKGROUND The increase in severe traumatic brain injury(sTBI)incidence is a worldwide phenomenon,resulting in a heavy disease burden in the public health systems,specifically in emerging countries.The shock index(SI)is a physiological parameter that indicates cardiovascular status and has been used as a tool to assess the presence and severity of shock,which is increased in sTBI.Considering the high mortality of sTBI,scrutinizing the predictive potential of SI and its variants is vital.AIM To describe the predictive potential of SI and its variants in sTBI.METHODS This study included 71 patients(61 men and 10 women)divided into two groups:Survival(S;n=49)and Non-survival(NS;n=22).The responses of blood pressure and heart rate(HR)were collected at admission and 48 h after admission.The SI,reverse SI(rSI),rSI multiplied by the Glasgow Coma Score(rSIG),and Age multiplied SI(AgeSI)were calculated.Group comparisons included Shapiro-Wilk tests,and independent samples t-tests.For predictive analysis,logistic regression,receiver operator curves(ROC)curves,and area under the curve(AUC)measurements were performed.RESULTS No significant differences between groups were identified for SI,rSI,or rSIG.The AgeSI was significantly higher in NS patients at 48 h following admission(S:26.32±14.2,and NS:37.27±17.8;P=0.016).Both the logistic regression and the AUC following ROC curve analysis showed that only AgeSI at 48 h was capable of predicting sTBI outcomes.CONCLUSION Although an altered balance between HR and blood pressure can provide insights into the adequacy of oxygen delivery to tissues and the overall cardiac function,only the AgeSI was a viable outcome-predictive tool in sTBI,warranting future research in different cohorts.
文摘Objective:To evaluate the therapeutic effect of enteral nutrition+probiotics in patients with gastrointestinal dysfunction after severe craniocerebral injury.Methods:From September 2018 to February 2023,80 patients(20-82 years old)with gastrointestinal dysfunction who were admitted to the Intensive Care Unit at the Third People’s Hospital of Xining were included in the study.Their primary condition was severe craniocerebral injury,and all of them received conventional symptomatic treatment.Group A received enteral nutrition+probiotic therapy,whereas group B received enteral nutrition only.The differences in the following indicators were compared before and after treatment:nutritional and biochemical indicators,gastrointestinal function indicators,Glasgow Coma Scale(GCS),Sequential Organ Failure Assessment(SOFA),APACHE II score,serum procalcitonin(PCT),neutrophil(N)ratio,and C reactive protein(CRP).Result:The nutritional and biochemical indicators in group A were higher than those in group B,P<0.05;the time to first passage of flatus,time to first passage of stool,and bowel sound recovery time in group A were shorter than those in group B,P<0.05;the GCS of group A was higher than that of group B,P<0.05;the SOFA and APACHEⅡscores of group A were not different from those of group B,P>0.05;and the PCT,N ratio,and CRP levels of group A were lower than those of group B,P<0.05.Conclusion:In patients with gastrointestinal dysfunction after severe craniocerebral injury,enteral nutrition+probiotic therapy is highly effective and feasible,as it can optimize various nutritional indicators,shorten the gastrointestinal function recovery time,and reduce the body’s stress response.

Patient and Method: It is a retrospective analytical study, carried out at the Armentieres Hospital Centre (France) over a period of 14 months. It analyzes computed tomography reports and emergency department results of severe trauma patients immediately stabled at the entrance or stabilized after benefiting from a full body scanner according to Vittel criteria. Results: One hundred eighty patients were included in the study with an average age of 32.71 years old. One hundred and twelve patients (62.2%) had at least one clinical sign and only 48 patients presented a lesion on the computed tomography (26.7%). Sixty-two patients (34.4%) showed neither clinical signs nor damage in scan. The radio-clinical correlation was bad at spinal and abdominal level, mediocre at brain and chest level, but it was medium in the pelvis. The average radiation dose per patient was 3319.21 mGy⋅cm. Conclusion: The whole body computed tomography or scanning allows fast images acquisition compatible with emergency situation and with a satisfactory diagnostic reliability, but still remains an irradiating exam. The results of this study lead to reflect on the use of Vittel criteria that could be improved to reduce the number of normal tests carried out.

文摘This study aimed to evaluate the effect of scleral buckling combined with internal cyclopexy on the treatment of severe traumatic cyclodialysis cleft in open globe injuries(OGIS). This retrospective study recruited 10 patients of 10 eyes. With our surgical intervention, all the 10 eyes achieved retinal and ciliary body anatomic re-attachment. The choroidal ruptures in nine eyes were closed with complete choroidal reattachment. Postoperative best-corrected visual acuity of nine eyes had various improvements. The mean intraocular pressure was increased from 8.9±2.6 mm Hg to 13.4±4.4 mm Hg. Eventually, six eyes underwent silicone oil(SO) removal without complications, two eyes still had SO tamponade and two eyes became SO-dependent eyes. The result shows that internal direct cyclopexy combined with scleral buckling is an effective treatment for severe traumatic cyclodialysis cleft in OGIS.

文摘Geriatric trauma constitutes an increasingly recognized problem. Aging results in a progressive decline in cellular function which leads to a loose of their capacity to respond to injury. Some medications commonly used in this population can mask or blunt the response to injury. Falls constitute the most common cause of trauma and the leading cause of trauma-related deaths in this population. Falls are complicated by the widespread use of antiplatelets and anticoagulants, especially in patients with brain injury. Under-triage is common in this population. Evaluation of frailty could be helpful to solve this issue. Appropriate triaging and early aggressive management with correction of coagulopathy can improve outcome. Limitation of care and palliative measures must be considered in cases with a clear likelihood of poor prognosis.

文摘The influence of early-stage intensive insulin therapy on the plasma levels of vascular endothelial growth factor (VEGF) and the related parameters in patients with severe trauma and the clinical implication were investigated. Sixty-four cases of severe trauma (injury severity score ≥20) with stress hyperglycemia (blood glucose >9 mmol/L) were randomly divided into intensive insulin therapy group and conventional therapy group. ELISA method, radioimmunoassay and density gradient grada- tion one-step process were used to determine plasma VEGF, endothelin-1 (ET-1), and the number of circulating endothelial cells (CECs) at the day of 0, 2, 3, 5 and 7 after admission. Simultaneously, the changes of CRP concentration in plasma were monitored to evaluate inflammatory response. The results showed that plasma levels of observational indexes in patients receiving early-stage intensive insulin therapy were all significantly lower than those in conventional therapy groups 2, 3, 5 and 7 days after admission [for VEGF (ng/L), 122.2±23.8vs. 135.9±26.5, 109.6±27.3vs. 129.0±18.4, 88.7±18.2vs. 102.6±27.3, 54.2±26.4vs. 85.7±35.2, P<0.05, 0.01, 0.05, 0.05 respectively; for ET-1 (ng/L), 162.8±23.5 vs. 173.7±13.2, 128.6±17.5 vs. 148.8±22.4, 96.5±14.8 vs. 125.7±14.8, 90.7±16.9vs. 104.9±22.5, P<0.05, 0.01, 0.01, 0.01 respectively; for CRP (mg/L), 23.2±13.8vs. 31.9±16.5, 13.6±17.3 vs. 23.5±18.4, 8.7±10.2vs. 15.6±13.3, 5.2±9.4vs. 10.7±11.2, all P<0.05; for CECs (/0.9 μL), 10.9±5.6vs. 13.9±6.2, 8.5±4.9 vs. 11.3±5.3, 6.3±6.4vs. 9.4±5.7, 4.8±7.1vs. 7.8±4.8, all P<0.05]. It was concluded that intensive insulin therapy could antagonize the endothelium injury after trauma and reduce inflammation response quickly, which was one of important mechanisms by which intensive insulin therapy improves the prognosis of trauma patients.
文摘To study the effect of mild hypothermia on glucose metabolism and glycerol of brain tissue in patients with severe traumatic brain injury (sTBI).Methods All 33 patients with sTBI(GCS≤8) were randomly divided into hypothermic group and control group.Microdialysis catheters were inserted into the cerebral cortex of perilesion,relative normal brain tissue and subcutaneous tissue of abdomen in order to analyze the concentrations of lactate/pyruvate (L/P),lactate/glucose (L/G) and the glycerol(Gly) in extracellular fluid (ECF).Results In comparison with the control group,the concentration of L/G,L/P and Gly in periphery and that of L/P in ECF of the “normal brain tissue” were significantly decreased in the hypothermic group.In control group,concentration of L/G,L/P and Gly in periphery were higher than those in relative normal brain.In the hypothermic group,L/P concentration in periphery was higher than that in relative normal brain.Conclusion Mild hypothermia protects brain by decreasing concentrations of L/G,L/P and Gly in periphery and L/P concentration in “normal brain tissue”.The energy crisis and membrane phospholipid breakage in periphery are easier to happen after TBI,where mild hypothermia exerts significant protgective role.12 refs,3 tabs.

文摘The rat high-impact free weight drop model mimics the diffuse axonal injury caused by severe traumatic brain injury in humans,while severe controlled cortical impact can produce a severe traumatic brain injury model using precise strike parameters.In this study,we compare the pathological mechanisms and pathological changes between two rat severe brain injury models to identify the similarities and differences.The severe controlled cortical impact model was produced by an electronic controlled cortical impact device,while the severe free weight drop model was produced by dropping a 500 g free weight from a height of 1.8 m through a plastic tube.Body temperature and mortality were recorded,and neurological deficits were assessed with the modified neurological severity score.Brain edema and bloodbrain barrier damage were evaluated by assessing brain water content and Evans blue extravasation.In addition,a cytokine array kit was used to detect inflammatory cytokines.Neuronal apoptosis in the brain and brainstem was quantified by immunofluorescence staining.Both the severe controlled cortical impact and severe free weight drop models exhibited significant neurological impairments and body temperature fluctuations.More severe motor dysfunction was observed in the severe controlled cortical impact model,while more severe cognitive dysfunction was observed in the severe free weight drop model.Brain edema,inflammatory cytokine changes and cortical neuronal apoptosis were more substantial and blood-brain barrier damage was more focal in the severe controlled cortical impact group compared with the severe free weight drop group.The severe free weight drop model presented with more significant apoptosis in the brainstem and diffused blood-brain barrier damage,with higher mortality and lower repeatability compared with the severe controlled cortical impact group.Severe brainstem damage was not found in the severe controlled cortical impact model.These results indicate that the severe controlled cortical impact model is relatively more stable,more reproducible,and shows obvious cerebral pathological changes at an earlier stage.Therefore,the severe controlled cortical impact model is likely more suitable for studies on severe focal traumatic brain injury,while the severe free weight drop model may be more apt for studies on diffuse axonal injury.All experimental procedures were approved by the Ethics Committee of Animal Experiments of Tianjin Medical University,China(approval No.IRB2012-028-02)in Febru ary 2012.
文摘This study was a retrospective analysis of the epidemiologic profile of severe traumatic brain injuries managed at the surgical intensive care unit of the University Hospital Center of Yaoundé, Cameroon, between January 2011 and December 2015. All the patients admitted at the surgical intensive care unit for a traumatic brain injury with an initial Glasgow coma scale score ≤ 8 were included. One hundred and thirty-five cases were enrolled. One hundred and fourteen were males and 21 were females. Their mean age was 32.75 years. Forty-four patients were aged between 16 to 30 years. Road traffic accidents represented the first mode of injury with 101 cases and most of the patients were pedestrians hit by a car. Pupils and students were the most involved. Twenty-three patients had additional extracranial injury. On admission, 97 (71.85%) patients had GCS 7-8. A brain CT scan was done for 115 patients. Intracranial and intracerebral hemorrhages were the most frequent radiological findings with 57 cases. The overall mortality was 32.59% with 44 deaths. Thirty-two of the deaths occurred in patients with GCS 7 - 8 on admission. Ninety-one (67.40%) patients survived, 74 (54.81%) had persisting disabilities, while only 17 (12.59%) recovered fully. The following factors had an impact on the outcome: GCS at admission, pupillary anomalies, length of hospital stay, endotracheal intubation and surgery. Severe TBI remains a heavy socio-economic burden worldwide. In Cameroon where the health system is poorly organized, the outcome of individuals who sustained a severe TBI was dismal.

文摘Objective:To estimate the incidence and related risk factors of sepsis between road traffic injuries (RTIs) and non-RTIs.Methods:Clinical data of 339 patients with severe trauma who were admitted into ICU in both Third Affiliated Hospital of Army Military Medical University and ChongGang General Hospital from January 2012 to December 2015 were retrospectively analyzed.Twenty items of potential risk factors affecting sepsis were evaluated by univariate and multivariate Logistic Analysis with the purpose of drawing a comparison between RTI patients and non-RTI patients.Results:There were 154 cases of RTI and 185 cases of nonRTI entering the study period.The significant independent risk factor of sepsis in RTIs was SOFA 11 (0R=4.821;95% CI=1.901-12.226;P=0.001).The significant independent risk factors of sepsis in non-RTIs were SOFA 11 (OR=12.410;95% CI=2.559-60.185;P=0.002),trachcal intubation (OR=8.913;95% CI=2.322-34.206;P=-0.001),APACHE Ⅱ 15 (0R=3.684;95% CI=1.750-7.753;P=0.001).Conclusions:The clinical medical personnel should not give equal treatment to RTI patients and non-RTI patients admitted in ICU in that factors predicting sepsis within above two groups are different.The sample volume should be increased and validated in further prospective research.
文摘This study explored the possibility of using event-related potentials (ERP) for the measurement of picture-recognition memory and examined its correlation with the Chinese Wechsler Memory Scale-revised (WMS-RC) in patients with memory disorder caused by severe traumatic brain injury (sTBI). The subjects included 20 sTBI patients with memory disorder and 22 healthy individuals. Memory function was measured by using WMS-RC. Behavioral and ERP responses were recorded on-line during performance on a battery of picture recognition and the responses were analyzed off-line for recognition memory effects. Mean memory quotient (MQ) of patients with sTBI was significantly lower than that of the control group. Mean reaction time (RT) was significantly longer and the mean correctness rate (CR) of picture recognition was significantly lower in sTBI group than that of the controls. In controls, the main components of average ERP of picture recognition includes two positive-going waves, designated as P170 and P500, that appear 170 ms and 500 ms after stimulation when the subject could later successfully recall and recognize the pictures. P500 amplitude of target stimulus was significantly higher than that of non-target stimulus. Compared to controls, P500 responses of sTBI group were significantly delayed in latency (P<0.001) and lower in amplitude (P<0.001). P500 latency showed significant negative correlation with MQ and the scores of "addition", "visual recognition", "picture recall", "visual reproduction" and "tactile memory" in WMS-RC. ERP of picture recognition provides a neurophysiological approach to directly assess memory impairment, and P500 may serve as a helpful index for memory disorder caused by sTBI in forensic practice.
文摘AIM: Persistent cholestasis is a rare complication of severe trauma or infections, Little is known about the possible pathomechanisms and the clinical course,METHODS: Secondary sclerosing cholangitis was diagnosed in five patients with persistent jaundice after severe trauma (one burn injury, three accidents, one power current injury). Medical charts were retrospectively reviewed with regard to possible trigger mechanisms for cholestasis, and the clinical course was recorded.RESULTS: Diagnosis of secondary sclerosing cholangitis was based in all patients on the primary sclerosing cholangitis (PSC)-like destruction of the intrahepatic bile ducts at cholangiography after exclusion of PSC. In four patients, arterial hypotension with subsequent ischemia may have caused the bile duct damage, whereas in the case of power current injury direct thermal damage was assumed to be the trigger mechanism. The course of secondary liver fibrosis was rapidly progressive and proceeded to liver cirrhosis in all four patients with a follow-up ＞2 years. Therapeutic possibilities were limited.CONCLUSION: Posttraumatic sclerosing cholangitis is a rare but rapidly progressive disease, probably caused by ischemia of the intrahepatic bile ducts via the peribiliary capillary plexus due to arterial hypotension. Gastroenterologists should be aware of this disease in patients with persistent cholestasis after severe trauma.
