Computed tomography for pancreatic injuries in pediatric blunt abdominal trauma

AIM:To evaluate the efficacy of computed tomography scan in diagnosing and grading the pattern of pancreatic injuries in children. METHODS:We conducted a retrospective study to review medical files of children admitted with blunt pancreatic injuries to the Maternity and Children Hospital Al-Madina Al-Munawwarah, Kingdom of Saudi Arabia. The demographic details and mechanisms of injury were recorded. From the database of the Picture Archiving and Communication System of the radiology department, multidetector computed tomography (MDCT) images of the pancreatic injuries, severity, type of injuries and grading of pancreatic injuries were established. RESULTS:Seven patients were recruited in this study over a period of 5 years; 5 males and 2 females with a mean age of 7 years (age range 5-12 years). Fall from height was the most frequent mechanism of injury, reported in 5 (71%), followed by road traffic accident (1 patient, 14%) and cycle handlebar (1 patient, 14%) injuries. According to the American Association for the Surgery of Trauma grading system, 1 (14%) patient sustained Grade Ⅰ, 1 (14%) Grade Ⅱ, 3 (42%) GradeⅢ and 2 (28%) patients were found to have Grade Ⅴ pancreatic injuries. This indicated a higher incidence of severe pancreatic injuries; 5 (71.4%) patients were reported to have Grade Ⅲ and higher on the injury scale. Three (42%) patients had associated abdominal organ injuries. CONCLUSION: Pediatric pancreatic injuries due to blunt abdominal trauma are rare. The majority of the patients sustained extensive pancreatic injuries. MDCT findings are helpful and reliable in diagnosing and grad- ing the pancreatic injuries.

Penetrating Abdominal Injuries: Pattern and Outcome of Management in Khartoum

Background: The pattern and presentation of penetrating abdominal trauma vary according to places and the structure of the present health system. As well controversies in management exist ranging from mandatory exploration to selective non-operative management. Objectives: To determine the pattern of penetrating abdominal trauma, current management practiced and outcome in Khartoum. Patients and Methods: The study was prospective, descriptive and hospital-based. It was carried out at the main three hospitals in Khartoum State. It was conducted over a period of one year from 2012 Mar to 2013 Mar. All patients who presented penetrating injury to their abdomen were included. Results: The study included 85 patients with a mean age of 28 years (SD ± 10). The male to female ratio was 11:1. Most of the patients (89.4%) were in the first four decades of their life. Twenty-three patients (27.1%) presented shock. Stab wound is the commonest mode of trauma seen in 83.5% of our patients. The majority of our patients were managed by exploratory laparotomy (81.2%), however 16 (18.8%) underwent conservative measures. Of the operated group, solid organ injuries were found in 22.9%, yet hollow viscous injuries were reported in 86.9% of the patients. Registrars operated on 78.26% of the patients. The rate of negative laparotomy of this study was 8.7%. Complications and mortality were encountered in 25.9% and 4.7% respectively. The mean hospital stay was 8.47 days (SD ± 10.6). Conclusion: This study demonstrates no difference in the pattern of intra-abdominal injuries. The rate of operative treatment is acceptable, but more laparotomies can be avoided if the haemodynamic stable patients without features of peritonitis were given a period of observation. The overall outcome was satisfactory.

Traumatic abdominal wall hernia:a rare and often missed diagnosis in blunt trauma

Dear editor,Traumatic abdominal wall hernia(TAWH)is defined as disruption of the abdominal wall musculature and fascia with herniation of intra-abdominal contents,in the absence of surgery to that area of the abdominal wall.[1]It is rare,with an incidence of 0.17%-0.90%in patients with blunt abdominal trauma.[2,3]Deceleration forces caused by falls from height or seat belt injuries are the most common causes of TAWH.[4]Low-energy blunt injuries from bicycle or motorcycles handlebars or charging animals are less frequent causes.Due to the rare incidence and complex presentation of this condition with other distracting injuries,this diagnosis is often not considered,resulting in missed or delayed diagnosis.We present a case of a 46-year-old male who suffered major abdominal trauma,and was found to have TAWH as well as intra-abdominal organ injury.

Clinical diagnosis and surgical treatment of pancreatic and/or duodenal injuries

Objective: To investigate the points of the clinical diagnosis and surgical treatment for pancreatic and/or duodenal injuries. Methods: Clinical data of 30 patients who suffered from pancreatic and/or duodenal injuries were reviewed. Results: There were 29 cases who received surgical management. Of the 30 cases, 22 cases were cured, seven cases died, and postoperative complications occurred in 16 cases. The cure rate was 73.3%. Conclusion: Pancreatic and/or duodenal injuries are severe abdominal injuries and difficult to treat. The mortality and complication rate are high. The keys to successful treatments for pancreatic and/or duodenal injuries are early diagnosis, careful exploration and proper operational management.

Blunt Abdominal Trauma Leading to Pancreatic Injury in Childhood. Delay in Diagnosis Leads to Poor Outcomes—A Case Presentation

This case report illustrates the difficulty in diagnosing paediatric patients with life threatening pancreatic injuries. A high index of suspicion is essential as late diagnosis significantly affects outcomes. A 9-year-old child presented with epigastric pain following an accident on his pushbike. The patient was examined in paediatric accident and emergency (A/E) and was discharged. He returned twice more to A/E and on the third visit, 5 days after the initial incident, a CT scan was performed. This showed a classical injury to the body of the pancreas with a collection in the lesser sac. The patient was transferred to the regional hepato-pancreato-biliary unit (HPB unit) and underwent surgery. Pancreatic injuries can be difficult to detect clinically and patients may be well on initial presentation with normal observations and routine bloods. Early CT scanning confirms the diagnosis and results in early specialist referral and better outcomes.

A novel machine learning-assisted clinical diagnosis support model for early identification of pancreatic injuries in patients with blunt abdominal trauma:a cross-national study

Background:The recognition of pancreatic injury in blunt abdominal trauma is often severely delayed in clinical practice.The aim of this study was to develop a machine learning model to support clinical diagnosis for early detection of abdominal trauma.Methods:We retrospectively analyzed of a large intensive care unit database(Medical Information Mart for Intensive Care[MIMIC]-IV)for model development and internal validation of the model,and performed outer validation based on a cross-national data set.Logistic regres-sion was used to develop three models(PI-12,PI-12-2,and PI-24).Univariate and multivariate analyses were used to determine variables in each model.The primary outcome was early detection of a pancreatic injury of any grade in patients with blunt abdominal trauma in the first 24 hours after hospitalization.Results:The incidence of pancreatic injuries was 5.56%(n=18)and 6.06%(n=6)in the development(n=324)and internal validation(n=99)cohorts,respectively.Internal validation cohort showed good discrimination with an area under the receiver operator characteristic curve(AUC)value of 0.84(95%confidence interval[CI]:0.71–0.96)for PI-24.PI-24 had the best AUC,specificity,and positive predictive value(PPV)of all models,and thus it was chosen as the final model to support clinical diagnosis.PI-24 performed well in the outer validation cohort with an AUC value of 0.82(95%CI:0.65–0.98),specificity of 0.97(95%CI:0.91–1.00),and PPV of 0.67(95%CI:0.00–1.00).Conclusion:A novel machine learning-based model was developed to support clinical diagnosis to detect pancreatic injuries in patients with blunt abdominal trauma at an early stage.

Abdominal compartment syndrome:Often overlooked conditions in medical intensive care units

Intra-abdominal hypertension(IAH)and abdominal compartment syndrome are well recognized entities among surgical patients.Nevertheless,a number of prospective and retrospective observational studies have shown that IAH is prevalent in about half of the critically ill patients in the medical intensive care units(ICU)and has been widely recognized as an independent risk factor for mortality.It is alarming to note that many members of the critical care team in medical ICU are not aware of the consequences of untreated IAH and the delay in making the diagnosis leads to increased morbidity and mortality.Frequently it is underdiagnosed and undertreated in this patient population.Elevated intraabdominal pressure decreases the blood flow to the kidneys and other abdominal viscera and also results in reduced cardiac output and difficulties in ventilating the patient because of increased intrathoracic pressure.When intraabdominal hypertension is not promptly recognized and treated,it leads to abdominal compartment syndrome,multiorgan dysfunction syndrome and death.Large volume fluid resuscitation is very common in medical ICU patients presenting with sepsis,shock and other inflammatory conditions like pancreatitis and it is one of the major risk factors for the development of intra-abdominal hypertension.This article presents an overview of the epidemiology,definitions,risk factors,pathophysiology and management of IAH and abdominal compartment syndrome in critically ill medical ICU patients.

Abdominal paracentesis drainage ameliorates myocardial injury in severe experimental pancreatitis rats through suppressing oxidative stress

BACKGROUND Abdominal paracentesis drainage(APD)is a safe and effective strategy for severe acute pancreatitis(SAP)patients.However,the effects of APD treatment on SAPassociated cardiac injury remain unknown.AIM To investigate the protective effects of APD on SAP-associated cardiac injury and the underlying mechanisms.METHODS SAP was induced by 5%sodium taurocholate retrograde injection in Sprague-Dawley rats.APD was performed by inserting a drainage tube with a vacuum ball into the lower right abdomen of the rats immediately after SAP induction.Morphological staining,serum amylase and inflammatory mediators,serum and ascites high mobility group box(HMGB)1,cardiac-related enzymes indexes and cardiac function,oxidative stress markers and apoptosis and associated proteins were assessed in the myocardium in SAP rats.Nicotinamide adenine dinucleotide phosphate oxidase activity and mRNA and protein expression were also examined.RESULTS APD treatment improved cardiac morphological changes,inhibited cardiac dysfunction,decreased cardiac enzymes and reduced cardiomyocyte apoptosis,proapoptotic Bax and cleaved caspase-3 protein levels.APD significantly decreased serum levels of HMGB1,inhibited nicotinamide adenine dinucleotide phosphate oxidase expression and ultimately alleviated cardiac oxidative injury.Furthermore,the activation of cardiac nicotinamide adenine dinucleotide phosphate oxidase by pancreatitis-associated ascitic fluid intraperitoneal injection was effectively inhibited by adding anti-HMGB1 neutralizing antibody in rats with mild acute pancreatitis.CONCLUSION APD treatment could exert cardioprotective effects on SAP-associated cardiac injury through suppressing HMGB1-mediated oxidative stress,which may be a novel mechanism behind the effectiveness of APD on SAP.

Incidence of unexplained intra-abdominal free fluid in patients with blunt abdominal trauma

BACKGROUND: Intra-abdominal free fluid is commonly caused by injuries of solid or hollow organs in patients suffering from blunt abdominal trauma (BAT). However, it presents a diagnostic dilemma for surgeons when free fluid is unexplained, especially in stable BAT patients. This study was to analyze the incidence of such unexplained free fluid in BAT patients and its diagnostic value in abdominal organ injury. METHODS: Altogether 597 patients with BAT who had been treated at our trauma center over a 10-year period were reviewed. Stable patients with free fluid but without free air or definite organ injury on abdominal computed tomography were studied. Clinical management and operative findings were analyzed. RESULTS: Thirty-four (5.70%) of the 597 patients met the inclusion criteria: 24 (4.02%) underwent therapeutic exploratory laparotomy: bowel injuries were found in 13, hepatic rupture in 3, colon rupture in 3, duodenal rupture in 2, spleen rupture in 1, pancreas rupture in 1, and gallbladder perforation in 1. In 2 patients, laparotomy was nontherapeutic. Those with moderate or large amounts of free fluid were more likely to suffer from a hollow viscus injury and have a therapeutic procedure. The mean time of hospital stay for the delayed laparotomy group was longer than that for the emergency group (19 5.12 vs. 12 2.24 days; t=2.73, P<0.01). CONCLUSIONS: There was a positive correlation between the amount of unexplained free fluid and the determination of intra-abdominal organ injury. The proportion of BAT patients who required surgical intervention was high, particularly those with a moderate or large amount of free fluid, and most of them suffered from a hollow organ injury. Emergency laparotomy is recommended for these patients.

Abscess rate of patients with penetrating abdominal injury in Zaria

Background: Penetrating abdominal injury occurs when a foreign object pierces the skin. The morbidity and mortality associated with penetrating abdominal trauma is related to the intra-abdominal complications. This study is, therefore, intended to determine the abscess rate resulting from penetrating abdominal trauma in Ahmadu Bello University Teaching Hospital Zaria. Method: A 6-year (January 2006-December 2011) retrospective study of penetrating abdominal trauma emphasizing on the rate of development of intra-abdominal abscess. Information was obtained from patients’ case notes, operating room log books and surgical audit data. Information extracted included cases of penetrating abdominal trauma, intra-operative findings and cases of intra-abdominal abscesses. Results: A total of 39 cases of penetrating abdominal trauma were treated within this period of six years. 3 (7.7%) were treated in 2006, 6 (15.4%) in 2007, 3 (7.7%) in 2008 and 11 (28.2%) in 2009, 8 (20.5%) in 2010, 9 (23.1%) in 2011. 26 (66.7%) were adult while 13 (33.3%) were paediatric cases. The male were 37 (94.9%) and the female were 2 (5.1%), with a sex ratio of 18.5:1 (male to female). The age range was 5 -60 years (39.92 mean). The commonest cause of injury was road traffic accident. At exploration, 13 (33.3%) had organ injury only, 17 (43.6%) suffer from both organ injury and intra-peritoneal emorrhage, 9 (23.1%) had retroperitoneal haemorrhage only. The intra-abdominal abscess rate of penetrating abdominal injury in Zaria was found to be 2.6%. Conclusion: Contamination from either foreign object or organ injury is found to increase the risk of post-operative intra-abdominal abscess. In this center, the abscess rate of penetrating abdominal trauma is comparatively low.

NonOperative Management of Blunt Solid Abdominal Organ Injury in Calabar, Nigeria

Background: Over the past several years, nonoperative management has been increasingly recommended for the care of selected blunt abdominal trauma patients with solid organ injuries. Objective: To evaluate the pattern and outcome of blunt abdominal trauma using haemodynamic stability and ultrasonography in the selection of patients for nonoperative management in a facility without computed tomogram. Methods: Patients admitted with blunt abdominal trauma between February 2005 and January 2010 were prospectively studied. Haemodynamic stability and sonography formed the basis for selecting patients for nonoperative management. Results: In total, 58 patients suffered blunt abdominal trauma and 19(33%) patients were successfully managed nonoperatively suffered blunt solid abdominal organ injuries. Road traffic accidents inflicted 17(89%) patients while 2(11%) patients sustained sports injury (football). The spleen was the commonest solid organ injured 12(60%), while the liver and kidney were injured in 6(30%) and 2(10%) respectively. Associated injuries were fractured left femur recorded in 3(16%) patients and fractured rib in a patient (5%). Conclusion: Nonoperative treatment is a safe and effective method in the management of haemodynamically stable patient with blunt solid abdominal organ injury. This translated to a reduction in hospital stay, absence of the risk of blood transfusion as well as attendant morbidity and mortality associated with laparotomy. Establishment of trauma system, provision of diagnostic and monitoring facilities, good roads, and education on road safety is recommended for improved outcome.

The Incidence of Splenic Injury Following Blunt Abdominal Trauma (BAT), Sultan Qaboos University Hospital Experience

The aim of the study was to review traumatic splenic injury following blunt abdominal trauma (BAT), during the period from January 2009 to January 2015 at SQUH. The data for this study was retrospectively collected. It included 768 patients admitted to SQUH general surgery department following BAT. 43 patients with splenic injury were identified (34 males, 9 females). The mean age of patients with splenic injury was 36.0 years (34.4 years for males, 42.1 years for females). The most common mechanism of injury was motor vehicle collision (90.7%). Grade I, II are the most common grades of splenic injury. Non-Omani patients accounted for (51.2%) and most of them were pedestrians at the time of trauma. Ribs fracture is the most common injury associated with splenic injury. 36 (83.7%) patients were managed conservatively and 7 (16.3%) patients were splenectomized. Angioembolization was done for 11 (30.6%) patients. Despite the small population of Oman, high incidence of motor vehicle collision (MVC) increases the incidence of splenic injury among young age group.

Peripheral Neuropathy after Open Abdominal Surgery with Self-Retaining Retractors. A Systematic Review of Randomised and Non-Randomised Clinical Trials

Objectives : A systematic review was undertaken to evaluate the effectiveness of incision retention available to surgeons conducting open abdominal or pelvic surgeries. Both the ability of the retractor to retain the wound and harm to the patient due to the retractor were reviewed. Methods : A search was conducted using the following databases: EMBASE, PubMed, BIOSIS, Engineering Village, Web of Science, Best practice, Science Direct, CRCnet BASE, Proquest, Wiley Online Library, and Comprehensive Biomaterial. Results : What the articles found were then narrowed down to those which matched the objective of the review. This resulted in ten articles to review. Two reviewers reviewed and summarized the articles. Femoral neuropathy was found to be a common complication due to Retractors. Other outcomes analysed or studied were found to be infected, postoperative pain and exposure provided. Femoral neuropathy can be estimated to occur at a rate between 2.6% and 7.5% in open pelvic and abdominal surgeries. The Alexis O-ring retractor was found to lower the required morphine intake following surgery when compared to the Belfour retractor. Conclusions : There is a lack of high quality/high levels of evidence studies that have been conducted on Retractors. Femoral neuropathy is the outcome most commonly documented in relation to Retractors. Surgeons need to be aware about the use and implementations of the retractors. Care should be taken in protecting the blades and during long surgery relocating retractors should be considered.

Double ischemic ileal stenosis secondary to mesenteric injury after blunt abdominal trauma

The authors describe a rare case in which blunt abdominal trauma resulted in mesenteric injury with delayed double ischemic ileal stenosis. Abdominal computed tomography demonstrated stenotic ileal loop with mural thickening. At surgery, a double stenotic bowel loop was found adjacent to a healed defect in the mesentery. Histological examination of the two resected segments showed fibrotic and ischemic lesions within the mesentery. Ischemic intestinal stenosis from mesenteric injury should be considered in the differential diagnosis in patients suffering from intestinal occlusion with a history of blunt abdominal trauma.reserved.

内分泌指标及超声检查在小儿胰腺损伤早期诊断中的应用

腹部外伤的发生率在小儿创伤中占比逐年增加,创伤性胰腺损伤应引起临床医生的足够重视。胰腺位于腹膜后,尤其是Ⅰ、Ⅱ级损伤的患儿,其早期诊断较为困难。本文通过文献复习,分析内分泌指标及腹部超声检查在小儿胰腺损伤早期诊断中的价值,以提高早诊率,避免相关并发症的发生。内分泌指标中血清胰岛素、C肽等指标的变化,对于诊断和评估小儿胰腺损伤有一定的优势,可作为小儿胰腺损伤病情的预警指标。超声弹性成像技术为胰腺损伤的诊断和鉴别提供了新的方法;而对比增强超声在识别患儿胰腺损伤中具有较高的特异度及敏感度,由于其无放射性损害,有望成为CT检查的替代方案。

降钙素原与白蛋白比值对腹腔感染引起的脓毒症相关急性肾损伤不良预后的评估价值

目的探讨腹腔感染引起的脓毒症相关急性肾损伤(AKI)的危险因素,并分析其在脓毒症相关AKI病人不良预后中的诊断价值。方法前瞻性分析南京医科大学附属淮安第一医院重症监护室(ICU)2019年1月至2022年12月231例由腹腔感染引起的脓毒症相关AKI病人的临床资料,根据病人随访预后情况将其分为生存组(137例)和死亡组(94例)。采用单因素分析法比较两组病人的临床资料;多因素logistic回归分析脓毒症相关AKI病人不良预后的独立危险因素;受试者操作特征曲线(ROC曲线)评价血清降钙素原(PCT)、C反应蛋白(CRP)、PCT/白蛋白(Alb)、CRP/Alb对脓毒症相关AKI病人不良预后的诊断价值。结果单因素分析显示,231例脓毒症相关急性肾损伤,小肠坏死或穿孔疾病引起的病死率明显高于回盲阑尾疾病的病死率(31.9%比11.7%)(P<0.001);死亡组PCT浓度显著高于生存组[28.65(18.73,78.97)mg/L比8.0(1.05,21.73)mg/L](P<0.001);同样,死亡组CRP浓度显著高于生存组[224.37(180.10,263.15)mg/L比186.3(136.33,235.84)mg/L](P<0.001);死亡组PCT/Alb和CRP/Alb比值均显著高于生存组[2.29(0.73,3.78)比0.25(0.04,0.53)和10.78(6.91,13.79)比5.75(5.30,10.92)](均P<0.001);多因素logistic回归分析显示,PCT/Alb、CRP/Alb是脓毒症诱导AKI病人不良预后的独立危险因素。进一步的ROC曲线显示,PCT/Alb预测脓毒症AKI病人不良预后的准确性均高于CRP/Alb,曲线下面积(0.86比0.74)、特异度(84.7%比61.3%)、灵敏度(78.7%比75.5%)。结论PCT/Alb不仅是评估腹腔感染引起的脓毒症相关急性肾损伤病人不良预后的独立危险因素,更能为临床改善此类疾病管理和降低病死率方面提供一定帮助。
