Complicated penetrating foreign body neck injury.

Penetrating neck injury is associated with significant morbidity due to the several structures (neurological, vascular and aerodigestive) within close proximity to one another. This case highlights an uncommon presentation of an embedded foreign body following penetrating neck trauma and the decision-making required during management.

'No zone' approach in the management of penetrating neck injuries - an Australian Tertiary Trauma Centre experience.

PURPOSE: Penetrating neck injuries (PNIs), defined as deep to the platysma, can result in significant morbidity and mortality. Management has evolved from a zone-based approach to a 'no zone' algorithm, resulting in reduced non-therapeutic neck exploration rates. The aim of this study was to examine PNIs and its management trends in an Australian tertiary trauma centre, to determine if a 'no zone' approach could be safely implemented in this population, as has been demonstrated internationally. METHODOLOGY: This was a retrospective observational study at a level 1 adult Australian tertiary trauma centre using prospectively collated data from January 2008 to December 2018. Observed data included age, gender, mechanism of injury, computed tomography angiography (CT-A) use and operative intervention. Patients were examined based on zone of injury and presenting signs - 'hard', 'soft' or 'asymptomatic'. Major outcomes were CT-A usage, positive CT-A correlation with therapeutic neck explorations and negative neck exploration rates. RESULTS: This study identified 238 PNI patients, with 204 selected for review. Most injuries occurred in zone 2 (71.6%), with soft signs accounting for 53.4% of cases. Over 10 years, CT-A utilization increased from 55% to 94.1%, with positive CT-As being more likely to yield therapeutic neck explorations. There was a general decreased trend in operative intervention but without a clear reduction in non-therapeutic neck explorations. CONCLUSION: Our data suggests similarities with results from around the world, demonstrating that the 'no zone' approach should be considered when managing PNIs, but with clinician discretion in individual cases.

Management of contained penetrating cardiac injury in a patient with prior cardiac surgery.

Penetrating cardiac injuries usually require emergent surgical intervention. Our patient presented to the trauma centre with multiple stab wounds to the neck, chest, epigastric region and abdomen. She arrived haemodynamically stable, and her initial Focused Assessment with Sonography for Trauma exam was negative. Her chest X-ray did not show any evident pneumothorax or haemothorax. Due to her injury pattern, she was taken to the operating room for exploratory laparotomy and neck exploration. Postoperatively, she was taken for CT and found to have a contained cardiac rupture. The injury was contained within previous scar tissue from her prior cardiac surgery. Further evaluation revealed that the injury included a penetrating stab wound to the right ventricle and a traumatic ventricular septal defect (VSD). She subsequently underwent a redo sternotomy with the repair of the penetrating stab wound and the VSD. Cardiology, intensive care, trauma surgery and cardiothoracic surgery coordinated her care from diagnosis, management and recovery. This case highlights the challenges in the management of cardiac injuries and the benefits of a multidisciplinary approach to care for complex cardiac injuries.

Clinical Reasoning: A 24-Year-Old Woman With Penetrating Neck Injury From a Needlefish.

Evaluating patients with a traumatic spinal cord injury can be complicated by other injuries. In this case, a 24-year-old woman injured by a needlefish presented with combined motor and sensory defects, cranial nerve deficits, and a blunt vascular injury. This case highlights the importance of neurologic and vascular localizations and an understanding of spinal cord injuries involving various ascending and descending tracts. Appreciation of these anatomical considerations through this case illustrates the diagnostic approach to neurologic evaluation. While we present a traumatic etiology for multiple neurologic syndromes, this case gives readers an opportunity to develop a comprehensive differential diagnosis and tailor investigations for other relevant etiologies. Readers walking through this stepwise process will ultimately arrive at several distinct but related diagnoses.

An intricate vagina penetrating injury with a 22 cm cassava stick in situ for 6 months: a case report.

BACKGROUND: Trauma remains one of the major causes of morbidity and mortality and a threat to attainment of sustainable development goal 11. Genital urinary trauma is reported in about 10% of patients presenting with trauma worldwide, and in about 6.6% of patients in Sub-Saharan Africa. If not careful enough, one may miss the foreign body in the vagina and this may be associated with morbidity, and although  rare, mortality. CASE PRESENTATION: We report a case of a 7-year-old Black Ugandan that had suffered vagina trauma 6 months prior to presentation at our facility and presented with chronic vagina pus discharge for 6 months. Prior examinations had failed to recognize the foreign body and so did the two abdominal pelvic ultrasound scans. During examination under anesthesia, we were able to locate the cassava stick that had caused penetrating vagina injury and we were able to dislodge it. It was a blunt cassava stick with length of 22 cm and diameter of 2 cm. Although it had gone through the peritoneal cavity, we did not do a laparotomy. CONCLUSION: This case emphasizes the need for a thorough vaginal exam including the need to do it under anesthesia with good lighting even when ultrasound scan findings are normal. It presents an opportunity for one to manage penetrating peritoneal injury without a laparotomy in highly selected cases. Gynecologists should be keen as well to rule out child molestation.

Pediatric case of a penetrating lumbar spinal injury.

PURPOSE: Penetrating spinal injuries are generally extremely rare and are seldom encountered in pediatric patients. The non-compliance of pediatric patients with physical examination can sometimes delay diagnosis and treatment. Here, we present a case of a child who had a fall and suffered penetrating spinal trauma due to a small glass fragment. CASE REPORT: A penetrating foreign body was detected in the lumbar spinal region of a 2-year-old patient with complaints of increased restlessness on physical activity followed by difficulty in walking. The patient was operated on and followed up without any complications in the perioperative and late postoperative periods. CONCLUSION: A detailed physical examination is necessitated in the pediatric age group because of insufficient anamnesis. The high number of patients per physician, especially in societies having a low socioeconomic standard, prevents detailed examinations, and unnecessary examinations may cause delays in diagnosis. However, one must note that the skin findings of pediatric patients can be very helpful, especially in pediatric neurosurgery, and examination should not be neglected.

Surgical exploration for penetrating neck trauma - an audit of results in 145 patients.

BACKGROUND: Selective non-operative management (SNOM) is the current gold standard for the treatment of patients with penetrating neck trauma. The policy revolves around the liberal use of computed tomography angiography (CTA) in those patients who are haemodynamically stable, irrespective of the anatomical zone of injury, aiming at reducing the incidence of negative and non-therapeutic interventions and their potential complications. METHODS: A retrospective audit of results of patients who underwent immediate surgical exploration at the Chris Hani Baragwanath Academic Hospital in Soweto between January 2010 and December 2015 was performed. RESULTS: One-hundred and forty-five (145) patients, with a median age of 28 years (range 18-67 years), predominantly males (93.8%), underwent immediate exploration. Most injuries were caused by stab wounds (92.4%) and affected zone 2 (54.1%) on the left side of the neck (69.6%). The most common presentations were active haemorrhage (29.4%), shock (24.1%) and expanding haematoma (15.1%). A major vascular injury was found in 40%, and aero-digestive organ injury in 19.3%. The rate of negative-non-therapeutic exploration in this cohort was 4.1%. Complications were recorded in 7.6%, and the overall mortality was 9.6% secondary to early uncontrolled haemorrhage, sepsis and occlusive strokes. CONCLUSIONS: The utilisation of SNOM with strict criteria for selection of patients who require immediate surgical exploration versus investigations with CTA results in a low rate of non-therapeutic interventions.

Diagnostic utility of multidetector CT scan in penetrating diaphragmatic injuries: A systematic review and meta-analysis.

Penetrating diaphragmatic injuries pose diagnostic and management challenges. Computed tomography (CT) scans are valuable for stable patients, but concern exists for missed injuries and complications in nonoperatively managed cases. The objective of this study was to explore the diagnostic utility of multidetector CT scan (MDCT) in identifying diaphragmatic injuries resulting from penetrating trauma. A systematic review and meta-analysis were conducted, following established guidelines, by searching PubMed, Scopus, Web of Science, and Embase databases up to July 6, 2023. Eligible studies reporting MDCT's diagnostic accuracy in detecting penetrating diaphragmatic injuries were included. Relevant data elements were extracted and analyzed using STATA software. The study included 9 articles comprising 294 patients with confirmed penetrating diaphragmatic injuries through surgical procedures. MDCT's diagnostic performance revealed a pooled sensitivity of 74% (95% CI: 56%-87%) and a pooled specificity of 92% (95% CI: 79%-97%) (Fig. two), with significant heterogeneity in both sensitivity and specificity across the studies. The Fagan plot demonstrated that higher pre-test probabilities correlated with higher positive post-test probabilities for penetrating diaphragmatic injury diagnosis using MDCT, but even with negative results, there remained a small chance of having the injury, especially in cases with higher pre-test probabilities. This study highlights MDCT's effectiveness in detecting diaphragmatic injury from penetrating trauma, with moderate to high diagnostic accuracy. However, larger sample sizes, multicenter collaborations, and prospective designs are needed to address observed heterogeneity, enhancing understanding and consistency in MDCT's diagnostic capabilities in this context.

Is diagnostic laparoscopy necessary in the management of left thoracoabdominal stab wounds?

BACKGROUND: The diagnosis of a diaphragmatic rupture and the identification of patients for surgical repair is challenging despite current diagnostic algorithms and imaging technologies. Unless treated on time, acute traumatic diaphragmatic injury due to stab wounds has a high mortality and morbidity rate, with an increasing trend in the presence of organ herniation. In this study, we aimed to investigate the efficacy of diagnostic laparoscopy in patients with an anterior thoracoabdominal stab wound and to compare the follow-up outcomes of cases. METHODS: We retrospectively reviewed our institutional database of patients who were admitted with stab wounds between Oc-tober 2012 and 2022. Patients who underwent diagnostic laparoscopy were divided into two groups depending on the presence of a diaphragmatic injury. We analyzed demographics, the success of computed tomography (CT) imaging in the diagnosis, the presence of hemomediastinum, pneumomediastinum, tube thoracostomy application, associated organ injury, type of surgery, duration of surgery, complications, and the length of stay between the groups. RESULTS: Of the 39 patients with penetrating left thoracoabdominal injury underwent diagnostic laparoscopy, CT had a diagnostic sensitivity of 63.16% (95% Confidence interval [CI] 38.36-83.71%), and a specificity of 100% (95% CI 82.35-100.00%). We could not find a statistically significant difference between the groups in terms of studied variables, while operation time was significantly higher in the diaphragmatic injury group (P<0.01). Fourteen patients had accompanied visceral injuries. CONCLUSION: Diagnostic laparoscopy is still the gold standard particularly in the ER setting, particularly in the absence of an experienced radiologist for 24 h and when the close monitoring of the patient by the same team cannot be provided.

Penetrating carotid artery injury by air rifle: a case report.

BACKGROUND: Air rifle injuries can cause significant vascular injuries. This air rifle injury has resulted in a penetrating neck trauma traversing the common carotid artery. There is debate around the need for radiological investigation, the most appropriate investigational modality, and the need for surgical exploration versus a conservative approach. This case report aims to exemplify a successful approach to managing Penetrating Carotid Injuries (PCI) while shedding light on the rationale behind the management decisions. PRESENTATION: An 18-year-old Caucasian man arrived at the hospital following an air rifle injury to the right side of the neck, with active bleeding and a moderate haematoma displacing the trachea. He was haemodynamically stable, with a Glasgow Coma Scale (GCS) of 15 and no evidence of bruit. Computed Tomography Angiography (CTA) showed Right common carotid (CCA) artery injury with associated post-traumatic pseudoaneurysm. The pellet trajectory traverses the right superior thyroid gland. A duplex ultrasound scan (USS) confirmed two areas of arterial blush at the right CCA. Management involved neck exploration under General Anaesthesia (G.A.), repair of right CCA, bullet extraction, and wound washout. He received antibiotics for ten days and a single agent of antiplatelets for three months and was discharged two days postoperatively with no complications. He was followed up for eight months with no evidence of any trauma sequelae. CONCLUSION: Penetrating carotid artery injuries are a serious concern. The small-sized pellets carry the risk of embolization. Therefore, neck exploration remains the gold standard treatment for PCI. Appropriate operative planning is crucial and can be optimised using radiological diagnostic modalities in haemodynamically stable patients. CTA is a non-invasive, swift, and adequate alternative to arteriography, providing valuable diagnostic information on vascular and aerodigestive injuries and bullet trajectory. This enables appropriate preparedness to achieve excellent outcomes in such critical cases.

Concordance of CT imaging and surgical lesions in penetrating abdominal trauma.

OBJECTIVE: The management of penetrating abdominal wounds has greatly benefited from the development of computed tomography (CT), particularly in stable patients. In this setting, the scanner is the reference examination. Our study aims to evaluate the performance of preoperative CT in the assessment of penetrating abdominal lesions. MATERIAL AND METHODS: Between January 1, 2015 and January 1, 2022, 81 patients were hospitalized following penetrating abdominal trauma at the Army Training Hospitals of Sainte-Anne and Laveran. Fifty-one stable patients who had an abdominopelvic CT scan and thereafter underwent abdominal surgery (laparotomy or laparoscopy) were included. Radiological and surgical data were collected from the electronic record and compared by a descriptive analysis (calculation of the sensitivity, specificity, positive and negative predictive value of the CT for the detection of lesions of the various organs) and by a correlation of the CT findings with surgical findings using Kripendorff's alpha coefficient. RESULTS: The cohort was largely male (n=45; 88%), with injuries by knife wound in 62.7% of cases (n=32) and gunshot in 35.3% (n=18) of cases. The median age was 36years (25-47). The median index of severity score (ISS) was 17 (10-26). Excellent agreement between predicted and actual findings was obtained for solid organs (α=0.801) with high sensitivity and specificity (81.8% and 96.6%, respectively). The largest discrepancies were observed for the hollow organs (α=26.2%, sensitivity of 53.3% and specificity of 76.2%) and the diaphragm (α=67.3%, sensitivity 75%, specificity 92.3%). Surgical exploration was non-therapeutic for five patients (9.8%). The failure rate for non-operative treatment was 10% (n=1). CONCLUSION: CT detection of solid organ lesions in patients with penetrating abdominal wounds is excellent. However, the detection of hollow organ and diaphragmatic wounds remains a challenge with a risk of over- and underdiagnosis. Laparoscopic exploration should be able to fill in the gaps in the CT findings.

Preoperative computed tomography, surgical treatment and long-term outcomes of dogs with abscesses on migrating vegetal foreign bodies and oropharyngeal stick injuries: 39 cases (2010-2021).

OBJECTIVES: This study evaluated success rates of surgical treatment of head and neck abscesses and draining tracts for suspected migrating vegetal foreign body and oropharyngeal penetrating injuries, and compared the outcomes according to whether a vegetal foreign body was identified in preoperative computed tomography (CT) examination. MATERIALS AND METHODS: This retrospective study involved 39 dogs that underwent CT and subsequent surgical exploration of abscesses and/or draining tracts in the head and neck, in a single institution between 2010 and 2021. Recorded data included signalment, history, physical examination, CT and surgical findings. The postoperative follow-up period was at least 8 months. Cases were classified according to whether a foreign body was identified on CT or was only suspected because of the presence of cavities and/or draining tracts on CT. RESULTS: A vegetal foreign body was identified on CT in 11 of 39 cases and later confirmed at surgery in 10 cases. In 28 of 39 cases, a vegetal foreign body was not identified on CT, but in seven of these 28 cases it was found at surgery. Resolution of clinical signs was achieved in 11 of 11 cases when a vegetal foreign body was identified on CT and in 26 of 28 cases without a foreign body identified on CT. Two cases of recurrence were observed in animals in which no foreign body was detected. CLINICAL SIGNIFICANCE: In this population of dogs undergoing surgery after preoperative CT scan, we observed resolution of clinical signs after a single surgical procedure in 95% of the cases. All animals in which a foreign body was identified were cured.

Dangerous passage: the utility and accuracy of modern chest computed tomography in penetrating thoracic injuries with potential transmediastinal trajectory.

AIM: The aim of this study is to evaluate utility and reliability of chest CT as a standalone screening modality for stable patients with thoracic GSWs and potential transmediastinal trajectories. METHODS: All patients with thoracic GSWs over a 5-year period were identified. Unstable patients requiring immediate surgery were excluded and the remaining underwent chest CT with intravenous contrast. Sensitivity and specificity for clinically significant injuries were tested against an aggregate gold standard of discharge diagnosis including imaging, operative and clinical findings. RESULTS: A total of 216 patients met inclusion criteria and underwent chest CT. After imaging, 65 (30.1%) had indication for immediate surgery, of which 10 (4.6%) underwent a thoracic procedure for chest injuries while 151 (69.9%) were selected for nonoperative management (NOM). 11 (5.1%) required a delayed thoracic operation, none due to injuries missed on CT. The remaining 140 (64.8%) underwent successful NOM. Up to 195 (90.3%) patients had successful NOM of thoracic injuries. Only 9.2% required additional imaging, all negative. CT identified a cardiac injury in one case and a vascular injury in two cases, all confirmed by surgery, while one thoracic IVC injury missed on CT was found intraoperatively. 2 patients had CT suspicious for esophageal injury, ruled out by following investigations. There was one death in the total cohort, none in the NOM group. CONCLUSIONS: Modern high-quality CT provides highly accurate and reliable screening modality for penetrating chest and mediastinal injuries and can be used as a standalone study in most patients or to guide further tests. Chest CT facilitated successful NOM.

Impact of Postoperative Imaging Following Emergency Surgery for Penetrating Ballistic Thoracic Trauma.

INTRODUCTION: Patients undergoing emergent surgical procedures after penetrating trauma can benefit from postoperative imaging studies to identify potential missed injuries or indications to additional surgery. Aim of this study is to describe postoperative imaging findings in patients who underwent emergent operation for thoracic gunshot wounds (GSWs) and the subsequent need for further surgery, diagnostic evaluations or consults. METHODS: Patients who survived to receive imaging evaluation after emergency surgery for penetrating chest trauma in a level I trauma center between 2017 and 2021 were included. Results of postoperative diagnostic evaluation were screened to determine their impact on the subsequent management. RESULTS: Overall, 125 patients admitted with a thoracic GSW underwent an emergent surgical procedure and 29 survived to receive postoperative imaging and were included. Postoperative CT-scan was performed in 26 (89.6%) patients, echocardiography in 8 (27.5%). Other tests included esophagoscopy (1) and bronchoscopy (1). Impact on management of abnormal imaging included a new indication to surgery or additional procedures in 7 cases and need for additional imaging or consults in other 8 cases. Bone fractures and lung injuries were more often diagnosed on postoperative CT-scan. In 3 patients, abnormal echocardiographic findings led to a second cardiac operation. CONCLUSION: Following emergency surgery for penetrating trauma, completion of injury assessment with CT-scan can lead to identification of missed or additional injuries, while other imaging is indicated according to operative findings. In this study, 24.1% had additional surgical pathology identified by postoperative imaging while others had findings requiring additional studies or specialist consult evaluations.

An Evaluation of Diagnostic Tests for Aerodigestive Injuries in Penetrating Neck Trauma.

Assessment of aerodigestive injuries in penetrating neck trauma (PNT) is currently left up to the discretion of physicians which can result in a lot of confusion and unnecessary testing. This study was performed at a level 1 trauma center to assess the role of computed tomography arteriogram (CTA) in evaluating for aerodigestive injury in PNT. A total of 242 patients met criteria, with ages ranging from 7 to 86 years. Computed tomography arteriogram, EGD, esophagography, and bronchoscopy were classified into positive, negative, and indeterminate results. Computed tomography arteriogram was then further analyzed for violation of the carotid sheath, investing, pretracheal, and deep cervical fascias. Results showed a high sensitivity and NPV (100%) of CTA in assessing aerodigestive injury. Computed tomography arteriogram is a reliable first-line screening tool for aerodigestive injury. EGD appears more useful than esophagography at identifying esophageal injuries. Esophagography and bronchoscopy should be reserved to aid in injury management decision-making rather than as screening studies.

An unusual presentation of penetrating bladder injury with vesicocutaneous fistula: a case report.

BACKGROUND: Blunt trauma to the urinary bladder is common with penetrating injury being a rare occasion. Most common entry pint for penetrating injuries includes buttock, abdomen and perineum with thigh being rare. There are a number of complications that may develop as a result of penetrating injury with vesicocutanous fistula being a rare occurrence that usually presents with typical sign and symptoms. CASE PRESENTATION: We present a rare case of penetrating bladder injury through medial upper thigh as an entry point that had complicated into vesicocutaneous fistula with atypical presentation of long-standing pus discharge that had been managed by incision and drainage several times with no success. MRI demonstrated a presence of fistula tract and a foreign body (piece of wood) in-situ confirmed the diagnosis. CONCLUSION: Fistulas are a rare complication of bladder injuries and can cause negative impact on the quality of life of patients. Delayed urinary tract fistulations and secondary thigh abscesses are uncommon therefore a high index of suspicion is needed for early diagnosis. This case emphasizes the importance of radiological tests in aiding the diagnosis and ultimately proper management.

Comprehensive Management of the Patient With Traumatic Cardiac Injury.

Cardiac injuries are rare but potentially life-threatening, with a significant proportion of victims dying before arrival at the hospital. The in-hospital mortality among patients who arrive in-hospital alive also remains significantly high, despite major advancements in trauma care including the continuous updating of the Advanced Trauma Life Support (ATLS) program. Stab and gunshot wounds due to assault or self-inflicted injuries are the common causes of penetrating cardiac injuries, while motor vehicular accidents and fall from height are attributable causes of blunt cardiac injury. Rapid transport of victim to trauma care facility, prompt recognition of cardiac trauma by clinical evaluation and focused assessment with sonography for trauma (FAST) examination, quick decision-making to perform emergency department thoracotomy, and/or shifting the patient expeditiously to the operating room for operative intervention with ongoing resuscitation are the key components for a successful outcome in cardiac injury victims with cardiac tamponade or exsanguinating hemorrhage. Blunt cardiac injury with arrhythmias, myocardial dysfunction, or cardiac failure may need continuous cardiac monitoring or anesthetic care for operative procedure of other associated injuries. This mandates a multidisciplinary approach working in concert with agreed local protocols and shared goals. An anesthesiologist has a pivotal role to play as a team leader or member in the trauma pathway of severely injured patients. They are not only involved in in-hospital care as a perioperative physician but also participate in the organizational aspects of prehospital trauma systems and training of prehospital care providers/paramedics. There is sparse literature available on the anesthetic management of cardiac injury (penetrating as well as blunt) patients. This narrative review discusses the comprehensive management of cardiac injury patients, focusing on the anesthetic concerns and is guided by our experience in managing cardiac injury cases at Jai Prakash Narayan Apex Trauma Center (JPNATC), All India Institute of Medical Sciences, New Delhi. JPNATC is the only level 1 trauma center in north India, providing services to a population of approximately 30 million with around 9000 operations being performed annually.
