ABSTRACT Objective: to evaluate the role of abdominal computed tomography in the management of penetrating abdominal trauma. Methods: we conducted a historical cohort study of patients treated for penetrating trauma in the anterior abdomen, dorsum or thoracoabdominal transition, that were submitted to a computed tomography carried out on admission. We evaluated the location of the wound and the presence of tomographic findings, and the management of these patients as for nonoperative treatment or laparotomy. We calculated the sensitivity and specificity of computed tomography according to the evolution of the nonoperative treatment or the surgical findings. Results: we selected 61 patients, 31 with trauma to the anterior abdomen and 30 to the dorsum or thoracoabdominal transition. The mortality rate was 6.5% (n=4), all in the late postoperative period. Eleven patients with trauma to the anterior abdomen were submitted to nonoperative treatment, and 20, to laparotomy. Of the 30 patients with trauma to the dorsum or thoracoabdominal transition, 23 underwent nonoperative treatment and seven, laparotomy. There were three nonoperative treatment failures. In penetrating trauma of the anterior abdomen, the sensitivity of computed tomography was 94.1% and the negative predictive value was 93.3%. In dorsal or thoracoabdominal transition lesions, the sensitivity was 90% and the negative predictive value was 95.5%. In both groups, the specificity and the positive predictive value were 100%. Conclusion: the accuracy of computed tomography was adequate to guide the management of stable patients who could be treated conservatively, avoiding mandatory surgery in 34 patients and reducing the morbidity and mortality of non-therapeutic laparotomies.

Abdominal trauma, one of the leading causes of death under the age of 45, can be broadly classified into blunt and penetrating trauma, based on the mechanism of injury. Blunt abdominal trauma usually results from motor vehicle collisions, fall from heights, assaults, and sports and is more common than penetrating abdominal trauma, which is usually seen in firearm injuries and stab wounds. In both blunt and penetrating abdominal trauma, an optimized imaging approach is mandatory to exclude life-threatening injuries. Easy availability of the portable ultrasound in the emergency department and trauma bay makes it one of the most commonly used screening imaging modalities in the abdominal trauma, especially to exclude hemoperitoneum. Evaluation of the visceral and vascular injuries in a hemodynamically stable patient, however, warrants intravenous contrast-enhanced multidetector computed tomography scan. Dual-energy computed tomography with its postprocessing applications such as iodine selective imaging and virtual monoenergetic imaging can reliably depict the conspicuity of traumatic solid and hollow visceral and vascular injuries.

Background and Objective: Trauma remains the major cause of mortality and disability among young people across the world with penetrating trauma being a very common cause. Traditionally, penetrating abdominal trauma was managed with exploration. But now with the advent of minimally access surgery and advancements in laparoscopic expertise, more patients can be managed with minimally invasive methods. This approach can save many unnecessary laparotomies and large midline incisions. The role of laparoscopy in blunt abdominal trauma is well established. The aim of this study was to evaluate the role of diagnostic laparoscopy in penetrating abdominal injuries. Methods: All the penetrating abdominal trauma patients presenting to the emergency department of Rawal Medical and Dental hospital from January 2019 till December 2020 for a period of 2years (a total of 102 patients) and who were hemodynamically stable, between the ages of 20 to 50 years of either gender were included in the study. All these patients had equivocal abdominal findings with no signs to suggest serious intraabdominal injury. These patients were prepared as standard for general anesthesia and diagnostic laparoscopy was performed. A predesigned performa was used for entering the patients’ details and operative findings. All patients gave written informed consent in urdu. Main outcome measures were the conversion rate, missed injuries leading to reexploration. Results: 85%of the patients were males with only 15% females. Mean age of the population was 38.7 years .Conversion to open was required in only 6.12 % of the cases .Laparoscopy alone was sufficient for all other patients. In about 36% of the patients no intraabdominal injury was found. In rest 58% patients the surgeons were able to repair the injuries laparoscopically.18 patients had minor liver injury,10 patients had minor hemoperitoneum<100 ml without any significant injury and 2 patients had single small bowel perforation which was repaired laparoscopically and cavity was irrigated. No patient had post operative complications of peritonitis due to missed injury or bleeding leading to re exploration. Conclusion: Laparoscopy is a very effective procedure to deal with penetrating abdominal trauma patients who are stable and with equivocal abdominal findings without increasing risk of missed injury with minimal rates of conversion to open laparotomy if patients are selected vigilantly.

Abstract Background Asymmetric breast density is a potentially perplexing finding; it may be due to normal hormonal variation of the parenchymal pattern and summation artifact or it may indicate an underlying true pathology. The current study aimed to identify the role of diffusion-weighted imaging (DWI) and the apparent diffusion coefficient (ADC) values in the assessment of breast asymmetries. Results Fifty breast lesions were detected corresponding to the mammographic asymmetry. There were 35 (70%) benign lesions and 15 (30%) malignant lesions. The mean ADC value was 1.59 ± 0.4 × 10–3 mm2/s for benign lesions and 0.82 ± 0.3 × 10–3 mm2/s for malignant lesions. The ADC cutoff value to differentiate between benign and malignant lesions was 1.10 × 10–3 mm2/s with sensitivity 80%, specificity 88.6%, positive predictive value 75%, negative predictive value 91%, and accuracy 86%. Best results were achieved by implementation of the combined DCE-MRI and DWI protocol, with sensitivity 93.3%, specificity 94.3%, positive predictive value 87.5%, negative predictive value 97.1%, and accuracy 94%. Conclusion Dynamic contrast-enhanced MRI (DCE-MRI) was the most sensitive method for the detection of the underlying malignant pathology of breast asymmetries. However, it provided a limited specificity that may cause improper final BIRADS classification and may increase the unnecessary invasive procedures. DWI was used as an adjunctive method to DCE-MRI that maintained high sensitivity and increased specificity and the overall diagnostic accuracy of breast MRI examination. Best results can be achieved by the combined protocol of DCE-MRI and DWI.

Abstract Background:The liver is the second most injured organ following blunt abdominal trauma (BAT) after spleen. Although the computed tomography (CT) scan is considered as the gold standard for diagnosing liver injury in BAT, it is not readily available in the hospital. This study was performed to evaluate the role of aspartate transaminase (AST) and alanine transaminase (ALT) in patients with BAT and its significance in predicting the diagnosis and severity of the liver injury.Method:The study was conducted in Chitwan Medical College Teaching Hospital (CMCTH) study from February 2019 to May 2020. During that period 96 patients with BAT presented to the emergency department(ED) of CMCTH.Results:Among the 96 patients admitted with BAT, 38 patients had liver injury and 58 patients had no liver injury. The median length of the intensive care unit (ICU) stay of patients with liver injury was higher than without liver injury. There was a significant difference in the median level of AST and ALT (<0.001) between patients with liver injury and no liver injury. The area under the ROC curve of AST was 0.89(95% Confidence Interval 0.86-0.98) and of ALT was 0.92(95% Confidence Interval 0.83-0.97). The area under the curve demonstrated that the test was a good predictor for the identification of liver injury and also the severity of liver enzymes. The cut-off values for the liver injury were 106 U/l and 80 U/l for AST and ALT respectively. Based on these values, AST ≥ 106 U/l had a sensitivity of 71.7 %, a specificity of 90 %, a positive predictive value of 86.8 %, and a negative predictive value of 77.6 %. The corresponding values for ALT ≥ 80 U/l were 77.8 %, 94.1%, 92.1% and 82.8 %, respectively.ConclusionIn conclusion, we report the optimal cut-off value of AST and ALT for liver injury in BAT as ≥ 106 U/l and 80 U/l respectively. The elevated level of AST and ALT might assist the surgeons to timely refer the suspected patients with the liver to a tertiary center and it might help the surgeons to go for conservative management for minor liver injuries in BAT preventing the exposure hazards of the CT scan.

Background: Abdominal injury constitutes a significant portion of all blunt and penetrating body injuries. Computed   tomography is an important and fast technique which gives rapid information on the type of abdominal injury and helps in management of the patient accordingly. The aim of the present study was to evaluate the usefulness of Multidetector Computed Tomography (MDCT) in detection of intra-abdominal injury in patients with blunt abdominal trauma and to provide information that could accurately determine choice of management (non- operative versus operative). And to correlate the computed tomography (CT) findings with either clinical observation, follow up CT scan (if required) or surgical findings (wherever applicable).Methods: A total of 50 patients with abdominal trauma who underwent computed tomography (CT) examination were included. CT findings were compared with surgical findings in operated cases, and in the rest CT findings were compared by clinical outcome.Results: Among the 50 cases studied, all 50 had positive CT findings of abdominal trauma, out of which 24 patients underwent surgery and the remaining were managed conservatively. The age group of the patients was ranging from 8 to 66 years with male predominance. In this study the commonest organs affected were liver and spleen accounting for 48% and 44% respectively.Conclusions: Computed tomography is an important and highly sensitive imaging modality for diagnosis of organ injuries in patients with abdominal trauma and accordingly deciding the management of patient.

Introduction: The incidence of penetrating abdominal injuries has been on the rise. The common availability of rearms, the lack of proper law, armed conicts, civil violence and road trafc accidents are the major causes of penetrating abdominal injuries. As patient with penetrating abdominal trauma are at risk of harbouring life threatening injuries, early diagnosis and timely intervention is the most important steps to reduce its morbidity as well as mortality. Recently due to improvement of the present healthcare system, the outcome of these injuries is improving. Materials And Methods: A descriptive observational study was carried out on 60 cases of penetrating abdominal injuries. A predesigned pretested schedule was used for data collection. Interview of the study subject and evaluation of all clinical reports was done to obtain the history, clinical ndings, management, complications, mortality and follow up. Before data collection, informed consent was obtained from each and every study subjects. Results: The overall incidence of penetrating abdominal trauma was found to be 2.30% of the total admission of 6217 patients in the department of surgery. The most common cause of penetrating abdominal injury found in this study is stab injury by sharp objects which is followed by gunshot injury. The commonest age group affected was 20 to 30 years which comprises about 41.67%. In this study we found a male preponderance in cases of penetrating injury to the abdomen. In most of the cases the mode is homicidal stab or gunshot injury followed by accidental injuries. Pain, abdominal distension and bleeding from the wound are the main presenting symptom. After initial evaluation with USG (FAST),CTscan abdomen is the most valuable investigation so far. In this series, it is found that the small intestine is the most commonly involved viscera followed by colon, omentum, mesentery and liver respectively. Most common complications after operative intervention was wound infection. The average hospital stay was 6 to 15 days. It has been observed that the post-operative complications, associated injuries and multiple organ injuries are the cause of increased hospital stay. Conclusion: Penetrating trauma can be serious because it can damage internal organs and presents a risk of shock and infection. In the present year, due to overall improvement in the communication and transportation, better monitoring systems and resuscitative measures, improvised diagnostic methods, better availability of blood and blood products, better medications and more skilful surgical techniques, the outcomes of these injuries are improving.
