Background and Aims Laparotomy can detect bowel and mesenteric injuries in 1.2%–5% of patients following blunt abdominal trauma. Delayed diagnosis in such cases is strongly related to increased risk of ongoing sepsis, with subsequent higher morbidity and mortality. Computed tomography (CT) scanning is the gold standard in the evaluation of blunt abdominal trauma, being accurate in the diagnosis of bowel and mesenteric injuries in case of hemodynamically stable trauma patients. Aims of the present study are to 1) review the correlation between CT signs and intraoperative findings in case of bowel and mesenteric injuries following blunt abdominal trauma, analysing the correlation between radiological features and intraoperative findings from our experience on 25 trauma patients with small bowel and mesenteric injuries (SBMI); 2) identify the diagnostic specificity of those signs found at CT with practical considerations on the following clinical management; and 3) distinguish the bowel and mesenteric injuries requiring immediate surgical intervention from those amenable to initial nonoperative management. Materials and Methods Between January 1, 2008, and May 31, 2010, 163 patients required laparotomy following blunt abdominal trauma. Among them, 25 patients presented bowel or mesenteric injuries. Data were analysed retrospectively, correlating operative surgical reports with the preoperative CT findings. Results We are presenting a pictorial review of significant and frequent findings of bowel and mesenteric lesions at CT scan, confirmed intraoperatively at laparotomy. Moreover, the predictive value of CT scan for SBMI is assessed. Conclusions Multidetector CT scan is the gold standard in the assessment of intra-abdominal blunt abdominal trauma for not only parenchymal organs injuries but also detecting SBMI; in the presence of specific signs it provides an accurate assessment of hollow viscus injuries, helping the trauma surgeons to choose the correct initial clinical management.

Background: Abdominal trauma can be mysterious to some practitioners. If patients are evaluated for being stable or unstable, then abdominal trauma can be easily managed. Using a combination of physical examination, eFAST Scan, DPL and CT scans, patients can be quickly and efficiently evaluated. Objectives: To determine the positive predictive value (PPV) of computed tomography and diagnostic peritoneal lavage for diagnosis of solid organ damage in patients with blunt abdominal trauma (BAT) taking surgical findings as gold standard. Study Design: Cross sectional study. Setting: Department of Surgery at Lahore General Hospital, Lahore. Period: Six months i.e. from 21.5.2016 to 20.11.2016. Materials and Methods: Data Collection: CT scan was performed with oral and intravenous contrast. DPL was done with sample assessment. Only those cases were included with positive findings in CT Scan or DPL. These patients underwent laparotomy under general anesthesia by a one standard surgical team. Results of surgical findings were compared between groups with CT scan and DPL. All the information was collected on predesigned proforma. Results: The mean age of the patients was 44.48±14.83 years. There were 66 (55%) males and 54 (45%) females in our study. In this study PPV for CT-scan group was 90.1% while PPV for group with DPL was 51.3%. Conclusion: PPV for CT Scan group was higher than that of DPL group for diagnosing solid organ damage in patients with BAT. Hence, evidence shows that CT Scan should be used as an initial investigation of choice in haemo-dynamically stable patients with BAT.

Introduction: Blunt injury trauma is regularly encountered in the emergency department. Diagnostic tools that help in optimum management of blunt abdominal trauma include; Focussed Assessment Sonography for Trauma scan, Diagnostic peritoneal lavage and Computed Tomography scan. The aim of this study is to determine the validity of CT scan as an accurate diagnostic tool and its role in management of patients with blunt abdominal trauma. Methods: A prospective analysis of 80 patients of blunt abdomen trauma who were admitted in Manipal Teaching Hospital, Pokhara, Nepal within a span of 15 months was done. Demographic data, mechanism of trauma, management and outcomes were studied. Organ injuries were graded using the Organ Injury Scale guidelines. Results: Most of the patients in our study were in the age group of 21-40 years with an M: F ratio of 2.3:1. Road traffic accident (47.5%) was the most common mechanism of injury. Spleen (27.5%) was the commonest organ injured. CT scan was superior to FAST scan and had sensitivity of 97.3% specificity 75% positive predictive value 98.6%. FAST scan had sensitivity of 78.9%, specificity 50%, positive predictive value 96% with p- value of 0.0034. 81% of patients were conservatively managed. Conclusions: In conjunction with close clinical monitoring, CT scan is reliable in the evaluation and management of blunt abdominal trauma patients. Our study also shows CT as a superior diagnostic modality compared to FAST scan. Keywords: blunt abdominal trauma; CT scan; FAST scan; road traffic accident.

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 and Aim: Blunt abdominal trauma may lead to a serious situation that necessitates prompt diagnosis and treatment. The intra-abdominal injury effective diagnosis is difficult in patient’s management in such cases. The present study aims to evaluate the diagnostic accuracy of computed tomography scans in active internal bleeding following abdominal trauma. Materials and Methods: This cross-sectional study was carried out on 84 blunt abdominal trauma patients in the Department of Radiology Hayatabad Medical Complex, Peshawar for duration of six months from January 2021 to June 2021. All the patients with no clinical manifestations underwent diagnostic CT scans. Those who had a positive CT scan underwent laparotomy. The remaining patients were monitored for 24 hours and were discharged in case of no serious issues. Demographic details, patient information, trauma mechanism, CT scan indications, and findings, and laparotomy results were recorded. Regarding injured organs, specificity, sensitivity, and diagnostic accuracy of CT scans were determined. For individual cases, CT scans specificity, sensitivity, and accuracy were calculated. SPSS version 20 was used for data analysis. Results: This study included 84 patients, out of which 73 (86.9%) were male and 11(13.1%) were female. Patients aged 20-40 years were more prevalent 47 (56%), followed by those aged over 40 years were 20 (23.8%) and 10 to 19 years old were 17 (20.2%). Liver and spleen injuries had the highest CT scan sensitivity of 87.5% and 96.7% respectively. On the other hand, The CT scan's specificity was high in the injured kidneys (94%) and retroperitoneal hematoma 97.3% compared to other organ’s injuries. The diagnostic accuracy of CT scans in the identification of liver, kidney injuries, spleen, and retroperitoneal hematoma injuries was 93.7%, 92.3%, 96.2%, and 92.3% respectively. Conclusion: Our study found that CT scans are capable of detecting a wide range of injuries. CT scans are exceptionally valuable for assessing blunt abdominal injuries with active internal bleeding patients Furthermore, CT investigation is quick and extensively accessible. CT can produce high-resolution images with MPR and scanning protocol. Keywords: Diagnostic Accuracy; Abdominal Trauma Injuries, Computed Tomography (CT)

Background: Blunt abdominal trauma is a frequent cause for presentation of children to the Emergency Department. Children are prone to sustain injuries to intra-abdominal organs after blunt abdominal trauma because of their peculiar body habitus and relatively immature musculoskeletal system. Objectives of this study is to assess the various epidemiological parameters that influences the causation of trauma as well as injury pattern in blunt trauma abdomen in pediatric population.Methods: The present observational hospital based prospective study was carried out in 96 blunt abdominal trauma patients of both sexes aged up to 12 years, over a period of 2 years. The parameters such as age group, sex, mode of trauma, type of injury, and the overall mortality as well as mortality were assessed.Results: The most common mode of injury was road traffic accidents (54.2%) followed by fall from height (41.70%). Splenic injury was the most common in 58.30%, followed by hepatic injuries 34.40% and renal injuries 12.50 %. The accuracy of ultrasonography (USG) was 83.33% while accuracy of computed tomography (CECT) as a diagnostic test was 93.33%. When comparing USG findings with operative findings sensitivity of USG was 88% with positive predictive value (PPV) of 91.66% while as specificity was 60% with negative predictive value (NPV) of 50%. Sensitivity of CT scan was 96.00% with PPV of 96.00% and specificity of CECT scan was 80.00% with NPV of 80.00%.Conclusions: The majority of pediatric injuries are preventable by knowing the epidemiology and pattern of pediatric trauma.
