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)

Increased Risk

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: Trauma has become one of the most common cause of hospitalization. The main reason for imaging and screening the patients is to identify the life-threatening injuries as soon as possible so that appropriate treatment can be given immediately.  In the past few years, both USG and CT have been widely used to detect the abdominal trauma and have replaced the older methods. This study was undertaken to compare the efficacy of CT scans and Ultrasound in the patients with blunt abdominal trauma.Methods: Patients who had come to our hospital with blunt abdominal trauma and who were stable enough to undergo both USG and CT scans were included into the study. Apart from routine tests, both USG and CT scans were performed for all the patients.Results: The most common cause of trauma was road or vehicular accidents (58.9%) followed by fall from heights (32.1%). Of the organs which were affected, the most one was liver (73.2%), followed by spleen (51.8%), 46.4% of kidneys and 12.5% of the pancreas. Hemoperitoneum was identified in all the 56 patients with CT scan while the same was identified only in 47 cases (83.9%) with USG.Conclusions: CT scan is a superior diagnostic tool for the detection of Blunt abdominal trauma compared to USG. However, the patient needs to be hemodynamically stable for CT to be performed.

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 Diagnosis of aortic graft infection is challenging, and delayed diagnosis is associated with poor prognosis. Positron emission tomography/computed tomography (PET/CT) has improved diagnostic accuracy. Case summary A patient with a history of congenital heart disease was admitted due to fever. He had a history of four cardiac surgeries, including the Bentall procedure for endocarditis. Blood cultures were negative. A semi-mobile mass was detected in the distal portion of the aortic tube graft in echocardiography. PET/CT scan was used to confirm tube graft infection and to support proceeding to cardiac surgery. Discussion Using multimodality imaging, including PET/CT scan in combination with echocardiography, can improve diagnostic accuracy for the detection of aortic tube graft infection, infection of prosthetic valves, or intra-cardiac devices, especially in high-risk surgical cases.

The objective of this study was to determine diagnostic accuracy of magnetic resonance imaging (MRI) and computed tomography (CT) scans in young athletes diagnosed with spondylolysis. A cross-sectional study was used. Twenty-two young athletes (14.7 ± 1.5 years) were diagnosed as spondylolysis based on a single-photon emission CT. Following the diagnosis, participants underwent MRI and CT scan imaging tests on the same day. The sensitivity and false-negative rate of the MRI and CT scans were analyzed. MRI test confirmed 13 (+) and 9 (−) results while CT test showed 17 (+) and 5 (−) results. The sensitivity and false-negative rate of MRI were, respectively, 59.1% (95% confidence interval [CI] = 36.7% to 78.5%) and 40.9% (95% CI = 21.5% to 63.3%). Furthermore, the sensitivity and false-negative rate of CT scan were 77.3% (95% CI = 54.2% to 91.3%) and 22.7% (95% CI = 0.09% to 45.8%). Our results indicated that CT scan is a more accurate imaging modality to diagnose spondylolysis compared with MRI in young athletes.
