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.

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.
