ارزش سونوگرافی در تشخیص صدمات احشای داخل شکمی ناشی از ضربه

Background and Aim: Abdominal Trauma seems to be one of the most common etiological factors of mortality in human populations following encountering different types of trauma. This study was designed to evaluate the role of sonography in clinical diagnosis of internal injuries of abdomen as well as verification and confirmation of the presence of free liquids in the abdominal cavity. This study was conducted to compare the importance of the role of sonography results with the clinical trend of trauma, specially the results of surgical operations in the studied cases. Materials and Methods: The present periodic study was conducted on all 104 patients (80 males and 24 females) who referred to Ali-ibne Abitaleb Hospital of Rafsanjan due to penetrating and blunt abdominal trauma between January 2000 and April 2001. Personal characteristics of the patients such as age, cause of trauma, nature of the problem (fixed or temporary), clinical examination result, sonography result, laparatomy result-if done-, and the final diagnosis were recorded. Then, positive and negative results of sonography were matched with those of laparotomy and clinical trend. Finally, the obtained data was analyzed by EPI-5 software using chi-square test at the significant level of P= 0.05. Results: Totally, sonography was done on 104 patients with abdominal trauma, who had homeodynamic status.. Presence of free fluid in the abdominal cavities of some patients, as well as possible visceral lesions and gross pathologic changes of abdominal organs were recorded. Besides, sonography findings were negative in 85 patients (81.7%) and positive in 19 cases (18.3%). After comparing sonography findings with those coincident with surgery sonography accuracy and specificity were determined 85% and 65%, respectively. Conclusion: The results of this study generally support the role of sonography as one of the primary diagnostic techniques in the patients who are affected by abdominal trauma and have constant vital clinical signs. However, in order to make decision for laparatomy and surgical treatment, physical examinations, clinical observations and using other diagnostic techniques such as CT-Scan is imperative and can be helpful.
