Although in some of the previous published literature they believe that it is rare to see false-negative results when screening with US (1%) [5, 6]. It seems that screening BAT with FAST will lead to under diagnosis in some abdominal injuries such as; retroperitoneal (pancreatic and adrenal),

vascular injuries and diaphragmatic rupture that may have a negative impact on the CP673451 patients outcome [7]. Due to subtle findings FAST has been reported to be of less value in detection of bowel and mesenteric injuries [8]. Although it is uncommon to develop hollow visceral organ injury after BAT but they are very important to diagnose, because there is no conservative treatment for these types of injuries and all of the patients with such injuries even in unequivocal cases, they need to undergo operative intervention [9]. According to the previous reports the morbidity of gastrointestinal tract injury is mostly related to delays diagnosis [10]. Because selleck chemicals llc of less ON-01910 in vitro availability of computed tomography in developing country, the purpose of our study was to determine the role of repeated abdominal US in the patients with negative “” FAST “”to early diagnose hollow viscous organ injury in patients with BAT. To our best knowledge this is the first report evaluating the role of repeated abdominal sonography to

determine and reduce missed gastrointestinal injury by FAST technique. Methods This retrospective study was started from September 2007 to July 2011. On thousand five hundred and fifty emergency ultrasonography with FAST technique were performed in our University hospital in order to detect free intra-abdominal fluid as an indicator of intra-abdominal Tolmetin organ injury in-patient with BAT (Figure 1, 2). Figure 1 Longitudinal sonogram show free fluid (arrow) associated

with Ileal perforation in pelvic cavity. Figure 2 Ultrasonogram revealed free fluid in the paracolic gutter (right) and perisplenic (left). The outcome of FAST technique and the data regarding type of abdominal injuries were obtained by retrospectively going through patient’s operation notes. After retrospectively reviewing the operation record of 1550 BAT patients, 88 were found to have gastrointestinal injury. This study was performed in Imam training University Hospital that serves as the only trauma referral center in our provenance. University review board and ethic committee approved the study. All the injured patients were referred to our center, maximum one hour after trauma and US examination was performed during first 30 minutes of admission. Examination was performed by one radiologist in the department of radiology at the emergency room. FAST technique was performed by using Sonoline G 40 ultrasound devise (Siemens, Germany) with 3.5-5 MHZ convex transducer. Six areas of the abdomen were examined to detect free fluid; left upper quadrant (LUQ), Morrison pouch, right upper quadrant (RUQ), pelvis, right and left para-colic gutters.
