The Value Of CT In The Diagnosis Of Blunt Abdnominal Trauma

Objective：To discuss the value of CT on qualitative,positioning inthe diagnosis of blunt abdominal trauma.Methods: Analyzed retrospectively88patients operated because ofblunt abdominal trauma from January2010to January2013in ourhospital. Intraoperative findings and postoperative pathology is regard asthe final clinical diagnosis.All patients had a complete B-ultrasound andCT data. The patient group: According to the position of injury, thepatients are divided into solid visceral injury group and cavity viscerainjury group.The doctor group: High qualification surgeons and theyoung doctor.To discuss the value of CT and the influence of differentqualification doctor in diagnosing blunt abnominal trauma.Results:①Qualitative diagnosis of blunt abdominal trauma:In the88patients,80cases are diagnosed by CT,so the accuracy rate is90.9%(80/88).74cases are diagnosed by B-ultrasound,so the accuracyrate is84.1%(74/88). Comparing two methods in qualitative diagnosis ofblunt abdominal trauma, there is significant difference (P <0.05).②Positioning diagnosis of blunt abdominal trauma:A total of95injuriesexist in the88patients,including71cases of solid viscus injuries and24cases of hollow viscus injuries.84cases including solid viscus injuries 64cases and hollow viscus injuries20cases are diagnosed by CT,so theaccuracy is separately88.4%(84/95),90.1%(64/71) and83.3%(20/24).70cases including solid viscusl injuries56cases andhollow viscus injuries14cases are diagnosed by ultrasound,so theaccuracy is separately73.7%(70/95),78.9%(56/71) and58.3%(14/24).Comparing the accuracy of CT and ultrasound indiagnosis of solid viscus injuries,there is signifcantdifference(P<0.05).Comparing the accuracy of CT and ultrasound indiagnosis of hollow viscus injuries,there is signifcant difference(P<0.05).③Diagnosis of CT and ultrasound in different solid viscus injuries:thediagnosic accuracy of CT and ultrasound in hepatic injuries is separately86.3%,81.8%.Comparing two methods in diagnosis of hepatic injuries,there is no difference(P>0.05). The diagnosic accuracy of CT andultrasound in splenic injuries is separately95.2%,88.1%.Comparing twomethods in diagnosis of splenic injuries, there is no difference(P>0.05).The diagnosic accuracy of CT and ultrasound in pancreatic injuries isseparately71.4%,14.2%.Comparing two methods in diagnosis ofpancreatic injuries,there is signifcant difference(P<0.05).④Thediagnostic accuracy of different qualification doctors in blunt abdominaltruama is seperately73.9%(65/88),34.1%(30/88).Kappa is0.085,0<K<0.2,poor consistency. There is significant difference betweenthem(P <0.05). Conclusion:1.On qualitative and positioning diagnosis of bluntabdominal trauma, the accuracy of CT is higher than ultrasound.2. In thediagnosis of different solid viscus injuries,the accuracy of CT is higherthan ultrasound.3. CT should be as one of routine auxiliary examinationin patients of blunt abdominal trauma.4.Participation of highqualification doctor is helpful to early diagnose blunt abnominal traumaand take timely treatment.
