Objective To investigate the reasons of misdiagnosis and missing diagnosis in blunt abdominal trauma (BAT), and to put forward effective preventive measures. Methods Literature on BAT diagnosis in recent years was reviewed. Results Misdiagnosis and missing diagnosis, which can take place in every segment of BAT patients, were still quite common nowadays. Conclusion Detailed case history collecting, faithful medical examination and making good use of assistant examinations can efficiently decrease the misdiagnosis and missing diagnosis rates of BAT patients.
Objective To evaluate the role of CT in diagnosis of the gastrointestinal tract rupture after blunt abdominal trauma. MethodsTwenty preoperative CT scans and clinical data were obtained in 20 patients who subsequently had bowel ruptures verified surgically. CT findings were analyzed retrospectively in these patients. Retrospective interpretation was made by consensus of at least two radiologists. ResultsTwenty cases of CT scan showed intraperitoneal fluid (18 cases), pneumoperitoneum (18 cases), extravasations of gastrointestinal tract contents (2 cases), bowel wall findings (14 cases) and mesenteric injury (15 cases). Conclusion CT is fast, sensitive and noninvasive in diagnosis of the gastrointestinal tract rupture after blunt abdominal trauma.
