Abstract:【Objective】To discuss the surgical indications and the treatment results of traumatic diaphragmatic hernia(TDH)and traumatic diaphragmatic injury(TDI)treated by abdominal operation.【Methods】Retrospective analysis of 16 patients with treatment of TDH and TDI underwent abdominal surgery was conducted in terms of causes, clinical manifestation, preoperative examination, surgical approach selection and the result of surgical treatment. 【Results】Sixteen cases were included in the group: 14 males,2 females;13 left,1 right,2 double;all cases combined with united injury,11 cases combined with traumatic shock. 8 cases examined by Xray,5 diagnosed ;16 cases examined by computed tomography,135 diagnosed ; 2 cases examined by thoracoscopy,both with diaphragm injury;16 cases were treated by abdominal diaphragm repair,15 cases cured,3 cases with complications,2 cases with incision infection, 1 case with inflammatory intestinal obstruction and 1 case died of multiple organ failure.【Conclusion】 Most of TDI and TDH could be repaired by abdominal operation so as to treat bleeding of the abdominal organs timely ,and the double side of diaphragm could be examined to avoid the misdiagnosis and missed diagnosis. Meanwhile the abdominal operation could reduce the effect of respiratory and circulatory system caused by open chest operation , and will be benefit to postoperative discharge of phlegm and rehabilitation.
