Perforation of the digestive tract ultrasonography and X -ray examination in the diagnosis

The results can not exclude the diagnosis of gastrointestinal injury ,[link widoczny dla zalogowanych], can be false negative . Ultrasound on the gas and liquid sensitive to trace of free gas (about 2mL) and a small amount of ascites (about 20mL) to be sensitive to show that the diagnosis of gastrointestinal perforation opened up a new inspection approach iSl. Although ultrasound can not directly damage the gastrointestinal tract exploration and injury site, but can be intra-abdominal fluid after injury , product gas and other indirect signs for diagnosis. Ultrasonography for diagnosis of gastrointestinal injury has the following advantages [ 61: (1 ) can accurately display the location of fluid and fluid depth can be measured , estimated fluid volume ; (2 ) can be found in any free intraperitoneal gas Exist. Xiece position, the liver and spleen and the diaphragm can be seen between the hyperechoic gas ; flat supine position the abdominal wall in the abdominal free gas under the visible reflection stripe ; by first filling the lower abdomen low enough high bladder 14,9 . Chinese doctors CHINAMODERNDOCTOR signs in front of free gas can be found ; ( 3 ) intra-abdominal exploration and bowel can be uneven around the mass echo. Ultrasound detection of free intraperitoneal gas was low, this group was 76.09% , as x -ray examination . x ray not suggest a small amount of effusion or limitation of abdominal mass ,[link widoczny dla zalogowanych], and ultrasound can show whether abnormal visual mass,[link widoczny dla zalogowanych], ascites , etc. , can make up for lack of x ray . Gastrointestinal injury ,[link widoczny dla zalogowanych], omental transfer , the formation of a clear boundary within the package was non-uniform strong echo , ultrasound can be inferred about the damage location . Ultrasound can detect substantial organ damage and complications . In short, both ultrasound and x -ray examination with a comprehensive analysis of clinical acute abdomen to provide fast and reliable diagnosis. 【
