腹腔游离气体在急腹症超声诊断中的价值

目的：结合临床资料，探讨腹腔游离气体的超声诊断价值。方法：回顾分析108例超声显示腹腔游离气体，结合临床病史及其它超声表现，提示诊断相应疾病的患者，与X线检查结果对比，均经手术及临床结果证实，评价腹腔内游离气体对提示超声诊断的价值。结果：108例患者中，超声提示上消化道穿孔89例，其中X线诊断80例，符合率90％（80／89），手术证实84例，符合率为94％（84189），超声假阳性率为6％（5／89）；超声提示急性胰腺炎10例，其中X线诊断8例，符合率80％（8／10），手术证实9例，符合率为90％（9／10），超声假阳性率为10％（9110）；超声提示急性原发性腹膜炎6倒，其中X线诊断5例，符合率83％（5／6），4例手术证实，符合卒为67％（4／6），超声假阳性率为33％（216）；超声提示缺血坏死性肠炎3例，其中X线诊断2例，符合率67％（2／3），手术证实3例，符合率100％（313）。结论：超声可敏感的发现腹腔游离气体，结合相应超声征象，对提示急腹症的超声诊断有较高应用价值。

Ultrasound Diagnosis Value of the Floating Gas in Peritoneal Cavity on Acute Abdominal Pain

Objective Combination of climcal data to study on the ultrasound diagnosis value of the floating gas in peritoneal cavity. Methods To review and analysis of the 108 patients ultrasound diagnosis showed the floating gas in peritoneal cavity, With clinical medical history and other ultrasound design, hints corresponding disease, and the x-ray examination by contrast, surgery and clinical results confirmed. Evaluate tile value of the floating gas in peritoneal cavity on definite ultrasound diagnosis. Result A total of 108 patients, ultxasound hints on Gastroin- testinal perforation 89 patients, and X-ray diagnosis 80 patients, positively diagnosed with the positive value of 90% （80/89）, 84 patients were verified by operation, positively diagnosed with the positive value of 94% （84/89）, 5 patients were pseudo-positive with the pseudo-positive value of 6% （5/89）. Ultrasound hints on Acute pancreatitis 10 patients, and X-ray diagnosis 8 patients, positively diagnosed with the positive value of 80% （8/10）, 9 patients were verified by operation, positively diagnosed with the positive value of 90% （9/10）, 1 patients were pseudo- positive with the pseudo-positive value of 10% （1/10）. Ultrasound hints on acute primary peritonitis 6 patients, and X-ray diagnosis 5 pa- tients, positively diagnosed with the positive value of 83% （5/6）, 4 patients were verified by operation, positively diagnosed with the positive vable of 67% （4/6）, 2 patients were pseudo-positive with the psando-positive value of 33% （2/6）. Ultrasound hints on ischemic necrosis en- teritis 3 patients, and X-ray diagnosis 2 patients, positively diagnosed with the positive value of 67% （2/3）, 3 patients were verified by operation, positively diagnosed with the positive value of 100% （3/3）. Conclusion The floating gas in peritoneal cavity cml be sensitively found by uhrasound, combined with others corresponding ultrasound designs, have a high value on diagnosis acute abdominal pain.
