CT scans lower risk of unnecessary appendix surgery

BOSTON (Reuters) - The chance of having an appendix removed unnecessarily has plummeted since 1996 in the United States, possibly because more doctors are using CT scans to confirm appendicitis diagnoses, researchers said on Wednesday.

The likelihood of an unnecessary appendectomy went from 24 percent in 1996 down to 3 percent in 2006, according to a team led by Dr. Steven Raman at the University of California, Los Angeles.

Their survey of 1,081 people who had had an appendix removed, showed the use of CT scans to check for suspected appendicitis went from 20 percent in 1996 to 85 percent 10 years later.

About 8 percent of the population develops appendicitis at some point in their lives as the finger-like sac at the start of the large intestine becomes enlarged and inflamed.

If the sac bursts, it can be fatal. Doctors have historically erred on the side of surgery when it looked like a patient with abdominal pain might have appendicitis.

The results appear in a letter to the New England Journal of Medicine.
波士顿（路透社）-研究人员在周三指出，自从1996年以来，美国非必须的阑尾切除几率已经直线下降，这可能是因为更多的医生使用CT扫描来确认阑尾炎诊断。

根据洛杉矶加利福尼亚大学的Dr. Steven Raman带头的组队可知，非必须的阑尾切除术可能性已经从1996年的24％降至2006年的3％.

他们观察了1,081名阑尾切除的人，显示可以阑尾炎使用CT扫描检查的从1996年的20％升值10年后的85％.

大约8％的人们在他们人生的某一阶段发生阑尾炎，表现为大肠起始处的指状囊扩大并发炎。

如果发生穿孔则可能是致命的。当一个腹痛患者看起来可能像是阑尾炎时，医生往往经验性的错误选择手术。

这一结果是在给《新英格兰医学杂志》的一封信上出现的。


  CT确实能够减少误诊率，但就我国来说肯定应用不起来,现在到处在限制医药费,到处在打击阑尾炎,因为在一些人的眼中,阑尾炎就是一个小手术,它的价值就是只要几百元就可以医治好出院.
