    大腸鏡檢查
  • BFecal occult blood test
    糞便潛血試驗
  • CBarium enema
    鋇劑灌腸
  • DDigital rectal exam
    肛門指診
Explanation · 中文詳解

大腸鏡檢查(Colonoscopy)被公認為大腸直腸癌篩檢的黃金標準,因為它不僅能直視檢查整個結腸,還具備切除息肉的治療功能。糞便潛血檢查僅能作為初篩,無法確診病灶位置或進行組織切片。鋇劑灌腸屬較舊的檢查,無法直接切除息肉。

Colonoscopy is the gold standard for colorectal cancer screening because it allows for direct visualization of the entire colon and enables the removal of polyps or biopsy of suspicious lesions. Other methods like fecal occult blood testing or barium enemas are less sensitive and cannot provide definitive diagnosis or therapeutic intervention.

✦ 台美臨床差異

美國與台灣對於 50 歲起的大腸鏡篩檢普及度皆高;差異在於美國對篩檢間隔的彈性,台灣則積極推廣健保給付的糞便潛血。
