※ 引述《Aeolux (艾歐)》之銘言：
: 血便的定義應該要肉眼可見才比較對吧，跟左側相比，右側大腸癌多為便中潛血反應陽性
: 而少肉眼可見的血便吧...
: 一樣是這種要附什麼資料啊...
: 建議答案: C D
Sabiston Textbook of Surgery, 18th ed
NEOPLASIA
Cancers in the right colon more often present with melena, fatigue associated
with anemia, or, if the tumor is advanced, abdominal pain. Although
obstructive symptoms are more commonly associated with cancers of the left
colon, any advanced colorectal cancer can cause a change in bowel habits and
intestinal obstruction
本題幹未聲明是否與left colon cancer之比較，所以
若腹痛也是右側大腸癌的症狀的話，依照Sabiston的說法，是在advanced tumor的
前提之下方成立；同理若在advanced colorectal cancer前提下，
，intestinal obstruction(小腸阻塞也是腸阻塞的一種)也是會發生的
建議答案：無答案，全部送分
