Large intestine the pathology of cancerous sex intestinal obstruction

Bowel expands: Colon is the bacterium breeds in great quantities, ferment the aeriform quantity of generation increases significantly, cause deglutition gas quantity to also increase sorely, gastric bowel exudate absorbs an obstacle, emit into colon ceaselessly through answering blind valve. Obstruction carries colon to undertake the gender expands nearly, celiac pressing is elevatory, lie between move on flesh, occurrence loop breathes functional obstacle.

Large intestine the pathology physiology of cancerous sex intestinal obstruction changes

(1) bowel expands: Colon is the bacterium breeds in great quantities, ferment the aeriform quantity of generation increases significantly, cause deglutition gas quantity to also increase sorely, gastric bowel exudate absorbs an obstacle, emit into colon ceaselessly through answering blind valve. Obstruction carries colon to undertake the gender expands nearly, celiac pressing is elevatory, lie between move on flesh, occurrence loop breathes functional obstacle.

(2) is humoral and missing: The block of any reasons all can appear liquid quantity loses a phenomenon. Appear in alvine canal especially wring narrow when, a large number of liquids are missing, serious dehydrate, blood condenses, hematic capacity drops, bring about shock.

(3) electrolyte is disorder: The alvine exudate with the many block of large intestine, serous or blood is missing, inevitably companion has electrolyte to lose, soda acid balance is maladjusted, bring about serious electrolyte disorder.

(4) infection and poisonous blood disease: As the ceaseless development of obstruction, alvine wall attenuates, the gender increases or punch a large number of fine mattress and toxin enter peritoneal antrum fully, cause serious bacterial sex peritonitis and poisonous blood disease, bring about shock of the noxiousness in infection, exhaustion of much viscera function dies even.

2. The pathology characteristic of cancer of obstruction sex colon

(1) large intestine 70 ％ are located in cancerous sex block left half colon, right half knot intestinal obstruction occupies large intestine only the 30 ％ of 20 ％ ～ of cancerous sex block, among them of 30 ％ left half knot intestinal obstruction is located in colonic liver area.

(The research of 2) pathology makes clear, cancer of sex of 54 ％ block is infiltration cancer, the Zhou Sheng that show annulus is long, have very remarkable fibre reaction; Cancer of sex of 60 ％ block belongs to DukesC and D period.
