The diagnosis method of large intestine cancer and rectum cancer

A, rectum ass pick up
The anus points a check to in brief and easily go, the rectum points checks to is still the rectum cancer surgical operation ex- series of check currently in the most basic with the most important check method.
Two, the laboratory check
1)move bowels concealed blood to experiment:This method is simple to easily go, is early large intestine cancer census Shai method and colon paroxysm of normal regulations check.The one who have condition can also apply an immunology method to raise a correctness.
2)the hemoglobin check:Any reason is unidentified and anemic, the hemoglobin is lower than a 100 gsthe L should suggest to make a barium to infuse bowel check or the fiber colon mirror check.
3)the serum cancer Pei antigen(CEA) check:The CEA check doesn't have the diagnosis value of particularity, therefore isn't suitable for is a census or diagnose in early days, but prepare behind and inspect curative effect and relapse a square mask to contain certain help to the estimate.
Three, inside the mirror check
Any has then blood or the bowels to be used to a change, through the rectum point check just like often finder, carry on B-like in shape colon mirror or the fiber colon mirror check in response to the normal regulations.Inside mirror check can at orthoptic under observation focus circumstance, and can take to live check to make pathology diagnosis.
Fiber colon mirror check currently but speech is to the pathological changes inside the large intestine diagnose most effectively, the most safe and the most dependable check method, overwhelming majority in early days large intestine cancer can from inside mirror check detection.
Four, the dual contrast build a shadow
Traditional barium the detection rate of large intestine cancer and small gland lump that infuse the bowel X line's check to the earlier period and diagnose an accurate soldier, have become the emanation section normal regulations check currently.
Five, the CT diagnose
The CT doesn't can do the method that diagnoses for the earlier period, but the CT has important meaning to the cent period of colon cancer, particularly for estimate ability not direct surgical operation, but at apply an outside emanation or put to treat inside the partial chamber after probably drive surgical operation cut off of the patient is of great value.CT to the rectum cancer in later period and relapse the surgical operation estimate of sex rectum cancer has already compared the gist righteousness, can directly observe the tumor infringes upon a pelvis muscle(lift an anus muscle and shut a muscle inside the bore, the tail bone muscle, pear-like in shape muscle and hip muscle) urine bladder and prostate gland.
After operation 3 can make a chamber CT check in month, as a foundation slice, in order to in with check against to use while visiting.After operation the 2~3 years internal help separates to make a CT check once in 6~8 months each time, or when CEA goes up reexamination CT.In addition, the CT provide a correct fixed position towards relapsing sex rectum cancer application to put to treat canning, and the Ba physical volume of assurance adequacy.
Six, the super voice show an elephant check
Super voice inside the rectum showing the elephant check is with probe into a rectum cancer to outside invade and tumor to rectum wall of gradually degree for a kind of new diagnosis method of purpose, in 1983 since start being more applied than clinical.Super voice inside the rectum show an elephant check can with accuracy diagnose a tumor infringe upon of part and size.
Seven, the Ci resonance check
The outside that the researcher calls to the rectum cancer invades, Ci resonance check(MRI) more the CT is more meaningful.But the Ci resonance still hasn't a few technique problem demands currently perfect, also need to deepen further to the portrait understanding that the Ci resonance provides, shows elephant with super voice inside the chamber to compare in the meantime, the Ci resonance check expenses is expensive to is also the obstacle that it extensively applies.
