(1)The rectum means that it is easy to examine, find the critical inspection method of rectal cancer in early days, but is often ignored. Generally can find from the intersection of rectum and the intersection of rectum and swollen thing within the 7- 8cm, advise patients, hold one's breath, increase the belly, pigeonhole, can reach higher position. Seeing that 60%- 75% of the large intestine cancer patients in our country are rectal cancer, and sections of rectum the intersection of tumour and bottom flange from the intersection of rectum and 7- 8cm under 75% more than tumour lie in the the intersection of rectal cancer and patient, so most rectal cancer can mean examining and checking, finding through the rectum. All meet patients symptom of having having blood in one's stool, rectum that stimulates symptom, stool to be out of shape etc. should mean examining the rectum, movements should be soft while checking, must guard against rudely, should notice whether there are swollen things that are touched, swollen thing from the intersection of rectum and distance and size, hardness, the intersection of activity and degree, mucous membrane smooth, has tenderness and with the relation around, organize before infringing the sacral bone, if the wall before tumour lay, men must define the relation with prostate, women patient need, make vagina, mean, examine still, find out, infringe wall behind the vagina. Mean that examining should observe and have bloodstains to point set to check-off. It is in order to be chosen the most basic, most important inspection method that the operation way of rectal cancer can't be omitted too that the simple rectum means examining.
(2)The inner mirror checks and includes the proctoscope, second form colon mirror, mirror in supersound inner mirror, three-dimensional rectum supersound in of rectum.
The proctoscope is checked " One section of cancers under rectum " The most convenient, do not need the intestine to plan, can observe the position of tumour, infringe the range, tumour reason and distance of the anus reason, and can do living subjects and organize the inspection and confirm the type of tumour. As to one section of cancers under rectum, need pathology to implement the perineum of belly and jointly radically treat the skill after making a definite diagnosis of.
Second the intersection of form and the intersection of colon and mirror can check from all rectum and part second form colon within the the intersection of rectum and 25cm, only need to clean and play a section of large intestine, can find more than 60%- 70% of the large intestine cancer patients.
The mirror can understand to check tumour infringes the depth and infringes the surrounding tissue situation in supersound in the rectum,
The mirror is checked not only has improved the ultrasonic rate of accuracy in two-dimentional in the three-dimensional rectum supersound, and can find out about the infringement situation of tumour about the patient obstructing.
The above-mentioned inner mirror is checked, not only observe pathological change directly but also pick the living subject to organize doing pathological diagnosis (fetch alive and examine) at the same time . It needs to pay attention to drawing materials in the position while examining alive to fetch, click and draw materials more. If live and examine negatively and clinical manifestation is cancer patients of large intestine, should draw materials so as not to leak and examine repeatedly. It is more serious to leak and examine the evil consequence caused.
(3)X-ray the intersection of barium and enema check barium pharmaceutical the intersection of enema and diagnosis in rectal cancer help strong, so not classify as routine inspection, only in order to get rid of the application at the time of multiple tumour of the rectum. At present, must rely on cases made diagnosis of barium enema not to be many, so has already seldom employed.
