The method of Fine-needle Aspiration Tissues is easy, safety, quickly, and sensitivity is good, and diagnosis rate is high, and credibility is strong, and to patient It is close to non-invasive, one of important diagnostic method having become clinical disease.
Cytodiagnosis maximum is advantageous in that can be with morphologic basis early discovery and diagnosing tumour, its operation and diagnostic method Easy, safe, directly perceived, any other preoperative planning hardly matches at present, and needle absorbing mainly has the advantage that
The most typically it is not required to special installation, it is easy to carry out at medical departments at different levels.
2. fine needle aspiration is close to body not damaged, and cicatrix is not left in local, and hemorrhage infection chance is the fewest, and patient's misery is little, easily In being accepted by patient.To Deep Lesions and nerve, euangiotic critical position, FNAC has more preferable safety and can Row.
3. smear cells is fresh, is not likely to produce degeneration and autolysis;Cell is not susceptible to artificially extrude equivalent damage, morphosis Clearly, beneficially accurately identifying and Differential Diagnosis under mirror.Diagnosis for more typical cytology's case is quick, usual patient Its diagnostic result of immediate delivery.
4., for some the most negative or suspicious diagnosis, can immediately repeat to draw materials inspection with multiple location, and be easy to examining, dynamically Observe and observation of curative effect.
5. the good pernicious diagnosis rate of pair pathological changes is high.Have and may be up to compared with the usual diagnosis rate of clinical cytology diagnostician of rich experiences More than 95%, lesion type diagnosis rate is up to more than 80%.
6. applied range, is suitable for almost any site morbidity of body.By images such as x-ray, B ultrasonic, CT and MRI Learn under orientation direction, Puncture cytology diagnosis can be carried out by deep organ each to health tissue.
7. aspirate is living tissue, can be used for other biological experiment, cell cultivation, immunology and molecular biology etc. and checks.
8. complement one another with diagnostic methods such as histopathologic examinations.
9. some pathological changes such as galactocele, retention cyst of salivary gland etc., puncture up to therapeutical effect.
Great mass of data shows, although FNAC has many advantages, but still has minority case to be likely to occur mistaken diagnosis, and usual false negative is big In false positive.Main cause and pathological changes draw materials that satisfaction, film-making be the most proper and the diagnostic level of cytology worker etc. closely Relevant.
Owing to tissue mass and the cell component thereof of fine needle aspiration are less, tissue morphology in specimen and intercellular substance structure major part or Completely lose, thus the overall picture of lesion type can not be reflected;Specific diagnosis and analysis to cancer growth tissue, it is judged that transfer The tissue-derived case having of stove remains limitation.
Clinical cytology is a kind of diagnostic rather than screening property technology, in place of having its valuable advantage and some limitation.In order to carry The accuracy rate of high cytodiagnosis, it is necessary to get hold of the link of three aspects: 1. perfect and puncture technique and have diagnosis accurately It is worth the acquisition of cytologic specimen;2. the smear of high-quality and Color;What 3. close combination with clinical data carried out smear is accurate Analyze.Meanwhile, not only emphasize clinicist to the interest of clinical cytology and confidence, self of cytodiagnosis person to be paid attention to The renewal of knowledge, diagnostic experiences of enriching constantly.
How current research and development institution both domestic and external improves the ability of syringe needle adherent cell mostly in research, but if lacks necessity Vacuum suction, then for puncture suction tuberosity, the hardest and tuberosity of shortage blood supply, its cell is difficult to all the time Effectively adsorbed, it is impossible to improve diagnosis rate.Unfortunately, there is no and suitably there is the collection of vacuum suction function set The standby difficulty that can reduce one man operation.
The method of Fine-needle Aspiration Tissues is easy, safety, quickly, and sensitivity is good, and diagnosis rate is high, and credibility is strong, and to patient Being close to non-invasive, one of important diagnostic method having become clinical disease, potential applicability in clinical practice is wide.But also deposit simultaneously In certain limitation.In above-mentioned limitation, pathological changes satisfaction of drawing materials is closely bound up with clinicist.If faced Bed doctor is capable of perfect and puncture technique and have the acquisition of diagnostic value cytologic specimen accurately in operation, that The limitation of Fine-needle Aspiration Tissues will be more and more less, and potential applicability in clinical practice will be more wide.And want to carry in this respect Height, then must say from operation itself.
In the operating process of Fine-needle Aspiration Cytology, patient's right hand is held pin and is punctured into tuberosity through skin rapidly, when needle point is worn When thorn is to swollen thing centre, having two kinds of modes of operation at present: one, when two people operate, assistant's auxiliary retracts pintle, cause 3~ About 4ml negative pressure.After puncture needle is aspirated 5~10 times in tuberosity by puncture person repeatedly, extract puncture needle.Two, one man operation Time, patient's pintle to be retracted, causes 3~about 4ml negative pressure, is repeatedly aspirated 5~10 times by puncture needle again in tuberosity After, extract puncture needle.The advantage of two people's operations is that patient only need to be carried out by puncture needle in tuberosity, repeatedly aspirates 5~10 times Accurate operation, and complete retracting pintle and causing the extensive operation of 3~about 4ml negative pressure to give assistant, so that patient avoids Carry out self-contradictory action on hand same, reduce the generation of various danger, be conducive to concentrating one's energy target is carried out accurately Aspiration biopsy.Shortcoming is that the cooperation of patient and assistant is required high by two people's operations, if both sides lack accurate synchronicity, that The probability that various danger occur can significantly raise on the contrary, and therefore two people's operations have feasibility, but are unfavorable for technique Carry out on a large scale.The advantage of one man operation is that patient coordinates without other people, and operation has high synchronicity, has been advantageously implemented Beautiful and puncture technique and have the acquisition of diagnostic value cytologic specimen accurately, farthest avoids the generation of various danger. Shortcoming is the extensive action that patient should complete to retract pintle generation negative pressure on the other hand, completes again repeatedly to take out puncture needle in tuberosity Inhale fine movement for several times, this belong to self-contradictory action in essence, it is desirable to patient has extremely strong coordination of body Property, and major part clinicist is obviously difficult to skillfully grasp, this is easy for causing various dangerous generation, and reduces aspiration biopsy Success rate and accuracy rate.Therefore one man operation is most beneficial for realizing perfect and puncture technique and have diagnostic value thin accurately Born of the same parents learn the acquisition of specimen, at utmost avoid the various dangerous operational approach occurred, but for current equipment, are only suitable for In the clinicist that body harmony is extremely strong, owing to major part clinicist is difficult to skillfully master a skill main points, therefore it is difficult to benefit Popular.Research and development are objectively needed to be suitable for one man operation's cellular collector.
