2What is a Colposcope?
- Colposcope
- Stereoscopic, Binocular
- Microscope with 3 specifications
- low magnification (10 40)
- Focal length (20 25 CM)
- Width of visual field gt 25 MM.
- - NB Colpomicroscope (150 200)
3TEN COMMANDS TO BE A COLPOSCOPIST
- Gynecologist should be aware of
- 1. Value
- 2. Instruments.
- 3. Different terminology (Anatomical
histological Pathological Cytological and
Colposcopic) - 4. Indications.
- 5. Steps for colposcopy
- 6. Diagnostic Criteria. 7. Interpretation.
- 8. Pitfalls. 9.
Training. - 10. Treatment.
4Value of Colposcopy
- 1. Fill the gap bet. N/E Cytopathology.
- 2. Early detection for precancerous lesions of
lower genital tract (CIN, VAIN, VIN). - 3. Decrease diagnostic conization and
hysterectomy. - 4. Complementary for cytology or VIA (Each one
cover the disadvantages of the other). - CYTOLOGY DISCOVERS THE CRIME COLPOSCOPY LOCATES
THE CULPRIT.
5Instrument
1.Colposcope

- Stand (Easy movement).
- Accessories ( Gray filter Camera Electronic
flash ).
6 Instrument cont
2.Auxillary

Monsols sol .saline) - Cotton Buds-singleys forceps iris hook
7 Instrument cont..
III-extra auxillary

8TERMINOLOGY
Anatomical Terminology
- 1. Ectocervix ( vaginal surface of CX.).
- 2. Endocervix ( cervical canal).
- 3. Eversion (Dynamic process) may be true
(erosion) or false (ectropion).
9TERMINOLOGY cont..
Pathological terminology
- Metalplasia.
- Dysplasia (BET SQU. Epith CIS.) (Dediff.
disarrangement). - CIN (I, II, III).
- Micro invasive (lt 5mm no vascualr and lymphatic
extension). - Invasive carcinoma
- Hyper keratoses ( leukoplakia)
- Parakeratosis.
10HISTOLOGICAL TERMINOLOGY
- Epith. Covering
- Original epithelia . Squamous.
- .
Columnar - Metaplastic epithelia (Neonatal Period puberty
pregnancy). - Squamo Columnar J. (primary Secondary)
- Underlying Stroma.
11Cytological Terminology
-
- positive smear.
- negative smear.
- doubtful Smear.
-
-
- ( N/C Anisocytosis Hyperchromsia-Clumping).
Smear comment
Dyskaryotic cell
12Colposcopic Terminology
13(No Transcript)
14Transformation zone TZ
- Definition
- The area between the original squamocolumnar
junction caudally (which is now squamo
_Metaplastic junction) to the current (secondary)
squamo Metaplastic columnar junction cranially
(where islands of physiological Metaplastic
Epithelium is identified)
15Transformation zone TZ cont....
T Z can be altered by
- Age
- Pregnancy
- Oestrogen
- Menopause
16Indications
I) Diagnostic
- Abnormal pap, smear.VIAM
- Any suspicious lesion (CX Vagina vulva).
- In utero exposure to diethyl stilbestrol (or)
related drugs. - Infertility (?) cervical factor.
- Sexual assault victims.
- Cryocautery.
- Diathermy (loop).
- Laser.
II) Therapeutic
17Role of Colposcope
1. During Diagnosis
Localization of TZ
- Prove (or) disprove invasive cancer.
- Localization of the most ABN. Site for biopsy.
- Evaluation of extent (need for Conization).
18Role of Colposcope cont...
2. During therapy
- Suitability of the lesion for local destruction.
- Indications for conization
- No Colposcopic lesions (ve pap. Smear).
- Too extensive lesion.
- ECC Atypia.
- Micro invasion by Colposcopy Biopsy.
- Extensive CIN III but fertility is needed.
19Steps for Colposcopy
- History ( VIA - pap smear drugs infections
sexual.. etc) - Counseling explanation of the procedure to the
patient (psychic element). - Timing (8 12 day of the cycle).
- Position Examination table.
20Steps for Colposcopy cont..
- Exam.
- Inspection.
- Bimanual exam, (?!).
- Insertion of speculum (precautions).
- Cytology (spatula cytobrush CVE Cotton buds
or aspirator) - Colposcopy.
21Steps for Colposcopy cont..
A) Direct (saline)
- SQ. COL. J. endocervix vascular.
- Green filter.
- Use (Kogans speculum cotton bud singleys
forceps).
B) Amplified
- Acetic Acid 3 (3 4 min).
- Lugols iodine (?) (1 part I2 2KI 97H20).
C) Endo C.C. OR ECB (easier)
D) Colposcopic Guided Punch biopsy.
22Diagnostic criteria of Colposcopy
- Major (5)
- Vascular pattern.
- Intercapillary distance.
- Contour (surface pattern).
- Colour tone opacity.
- Borders (Dermarcation).
23Diagnostic criteria of Colposcopy cont..
Minor (5)
-
- Size (Extent).
- Keratosis.
- Aceto white areas.
- Iodine uptake.
- Cervical gland openings.
24Interpretation
25Interpretation cont
26Pitfalls of Colposcopy
- 1. False squamo- columnar j.(finger speculum
smear ). - 2. High squamo columnar J. in canal (gt 5mm up).
- 3. Previously treated cervix by cryo, or laser.
- 4. Adenocarcinoma in situ (difficult) -?
hysterocolpomicroscope. - 5. Subjective method (cervicography digital
color imaging Colposcopy (DCIC) are objective
methods.
27Lines of Treatment
- 1. No treatment.
- 2. Follow up.
- 3. Local destructive therapy (Electro
coagulation diathermy cryocautery cold
coagulation laser , photodynamic). - 4. Cone biopsy.
- 5. Hysterectomy.
28Criteria for local destructiveTherapy (LDT)
- 1. Satisfactory Colposcopy.
- 2. Expert colposcopist.
- 3. No suspicious of invasion (Cytology
Colposcopy Histopathology). - 4. ECC or ECB is negative.
- 5. Done by the expert colposcopist.
- 6. Good follow up.
29Recommendations
- Colposcopy is not a difficult procedure, but
without good training, maximum benefits are not
realized and serious mistakes can be made. - In modern practice, Colposcopy has become an
integral part of the gynecologic examination.
30Recommendationscont
- Colposcopy, can not be done in a vacuum, rather
it must be performed in combination with cytology
,VIA and tissue sampling. - Cervicography , digital colour imaging Colposcopy
(DCIC) computer aided colposcopy are objective
rather than subjective methods.
- Colposcopy, can not be done in vacuum, rather it
must be performed in combination with cytology
,VIA - Cervicography , digital colour imaging Colposcopy
(DCIC) computer aided colposcopy are objective
rather than subjective methods.
