No controlled studies of fertility Weber's review concluded that
there is no lessened fertility following cold-knife conization. Some studies
suggest incr. in preterm deliveries. Removal of cervical conn. tissue may
produce
weakness / inability to support full-term preg. Some have recommended
prophylactic cerclage after CKC, but studies do not show a benefit.
Spitzer M. J Lower Gen Tract Dis 1998; 4: 225.
Largest controlled retrospective study by Spitzer concluded laser
did not adversely affect fertility. Controlled studies examining pregnancy
outcome have not demonstrated an increase in preterm deliveries or pregnancy
complications.
Spitzer M. J Lower Gen Tract Dis 1998; 2:225.
Absence of a negative effect on fertility has been noted in several
controlled studies. Several controlled studies of pregnancy outcomes following
LEEP have failed to note any difference in gestational age, birth weight,
or cesarean deliveries. Spitzer M. J Lower Gen Tract Dis 1998; 2:

More smears obscured by blood when brush used (4.4%) compared to
spatula fast (0.6%) Adequacy of smears was equal between groups No endocervical
cells in 5.8% of brush-first group compared to 9.0% in spatula-fast group
(p = 0.7) More SIL in the spatula-fast group (l 1% vs. 7%) CONCLUSION:
quality of smear improved by using Ayre spatula first, followed by cytobrush.

36 patients evaluated with benzocaine spray or placebo spray before
colposcopy. Pain scores increased significantly after application
of either spray; benzocaine conferred no befit when used to decrease pain
or anxiety associated with colposcopy. Clifton PA. I Fam Pract 1998;
46: 242.
125 women received gel or placebo. Topical benzocaine gel was ineffective
in reducing discomfort reported on bx or ECC. Biopsy instrument sharpness
appeared critically important in level of pain. Discomfort with prior
Paps or pelvic exams, or hx of dysparunea assoc. with greater pain.

Randomized clinical trial of cryotherapy, laser vaporization, and
LEEP for CIN
No difference in complications, high success rates
Recurrence risk highest in women > 30 yrs, those with HPV types 16/18,
and those with prior dis.
CONCLUSION: No significant difference in the success rates for the
three treatments were seen in this population

608 women followed for three years 26% were HPV-positive at the
start
Increased risk of HPV was associated with incr. no. of vaginal sex
partners, younger age, high freq. of vaginal sex and alcohol consumption,
and increased lifetime partners for woman's partner
Average annual incidence of HPV was 14% About 60% infected sometime
during 3 yr period
Ho GYF. N Engl J Mod 1998; 338: 423.
A woman was likely to lose her HPV infection if it was newly acquired
31% resolved HPV in the first 6 mos, 39°/. in 2nd, and only 11%
in 3rd 6 mos
Adolescents and young women experience shortlived HPV infections, and
the manifestations (LGSIL) often undergo spontaneous resolution
CONCLUSION: conterv. mgmt for LGSIL/HPV
Ho GYF. N Engl J Mod 1998; 338: 423.
Infection with high-risk types and older age were risk factors for
persistent infection
Persistent HPV infection may in turn increase the risk of the development
and persistence of SIL
The association between persistent infection and multiple types of
HPV suggests women with deficient immune responses are more likely to develop
a persistent infection
Ho GYF. N Engl 1 Mod 1998; 338: 423.
Relation between SIL and certain types of continuous HPV infections
Some types of HPV produce multiple episodes of SIL
Either continuous or episodic HPV increases the chance of catching
SIL on periodic Pap smear

Pap smears of 7360 women evaluated
65% more diagnoses of HGSIL or greater abnormality seen with ThinPrep
compared to conventional smears
Greater number of adequate smears and fewer "adequate but limited by"
smears with the ThinPrep
Lee KR. Obstet Gynecol 199 90: 278.
ThinPrep identifies more histological dis. Individuals who read
slides for a living prefer ThinPrep over dry slides
The residual cells in the vial can serve as a source for HPV testing
, and in the future additional testing may be available as our technology
and understanding increase.
Cox JT. J Lower Gen Tract Dis 1999; 3(suppl 1): S8.
CLIA req. 10% rescreening of nl smears
Automation incr. possibility of detecting >10% of missed cases if sample
enriched
Using AutoPap increases 8X missed HGSIL
Cost is a consideration; automation incr. cost per case discov. from
$1000 for 100% or selected rescreening to >$3000

"The most difficult aspect of devising an optimum cervical cytological
screening service for women is ensuring that patients will not "fall through
the cracks" either in terms of notification of the abnomlal findings or
in terms of subsequent followup "
Cox TJ. J Lower Gen Tract Dis 1997; 1: 167.
"The most dangerous system is one in which the patient expects that
her Pap smear or biopsy results are normal if she has not been notified
otherwise."

Process by which the patient is assured of receiving notification
of an abnormal Pap

Several reports describe poor ECC sensitivity at detecting neoplasia
Positive ECC in woman with a satisfactory exam and normal-appearing
endocervical canal is likely to be a false-positive result
False+ ECC occurs when the endocervical curette "nicks" a lesion near
the external os Cox JT. J Lower Gen Tract Dis 1997; 1: 25 1 .
"In the presence of a satisfactory colposcopy and a visually normal
endocervical canal, data argue against performing routine ECC. Because
of cost-effectiveness, less patient discomfort, and a lesser chance of
subjecting women to unnecessary conization following false+ ECCs, the ASCCP
recommends that ECC not be performed when colposcopy is satisfactory."
Cox JT. J Lower Gen Tract Dis 1999; 1: 251.
ASCCP recommends either ECC on all patients or on selected individuals
For LGSIL on Pap, ECC can be performed selectively when colposcopy
unsatisfactory
For HGSIL on Pap, cone bx or electrosurgical loop excision is recommended
when colposcopy unsatisfactory
Cox JT. J Lower Gen Trod Dis 1997; 1: 251.
"Selective, rather than routine, endocervical evaluation by standard
ECC or brush should reduce the costs of colposcopy and biopsy by $24-$
100 per case for between 38°/.-81 of women evaluated. Savings should
be greater for younger populations where most colposcopy will be adequate."
Cox IT. J Lower Gen Tract Dis 1997; 1: 251.
High false-negative rate makes this a poor final arbiter in unsatisfactory
colposcopies Conization suggests ECC does not detect 50% of CIN III in
canal and 37% of cancer Cone bx is necessary to evaluate all CIN on Pap
with unsatisfactory colposcopy, and some argue ECC adds little to the work-up
Cox JT. J Lower Gen Tract Dis 1997; l: 251.
Prior therapy may cause "skip" lesions in the endocervical canal;
consider ECC for all patients with prior treatment to the cervix, even
if satisfactory colposcopic examination present Women with glandular atypia
or dysplasia on Pap smear also require ECC at colposcopy Novice colposcopists
should perform routine ECC until experienced in assessing the SO and 7Z
Cox JT. J Lower Gen Tract Dis 1997;1: 251.
Brush is rotated m the canal 180 degrees to limit bleeding and to
increase specimen adequacy
Alternately, brush can be gently rotated in the canal 5-10 turns with
light pressure against walls
Immediately following brush withdrawl, material is applied to the slide
and fixed
Alternately, brush can be cut from the shaft and placed in formalin
Cox Yr. J Lower Gen Toad Dis 1997; 1: 251.
Increased sensitivity of the brush may make it the preferred instrument
for endocervical sampling False+ from brush are likely from contamination
from passing over lesions at or near the cervical os Other brush false
positives from brush effect of cell distortion or cell clumping Many authors
suggest brush be the initial screen, followed by more specific ECC if brush
is positive
