BACKGROUND Few randomised controlled trials have sufficient power to show clear advantages of different designs of cervical-smear collection devices. We studied by systematic review whether the design of cervical-smear devices affects rates of inadequate smears and detection of disease and whether the presence of endocervical cells in the smear affects detection of disease. METHODS We sought relevant randomised controlled trials by computer literature review by MEDLINE backed up by a manual… Expand

Paper Mentions

Observational Clinical Trial
A clinical study to determine the adequacy and efficacy of the InPath e2TM Collector compared to the FDA-approved spatula/cytobrush when used as the cell collection device in screening… Expand
ConditionsBiopsy, Colposcopy
InterventionDevice
Observational Clinical Trial
A study which assesses the physician's comfort level and satisfaction when using the e2TM Collector compared to the Spatula/SytoBrush technique.  
ConditionsCervical Cell Collection
InterventionDevice
Optimal collection technique and devices for a quality pap smear.
TLDR
The combination of the Cytobrush (endocervix) and spatula (ectocervIX) is superior for a quality Pap smear and the broom alone performs poorly, while the sequence of collection was not important in conventional Pap smears. Expand
Systematic Review, Meta-Analysis and Randomized Controlled Trials in Cytopathology
TLDR
SR, MA and RCTs are less frequently utilized in pathology than in clinical medicine, and Cytopathologists should be more aware of the benefits of SR and MA in resolving uncertainties and improving the clinical applicability of level III diagnostic studies. Expand
Satisfactory sampling in cytological cervical diagnosis: comparison between a conventional and a new sampling device.
TLDR
Cervical smears performed by PapCone® were adequate and generally easier to screen than conventionally performed ones. Expand
Evaluation of national guidelines and implementation of new techniques with the Dutch screening program against cancer of the uterine cervix
TLDR
It is concluded that the true prevalence of squamous lesions in women with a recent ECCsmears is significantly lower as compared to ECC+ smears, lending support to the decision to abolish the repeat of ECC smears in the Dutch population screening programme. Expand
Liquid-based cytology in cervical screening: a rapid and systematic review.
TLDR
There is some evidence that liquid-based cytological methods offer the following advantages over traditional smear techniques: a reduction in the proportion of inadequate specimens and an improvement in sensitivity and/or specificity, and a possible reduction in specimen interpretation times. Expand
CAN THE USE OF AYER'S SPATULA AND CYTOBRUSH IN COMBINATION, IMPROVE THE ADEQUACY OF CERVICAL SMEARS.
TLDR
The combination of Ayer’s spatula and Cytobrush is used in combination to improve the adequacy of smears as it is most efficient in sampling the endocevical cells. Expand
Comparison of the efficacy of the cervex brush and the extended-tip wooden spatula with conventional cytology: A longitudinal study
TLDR
Using the Cervex brush with conventional cytology significantly decreases inadequate smears and increases TZ sampling when compared to the extended-tip spatula and can offer improved cervical screening in countries unable or unwilling to convert to LBC. Expand
Impact of introduction of endocervical brush on cytologic detection of cervical epithelial cell abnormalities: A clinical audit of 13-years' experience at a cancer research centre.
TLDR
Cervical sampling using combined spatula and endocervical brush reduces the unsatisfactory rate and improves the detection of both squamous and glandular precancerous lesions. Expand
Comparison of Papanicolaou Smear Quality with the Anatomical Spatula and the Cytobrush–Spatula: A Single-Blind Clinical Trial
TLDR
The anatomical spatula can be used as a single device in conventional cytology in place of the cytobrush–spatula with the aim of improving the quality of smears without necessarily increasing the cost. Expand
The Frequency of Unsatisfactory Pap Smears Based on the Bethesda System-2001 and their Reasons
TLDR
It was shown that sampling by trained personnel, persistent supervision and use of appropriate equipment can reduce unsatisfactory Pap smears. Expand

Relation between sampling device and detection of abnormality in cervical smears: a meta-analysis of randomised and quasi-randomised studies
TLDR
These results support the use of either the extended tip spatula, a combination of any spatula plus the Cytobrush or cotton swab, or the Cervex brush for cervical screening. Expand
A randomized control trial of two cervical spatulas
TLDR
It is concluded that the Rocket spatula offered no advantage when used in these circumstances and illustrates how spurious conclusions of sampling efficacy can be drawn if only one type of indicator cell is used as an endpoint. Expand
Cervical cytology: a randomized comparison of four sampling methods.
TLDR
The cotton swab-spatula and Cytobrush- Spatula appear to be the most effective screening methods for nonpregnant and pregnant patients, respectively. Expand
Detection Of Abnormal Cervical Smears: A Comparative Study
TLDR
It is concluded that the Multispatula produces a better quality smear which results in a decreased false negative rate in comparison with the Ayres Spatula. Expand
Does feedback improve the quality of cervical smears? A randomized controlled trial.
TLDR
It is suggested that monthly feedback with peer comparison may have a positive relationship with some aspects of quality improvement in cervical screening. Expand
Which cervical sampler? A comparison of four methods
TLDR
Four cytology sampling methods were compared in 1063 patients referred for colposcopy with a recent abnormal smear and the suggestion of advantage for the Aylesbury spatula merits further investigation. Expand
Adequacy of cervical cytology sampling with the Cervex brush and the Aylesbury spatula: a population based randomised controlled trial
TLDR
The Cervex brush offers no advantage over the Aylesbury spatula in reducing rates of inadequate smears when used in primary care, and group randomisation is useful when evaluating community based interventions but requires modified statistical techniques. Expand
A Randomized Trial of Three Methods of Obtaining Papanicolaou Smears
TLDR
Use of a spatula plus endocervical brush in nonpregnant women because the rate of pathology detected is not lower than for the swab, the brush may detect adenocarcinoma better, and the Brush may avoid the necessity of repeating smears in which endocovical cells are absent. Expand
A Randomized Clinical Trial Comparing the Cytobrush and Cotton Swab for Papanicolaou Smears
TLDR
The Cytobrush/ Spatula is superior to the cotton swab/spatula in obtaining endocervical cells and application of the Bethesda System results in a significant number of less-than-optimal smears. Expand
Comparison of four cytologic sampling techniques in a large family planning center.
TLDR
It appears that in a young population, the instruments used for cervical sampling are not likely to significantly influence the detection of dysplasia if skilled personnel take the smears. Expand
