Abstract
Pap smear is a screening procedure to detect precancerous lesions to
prevent subsequent invasive cervical cancer. Manual Liquid Based Cytology (MLBC)
has been developed as an alternative to Conventional Pap Smear (CPS) as it is said to
increase the rate of detection of precancerous lesions as it reduces the screening time,
the artefacts, giving a clean background on the smear. In this study, cervical screening
was performed in all married women of reproductive age group who visited
Department of Obstetrics and Gynaecology over a period of one year from February
2017 to January 2018. Out of which 350 cases were randomly selected for comparison
between CPS and MLBC. Slides were examined for cytomorphological parameters.
CPS showed higher percentage of inflammatory lesion 80% as compared to MLBC
with 46.1%, Unsatisfactory smear in CPS was 10% and in MLBC was 49%, Normal
smear was reported in 07% cases in CPS and 3.15% in MLBC. Most common cause of
unsatisfactory smear in CPS is obscuration by blood and inflammation whereas that in
MLBC was scant cellularity. The cellular features are better in MLBC as compared to
CPS and also background is more clear in MLBC as there was no obscuration by
RBCs or inflammatory cells while in CPS, the background is dirty due to the presence
of RBCs, necrosis and inflammation
