Diagnostic
hysteroscopy
For
hysteroscopy, a very narrow telescope is inserted into
the uterus (womb) via the vagina and cervix. Carbon
dioxide gas or a liquid such as saline is usded to
distend the uterine cavity to give a clear view. The
image can be projected on to a television screen using
a small video camera.
Hysteroscopy
allows examination of the endometrium (lining of the
uterus), tubal ostia (small channels on either side
which lead to the fallopian tubes), and assess the
shape and size of the uterine cavity. Abnormal findings
include polyps, fibroids, adhesions (scar tissue),
septa (a midline division), or simply that the endometrium
is unusually thickened. A biopsy is often taken at
end of the investigation to check the endometrium.
Diagnostic
hysteroscopy does not take a long time and is not
particularly uncomfortable. At the Royal Free,
it is usually done as an out-patient procedure.
