About a third of female infertility is caused by
tubal factors and endometriosis.
In some cases the tubal problem is
caused by pelvic inflammatory
disease, previous ectopic pregnancy,
obliterative fibrosis, tubal polyps, fibroids,
salpingitis isthmica nodosa ,fimbrial agglutination
or adhesions and hydrosalpinx.
However the most common reason
for tubal infertility is previous
tubal ligation for sterilization.
This could be at the proximal
(close to the uterus), midsegment
(mid-portion) or distal ( the last
third) of the tubes.
Tubal reversal is accomplished by tuboplasty.
Tuboplasty with the use of operating
microscope, loupes results in improved and
precise reapproximation and reanastomosis
of the tubal portions that are undamaged.
Microsurgical reanastomosis has been
successful in most cases with resulting
restoration of fertility in our experience.
In cases where the tubal occlusion is at
the tubocornual segment (the portion
of the tube closest to the uterus),
microsurgical tubocornual reanastomosis
is done.
At the midportion tubal isthmic-isthmic
reanastomosis is done with the greatest
success rate. Tubal isthmic-ampullary
reanastomosis, neosalpingostomy and
fimbrioplasty are performed for more
distant tubal occlusion or obstruction
cases.
Tomorrow we will look at most recent
data on this topic.
