~ LAVH ~
§ Classification of laparoscopic hysterectomy:
Type |
Procedure |
DL + VH |
Diagnostic laparoscopy prior to a vaginal hysterectomy,
to verify the absence of contraindications of vaginal hysterectomy. |
LAVH |
The laparoscopic component of the operation is
completed above the uterine vessels, which are subsequently secured by the
vaginal route. |
LH |
The uterine vessels are secured laparoscopically. |
TLH |
In addition to the uterine vessels, the uterosacral and
cardinal ligaments are secured laparoscopically and the cervix completely
freed from the vagina. |
ø DL: diagnostic
laparoscopy
ø VH: vaginal
hysterectomy
ø LAVH: laparoscopic-assisted
vaginal hysterectomy
ø LH: laparoscopic
hysterectomy
ø TLH: total
laparoscopic hysterectomy
ø Contraindications of
vaginal hysterectomy:
j Uterine size greater than
280 g
k Previous pelvic surgery
l History of PID
m Moderate or severe
endometriosis
n Concomitant adnexal mass
o Indication for
adnexectomy in nulliparity with lack of uterine descent
p limited vaginal access
(Vaginal hysterectomy is usually planned in women with mobile
uteri not greater than
280g, especially if there is some uterine descent.)
§ LAVH technique:
è Laparoscopic phase:
j Single-dose antibiotic for
prophylaxis
k Preparation and setting of
laparoscope
l Evaluate accurately the
pelvis and upper abdomen, and if possible, treat any pathological
findings.
m When ovaries are to be
conserved, use bipolar forceps and scissors to resect the round
ligaments , utero-ovarian ligaments, and fallopian tubes.
For adnexectomy, use bipolar forceps
and scissors to resect the round ligaments, infundibulo-pelvic
ligaments, mesosalpinx, and
mesoovarium.
n Opening of the bladder flap
è Vaginal phase:
j Circular incision of the
vagina
k Bladder dissection to the
laparoscopically-operned bladder flap
l Entry into the posterior
cul-de-sac
m Clamping, transecting, and
suture-ligating of uterosacral ligaments, base of cardinal
ligaments, and uterine vessels
n Peritoneal closure with
exteriorization of the pedicles
o Closure of the vaginal
vault, which is anchored to the uterosacral and cardinal ligaments
ø Securing the uterine
vessels is the most difficult and critical step of the procedure, and is
best performed during the vaginal phase.

§ Conclusion:
è When vaginal
hysterectomy is feasible, it is the first choice.
è LAVH may be used to
extend the applications of a vaginal route, particularly
in allowing safe utilization of a vaginal approach in
patients for whom VH
may be contraindicated according to conventional standards.
