Vaginal Hysterectomy


Simple Vaginal Hysterectomy

When hysterectomy is indicated, the most appropriate route of removal of the uterus must be chosen. Hysterectomy can be performed transvaginally, abdominally, laparoscopically, robotically, or with laparoscopic or robotic assistance. The decision to proceed with a vaginal hysterectomy depends on numerous factors. These include the surgeon’s training and comfort level with the procedure, the size and mobility of the uterus, the presence of pelvic relaxation, and the benign or malignant nature of the condition. In general, vaginal hysterectomy is less morbid and results in a quicker recovery time than abdominal or laparoscopy-assisted approach. In contrast to abdominal or laparoscopic hysterectomy, vaginal hysterectomy is limited by the size and particularly the mobility of the uterus and by the capacity and elasticity of the vagina. Both are relative criteria because a large uterus can be morcellated, and a narrow vagina can be enlarged with an episiotomy. More training in the technique of vaginal hysterectomy is necessary because at present it is the least frequent route of hysterectomy in the United States.

Vaginal hysterectomy begins with appropriate positioning of the patient. Vaginal hysterectomy is performed with the patient in the dorsal lithotomy position with her feet in “candy-cane” or “Allen” stirrups. The patient’s buttocks should extend slightly over the edge of the table so that a posterior retractor can be placed easily. The thighs are somewhat abducted, and the hips flexed ( Fig. 51.1 ). Excessive flexion and abduction of the thighs should be avoided because this can lead to position-induced nerve injuries. The lateral aspects of the legs should be clear of the stirrups to avoid pressure on the peroneal nerve. The urinary bladder is then emptied with a catheter, and the vaginal area is prepped in a normal fashion. Examination under anesthesia is performed to confirm the degree of uterine descensus, width of the vaginal outlet, and presence or absence of pelvic disease.

Surgical Technique

  • 1.

    With a speculum depressing the posterior vaginal wall, the anterior vaginal wall is lifted with a Deaver or Heaney retractor. The cervix is grasped with two single-toothed tenacula, and downward traction is placed on the cervix.

    • Vasoconstrictors such as vasopressin (Pitressin), phenylephrine (Neo-Synephrine), or epinephrine may be injected into the paracervical tissue if no medical condition, such as hypertension or heart disease, contraindicates their use. We prefer to use a prepared solution of 1% or 2% lidocaine or 0.5% bupivacaine with 1:200,000 epinephrine. Use of these ready-made solutions negates the need for mixing in the operating suite and provides some preemptive analgesic at the surgical site. The surgeon should remember that the maximum amount of lidocaine with epinephrine used should not exceed 7 mg/kg or 500 mg total in the healthy adult, whereas the amount of bupivacaine with epinephrine generally should not exceed 225 mg. The total dosage for vaginal hysterectomy is usually 5 to 10 mL of injection. Should a medical contraindication to the use of vasopressors be present, injectable saline provides the benefits of hydrodistention without the cardiovascular risks.

    • A knife or electrosurgical instrument is used to make the initial incision through the vaginal mucosa ( Fig. 51.2 ). The position and depth of this incision are important because they determine access to appropriate planes that will lead to the anterior and posterior cul-de-sacs. The appropriate location of the incision is at the site of the bladder reflection, which is indicated by a crease formed in the vaginal mucosa when the cervix is pushed slightly inward. If this location cannot be identified, one should make the incision low rather than high to avoid potential bladder injury. A circumferential cervical incision is accomplished ( Fig. 51.3 ). Downward traction of the tenaculum and countertraction by the retractors help to determine the appropriate depth of the incision ( Fig. 51.4 ). The incision should be continued down to the cervical stroma. Once the appropriate depth of the incision is reached, the vaginal tissue will fall away from the underlying cervical tissue because there is a distinct plane between these two tissues ( Figs. 51.5 and 51.6 ).

      FIG. 51.2, The initial incision begins circumferentially at the reflection of the vaginal mucosa onto the cervix. A scalpel or electrosurgical instrument can be used.

      FIG. 51.5, Once the appropriate plane is reached, blunt dissection will usually lead to the posterior peritoneal reflection.

      FIG. 51.6, Once in the correct plane, the vaginal tissue is easily dissected off the underlying cervix, eventually allowing access to anterior peritoneal reflection.

    The vagina is mobilized both anteriorly and posteriorly. Once the appropriate plane has been reached, blunt dissection of the posterior vaginal wall will lead to the posterior cul-de-sac, which can be entered sharply ( Figs. 51.7 and 51.8 ). Once the peritoneum has been entered, the posterior cul-de-sac is explored for adhesive disease or any other potential abnormalities that may lead to difficulty in performing the hysterectomy. A Heaney or weighted retractor is then placed in the posterior cul-de-sac.

    FIG. 51.7, Sharp entrance into the posterior cul-de-sac.

    FIG. 51.8, The posterior cul-de-sac has been entered.

    The uterus is pulled outward and somewhat off to one side. Half of an open Heaney or similar clamp is introduced into the posterior cul-de-sac, and the uterosacral ligament is clamped ( Fig. 51.9 ). The tip of the clamp is advanced as far caudally to the cervix as possible so that the parametrium included in the clamp follows the line between the anterior and posterior incisions of the vagina ( Fig. 51.10 ). The Heaney clamp is then rotated toward the horizontal. The pedicle is cut with heavy scissors or a scalpel.

    • I prefer to ligate the pedicle with an absorbable suture, usually 0 Vicryl, with a strong needle attached to it ( Fig. 51.11 ). At times, bleeding from the posterior vaginal cuff may be encountered. The cut pedicle is suture-ligated with a transfixing-type suture in which the needle enters the upper part of the ligament pedicle just slightly beyond the end of the Heaney clamp. It is withdrawn and then reintroduced into the pedicle at its midpoint. These sutures are usually tagged for later identification of the uterosacral ligaments. I prefer to alternate clamping of pedicles on opposite sides instead of clamping up one side of the uterus and then the other. This will gradually improve uterine mobility and exposure. Sharp dissection is used to mobilize the bladder more anteriorly off the cervix. This should be done with Mayo or Metzenbaum scissors, especially in women with a previous cesarean section. The tips of the scissors should remain in proximity to the uterus until the bladder is mobilized off the uterus and the vesicouterine space is entered, exposing the lower edge of the peritoneum of the anterior cul-de-sac ( Figs. 51.12 and 51.13 ). There is never a benefit in rushing to enter the anterior cul-de-sac. This will lead only to inadvertent cystotomies. No attempt should be made to enter the anterior cul-de-sac until the vesicouterine space has been developed (see Figs. 51.12 and 51.13 ). Once the bladder has been mobilized ( Fig. 51.14 ), the cardinal ligament is clamped on each side ( Fig. 51.15 ). This pedicle, which should include peritoneal tissue posteriorly, is sutured in a similar fashion to the uterosacral ligaments. However, the second pass through the ligament is actually made through the previous pedicle, thus obliterating any dead space between the two pedicles to decrease the potential for bleeding or tearing of tissue.

      FIG. 51.14, The vesicouterine space has been entered. This allows placement of a retractor anteriorly, which mobilizes the bladder off the anterior cervix and exposes the peritoneal reflection of the anterior cul-de-sac.

    After the cardinal ligaments have been incised, a retractor is placed in the vesicouterine space to elevate the bladder off the uterus ( Fig. 51.16 ). If the anterior cul-de-sac is easily accessible, it can be entered at this time ( Figs. 51.16 to 51.18 ). The next clamp, which will probably include the uterine vessels, should incorporate the anterior and posterior peritoneal reflections if the anterior cul-de-sac has been entered ( Fig. 51.19 ). These clamps should be placed perpendicular to the longitudinal access of the cervix, and the tips of the clamps should completely slide off the cervix to ensure no inadvertent lateral migration and to avoid excessive bleeding or ureteral injury. As was previously mentioned, suturing of all pedicles involves passage of the needle through the tissue at the tip of the clamp and then a second pass through the previous pedicle. This will obliterate any dead space and eliminate potential bleeding between pedicles ( Fig. 51.20 ). Extra care should be taken to avoid passage of the needle through a vessel because this may lead to the development of a retroperitoneal hematoma.

    FIG. 51.20, A. The proper technique for clamping of the uterine vessels. B. The pedicle is sutured to ligate the vessels, as well as to incorporate the pedicle into the previously ligated pedicle. A suture is initially passed through the tissue at the tip of the clamp, and then a second pass of the needle is made through the distal end of the previous pedicle. C. This technique of ligating pedicles completely obliterates the dead space between pedicles. This technique is contrasted with the technique of ligating each pedicle individually, which results in gaps between pedicles that may lead to tearing of tissue with bleeding between pedicles.

    The uterus is then delivered anteriorly or posteriorly into the vagina ( Fig. 51.21 ). The fundus is grasped with the tenaculum and pulled into the vagina. The utero-ovarian ligament is supported by the index finger on the opposite side, and a clamp is placed close to the uterus. The last pedicle usually includes the fallopian tube and the round and ovarian ligaments. At times, these may be taken with one clamp, but usually a clamp placed from below is required, as well as a clamp placed from above ( Fig. 51.22 ). A finger should be maintained behind this pedicle to ensure that the clamps overlap posteriorly and that no other tissue has been included in the clamp (see Figs. 51.21 through 51.23 ). Once the final pedicles have been cut, the uterus is handed off to be sent to pathology. These pedicles are then doubly ligated. If one clamp has been used, a free tie is initially placed, followed by a suture-ligature. If two clamps have been used, each pedicle is individually ligated and then a figure-of-8 suture is placed through both pedicles. These sutures are tagged, and at this time all pedicles are inspected to ensure hemostasis ( Fig. 51.24 ). Because all pedicles have been sutured into the previous pedicle, no tearing or dead space between the pedicles should be noted ( Fig. 51.25 ).
