A comparison of vaginal, laparoscopic-assisted vaginal, and minilaparotomy hysterectomies for enlarged myomatous uteri

Objective

To compare the operative data and early postoperative outcome of vaginal hysterectomy (VH), laparoscopic-assisted vaginal hysterectomy (LAVH), and minilaparotomy hysterectomy (MiniLPT).

Methods

A total of 150 women who required hysterectomy for enlarged myomatous uteri were randomly allocated into 3 treatment groups: VH (n = 50), LAVH (n = 50), and MiniLPT (n = 50). The primary outcome was hospital discharge time. The secondary outcomes were operative time, blood loss, paralytic ileus, postoperative pain, and intraoperative and early postoperative complications.

Results

Mean hospital discharge time was longest with MiniLPT, and shortest with VH (P < 0.01). VH was the fastest operating technique, was associated with less blood loss, and resulted in shortest duration of paralytic ileus (P < 0.01). No intraoperative complications occurred.

Conclusion

VH should be the preferred surgical approach in patients with enlarged myomatous uteri. When VH is not feasible, LAVH should be considered an alternative to MiniLPT. Further controlled prospective studies are required to confirm these results.     

Wide genital hiatus is a risk factor for recurrence following anterior vaginal repair

Objective

To determine if a wide genital hiatus is a risk factor for recurrence of anterior vaginal wall prolapse following anterior vaginal repair.

Methods

A retrospective cohort study was performed on patients who had undergone an anterior vaginal wall repair. Patients were placed into 1 of 2 groups: wide genital hiatus (≥ 5 cm) or normal genital hiatus (< 5 cm). The wide genital hiatus group (n = 35) was compared with the normal genital hiatus group (n = 30) for surgical failure.

Results

There were no significant differences between the 2 groups in demographic data, additional operative procedures, or apical suspensions. The rate of postoperative anterior vaginal wall prolapse was greater in patients with a wide genital hiatus compared with those with a normal genital hiatus (34.3% vs 10% respectively; odds ratio 4.7 [95% confidence interval, 1.0-24.1]; P = 0.02).

Conclusion

The rate of recurrent anterior vaginal wall prolapse is higher in patients with a wide genital hiatus.     

Manometric evaluation of anal sphincter function after vaginal and cesarean delivery

Objective

To compare anal sphincter function following spontaneous vaginal delivery and cesarean delivery, and assess the association of perineal length and sphincter injury with each delivery mode.

Method

Perineal length was measured and anal manometric measurements were performed in 120 primigravidas before and after delivery.

Results

Mean values for maximum anal resting and squeeze pressures were significantly lower after delivery irrespective of the mode of delivery, but there was a positive correlation between postpartum maximum anal resting pressure and perineal length (r = 0.24, P < 0.01).

Conclusion

Anal sphincter function was disturbed after both vaginal and cesarean delivery, a finding weakened by the fact that almost half of the cesareans were performed for cephalopelvic disproportion identified during labor.     

Transobturator tape procedure versus tension-free vaginal tape for treatment of stress urinary incontinence

Objective

To compare the efficacy and safety of the tension-free vaginal tape (TVT) and inside-out transobturator tape (TVT-O) procedures for the treatment of stress urinary incontinence (SUI).

Methods

A total of 315 women with or without concomitant pelvic organ prolapse repairs were randomly allocated to undergo a TVT or TVT-O procedure. Demographic data, intra- and postoperative complications, and surgical outcomes were analyzed.

Results

Fifteen patients were lost to follow-up. There were no significant differences in cure rates between the 2 groups at 6, 12, 24, and 36 months' follow-up. Hematomas occurred in 4 patients and there were 6 vaginal tape erosions. Urinary retention and de novo urinary urgency were similar in both groups. The operative time was significantly shorter for TVT-O than for TVT without other procedures (P < 0.001) and postoperative groin/thigh pain was higher (P < 0.05) in the TVT-O group.

Conclusion

Both techniques appear equally effective for the treatment of SUI. However, TVT-O had a shorter operative time and a higher rate of groin/thigh pain.     

Outcome of investigations for postmenopausal vaginal bleeding in women under the age of 50 years

Objective

The objective of this study is to determine the incidence of endometrial cancer in young postmenopausal women presenting with vaginal bleeding.

Methods

Cross-sectional study of postmenopausal women presenting with vaginal bleeding in a gynaecological oncology centre in the United Kingdom. All women underwent transvaginal ultrasound scanning (TVS) as the initial investigation tool to evaluate the endometrium. Endometrial biopsy was performed only in cases where endometrial thickness measured equal to or greater than 5 mm. The patients were divided into two groups based on their age: less than 50 years (Group A) and 50 years or older (Group B).

Results

Over a 57-month period, 4454 women were investigated for postmenopausal vaginal bleeding. Of these, 259 (5.8%) women were diagnosed with endometrial carcinoma. 260 (5.8%) women were younger than 50 years. Endometrial biopsy was not performed in 130 women in Group A that had an endometrial thickness measurement of less than 5 mm on ultrasonography. With a median follow-up period of 3 (1-5) years, we found no cases of endometrial cancer in women under the age of 50 that did not undergo endometrial biopsy at the time of initial evaluation. Overall, no cases of endometrial cancer were diagnosed in postmenopausal women under the age of 50 years.

Conclusions

We found no cases of endometrial cancer amongst 260 women presenting with postmenopausal vaginal bleeding under the age of 50 years. These women could be investigated on a less urgent basis depending on the available resources.     

Infección vaginal por tricomonas (e infecciones mixtas) y atipias celulares, en la citología cervicovaginal

Objective

We present a series of 380 cytologies with a diagnosis of vaginal infection due to Trichomonas vaginalis, representing 0.31% of 121,688 cytologies in a 10-year period (2000-2009). We compared these cytologies with a control group of 535 cytologies.

Results

Cytology detecting Trichomonas showed greater inflammation and mixed infections were found in 36 cases (9.4). Atypia were found in 19 cases (5%).

Conclusions

In our study, vaginal infection due to Trichomonas in the cytology was significantly associated with bacterial vaginosis (P < .05) and atypia of undetermined significance (ASCUS) (P < .01).     

Preoperative urodynamic predictors of short-term voiding dysfunction following a transobturator tension-free vaginal tape procedure

Objective

To determine whether preoperative urodynamic parameters can predict the development of short-term voiding dysfunction (VD) after a transobturator tension-free vaginal tape (TO-TVT) procedure.

Methods

In a prospective study between April 2005 and April 2007, 341 women were randomized to receive “inside-out” or “outside-in” TO-TVT. The present secondary analysis included women who had completed a preoperative symptom questionnaire, had a voided volume of 100 mL or more on preoperative uroflowmetry, and underwent standardized postoperative voiding assessment. VD was defined as a requirement for postoperative catheterization. Univariate and multivariate analysis were done by SPSS 17.

Results

The inclusion criteria were met by 224 women, of whom 17 (7.6%) had postoperative VD. On univariate analysis, there were no differences in preoperative parameters among those with and those without VD: residual urine volume (P = 0.485), peak flow rate on or below 5th centile (P = 0.272), average flow rate on or below 5th centile (P = 0.142), detrusor pressure at opening (P = 0.955), maximum urethral closure pressure at 30 cm H₂O or less (P = 0.855) and functional urethral length (P = 0.173). None of the variables analyzed was an independent risk factor on multivariate analysis.

Conclusion

Preoperative urodynamic parameters did not predict the development of short-term voiding dysfunction after a TO-TVT procedure.     

Rate of vaginal cuff separation following laparoscopic or robotic hysterectomy

Objective

Vaginal cuff separation is a rare but serious complication following hysterectomy. The goal of our study was to determine the rate of vaginal cuff separation and associated risk factors in patients undergoing laparoscopic or robotic hysterectomy.

Methods

We retrospectively identified patients who underwent a minimally invasive simple or radical hysterectomy at one institution between January 2000 and 2009. Fisher's exact test, Wilcoxon rank sum test and multiple logistic regression were used to determine associations between variables and increased risk of separation.

Results

A total of 417 patients underwent laparoscopic (n = 285) or robotic (n = 132) hysterectomy during the study period. Three hundred and sixty-two underwent simple hysterectomy (249 laparoscopic, 113 robotic) and 57 underwent radical hysterectomy (36 laparoscopic, 19 robotic). Seven (1.7%) patients developed a cuff complication and all had a diagnosis of malignancy. Three (1.1%) patients in the laparoscopy group suffered a vaginal cuff evisceration (n = 2) or separation (n = 1). Four patients in the robotic group (3.0%) had a vaginal evisceration (n = 1) or separation (n = 3). There was no difference based on surgical approach (p = 0.22). Vaginal cuff complications were 9.46-fold higher among patients who had a radical hysterectomy (p < 0.01). Median time to presentation of vaginal cuff complication was 128 days (range, 58-175) in the laparoscopy group and 37 days (range, 32-44) in the robotic group.

Conclusions

The overall risk of vaginal cuff complication was 1.7%. There appears to be no difference in cuff complication rates based on surgical approach. Radical hysterectomy, however, was associated with a 9-fold increase in vaginal cuff complications.     

Oral misoprostol reduces vaginal bleeding following surgical evacuation for first trimester spontaneous abortion

Objective

To assess the effectiveness and tolerability of misoprostol to reduce the amount and duration of vaginal bleeding following surgical evacuation for first trimester spontaneous abortion.

Methods

A total of 160 patients who underwent surgical evacuation for first trimester spontaneous abortion between 8 and 12 weeks of pregnancy were randomized into 2 groups to receive either 200 µg of oral misoprostol immediately after evacuation followed every 6 hours for 48 hours or no misoprostol. Pain scores, duration and amount of bleeding, and endometrial thickness were assessed over 10 days.

Results

Women who received misoprostol had significantly fewer bleeding days after evacuation (4.11 ± 2.69 vs 5.89 ± 3.06; P < 0.001), fewer patients reported vaginal bleeding lasting 10 days or more (3.8% vs 15.0%; P = 0.014), and endometrial thickness 10 days after evacuation was less (6.25 ± 2.38 vs 7.23 ± 1.94; P = 0.05). Pain scores were comparable in both groups (1.54 ± 0.65 vs 1.63 ± 0.83; P = 0.40) after 10 days.

Conclusion

Oral misoprostol is effective in reducing the prevalence and amount of vaginal bleeding after surgical evacuation for first trimester spontaneous abortion.     

A 5-year prospective study of vaginal pessary use for pelvic organ prolapse

Objective

To evaluate prospectively the use of vaginal pessaries for pelvic organ prolapse (POP) and to identify complications and reasons for discontinuing pessary use over a 5-year period.

Methods

A prospective observational study was conducted among all women with POP referred to the urogynecology clinic of a UK hospital between June 2002 and June 2005 who opted to use a vaginal pessary. Patients were followed-up for 5 years.

Results

Of the 246 women who chose to use a vaginal pessary, 187 successfully retained the pessary 4 weeks after insertion. Over a 5-year period, 36 (19.3%) of the 187 women were lost to follow-up. Of the 151 women included in the analysis, 21 (13.9%) discontinued use at some point after 4 weeks, whereas 130 (86.1%) used the pessary successfully over 5 years. Overall, 12.1% of the women experienced minor complications (6.9% pain or discomfort, 3.2% excoriation or bleeding, and 2.0% disimpaction or constipation). Most failures (73.8%) occurred within 4 weeks of pessary insertion. After cessation of pessary use, 70 (28.5%) of the 246 women chose surgery and 10 (4.1%) chose no further treatment.

Conclusion

If treatment of POP with a vaginal pessary is successful at 4 weeks, most women will continue to use the pessary over 5 years without a concomitant increase in complications.     

De novo urgency after tension-free vaginal tape versus transobturator tape procedure for stress urinary incontinence

Objective

To determine the frequency of de novo urgency after tension-free vaginal tape (TVT) compared with the transobturator tape (TOT) procedure in women with stress urinary incontinence (SUI).

Study design

Prospective study of all consecutive women with urodynamically confirmed SUI undergoing anti-incontinence surgery between January 2000 and January 2008. All procedures were performed by experienced urogynaecologists well trained in TVT and TOT surgery. Assessments were carried out at 1, 6, 12 and, 36 months after surgery.

Results

The study population included 366 women (mean age 59.5 years), 243 in the TVT group and 123 in the TOT group. The groups were similar in terms of demographics, preoperative data, and cure rates. De novo urgency occurred in 13.4% of patients at 6 months after surgery, in 19.3% at 12 months, and in 22.1% at 36 months. De novo urgency was significantly more frequent in the TVT group than in the TOT group at 12 (22.2% vs 11.2%, P = 0.025), 24 (24.8% vs 12.3%, P = 0.033), and 36 (0% vs 24.7%, P = 0.034) months. Cure rates were similar in both groups. The final adjusted cure rate was 87.3% (319/366).

Conclusion

Treatment of SUI using the TOT procedure was associated with a lower rate of de novo urgency.     

Transretropubic traction vaginoplasty for correction of vaginal aplasia

Objective

To introduce an alternative approach to vaginoplasty using transretropubic traction (TRT).

Methods

In this case series with 4 patients with complete vaginal aplasia, a plastic “olive” placed on the vaginal dimple was lifted by a mesh tape inserted through the space of Retzius and anchored to the anterior abdominal wall.

Results

On day 8 postoperatively all patients had a reasonable vaginal size, 2.5 to 3 cm in width and 6 to 7.5 cm in length. The mean satisfaction scores were 86 points for the patients and 89 points for their husbands, who also reported a mean penetration score of 90 points.

Conclusion

As a minimal-access and relatively simple operation, TRT vaginoplasty could be performed by trained gynecologists. Studies with larger populations are required to support this preliminary report.     

Risk factors for vaginal prolapse after hysterectomy

Objective

To identify risk factors for pelvic organ prolapse (POP) and their influence on the occurrence of vaginal prolapse after hysterectomy.

Methods

Medical records from 2 groups of women who had undergone hysterectomy were reviewed retrospectively. The study group was 82 women who had undergone surgery for vaginal prolapse after hysterectomy; the control group was 124 women who had undergone hysterectomy with no diagnosis of vaginal prolapse by the time of the study. All hysterectomy procedures had been performed for benign gynecological disease, including POP. Both groups of women completed a self-administered questionnaire to obtain additional information on the occurrence of POP.

Results

The incidence of vaginal prolapse after hysterectomy was significantly higher in women with a higher number of vaginal deliveries, more difficult deliveries, fewer cesareans, complications after hysterectomy, heavy physical work, neurological disease, hysterectomy for pelvic organ prolapse, and/or a family history of pelvic organ prolapse. Premenopausal women had vaginal prolapse corrected an average of 16 years after hysterectomy, and postmenopausal women 7 years post hysterectomy.

Conclusion

Before deciding on hysterectomy as the approach to treat a woman with pelvic floor dysfunction, the surgeon should evaluate these risk factors and discuss them with the patient.     

Vaginal length and incidence of dyspareunia after total abdominal versus vaginal hysterectomy

Objective

To evaluate the vaginal length and incidence of dyspareunia after total abdominal hysterectomy compared to vaginal hysterectomy.

Study design

This is a prospective observational study. Sixty-six patients were invited to participate in the study who were already planned to undergo abdominal or vaginal hysterectomy for different benign indications in the OB/GYN department, Sohag University Hospital, during the period from March 2007 till April 2009. Patients were classified into two groups. Thirty-six patients who were planned to undergo total abdominal hysterectomy (TAH) represented the first group, and 30 patients who were planned to undergo vaginal hysterectomy (VH) represented the second group. Vaginal length was obtained just before the operation and three times postoperatively. Pre- and post-operative dyspareunia was reported.

Results

The mean pre-operative and post-operative vaginal lengths in the TAH group were nearly the same (10.5 ± 2.1 cm vs. 10.2 ± 1.8 cm) without statistically significant difference. In the VH group, there was a statistically significant difference between pre- and post-operative vaginal length (10.1 ± 1.9 cm vs. 8.4 ± 1.6 cm). In the TAH group, 2 patients (5%) reported a newly developed post-operative dyspareunia. In VH group, 6 patients (20%) developed dyspareunia after surgery.

Conclusion

Postoperative dyspareunia is more common after vaginal hysterectomy compared to abdominal hysterectomy. This may be attributed to postoperative shortening of the vagina secondary to excessive trimming of the vaginal walls especially if VH was done for utero-vaginal prolapse.     

Uterosacral-cardinal ligament stretching prior to vaginal hysterectomy increases uterine descent: a novel technique

Objective

To examine the effect of uterosacral-cardinal ligament complex stretching prior to vaginal hysterectomy on uterine descent.

Study design

A prospective trial of 25 consecutive women undergoing vaginal hysterectomy. Pre-operative, apical, anterior and posterior wall POP-Q measurements were recorded for each patient before and after uterosacral-cardinal ligament complex stretching during general anesthesia.

Results

Uterosacral-cardinal ligament complex stretching yielded a significant increase in mean stage of uterine and anterior wall descent (2.6 ± 0.6 vs. 3.2 ± 0.6 cm, p < 0.001, and 2.5 ± 0.8 vs. 2.9 ± 0.8 cm, respectively, p < 0.004). There was no significant change in posterior wall prolapse measurements (1.3 ± 0.7 vs. 1.4 ± 0.8 cm, p = 0.05).

Conclusion

Uterosacral-cardinal ligament complex stretching prior to vaginal hysterectomy increase uterine descent.     

Midtrimester abortion using vaginal misoprostol for women with three or more prior cesarean deliveries

Objective

To evaluate the safety and efficacy of vaginal misoprostol for second-trimester abortion in women with 3 or more prior cesarean deliveries.

Methods

This study was conducted with 138 women who needed pregnancy termination between 13 and 26 gestational weeks, 31 with 3 or more previous cesarean deliveries and 107 with no uterine scars (the controls). Misoprostol was inserted in the vagina every 6 hours until regular contractions or products of conception appeared, a 200-µg tablet for the first 24 hours and 2 tablets thereafter. The outcomes assessed were successful vaginal abortion, hemorrhage requiring blood transfusion, incomplete abortion, and uterine rupture.

Results

A vaginal abortion occurred in 28 women (90.3%) in the study group and 107 (100%) in the control group (P = 0.01). There were no significant differences in the prevalence of the other assessed outcomes.

Conclusion

Vaginal misoprostol appears to be safe and acceptably effective for second-trimester pregnancy termination in women with 3 or more previous cesarean deliveries.     

Efficacy of mifepristone in reducing intermenstrual vaginal bleeding in users of the levonorgestrel intrauterine system

Objective

To evaluate the efficacy of mifepristone to reduce intermenstrual bleeding in levonorgestrel intrauterine system (LNG-IUS) users.

Method

In this prospective, open-label, comparative study, 36 women using the LNG-IUS for menorrhagia received 100 mg of mifepristone every 30 days for 3 months (group 1). Fifty age-matched LNG-IUS users who did not receive any drugs were used as the comparison group (group 2). Menstrual bleeding days, pictorial blood loss assessment chart (PBAC) score, and intermenstrual bleeding/spotting days were compared between the 2 groups at 3 months (during treatment) and at 6 months (3 months post treatment).

Results

Baseline characteristics were comparable between the groups. At 3 months, median duration and episodes of intermenstrual bleeding/spotting were significantly lower in group 1 compared with group 2 (6 vs 12.5 days, P = 0.01; 2.5 vs 3, P = 0.05, respectively). More women were satisfied with the LNG-IUS in the mifepristone group compared with the control group (75% vs 44%; P = 0.004). At 6 months, the median duration of intermenstrual bleeding/spotting was significantly lower in group 1 compared with group 2 (6 vs 15 days; P = 0.008).

Conclusion

Mifepristone was effective in reducing the number of episodes and duration of intermenstrual bleeding/spotting in LNG-IUS users.     

Induction of labor with vaginal misoprostol plus oxytocin versus oxytocin alone

Objective

To compare the effect of an oxytocin infusion alone or preceded by an intravaginal application of misoprostol for labor induction in women with term pregnancies and a low Bishop score.

Methods

This study randomized 100 multiparous women with singleton pregnancies over 38 weeks and a Bishop score less than 6 to receive either a single 50-µg dose of misoprostol intravaginally 3 hours before initiation of the oxytocin infusion or only an oxytocin infusion. The time from induction to delivery, the route of delivery, and maternal and fetal outcomes were analyzed.

Results

The mean time from induction to delivery was 9.36 ± 1.97 hours in the misoprostol plus oxytocin group and 11.08 ± 3.23 in the oxytocin alone group (P = 0.002). The rates of vaginal delivery, 1- and 5-minute Agpar scores, placental abruption, and postpartum hemorrhage were similar between the 2 groups, as were the rates of admission to the neonatal intensive care unit. There were no cases of perinatal asphyxia.

Conclusion

A 50-µg intravaginal application of misoprostol before starting the oxytocin infusion is a more effective method of labor induction than an oxytocin infusion alone for our study population.     

Complications of mid-urethral slings for treatment of stress urinary incontinence

Objective

To compare the incidence of complications associated with the use of retropubic tension-free vaginal tape (TVT) and transobturator tension-free vaginal tape (TVT-O) for the management of stress urinary incontinence (SUI).

Methods

In a cross-sectional study, 1081 patients were treated for SUI via mid-urethral slings, and the outcomes of those treated via TVT and those treated via TVT-O were compared. Patients who suffered from recurrent or mixed urinary incontinence were excluded.

Results

Group 1 included patients treated via TVT (n = 207) and group 2 included those treated with TVT-O (n = 570). There was a higher incidence of bladder perforation (5.4% versus 0.6%; P = 0.001) and hematoma formation (9.1% versus 1.5%; P = 0.001) in group 1 than in group 2. Compared with group 1, there was higher incidence of vaginal wall perforation in group 2 (0.0% versus 3.8%, P = 0.044). The rate of intraoperative complications was not related to patient age, body mass index, or parity. Of the patients who did not leak urine during a cough test 1 month after surgery, 90.9% still had a negative cough test at the long-term follow-up.

Conclusion

TVT-O was superior to TVT with regard to the incidence of bladder perforation and hematoma formation, but it resulted in more vaginal wall injuries.     

Sedation with local versus general anesthesia for the tension-free vaginal tape Secur hammock procedure

Objective

To compare the intraoperative and immediate postoperative results achieved with the tension-free vaginal tape Secur (TVT-S) hammock procedure performed under local anesthesia (LA) versus general anesthesia (GA).

Methods

Prospective randomized trial involving patients with symptomatic stress urinary incontinence grades 1 or 2 who underwent TVT-S under either LA or GA. Postoperative pain intensity, duration of hospitalization, rate of complications, duration of operating and recovery times, and number of additional procedures required were recorded.

Results

Each group included 40 patients. The operative times were identical in the 2 groups, but the time spent in the recovery room was significantly longer in the GA group. Patients undergoing LA experienced less pain than did those undergoing GA. Most patients in the LA group had day surgery, whereas most patients in the GA group went home 1 day after the surgery. No significant differences were observed for the rates of complications.

Conclusion

Performing the TVT-S hammock technique under LA rather than GA reduces postoperative pain and shortens the duration of hospitalization.
