Surgical management of pelvic organ prolapse in women

A Retrospective Cohort Study of vNOTES Extraperitoneal Versus Laparoscopic Sacral Hysteropexy With Uterine Preserving Regarding Surgical Outcomes and 2 Year Follow-up Results

STUDY OBJECTIVE

To explore the effectiveness of transvaginal natural orifice transluminal endoscopic surgery extraperitoneal sacral hysteropexy (vNOTES-ESH) in women with symptomatic uterine prolapse over a 2 year follow-up.

DESIGN

Retrospective cohort study.

SETTING

Gynecological minimally invasive center.

PATIENTS

Women undergoing sacral hysteropexy either by vNOTES (n = 25) or laparoscopic (n = 74) between November 2016 and December 2020.

INTERVENTIONS

Both vNOTES-ESH and laparoscopic sacral hysteropexy (LAP-SH) were used for uterine prolapse. Demographic data, operative characteristics, perioperative outcomes, and follow-up information 2 years postsurgery in the 2 groups were retrospectively evaluated.

RESULTS

Both procedures showed similar operation time, estimated blood loss, hospital stays, and pain scores (p >0.05). During a median follow-up of 59 (24-72) months, the surgical success rate was 96% for vNOTES-ESH and 97.3% for LAP-SH (p >0.05), with no differences in anatomical position or pelvic organ function after the operation. Women in the LAP-SH group experienced more bothersome symptoms of constipation compared to those in the vNOTES-ESH group (5.41% vs 0, p <0.05). Lastly, 1 case in the vNOTES-ESH group had a mesh exposed area of less than 1 cm2, and 1 patient in the LAP-SH group experienced stress incontinence.

CONCLUSIONS

In this retrospective study, vNOTES-ESH met our patients' preference for uterine preservation and was a successful and effective treatment for uterine prolapse, providing good functional improvement in our follow-up. This procedure should be considered as an option for patients with pelvic organ prolapse.

Outcomes of robotic sacrocolpopexy

This review aimed to summarize the complications and surgical outcomes of robot-assisted sacrocolpopexy. Nineteen original articles on 1,440 robotic sacrocolpopexies were reviewed, and three systematic reviews and meta-analyses were summarized in terms of intraoperative, perioperative, postoperative, and/or surgical outcomes. Robotic sacrocolpopexy has demonstrated low overall complication rates and favorable surgical outcomes. Nevertheless, long-term follow-up outcomes regarding objective and/or subjective prolapse recurrence, reoperation rates, and mesh-related complications remain unclear. Further research is required to demonstrate whether the robotic approach for sacrocolpopexy is feasible or can become the modality of choice in the future when performing sacrocolpopexy.

Sexual Function after Minimally Invasive Total Hysterectomy and Sacrocolpopexy

STUDY OBJECTIVE

To evaluate sexual function in women undergoing minimally invasive total hysterectomy and sacrocolpopexy (TLH + SCP) with a lightweight polypropylene Y-mesh 1 year after surgery.

DESIGN

This was a planned secondary analysis of a 5-site randomized trial comparing permanent (2-0 Gore-Tex; W. L. Gore & Associates, Inc., Newark, DE) vs absorbable suture (2-0 polydioxanone suture) for vaginal attachment of a Y-mesh (Upsylon; Boston Scientific Corporation, Natick, MA) graft during TLH + SCP.

SETTING

Multicenter trial at 5 study sites (4 academic and 1 community). The study sites were: (1) University of North Carolina at Chapel Hill, Chapel Hill, NC; (2) Wake Forest Baptist Hospital, Winston-Salem, NC; (3) Northwestern University, Evanston, IL; (4) Georgia Regents University, Augusta, GA; and (5) Atlantic Health Medical Group, Morristown, NJ.

PATIENTS

Women previously enrolled in an original study undergoing TLH + SCP.

INTERVENTIONS

Quality-of-life questionnaires and physical examination.

MEASUREMENTS AND MAIN RESULTS

The primary objective was to assess changes in sexual function at 1 year after surgery as measured by the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire, International Urogynecological Association-Revised. The secondary objective was to assess the factors associated with postoperative sexual activity and dyspareunia. Of the 200 participants enrolled, 182 (92.8%) completed follow-up: n = 95/99 Gore-Tex and n = 87/101 polydioxanone suture. The mean age was 60 ± 10 years; body mass index was 27 ± 5 kg/m²; 78% were menopausal and 56% sexually active before surgery. At 1 year after surgery, 63% were sexually active: 93% of the sexually active women preoperatively remained so at 1 year, and 24% reported new sexual activity at 1 year (p <.001). Sexual function at 1 year showed marked improvement in activity, quality, and arousal/orgasm compared with baseline Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire scores. Dyspareunia rates decreased from 22% preoperatively to 16.5% at 1 year (p = .65). Women who were sexually active at 1 year were younger (56.8 ± 9.6 years vs 65.4 ± 9.2 years, p <.001), more likely to be premenopausal (31.6% vs 7.4%, p = .001), and less likely to undergo bilateral salpingo-oophorectomy (53.3% vs 78.9%, p <.001).

CONCLUSION

Women undergoing TLH + SCP with a lightweight mesh graft report increased rates of sexual activity, improved sexual quality and arousal/orgasm, and lower rates of dyspareunia at 1 year after surgery.

Effectiveness of ring pessaries versus vaginal hysterectomy for advanced pelvic organ prolapse. A cohort study

INTRODUCTION AND HYPOTHESIS

This study aimed to evaluate the efficacy of the ring pessary compared with surgery as a primary treatment for advanced pelvic organ prolapse (POP) in non-hysterectomized, postmenopausal women. Our starting hypothesis was that the pessary is as effective as and less risky than surgery.

METHODS

This study was a prospective observational study, which recruited 171 women with symptomatic advanced POP in a tertiary hospital for 30 months. They were treated according their preference with either surgery [77/171 (45.0%)] or vaginal ring pessary without support [94/171 (55.0%)]. The primary outcomes included the discontinuation of pessary use and the incidence of recurrent prolapse throughout the study. Secondary outcomes included complications categorized according to Clavien-Dindo classification. Descriptive statistics were used for demographic data. The mean and standard deviation were calculated for continuous variables, and continuity correction tests, Mann-Whitney U tests, and Fisher's exact tests were used for categorical variables.

RESULTS

There was successful use of a pessary in 84.4% (76/90) of cases, and 89.6% (69/77) of patients did not have prolapse recurrence in the surgical group (>POP-Q 2). In the pessary group, the adverse event rate was 31.6%, and all were Clavien-Dindo grade I. Thirty patients [30/77 (39.0%)] had complications in the surgery group: 14.3% were Clavien-Dindo grade I (11/77), 10.4% were grade II (8/77), and 14.3% were grade III (11/77).

CONCLUSIONS

The pessary is effective and has mild adverse events in non-hysterectomized, postmenopausal women with advanced POP.

Effect of modified laparoscopic hysterectomy on pelvic floor function: A retrospective observational study

Hysterectomy is a potential risk factor for subsequent surgery for pelvic organ prolapse, especially when the prolapse exists before hysterectomy. Women without prolapse before hysterectomy may also experience prolapse after hysterectomy. This study aimed to describe a surgical modification of laparoscopic colposuspension with round ligaments after hysterectomy in women without preexisting genital prolapse and to evaluate the initial surgical results in these patients.We reviewed data of 54 patients who underwent laparoscopic hysterectomy with colposuspension with unilateral or bilateral round ligaments after hysterectomy at Chia-Yi Chang Gung Memorial Hospital from July 2012 to March 2015. Vaginal length was measured before and after colposuspension after complete hysterectomy. Preoperative characteristics of the patients, perioperative quality, postoperative outcomes, and vaginal length differences were analyzed.Vaginal length increased by a mean of 2.59 cm after colposuspension. The mean extra-operative time needed for laparoscopic colposuspension was about 10 minutes. No severe complications were reported in our patients, and we did not find any cystocele after completing vaginal cuff suspension to the round ligament.The vaginal apex level was maintained in our modified laparoscopic hysterectomy. Therefore, laparoscopic colposuspension with round ligaments is a promising option as a routine, first-line standard procedure in younger women without genital prolapse to maintain an acceptable vaginal length after laparoscopic hysterectomy.

Treatment of vaginal vault prolapse in The Netherlands: a clinical practice survey

INTRODUCTION AND HYPOTHESIS

A great variety of conservative and surgical procedures to correct vaginal vault prolapse have been reported. The aim of this study was to describe practice pattern variation-the difference in care that cannot be explained by the underlying medical condition-among Dutch gynecologists regarding treatment of vaginal vault prolapse.

METHODS

A clinical practice survey was conducted from March to April 2017. The questionnaire was developed to evaluate treatment of vaginal vault prolapse. All members of the Dutch Society for Urogynaecology were invited to participate in a web-based survey.

RESULTS

One hundred four Dutch gynecologists with special interest in urogynecology responded to the survey (response rate, 44%). As first-choice therapy for vaginal vault prolapse, 78% of the respondents chose pessary treatment, whereas sacrospinous fixation was the second most common therapy choice according to 64% of the respondents. Preferences on how to approach vaginal vault prolapse surgically are conflicting. Overall, the most performed surgery for vaginal vault prolapse is sacrospinous fixation, followed by laparoscopic and robotic sacrocolpopexy.

CONCLUSIONS

Gynecologists in The Netherlands manage vaginal vault prolapse very differently. No standardized method could be determined for the treatment of vaginal vault prolapse in The Netherlands, and we observed practice pattern variations.

Perioperative interventions in pelvic organ prolapse surgery

BACKGROUND

Pelvic organ prolapse (POP) affects as many as 50% of parous women, with 14% to 19% of women undergoing a surgical correction. Although surgery for the treatment of POP is common, limited supportive data can be found in the literature regarding the preoperative and postoperative interventions related to these procedures. The main goal of perioperative interventions is to reduce the rate of adverse events while improving women's outcomes following surgical intervention for prolapse. A broad spectrum of perioperative interventions are available, and although the benefits of interventions such as prophylactic antibiotics before abdominal surgery are well established, others are unique to women undergoing POP surgeries and as such need to be investigated separately.

OBJECTIVES

The aim of this review is to compare the safety and effectiveness of a range of perioperative interventions versus other interventions or no intervention (control group) at the time of surgery for pelvic organ prolapse.

SEARCH METHODS

We searched the Cochrane Incontinence Group Specialised Register, which contains trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, MEDLINE In Process, ClinicalTrials.gov, WHO ICTRP, handsearching of journals and conference proceedings (searched 30 November 2017), and reference lists of relevant articles. We also contacted researchers in the field.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) of women undergoing surgical treatment for symptomatic pelvic organ prolapse that compared a perioperative intervention related to pelvic organ prolapse surgery versus no treatment or another intervention.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures recommended by Cochrane. Our primary outcomes were objective failure at any site and subjective postoperative prolapse symptoms. We also measured adverse effects, focusing on intraoperative blood loss and blood transfusion, intraoperative ureteral injury, and postoperative urinary tract infection.

MAIN RESULTS

We included 15 RCTs that compared eight different interventions versus no treatment for 1992 women in five countries. Most interventions were assessed by only one RCT with evidence quality ranging from very low to moderate. The main limitation was imprecision, associated with small sample sizes and low event rates.Pelvic floor muscle training (PFMT) compared with no treatment (three RCTs) - peri-operative intervention The simplest of the PFMT programmes required women to attend six perioperative consultations in the three months surrounding prolapse surgery. Trial results provided no clear evidence of a difference between groups in objective failure at any site at 12 to 24 months (odds ratio (OR) 0.93, 95% confidence interval (CI) 0.56 to 1.54; two RCTs, 327 women; moderate-quality evidence). With respect to awareness of prolapse, findings were inconsistent. One RCT found no evidence of a difference between groups at 24 months (OR 1.07, 95% CI 0.61 to 1.87; one RCT, 305 women; low-quality evidence), and a second small RCT reported symptom reduction from the Pelvic Organ Prolapse Symptom Questionnaire completed by the intervention group at 12 months (mean difference (MD) -3.90, 95% CI -6.11 to -1.69; one RCT, 27 women; low-quality evidence). Researchers found no clear differences between groups at 24-month follow-up in rates of repeat surgery (or pessary) for prolapse (OR 1.92, 95% CI 0.74 to 5.02; one RCT, 316 women; low-quality evidence).Other interventionsSingle RCTs evaluated the following interventions: preoperative guided imagery (N = 44); injection of vasoconstrictor agent at commencement of vaginal prolapse surgery (N = 76); ureteral stent placement during uterosacral ligament suspension (N = 91); vaginal pack (N = 116); prophylactic antibiotics for women requiring postoperative urinary catheterisation (N = 159); and postoperative vaginal dilators (N = 60).Two RCTs evaluated bowel preparation (N = 298), and four RCTs assessed the method and timing of postoperative catheterisation (N = 514) - all in different comparisons.None of these studies reported our primary review outcomes. One study reported intraoperative blood loss and suggested that vaginal injection of vasoconstrictors at commencement of surgery may reduce blood loss by a mean of about 30 mL. Another study reported intraoperative ureteral injury and found no clear evidence that ureteral stent placement reduces ureteral injury. Three RCTs reported postoperative urinary tract infection and found no conclusive evidence that rates of urinary tract infection were influenced by use of a vaginal pack, prophylactic antibiotics, or vaginal dilators. Other studies did not report these outcomes.

AUTHORS' CONCLUSIONS

There was a paucity of data about perioperative interventions in pelvic organ prolapse surgery. A structured programme of pelvic floor muscle training before and after prolapse surgery did not consistently demonstrate any benefit for the intervention; however, this finding is based on the results of two small studies. With regard to other interventions (preoperative bowel preparation and injection of vasoconstrictor agent, ureteral stent placement during uterosacral ligament suspension, postoperative vaginal pack insertion, use of vaginal dilators, prophylactic antibiotics for postoperative catheter care), we found no evidence regarding rates of recurrent prolapse and no clear evidence that these interventions were associated with clinically meaningful reductions in adverse effects, such as intraoperative or postoperative blood transfusion, intraoperative ureteral injury, or postoperative urinary tract infection.

Laparoscopic versus abdominal sacrocolpopexy for treatment of multi-compartmental pelvic organ prolapse: A systematic review

Laparoscopic sacrocolpopexy (LSC) is attracting increasing attention as a minimally invasive surgery that provides excellent therapeutic effects on apical vaginal prolapse. However, its therapeutic effects on multi-compartmental pelvic organ prolapse (POP) remain unclear. Therefore, the aim of this review was to evaluate the efficacy of LSC on multi-compartmental POP compared with abdominal sacrocolpopexy (ASC). We extracted three articles on randomized controlled trials that compared LSC and ASC. A total of 247 patients (123 for LSC, 124 for ASC) were evaluated. There was no evidence of recurrence or reoperation in either group for the apical vaginal compartment. Regarding recurrence within the anterior vaginal compartment, there were no significant between-group differences in either of the two randomized controlled trials targeting vaginal vault prolapse. In contrast, in the randomized controlled trial targeting POP including cases with uteruses, there were more recurrent POP with grade II or more in the LSC group than in the ASC group (11/60 [18.3%] vs 1/60 [1.6%], P = 0.004). Reoperation for the posterior vaginal compartment was performed in three cases (2.5%) in the LSC group and in one case (0.8%) in the ASC group. The combined repeat surgery and mesh removal surgery rate was higher in the LSC group (8/119 [6.7%]) than in the ASC group (2/121 [1.7%], P = 0.049). LSC has an excellent therapeutic effect and is comparable to ASC for the treatment of apical prolapse. However, cystocele recurrence, repeat surgery of the posterior compartment, and mesh-related complications were more frequent in patients who had undergone LSC.

Abdominal sacrocolpopexy with Pelvicol xenograft and concomitant Burch colposuspension

Purpose

To evaluate the efficacy of Pelvicol xenograft use during abdominal sacrocolpopexy to repair pelvic organ prolapse (POP).

Patients and methods

A total of 27 consecutive women with symptomatic POP were included in this study. A POP-quantification system and International Continence Society classification were used. Functional and anatomical outcomes were assessed. Subjective outcomes and physical activity after surgery were evaluated due to modified quality of life questionnaire.

Results

Median follow-up was 21 months (range: 16 to 41 months). Twenty-four (89%) patients were available for anatomical and subjective evaluation. Preoperative POP-quantification classification was: stage I: 11.1%, stage II: 25.9%, stage III: 48.2%, and stage IV: 14.8%. Overall, pad usage significantly decreased (mean 4.8 vs 1 pads, P=0.001). Stress urinary incontinence significantly improved after surgery in nine women (P=0.001). An additional five women were completely continent. No de-novo incontinence developed. Six women with preoperative urinary retention improved in the amount of residual urine postoperative (mean 35 vs 165 mL). Failure rate was 8.3% at 3 and 11 months after surgery, requiring a second reconstruction. There was no graft related complications or graft rejections necessitating removal occurring. Response rate of the questionnaire was 67%. Two women reported no interference in physical activity after 2 postoperative months, five women after 5 months, and five women 1 year later. Pelvic pain (vaginal pain) was partly improved in eight patients, postoperatively, and ten patients had complete resolution of pain after surgery.

Conclusion

This study demonstrates that abdominal sacrocolpopexy is an effective surgical treatment in correcting POP. The use of Pelvicol is associated with a high recurrence rate and increased failure rate compared to traditional sacrocolpopexy with mesh. Larger clinical trials to evaluate the functional and anatomical outcomes are needed.

Anterior vaginal repair for urinary incontinence in women

BACKGROUND

Anterior vaginal repair (anterior colporrhaphy) is an operation traditionally used for moderate or severe stress urinary incontinence (SUI) in women. About a third of adult women experience urinary incontinence. SUI imposes significant health and economic burden to the society and the women affected.

OBJECTIVES

To determine the effects of anterior vaginal repair (anterior colporrhaphy) on urinary incontinence in comparison with other management options.

SEARCH METHODS

We searched the Cochrane Incontinence Group Specialised Trials Register (searched 1 September 2009) and the reference lists of relevant articles.

SELECTION CRITERIA

Randomised or quasi-randomised trials that included anterior vaginal repair for the treatment of urinary incontinence.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data and assessed trial quality. Three trial investigators were contacted for additional information.

MAIN RESULTS

Ten trials were identified which included 385 women having an anterior vaginal repair and 627 who received comparison interventions.A single small trial provided insufficient evidence to assess anterior vaginal repair in comparison with physical therapy. The performance of anterior repair in comparison with bladder neck needle suspension appeared similar (risk ratio (RR) for failure after one year 1.16, 95% confidence interval (CI) 0.86 to 1.56), but clinically important differences could not be confidently ruled out. No trials compared anterior repair with suburethral sling operations or laparoscopic colposuspensions, or compared alternative vaginal operations.Anterior vaginal repair was less effective than open abdominal retropubic suspension based on patient-reported cure rates in eight trials both in the medium term (failure rate within one to five years after anterior repair 97/259 (38%) versus 57/327 (17%); RR 2.29, 95% confidence Interval (CI) 1.70 to 3.08) and in the long term (after five years, (49/128 (38%) versus 31/145 (21%); RR 2.02, 95% CI 1.36 to 3.01). There was evidence from three of these trials that this was reflected in a need for more repeat operations for incontinence (25/107 (23%) versus 4/164 (2%); RR 8.87, 95% CI 3.28 to 23.94). These findings held, irrespective of the co-existence of prolapse (pelvic relaxation). Although fewer women had a prolapse after anterior repair (RR 0.24, 95% CI 0.12 to 0.47), later prolapse operation appeared to be equally common after vaginal (3%) or abdominal (4%) operation.In respect of the type of open abdominal retropubic suspension, most data related to comparisons of anterior vaginal repair with Burch colposuspension. The few data describing comparison of anterior repair with the Marshall-Marchetti-Krantz procedure were consistent with those for Burch colposuspension.

AUTHORS' CONCLUSIONS

There were not enough data to allow comparison of anterior vaginal repair with physical therapy or needle suspension for primary urinary stress incontinence in women. Open abdominal retropubic suspension appeared to be better than anterior vaginal repair judged on subjective cure rates in eight trials, even in women who had prolapse in addition to stress incontinence (six trials). The need for repeat incontinence surgery was also less after the abdominal operation. However, there was not enough information about postoperative complications and morbidity.A Brief Economic Commentary (BEC) identified one study suggesting that vaginoplasty may be more cost-effective compared with tension-free vaginal tape (TVT-O).

Outcome of vaginal mesh reconstructive surgery in multiparous compared with grand multiparous women: Retrospective long-term follow-up

We aimed to compare the long-term surgical outcome and complications of multiparous and grand multiparous women undergoing reconstructive surgery with vaginal mesh implants for repair of pelvic organ prolapse. This retrospective, long-term follow-up (28.17±20.7 months) comprised 113 women who underwent surgical reconstructive surgery with vaginal polypropylene mesh in a high parity rate population medical center. The women were divided into 2 groups (multiparous and grand multiparous) and each group was evaluated for objective and subjective surgical outcome. Patient demographics and surgical data were retrieved from electronic medical records. Outcome measure included POP-Q exam as objective outcome and validated Pelvic Floor Distress Inventory questionnaire (PFDI) to assess subjective outcome. Average age of patients was 62±7.9 (range 42–83) years. Average parity was 5.6±3.1 (range 1–14). There were 54 (47.7%) multiparous women and 59 (52.3%) grand multiparous women. The grand multiparous women were younger than the multiparous women and had a significantly higher degree of prolapse. At the last follow-up, the only significant difference was related to symptoms of an overactive bladder. In conclusion, long-term follow-up demonstrates that vaginal mesh surgery in grand multiparous women offers anatomical and subjective cure rates comparable to multiparous women.

Textile properties of synthetic prolapse mesh in response to uniaxial loading

BACKGROUND

Although synthetic mesh is associated with superior anatomic outcomes for the repair of pelvic organ prolapse, the benefits of mesh have been questioned because of the relatively high complication rates. To date, the mechanisms that result in such complications are poorly understood, yet the textile characteristics of mesh products are believed to play an important role. Interestingly, the pore diameter of synthetic mesh has been shown to impact the host response after hernia repair greatly, and such findings have served as design criteria for prolapse meshes, with larger pores viewed as more favorable. Although pore size and porosity are well-characterized before implantation, the changes in these textile properties after implantation are unclear; the application of mechanical forces has the potential to greatly alter pore geometries in vivo. Understanding the impact of mechanical loading on the textile properties of mesh is essential for the development of more effective devices for prolapse repair.

OBJECTIVE

The objective of this study was to determine the effect of tensile loading and pore orientation on mesh porosity and pore dimensions.

STUDY DESIGN

In this study, the porosity and pore diameter of 4 currently available prolapse meshes were examined in response to uniaxial tensile loads of 0.1, 5, and 10 N while mimicking clinical loading conditions. The textile properties were compared with those observed for the unloaded mesh. Meshes included Gynemesh PS (Ethicon, Somerville, NJ), UltraPro (Artisyn; Ethicon), Restorelle (Coloplast, Minneapolis, MN), and Alyte Y-mesh (Bard, Covington, GA). In addition to the various pore geometries, 3 orientations of Restorelle (0-, 5-, 45-degree offset) and 2 orientations of UltraPro (0-, 90-degree offset) were examined.

RESULTS

In response to uniaxial loading, both porosity and pore diameter dramatically decreased for most mesh products. The application of 5 N led to reductions in porosity for nearly all groups, with values decreasing by as much as 87% (P < .05). On loading to 10 N of force, nearly all mesh products that were tested were found to have porosities that approached 0% and 0 pores with diameters >1 mm.

CONCLUSION

In this study, it was shown that the pore size of current prolapse meshes dramatically decreases in response to mechanical loading. These findings suggest that prolapse meshes, which are more likely to experience tensile forces in vivo relative to hernia repair meshes, have pores that are unfavorable for tissue integration after surgical tensioning and/or loading in urogynecologic surgeries. Such decreases in pore geometry support the hypothesis that regional increases in the concentration of mesh leads to an enhanced local foreign body response. Although pore deformation in transvaginal meshes requires further characterization, the findings presented here provide a mechanical understanding that can be used to recognize potential areas of concern for complex mesh geometries. Understanding mesh mechanics in response to surgical and in vivo loading conditions may provide improved design criteria for mesh and a refinement of surgical techniques, ultimately leading to better patient outcomes.

Determination of a Central Avascular Triangle within the Obturator Foramen: A Radioanatomic Study

PURPOSE

To map the vascular anatomy of the obturator foramen using fixed anatomic landmarks.

METHOD

Twenty obturator regions were dissected in 10 fresh female cadavers after vascular blue dye injection in five cadavers (50%). Furthermore, 104 obturator regions were reconstructed by angiotomodensitometry from 52 women under investigation for suspected arterial disease. The anatomy of the obturator region was mapped by measuring the distance of vascular structures from the middle of the two branches of the ischiopubic bone, which were used as fixed landmarks.

RESULTS

The bifurcation of the obturator artery was at a mean (SD) distance of 30.0 mm (4.5) from the middle of the ischiopubic branch (MISP). The anterior branch of the obturator vessels was 15.2 mm (10.1) from the MISP. The posterior branch of the obturator vessels was 5.5 mm (4.0) and 23.6 mm (8.7) from the middle of the outer edge of the obturator foramen (MOE) and the MISP, respectively. Using 5° and 95° percentiles of these measurements we defined a central avascular triangle.

CONCLUSIONS

Our data show that, beyond inter-individual variations, a central triangular avascular area can be identified in the obturator foramen between the posterior and anterior obturator artery using fixed landmarks.

One-year prospective comparison of vaginal pessaries and surgery for pelvic organ prolapse using the validated ICIQ-VS and ICIQ-UI (SF) questionnaires

INTRODUCTION AND HYPOTHESIS

Vaginal pessaries, pelvic floor exercises and surgery are treatment options for women with symptomatic pelvic organ prolapse (POP). The aim of this study was to compare the outcomes of pessaries and surgery in women with symptomatic POP using the validated International Consultation on Incontinence Questionnaire-Vaginal Symptoms (ICIQ-VS) and Urinary Incontinence (ICIQ-UI) Short Form (SF).

METHODS

Women attending the Urogynecology clinics with symptomatic POP were recruited. All women were treated using either a vaginal pessary or surgery. Outcomes were evaluated and then compared at 1 year using the validated ICIQ-VS and ICIQ-UI (SF) questionnaires.

RESULTS

A total of 287 women with symptomatic prolapse were recruited. 269 women completed the questionnaires at baseline and 183 at 1 year. At 1 year, improvement was noted in quality of life (QOL), frequency of urinary leak and vaginal symptoms in both groups except for the symptom of vaginal soreness in the pessary group and the symptom of a tight vagina in the surgery group. However, both these symptoms were not bothersome. Women who underwent surgery demonstrated an improvement in faecal evacuation and sex life. There was an overall statistically significant improvement in vaginal, sex, QOL and urinary symptom scores in both groups. No statistically significant difference was noted between the surgery and the pessary groups.

CONCLUSIONS

Using validated questionnaires 1 year after treatment, women with symptomatic POP report improvement in vaginal, bowel, urinary and quality of life scores when treated with either pessary use or surgery. No statistically significant difference was noted in the two groups.

Tolerance and long-term MRI imaging of gadolinium-modified meshes used in soft organ repair

Background

Synthetic meshes are frequently used to reinforce soft tissues. The aim of this translational study is to evaluate tolerance and long-term MRI visibility of two recently developed Gadolinium-modified meshes in a rat animal model.

Materials and Methods

Gadolinium-poly-ε-caprolactone (Gd-PCL) and Gadolinium-polymethylacrylate (Gd-PMA) modified meshes were implanted in Wistar rats and their tolerance was assessed daily. Inflammation and biocompatibility of the implants were assessed by histology and immunohistochemistry after 30 days post implantation. Implants were visualised by 7T and 3T MRI at day 30 and at day 90. Diffusion of Gadolinium in the tissues of the implanted animals was assessed by Inductively Coupled Plasma Mass Spectrometry.

Results

Overall Gd-PMA coated implants were better tolerated as compared to those coated with Gd-PCL. In fact, Gd-PMA implants were characterised by a high ratio collagen I/III and good vascularisation of the integration tissues. High resolution images of the coated mesh were obtained in vivo with experimental 7T as well as 3T clinical MRI. Mass spectrometry analyses showed that levels of Gadolinium in animals implanted with coated mesh were similar to those of the control group.

Conclusions

Meshes coated with Gd-PMA are better tolerated as compared to those coated with Gd-PCL as no signs of erosion or significant inflammation were detected at 30 days post implantation. Also, Gd-PMA coated meshes were clearly visualised with both 7T and 3T MRI devices. This new technique of mesh optimisation may represent a valuable tool in soft tissue repair and management.

Postoperative pain outcomes after transvaginal mesh revision

INTRODUCTION AND HYPOTHESIS

Although the current literature discusses mesh complications including pain, as well as suggesting different techniques for removing mesh, there is little literature regarding pain outcomes after surgical removal or revision. The purpose of this study is to determine if surgical removal or revision of vaginal mesh improves patient's subjective complaints of pelvic pain associated with original placement of mesh.

METHODS

After obtaining approval from the Vanderbilt University Medical Center Institutional Review Board, a retrospective review of female patients with pain secondary to previous mesh placement who underwent excision or revision of vaginal mesh from January 2000 to August 2012 was performed. Patient age, relevant medical history including menopause status, previous hysterectomy, smoking status, and presence of diabetes, fibromyalgia, interstitial cystitis, and chronic pelvic pain, was obtained. Patients' postoperative pain complaints were assessed.

RESULTS

Of the 481 patients who underwent surgery for mesh revision, removal or urethrolysis, 233 patients met our inclusion criteria. One hundred and sixty-nine patients (73 %) reported that their pain improved, 19 (8 %) reported that their pain worsened, and 45 (19 %) reported that their pain remained unchanged after surgery. Prior history of chronic pelvic pain was associated with increased risk of failure of the procedure to relieve pain (OR 0.28, 95 % CI 0.12-0.64, p = 0.003).

CONCLUSIONS

Excision or revision of vaginal mesh appears to be effective in improving patients' pain symptoms most of the time. Patients with a history of chronic pelvic pain are at an increased risk of no improvement or of worsening pain.

Laparoscopic repair of recurrent lateral enterocele and rectocele

It is difficult to determine what types of procedures should be attempted in patients who have recurrent prolapse. We present a case of recurrent lateral enterocele and rectocele after the patient had undergone multiple surgeries for pelvic organ prolapse (POP), including a vaginal hysterectomy, bladder-neck suspension, anterior colporrhaphy, site-specific rectocele repair, apical mesh implant, iliococcygeus vault suspension, and transobturator suburethral sling procedure. With recurrence, the patient underwent robot-assisted laparoscopic sacral colpopexy, tension-free vaginal tape transobturator sling insertion, rectocele repair, and perineorrhaphy with cystoscopy. She then presented with defecatory outlet obstruction and constipation and subsequently was treated with a stapled transanal rectal resection. The patient returned with continued defecatory dysfunction and a recurrent lateral enterocele and rectocele. The recurrence was treated laparoscopically using a lightweight polypropylene mesh. The postoperative period was uneventful. Two years later, the patient reported decreased defecatory symptoms and no further symptomatic prolapse.

Early results of a novel technique for anterior vaginal wall prolapse repair: anterior vaginal wall darn

BACKGROUND

The aim of this study was to describe the results of a 1-year patient follow-up after anterior vaginal wall darn, a novel technique for the repair of anterior vaginal wall prolapse.

METHODS

Fifty-five patients with anterior vaginal wall prolapse underwent anterior vaginal wall darn. The anterior vaginal wall was detached using sharp and blunt dissection via an incision beginning 1 cm proximal to the external meatus and extending to the vaginal apex. The space between the tissues that attach the lateral vaginal walls to the arcus tendineus fasciae pelvis was then darned. Cough Stress Test, Pelvic Organ Prolapse Quantification, seven-item Incontinence Impact Questionnaire, and six-item Urogenital Distress Inventory scores were performed 1-year postoperatively to evaluate recovery.

RESULTS

One-year postoperatively, all patients were satisfied with the results of the procedure. No patient had vaginal mucosal erosion or any other complication.

CONCLUSIONS

One-year postoperative findings for patients in this series indicate that patients with stage II-III anterior vaginal wall prolapse were successfully treated with the anterior vaginal wall darn technique.

Incidence and lifetime risk of pelvic organ prolapse surgery in Denmark from 1977 to 2009

INTRODUCTION AND HYPOTHESIS

The purpose of the study was to describe the incidence of pelvic organ prolapse (POP) surgeries in Denmark during the last 30 years, age distribution over time, and the lifetime risk of undergoing POP surgery.

METHODS

We carried out a population-based registry study. The setting was the Danish National Patient Registry. The sample consisted of Danish women of all ages undergoing prolapse surgery during the period 1977-2009. Data were retrieved from the Danish National Patient Registry. Prolapse surgery included surgery for any type of genital prolapse including hysterectomy due to prolapse. The main outcome measures were incidence of POP, age distribution over time, and lifetime risk of undergoing POP surgery.

RESULTS

Surgical interventions for POP decreased by 47 % from 1977 (288 procedures/100,000 women) to 1999 (153 procedures/100,000 women). Subsequently, they increased to 75 % of the original incidence rate; in 2008, the incidence of total POP procedures was 201 out of 100,000 women and the incidence of women undergoing POP surgery was 139 out of 100,000 women. During the study period, the age-specific incidence of POP surgeries increased for women over the age of 65-69 years and decreased for women below that age. In 2008, the lifetime risk for an 80-year-old woman of undergoing at least one POP surgery was 18.7 %.

CONCLUSIONS

The incidence of POP surgery varied up to 50 % during the study period. The age distribution changed so that more elderly and less young women had surgery in 2008 compared with 1978. Finally, we found that the lifetime risk of undergoing POP surgery for an 80-year-old was 26.9 % in 1978, 20.5 % in 1988, 17.2 % in 1998, and 18.7 % in 2008.

A Review of Comparison of Complications of Vaginal Hysterectomy with and without Concomitant Surgery for SUI: A 5 Years' Experience at a Tertiary Care Hospital of Pakistan

Objective. The study was performed to review the complications of surgery for POP with or without surgery for SUI. This included the need for second procedure two years after the primary surgery. Study Design. We conducted a retrospective cross-sectional comparative study at the Aga Khan University, Karachi, Pakistan. International Classification of Diseases, 9th revision, Clinical Modification (ICD-9-CM) was used to identify women who underwent vaginal hysterectomy with anterior/posterior repair alone and those with concomitant tension-free vaginal tape surgery for urodynamic stress incontinence. Results. The 28 cases of VH/repair combined with TVT were compared for complications with 430 cases of VH with repair alone. The basic characteristics like age, BMI, and degree of prolapse showed no statistical difference among two groups. The main comorbidities in both groups were hypertension, diabetes, and bronchial asthma. We observed no significant differences in intraoperative and postoperative complications except for cuff abscess, need for medical intervention, and readmission following discharge from hospital, which were higher in cases with vaginal hysterectomy with concomitant TVT. Conclusions. Vaginal hysterectomy is an efficient treatment for uterovaginal prolapse with a swift recovery, short length of hospital stay, and rare serious complications. The addition of surgery for USI does not appear to increase the morbidity.

Efficacy of laparoscopic sacrocervicopexy for apical support of pelvic organ prolapse

Laparoscopic sacrocervicopexy appears to be an effective option for sexually active women with pelvic organ prolapse.

Background and Objectives:

To evaluate the efficacy of laparoscopic sacrocervicopexy for apical support in sexually active patients with pelvic organ prolapse.

Methods:

One-hundred thirty-five women with symptomatic prolapse of the central compartment (Pelvic Organ Prolapse Quantitative [POP-Q] stage 2) underwent laparoscopic sacrocervicopexy. The operating physicians used synthetic mesh to attach the anterior endopelvic fascia to the anterior longitudinal ligament of the sacral promontory with subtotal hysterectomy. Anterior and posterior colporrhaphy was performed when necessary. The patients returned for follow-up examinations 1 month after surgery and then over subsequent years. On follow-up a physician evaluated each patient for the recurrence of genital prolapse and for recurrent or de novo development of urinary or bowel symptoms. We define “surgical failure” as any grade of recurrent prolapse of stage II or more of the POP-Q test. Patients also gave feedback about their satisfaction with the procedure.

Results:

The mean follow-up period was 33 months. The success rate was 98.4% for the central compartment, 94.2% for the anterior compartment, and 99.2% for the posterior compartment. Postoperatively, the percentage of asymptomatic patients (51.6%) increased significantly (P < .01), and we observed a statistically significant reduction (P < .05) of urinary urge incontinence, recurrent cystitis, pelvic pain, dyspareunia, and discomfort. The present study showed 70.5% of patients stated they were very satisfied with the operation and 18.8% stated high satisfaction.

Conclusion:

Laparoscopic sacrocervicopexy is an effective option for sexually active women with pelvic organ prolapse.

Consensus statement AIGO/SICCR diagnosis and treatment of chronic constipation and obstructed defecation (part II: treatment)

The second part of the Consensus Statement of the Italian Association of Hospital Gastroenterologists and Italian Society of Colo-Rectal Surgery reports on the treatment of chronic constipation and obstructed defecation. There is no evidence that increasing fluid intake and physical activity can relieve the symptoms of chronic constipation. Patients with normal-transit constipation should increase their fibre intake through their diet or with commercial fibre. Osmotic laxatives may be effective in patients who do not respond to fibre supplements. Stimulant laxatives should be reserved for patients who do not respond to osmotic laxatives. Controlled trials have shown that serotoninergic enterokinetic agents, such as prucalopride, and prosecretory agents, such as lubiprostone, are effective in the treatment of patients with chronic constipation. Surgery is sometimes necessary. Total colectomy with ileorectostomy may be considered in patients with slow-transit constipation and inertia coli who are resistant to medical therapy and who do not have defecatory disorders, generalised motility disorders or psychological disorders. Randomised controlled trials have established the efficacy of rehabilitative treatment in dys-synergic defecation. Many surgical procedures may be used to treat obstructed defecation in patients with acquired anatomical defects, but none is considered to be the gold standard. Surgery should be reserved for selected patients with an impaired quality of life. Obstructed defecation is often associated with pelvic organ prolapse. Surgery with the placement of prostheses is replacing fascial surgery in the treatment of pelvic organ prolapse, but the efficacy and safety of such procedures have not yet been established.

A novel technique for anterior vaginal wall prolapse repair: anterior vaginal wall darn

AIM

The aim of this study is to introduce a new technique, anterior vaginal wall darn (AVWD), which has not been used before to repair the anterior vaginal wall prolapse, a common problem among women.

MATERIALS AND METHODS

Forty-five women suffering from anterior vaginal wall prolapse were operated on with a new technique. The anterior vaginal wall was detached by sharp and blunt dissection via an incision beginning from the 1 cm proximal aspect of the external meatus extending to the vaginal apex, and the space between the tissues that attach the lateral walls of the vagina to the arcus tendineus fascia pelvis (ATFP) was then darned. Preoperation and early postoperation evaluations of the patients were conducted and summarized.

RESULTS

Data were collected six months after operation. Cough stress test (CST), Pelvic Organ Prolapse Quantification (POP-Q) evaluation, Incontinence Impact Questionnaire (IIQ-7), and Urogenital Distress Inventory (UDI-6) scores indicated recovery. According to the early postoperation results, all patients were satisfied with the operation. No vaginal mucosal erosion or any other complications were detected.

CONCLUSION

In this initial series, our short-term results suggested that patients with grade II-III anterior vaginal wall prolapsus might be treated successfully with the AVWD method.

Laparoscopic colposuspension to the Cooper's ligament after hysterectomy for uterovaginal prolapse

AIM

The goal of this study was to evaluate the long-term outcomes of laparoscopic colposuspension to the Cooper's ligament after hysterectomy for uterovaginal prolapse.

MATERIAL AND METHODS

We performed chart reviews of 43 patients with uterovaginal prolapse who underwent laparoscopic colposuspension to the Cooper's ligament after hysterectomy at Daejeon St. Mary's Hospital, Catholic University of Korea from 2003 to 2009. These patients exhibited grade 3 (29 patients) or grade 4 (14 patients) uterovaginal prolapse.

RESULTS

The mean age was 63.2 years (range, 39-76). The mean follow-up period was 44.2 months (95% CI, 36.8-51.5). Forty-three patients showed no sign or recurrence of prolapse. Postoperative complications were tolerable and curable. Urinary frequency (2 patients, 4.7%), voiding difficulty (2 patients, 4.7%), nocturia (1 patient, 2.3%) and vaginal spotting (1 patient, 2.3%) were reported.

CONCLUSION

Laparoscopic colposuspension using Cooper's ligament after hysterectomy could be an effective surgical option for the treatment of uterovaginal prolapse.

Strength of round and uterosacral ligaments: a biomechanical study

PURPOSE

To investigate the tensile biomechanical properties of round and uterosacral ligaments.

METHODS

Tissue samples were obtained from 15 female cadavers without pelvic organ prolapse. Uniaxial tensile tests were performed to obtain stiffness and maximum stress of round and uterosacral ligaments. Correlations were calculated using the Pearson correlation coefficient. Statistical differences between groups were tested using Student's paired and unpaired t test.

RESULTS

There was a great variability in the measurements of stiffness and maximum stress in pelvic ligaments. The round ligaments demonstrated stiffness of 9.1 ± 1.6 MPa (mean ± SEM) (ranging from 2 to 25.6 MPa) and maximum stress of 4.3 ± 0.7 MPa (ranging from 1.2 to 11.5 MPa). The stiffness of the uterosacral ligaments was 14.1 ± 1.4 MPa (ranging from 5.7 to 26.1 MPa) with maximum stress of 6.3 ± 0.8 MPa (ranging from 2.2 to 11.9 MPa). There was a strong positive correlation between stiffness and maximum stress in female pelvic ligaments (ρ = 0.851; p < 0.001). The uterosacral ligaments demonstrated higher stiffness and maximum stress compared to the round ligaments (p = 0.006 and p = 0.034; respectively). Age, body mass index and menopausal status were not associated with the biomechanical proprieties of round and uterosacral ligaments. Nulliparous women had lower uterosacral stiffness (15.5 ± 1.3 vs. 10 ± 1.8 MPa; p = 0.033) and maximum stress (8.2 ± 0.9 vs. 4.2 ± 1.1 MPa; p = 0.028) compared to parous women.

CONCLUSION

The uterosacral ligaments are significantly more resistant than round ligaments. Parturition seems to enhance the stiffness and maximum stress of the ligaments.

A randomised controlled trial of abdominal versus laparoscopic sacrocolpopexy for the treatment of post-hysterectomy vaginal vault prolapse: LAS study

INTRODUCTION AND HYPOTHESIS

This prospective multi-centre true two-sided equivalence trial was designed to test the clinical equivalence of open (ASCP) and laparoscopic (LSCP) sacrocolpopexy using objective and subjective outcomes

METHODS

The study was carried out in three urogynaecology units in England, UK and the patient population consisted of women referred with symptomatic and bothersome post-hysterectomy vaginal vault prolapse at least 1 cm above or beyond the hymeneal remnants. The interventions were either abdominal or laparoscopic sacrocolpopexy following randomisation to one of the types of surgery.

RESULTS

For the primary outcome (point C on the POP-Q) the results at 1 year were -6.63 cm for the open ASCP and -6.67 cm for the LSCP respectively. Subjective outcomes at 1 year showed that 90% of the ASCP group and 80% of the LSCP group were "much better". There were improvements with regard to blood loss, haemoglobin and shorter length of stay in the LSCP group compared with the ASCP group.

CONCLUSION

This fully powered randomised controlled trial comparing open and laparoscopic sacrocolpopexy has shown clinical equivalence.

Comparison of Long-term Clinical Outcomes according to the Change in the Rectocele Depth between Transanal and Transvaginal Repairs for a Symptomatic Rectocele

Purpose

This study was aimed to compare the results of a transanal repair with those of a transvaginal levatorplasty and to determine the long-term clinical outcomes according to the change in the depth of the rectocele after the procedure.

Methods

Of 50 women who underwent a rectocele repair from March 2005 to February 2007, 26 women (group A) received a transanal repair, and 24 (group B) received a transvaginal repair with or without levatorplasty. At 12 months after the procedures, 45 (group A/B, 22/23 women) among the 50 women completed physiologic studies, including anal manometry and defecography, and clinical-outcome measurements. The variations of the clinical outcomes with changes in the depth of the rectocele were also evaluated in 42 women (group A/B, 20/22) at the median follow-up of 50 months.

Results

On the defecographic findings, the postoperative depth of the rectocele decreased significantly in both groups (group A vs. B, 1.91 ± 0.20 vs. 2.25 ± 0.46, P = 0.040). At 12 months after surgery, 17 women in each group (group A/B, 77/75%) reported improvement of their symptoms. However, only 11 and 13 women (group A/B, 55/59%) of groups A and B, respectively, maintained their improvement at the median follow-up of 50 months. Better results were reported in patients with a greater change in the depth of their rectocele (≥4 cm) after the procedure (P = 0.001)

Conclusion

In both procedures, clinical outcomes might become progressively worse as the length of the follow-up is increased.

Magnetic resonance imaging of abdominal versus vaginal prolapse surgery with mesh

INTRODUCTION AND HYPOTHESIS

We compared two surgical approaches in patients with symptomatic prolapse of the vaginal apex with normal controls by analyzing pelvic landmark relationships measured using magnetic resonance imaging (MRI) before and after surgery.

METHODS

In this prospective multicenter pilot study involving 16 participants, nulliparous controls (n = 6) were compared with ten parous (3.0 ± 1.0) women with uterine apical prolapse equal to or greater than stage 2. Group A (n = 5) underwent abdominal sacral colpopexy with monofilament polypropylene mesh and group B (n = 5) with vaginal mesh kit repair (Total ProLift). Subtotal hysterectomy was performed in all group A and no group B women. All patients underwent preoperative and 3-month postoperative Pelvic Organ Prolapse Quantification (POP-Q) and dynamic MRI. Comparison of MRI pelvic angles and distances was performed and analyzed by Mann-Whitney rank sum test and chi-square test.

RESULTS

Vaginal apical support is similar at 3 months for abdominal sacral colpopexy (ASCP) and ProLift by POP-Q examination and MRI analysis. In both treatment groups, the postoperative POP-Q point C and MRI parameters were similar to nulliparous controls at 3 months.

CONCLUSIONS

Anatomic outcomes for ASCP compared with ProLift were similar at 3 months in terms of vaginal apical support by POP-Q and MRI analysis. Continued comparative analysis of postoperative support with objective imaging seems warranted.

Subjective and objective results of anterior vaginal wall repair in an outpatient clinic: a 5-year follow-up

INTRODUCTION AND HYPOTHESIS

This prospective follow-up study evaluates long-term subjective and objective outcome of conventional anterior vaginal wall repair in an outpatient setting.

METHODS

Eighty-two women were operated. At 5-year follow-up anatomical results were evaluated by clinical examination. Furthermore, the women filled in a validated symptom and quality of life questionnaire.

RESULTS

Seventy (85%) women attended the follow-up visit. Eleven percent of these had been reoperated for anterior vaginal wall prolapse and was considered a separate group in the analysis. Thirty-four percent had no pelvic organ prolapse (POP). Twenty-nine percent had stage 1 POP whereas 24% had stage 2 and 2% stage 3 at follow-up. Seventy-eight percent of the women had no bulge symptoms, and 73%of the women considered their condition improved.

CONCLUSIONS

At 5-year follow-up 78 % was relieved from their bulge symptoms by an operation using local anesthesia. Eleven percent of the women had been reoperated.

Changing trends of surgical approaches for uterine prolapse: an 11-year population-based nationwide descriptive study

INTRODUCTION AND HYPOTHESIS

The interest of uterus-preserving surgery has been growing. Based on a nationwide database, we examined surgical procedures for uterine prolapse in Taiwan during the study period of 1997-2007, a total of 11 years.

METHODS

The operations, either uterine suspension or hysterectomy, due to the diagnosis of uterine prolapse were indentified into the study. Data on several parameters were collected for analysis, i.e., the surgical type, patient factors (age and concomitant anti-incontinence surgery), surgeon factors (age and gender), and hospital factors (accreditation level and ownership). Data of this study were obtained from the inpatient expenditures by admission files of the National Health Insurance Research Database (NHIRD). The NHIRD was established by the National Health Research Institute with the aim of promoting research into current and emerging medical issues in Taiwan.

RESULTS

In total, 31,038 operations were identified for this study. There was a trend for increased use of uterine suspension with uterine preservation during the latter years, evidenced by joinpoint regression analyses. More women who were younger (<50 years) or had concomitant anti-incontinence surgery received uterine suspension. Younger surgeons (<50 years) and male surgeons tended to perform more uterine suspensions. As for hospital accreditation, more uterine suspension surgeries were performed in regional hospitals, followed by local hospitals and medical centers. As for hospital ownership, more uterine suspension surgeries were performed in private hospitals, followed by not-for-profit and government-owned hospitals.

CONCLUSIONS

There has been a considerable change in the surgical approach for uterine prolapse in Taiwan over the past 11 years. Patient age and concomitant anti-incontinence surgery, surgeon age and gender, and hospital accreditation and ownership may correlate with the choice of surgery for women with uterine prolapse.

Natural orifice vaginal sacrocolpopexy (NOVaS): a cadaver feasibility study

INTRODUCTION AND HYPOTHESIS

The primary objective was to determine the feasibility of a vaginal approach to sacrocolpopexy using a cadaver model. Secondary objectives were to measure the distance from the vaginal introitus to the sacrum and distances of the sacral fixation elements to other vital structures.

METHODS

Fourteen fresh-frozen cadavers were used. Specialized instruments were developed to optimize visualization and facilitate performance of the procedure.

RESULTS

Five cadavers had a transperineal approach (an approach found unfeasible), and eight of the remaining nine had complete or partial completion of the transvaginal approach. The mean distance from the introitus to the promontory was 14.6 cm (12-16.5 cm). The mean distance from the sacral fixation elements to the aorta was 5.2 cm; common iliac artery, 3.5 cm; internal iliac artery, 3.25 cm; middle sacral artery, 1.75 cm, and ureters, 3.5 cm. The position of the sacral fixation elements was consistently at the level of S1-2.

CONCLUSION

Vaginal sacrocolpopexy is feasible in a cadaver model.

Case study: a patient-clinician collaboration that identified and prioritized evidence gaps and stimulated research development

OBJECTIVE

To assess the effect of a research prioritization partnership that aimed to influence the research agenda relating to urinary incontinence (UI).

STUDY DESIGN AND SETTING

Research often neglects important gaps in existing evidence so that decisions must be made about treatments without reliable evidence of their effectiveness. In 2007-2009, a United Kingdom partnership of eight patient and 13 clinician organizations identified and prioritized gaps in the evidence that affect everyday decisions about treatment of UI. The top 10 prioritized research questions were published and reported to research funders in 2009. A year later, new research or funding applications relating to the prioritized topics were identified through reviews of research databases and consultation with funding organizations, elements of the research community, and organizations that participated in the partnership.

RESULTS

Since dissemination of the prioritized topics, five studies are known to have been funded, three in development; five new systematic reviews are under way, one is being updated; five questions are under consideration by a national research commissioning body.

CONCLUSION

The partnership successfully developed and used a methodology for identification and prioritization of research needs through patient-clinician consensus. Prioritization through consensus can be effective in informing the development of clinically useful research.

Supracervical robotic-assisted laparoscopic sacrocolpopexy for pelvic organ prolapse

Supracervical robotic-assisted laparoscopic sacrocolpopexy was found to be an effective repair of apical vaginal defects in patients with pelvic organ prolapse who had not undergone previous hysterectomy.

Background:

Supracervical robotic-assisted laparoscopic sacrocolpopexy (SRALS) is a new surgical treatment for pelvic organ prolapse that secures the cervical remnant to the sacral promontory. We present our initial experience with SRALS in the same setting as supracervical robotic-assisted hysterectomy (SRAH).

Methods:

Women with vaginal vault prolapse and significant apical defects as defined by a Baden-Walker score of ≥3 who had not undergone hysterectomy were offered SRALS in combination with SRAH. A chart review was performed to analyze operative and perioperative data. Outcome data also included patients who underwent robotic-assisted laparoscopic sacrocolpopexy (RALS) without any other procedure.

Results:

Thirty-three patients underwent RALS, including 12 patients who underwent SRALS. All SRALS were performed following SRAH in the same setting. The mean follow-up for the RALS and SRALS patients was 38.4 months and 20.7 months, respectively. One patient in the RALS group had an apical recurrence. There were no recurrences in the SRALS group.

Conclusions:

SRALS is effective for repair of apical vaginal defects in patients with significant pelvic organ prolapse who have not undergone previous hysterectomy. Complications are few and recurrences rare in short- and medium-term follow-up. Greater follow-up and numbers are needed to further establish the role of this procedure.

Uterus preservation in pelvic organ prolapse surgery

Attitudes to sexuality and the psychological value of reproductive organs have changed in Western countries over the last few decades. Nevertheless, repair of pelvic support defects with concomitant hysterectomy is still considered the standard treatment for pelvic organ prolapse. Over the last 10 years, however, interest has been growing in uterus-sparing surgery, which can be divided into vaginal, abdominal, and laparoscopic procedures. The majority of studies on uterus-sparing surgery, with the exception of abdominal techniques, report few cases with short follow-up. Sacrospinous hysteropexy is the most studied vaginal technique for uterus preservation and favorable results have been demonstrated, although the majority of studies are flawed by selection and information bias, short follow-up and lack of adequate control groups. Abdominal and laparoscopic procedures are promising, providing similar functional and anatomical results to hysterectomy and sacrocolpopexy. Consensus is growing that the uterus can be preserved at the time of pelvic reconstructive surgery in appropriately selected women who desire it. The results of comparison trials and prospective studies confirm that uterus-sparing surgery is feasible and is associated with similar outcomes to hysterectomy, as well as shorter operating times. Surgeons should be ready to respond to the wishes of female patients who want to preserve vaginal function and the uterus.

Sacrocolpopexy using xenogenic acellular collagen in patients at increased risk for graft-related complications

AIMS

We studied the long-term anatomical and functional outcome following sacrocolpopexy for apical vaginal prolapse using xenogenic grafts in a population at increased risk for graft-related complications (GRCs).

METHODS

Twenty-two consecutive patients with symptomatic apical prolapse were scheduled for laparoscopic sacrocolpopexy (LSC) with porcine grafts because they were presumed to be at risk for GRC, because of pre-existing vaginal ulcerations (n = 4), concomitant vaginal prolapse repair (n = 15), total hysterectomy (n = 1), or intra-operative abdominal contamination due to accidental laceration of the vagina, bowel perforation (n = 1) or the presence of infection (n = 1). Either small intestinal submucosa (n = 8) or dermal collagen (n = 14) was used. Outcome measures were GRCs, anatomical cure (<or=Stage I at any compartment), subjective cure, impact on bowel, bladder, and sexual function measured by a standardized interview.

RESULTS

At study closure 20 (91%) patients were available for functional evaluation and 16 (73%) for anatomical evaluation at a mean follow-up period of 27.4 months. The GRC rate was 25% (n = 4) prompting reintervention in half, and including two patients with spondylodiscitis. The anatomical cure rate was 31.5%. Failures at the vault, anterior, and posterior compartments occurred in, respectively, 31%, 18.8%, and 50% of patients. The subjective cure rate was 60% and three patients (15%) underwent redo-LSC.

CONCLUSION

The strategy of using xenografts in patients at risk for GRC, did not prevent these to occur and was associated with a high anatomical and functional failure rate as well as reoperation rate.

Evaluation of the introduction of robotic technology on route of hysterectomy and complications in the first year of use

OBJECTIVE

We sought to determine the differential rates and complications of hysterectomy type in the year prior to and following the introduction of robotic technology.

STUDY DESIGN

This was a retrospective chart review of 461 hysterectomies performed from July 2007 through June 2008 (period 1) and July 2008 through June 2009 (period 2) at Virginia Commonwealth University Medical Center.

RESULTS

In all, 199 vs 262 hysterectomies were performed in periods 1 and 2: open, 52.3% vs 43.1%; laparoscopic, 18.1% vs 8.0%; robotic, 2.5% vs 24.8%; and vaginal, 27.4% vs 24.1%, respectively. The increase in robotic hysterectomies in period 2 was associated only with a decline in laparoscopic hysterectomy (P < .0001). Major morbidity by route was 23.04% open, 11/1% vaginal, 7.02% laparoscopic, and 4.29% robotic (P < .0001).

CONCLUSION

Route of hysterectomy changed significantly after the introduction of robotic technology primarily due to a change in management of pelvic organ prolapse. Open hysterectomy was associated with significantly higher complication rates.

"Inside-out" transobturator tension-free vaginal tape for management of occult stress urinary incontinence in women undergoing pelvic organ prolapse repair

OBJECTIVES

To assess the safety and effectiveness of the "inside-out" transobturator tension-free vaginal tape procedure for the management of occult stress urinary incontinence (SUI) in clinically continent women undergoing prolapse repair.

METHODS

A total of 117 consecutive continent women (mean age and parity 66.8 ± 9.9 years and 3.2 ± 1.5, respectively) with significant pelvic organ prolapse and urodynamically confirmed occult SUI were enrolled in the present study. Surgical intervention included transvaginal prolapse repair and concomitant prophylactic transobturator tension-free vaginal tape. The main outcome measures were procedure-related complications, early and late postoperative morbidity, postoperative urodynamic SUI, persistent or de novo overactive bladder, and bladder outlet obstruction.

RESULTS

No cases of significant blood loss, hematoma formation, or bladder injury occurred. Of the 117 patients, 6 (5.1%) had immediate postoperative voiding difficulties necessitating catheterization for >2 days. Late postoperative morbidity was assessed in 110 patients with ≥3 months of follow-up (mean 27.2 ± 17.7). Of these 110 patients, 7 (6.4%) had protracted postoperative thigh pain with spontaneous resolution within 1-3 months, and 7 (6.4%) had developed recurrent urinary tract infections. No cases of vaginal erosion developed. The functional outcome analysis was restricted to 92 patients with ≥12 months of follow-up (mean 31 ± 16). Of the 92 patients, 13 (14%) were found to have urodynamic SUI. However only 2 patients (2.2%) were symptomatic for a subjective and objective cure rate of 97.8% and 86%, respectively. Of the 34 patients who had had overactive bladder preoperatively, 22 (64.7%) had persisting symptoms postoperatively. An additional 4 patients (6.9%) had developed de novo overactive bladder symptoms, and 1 patient had bladder outlet obstruction.

CONCLUSIONS

The prophylactic transobturator tension-free vaginal tape procedure is both effective and safe in patients with occult SUI undergoing prolapse repair.
