Posterior vaginal compartment repairs: Where are the main anatomical defects?

Introduction and hypothesis

Traditionally, it has been believed that posterior vaginal compartment prolapse was largely due to defects in the rectovaginal fascia, with surgical repairs concentrating on addressing this defect. We aimed to determine the relative size of defects at the different vaginal levels (I–III) following a large number of posterior vaginal compartment repairs (PRs) to determine whether this traditional viewpoint is still appropriate.

Methods

In a cross-sectional study of 300 consecutive PRs, mostly following prior or concomitant hysterectomy, two sets of markers of posterior compartment prolapse were used to measure anatomical defects at levels I–III: (i) from Pelvic Organ Prolapse Quantification (POP-Q) system points C, Ap, Bp, and genital hiatus (GH), and from Posterior Repair Quantification (PR-Q) perineal gap (PG), posterior vaginal-vault descent (PVVD), midvaginal laxity (MVL)—vault undisplaced, and rectovaginal fascial laxity (RVFL).

Results

The largest defects were found at level I (PVVD: mean 6.0 cm; point C, mean minus 0.9 cm), and level III (PG, mean 2.9 cm; GH, mean 3.7 cm). Level II defects (MVL—vault undisplaced, mean 1.3 cm; RVFL, mean 1.1 cm; points Ap, Bp, both mean 1.0 cm) were relatively small.

Conclusions

This study suggests that the defects found at surgery for posterior vaginal compartment prolapse were more frequent at the vaginal vault (level I) and vaginal introitus (level III) than at midvagina (level II). These findings should have implications for surgical planning.

     

A new rectovaginal fascial plication technique for treatment of rectocele with obstructed defecation: a proof of concept study

Introduction and hypothesis

The aim of this study was to investigate the functional and anatomical outcome after a new rectovaginal fascial plication technique in patients with rectoceles or rectal pockets and obstructed defecation.

Methods

In a prospective study 54 of 87 patients were examined pre- and postoperatively using the Pelvic Organ Prolapse Quantification (POP-Q) system of the International Continence Society (ICS). Bowel and protrusion symptoms as well as quality of life (QOL) were evaluated by a standardized questionnaire. Surgical therapy consisted of a posterior vaginal wall incision in the midline, a dissection of the vaginal epithelium from the underlying rectovaginal fascia while the rectocele was brought under tension by the index finger in the rectum. Under rectal digital control the surgically exposed rectovaginal fascia was sutured in a cranio-caudal fashion with sagittally positioned running absorbable sutures followed by a careful reapproximation of the laterally separated perineal body in the midline.

Results

Obstructed defecation symptoms were cured or improved in 72.2 % [95 % confidence interval (CI) 59.1–82.4]. Anatomical cure rate was 92.1 % (95 % CI 79.2–97.3) and protrusion symptoms were resolved in 73.6 % (95 % CI 58.0–85.0). Of the patients who had intercourse, 5.2 % reported de novo dyspareunia postoperatively; in none of these patients was an anatomical cause found. There were no major intra- or postoperative complications.

Conclusions

Sagittal rectovaginal fascial plication in symptomatic rectoceles or functionally relevant rectal pockets is associated with a satisfactory anatomical and functional cure rate without impacting sexual function.     

Posterior repair quantification (PR-Q) using key anatomical indicators (KAI): preliminary report

Introduction and hypothesis

Posterior vaginal compartment repairs (PR) have traditionally involved a subjective approach. We aim to quantify such repairs using key anatomical indicators (KAI).

Methods

At 50 consecutive PRs: perineal gap (PG); posterior vaginal vault descent (PVVD); mid-vaginal laxity (MVL—vault undisplaced/displaced); and recto-vaginal fascial laxity (RVFL) were measured. The total posterior vaginal length (TPVL) and from POP-Q, TVL, GH, Ap, Bp C, D were also measured. Surgical details deemed appropriate to each repair were recorded.

Results

A mean preoperative PG of 2.5 cm was reduced to 0.0 cm postoperatively by excision (100 % cases) with an average increase of 21.6 % in total vaginal length over that if the repair was commenced at the hymen. There was an average reduction of 25.0 % in the genital hiatus (GH). Mean PVVD was 5.3 cm overall; 6.4 cm for 31 out of 50 (62 %) undergoing sacrospinous colpopexy; 3.5 cm for 19 out of 50 (38 %) with no ligamentous vault fixation. An approximate “cut-off” for PVVD of 5 cm may assist with the differentiation of cases where vault fixation may be desirable. Up to 52 % (1.4/2.7 cm) of preoperative MVL displacement was due to vaginal vault descent. The MVL undisplaced (mean 1.3 cm) may better guide vaginal mucosal trimming. RVFL averaged just 0.8 cm with 22 out of 50 (44 %) RVFL being 0.5 cm or less, and not requiring any RVF plicatory sutures.

Conclusions

It is possible to use KAI to assist the planning and execution of posterior vaginal compartment surgery. The PG, PVVD, MVL, and RVFL can indicate surgical measures in the perineum, vaginal vault, vaginal mucosa, and recto-vaginal space respectively.     

Modeling manual perineal protection during vaginal delivery

Introduction and hypothesis

We compared hands-on manual perineal protection (MPP) and hands-off delivery techniques using the basic principles of mechanics and assessed the tension of perineal structures using a novel biomechanical model of the perineum. We also measured the effect of the thumb and index finger of the accoucheur’s dominant-posterior hand on perineal tissue tension when a modified Viennese method of MPP is performed.

Methods

Hands-off and two variations of hands-on manual perineal protection during vaginal delivery were simulated using a biomechanical model, with the main outcome measure being strain/tension throughout the perineal body during vaginal delivery.

Results

Stress distribution with the hands-on model shows that when using MPP, the value of highest stress was decreased by 39 % (model B) and by 30 % (model C) compared with the hands-off model A. On the cross section there is a significant decrease in areas of equal tension throughout the perineal body in both hands-on models. Simulation of the modified Viennese MPP significantly reduces the maximum tension on the inner surface of the perineum measured at intervals of 2 mm from the posterior fourchette.

Conclusions

In a biomechanical assessment with a finite element model of vaginal delivery, appropriate application of the thumb and index finger of the accoucheur’s dominant-posterior hand to the surface of the perineum during the second stage of delivery significantly reduces tissue tension throughout the entire thickness of the perineum; thus, this intervention might help reduce obstetric perineal trauma.     

“Triangle of safety”: anatomic considerations in transvaginal natural orifice surgery

Background

The introduction of transvaginal (TV) natural orifice transluminal endoscopic surgery (NOTES) brings the loss of traditionally used cutaneous landmarks for safe peritoneal access. This video describes the use of landmarks within the posterior vaginal fornix to define a “triangle of safety” wherein the peritoneal cavity can be accessed while minimizing the risk of injury to surrounding structures.

Methods

The triangle of safety is best identified in the following way. The cervix and posterior fornix are visualized. Then an imaginary clock located at the base of the cervix is envisioned. The superior two corners of the triangle are represented by the 4 and 8 o’clock positions on this imaginary clock. Sometimes the cervix needs to be grasped and elevated anteriorly so that the inferior apex of the triangle delineated by the center of the rectovaginal fold is better visualized.

Results

During hybrid TV NOTES, the rectovaginal pouch of Douglas is visualized from the umbilicus, and the vaginal port can then be safely passed through the center of the triangle. It is important that the vaginal port should be angled upward, aiming toward the umbilicus to avoid injury to the rectum. During pure TV NOTES, the incision is made with electrocautery from the 5 o’clock position to the 7 o’clock position within the triangle. The peritoneum is sharply entered, and the colpotomy is dilated with the surgeons’ fingers.

Conclusions

The triangle of safety defines a set of landmarks between the base of the cervix and the rectovaginal fold. It allows for a safe TV access for hybrid and pure TV NOTES while minimizing the risk of injury to surrounding structures.     

Measuring the impact of a posterior compartment procedure on symptoms of obstructed defecation and posterior vaginal compartment anatomy

Introduction and hypothesis

We hypothesized that there would be a significant difference in changes in obstructed defecation symptoms and posterior compartment prolapse between women who underwent posterior vaginal wall prolapse repair (PR) and those who did not.

Methods

This was a two-site prospective cohort study of women undergoing prolapse or incontinence surgery in which a PR was, or was not, performed at the discretion of the surgeon. Women were assessed using validated obstructed defecation questionnaires and standardized examination measures (including POP-Q, measurement of transverse gh, and assessment for a rectovaginal pocket and laxity) prior to pelvic surgery and 12 weeks after surgery.

Results

Of 68 women who underwent surgery, 43 had PR. The PR group had higher obstructed defecation symptoms and greater posterior compartment prolapse at baseline. At 12 weeks, obstructed defecation symptoms had improved significantly more in the PR group than in the no PR group (all p?<?0.03). Anatomic outcomes showed greater improvement in point Bp in the PR group (?3.4 vs. ?0.7 no PR, p?<?0.001) and resolution of the rectovaginal pocket (86 % vs. 42 %, p?=?0.002). There were no significant changes in obstructed defecation symptoms or anatomic outcomes from baseline in the no PR group, while the PR group showed significantly improved obstructed defecation symptoms and anatomic outcomes after repair (p?<?0.001 for both).

Conclusions

Significant improvements in obstructed defecation symptoms and posterior compartment prolapse were seen after PR, but not in women who did not receive PR. Obstructed defecation symptoms, Bp and rectovaginal pocket were the measures best able to demonstrate improvement after PR. We recommend the use of these measures to assess the impact of surgery in the posterior compartment.

     

Surgery for posterior vaginal wall prolapse

Introduction and hypothesis

The aim was to review the safety and efficacy of surgery for posterior vaginal wall prolapse.

Methods

Every 4 years and as part of the Fifth International Collaboration on Incontinence we reviewed the English-language scientific literature after searching PubMed, Medline, Cochrane library and Cochrane database of systematic reviews, published up to January 2012. Publications were classified as level 1 evidence (randomised controlled trials [RCT] or systematic reviews), level 2 (poor quality RCT, prospective cohort studies), level 3 (case series or retrospective studies) and level 4 (case reports). The highest level of evidence was utilised by the committee to make evidence-based recommendations based upon the Oxford grading system. Grade A recommendation usually depends on consistent level 1 evidence. Grade B recommendation usually depends on consistent level 2 and/or 3 studies, or “majority evidence” from RCTs. Grade C recommendation usually depends on level 4 studies or “majority evidence? from level 2/3 studies or Delphi processed expert opinion. Grade D “no recommendation possible” would be used where the evidence is inadequate or conflicting and when expert opinion is delivered without a formal analytical process, such as by Delphi.

Results

Level 1 and 2 evidence suggest that midline plication posterior repair without levatorplasty might have superior objective outcomes compared with site-specific posterior reopair (grade B). Higher dyspareunia rates are reported when levatorplasty is employed (grade C). The transvaginal approach is superior to the transanal approach for repair of posterior wall prolapse (grade A). To date, no studies have shown any benefit of mesh overlay or augmentation of a suture repair for posterior vaginal wall prolapse (grade B). While modified abdominal sacrocolpopexy results have been reported, data on how these results would compare with traditional transvaginal repair of posterior vaginal wall prolapse are lacking.

Conclusion

Midline fascial plication without levatorplasty is the procedure of choice for posterior compartment prolapse. No evidence supports the use of polypropylene mesh or biological graft in posterior vaginal compartment prolapse surgery.     

The role of thumb and index finger placement in manual perineal protection

Introduction and hypothesis

Comparison of the modifications of the Viennese method of manual perineal protection (VMPP) and hands-off delivery techniques by applying basic principles of mechanics with assessments of tensions within perineal structures using a novel biomechanical model of the perineum. Evaluation of the role of the precise placements of the accoucheur’s posterior (dominant) thumb and index finger in perineal tissue tension when performing a modified Viennese method of MPP.

Methods

We carried out an experimental study on a biomechanical model of the perineum at NTIS (New Technologies for Information Society, Pilsen, Czech Republic). Hands-off and 38 variations of VMPP were simulated during vaginal delivery with the finite element model imitating a clinical lithotomy position.

Results

The main outcome measures were quantity and extent of strain/tension throughout the perineal body during vaginal delivery. Stress distribution between modifications of VMPP showed a wide variation in peak perineal tension from 72 to 102 % compared with 100 % for the “hands-off” technique. Extent of reduction depended on the extent of finger movement across a horizontal, transverse x-axis, and on final finger position on a vertical, antero-posterior y-axis. The most effective modification of VMPP was initial position of fingers 12 cm apart (x?=?±6) on the x-axis, 2 cm anteriorly from the posterior fourchette (y?=?+2) on the y-axis with 1cm movement of both finger and thumb toward the midline on the x-axis (Δx?=?1) with no movement on the y-axis (Δy?=?0).

Conclusions

In a biomechanical assessment with simulation of vaginal delivery, exact placement of fingertips on the perineal skin, together with their co-ordinated movement, plays an important role in the extent of reduction of perineal tension.     

Robot-assisted rectopexy and colpopexy for rectal prolapse

Aim

This video demonstrates a technique for robot-assisted combined rectopexy with colpopexy, but without the use of mesh for rectal prolapse.

Methods

This case features a 61-year-old woman who presents with complaints of tissue protruding through her rectum and fecal incontinence. On examination, she was found to have circumferential, full-thickness rectal prolapse and perineal descent. We present a technique that combines rectopexy with colpopexy without the use of mesh for repair of rectal prolapse. Postoperative examination revealed resolution of rectal prolapse and good perineal support. This video illustrates a technique that may serve as a useful adjunct to have in one’s surgical armamentarium in circumstances when mesh should not or cannot be used, such as in cases that require resection of the sigmoid colon or for patients who simply prefer to avoid the use of mesh.

Conclusion

Given that rectal prolapse and posthysterecomy vaginal vault prolapse often occur together, our institution routinely performs colpopexy with rectopexy for rectal prolapse to provide additional support to the pelvic floor as demonstrated in this video.     

Interposition grafts for rectovaginal fistula repair in the New Zealand white rabbit

Introduction and hypothesis

The objective was to use an animal model to study different types of interposition grafts for rectovaginal fistula repair.

Methods

Twelve New Zealand white rabbits underwent surgical creation of a rectovaginal fistula, followed by repair. Four repair techniques were studied; three with interposition grafts and one control group without a graft. Animals were euthanized at 4-week intervals and underwent gross and histologic analysis.

Results

The mean rectovaginal wall thickness was greatest in the control group (5.6 mm) and thinnest in the autologous rectus fascia (4.2 mm) and porcine small intestine submucosa (5.1 mm) groups. The polypropylene graft had a mean thickness of 5.4 mm and elicited a strong, protracted inflammatory response. All fistulas were successfully closed except one porcine small intestine submucosa repair.

Conclusions

There is no benefit from interposition graft use for rectovaginal fistula repair in our New Zealand white rabbit model.     

The rectovaginal septum: visible on magnetic resonance images of women with Mayer-Rokitansky-Küster-Hauser syndrome (Müllerian agenesis)

Introduction and hypothesis

Ongoing debate exists about whether the rectovaginal septum (Denonvilliers’ fascia) is myth or reality. This study evaluates magnetic resonance images (MRI) of women with Müllerian agenesis for the presence of fascial layers between the rectum and the bladder to test the hypothesis that this layer exists in the absence of the vagina.

Methods

This is a secondary analysis of a study describing MRI aspects in women with vaginal agenesis before and after laparoscopic Vecchietti procedure. Study participants (n?=?16) had a multiplanar pelvic MR scan. Images were evaluated independently by two investigators (MH, JOLD) for the appearance of layers separate from the bladder and rectum in the area of interest, with characteristic anatomical features of the septum.

Results

Participants’ mean age was 19.4?±?2.6 years ± standard deviation (SD). In 12 of 16 patients (75 %) a distinct layer between rectum and bladder was identified in either the axial (4/16; 25 %) or sagittal (12/16; 75 %) scan or both. Characteristic anatomical features included lateral attachment to the levator ani muscle, cranial fusion to the cul-de-sac peritoneum, and caudal insertion into the perineal body.

Conclusions

Three quarters of women with Müllerian agenesis have a visible layer between bladder and rectum. As none of the participants had a vagina, these results support the existence of a rectovaginal septum, separate from a vaginal adventitia.     

Management of H-type rectovestibular and rectovaginal fistulas

Introduction

H-type rectovestibular or rectovaginal fistulas are rare entities in the spectrum of anorectal malformations seen in North America. Management options described in the literature have included perineal repair, anterior perineal anorectoplasty, vestibuloanal pull-through, and limited or formal posterior sagittal anorectoplasty, with a reported recurrence rate of 5% to 30%. We describe our approach and outcome in the management of these patients.

Methods

In a series of 1170 females with anorectal malformation, we cared for 8 patients who had an H-type rectovestibular or rectovaginal fistula and reviewed their clinical presentation, diagnosis, operative technique, and postoperative course.

Results

The patients' presenting symptoms included passage of stool per vagina (6), constipation (3), labial abscess (1), and recurrent urinary tract infection (1). There was associated anorectal stenosis in 3 patients. The remaining 5 patients had normal anal openings. Endoscopy was not helpful in locating the fistulas, but the fistulas were all demonstrated on direct inspection under anesthesia. The fistula was located in the vestibule (4), vagina (3), or labia (1). One patient had an associated presacral mass. Two patients had been operated on twice previously using a perineal repair and a protective colostomy and presented with third recurrences. In 5 cases, a posterior sagittal approach was used, placing sutures circumferentially around the fistulous opening on the rectal side, ligating the fistula, and pulling down a normal segment of rectum to be placed in front of the repaired vaginal wall. In our last 3 cases, we performed a transanal mobilization of the anterior rectal wall, leaving the perineal body intact. After our repairs, the patients have been followed up for 3 months to 15 years with a median of 15 months, and we have seen no recurrences.

Conclusions

In addition to vaginal passage of stool, an H-type fistula should be suspected when there is a labial abscess in an infant, and an associated anal stenosis or presacral mass must be checked for. Direct inspection is the key, with a careful look in the vestibule, because endoscopy may miss the fistula. The essential technical point for repair is to get healthy anterior rectal wall to cover the area of fistula on the posterior vagina. A transanal approach, leaving the perineal body intact, is an excellent option for this repair.     

Digitation associated with defecation: what does it mean in urogynaecological patients?

Introduction and hypothesis

Obstructed defecation is a common symptom complex in urogynaecological patients, and perineal, vaginal and/or anal digitation may required for defecation. Translabial ultrasound can be used to assess anorectal anatomy, similar to defecation proctography. The aim of the present study was to determine the association between different forms of digitation (vaginal, perineal and anal) and abnormal posterior compartment anatomy.

Methods

A total of 271 patients were analysed in a retrospective study utilising archived ultrasound volume datasets. Symptoms of obstructed defecation (straining at stool, incomplete bowel emptying, perineal, vaginal and anal digitation) were ascertained on interview. Postprocessing of stored 3D/4D translabial ultrasound datasets obtained on maximal Valsalva was used to diagnose descent of the rectal ampulla, rectocoele, enterocoele and rectal intussusception at a later date, blinded to all clinical data.

Results

Digitation was reported by 39 % of our population. The position of the rectal ampulla on Valsalva was associated with perineal (p?=?0.02) and vaginal (p?=?0.02) digitation. The presence of a true rectocoele was significantly associated with perineal (p?=?0.04) and anal (p?=?0.03) digitation. Rectocoele depth was associated with all three forms of digitation (P?=?0.005–0.02). The bother of symptoms of obstructed defecation was strongly associated with digitation (all P?<?= 0.001), with no appreciable difference in bother among the three forms.

Conclusion

Digitation is common, and all forms of digitation are associated with abnormal posterior compartment anatomy. It may not be necessary to distinguish between different forms of digitation in clinical practice.

     

Presentation and management of rectovaginal fistulas after delivery

Introduction

Obstetric trauma leading to rectovaginal fistula (RVF) formation results from perineal laceration and/or from prolonged ischemia and necrosis following obstructed labor. Due to modern obstetric care fistulas are rare in industrialized countries.

Methods

Patients undergoing surgery for a RVF between January 2005 and December 2014 at the Department of Obstetrics and Gynecology, Tuebingen, Germany, were identified and their records were reviewed retrospectively.

Results

Of 48 patients, 13 developed RVF of obstetric etiology. Parity ranged from 2 to 4. RVF repair was performed in all patients using a transvaginal approach: fistula excision and multilayer closure (7 of 13) with Martius flap interposition (1 of 7) and sphincteroplasty (5 of 13). One RVF closed spontaneously. Due to significant destruction of the anal canal, large RVF and RVF recurrence, 4 of the 13 patients needed a temporary protective ileostomy. Fistula closure was achieved in 12 of 13 patients.

Conclusion

The choice of RVF repair should be tailored to the underlying pathology and type of repair done previously and the patient’s wishes

     

Single-incision mesh repair versus traditional native tissue repair for pelvic organ prolapse: results of a cohort study

Introduction and hypothesis

To compare the efficacy and safety of the Elevate? anterior and posterior prolapse repair system and traditional vaginal native tissue repair in the treatment of stage 2 or higher pelvic organ prolapse.

Methods

A cohort study was conducted between January 2010 and July 2012. Patients who underwent transvaginal pelvic reconstruction surgery for prolapse were recruited. The primary outcome was anatomical success 1 year after surgery. The secondary outcome included changes in the quality of life and surgical complications. Recurrence of prolapse was defined as stage 2 or higher prolapse based upon the pelvic organ prolapse qQuantification system.

Results

Two hundred and one patients (100 in the Elevate? repair group and 101 in the traditional repair group) were recruited and analyzed. The anatomical success rate of the anterior compartment was significantly higher in the Elevate? repair group than in the traditional repair group (98 % vs 87 %, p?=?0.006), but not for the apical (99 % vs. 6 %, p?=?0.317) or posterior (100 % vs 97 %, p?=?0.367) compartments after a median 12 months of follow-up. Both groups showed significant improvements in the quality of life after surgery with no statistical difference. Mesh-related complications included extrusion (3 %) and the need for revision of the vaginal wound (1 %). Those in the mesh repair group had a longer hospital stay (p?=?0.04), operative time (p?<?0.001), and greater estimated blood loss (p?=?0.05). Other complications were comparable with no statistical difference.

Conclusions

The Elevate? prolapse repair system had a better 1-year anatomical cure rate of the anterior compartment than traditional repair, with slightly increased morbidity.     

Endoscopic lithotripsy and vaginal excision of a calcified bladder-mesh extrusion

Introduction and hypothesis

Synthetic meshes have proven to increase efficacy of pelvic organ prolapse (POP) repair, but associated complications are not rare. Bladder mesh extrusion is one of the most serious adverse events following POP surgery with mesh. The aim of this video was to describe endoscopic and vaginal approaches for treating a bladder-mesh extrusion.

Methods

A 52-year-old female patient with a history of vaginal POP surgery with mesh was referred for severe pelvic and perineal pain, dyspareunia, and dysuria. She was found to have a bladder calculus on a mesh extrusion. The calculus was removed by endoscopic lithotripsy before vaginal mesh excision was performed.

Conclusions

With the use of synthetic vaginal mesh, the incidence of bladder-mesh extrusion could increase. This didactic video will be helpful to surgeons required to manage such cases using a minimally invasive treatment.

     

Gynecologic anatomic abnormalities following anorectal malformations repair

Background/aim

Patients may present with gynecologic concerns after previous posterior sagittal anorectoplasty (PSARP) for repair of an anorectal malformation (ARM). Common findings include an inadequate or shortened perineal body, as well as introital stenosis, retained vaginal septum, and remnant rectovestibular fistula. An inadequate or shortened perineal body may impact fecal continence, sexual function and recommendations regarding obstetrical mode of delivery. We describe our experience with female patients referred to our center for evaluation of their previously repaired ARM, with a specific focus on perineal body anatomy and concomitant gynecologic abnormalities. We outline our collaborative evaluation process and findings as well as subsequent repair and outcomes.

Visualization of synthetic mesh utilizing optical coherence tomography

Introduction and hypothesis

Owing to the recent upsurge in adverse events reported after mesh-augmented pelvic organ prolapse (POP) repairs, our aim was to determine whether the location and depth of synthetic mesh can be measured postoperatively within the vaginal tissue microstructure using optical coherence tomography (OCT).

Methods

Seventeen patients with prior mesh-augmented repairs were recruited for participation. Patients were included if they had undergone an abdominal sacral colpopexy (ASC) or vaginal repair with mesh. Exclusion criteria were a postoperative period of <6 months, or the finding of mesh exposure on examination. OCT was used to image the vaginal wall at various POP-Q sites. If mesh was visualized, its location and depth was calculated and recorded.

Results

Ten patients underwent ASC and 7 patients had 8 transvaginal mesh repairs. Mesh was visualized in 16 of the 17 patients using OCT. In all ASC patients, mesh was imaged centrally at the posterior apex. In patients with transvaginal mesh in the anterior and/or posterior compartments, the mesh was visualized directly anterior and/or posterior to the apex respectively. Mean depth of the mesh in the ASC, anterior, and posterior groups was 60.9, 146.7, and 125.7 μm respectively. Mesh was visualized within the vaginal epithelial layer in all 16 patients despite the route of placement.

Conclusion

In this pilot study we found that OCT can be used to visualize polypropylene mesh within the vaginal wall following mesh-augmented prolapse repair. Regardless of abdominal versus vaginal placement, the mesh was identified within the vaginal epithelial layer.     

Transvaginal primary repair of a suprasphincteric rectovaginal fistula

Introduction and hypothesis

Rectovaginal fistula repair is one of the most challenging gynecological surgical procedures. This video is intended to serve as a tutorial for surgical repair.

Methods

An 80-year-old woman who developed a traumatic suprasphincteric rectovaginal fistula was managed through layered transvaginal repair without flaps.

Results

Anatomy restoration was completed without complications.

Conclusion

The procedure described in this video was effective and safe. Vaginal route should be considered as a valid surgical approach for rectovaginal fistula repair.

     

The UK National Prolapse Survey: 10 years on

Introduction and hypothesis

To assess trends in the surgical management of pelvic organ prolapse (POP) amongst UK practitioners and changes in practice since a previous similar survey.

Methods

An online questionnaire survey (Typeform Pro) was emailed to British Society of Urogynaecology (BSUG) members. They included urogynaecologists working in tertiary centres, gynaecologists with a designated special interest in urogynaecology and general gynaecologists. The questionnaire included case scenarios encompassing contentious issues in the surgical management of POP and was a revised version of the questionnaire used in the previous surveys. The revised questionnaire included additional questions relating to the use of vaginal mesh and laparoscopic urogynaecology procedures.

Results

Of 516 BSUG members emailed, 212 provided completed responses.. For anterior vaginal wall prolapse the procedure of choice was anterior colporrhaphy (92% of respondents). For uterovaginal prolapse the procedure of choice was still vaginal hysterectomy and repair (75%). For posterior vaginal wall prolapse the procedure of choice was posterior colporrhaphy with midline fascial plication (97%). For vault prolapse the procedure of choice was sacrocolpopexy (54%) followed by vaginal wall repair and sacrospinous fixation (41%). The laparoscopic route was preferred for sacrocolpopexy (62% versus 38% for the open procedure). For primary prolapse, vaginal mesh was used by only 1% of respondents in the anterior compartment and by 3% in the posterior compartment.

Conclusion

Basic trends in the use of native tissue prolapse surgery remain unchanged. There has been a significant decrease in the use of vaginal mesh for both primary and recurrent prolapse, with increasing use of laparoscopic procedures for prolapse.
