The anatomy of the pelvic plexus in female cadavers: implications for retroperitoneal nerve-sparing surgery

Background

The inferior hypogastric plexus (IHP) is a crucial structure for female continence and sexual function. A nerve-sparing approach should be pursued to reduce the risk of pelvic plexus damage during retroperitoneal pelvic surgery.

Objectives

To analyse the relationship between the female IHP and several pelvic anatomical landmarks.

Materials and Methods

Standardised cadaveric dissection was performed on 5 nulliparous female cadavers. The relationships of the IHP and the mid-cervical plane (MCP), the mid-sagittal plane (MSP), and the uterosacral ligament (USL) were investigated.

Main outcome measures

Distance between IHP and MCP, MSP, and USL.

Results

Distances between the right IHP and the right MSP (mean distance: 16.3 mm; range: 10.0-22.5 mm) and the right USL (mean distance: 4.8 mm; range: 0-15.0 mm) were shorter than those between the left IHP and ipsilateral landmarks (left MSP distance: 23.5 mm; range 18.0-30.0 mm; left USL distance: 5.0 mm; range: 0-20.0 mm). Although the MCP was 3.3 mm (range: 2.5-4.0 mm) left and lateral to the midsagittal line, the right IHP was closer to the MCP (mean distance: 19.6 mm; range: 13.0-25.0 mm) than the left one (mean distance: 20.2 mm; range: 15.0-26.0 mm).

Conclusions

Distances between the right IHP and the MSP, MCP, and ipsilateral USL, are shorter compared to these associated to the left IHP.

What is new?

Right autonomic pelvic plexus is closer to the midline planes and the ipsilateral USL. These anatomical relationships may be greatly helpful for pelvic surgeon while facing retroperitoneal pelvic surgery and looking for a nerve-sparing approach.

A Randomized Clinical Trial Comparing Dubuisson Laparoscopic Lateral Suspension with Laparoscopic Sacropexy for Pelvic Organ Prolapse: Short-Term Results

BACKGROUND

Laparoscopic sacrocolpopexy (LSC) is the gold standard for the treatment of apical prolapse, although dissection of the promontory may be challenging. Laparoscopic lateral suspension (LLS) with mesh is an alternative technique for apical repair with similar anatomical and functional outcomes, according to recent studies. The purpose of this study was to compare these operative techniques.

METHODS

Women with uterine Pelvic Organ Prolapse Quantification (POP-Q) stage 2 were enrolled in this prospective study and were randomly allocated to the LLS or LSC group. At the 12-month follow-up, primary measures included both anatomical and functional outcomes. Perioperative parameters and complications were recorded.

RESULTS

A total of 93 women were randomized, 48 in the LLS group and 45 in the LSC group, with 2 women lost to follow-up in both groups. LSC anatomic success rates were 81.82% for the apical compartment and 95.22% for the anterior compartment. LLS anatomic success rates for the apical and anterior compartments were 90% and 92.30%, respectively. The mean operative time for LLS was 160.3 min, while for LSC it was 168.3 min. The mean blood loss was 100 mL in both procedures. Conversion to laparotomy was necessary in three women. Mesh erosion was not observed in any of the cases. In terms of the complication, Clavien-Dindo grade 1 was observed in two patients in the LLS group and a complication rated grade 3b was observed in one patient in LSC group.

CONCLUSIONS

LLS is a good alternative to LSC, with promising anatomical and quality-of-life results.

Advice for acquiring better exposure and the right cleavage planes. Presentation of some difficult cases during dissection.

Results

Step-by-step overview of the different steps of dissection involved in laparoscopic surgery for pelvic organ prolapse, specifying the most important anatomical landmarks for reference and at risk of damage and presenting tips to correctly perform the dissection.

Conclusion

Besides the great surgical technical skills required, deep knowledge of pelvic anatomy is key for performing laparoscopic surgery for pelvic organ prolapse safely, minimising complications and recurrence and improving quality of life and the overall success of surgery.

Laparoscopic approach to pelvic organ prolapse - the way to go or a blind alley?

Pelvic organ prolapse represents a relatively frequent diagnosis that requires attention due to its detrimental effect on quality of life. Not surprisingly, it is one of the commonest indications for surgery in premenopausal and postmenopausal women, often requiring a complex multidisciplinary approach. Traditional vaginal procedures are being gradually replaced by laparoscopic techniques, offering anticipated benefits in reduced recurrence and complication rates, while respecting the trend towards uterus sparing if desirable. Recently, questions about the safety of alloplastic materials used in pelvic organ prolapse surgery were raised, leading to official restrictions in their use, particularly for transvaginal application. As a result, laparoscopic procedures might appear slightly favored but caution must be taken to assure proper technique of mesh placement while maintaining high awareness of possible long-term mesh-related complications that require close surveillance. Therefore, adequate education and training becomes even more important to achieve optimal results and to avoid possible serious medico-legal charges.

Laparoscopic Mesh-Less Cervicosacropexy for Uterovaginal Prolapse

OBJECTIVES

This study aimed to evaluate surgical and clinical outcomes of laparoscopic mesh-less cervicosacropexy for the treatment of uterovaginal prolapse.

METHODS

This single institutional review board-approved prospective cohort study enrolled 46 consecutive, sexually active symptomatic women requiring surgical correction of uterovaginal prolapse, from July 2013 to March 2016. After supracervical laparoscopic hysterectomy, the cervix was suspended to the anterior longitudinal ligament of the sacral promontory through a continuous suture with plication and shortening of the right uterosacral ligament. Pelvic organs' function was evaluated through validated questionnaires during preoperative and postoperative follow-up evaluations. The anatomical recurrences of genital prolapse with a Pelvic Organ Prolapse Quantitative stage 2 or higher, in particular of central compartment (Pelvic Organ Prolapse Quantitative score C ≥-1), were recorded.

RESULTS

Mean ± SD age was 55.5 ± 10.9 years. Mean ± SD operating time was 97.4 ± 25.6 (range, 60-180) minutes. Mean ± SD hospitalization length was 3.6 ± 0.9 (range, 2-6) days. No intraoperative complications were recorded. Median length of follow-up was 24 (range, 12-38) months. During the follow-up period, the objective success rates for central compartment prolapse and for all compartments were 93.5% and 89.1%, respectively. No woman presented dyspareunia at follow-up. Thirty-nine women (84.8%) reported very high satisfaction related to surgery and 6 (13%) a moderate satisfaction. Overall Female Sexual Function Index, Knowles-Eccersley-Scott Symptom, and Bristol Female Lower Urinary Tract scores improved significantly after surgery, except for incontinence score domain.

CONCLUSIONS

Laparoscopic mesh-less cervicosacropexy represents an effective and feasible option for the surgical treatment of uterovaginal prolapse in sexually active women, avoiding postoperative complications due to the mesh use.

STARR with Contour Transtar for Obstructed Defecation Syndrome: Long-Term Results

INTRODUCTION

Obstructed defecation syndrome (ODS) is a widespread and disabling syndrome. With this study, we want to evaluate the long-term results of stapled transanal rectal resection (STARR) performed with Contour Transtar device in the treatment for ODS. A re-evaluation of 113 patients subjected to STARR from June 2007 to January 2010 was conducted.

METHODS

All the patients treated for symptomatic ODS with STARR with Contour Transtar were included in the study. We re-evaluate all patients treated in the study period with clinical examination and specific questionnaire to verify the stability of the functional results and the satisfaction at 5 years from surgery. Constipation was graded using the Agachan-Wexner constipation score; eventual use of aids to defecate and patient satisfaction were assessed preoperatively, 6 months and 5 years after surgery. Long-term complications were also investigated.

RESULTS

Constipation intensity decreased from the preoperative value of 15.8 (±4.9) to 5.2 (±3.9) (p < 0.0001) at 6 months and remained stable after 5 years (7.4 ± 4.1; p < 0.01). Patients who use laxatives and enema decrease from 74 (77%) and 27 (28%) to only 16 (17%; p < 0.001) and 5 (5%; p < 0.001), respectively, at 5-year follow-up. None continue to help themselves with digitations after surgery. Also the satisfaction rate remained stable (3.64 vs 3.81) during the 5 years of the study.

CONCLUSION

The long-term results have demonstrated the efficacy of the STARR with Contour Transtar in treating ODS and the stability over time of the defecatory improvements.

Nerve preserving vs standard laparoscopic sacropexy: Postoperative bowel function

AIM

To compare our developed nerve preserving technique with the non-nerve preserving one in terms of de novo bowel symptoms.

METHODS

Patients affected by symptomatic apical prolapse, admitted to our department and treated by nerve preserving laparoscopic sacropexy (LSP) between October, 2010 and April, 2013 (Group A or “interventional group”) were compared to those treated with the standard LSP, between September, 2007 and December, 2009 (Group B or “control group”). Functional and anatomical data were recorded prospectively at the first clinical review, at 1, 6 mo, and every postsurgical year. Questionnaires were filled in by the patients at each follow-up clinical evaluation.

RESULTS

Forty-three women were enrolled, 25/43 were treated by our nerve preserving technique and 18/43 by the standard one. The data from the interventional group were collected at a similar follow-up (> 18 mo) as those collected for the control group. No cases of de novo bowel dysfunction were observed in group A against 4 cases in group B (P = 0.02). Obstructed defecation syndrome (ODS) was highlighted by an increase in specific questionnaires scores and documented by the anorectal manometry. There were no cases of de novo constipation in the two groups. No major intraoperative complications were reported for our technique and it took no longer than the standard procedure. Apical recurrence and late complications were comparable in the two groups.

CONCLUSION

Our nerve preserving technique seems superior in terms of prevention of de novo bowel dysfunction compared to the standard one and had no major intraoperative complications.

Laparoscopic Nerve-Preserving Sacropexy

STUDY OBJECTIVE

To demonstrate our developed nerve-preserving technique during laparoscopic sacropexy (LSP) for multicompartment pelvic organ prolapse.

DESIGN

A step-by-step demonstration of our surgical procedure on video (Canadian Task Force classification II-2). Informed consent was obtained from the subject, and the applicable Institutional Review Board provided approval.

SETTING

Although sacropexy does remain the 'gold standard' procedure for apical prolapse [1], the subjective outcome of the procedure has been reported to be not so satisfactory as its anatomic outcome [2]. New onset bowel symptoms have been observed with voiding and sexual dysfunctions [3]. Published data revealed a correlation between iatrogenic denervation during LSP and postoperative dysfunctions [4-6]. We adopted a nerve-preserving approach with the aim of reducing the iatrogenic morbidity.

INTERVENTIONS

Our surgical nerve-preserving LSP technique from the promontory down to the right uterosacral ligament and the rectovaginal space proceeds in 3 steps: Step 1: Opening the peritoneum. The peritoneum is opened just medial to the right common iliac artery, approximately 20 to 30 mm above the sacral promontory, allowing a safe approach in an area far from nerves and vascular structures. Peritoneal incision is extended toward the promontory. The underlying presacral fascia containing the right hypogastric nerve (rHN) is identified and incised longitudinally. The presacral fascia and the rHN are then pushed medially to expose the longitudinal anterior vertebral ligament; the finding of the middle sacral veins represents the limit of any further medial dissection. Opening and displacement of the prevertebral fascia are not mandatory. Step 2: Opening the peritoneum of the right pelvic sidewall, respecting the integrity of the presacral fascia and of the rHN contained within it. An inverted L-shaped peritoneal incision extending from the sacral promontory up to the left uterosacral ligament is completed, with care taken to preserve the rHN identified previously. In proximity to the uterus, the dissection line crosses the upper edge of the right uterosacral ligament at its proximal third and extends medially. The rectovaginal space is opened and joined to the peritoneal tunnel with a section of the superficial layer of the right uterosacral ligament, preserving its deep nervous portion. Step 3: Dissection of the rectovaginal space, respecting the integrity of the rectal fascia. The rectovaginal space is fully dissected, and at its caudal edge the dissection is carried out laterally to the rectum upward to identify the pelvic parietal fascia covering the levator ani muscle, in the middle to the cranial edge of the perineal body. Preservation of the rectal fascia prevents possible injury to the middle rectal vessels and the rectal branches of the inferior hypogastric plexus, which runs close to the pelvic floor. The complete dissection of the rectovaginal space appears in an inverted V-shaped space covering approximately two-thirds of the posterior vaginal wall, with the apex at the convergence of the uterosacral ligaments. The procedure is completed with dissection of the vesicovaginal space through the creation of an avascular triangular-shaped space with the apex at the dorsal end of the bladder trigone and laterally limited by the superficial vascular layer of the vesicouterine ligaments. The bladder branches of the inferior hypogastric plexus run far from the surgical field in the deep portion of the vesicouterine ligaments.

CONCLUSION

A nerve-sparing approach to pelvic spaces during LSP is feasible following well-defined surgical steps, which allow the surgeon to visualize all of the nerve pathways and potentially dangerous anatomic structures.

Safety and perioperative morbidity of laparoscopic sacropexy: a systematic analysis and a comparison with laparoscopic hysterectomy

PURPOSE

The high prevalence of Pelvic Organ Prolapse (POP) along with the demographic trend of the ageing population raises the value of sacropexy in the treatment of POP. Thus, efforts to decrease risks associated with this procedure have the potential for public health impact. We examined the perioperative morbidity of laparoscopic sacropexy regarding the surgical access and compared it with the morbidity of one of the most common gynecological procedure, the laparoscopic hysterectomy. Our aim was to prove the safety of laparoscopic sacropexy.

METHODS

A retrospective evaluation of 80 consecutive laparoscopic sacropexies performed from Sept. 2012 until Oct. 2014 and 126 laparoscopic hysterectomies for a benign indication were undertaken. We assessed the anatomical outcome and the intra- and postoperative complications using the classification system according to Clavien-Dindo (CD).

RESULTS

Apical success rate after sacropexy was 100% and global success rate was 95% (POP-Q stage ≤1). The decline in hemoglobin was low in both groups and showed no statistically significant differences. Both operative time (P < 0.001) and the duration of hospitalization (P < 0.001) were longer in case of a sacropexy. Although overall intraoperative complications seemed more frequent during a sacropexy, differences were not statistically significant. Both early and late postoperative complications showed a higher rate of mild complications (CD-I/II) and a lower rate of severe complications (CD-IIIa/IIIb) after a sacropexy. The differences were not statistically significant.

CONCLUSION

The laparoscopic sacropexy represents a safe procedure with good anatomical outcome. Despite higher technical severity, it doesn't seem to bare higher risks for perioperative morbidity than the laparoscopic hysterectomy does.

Laparoscopic sacrocolpopexy: demonstration of a nerve-sparing technique

Laparoscopic sacrocolpopexy is a well-established technique to treat apical vaginal prolapse. De novo micturition disorders, pelvic pain, and defecation disorders have been reported and may be due to intraoperative compromise of the superior hypogastric plexus. The video demonstrates our technique for nerve-sparing laparoscopic sacrocolpopexy. The patient is a 62-year-old woman with symptomatic stage III posthysterectomy vaginal vault prolapse. Key steps of the procedure are opening the peritoneum at the level of the promontory, identification of the fibers of the superior hypogastric plexus, deep anterior and posterior dissection with attachment of the mesh to the vagina, displacement of the nerve fibers to the left side during suturing of the mesh to the longitudinal ligament, and complete peritonealization. This technique of the identification and protection of relevant nerve structures appears to be reproducible and can be considered by surgeons who perform laparoscopic sacrocolpopexy.

A Novel Operative Procedure for Pelvic Organ Prolapse Utilizing a MRI-Visible Mesh Implant: Safety and Outcome of Modified Laparoscopic Bilateral Sacropexy

Introduction. Sacropexy is a generally applied treatment of prolapse, yet there are known possible complications of it. An essential need exists for better alloplastic materials. Methods. Between April 2013 and June 2014, we performed a modified laparoscopic bilateral sacropexy (MLBS) in 10 patients using a MRI-visible PVDF mesh implant. Selected patients had prolapse POP-Q stages II-III and concomitant OAB. We studied surgery-related morbidity, anatomical and functional outcome, and mesh-visibility in MRI. Mean follow-up was 7.4 months. Results. Concomitant colporrhaphy was conducted in 1/10 patients. Anatomical success was defined as POP-Q stage 0-I. Apical success rate was 100% and remained stable. A recurrent cystocele was seen in 1/10 patients during follow-up without need for intervention. Out of 6 (6/10) patients with preoperative SUI, 5/6 were healed and 1/6 persisted. De-novo SUI was seen in 1/10 patients. Complications requiring a relaparoscopy were seen in 2/10 patients. 8/10 patients with OAB were relieved postoperatively. The first in-human magnetic resonance visualization of a prolapse mesh implant was performed and showed good quality of visualization. Conclusion. MLBS is a feasible and safe procedure with favorable anatomical and functional outcome and good concomitant healing rates of SUI and OAB. Prospective data and larger samples are required.

Bowel and bladder dysfunction following surgery within the presacral space: an overview of neuroanatomy, function, and dysfunction

INTRODUCTION AND HYPOTHESIS

The presacral space contains a dense and complex network of nerves that have significant effects on the innervation of the pelvic viscera and support structures. The proximity of this space to the bony promontory of the sacrum has lead to its involvement in an array of corrective surgical procedures for pelvic floor disorders including sacrocolpopexy and rectopexy. Other procedures involving the same space include presacral neurectomy which involves intentional transection of the contained neural plexus to relieve refractory pelvic pain and resection of retrorectal or presacral tumors. Potential complications of these procedures are postoperative constipation and voiding dysfunction.

METHODS

Our aim was to review the current published literature on outcomes following a variety of procedures involving the presacral space and review postoperative bowel and urinary function. We also include an overview of the functional and structural anatomy of the presacral space and its corresponding neural plexi.

RESULTS/CONCLUSIONS

We conclude that quality data are lacking on the short-term and long-term rates for bowel and bladder dysfunction following surgical procedures involving the presacral space.
