Abstract
Rectocele is defined as a hernia of the rectum with protrusion of the anterior rectal wall through the posterior wall of the vagina. This condition occurs commonly, with an estimated prevalence of 30-50% of women over age 50. The symptomatology that leads to consultation is variable but consists predominantly of anorectal and/or gynecological complaints such as dyschezia, requiring digital disimpaction maneuvers, pelvic heaviness, anal incontinence, or dyspareunia. Rectocele may be isolated or associated with other disorders of pelvic stasis involving cystocele and uterine prolapse. Complementary exams (dynamic imaging and anorectal manometry) are essential before deciding on the surgical management of this condition. The indications for surgical management of rectocele are based on the intensity of symptoms and the resulting deterioration in quality of life, and surgery should be discussed after failure of medical treatment. Different approaches are possible, although there is currently no real consensus in the literature. The initial approach depends on the type of rectocele: if it involves the low or mid rectum or is isolated, an approach from below (transanal, transperineal, or transvaginal approach) can be proposed, while, in the presence of a high rectocele and/or associated with various disorders of pelvic stasis, transabdominal rectopexy is more suitable.

Abstract
Posterior compartment vaginal prolapse can be approached with multiple surgical techniques, including transvaginally, transperineally, and transanally, repaired with either native tissue or with the addition of an augment. Augment material for posterior compartment prolapse includes biologic graft (dermal, porcine submucosal), absorbable mesh (Vicryl polyglactin), or nonabsorbable synthetic mesh (polypropylene). Anatomic success rates for posterior compartment repair with augment has ranged from 54% to 92%. Augmented posterior compartment repair has not been shown to have superior outcome to native tissue repair. The focus of this article is on the transvaginal approach comparing native tissue repair with graft or mesh augmented repair.

Abstract
The prevalence of posterior-compartment prolapse (rectocele) is not known. The authors have found that operative repair symptomatically improved a majority of patients with impaired defecation associated with a large rectocele, but this improvement was likely related at least in part to factors other than the size of the rectocele. Multiple surgical techniques are available for rectocele repair, and the literature is not clear regarding indications for each type of surgical intervention. This article reviews the literature regarding various types of posterior-compartment repair, and draws conclusions regarding their absolute efficacy and relative efficacy in comparison with one another.

Transperineal rectocele repair with polyglycolic acid mesh: a case series. Dis Colon Rectum 2007; 50:2085-92; discussion 2092-5. [PMID: 18049839 DOI: 10.1007/s10350-007-9067-5] [Citation(s) in RCA: 21] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/30/2006] [Revised: 04/02/2007] [Accepted: 04/06/2007] [Indexed: 02/08/2023]
Abstract
PURPOSE This study was designed to evaluate the outcome of transperineal rectocele repair using polyglycolic acid mesh. METHODS Eighty-three consecutive females with predominant, symptomatic Stage II or Stage III rectocele underwent transperineal rectocele repair using polyglycolic acid (Soft PGA Felt(R)) mesh and finished their six-month follow-up. No additional interventions, including levatoroplasty or perineorraphy, were performed. The preoperative and postoperative symptom scores and stages of the posterior vaginal wall prolapse were recorded. The end points were reassessed at six months, postoperatively. RESULTS Preoperatively, 39 patients had Stage II and 44 patients had Stage III rectocele. The mean total symptom score was 9.87 +/- 1.93, which was reduced to 1.62 +/- 0.59 postoperatively (P < 0.0001). Objective evaluation of anatomic repair revealed that 74 patients (89.2 percent) had anatomic cure. Surgical complications were seen in a total of seven patients (8.4 percent), including hemorrhage (3.6 percent) and wound infection (4.8 percent). Mesh erosion, mesh infection, or worsening of sexual function was not noted. CONCLUSIONS Transperineal repair of rectocele with the polyglycolic acid mesh is an efficient therapy for patients with rectocele. It is highly successful in eliminating symptoms of obstructed defecation, and it is free of significant complications.

Abstract
PURPOSE OF REVIEW Implanted grafts are increasingly used by pelvic reconstructive surgeons and gynecologists. In addition, the marketing of a variety of grafts has been aggressively expanded without scientific evidence to support their use. This review aims to provide an update of the current status and role of grafts in reconstructive pelvic surgery and to review the current knowledge of the biology of currently marketed synthetic and biologic grafts. RECENT FINDINGS Xenografts are preferable to human tissue-banked grafts due to more predictable integrity. How these biomaterials compare to synthetics in terms of surgical outcomes has not been well studied, however. Absorbable materials that mimic some behaviors of synthetic and biological materials have been developed. Furthermore, several new techniques have been advocated with limited studies. SUMMARY While the reduction of surgical failure rates in vaginal surgery is desirable, the addition of graft materials must demonstrate improvement in anatomical, functional, and quality of life outcomes over time. Furthermore, future complications due to improper placement or movement of a graft and the possible shrinkage of the graft are of concern. Therefore, significant research is necessary for the preclinical testing of materials, and expertise needs to be developed for the management of complications.

Abstract
Despite the lack of evidence, augmenting pelvic organ prolapse surgery with biologic graft or synthetic mesh is increasing. The objective of this review is to examine the available grafts and meshes and discuss the current data addressing the use of these implants in correction of apical, anterior, and posterior prolapse. Most of the studies are retrospective with few randomized controlled trials. There is level I evidence suggesting that repair of apical prolapse with abdominal sacral colpopexy using synthetic mesh results in improved outcomes. However, most of the data concerning graft or mesh incorporation in anterior or posterior repairs do not support augmentation with prosthesis.

Abstract
There has been growing interest in the use of grafts in pelvic reconstructive surgery. This article will address available graft materials and assess their clinical efficacy and safety. We conducted a Pubmed MEDLINE literature search for full-length English text studies with follow-up periods of at least one year. There are many reports on synthetic and biological graft materials; the majority are not well-designed, have short-term follow-up, small sample sizes, and poor outcome assessment. The use of non-absorbable synthetic grafts may offer excellent anatomical cure rates. However, it is associated with a high incidence of graft-related complications, including healing abnormalities and adverse bladder, bowel, and sexual function effects. These complications can be decreased with absorbable synthetic meshes, but efficacy is lower compared to non-absorbable ones. There is insufficient evidence in favor of biological grafts. In conclusion, based on current knowledge, routine application of grafts in pelvic reconstruction is not recommended. It is preferred that graft utilization be individualized, with close monitoring for complications.

Abstract
The development of different mesh materials has led to an improvement of the individual surgical correction of genital prolapse. Macroporous monofilamentous synthetic meshes seem to be the optimal material in case of recurrent prolapse or of severe insufficiency of the pelvic floor. The use of biological meshes shows a markedly better tolerance with fewer infections or erosions despite the lack of evidence-based information on their long-term efficacy and safety. The surgical correction of genital prolapse has to carefully consider all risks and benefits in order to improve quality of life. In this respect, mesh materials can be particularly advantageous in the recurrent situation.

Abstract
PURPOSE OF REVIEW The use of graft material and mesh in the setting of pelvic organ prolapse surgery has gained increasing popularity and attention in spite of lack of scientific evidence to support their use. The objective of this review is to discuss available synthetic and biologic graft materials, review operative techniques, and evaluate the anatomic and functional results of published data on graft augmented prolapse repairs and antiincontinence procedures. RECENT FINDINGS Natural biologic graft materials (such as fascia lata) have been used to augment prolapse surgery and have a theoretical advantage of causing less erosions; however, a renewed interest in the employment of synthetic mesh in the anterior and posterior segments has increased, partly due to the need to find improved materials with less inconsistent material strength. The insertion of 'tension-free' meshes for anterior and posterior vaginal wall prolapse may be promising, but studies with longer follow-up are necessary to determine their true efficacy and safety profile. SUMMARY The recent introduction of newer graft materials and minimally invasive surgical techniques for pelvic organ prolapse repair and stress incontinence has rapidly grown, despite the relative lack of evidence-based information to document their long-term efficacy and safety. Their current use must take into account the risk-benefit profile and be individualized for each surgical candidate. The ultimate goal is to correct both the anatomic and functional derangements seen in this patient population, while improving quality of life.

Abstract
OBJECTIVE To review recent literature on graft materials used in vaginal pelvic floor surgery. METHODS A Pubmed-search ("anterior vaginal wall" or "cystocele"), ("posterior vaginal wall" or "rectocele") and ("vaginal vault" or "pelvic prolapse") and ("mesh" or "erosion" or "graft" or "synthetic") from 1995 to 2005 was performed; recent reviews [Birch C.

Rectocele repair using biomaterial augmentation: current documentation and clinical experience. Obstet Gynecol Surv 2005;60:753-60 [4] were added. RESULT There are few prospective randomized trials that prove the benefit of implanting grafts in vaginal pelvic floor surgery. Many articles are retrospective case series with small sample sizes or incomplete outcome variables. Serious complications such as erosions are often not mentioned. Inconsistent or unclear criteria for anatomic cure make it difficult to compare outcomes. Quality of life issues such as dyspareunia, urinary or bowel symptoms are often ignored. CONCLUSION Due to a lack of well-designed prospective randomized trials, recommendations for using graft materials in vaginal reconstructive surgery cannot be made. At this time, grafts should have limited use in a carefully selected patient population.

Abstract
UNLABELLED Although the etiology of rectocele remains debated, surgical innovations are currently promoted to improve anatomic outcome while avoiding dyspareunia and alleviating rectal emptying difficulties following rectocele surgery. Use of biomaterials in rectocele repair has become widespread in a short time, but the clinical documentation of their effectiveness and complications is limited. Medline and the Cochrane database were searched electronically from 1964 to May 2005 using the Pubmed and Ovid search engines. All English language publications including any of the search terms "rectocele," "implant," "mesh," "biomaterial," "prolapse," "synthetical," "pelvic floor," "biological," and "compatibility" were reviewed. This review outlines the basic principles for use of biomaterials in pelvic reconstructive surgery and provides a condensation of peer-reviewed articles describing clinical use of biomaterials in rectocele surgery. Historical and new concepts in rectocele surgery are discussed. Factors of importance for human in vivo biomaterial compatibility are presented together with current knowledge from clinical studies. Potential risks and problems associated with the use of biomaterials in rectocele and pelvic reconstructive surgery in general are described. Although use of biomaterials in rectocele and other pelvic organ prolapse surgery offers exciting possibilities, it raises treatment costs and may be associated with unknown and potentially severe complications at short and long term. Clinical benefits are currently unknown and need to be proven in clinical studies. TARGET AUDIENCE Obstetricians & Gynecologists, Family Physicians TARGET AUDIENCE After completion of this article, the reader should be able to explain that the objective of surgical treatment is to improve anatomic outcome and alleviate rectal emptying difficulties, describe the efficacy of biomaterials in rectocele repair, and summarize the potential risks and problems associated with use of biomaterials in rectocele and pelvic reconstructive surgery.

Abstract
Pelvic organ prolapse is a common and growing condition for which women seek help and frequently undergo surgical management. Prolapse of the posterior vaginal wall, alone or in combination with other compartment defects, can be a challenge for the pelvic surgeon. A clear understanding of the normal anatomy, interactions of the connective tissue and muscular supports of the pelvis, and the relationship or lack of relationship between anatomy and function is required. Vaginal support defects occur with and without symptoms, and many of the symptoms attributed to pelvic organ prolapse can result from other causes. Pelvic pressure, the need to splint the perineum to defecate, impaired sexual relations, difficult defecation, and fecal incontinence are some of the symptoms that have been correlated with rectoceles. Whether the prolapse is the cause of these symptoms or is a result of straining and stretching of support tissues in women with defecation disorders is still unknown. We will present the current literature on these relationships and what evaluations are useful when caring for a woman with a rectocele and defecation disorders. Either pessaries or surgery can be used for treating rectoceles. Several surgical techniques have been described, including transvaginal, transanal, abdominal, and the use of graft materials to treat both anatomical defects and functional symptoms. The success, rationale, and complications of each approach, including anatomic cure, impact on defecation, and sexual function, are presented.

Abstract
There is increasing evidence to show that the use of surgical meshes reduces recurrence rates of hernia repair and anterior vaginal wall prolapse. The aim of this study was to determine the safety and efficacy of posterior colporrhaphy with mesh in patients with posterior vaginal prolapse. An ambispective observational study involving 90 patients was conducted with retrospective chart review and prospective subjective and objective assessments at the end of a 1-year study period. Apart from 2 of 90 (2.2%) minor hematoma incidents, there was no other major perioperative morbidity. Prevalence of common prolapse complaints of vaginal lump sensation, constipation, defecation difficulty and dyspareunia all improved significantly postoperatively (p<0.001). Surgical correction was achieved in 27 of 31 (83.9%) at 6 months and beyond. There was no mesh infection but minor vaginal mesh protrusion was found in 7 of 90 (7.8%) patients at 6-12 weeks and 4 of 31 (12.9%) patients at 6 months and beyond. All these were treated easily with trimming without the need of mesh removal. We conclude that posterior colporrhaphy with mesh is effective in treating posterior vaginal prolapse in short term.

Abstract
Graft augmentation for repair of recurrent pelvic organ prolapse is commonly used in reconstructive pelvic surgery. The reported complications are mainly late onset. We report a case of early-onset inflammatory reaction following bovine pericardium graft augmentation for posterior vaginal wall defect repair. A 49-year-old presented with a recurrent and symptomatic posterior vaginal wall defect. She underwent an uneventful site-specific repair and bovine graft augmentation. Her early postoperative course was complicated by inflammatory response to the graft presenting as intense pelvic floor spasm and urinary retention. The condition was managed conservatively and resolved subsequently. One year later, the patient continues to be asymptomatic. Transient intense pelvic floor spasm and urinary retention can be the result of inflammatory reaction following graft augmentation with bovine pericardium for posterior vaginal wall defect repair.

Abstract
BACKGROUND Rectocele is a common finding in patients with intractable evacuatory disorders. Although much rectocele surgery is conducted by gynecologists en passant with other forms of vaginal surgery, many reports lack appreciation of the importance of coincident anorectal symptoms, and do not report functional and clinical outcome data. The pathogenesis of rectocele is still controversial, as is the embryological and anatomical importance of the rectovaginal septum as well as recognizable defects in its integrity and its relevance in formal repair when rectocele is operated upon as the principal condition in patients with intractable evacuatory difficulty. DISCUSSION The investigation and surgical management of rectocele is controversial given the relatively small numbers of operated patients in any single specialist unit and the relative lack of prospective data concerning functional outcome in operated cases. The imaging of rectocele patients is currently in a state of change, and the newer diagnostic modalities including dynamic magnetic resonance imaging frequently display a multiplicity of pelvic floor disorders. When surgery is indicated, coloproctologists most commonly utilize an endorectal defect-specific repair, but there are few controlled randomized data regarding outcome and response criteria of specific symptoms with particular surgical approaches. A Medline-based literature search was conducted for this review to assess the clinical results of defect-specific rectocele repairs using the endorectal, transvaginal, transperineal, or combined approaches. Only the studies are included that report both pre- and postoperative symptoms including constipation, evacuatory difficulty, pelvic pain, the impression of a pelvic mass, fecal incontinence, dyspareunia or the need for assisted digitation to aid defecation. CONCLUSION The history of rectocele repair, its clinical and diagnostic features and the advantages, disadvantages and indications for the different surgical techniques are presented in this review. Suggested diagnostic and surgical therapeutic algorithms for management have been included. It is recommended that a multicenter controlled randomized trial comparing surgical approaches for symptomatic evacuatory dysfunction where rectocele is the principal abnormality should be conducted.

Abstract
PURPOSE The aim of the present study was to analyze the prognostic value of clinical data and physiologic tests in patients undergoing rectocele repair for obstructed defecation. METHODS Between 1988 and 1996, 89 consecutive female patients with obstructed defecation caused by a rectocele were enrolled in the study. Median age at time of presentation was 55 (range, 35-81) years. All patients underwent a combined transvaginal and transanal rectocele repair. End evaluation to assess long-term results was performed by an independent observer after a median duration of follow up of 52 (range, 12-92) months. The presence of the following five symptoms was evaluated: prolonged and unsuccessful straining at stool, feelings of incomplete evacuation, manual assistance during defecation, false urge to defecate, and a stool frequency of less than three times per week. When none or just one of these symptoms was present, outcome of rectocele repair was considered successful. The outcome was considered as a failure when two or more of these symptoms were recorded. Furthermore, all patients were asked to score the outcome of their operations as excellent, good, moderate, or poor. Clinical data and the results of physiologic tests obtained in patients with a poor outcome of surgery were compared with those obtained in patients with a successful outcome. RESULTS Objective outcome of rectocele repair, based on the presence of symptoms, was found to be successful in 63 (71 percent) patients. Sixty-one patients considered outcome of surgery excellent or good (69 percent). Graded subjective outcomes between the two groups showed significantly better grades in cases of success. Duration of symptoms, number of symptoms, age, parity, and previous hysterectomy had no influence on the final outcome of surgery. Defecographic parameters, such as size of the rectocele, barium trapping in the rectocele, poor rectal evacuation, or intussusception, had no prognostic value. Signs of anismus based on defecography, electromyography, and balloon-expulsion studies did not influence outcome of surgery. The presence of symptoms such as defecation frequency, manual assistance, severe straining, false urge to defecate, or feelings of incomplete evacuation had no impact on the outcome. However, in patients without a daily urge to defecate or with a stool frequency of less than once per week, results of rectocele repair were significantly worse than in patients with a daily urge to defecate or a defecation frequency of more than once per week or both. In 14 of 26 patients with a poor outcome, colonic transit studies were performed. A delayed passage was observed throughout the entire colon in seven patients, in the left part of the colon and the rectosigmoid colon in four patients, and in the rectosigmoid colon in one patient. In two patients colonic transit was normal. CONCLUSIONS Combined transvaginal and transanal rectocele repair is beneficial for the majority of patients with obstructed defecation. In patients without a daily urge to defecate or a stool frequency of less than once per week, indicating colonic malfunctioning, the outcome of rectocele repair seems to be poor.

Abstract
Videodefaecography allows identification of three different types of rectoceles: type I or digitiform rectocele, type II or rectocele with a lax rectovaginal septum, an anterior mucosal prolapse and a deep pouch of Douglas, and a type III in which a rectocele is associated with intussusception or even rectal prolapse. Furthermore, videodefaecography gave information on functional mechanisms resulting in incontinence or constipation. Surgical treatment should be tailored to the radiological and clinical findings: endoanal approach in type I, posterior colpomyorhaphy in type II and double abdomino-vaginal approach in type III. One hundred and fifty cases were prospectively treated according to this policy. Recurrence occurred in one out of 150 cases (1.3%). Incontinence was cured in 93% and constipation in 88%.

Abstract
Gynecologists have traditionally evaluated rectocele repair by its effect on vaginal function; coloproctologists have traditionally evaluated its effect on bowel function. Hence different operative criteria and surgical techniques have arisen, but with very little prospective, objective evaluation. The purpose of this review is to describe the surgical techniques used to repair the rectocele and the most common investigations used during its evaluation. Anorectal investigations identify concomitant pathology, may explain pathophysiology, provide objective outcome criteria and attempt to predict the patients that will most benefit from surgery. However, because of the complex neuromuscular, physiological and mechanical interactions that contribute to impaired rectal emptying, their usefulness in improving functional outcome has been limited. Many patients experience improvement, but still are left with some symptoms of impaired defecation despite anatomic correction.

Abstract
We assessed the efficacy of laparoscopic treatment of rectocele defect using a polyglactin mesh graft. From May 1, 1995, through September 30, 1995, we prospectively evaluated 20 women (age 38-74 yrs) undergoing pelvic floor reconstruction for symptomatic pelvic floor prolapse, with or without hysterectomy. Morbidity of the procedure was extremely low compared with standard transvaginal and transrectal approaches. Patients were followed at 3-month intervals for 1 year. Sixteen had resolution of symptoms. Laparoscopic application of polyglactin mesh for the repair of the rectocele defect is a viable option, although long-term follow-up is necessary.

Abstract
PURPOSE This study was designed to evaluate the results of rectocele repair and parameters that might be useful in selecting patients for this operation. METHODS Twenty-five patients with symptom-giving rectoceles were prospectively evaluated with a standardized questionnaire, physical examination, defecography, colon transit studies, anorectal manometry, and electrophysiology. Patients underwent posterior colporrhaphy and perineorrhaphy. They were followed postoperatively (mean, 1.0 year) with the same questionnaire, physical examination, defecography, anorectal manometry, and electrophysiology. RESULTS Constipation had improved postoperatively in 21 of 24 constipated patients (88 percent). At postoperative follow-up 13 patients (52 percent) had no constipation symptoms, 8 (32 percent) had occasional symptoms, and 4 (16 percent) had symptoms more than once per week. Four patients with rectocele at preoperative defecography, but not at physical examination, had favorable outcomes following surgery. The majority of patients not using vaginal digitalization preoperatively had improved with respect to constipation. All patients with pathologic transit studies had various degrees of constipation postoperatively. Constipation was not improved in two of five patients with preoperative paradoxic sphincter reaction. CONCLUSIONS Rectocele is one cause of constipation that can be treated with good results. Preoperative use of vaginal digitalization is not mandatory for a good postoperative result. Defecography is an important complement to physical examination. Patients with pathologic transit study might have a less favorable outcome of rectocele repair with respect to constipation. More studies about the significance of paradoxic sphincter reaction in these patients are indicated.

Abstract
Clinical, physiologic, and anatomic assessments were carried out in 22 female patients with symptomatic rectocele (Group A), 15 patients with asymptomatic rectocele (Group B), and 14 subjects having no rectocele (Group C). Resting and pressure, rectal pressure, rectal compliance, anorectal inhibitory reflex, and rectal sensation did not differ among the groups. Proctography revealed that the lengths of the rectocele during attempted defecation in groups A (1.6 [1.0-3.5] cm) (median and range) and B (1.6 [1.0-3.0] cm) were significantly greater than that in Group C (0.4 [0.1-0.9] cm) (P less than 0.001 in both groups). Median pelvic floor descent at rest in Groups A (4.3 [1.6-7.5] cm) (median and range) and B (4.3 [1.3-6.9] cm) were significantly greater than that in Group C (2.5 [1.2-5.0] cm) (P less than 0.001 and P less than 0.02, respectively). These results indicate that rectocele is not associated with any physiologic change apart from a significant increase of pelvic floor descent.
