Female Pelvic and Reconstructive Surgery (FPRS) is a multidisciplinary subspecialty that combines the efforts of different professionals to benefit women with pelvic floor disorders.[1] Gynecologists, urologists and colorectal surgeons are working simultaneously and trying to offer the best treatment to their patients. However, each medical specialty presents different backgrounds, and this leads to different points of view for approaching a disease whose treatment could (or should) be carried out in a collaborative fashion. This is particularly important when surgical treatment is indicated.
The posterior compartment of the female pelvic floor is an interesting and scarcely explored area, with divergent opinions about the best way to manage it. These differences are so present that the International Urogynecological Association (IUGA) and the International Continence Society (ICS) recently decided to make a joint report about Female Anorectal Dysfunction.[2]
Rectocele is a bulging of the rectum that protrudes to the posterior vaginal wall and corresponds to half of all prolapse surgeries performed in the US.[3] Annually, 160,000 Pelvic Organ Prolapse (POP) surgeries are made in the US, and due to the aging population, there is a trend in the increase of number of procedures.[4] Considering that rectocele is part of the posterior compartment, the reconstruction of this area is still one of the most difficult aspects of pelvic floor surgery,[5] and its repair involves from simple plication to site-specific repair, as well as the use of synthetic and biological meshes.
The contribution of different specialties to the treatment of rectocele may have its peculiarities. However, these differences never have been investigated in depth. In a quick search on PubMed we were able to retrieve almost 1,200 abstracts using rectocele as keyword. However, only a single study addressing these differences was found. Surgeons and gynecologists have not reached a consensus regarding the nomenclature, diagnosis and treatment of rectocele.[6]
Colorectal surgeons refer to rectocele as the most prevalent clinical finding of the obstructive defecation syndrome (ODS), and it presents constipation, straining for defecation, fecal urgency (sense of incomplete evacuation), tenesmus, pelvic heaviness and self-digitation.[7] [8] Although rectocele may be associated to ODS, most studies point out that it is rather a consequence than a cause of ODS.[9]
Moreover, most studies frequently investigate the association of rectocele with adjuvant anatomical abnormalities. One classic example is the link between rectocele and intussusception. About 67.5% of patients with clinical diagnosis of rectocele present an intussusception on magnetic resonance defecography.[10] A study with postoperative proctograms indicated that the anterior rectal wall intussusception would have the same etiology as a rectocele, that is, a deficient recto-vaginal ligamentous support.[11]
Regarding diagnosis, colorectal surgeons usually classify rectocele by defecography, magnetic resonance imaging defecography, and endoanal ultrasonography, and the intensity of the symptoms may be scored by constipation degree or other anorectal symptoms. On the other hand, these professionals seldom or never use the Pelvic Organ Prolapse Quantification (POP-Q) classification.
Differently, gynecologists recognize rectocele as a clinical finding of pelvic organ prolapse (POP). No special importance is given to rectal examination and to the necessity for differential diagnosis with other anorectal disorders.[5] It seems to us that gynecologists investigate these patients in a more superficial fashion. Women generally present to gynecologists with other symptoms that are more relevant to them, such as urinary incontinence, and gynecologists in general apparently underestimate the clinical manifestations of rectocele in comparison to colorectal surgeons. There are two important questions that rise from this issue: is the training in ob-gyn residency programs adequate enough for approaching FPRS? Is there an adequate academic formation in colorectal surgery in ob-gyn residency programs? Efforts must be done to improve these possible flaws in the ob-gyn resident training program.
However, there are points of convergence between specialists when the patient presents symptoms of the rectocele. Expectant management should be employed even though differences can be observed according to symptoms. Colorectal surgeons are more prone to prescribe treatment with fibers and biofeedback training for rectoceles with ODS.[12] On the other hand, gynecologists tend to add the use of pessaries for some severe associated prolapses.[13]
Divergences begin when surgical treatment is taken into consideration. Colorectal surgeons prefer the transanal approach, such as stapled transanal rectal resection (STARR) and laparoscopic ventral rectopexy. These are the most common choices for rectoceles that coexist with intussusception.[7] [14] A robotic approach has also been utilized with favorable short-term results when compared with the laparoscopic rectopexy.[15] Rectoceles associated with internal rectal mucosal prolapse can be corrected by rectal prolapsectomy.[16] A recent meta-analysis showed that STARR may reduce ODS symptoms; however, it seems that its effect is overestimated.[17] Moreover, proctalgia, fecal urgency, and rectal bleeding are complications that can occur in patients who undergo to this procedure.
Gynecologists are more focused on the transvaginal approaches for simple rectoceles. A Cochrane review found that the posterior vaginal repair presents fewer current prolapse symptoms when compared with the transanal repair.[18] The other advantages would be the broader exposure when compared with the transanal repair and the possibility of correcting other concomitant pelvic prolapses (such as cystocele or uterine prolapse), or other posterior defects (posterior colporrhaphy, perineorrhaphy and site-specific defect repair).[5]
Finally, the use of meshes lacks consensus. Most of the authors use it as a combined transanal-transperineal and abdominal approach. Synthetic meshes in the posterior compartment are not recommended by the specialized societies (International Urogynecological Association, Society of Gynecological Surgeons, American Urogynecological Association) and the US Food and Drug Administration (FDA) released a public health notification warning surgeons about possible complications.[19]
Despite FPRS being a multidisciplinary specialty, differences regarding the diagnosis and treatment of rectocele are seen between gynecologists and colorectal surgeons. Medical societies that diagnose and treat rectocele should come together in a joint effort to stablish guidelines to standardize the approach of these patients, aiming to improve the diagnosis and treatment of rectocele. Both gynecologists and colorectal surgeons should gain more knowledge about anorectal disorders and transvaginal approaches for the surgical procedures. Multidisciplinary groups will enhance this proximity and improve patient care.
