Pelvic floor dyssynergia and bimodal rehabilitation: results of combined pelviperineal kinesitherapy and biofeedback training

Clinical Characteristics of Adult Functional Constipation Patients with Rectoanal Areflexia and Their Response to Biofeedback Therapy

Background: The London Classification for anorectal physiological dysfunction specifically proposes rectoanal areflexia (RA), which means the absence of a rectoanal inhibitory reflex (RAIR) based on a manometric diagnosis. Although RA is not observed in healthy people, it can be found in adult patients with functional constipation (FC). This study describes the clinical manifestations of adult patients with FC and RA and their response to biofeedback therapy (BFT). Methods: This retrospective study reviewed the reports of high-resolution anorectal manometry (HR-ARM) and the efficacy of BFT in adult patients with FC. In addition, the Constipation Scoring System (CSS) scale, Patient Assessment of Constipation Symptoms (PAC-SYM) scale, Patient Assessment of Constipation Quality of Life (PAC-QOL) scale, Zung’s Self-Rating Anxiety Scale (SAS), Zung’s Self-Rating Depression Scale (SDS), balloon expulsion test (BET), and the use of laxatives were assessed. Results: A total of 257 adult patients diagnosed with FC were divided into the RA group (n = 89) and the RAIR group (n = 168). In the RA and RAIR groups, 60 (67.4%) and 117 (69.6%) patients, respectively, had dyssynergic defecation (DD) during simulated defecation. Type II pattern of dyssynergia was most frequently observed in both groups. Compared with the RA group, the RAIR group showed a higher CSS score, physical discomfort score, and prevalence of inadequate relaxation of the anal sphincter (p < 0.001, p = 0.036, and p = 0.017, respectively). The anxiety and depression scores were not different between the two groups. The proportion of patients using volumetric and stimulant laxatives and their combination was significantly higher in FC patients with RA, whereas the efficacy of BFT was significantly lower (p = 0.005, p < 0.001, p = 0.045, and p = 0.010, respectively). Conclusion: Adult FC patients with RA may suffer more severe constipation and have a lower efficacy of BFT compared with those with RAIR.

Sampling reflex: pathogenic role in functional defecation disorder

BACKGROUND

The sampling reflex is necessary to begin defecation or flatulence. It consists of a simultaneous rectoanal inhibitory reflex (RAIR) mediated by relaxation of the internal anal sphincter and rectoanal excitatory reflex (RAER) mediated by contraction of the external anal sphincter. The aim of this study was to evaluate the sampling reflex in patients with functional defecation disorder (FDD).

METHODS

A prospective cohort study was conducted on 58 obstructed defecation syndrome (ODS) patients with FDD. All 58 patients and 20 controls were evaluated with anorectal manometry to study the sampling reflex. Quantitative RAIR (total duration of reflex; maximal amplitude of relaxation; residual pressure at the lowest point of the RAIR) and RAER data (maximal amplitude of contraction; duration) were obtained. The straining test on manometry was considered positive for FDD if there was a muscle contraction/lack of relaxation or an insufficient pressure gradient for the passage of feces. Defecography was performed on all the patients with assessment of the anorectal angle and persistence or increase of puborectalis indentation.

RESULTS

Fifty (86.2%) FDD patients had an altered sampling reflex, showing incomplete/short duration of RAIR and excessive contraction/duration of RAER. More specifically, there was a correlation between a positive straining test and a short total duration of RAIR (ρ 0.92) as well as with excessive duration of RAER (ρ 0.89). There was also a correlation between lack of muscle relaxation on defecography and short total duration of RAIR ((ρ 0.79) and between lack of muscle relaxation on defecography and excessive duration of RAER (ρ 0.83). Altered maximal amplitude relaxation had the highest sensitivity in detecting impairment of RAIR (87.9) while maximal amplitude contraction had the highest sensitivity in detecting impairment of RAER (89.6). High residual pressure at the lowest point of RAIR had the highest specificity in detecting impairment of RAIR (80.0) while RAER duration had the highest specificity in detecting impairment of RAER (77.7).

CONCLUSION

The sampling reflex is impaired in patients with FDD. This finding provides an important insight into the pathogenesis of obstructed functional defecation.

OUTLET OBSTRUCTED CONSTIPATION AND FECAL INCONTINENCE: IS REHABILITATION TREATMENT THE WAY? MYTH OR REALITY

Pelvic floor rehabilitation aims to address perineal functional and anatomic alterations as well as thoraco-abdominal mechanic dysfunctions leading to procto-urologic diseases like constipation, fecal and urinary incontinence, and pelvic pain. They require a multidimensional approach, with a significant impact on patients quality of life. An exhaustive clinical and instrumental protocol to assess defecation disorders should include clinical and instrumental evaluation as well as several clinical/physiatric parameters. All these parameters must be considered in order to recognize and define any potential factor playing a role in the functional aspects of incontinence, constipation and pelvic pain. After such evaluation, having precisely identified any thoraco-abdomino-perineal anatomic and functional alterations, a pelvi-perineal rehabilitation program can be carried out to correct the abovementioned alterations and to obtain clinical improvement. The success of the rehabilitative process is linked to several factors such as a careful evaluation of the patient, aimed to select the most appropriate and specific targeted rehabilitative therapy, the therapist's scrupulous hard work, especially as regards the patient's emotional and psychic state, and finally the patient's compliance in undertaking the therapy itself, especially at home. These factors may deeply influence the overall outcomes of the rehabilitative therapies, ranging from "real" success to illusion "myth".

Pelvic floor rehabilitation for defecation disorders

Pelvic floor rehabilitation is frequently recommended for defecation disorders, in both constipation and fecal incontinence. However, the lack of patient selection, together with the variety of rehabilitation methods and protocols, often jeopardize the results of this approach, causing difficulty in evaluating outcomes and addressing proper management, and above all, in obtaining scientific evidence for the efficacy of these methods for specific indications. The authors represent different gastroenterological and surgical scientific societies in Italy, and their aim was to identify the indications and agree on treatment protocols for pelvic floor rehabilitation of patients with defecation disorders. This was achieved by means of a modified Delphi method, utilizing a working team (10 members) which developed the statements and a consensus group (15 members, different from the previous ones) which voted twice also suggesting modifications of the statements.

Anorectal Manometry in Defecatory Disorders: A Comparative Analysis of High-resolution Pressure Topography and Waveform Manometry

Background/Aims

Whether high-resolution anorectal pressure topography (HRPT), having better fidelity and spatio-temporal resolution is comparable to waveform manometry (WM) in the diagnosis and characterization of defecatory disorders (DD) is not known.

Methods

Patients with chronic constipation (Rome III) were evaluated for DD with HRPT and WM during bearing-down “on-bed” without inflated rectal balloon and “on-commode (toilet)” with 60-mL inflated rectal balloon. Eleven healthy volunteers were also evaluated.

Results

Ninety-three of 117 screened participants (F/M = 77/16) were included. Balloon expulsion time was abnormal (> 60 seconds) in 56% (mean 214.4 seconds). A modest correlation between HRPT and WM was observed for sphincter length (R = 0.4) and likewise agreement between dyssynergic subtypes (κ = 0.4). During bearing down, 2 or more anal pressure-segments (distal and proximal) could be appreciated and their expansion measured with HRPT but not WM. In constipated vs healthy participants, the proximal segment was more expanded (2.0 cm vs 1.0 cm, P = 0.003) and of greater pressure (94.8 mmHg vs 54.0 mmHg, P = 0.010) during bearing down on-commode but not on-bed.

Conclusions

Because of its better resolution, HRPT may identify more structural and functional abnormalities including puborectal dysfunction (proximal expansion) than WM. Bearing down on-commode with an inflated rectal balloon may provide additional dimension in characterizing DD.

Short-term outcomes after rehabilitation treatment in patients selected by a novel rehabilitation score system (Brusciano score) with or without previous stapled transanal rectal resection (STARR) for rectal outlet obstruction

PURPOSE

The purpose of this study was to examine short-term outcomes of rehabilitation treatment in patients with or without previous stapled transanal resection (STARR) for rectal outlet obstruction by using a novel rehabilitation score system (Brusciano score).

METHODS

This is a retrospective cohort study conducted at a single tertiary referral institution including all patients with chronic functional constipation admitted to the outpatient unit from 2004 to 2009.

RESULTS

Among 330 consecutive patients, 247 (74.8 %) (204 females and 43 males) showing a significantly higher rehabilitation score (mean of 15.7 ± 1.8; range, 7-25) than healthy controls (mean, 3.2 ± 1.2; range 2-6) (p < .0001) were selected for rehabilitation. Of the 247 patients evaluated, group A (no previous surgery) consisted of 170 patients (53 males; mean age, 44.8 ± 12.9 years; range, 19-80) of which 38 presented mixed constipation, whereas group B (previous surgery) consisted of 77 patients (18 males; mean age, 47.0 ± 11.2 years; range, 22-81). The Brusciano score, Agachan-Wexner score and quality of life improved in both groups of patients after treatment. Better improvements of Brusciano and Agachan-Wexner scores were observed in patients with previous STARR (group B).

CONCLUSIONS

The rehabilitation score system employed in this study seems to be a useful tool in selecting and assessing the outcome of patients who might benefit from rehabilitation treatment. Constipation and quality of life were significantly improved by the rehabilitation treatment. Further studies are needed to clarify either the impact of rehabilitation treatment on long-term outcome of patients treated for rectal outlet obstruction or its role in those who develop problems over time.

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.

MR-defecography in obstructed defecation syndrome (ODS): technique, diagnostic criteria and grading

BACKGROUND

The aim of this study was to evaluate the use of a magnetic resonance (MR)-based classification system of obstructive defecation syndrome (ODS) to guide physicians in patient management.

METHODS

The medical records and imaging series of 105 consecutive patients (90 female, 15 male, aged 21-78 years, mean age 46.1 ± 5.1 years) referred to our center between April 2011 and January 2012 for symptoms of ODS were retrospectively examined. After history taking and a complete clinical examination, patients underwent MR imaging according to a standard protocol using a 0.35 T permanent field, horizontally oriented open-configuration magnet. Static and dynamic MR-defecography was performed using recognized parameters and well-established diagnostic criteria.

RESULTS

Sixty-seven out of 105 (64 %) patients found the prone position more comfortable for the evacuation of rectal contrast while 10/105 (9.5 %) were unable to empty their rectum despite repeated attempts. Increased hiatus size, anterior rectocele and focal or extensive defects of the levator ani muscle were the most frequent abnormalities (67.6, 60.0 and 51.4 %, respectively). An MR-based classification was developed based on the combinations of abnormalities found: Grade 1 = functional abnormality, including paradoxical contraction of the puborectalis muscle, without anatomical defect affecting the musculo-fascial structures; Grade 2 = functional defect associated with a minor anatomical defect such as rectocele ≤ 2 cm in size and/or first-degree intussusception; Grade 3 = severe defects confined to the posterior anatomical compartment, including >2 cm rectocele, second- or higher-degree intussusception, full-thickness external rectal prolapse, poor mesorectal posterior fixation, rectal descent >5 cm, levator ani muscle rupture, ballooning of the levator hiatus and focal detachment of the endopelvic fascia; Grade 4 = combined defects of two or three pelvic floor compartments, including cystocele, hysterocele, enlarged urogenital hiatus, fascial tears enterocele or peritoneocele; Grade 5 = changes after failed surgical repair abscess/sinus tracts, rectal pockets, anastomotic strictures, small uncompliant rectum, kinking and/or lateral shift of supra-anastomotic portion and pudendal nerve entrapment.

CONCLUSIONS

According to our classification, Grades 1 and 2 may be amenable to conservative therapy; Grade 3 may require surgical intervention by a coloproctologist; Grade 4 would need a combined urogynecological and coloproctological approach; and Grade 5 may require an even more complex multidisciplinary approach. Validation studies are needed to assess whether this MR-based classification system leads to a better management of patients with ODS.

Diagnostic value of pelvic floor ultrasound in constipation due to female pelvic floor dysfunction

Constipation caused by female pelvic floor dysfunction (FPFD) is closely related to pathological changes in the front, middle and back basins. Constipation caused by pathological changes in the back basin manifests itself as rectocele, internal rectal intussusception, enterocele, descending perineum, and pelvic floor dyssynergia. Constipation due to the pathological changes in the front and middle basins not only manifests the above symptoms but also exhibits the symptoms of uterine and bladder prolapse. Pelvic floor ultrasound allows observing pathological changes in the front, middle and back basins in patients with constipation caused by FPFD, analyzing the changes in structure and function of static and dynamic pelvic floors, and making a more systematic assessment of female pelvic floor lesions, which is conducive to guiding constipation treatment. Therefore, pelvic floor ultrasound has great value in constipation caused by FPFD. In this paper, we review the diagnostic value of pelvic floor ultrasound in constipation due to female pelvic floor dysfunction.

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

Chronic constipation is a common and extremely trou-blesome disorder that significantly reduces the quality of life, and this fact is consistent with the high rate at which health care is sought for this condition. The aim of this project was to develop a consensus for the diagnosis and treatment of chronic constipation and obstructed defecation. The commission presents its results in a “Question-Answer” format, including a set of graded recommendations based on a systematic review of the literature and evidence-based medicine. This section represents the consensus for the diagnosis. The history includes information relating to the onset and duration of symptoms and may reveal secondary causes of constipation. The presence of alarm symptoms and risk factors requires investigation. The physical examination should assess the presence of lesions in the anal and perianal region. The evidence does not support the routine use of blood testing and colonoscopy or barium enema for constipation. Various scoring systems are available to quantify the severity of constipation; the Constipation Severity Instrument for constipation and the obstructed defecation syndrome score for obstructed defecation are the most reliable. The Constipation-Related Quality of Life is an excellent tool for evaluating the patient‘s quality of life. No single test provides a pathophysiological basis for constipation. Colonic transit and anorectal manometry define the pathophysiologic subtypes. Balloon expulsion is a simple screening test for defecatory disorders, but it does not define the mechanisms. Defecography detects structural abnormalities and assesses functional parameters. Magnetic resonance imaging and/or pelvic floor sonography can further complement defecography by providing information on the movement of the pelvic floor and the organs that it supports. All these investigations are indicated to differentiate between slow transit constipation and obstructed defecation because the treatments differ between these conditions.

Obstructed defaecation: what is the role of rehabilitation?

AIM

The study was designed to evaluate the results of rehabilitative treatment in patients suffering from obstructed defaecation.

METHOD

Between January 2008 and July 2010, 39 patients (37 women, age range 25-73 years; and two men, aged 57 and 67 years) affected by obstructed defaecation were included in the study. After a preliminary clinical evaluation, including the Obstructed Defaecation Syndrome (ODS) score, defaecography and anorectal manometry were performed. All 39 patients underwent rehabilitative treatment according to the 'multimodal rehabilitative programme' for obstructive defaecation. At the end of the programme, all 39 patients were reassessed by clinical evaluation and anorectal manometry. Postrehabilition ODS scores were used to categorize patients arbitrarily into three classes, as follows: class I, good (score ≤ 4); class II, fair (score > 4 to ≤ 8); and class III, poor (score > 8).

RESULTS

After rehabilitation, there was significant improvement in the overall mean ODS score (P < 0.001). Thirty (76.9%) patients were included as class I (good results), of whom eight (20.5%) were symptom free. Five (12.8%) patients were considered class III. A significant postrehabilitative direct correlation was found between ODS score and pelvic surgery (ρ(s) = 0.54; P < 0.05). Significant differences were found between pre- and postrehabilitative manometric data from the straining test (P < 0.001), duration of maximal voluntary contraction (P < 0.001) and conscious rectal sensitivity threshold (P < 0.02).

CONCLUSION

After rehabilitation, some patients become symptom free and many had an improved ODS score.

Obstructed defecation: the role of anorectal manometry

BACKGROUND

The aim of the study was to evaluate the clinical usefulness of anorectal manometry (AM) in patients affected by obstructed defecation (OD).

METHODS

Between January 2007 and December 2010, 379 patients (287 women and 92 men) affected by OD were evaluated. After a preliminary clinical evaluation, defecography and AM were performed. The results were compared with those from 20 healthy control subjects.

RESULTS

Overall anal resting pressure was not significantly different between patients and controls. Maximal voluntary contraction (MVC) data were significantly lower when compared with those of controls (P < 0.01). The straining test was considered positive in 143 patients. No significant difference was noted between patients and controls in maximal tolerated volume data. Patients had a significantly higher conscious rectal sensitivity threshold than controls (P < 0.02).

CONCLUSIONS

A positive straining test, low MVC and impaired rectal sensation are the main abnormalities detected by AM in patients with OD.

The evaluation of constipation

Constipation is a major medical problem in the United States, affecting 2% to 28% of the population. Individual patients may have different conceptions of what constipation is, and the findings overlap with those in other functional gastrointestinal disorders. In 1999, an international panel of experts laid out specific criteria for the diagnosis of constipation known as the Rome II criteria. When patients present with complaints of constipation, a complete history and physical examination can elicit the cause of constipation. It is imperative to rule out a malignancy or other organic causes of the patient's symptoms prior to making the diagnosis of functional constipation. Many patients' symptoms can be relieved with lifestyle and dietary modification, both of which should be implemented before other potentially unnecessary tests are performed. Functional constipation is divided into two subtypes: slow transit constipation and obstructive defecation. Because many different terms are used interchangeably to describe these subtypes of constipation, physicians need to be comfortable with the language. Slow transit constipation is due to abnormal colonic motility. The diagnosis is made with the use of a colonic transit study. We continue to use a single-capsule technique as first described in the literature, but modifications of the capsule technique as well as scintigraphic techniques are validated and can be substituted in place of the capsule. Obstructive defecation is a much more complex problem, with etiologies ranging from rare diseases such as Hirschsprung's to physiologic abnormalities such as paradoxical puborectalis contraction. To fully evaluate the patient with obstructive defecation, anorectal manometry, defecography, and electromyography should be utilized. The different techniques available for each test are fully covered in this article. When evaluating each patient with constipation, it is important to keep in mind that the disease may be specific to one subtype or a combination of both subtypes. Because it is difficult to differentiate the subtypes from the patient's history, we feel it is imperative to evaluate patients fully for both slow transit and obstructive defecation prior to any surgical intervention. Furthermore, we have described many tests that need to be applied to one's population of patients on the basis of the capabilities and expertise the institution offers.

Clinical and instrumental parameters in patients with constipation and incontinence: their potential implications in the functional aspects of these disorders

PURPOSE

The aims of this study were to evaluate several clinical and instrumental parameters in a large number of patients with constipation and incontinence as well as in healthy controls and discuss their potential implications in the functional aspects of these disorders.

METHODS

Eighty-four constipated and 38 incontinent patients and 45 healthy controls were submitted to a protocol based on proctologic examination, clinico-physiatric assessment, and instrumental evaluation.

RESULTS

Constipated and incontinent patients had significantly worse lumbar lordosis as well as lower rate in the presence of perineal defense reflex than controls. Constipated but not incontinent patients had a lower rate of puborectalis relaxation than controls. Furthermore, worse pubococcygeal tests and a higher rate of muscle synergies presence, either agonist or antagonist, were observed in both constipated and incontinent patients compared to controls.

CONCLUSIONS

This study has demonstrated strong correlations between physiatric disorders and the symptoms of constipation and incontinence. Further studies designed to demonstrate a causal relationship between these parameters and the success of a specific treatment of the physiatric disorders on the proctology symptoms are warranted.

Psychophysiological profile in dyssynergic defecation patients: an individual and situational response specificity analysis

The aim of this study was to evaluate the temporal stability and the situational specificity of the intra-anal EMG-activity, as well as the individual specificity of this response in dyssynergic defecation patients. With this purpose, 26 individuals (13 with dyssynergic defecation and 13 without anorectal pathology) participated in two sessions of psychophysiological assessment, with an inter-session period of 1 week. At each session, the EMG-activity of external anal sphincter was recorded under four different conditions (baseline, voluntary contraction, reflex contraction and simulated defecation). The findings provide empirical evidence about temporal stability of the intra-anal EMG-activity, situational specificity of this response and the existence of a specific profile of intra-anal EMG-activity characteristic of patients with dyssynergic defecation.

Successful physical therapy for constipation related to puborectalis dyssynergia improves symptom severity and quality of life

PURPOSE

This study evaluated symptom severity and quality of life in patients with puborectalis dyssynergia before and after physical therapy.

METHODS

Twenty-two patients with puborectalis dyssynergia were prospectively enrolled into a multidisciplinary program for the treatment of pelvic floor and bowel disorders in this case series. All patients had functional constipation and evidence of puborectalis dyssynergia. Physical therapy and behavioral counseling were offered to all. Patients completed the Patient Health Questionnaire, the Patient-Assessment of Constipation Symptom Questionnaire, and the Patient-Assessment of Constipation Quality of Life Questionnaire.

RESULTS

Sixteen patients successfully completed the program. Symptom severity decreased after physical therapy (2.1 +/- 0.7 vs. 1.3 +/- 0.9, P = 0.007). Quality of life also improved significantly (2.6 +/- 0.8 vs. 1.5 +/- 1.0, P = 0.007). Patients reported less physical discomfort, fewer worries/concerns, and indicated satisfaction with treatment. The difference in symptom severity was highly correlated with improvement in quality of life (r = 0.7, P = .005).

CONCLUSIONS

Successful physical therapy for patients with puborectalis dyssynergia is associated with improvements in constipation-related symptoms and in quality of life.
