Abstract
Multiple system atrophy (MSA) is a sporadic, fatal, and rapidly progressive neurodegenerative disease of unknown etiology that is clinically characterized by autonomic failure, parkinsonism, cerebellar ataxia, and pyramidal signs in any combination. Early onset and extensive autonomic dysfunction, including cardiovascular dysfunction characterized by orthostatic hypotension (OH) and supine hypertension, urinary dysfunction characterized by overactive bladder and incomplete bladder emptying, sexual dysfunction characterized by sexual desire deficiency and erectile dysfunction, and gastrointestinal dysfunction characterized by delayed gastric emptying and constipation, are the main features of MSA. Autonomic dysfunction greatly reduces quality of life and increases mortality. Therefore, early diagnosis and intervention are urgently needed to benefit MSA patients. In this review, we aim to discuss the systematic treatment of autonomic dysfunction in MSA, and focus on the current methods, starting from non-pharmacological methods, such as patient education, psychotherapy, diet change, surgery, and neuromodulation, to various drug treatments targeting autonomic nerve and its projection fibers. In addition, we also draw attention to the interactions among various treatments, and introduce novel methods proposed in recent years, such as gene therapy, stem cell therapy, and neural prosthesis implantation. Furthermore, we elaborate on the specific targets and mechanisms of action of various drugs. We would like to call for large-scale research to determine the efficacy of these methods in the future. Finally, we point out that studies on the pathogenesis of MSA and pathophysiological mechanisms of various autonomic dysfunction would also contribute to the development of new promising treatments and concepts.

Dig Dis 2022; 40:728-733. [PMID: 35100590 DOI: 10.1159/000522180] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/11/2021] [Accepted: 01/24/2022] [Indexed: 02/02/2023]
Abstract
BACKGROUND The treatment of solitary rectal ulcer (SRU) is challenging and controversial; generally, no response to conventional treatments can be obtained, particularly in patients with dyssynergic defecation (DD). We assessed the efficiency of biofeedback therapy (BFT) in patients who did not respond to conservative treatments and had coexistence of SRU and DD. METHODS BFT responses, as well as anorectal manometry and rectoscopy results of 20 patients with the coexistence of SRU and DD, were assessed. RESULTS Mean age was 32.5 years. Of the patients, 12 were female, and 8 of them were male. An average of 12 sessions of BFT was performed on the patients. Ulcer disappeared in 11 patients (55%) after BFT, and the ulcer size decreased in 3 patients (15%). However, ulcers healed in 9 (90%) of 10 patients whose DD pattern disappeared following BFT, and ulcers healed in only 20% of patients whose DD pattern continued (p = 0.005). The change in anal resting pressure after BFT was significant (p = 0.016). Ulcers were healed in 87.5% (7/8) of the patients whose anal resting pressure decreased after BFT and whose DD disappeared, while ulcers remained untreated in 85.7% of the patients whose anal resting pressure decreased, but the DD pattern continued (p = 0.005). CONCLUSIONS SRU patients with DD are typically unresponsive to medical treatments. Ameliorating anorectal dyssynergia should be the priority of treatment in these patients. BFT is an effective treatment for DD. BFT enhances the healing of ulcers in patients with SRU by restoring coordination of the pelvic floor.

Effect of biofeedback therapy on anorectal physiological parameters among patients with fecal evacuation disorder. Indian J Gastroenterol 2017; 36:99-104. [PMID: 28213843 DOI: 10.1007/s12664-017-0731-y] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/25/2016] [Accepted: 01/20/2017] [Indexed: 02/04/2023]
Abstract
BACKGROUND Though biofeedback therapy is often effective in patients with fecal evacuation disorder (FED), a common cause of chronic constipation (CC) in tertiary practice, data on anorectal physiological parameters following it are scanty. METHODS Consecutive patients with FED with CC diagnosed by abnormalities in at least two of the three tests (anorectal manometry, defecography, and balloon expulsion test [BET]) undergoing biofeedback (two sessions per day, 30 min each, for 2 weeks) during a 3-year period were analyzed. Clinical evaluation, anorectal manometry (ARM), and BET were performed at the beginning and after biofeedback. RESULTS Incomplete evacuation 42/43 (98%), straining 40/43 (93%), and feeling of outlet obstruction 35/43 (81%) were the most common symptoms among these 43 patients (median age 44 years, range 18-76, 30 [71%] male). All the three tests (defecography, BET, and ARM) were abnormal in 17 (40%) patients and the others had two abnormal tests. Improvement in physiological parameters was noted following biofeedback (median residual anal pressure during defecation 99 mmHg (range 52-148) vs. 78 mmHg (37-182), p = 0.03; maximum intra-rectal pressure 60 mmHg (90-110) vs. 76 mmHg (31-178); p = 0.01; defecation index 1.1 (0.1-23.0) vs. 3.2 (0.5-29.0); p = 0.001). Dyssynergia on ARM and BET got corrected in 22/34 (65%) and 18/30 (60%) patients. At a 1-month follow up, 23/37 (62%) patients reported satisfactory symptomatic improvement. CONCLUSIONS Biofeedback not only improves symptoms but also anorectal physiological parameters in patients with FED.

Abstract
Invasion and subsequent metastasis is the major cause of death from most cancers including prostate cancer. Herein we report on the potential tumor suppressive properties of Rab7, a GTPase that regulates trafficking of lysosomes. The movement of lysosomes to the cell surface in response to environmental cues increases the secretion of proteinases and cell invasion. We determined that Troglitazone and other members of the Thiazolidinedione family inhibit cell-surface directed lysosome trafficking and cathepsin B secretion through a Rab7-dependent mechanism. Moreover, Rab7 shRNA expressing cells were found to be more invasive in vitro and in vivo. Increased invasiveness was accompanied by elevated expression of the c-Met receptor and prolonged downstream signaling, thereby supporting a role for Rab7 as a mediator of signaling down-regulation. Taken together, these results suggested that Rab7 acts as a negative regulator of prostate tumor growth and invasion, providing further evidence for its potential as a tumor suppressor.

Abstract
PURPOSE The purposes of this study were: (1) to examine the efficacy of anorectal biofeedback (AB) for constipation compared to a biofeedback control (BC) treatment and (2) to examine the extent to which self-reported childhood sexual/physical abuse predicted biofeedback outcome. METHODS Twenty-one patients with pelvic floor dyssynergia were randomized to either (1) an AB arm, where patients learned to isolate the anal sphincter using an electromyography probe, or (2) a BC arm that controlled for the nonspecific effects of biofeedback, where patients learned to relax trapezius or temporalis muscles with EMG feedback. Both treatments were delivered by registered nurses for six sessions. Prior to randomization and post-treatment, patients completed the validated Constipation Severity Instrument and two measures of quality of life (QOL), the Irritable Bowel Syndrome-QOL, and the SF-36. Generalized estimating equations examined the within-group and between-group differences over time. RESULTS Pre- and post-treatment data were obtained for six AB and nine BC patients. AB patients' overall constipation severity scores decreased by 35.5% (vs. 15.3%), and their obstructive defecation symptom scores decreased by 37.9% (vs. 19.7%) compared to BC. A similar pattern was shown on the IBS-QOL. On the SF-36 Mental Health Composite (MCS), AB scores improved 28.0% compared to BC scores, which worsened 12.7%. Those without (vs. with) a childhood sexual/physical abuse history showed improvement on the MCS post-biofeedback. CONCLUSIONS While our sample was statistically underpowered, AB produced clinical improvements in constipation severity and QOL.

Abstract
AIM Anismus causes obstructed defecation as a result of inappropriate contraction of the puborectalis/external sphincter. Proctographic failure to empty after 30 s is used as a simple surrogate for simultaneous electromyography/proctography. Botulinum toxin is theoretically attractive but efficacy is variable. We aimed to evaluate the efficacy of botulinum toxin to treat obstructed defecation caused by anismus. METHOD Botulinum toxin was administered, under local anaesthetic, into the puborectalis/external sphincter of patients with proctographic anismus. Responders (resolution followed by recurrence of obstructed defecation over a 1- to 2-month period) underwent repeat injection. Nonresponders underwent rectal examination under anaesthetic (EUA). EUA-diagnosed rectal prolapse was graded using the Oxford Prolapse Grade 1-5. RESULTS Fifty-six patients were treated with botulinum toxin. Twenty-two (39%) responded initially and 21/22 (95%) underwent repeat treatment. At a median follow up of 19.2 (range, 7.0-30.4) months, 20/21 (95%) had a sustained response and required no further treatment. Isolated obstructed defecation symptoms (OR = 7.8, P = 0.008), but not proctographic or physiological factors, predicted response on logistic regression analysis. In 33 (97%) of 34 nonresponders, significant abnormalities were demonstrated at EUA: 31 (94%) had a grade 3-5 rectal prolapse, one had internal anal sphincter myopathy and one had a fissure. Exclusion of these alternative diagnoses revised the initial response rate to 96%. CONCLUSION Simple proctographic criteria overdiagnose anismus and underdiagnose rectal prolapse. This explains the published variable response to botulinum toxin. Failure to respond should prompt EUA seeking undiagnosed rectal prolapse. A response to an initial dose of botulinum toxin might be considered a more reliable diagnosis of anismus than proctography.

Abstract
PURPOSE This study came to compare the results of biofeedback retraining biofeedback (BFB), botulinum toxin botulinum type A (BTX-A) injection and partial division of puborectalis (PDPR) in the treatment of anismus patients. PATIENTS AND METHODS Consecutive patients treated for anismus fulfilled Rome II criteria for functional constipation at our institution were evaluated for inclusion. Participants were randomly allocated to receive BFB, BTX-A injection, and PDPR. All patients underwent anorectal manometry, balloon expulsion test, defecography, and electromyography activity of the anal sphincter. Follow up was conducted weekly in the first month then monthly for about 1 year. Study variables included clinical improvement, patient satisfaction, and objective improvement. RESULTS Sixty patients with anismus were randomized and completed the study. The groups differed significantly regarding clinical improvement at 1 month (50% for BFB, 75%BTX-A injection, and 95% for PDPR, P = 0.006) and differences persisted at 1 year (30% for BFB, 35%BTX-A injection, and 70% for PDPR, P = 0.02). Constipation score of the patients significantly improved postPDPR and BTX-A injection. Manometric relaxation was achieved significantly in the three groups. CONCLUSION Biofeedback retraining has a limited therapeutic effect, BTX-A injection seems to be successful for temporary treatment but PDPR is found to be an effective with lower morbidity in contrast to its higher success rate in treating anismus.

Abstract
The purpose of this study is to evaluate the predictive capability of anorectal physiologic tests for unfavorable outcomes prior to the initiation of biofeedback therapy in patients with dyssynergic defecation. We analyzed a total of 80 consecutive patients who received biofeedback therapy for chronic idiopathic functional constipation with dyssynergic defecation. After classifying the patients into two groups (responders and non-responders), univariate and multivariate analyses were performed to determine the predictors associated with the responsiveness to biofeedback therapy. Of the 80 patients, 63 (78.7%) responded to biofeedback therapy and 17 (21.3%) did not. On univariate analysis, the inability to evacuate an intrarectal balloon (P=0.028), higher rectal volume for first, urgent, and maximal sensation (P=0.023, P=0.008, P=0.007, respectively), and increased anorectal angle during squeeze (P=0.020) were associated with poor outcomes. On multivariate analysis, the inability to evacuate an intrarectal balloon (P=0.018) and increased anorectal angle during squeeze (P=0.029) were both found to be independently associated with a lack of response to biofeedback therapy. Our data show that the two anorectal physiologic test factors are associated with poor response to biofeedback therapy for patients with dyssynergic defecation. These findings may assist physicians in predicting the responsiveness to therapy for this patient population.

Abstract
Although extrapyramidal diseases are commonly thought to solely affect the extrapyramidal motor system, nonmotor symptoms such as behavioural abnormalities, dysautonomia, sleep disturbances and sensory dysfunctions are also frequently observed. Autonomic dysfunction as an important clinical component of extrapyramidal disease (idiopathic Parkinson's disease, multiple system atrophy, progressive supranuclear palsy, dementia with Lewy bodies) is often not formally assessed and thus frequently misdiagnosed. Symptoms of autonomic dysfunction in general impact more on quality of life than motor symptoms. Appropriate symptom-oriented diagnosis and symptomatic treatment as part of an interdisciplinary approach can greatly benefit the patient. Unfortunately, double-blind, randomized, controlled studies are scarce with the consequence that most recommendations are not based on the highest level of evidence. This review elaborates a limited overview on the treatment of cardiovascular, gastrointestinal, urogenital and sudomotor autonomic dysfunction in various extrapyramidal syndromes.

Abstract
PURPOSE This prospective study was designed to assess the efficacy and safety of a novel technique in treating outlet obstruction syndrome using a transanal double-stapling procedure. METHODS Two hundred thirty patients (187 female) with obstructed defecation underwent stapled transanal rectal resection over a six-year period with follow-up at 2, 6, and 12 months, then yearly; median follow-up was 24 (range, 12-68) months. All failed conservative measures. Patients with slow transit constipation and puborectalis dyssynergia were excluded. RESULTS Operating time was short (median, 35 (range, 20-95) minutes), with 159 (69%) performed as day cases (outpatient). Major complications were seen in 16 (7%); there were no deaths. Twelve (5%) patients reported severe postoperative pain. Immediate postoperative fecal urgency was reported by 107 (46%) patients, but persisted at six months in only 26 (11%). Three (1%) developed recurrent rectal prolapse. Nearly all incontinent patients (98%) reported an improvement, with a median Wexner score reduction of 5 points (P < 0.0001). Constipation improved in 77% of patients. Seventy-seven percent of patients were "very glad" they had the operation, and 86% "recommended" stapled transanal rectal resection to a friend. CONCLUSION Stapled transanal rectal resection can be performed on a day-case basis with high levels of patient satisfaction. Incontinence and constipation are improved. However, significant morbidity occurs in 7% of patients, and urgency of defecation persists beyond six months in 11%.

Abstract
PURPOSE Anismus is a significant cause of chronic constipation. This study came to revive the results of BFB training and BTX-A injection in the treatment of anismus patients. MATERIALS AND METHODS Forty-eight patients with anismus (33 women; mean age 39.6 +/- 15.9) were included in this study. All patients fulfilled Rome II criteria for functional constipation. All patients underwent anorectal manometry, balloon expulsion test, defecography, and electromyography (EMG) activity of the EAS. All patients had non-relaxing puborectalis muscle. The patients were randomized into two groups. Group I patients received biofeedback therapy, two times per week for about 1 month. Group II patients were injected with BTX-A. Follow-up was conducted weekly in the first month then monthly for about 1 year. RESULTS In the BFB training group, three patients quit before the end of sessions with no improvement; initial improvement was recorded in 12 patients (50%) while long-term success was recorded in six patients (25%). In the BTX-A group, clinical improvement was recorded in 17 patients (70.83%), but the improvement persisted only in eight patients (33.3%). There is a significant difference between BTX-A group and BFB group regarding the initial success, but this significant difference disappeared at the end of follow-up. Manometric relaxation was achieved significantly post-BFB and post-BTX-A injection with no significant difference between the two groups. CONCLUSIONS Biofeedback training has a limited therapeutic effect on patients suffering from anismus. BTX-A injection seems to be successful for temporary treatment of anismus.

Abstract
Obstructed defecation (OD) and fecal incontinence (FI) are challenging clinical problems, which are commonly encountered in the practice of colorectal surgeons and gastroenterologists. These disorders socially and psychologically distress patients and greatly impair their quality of life. The underlying anatomical and pathophysiological changes are complex, often incompletely understood and cannot always be determined. As a consequence, many medical, surgical, and behavioral approaches have been described, with no panacea. Over the past decade, advances in an understanding of these disorders together with rational and similar methods of evaluation in anorectal physiology laboratories (ARP), radiology studies, and new surgical techniques have led to promising results. In this brief review, we discuss treatment strategies and recent updates on clinical and therapeutic aspects of obstructed defecation and fecal incontinence.

Abstract
Rectal hyposensitivity (RH) relates to a diminished perception of rectal distension that is diagnosed during anorectal physiologic investigation. There have been few direct studies of this physiologic abnormality, and its contribution to the development of functional bowel disorders has been relatively neglected. However, it appears to be common in patients with such disorders, being most prevalent in patients with functional constipation with or without fecal incontinence. Indeed, it may be important in the etiology of symptoms in certain patients, given that it is the only "apparent" identifiable abnormality on physiologic testing. Currently, it is usually diagnosed on the basis of elevated sensory threshold volumes during balloon distension in clinical practice, although such a diagnosis may be susceptible to misinterpretation in the presence of altered rectal wall properties, and thus it is uncertain whether a diagnosis of RH reflects true impairment of afferent nerve function. Furthermore, the etiology of RH is unclear, although there is limited evidence to support the role of pelvic nerve injury and abnormal toilet behavior. The optimum treatment of patients with RH is yet to be established. The majority are managed symptomatically, although "sensory-retraining biofeedback" appears to be the most effective treatment, at least in the short term, and is associated with objective improvement in the rectal sensory function. Currently, fundamental questions relating to the contribution of this physiologic abnormality to the development of functional bowel disorders remain unanswered. Acknowledgment of the potential importance of RH is thus required by clinicians and researchers to determine its relevance.

Abstract
Obstructed defecation is a common problem that adversely affects the quality of life for many patients. Known causes of obstructed defecation include pelvic dyssynergy, rectocele, rectal intussusception, enterocele, pelvic organ prolapse, and overt rectal prolapse. Management of this condition requires an understanding of urinary, defecatory, and sexual function to achieve optimal outcomes. The goal of surgical treatment is to restore the various pelvic organs to their appropriate anatomic positions. However, there is a poor correlation between anatomic and functional results. It must be remembered that the pelvis contains many structures and that defects of pelvic support or function frequently affect other pelvic organs. Optimal outcomes can be achieved only by selecting appropriate treatment modalities that address all of the components of an individual patient's problem.

Abstract
OBJECTIVE Biofeedback is considered an effective treatment for anal constipation, but a substantial proportion of patients fail to improve. Our aim was to identify the key predictors of outcome using a comprehensive standardized evaluation of anorectal function. MATERIAL AND METHODS We retrospectively analysed the clinical and physiological data of 148 patients consecutively treated for constipation due to functional outlet obstruction by biofeedback. Clinical evaluation was performed by means of a structured questionnaire. Anorectal evaluation included anal pressure, neural reflexes, defecatory dynamics, rectal compliance, rectal sensitivity and balloon expulsion test. Biofeedback treatment was performed using a manometric technique. The clinical response to biofeedback treatment was evaluated as good (improvement of constipation) or poor (no improvement or worsening). RESULTS Of the 148 patients included, 112 (86 F, 26 M; age range 8-67 years) were followed-up for between 1 and 44 months, and 66% had a good response to treatment. The response depended on the severity of the defecatory dysfunction. Thus, lack of anal relaxation during straining and inability to evacuate a 1 ml intrarectal balloon were inversely related to physiological variables related to therapeutic success. Among the 49 patients with absent anal relaxation, 51% had a good response to treatment (versus 78% in patients with partial relaxation; p < 0.01), and among the 29 patients with failed balloon expulsion, 48% responded to treatment (versus 74% in patients able to evacuate > or = 1 ml intrarectal balloon; p < 0.05). CONCLUSIONS Even in the presence of negative predictors, biofeedback is a valuable treatment option in a substantial proportion of constipated patients.

Abstract
AIM: To study characteristics of anorectal pressure, EMG activity and effect of biofeedback training system on patient with chronic functional constipation (CFC).
METHODS: Anorectal manometry was carried out in 144 cases of CFC by a monitor system (liquid-phase type) and Biolab dynamics parameter before and after the biofeedback training. 20 healthy individuals were taken as control.
RESULTS: Compared with controls, CFC patients showed slightly lower anal quiesent pressure (P>0.05), lower anorectal sphincteric squeezing pressure (15.7±1.4 vs 12.7± 1.4) (P < 0.01), higher rectal defection volume thresholds and higher rectal maximum talerable volume thresholds (12±6.2 vs 14.9±6.6; 29.3±6.8 vs 36.0±7.3) (P < 0.01; P < 0.01); EMG assessments showed that 100% patients with CFC had the contradictory movement between the pelvic floor muscle (PFM) and abdominal anterior oblique muscle (AAOM). The movement extent of the PFM rose from 5.3±2.8 to 10.2±2.8 under quiet state (P < 0.01), and AAOM reduced from 34.4±5.2 to 30.8±4.9 (P < 0.01); All the abnormalities significantly improved with Orion PC/ 12 m EMG biofeedback training therapy. After biofeedback training therapy, symptoms of CFC patients were improved with efficient rate of 84.03%; With increase of the treatment time and shortenning of the interval and assistant training, the curative efficacy rose and the recurrence rate reduced (78.8% vs 91.7%; 69.2% vs 92.8%) (P < 0.05; P < 0.05).
CONCLUSION: CFC patients have abnormal anorectal pressure, sensation threshold and unusual anus electric activities. Biofeedback training therapy can improve the above-mentioned indexes and is effective in 84.03% of the patients. The relatively intensive long-time training can improve the curative rate in a short period, and family assistant training can reduce the recurrance rate of the disease.

Abstract
Functional constipation is a very common problem in Western societies. Functional outlet obstruction, part of the spectrum of functional constipation, is suspected when patients present with select symptoms. Diagnosis is commonly made with anorectal manometry, electromyography, and rectal evacuation tests. Abnormal test patterns include poor relaxation and contraction of the anal sphincter in response to attempted defecation and difficult rectal evacuation. Several treatment approaches have been tested in these patients. Biofeedback training is considered the most specific therapeutic modality, and it is particularly attractive because of its safety. This review provides an assessment of the diagnostic tests for functional outlet obstruction and summarizes current options for therapy.

Abstract
AIM: To determine the efficacy and long-term outcome of biofeedback treatment for chronic idiopathic constipation and to compare the efficacy of two modes of biofeedback (EMG-based and manometry-based biofeedback).
METHODS: Fifty consecutive contactable patients included 8 cases of slow transit constipation, 36 cases of anorectic outlet obstruction and 6 cases of mixed constipation. Two modes of biofeedback were used for these 50 patients, 30 of whom had EMG-based biofeedback, and 20 had manometry-based biofeedback. Before treatment, a consultation and physical examination were done for all the patients, related information such as bowel function and gut transit time was documented, psychological test (symptom checklist 90, SCL90) and anorectic physiological test and defecography were applied. After biofeedback management, all the patients were followed up. The Student’s t-test, chi-squared test and Logistic regression were used for statistical analysis.
RESULTS: The period of following up ranged from 12 to 24 months (Median 18 months). 70% of patients felt that biofeedback was helpful, and 62.5% of patients with constipation were improved. Clinical manifestations including straining, abdominal pain, bloating, were relieved, and less oral laxative was used. Spontaneous bowel frequency and psychological state were improved significantly after treatment. Patients with slow and normal transit, and those with and without paradoxical contraction of the anal sphincter on straining, benefited equally from the treatment. The psychological status rather than anorectal test could predict outcome. The efficacy of the two modes of biofeedback was similar without side effects.
CONCLUSION: This study suggests that biofeedback has a long-term effect with no side effects, for the majority of patients with chronic idiopathic constipation unresponsive to traditional treatment. Pelvic floor abnormalities and transit time should not be the selection criteria for treatment.
