Abstract
PURPOSE To evaluate the impact of two different parameters (body position and distension medium) on the rectal sensory test in patients with functional constipation and provide data support for the development of standardized operating procedures in clinical practice. METHODS Based on a single-center process of the rectal sensory test, 39 patients with functional constipation were recruited for rectal sensory test under different body positions and distension mediums. RESULTS Among the items of the Constipation Scoring System, the score of frequency of bowel movements showed a negative correlation with the first constant sensation volume (r = -0.323, P = 0.045). Conversely, the score of painful evacuation effort showed a positive correlation with the desire to defecate volume (r = 0.343, P = 0.033). There was a statistically significant difference in the first constant sensation volume (when the distension medium was gas) measured in different body positions (left lateral position, sitting position, squatting position), and the data measured in the squatting position were significantly higher than those in left lateral position (P < 0.05). In terms of research on distension medium, it was found that the first constant sensation volume measured in the squatting position (when the distension medium was water) was significantly lower than that of gas (P < 0.05). CONCLUSION For patients with functional constipation, there are differences in the results of rectal sensory tests between body positions and distension mediums. When conducting multicenter studies, it is necessary to unify the standard operating procedure (SOP) for operational details to ensure consistency and reliability of the test results.

Vollebregt PF, Wiklendt L, Burgell RE, Chaichanavichkij P, Dinning PG, Knowles CH, Scott SM. Abnormal Perception of Urge to Defecate: An Important Pathophysiological Mechanism in Women With Chronic Constipation. Am J Gastroenterol 2022; 117:1125-1136. [PMID: 35435855 DOI: 10.14309/ajg.0000000000001794] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/09/2021] [Accepted: 04/13/2022] [Indexed: 12/11/2022]
Abstract
INTRODUCTION Although the association of absent or attenuated "call to stool" with constipation is well-recognized, no studies have systematically evaluated the perception of urge to defecate in a well-defined cohort of patients with chronic constipation (CC). METHODS A prospective study of 43 healthy adult women and 140 consecutive adult women attending a tertiary center for investigation of CC. All participants completed a 5-day viscerosensory questionnaire, and all women with CC also underwent anorectal physiologic investigations. Normal urge perception and abnormal urge perception were defined using a Naive Bayes model trained in healthy women (95% having normal urge). RESULTS In total, 181 toilet visits in healthy women and 595 in women with CC were analyzed. Abnormal urge perception occurred in 70 (50.0%) women with CC. In this group, the urge to defecate was more often experienced as abdominal sensation (69.3% vs 41.4%; P < 0.0001), and the viscerosensory referral area was 81% larger (median pixels anterior: 1,849 vs 1,022; P < 0.0001) compared to women with CC and normal urge perception. Abnormal (vs normal) urge in women with CC was associated with more severe constipation (Cleveland Clinic constipation score: 19 vs 15 P < 0.0001), irritable bowel syndrome (45.7% vs 22.9% P < 0.0001), and a functional evacuation disorder on defecography (31.3% vs 14.3% P = 0.023). A distinct pattern of abnormal urge was found in women with CC and rectal hyposensitivity. DISCUSSION Abnormal urge perception was observed in 50% of women with CC and was frequently described as abdominal sensation, supporting the concept that sensory dysfunction makes an important contribution to the pathophysiology of constipation.

Barostat or syringe-assisted sensory biofeedback training for constipation with rectal hyposensitivity: A randomized controlled trial. Neurogastroenterol Motil 2022; 34:e14226. [PMID: 34431186 DOI: 10.1111/nmo.14226] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/09/2021] [Revised: 07/06/2021] [Accepted: 07/07/2021] [Indexed: 12/20/2022]
Abstract
BACKGROUND Rectal hyposensitivity (RH) is a well-known pathophysiological dysfunction in chronic constipation. Whether biofeedback training improves RH and restores bowel function is unknown. AIM To investigate the efficacy of barostat-assisted sensory training (BAST) with syringe-assisted sensory training (SAST) in patients with RH in a randomized controlled trial. METHODS Patients with RH and chronic constipation (Rome III) were randomized to receive 6 biweekly sessions of BAST or SAST. Verbal/visual feedback was provided during repeated rectal distensions to improve defecation desire/urge and first sensations with either 10-cm balloon connected to barostat (BAST) or 4-cm balloon connected to syringe and manometry probe (SAST). Sensory thresholds, bowel symptoms, and therapist and patient's rating of treatments were compared. The primary outcome (responders) was the improvement in ≥2 sensory thresholds. RESULTS Sixty-six patients were enrolled: 32 received BAST, 34 received SAST, and 56 completed study. There were significantly more responders in BAST group than SAST (78% vs. 53%, p = 0.0320). Rectal sensation normalized in 81% with BAST compared to 56% with SAST (p = 0.0270). When compared to baseline, desire and urge to defecate thresholds and bowel satisfaction improved with BAST (p = 0.0013; p = 0.0002; p = 0.0001) and SAST (p = 0.0012; p = 0.0001; p < 0.0001) and number of complete spontaneous bowel movements with BAST (p = 0.0029) but without inter-group differences. Therapists rated BAST as superior to SAST (p < 0.0001), but patients rated both equally. CONCLUSIONS Sensory biofeedback training was effective and significantly improved rectal sensation and constipation symptoms. Although both techniques were useful, the novel BAST was more efficacious and easier to administer for treating RH.

Efficacy of combination of biofeedback therapy and pelvic floor muscle training in dyssynergic defecation. Acta Gastroenterol Belg 2021; 84:577-583. [PMID: 34965039 DOI: 10.51821/84.4.008] [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] [Indexed: 11/21/2022]
Abstract
BACKGROUND It is now known that with appropriate exercises, the functions of the muscles in the body ameliorate and increase in strength. We applied pelvic floor muscle relaxation training and exercises that strengthen the abdominal and pelvic muscles in combination with biofeedback therapy (BFT) to patients with dyssynergic defecation (DD). METHODS Patients who met the criteria for DD and had no underlying organic cause were included in this study. The electromyography (EMG) technique was used for BFT therapy. Patients had received at least six sessions of BFT. BFT was considered successful in patients when the DD pattern in anorectal manometry (ARM) disappeared and/or adequate anal relaxation was obtained following BFT and in patients who had full clinical recovery. RESULTS Data of 104 patients (58 females [55.8%] and 46 males [44.2%]) was evaluated. Abdominal and rectal symptoms disappeared in 71 (68.26%) patients. Of the patients who achieved symptomatic improvement, 58 (55.76%) saw a disappearance of the dyssynergic defecation pattern. When the differences between anal sphincter pressures before and after treatment were compared in patients who responded to BFT and those who did not, no significant differences were observed, but significant changes were found in anal squeezing pressures. It was found that those who had high squeezing pressures before BFT, those who increased their squeezing pressures after BFT, and those who decreased their resting pressure responded better to BFT. CONCLUSIONS In this study, BFT was found to be more effective in those with a high squeezing pressure and those that increased squeezing pressure after BFT. These findings will influence the treatment of patients with dyssynergic defecation who do not respond to treatment. A combination of abdominal and pelvic floor muscle exercises and BFT increases patient response.

Abstract
INTRODUCTION Normal bowel function requires intact sensory pathways. Diminished rectal sensation (rectal hyposensitivity [RH]) is associated with constipation, although its clinical importance remains unclear. METHODS Consecutive patients (aged 18-80) attending a tertiary center (2004-2016) for investigation of refractory functional constipation (Rome IV core criteria defined, applied post hoc) were included. Patients completed a clinical symptom questionnaire and underwent anorectal physiologic investigations, including rectal sensory testing (balloon distension) to determine 3 well-established sensory thresholds. Multivariate regression analyses were performed to evaluate associations between RH, symptomology, and allied physiologic investigations. RESULTS Of 2,876 patients meeting inclusion criteria, 722 (25%) had RH based on ≥1 elevated sensory thresholds (0: n = 2,154 [74.9%]; 1: n = 327 [11.4%]; 2: n = 209 [7.3%]; and 3: n = 186 [6.5%]). A linear relationship existed between increasing number of elevated sensory thresholds and constipation severity (Cleveland Clinic constipation score: mean difference per threshold [95% confidence interval] 0.69 [0.48-0.90]; P < 0.001). Several symptoms were significantly (P < 0.05) associated with RH including: infrequent defecation (odds ratio 1.29 [1.17-1.42]), painful evacuation (1.15 [1.05-1.27]), prolonged toileting (1.14 [1.05-1.24]), and digitation or enema use (1.18 [1.08-1.30]). On defecography, a "functional" evacuation disorder was also associated with RH (1.37 [1.25-1.50], P < 0.001), as was megarectum (2.52 [2.08-3.05], P < 0.001). DISCUSSION RH occurs in 25% of patients with refractory functional constipation. Increased number of elevated sensory thresholds is associated with more severe constipation phenotype. These data, in the largest study to date, provide for the first time evidence to show that RH is a major pathophysiologic mechanism in constipation, with recognized clinical impact (http://links.lww.com/AJG/B765).(Equation is included in full-text article.).

[PMID: 33027482 DOI: 10.1590/s0004-2803.202000000-56] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/04/2020] [Accepted: 06/22/2020] [Indexed: 11/22/2022]
Abstract
BACKGROUND Evacuation disorders are prevalent in the adult population, and a significant portion of cases may originate from pelvic floor muscle dysfunctions. Anorectal manometry (ARM) is an important diagnostic tool and can guide conservative treatment. OBJECTIVE To evaluate the prevalence of pelvic dysfunction in patients with evacuation disorders through clinical and manometric findings and to evaluate, using the same findings, whether there are published protocols that could be guided by anorectal manometry. METHODS A retrospective analysis of a prospective database of 278 anorectal manometries performed for the investigation of evacuation disorders in patients seen at the anorectal physiology outpatient clinic of Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto between January 2015 to June 2019 was conducted. The following parameters were calculated: resting pressure (RP), squeeze pressure (SP), high-pressure zone (HPZ), rectal sensitivity (RS) and rectal capacity (RC). The pressure measurements and manometric plots were reviewed to determine the diagnosis and to propose potential pelvic physical therapy procedures. Analysis of variance (ANOVA) and Fisher's exact test were used to compare the continuous variables and to evaluate the equality of variances between groups of patients with fecal incontinence (FI) and chronic constipation (CC). Results with a significance level lower than 0.05 (P-value <0.05) were considered statistically significant. Statistical analysis was performed using IBM® SPSS® Statistics version 20. RESULTS The mean age of the sample was 45±22 years, with a predominance of females (64.4%) and economically inactive (72.7%) patients. The indications for exam performance were FI (65.8%) and CC (34.2%). Patients with FI had lower RP (41.9 mmHg x 67.6 mmHg; P<0.001), SP (85.4 mmHg x 116.0 mmHg; P<0.001), HPZ (1.49 cm x 2.42 cm; P<0.001), RS (57.9 mL x 71.5 mL; P=0.044) and RC (146.2 mL x 195.5 mL; P<0.001) compared to those of patients with CC. For patients with FI, the main diagnosis was the absence of a functional anal canal (49.7%). For patients with CC, the main diagnosis was outflow tract obstruction (54.7%). For patients with FI, the main protocol involved a combination of anorectal biofeedback (aBF) with tibial nerve stimulation (TNS) (57.9%). For patients with CC, the most indicated protocol was aBF combined with TNS and rectal balloon training (RBT) (54.7%). CONCLUSION There was a high prevalence of pelvic floor changes in patients with evacuation disorders. There was a high potential for performing pelvic floor physical therapy based on the clinical and manometric findings.

Abstract
The symptoms of constipation and obstructed defecation are common in women with pelvic floor disorders. Female pelvic medicine and reconstructive surgery specialists evaluate and treat women with these symptoms, with the initial consultation often occurring when a woman has the symptom or sign of posterior compartment pelvic organ prolapse (including rectocele or enterocele) or if a rectocele or enterocele is identified in pelvic imaging. This best-practice statement will review techniques used to evaluate constipation and obstructed defecation, with a special focus on the relationship between obstructed defecation, constipation, and pelvic organ prolapse.

Abstract
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.

Abstract
The physiological mechanism of functional constipation (FC) includes defecatory disorders and delayed colon transit. About 18% to 68% constipated patients may have rectal hyposensitivity (RH). We performed this study to investigate the association between RH and functional defecatory disorder (FDD) as well as that between RH and delayed colon transit in FC patients.A total of 218 FC patients were enrolled. The constipation severity instrument (CSI) was used to assess constipation symptoms. High-resolution anorectal manometry (HR-ARM), defecography, balloon expulsion tests, and colon transit studies were performed for each patient. RH was defined as 1 or more sensory threshold pressures raised beyond the normal range based on HR-ARM. We investigated the association between RH and constipation symptoms, and the occurrence of FDD and delayed CTT. Ninety FDD patients completed the initial phase of biofeedback treatment (BFT). We investigated the association between RH and the effect of BFT.Totally 122 (56.0%) patients had RH. The total CSI (49.82 ± 1.09 vs 41.25 ± 1.55, P = 0.023) and obstructive defecation subscale scores (23.19 ± 0.69 vs 17.07 ± 0.90, P < 0.001) were significantly higher in RH than in non-RH patients. No significant difference was observed in slow transit symptoms (21.77 ± 0.72 vs 19.90 ± 0.85, P = 0.121) or abdominal pain (6.85 ± 2.61 vs 5.00 ± 1.04, P = 0.380). The frequency of prolonged CTT was not significantly different between RH and non-RH groups (54.1% vs 58.3%, P = 0.403). RH patients rated more occurrence of FDD (72.1% vs 53.1%, P = 0.014) and dysynergic defecation (79.8% vs 50.2%, P = 0.004) than non-RH patients, whereas no differences were seen for inadequate defecatory propulsion (59.2% vs 55.0%, P = 0.589). After BFT, the proportion of "no effect" was significantly higher in the RH group than in the non-RH group (22.4% vs 9.4%, P = 0.010).RH is associated with obstructive defecation symptoms and the occurrence of FDD. Further studies are needed to detect the mechanism of RH's effect on BFT and FC.

Abstract
Electroacupuncture (EA) has been shown to improve impaired gastric motility and slow waves in both humans and animals. However, its effects on colonic motility have rarely been investigated. The aim of this study was to investigate the effects and underlying mechanisms of EA on impaired colonic motility induced by rectal distension (RD)in dogs. Colon contractions and transit were measured in various sessions with and without EA in hound dogs chronically placed with a colonic cannula. Colonic contractile activity was assessed by motility index (MI). Autonomic functions were determined by the spectral analysis of the heart rate variability derived from the electrocardiogram. It was found 1) RD suppressed colonic motility by 40.5% (10.8 ± 0.9 with RD vs. 6.4 ± 0.8 at baseline, P < 0.002). EA at ST36 normalized colonic contractions suppressed by RD (12.9 ± 2.8, P < 0.002 vs. RD and P = 0.1 vs. control). 2) Administration of atropine blocked the ameliorating effect of EA on colon motility. 3) RD also delayed colonic transit (65.0 ± 2.0% with RD vs. 86.0 ± 1.9% without RD, P < 0.001) that was restored with EA (84.0 ± 1.9%, P = 0.178 vs. control). 4) EA increased vagal activity suppressed by RD (0.37 ± 0.07 with RD + EA vs. 0.09 ± 0.03 with RD without EA, P < 0.001). In conclusion, RD inhibits colonic contractions and delays colonic transit in dogs; EA at ST36 restores the RD-induced impairment in both colonic contraction and transit by enhancing vagal activity and mediated via the cholinergic pathway.

Long-term efficacy of biofeedback therapy in patients with dyssynergic defecation: results of a median 44 months follow-up. Neurogastroenterol Motil 2015; 27:787-95. [PMID: 25807997 DOI: 10.1111/nmo.12552] [Citation(s) in RCA: 44] [Impact Index Per Article: 4.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/26/2014] [Accepted: 02/22/2015] [Indexed: 12/24/2022]
Abstract
BACKGROUND The beneficial effect of biofeedback therapy (BFT) over a period of more than 2 years has not been studied in a large group of patients. The aim of this study was to evaluate the long-term efficacy of BFT for dyssynergic defecation (DD). METHODS We evaluated the results for 347 consecutive constipated patients with DD who underwent BFT for a median of five sessions between 2004 and 2009. Initial responses were assessed immediately after the completion of BFT. A responder was defined as a subject with at least a three-point improvement from before to after BFT on an 11-point global bowel satisfaction (GBS) scale, or a two-point improvement if the baseline GBS was more than six points. The probability of remaining a responder was estimated by non-parametric maximum likelihood estimation. KEY RESULTS The initial response rate to BFT was 72.3% (n = 251), Parkinson's disease and higher baseline GBS scores were associated with initial non-response. The long-term efficacy of BFT was analyzed in 103 patients who were followed up for more than 6 months; the initial effects of BFT were maintained in 85 of the patients (82.5%) during a median of 44 months of follow-up (IQR = 12-68). The probability of remaining a responder was 60% at 2 years, and 58% at 5 years. CONCLUSIONS & INFERENCES The efficacy of BFT is maintained for more than 2 years after BFT in a considerable proportion of constipated patients with DD. BFT is effective and durable treatment for managing DD.

Abstract
Biofeedback therapy is an instrument-based learning process centered on operant conditioning. The goal of biofeedback therapy in defecatory disorders is to strengthen the pelvic floor muscles, retrain rectal sensation and coordinate pelvic floor muscles during evacuation. Biofeedback therapy, in a broader sense, includes education, counseling, and diaphragmatic muscle training as well as exercise, sensory, and coordination training. For dyssynergic defecation, biofeedback therapy is a well-known and useful treatment option that had response rates of approximately 70-80% in randomized controlled trials. Biofeedback therapy for dyssynergic defecation consists of improving the abdominal push effort together with biofeedback technique-guided pelvic floor relaxation followed by simulated defecation and/or sensory training. For fecal incontinence, the results of a randomized controlled trial, which had a response rate of 76%, indicated that biofeedback therapy is useful in selected patients who fail to respond to conservative treatment and that training to enhance rectal discrimination of sensation may be helpful in reducing fecal incontinence. The focus of biofeedback therapy for fecal incontinence is on exercising external sphincter contractions under instant feedback, either alone or synchronously with rectal distension and/or sensory training. Biofeedback therapy is a safe treatment that may produce durable improvement beyond the active treatment period; however, a well-designed study to establish a standard protocol for biofeedback therapy is needed. This review discusses the technique of biofeedback therapy to achieve the goal and clinical outcomes for constipation and fecal incontinence.
