Optimizing the Utility of Anorectal Manometry for Diagnosis and Therapy: A Roundtable Review and Recommendations.

BACKGROUND & AIMS: Anorectal manometry (ARM) is a comprehensive diagnostic tool for evaluating patients with constipation, fecal incontinence, or anorectal pain; however, it is not widely utilized for reasons that remain unclear. The aim of this roundtable discussion was to critically examine the current clinical practices of ARM and biofeedback therapy by physicians and surgeons in both academic and community settings. METHODS: Leaders in medical and surgical gastroenterology and physical therapy with interest in anorectal disorders were surveyed regarding practice patterns and utilization of these technologies. Subsequently, a roundtable was held to discuss survey results, explore current diagnostic and therapeutic challenges with these technologies, review the literature, and generate consensus-based recommendations. RESULTS: ARM identifies key pathophysiological abnormalities such as dyssynergic defecation, anal sphincter weakness, or rectal sensory dysfunction, and is a critical component of biofeedback therapy, an evidence-based treatment for patients with dyssynergic defecation and fecal incontinence. Additionally, ARM has the potential to enhance health-related quality of life and reduce healthcare costs. However, it has significant barriers that include a lack of education and training of healthcare providers regarding the utility and availability of ARM and biofeedback procedures, as well as challenges with condition-specific testing protocols and interpretation. Additional barriers include understanding when to perform, where to refer, and how to use these technologies, and confusion over billing practices. CONCLUSIONS: Overcoming these challenges with appropriate education, training, collaborative research, and evidence-based guidelines for ARM testing and biofeedback therapy could significantly enhance patient care of anorectal disorders.

The psychological and physiological effects of integrated cognitive-behavioral and biofeedback therapy on panic disorder: A randomized controlled trial.

BACKGROUND: Cognitive-behavioral therapy (CBT) and biofeedback therapy are commonly regarded as effective treatment modalities for panic disorder. The aim of this study was to establish a Taiwanese version of an integrated cognitive-behavioral and biofeedback therapy (ICB) and examine its effects on panic disorder using psychological and physiological indicators. METHODS: Thirty patients with panic disorder were enrolled in this study. They were randomly assigned to either the ICB group (n = 15) or the treatment as usual (TAU) group (n = 15). The intervention consisted of six sessions, conducted once a week. Psychological indicators were measured at baseline (prior to intervention), week 3, and week 6, while physiological indicators were measured at baseline and week 6. The psychological indicators included five scales, with the Panic Disorder Severity Scale (PDSS) being the primary measure. The physiological indicators included respiratory sinus arrhythmia (RSA) and skin conductance, which respectively represent parasympathetic and sympathetic activity. RESULTS: Considering all participants, PDSS scores significantly decreased over time, but the difference between the ICB and TAU groups did not reach statistical significance. Among the physiological indicators, resting-state RSA and RSA under relaxation showed significant between-group differences over time, with the ICB group demonstrating a more pronounced improvement in RSA. CONCLUSION: In the context of existing pharmacological treatments, the benefits of ICB for panic disorder may not be observable through psychological indicators. However, it can lead to enhancement of parasympathetic activity as evidenced by the physiological indicators.

Abdomino-anal Dyscoordination in Defecatory Disorders.

BACKGROUND & AIMS: The contribution of the abdominal muscles to normal defecation and disturbances thereof in defecatory disorders (DDs) are unknown. METHODS: In 30 healthy and 60 constipated women with normal rectal balloon expulsion time (BET) (n = 26) or prolonged BET (ie, DD; n = 34), seated anorectal pressures (manometry) and thickness (ultrasound) of the external and internal oblique and transversus abdominis muscles were measured simultaneously at rest, during hollowing, squeeze, evacuation, and a Valsalva maneuver. RESULTS: Compared with healthy women with a normal BET, DD women had a lower rectal and greater anal pressure increase during evacuation (P ≤ .05), and more activation of the internal oblique and the transversus abdominis muscles during squeeze (P < .05). The change in transversus abdominis thickness during a Valsalva maneuver vs hollowing (rho = 0.5; P = .002) and separately vs evacuation (rho = 0.7; P < .0001) were correlated in DD but not in healthy women with a normal BET. A principal component (PC) analysis of anorectal pressures and muscle thicknesses during evacuation uncovered a PC (PC3) that was associated with a prolonged BET. Higher PC3 scores were associated with low rectal and high anal pressures at rest and during evacuation, thinner external oblique muscle, and thicker internal oblique muscle during evacuation. A greater PC3 score was associated with increased odds for DD vs health (odds ratio, 1.84; 95% CI, 1.05-3.23), and separately vs constipation with a normal BET (odds ratio, 3.64; 95% CI, 1.73-7.69). CONCLUSIONS: Taken together, these findings show 3, possibly inter-related, disturbances suggestive of dyscoordination in DD: aberrant activation of abdominal muscles during squeeze in DD, dyscoordination of the abdominal muscles during various tasks in constipated women, and abdomino-anal dyscoordination.

The Efficacy of Biofeedback Therapy in Patients with Solitary Rectal Ulcer and Dyssynergic Defecation.

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.

Efficacy of a Modified Training Program of Adaptive Biofeedback Therapy for Dyssynergic Defecation in Patients with Chronic Constipation.

BACKGROUND: Biofeedback therapy is highly effective and safe in treating dyssynergic defecation, which affects more than half of patients with chronic constipation. However, conventional biofeedback training has limitations. AIMS: This study aims to modify the adaptive biofeedback (ABF) previously established by the investigators and evaluate its efficacy for dyssynergic defecation. METHODS: A total of 42 constipation patients were enrolled and randomly assigned to receive either 4-week adaptive biofeedback (ABF) training (ABF group), or fixed biofeedback (FBF) training (FBF group). The ABF training program was modified, as follows: (1) the tailored training targets were set according to the ability of the individual subject, instead of the fixed values; (2) the outcome was scored on the basis of the rectal-anal pressure gradient; (3) the feedback information was delivered through multimedia. The outcomes were compared between the two groups. RESULTS: The number of weekly bowel movements (BM) was significantly greater in the ABF group than in the FBF group. The improvement in dyssynergic defecation was also noted with the modified ABF training, which performed significantly better than the conventional training on incomplete defecation, bloating, defecation time, staining, and urgency. Notably, the use of medications was significantly reduced upon completion of the 4-week adaptive training, and this was significantly lesser than that in the fixed training. Furthermore, there was significantly better improvement on anorectal motility and rectal sensation in the ABF group vs. the FBF group. CONCLUSION: The modified ABF training program significantly improves constipation-related symptoms, and its performance is superior to conventional FBF training for dyssynergic defecation.

New Internet of Medical Things for Home-Based Treatment of Anorectal Disorders.

Home-based healthcare provides a viable and cost-effective method of delivery for resource- and labour-intensive therapies, such as rehabilitation therapies, including anorectal biofeedback. However, existing systems for home anorectal biofeedback are not able to monitor patient compliance or assess the quality of exercises performed, and as a result have yet to see wide spread clinical adoption. In this paper, we propose a new Internet of Medical Things (IoMT) system to provide home-based biofeedback therapy, facilitating remote monitoring by the physician. We discuss our user-centric design process and the proposed architecture, including a new sensing probe, mobile app, and cloud-based web application. A case study involving biofeedback training exercises was performed. Data from the IoMT was compared against the clinical standard, high-definition anorectal manometry. We demonstrated the feasibility of our proposed IoMT in providing anorectal pressure profiles equivalent to clinical manometry and its application for home-based anorectal biofeedback therapy.

MORE EVIDENCE IS NEEDED TO DETERMINE THE EFFECTIVENESS OF FULL OCCLUSION BIOFEEDBACK SPLINTS USED FOR SLEEP BRUXISM (SB) AND TEMPOROMANDIBULAR DISORDER (TMD) PAIN.

[Regenerative effect of comprehensive physiotherapeutic programs in the early postoperative period in patients with chronic paraproctitis]. / Regenerativnyi effekt primeneniya kompleksnykh fizioterapevticheskikh programm v rannem posleoperatsionnom periode u bol'nykh khronicheskim paraproktitom.

The modern lifestyle is often associated with low physical activity and blood stasis in the pelvic organs, which leads to increased incidence of proctological diseases, and increasingly in people of young working age. Chronic paraproctitis is the third most common proctological disorder that requires surgical treatment. The disease occurs commonly in the age group of 30-50 years, predominantly in men, which determines its socio-economic significance. It indicates the urgent need for advanced comprehensive physiotherapeutic programs for early rehabilitation of patients after surgery for chronic paraproctitis, and the application of new diagnostic technologies for assessment of surgery effectiveness and postoperative changes to provide adequate and effective medical rehabilitation. One of the main goals in the early postoperative period is the acceleration of adequate scar formation and reduction of the postoperative wound healing time; therefore, it seems reasonable to assess regeneration processes using transrectal ultrasound examination and sonoelastography of the scar tissue, which have great potential for use in coloproctology. OBJECTIVE: To study the role of the medical rehabilitation program in the early postoperative period on the adequate scar formation and postoperative wound healing processes (by transrectal ultrasound investigation and scar tissue sonoelastography) as well as postoperative complications rate and long-term (up to 12 months) treatment outcomes in patients with chronic paraproctitis. MATERIAL AND METHODS: The study included 60 patients 20-69 years with chronic pararectal fistulas (ICD-10: K60.4). The patients were assigned into two groups. The control group consisted of 30 patients who received standard of care in the early postoperative period, including analgesics, local antibacterial ointments (Levomekol, etc.), and rectal suppositories (Relief Pro, etc.). The main group also consisted of 30 patients who received standard of care and a 5-day comprehensive physiotherapeutic program starting the second day after the surgery. Effectiveness was assessed by complex transrectal ultrasound investigation with color Doppler mapping, Doppler sonography, and sonoelastography at various post-surgery time points. RESULTS: The higher efficacy of the rehabilitation program, including intravenous ozone therapy, rectal laser therapy, recto-tibial myostimulation, and biofeedback therapy in the early postoperative period, versus the standard of care, was shown. CONCLUSION: The introduction of rehabilitation program including intravenous ozone therapy, rectal laser therapy, recto-tibial myostimulation, and biofeedback therapy in the early postoperative period significantly reduced the average postoperative wound healing time by accelerating the formation of an adequate scar (according to transrectal ultrasound investigation and scar tissue sonoelastography) and the incidence of postoperative complications and improved the long-term treatment outcomes (up to 12 months) in patients with chronic paraproctitis.

[Non-drug technologies in early rehabilitation of patients after hemorrhoidectomy]. / Nemedikamentoznye tekhnologii v rannei reabilitatsii bol'nykh posle gemorroidektomii.

Among all coloproctological diseases, hemorrhoids rank first among the reasons for visiting a proctologist. Its prevalence is 130-145 per 1.000 adults, and its proportion in the structure of colorectal diseases ranges from 34 to 41%. After hemorrhoidectomy, a long period of rehabilitation is necessary. There are long periods of incapacity for work (at least two weeks) and quite high complications rate, which generally leads to economic burden. Therefore, an urgent problem of current coloproctology and physiotherapy is the development of new approaches to medical rehabilitation of the patients after surgery for their fast recovery and prevention of complications. OBJECTIVE: To study effectiveness of comprehensive postoperative rehabilitation program including ozone therapy, laser therapy, recto-tibial myostimulation and biofeedback therapy in patients after hemorrhoidectomy. MATERIAL AND METHODS: The study included 90 patients 20-65 years of age (mean age 41.4±2.1years) with chronic stage III hemorrhoids with prominent external nodules (ICD-10 code: K64.2). All patients underwent Milligan-Morgan hemorrhoidectomy using an ultrasound scalpel by the same coloproctologist to exclude the influence of personality factors. The patients were assigned into two groups by random sampling. The main group consisted of 45 patients who received standard of care and the rehabilitation program, including intravenous ozone therapy, rectal laser therapy, recto-tibial myostimulation, and biofeedback therapy starting from the second day after the surgery. The control group consisted of 45 patients who received the same standard of care in the early postoperative period, including analgesics, local antibacterial ointments (Levomekol, etc.), and rectal suppositories (Relief Pro, etc.). RESULTS: In the early postoperative period, in the patients who received non-drug rehabilitation program, the pain was significantly less intensive, and it relieved faster after surgery, which indicated a strong analgesic effect of the rehabilitation program. Patients in the control group received analgesics (including narcotic drugs) for pain control in 68.9% of cases. Duration of postoperative incapacity for work in the main group patients was 12.9±2.4 days vs. 24.1±2.3 days in the control group patients (p<0.001). The analysis of the quality of life in the early and the late postoperative period by SF-36 scale showed a significant difference between the groups according to the physical health component and psychological component both in the early and in the late postoperative period (after six months), which indicates the higher quality of life in the main group patients. Assessment of the late period quality of life using the I. Yu. Alimzhanova and Yu.M. Sheptunov questionnaire showed good results in 43 (95.6%) patients of the main group. Only in 2 (4.4%) main group patients, anal stenosis was observed. Good results were shown in 38 (84.58%) control group patients. Seven patients had complications: cicatricial anal stenosis (5 [11.1%] patients) and pararectal fistulas (2 [4.4%] patients); in 3 (42.9%) of these 7 patients a persistent pain syndrome was developed. CONCLUSIONS: Introduction of the rehabilitation program in the early postoperative period after hemorrhoidectomy contributes to faster relief of pain and other signs and symptoms, a significant decrease of average postoperative wound healing time due to acceleration of adequate scar formation (according to ultrasound sonoelastography), improvement of life quality, reduction of hospital stay, a decrease of incapacity for work duration, and prevention of postoperative complications.

Effect of treatment with a full-occlusion biofeedback splint on sleep bruxism and TMD pain: a randomized controlled clinical trial.

OBJECTIVES: The purpose of the present study was to analyze treatment outcome with a full-occlusion biofeedback (BFB) splint on sleep bruxism (SB) and TMD pain compared with treatment with an adjusted occlusal splint (AOS). MATERIALS AND METHODS: Forty-one patients were randomly allocated to a test (BFB) or a control (AOS) group and monitored over a 3-month period. Output variables were frequency and duration of bruxing events (bursts) and various pain symptoms. RESULTS: The BFB group showed a statistically significant reduction in the frequency and duration of bursts and a statistically significant improvement in the patients' global well-being and the facial muscle pain parameter. After the treatment was stopped, the BFB group showed a statistically significant reduction in the average and maximum duration but no statistically significant change in the frequency of bursts. CONCLUSIONS: The tested BFB splint is highly effective in reducing SB at the subconscious level, i.e., without waking the patient, and in achieving improvements in global pain perception. The results suggest that the BFB splint also provides a better treatment option for bruxism-related pain than an AOS. However, further research is needed, and specifically studies with a larger patient population displaying higher levels of pain at baseline. CLINICAL RELEVANCE: By reducing burst duration and therefore the pathological load on the masticatory apparatus, the BFB splint reduces TMD and bruxism-related symptoms and improves patients' physical well-being. In the long term, this could prevent damage to the TMJ. This study confirms the effectiveness and safety of this splint.

Non-pharmacological Interventions for Intractable Epilepsy.

In 30% of epileptic individuals, intractable epilepsy represents a problem for the management of seizures and severely affects the patient's quality of life due to pharmacoresistance with commonly used antiseizure drugs (ASDs). Surgery is not the best option for all resistant patients due to its post-surgical consequences. Therefore, several alternative or complementary therapies have scientifically proven significant therapeutic potential for the management of seizures in intractable epilepsy patients with seizure-free occurrences. Various non-pharmacological interventions include metabolic therapy, brain stimulation therapy, and complementary therapy. Metabolic therapy works out by altering the energy metabolites and include the ketogenic diets (KD) (that is restricted in carbohydrates and mimics the metabolic state of the body as produced during fasting and exerts its antiepileptic effect) and anaplerotic diet (which revives the level of TCA cycle intermediates and this is responsible for its effect). Neuromodulation therapy includes vagus nerve stimulation (VNS), responsive neurostimulation therapy (RNS) and transcranial magnetic stimulation therapy (TMS). Complementary therapies such as biofeedback and music therapy have demonstrated promising results in pharmacoresistant epilepsies. The current emphasis of the review article is to explore the different integrated mechanisms of various treatments for adequate seizure control, and their limitations, and supportive pieces of evidence that show the efficacy and tolerability of these non-pharmacological options.

Pelvic floor biofeedback therapy in children: Assessment of symptom scores in responders and non-responders.

INTRODUCTION: Pelvic Floor Biofeedback Therapy (PFBT) can be an effective treatment for pediatric lower urinary tract symptoms (LUTS). Due to differing perceptions of efficacy and practice patterns, we sought to further evaluate PFBT in our practice. We hypothesized that PFBT results in quiescence of EMG activity during voiding and improves questionnaire scores in patients with LUTS. METHODS: We retrospectively reviewed all patients undergoing PFBT and refined the analysis to females ≥6 years old with ≥2 sessions with completed voiding questionnaires pre- and post-treatment, active EMG during voiding, with non-neurogenic urinary tract complaints refractory to standard urotherapy. Validated Bladder Bowel Dysfunction (BBD) questionnaires were collected at each visit. Quiescence of EMG activity and changes in BBD score were the primary outcomes. RESULTS: 229 patients underwent ≥1 PFBT session, of which 64 females ≥6 years of age with ≥2 PFBT sessions and completed pre and post PFBT voiding questionnaires were identified. In this group, mean age at PFBT start was 10.1 (6.2-17.0). Patients completed 3.1 sessions (2-6). No difference was seen in post-void residual (PVR) between first and last session (23.8 vs 22.6 mL, P = 0.55). Median questionnaire score decreased from 18 (4-42) before to 13 (2-28) following PFBT (P < 0.0001). Responders, characterized by silencing of the EMG after PFBT, occurred in 31% (20/64). Non-responders were younger (P = 0.007) with higher pre-PFBT questionnaire scores. CONCLUSION: The use of PFBT appears to result in a significant reduction in symptom scores, though quiescence of EMG was observed following therapy in less than 1/3 of patients.

Three-dimensional high-resolution anorectal manometry can predict response to biofeedback therapy in defecation disorders.

PURPOSE: Biofeedback therapy (BT) is a simple and effective technique for managing outlet constipation and fecal incontinence. Several clinical factors are known to predict BT response, but a 50% failure rate persists. Better selection of BT responsive patients is required. We aimed to determine whether the defecation disorder type per high-resolution manometry (HRM) was predictive of BT response. METHODS: We analyzed clinical, manometric, and ultrasound endoscopic data from patients who underwent BT in our department between January 2015 and January 2016. Patients were classified into four groups per the following defecation disorder classification criteria: rectal pressure > 40 mmHg and anal paradoxical contraction (type I); rectal pressure < 40 mmHg and anal paradoxical contraction (type II); rectal pressure > 40 mmHg and incomplete anal relaxation (type III); and rectal pressure < 40 mmHg and incomplete anal relaxation (type IV). An experienced single operator conducted ten weekly 20-min sessions. Efficacy was evaluated with the visual analog scale. RESULTS: Of 92 patients, 47 (50.5%) responded to BT. Type IV and type II defecation disorders were predictive of success (p = 0.03) (OR = 5.03 [1.02; 24.92]) and failure (p = 0.05) (OR = 0.41 [0.17; 0.99]), respectively. The KESS score severity before BT (p = 0.03) (OR = 0.9 [0.81; 0.99]) was also predictive of failure. CONCLUSION: The manometry types identified according to the defecation disorder classification criteria were predictive of BT response. Our data confirm the role of three-dimensional HRM in the therapeutic management of anorectal functional disorders.

Decreased electrodermal activity in patients with epilepsy.

OBJECTIVE: Biofeedback therapy using electrodermal activity (EDA) is a new noninvasive therapy for intractable epilepsy. However, the characteristics of EDA in patients with epilepsy are little known; therefore, we assessed the EDA characteristics in patients with epilepsy. METHODS: A cross-sectional observational study was conducted in 22 patients with epilepsy and 24 healthy individuals. We collected information on demographic characteristics, EDA, and state anxiety from both groups, and epilepsy diagnosis, seizure number per month, disease duration, and number of antiepileptic drugs (AED) from the epilepsy group. A wristband device was used to measure resting EDA from both wrists for 10 min under controlled temperature and humidity. We compared the EDA levels between the epilepsy group and the control group and examined correlations between EDA and epilepsy-associated factors in the epilepsy group. RESULTS: A decreasing trend in EDA was observed during the first 1 min from the start of the measurement in 22 patients with epilepsy (with or without seizures) compared with healthy controls (P = 0.12). However, a significant decrease in EDA was found in 18 patients with epilepsy with seizures compared with healthy controls (-0.48 versus -0.26; P = 0.036). Furthermore, seizure frequency showed a significant inverse correlation with EDA in the epilepsy group (ρ = -0.50, P = 0.016). However, neither disease duration nor the number of drugs prescribed correlated with EDA in the epilepsy group . SIGNIFICANCE: Marginally decreased EDA was observed in patients with epilepsy, and significantly decreased EDA was found in patients with a higher seizure frequency. The present findings shed light on the appropriateness of EDA-biofeedback therapy in epilepsy.

A Practical Guide to Biofeedback Therapy for Pelvic Floor Disorders.

PURPOSE OF REVIEW: Biofeedback therapy (BFT) is effective for managing pelvic floor disorders (i.e., defecatory disorders and fecal incontinence). However, even in controlled clinical trials, only approximately 60% of patients with defecatory disorders experienced long-term improvement. The review serves to update practitioners on recent advances and to identify practical obstacles to providing biofeedback therapy. RECENT FINDINGS: The efficacy and safety of biofeedback therapy have been evaluated in defecatory disorders, fecal incontinence, and levator ani syndrome. Recent studies looked at outcomes in specific patient sub-populations and predictors of a response to biofeedback therapy. Biofeedback therapy is effective for managing defecatory disorders, fecal incontinence, and levator ani syndrome. Patients who have a lower bowel satisfaction score and use digital maneuvers fare better. Biofeedback therapy is recommended for patients with fecal incontinence who do not respond to conservative management. A subset of patients with levator ani syndrome who have dyssynergic defecation are more likely to respond to biofeedback therapy.

Functional Anorectal Disorders.

This report defines criteria and reviews the epidemiology, pathophysiology, and management of common anorectal disorders: fecal incontinence (FI), functional anorectal pain and functional defecation disorders. FI is defined as the recurrent uncontrolled passage of fecal material for at least 3 months. The clinical features of FI are useful for guiding diagnostic testing and therapy. Anorectal manometry and imaging are useful for evaluating anal and pelvic floor structure and function. Education, antidiarrheals and biofeedback therapy are the mainstay of management; surgery may be useful in refractory cases. Functional anorectal pain syndromes are defined by clinical features and categorized into three subtypes. In proctalgia fugax, the pain is typically fleeting and lasts for seconds to minutes. In levator ani syndrome (LAS) and unspecified anorectal pain the pain lasts more than 30 minutes, but in LAS there is puborectalis tenderness. Functional defecation disorders are defined by >2 symptoms of chronic constipation or irritable bowel syndrome with constipation, and with >2 features of impaired evacuation i.e., abnormal evacuation pattern on manometry, abnormal balloon expulsion test or impaired rectal evacuation by imaging. It includes two subtypes; dyssynergic defecation and inadequate defecatory propulsion. Pelvic floor biofeedback therapy is effective for treating LAS and defecatory disorders.

[The application of the physical factors for the medical rehabilitation of the children presenting with neurogenic dysfunction of the bladder].

This article describes the modern technologies for the medical rehabilitation of the children presenting with neurogenic dysfunction of the bladder aimed at improving the act of urination at all levels of innervation. The most frequent variant of neurogenic dysfunction of the bladder in the children is the hyper-reflexive one; it is this variant in which the most pronounced disorders of urodynamics due to intravesical hypertension and detrusor hypoxia are observed. The urodynamic disorders are known to contribute to the formation of the characteristic clinical picture associated with the hyper-reflexive urinary bladder dysfunction in the children characterized by the mandatory urination syndrome, pollakiuria, imperative urges, and mandatory urinary incontinence in the combination with enuresis. The treatment of urinary bladder dysfunction includes both behavioural and medication therapeutic modalities. The "golden standard" for the pharmacotherapy of neurogenic bladder dysfunction of the hyper-reflexive type in the childhood is the use of M-cholinoblockers, such as oxybutynin. The popularity of the physiotherapeutic methods is attributable to their influence on the main links of pathogenesis, the absence of side effects, and the possibility of application in the children of the early age. The combined treatment of neurogenic bladder dysfunction includes the use of a wide range of physiotherapeutic methods the action of which is aimed at regulating the act of urination at all levels of innervation of the bladder, normalizing the tone of the muscles of the bladder, eliminating sphincter insufficiency, improving circulation and accelerating the maturation of the neuromuscular apparatus of the pelvic organs. At present, the natural and preformed methods of physiotherapy are finding the wide application for the management of neurogenic dysfunction of the bladder in the children in the conjunction with therapeutic physical exercises, massage, and the biological feedback (BFB) technique.

An update on anorectal disorders for gastroenterologists.

Gastroenterologists frequently encounter pelvic floor disorders, which affect 10% to 15% of the population. The anorectum is a complex organ that collaborates with the pelvic floor muscles to preserve fecal continence and enable defecation. A careful clinical assessment is critical for the diagnosis and management of defecatory disorders and fecal incontinence. Newer diagnostic tools (eg, high-resolution manometry and magnetic resonance defecography) provide a refined understanding of anorectal dysfunctions and identify phenotypes in defecatory disorders and fecal incontinence. Conservative approaches, including biofeedback therapy, are the mainstay for managing these disorders; new minimally invasive approaches may benefit a subset of patients with fecal incontinence, but more controlled studies are needed. This mini-review highlights advances, current concepts, and controversies in the area.
