Ropivacaine versus lidocaine infiltration for postpartum perineal pain: A systematic review and meta-analysis.

AIM: To systematically and meta-analytically examine the efficacy of ropivacaine versus lidocaine infiltration for controlling postpartum perineal pain secondary to spontaneous tear or selective episiotomy. METHODS: We searched four databases from inception to 20-September-2020. We included all relevant randomized and nonrandomized studies and assessed their risk of bias. We pooled data as standardized mean difference (SMD), weighted mean difference (WMD), or odds ratio (OR) with 95 % confidence intervals (95 % CIs). RESULTS: Four studies met the inclusion criteria (one and three studies were nonrandomized and randomized, respectively). There were 405 patients; 205 and 200 patients received lidocaine and ropivacaine, respectively. There was no significant difference between ropivacaine and lidocaine groups with regard to visual analogue scale (VAS) pain scores at suturing (WMD = -0.04, 95 % CI [-0.41, 0.32], P = 0.82), 2 h (SMD = -1.50, 95 % CI [-3.50, 0.50], P = 0.14), and 24 h (SMD = -0.40, 95 % CI [-1.15, 0.34], P = 0.29) post repair of perineal trauma. Proportion of patients with mild VAS pain score ≤3 at 24 h was significantly higher in the ropivacaine group (OR = 4.34, 95 % CI [2.03, 9.29], P < 0.001). Proportion of patients who did not require additional analgesia during the first 24 h post perineal repair did not significantly differ between both groups (OR = 2.44, 95 % CI [0.09, 68.21], P = 0.60). Ropivacaine group achieved higher maternal satisfaction (OR = 7.13, 95 % CI [3.63, 13.99], P < 0.001). CONCLUSIONS: During repair of postpartum perineal trauma, pain efficacy is relatively longer with ropivacaine but safety is not well investigated. High-quality and large-sized studies are needed to consolidate these findings.

[Methods of preventing perineal injury and dysfunction during pregnancy: CNGOF Perineal prevention and protection in obstetrics]. / Quelles interventions au cours de la grossesse diminuent le risque de lésions périnéales ? RPC Prévention et protection périnéale en obstétrique CNGOF.

OBJECTIVE: Several interventions during pregnancy have been described that might prevent the risk of postnatal perineal injury or dysfunction; these include prenatal perineal massage, use of the Epi-No device, and pelvic floor muscle training exercises. Our objective was to evaluate the effectiveness of these different interventions during pregnancy. METHODS: A systematic review of the literature was conducted on PubMed, including articles in French and English published before May 2018, to evaluate the effectiveness of these different interventions on perineal protection in the post-partum period. RESULTS: Perineal massage during pregnancy diminishes the episiotomy rate (LE1) as well as post-partum perineal pain and flatus (LE2). It does not reduce the rate of either OASIS (LE1) or post-partum urinary incontinence (LE2). The Epi-No device does not provide benefits for perineal protection (LE1). Prenatal pelvic floor muscle training exercises do not reduce the risk of perineal lacerations (LE2); they reduce the prevalence of post-partum urinary incontinence at 3 to 6 months but not at 12 months post-partum (LE2). CONCLUSION: Perineal massage during pregnancy must be encouraged among women who want it (Grade B). The use of the Epi-No device during pregnancy is not recommended for the prevention of OASIS (grade B). Pelvic floor muscle training during pregnancy is not recommended for the prevention of OASIS (grade B); moreover, its absence of effect in the medium term does not allow us to recommend it for urinary incontinence (professional consensus).

A Randomized, Controlled Clinical Study to Assess the Effect of Anodal and Cathodal Electrical Stimulation on Periwound Skin Blood Flow and Pressure Ulcer Size Reduction in Persons with Neurological Injuries.

The use of electrical stimulation (ES) should be considered for treating nonhealing pressure ulcers (PUs), but optimal ES wound treatment protocols have yet to be established. A randomized, controlled, double-blind clinical study was conducted to evaluate the effects of cathodal and anodal high-voltage monophasic pulsed current (HVMPC) on periwound skin blood flow (PSBF) and size reduction of Stage 2 to Stage 4 PUs of at least 4 weeks' duration. Persons >18 years of age, hospitalized with neurological injuries, at high risk for PU development (Norton scale <14 points; Waterlow scale >15 points), and with at least 1 Stage 2 to Stage 4 PU were eligible to participate in the study. Persons with necrotic wounds, osteomyelitis, electronic or metal implants in the PU area, PUs in need of surgical intervention, acute wound inflammation, diabetes (HBA1c >7%), diabetic neuropathy, cancer, and/or allergies to standard wound treatments were excluded. Patients were randomly assigned to 1 of 3 groups: anodal (AG), cathodal (CG), or placebo (PG) ES. All groups received individualized PU prevention and standard wound care. In the PG, sham ES was applied; the AG and CG were treated with anodal and cathodal HVMPC, respectively (154 µs 100 Hz; 360 µC/second; 1.08 C/day), 50 minutes per day, 5 days per week, for a maximum of 8 weeks. PSBF was measured using laser Doppler flowmetry at baseline, week 2, and week 4, and wound surface area measurements were obtained and analyzed using a digitizer connected to a personal computer. Data analysis utilized the maximum-likelihood chi-squared test, the analysis of variance Kruskal-Wallis test, the Kruskal-Wallis post-hoc test, and Spearman's rank order correlation. Nonlinear approximation based on exponential function was used to calculate treatment time needed to reduce the wound area by 50%. In all tests, the level of significance was set at P ≤.05. Of the 61 participating patients, 20 were in the AG (mean age 53.2 ± 13.82 years), 21 in the CG (mean age 55.67 ± 17.83 years), and 20 in the PG (mean age 52.5 ± 13.18 years). PUs (baseline size range 1.01 cm2 to 59.57 cm2; duration 4 to 48 weeks) were most frequently located in the sacral region (73.77%) and classified as Stage 3 (62.29%). PSBF at week 2 was significantly higher in the AG and CG than in the PG (P <.05). Week 4 differences were not statistically significant. Wound percentage area reduction calculated at week 8 for the AG (64.10% ± 29.22%) and CG (74.06% ± 23.23%) were significantly different from PG ulcers (41.42% ± 27.88%; P = .0391 and P = .0024, respectively). In both ES groups, PSBF at week 4 and percent wound surface area reductions between weeks 4 and 8 were positively correlated, but only the AG correlation was statistically significant (P = .049). In this study, both ES modalities improved blood flow and wound area reduction rate. Studies examining optimal ES treatment times for healing to occur, the effect of comorbidities and baseline wound variables on ES outcomes, and the nature of the relationship between blood flow and healing are necessary.

Short-term outcome of percutaneous tibial nerve stimulation for low anterior resection syndrome: results of a pilot study.

AIM: Percutaneous tibial nerve stimulation (PTNS) is a minimally invasive procedure which has been demonstrated to be effective in faecal/urinary incontinence but has never been tested in low anterior resection syndrome (LARS). The severity of LARS may be evaluated by the LARS score, but rectal cancer treatments may also affect urinary and sexual function, which are not explored by the LARS score. The Three Axial Perineal Evaluation (TAPE) score is a new validated index addressing the overall pelvic floor functions. This study aims to assess the efficacy of PTNS in LARS patients and to evaluate the results by the LARS and TAPE scores. METHODS: Twenty-one patients operated on for rectal cancer between 2009 and 2014 complaining of LARS underwent PTNS (12 sessions of 30 min each). Six patients reported urinary incontinence and all except two (men) were sexually inactive. The LARS score and the TAPE score questionnaires were administered at baseline and after 6 months of follow-up. RESULTS: At 6 months' follow-up, nine patients reported a significant improvement of faecal incontinence and 3/6 an improvement of urinary incontinence after PTNS. Median LARS score significantly decreased from 32 to 27 (P = 0.009), while the median TAPE score improved significantly from 55 to 58 (P = 0.004). CONCLUSIONS: PTNS may be a further option in the treatment of selected patients with LARS and in addition may improve associated urinary incontinence. The severity of LARS can be detected by the LARS score; however, the adoption of the TAPE score is preferred in the case of concomitant urinary and/or sexual problems not explored by the LARS score.

Comparison of the efficacy of perineal and intravaginal biofeedback assisted pelvic floor muscle exercises in women with urodynamic stress urinary incontinence.

OBJECTIVE: To assess the effectiveness of intravaginal pressure biofeedback (P-BF) and perineal electromyographic biofeedback (EMG-BF) assisted pelvic floor muscle (PFM) exercises in women with stress urinary incontinence (SUI). MATERIAL AND METHODS: Fifty-three women with SUI were randomized into three groups as follows: the Group 1 received PFM home exercise program alone (n:18); the Group 2 received PFM home exercise program plus intravaginal P-BF assisted PFM exercise program (n:17); and the Group 3 received PFM home exercise program plus perineal EMG-BF assisted PFM exercise program (n:18). Subjects were also assessed with the 1-h pad test (severity of incontinence), perineometer (PFM strength), social activity index (SAI), IIQ7 (quality of life associated with incontinence), treatment success (cure and improvement rate) and treatment satisfaction. RESULTS: A statistically significant improvement was found in all parameters for all groups at 4th week and 8th week compared to the baseline values. It was found that severity of incontinence, PFM strength, and SAI scores were significantly improved in both BF groups compared to the Group 1 at 8th week. Also, statistically higher cure and improvement rate and treatment satisfaction values were detected in both BF groups compared to the Group 1. There was no statistically significant difference between Group 2 and Group 3 in all parameters evaluated at the follow-up period. CONCLUSIONS: We conclude that both the home exercises plus intravaginal P-BF and home exercises plus perineal EMG-BF are superior to home exercises in women with SUI. Intravaginal P-BF and perineal EMG-BF were similarly effective and they can be used as their alternatives.

Eficácia do Epi-No® na diminuição da episiotomia e risco de lesão perineal pós-parto: revisão sistemática / Effectiveness of Epi-No® in decline episiotomy and risk of injury perineal postpartum: systematic review

A pergunta mais clássica das gestantes ou futuras mães seria qual tipo de parto escolher. Para as que pretendem ter parto normal, o desejo é ter seu períneo íntegro após o parto. Como a taxa de episiotomia aumentou consideravelmente, e atualmente é a operação cirúrgica mais frequente em mulheres no mundo, surge à necessidade de pesquisar quais métodos seriam capazes de minimizar ou evitar esse procedimento. Este estudo objetivou avaliar a eficácia de um aparelho em forma de balão que infla com ajuda de um medidor de pressão denominado Epi-No® na redução da necessidade de episiotomia e na diminuição do risco de lesão pós-parto. Foi realizada uma revisão sistemática da literatura, de estudos clínicos randomizados, que investigassem os efeitos do Epi-No® levantados no período de 24 a 30 de setembro de 2014 através das palavras-chave. Inicialmente foram encontrados 1.149 artigos, seguindo os critérios de inclusão e exclusão, o número foi reduzido, sendo analisados 6 artigos neste estudo. Conclui-se então que o uso do Epi-No® parece ser eficaz na redução de episiotomia e lesões pós-parto, no entanto são necessários mais estudos controlados randomizados com maiores números amostrais para determinar melhor a sua eficácia.(AU)

The most classic question of pregnant women or future mothers is: which type of delivery to choose? For those who intend to take normal delivery, the desire is that the perineum remain integrate after delivery. Since episiotomy rate has increased considerably and is currently the most common surgical procedure in women in the world, comes the need to know which methods would be effective to prevent it. This study aimed to evaluate the effectiveness of a balloon-like device that inflates with the help of a pressure gauge known as Epi-No® in reducing the need for episiotomy and decreased risk of postpartum injury. A systematic literature review was performed with randomized clinical trials to investigate the effects of Epi-No®, from September 24 to 30, using keywords. Initially, were found 1.149 articles, following the inclusion and exclusion criteria, the number was reduced and 6 articles wer analyzed in this study. The conclusion is that Epi-No® appears to be effective in reducing episiotomy and postpartum injuries, but we need more randomized controlled trials with larger sample numbers to better determine their effectiveness.(AU)

[Descending perineum syndrome in children: Pathophysiology and diagnosis].

Objective: To propose a safer, simpler, and more exact method for the diagnosis of descending perineum syndrome (DPS). Material and Methods: A total of 194 patients aged 5 days to 15 years were examined and divided into 2 groups: Group 1 consisted of 65 patients without anorectal anomalies (AA); Group 2 comprised 129 patients, including 66 children with functional constipation, 55 with AA and visible fistulas, who were preoperatively examined, and 8 patients with anorectal angle (ARA), who were postoperatively examined. All the patients underwent irrigoscopy that was different from standard examination in the presence of X-ray CT contrast marker near the anus. Results and Conclusion: DPS is caused by puborectalis muscle dysfunction. A method was proposed to evaluate the status of the puborectalis muscle from the distance between the position of the ARA and the marker near the anus. This not only promotes an exacter estimate of DPS, but also allows refusal of defecography. The use of a barium enema with the minimum number of X-ray films decreases dose of ionizing radiation hazard and permits the use of this procedure not only in adults, but also in children with chronic constipation, fecal incontinence, and in AA for both pre- and postoperatively assessment of the causes of complications.

[Multicentric prospective randomized study evaluating the interest of intravaginal electro-stimulation at home for urinary incontinence after prior perineal reeducation. Interim analysis]. / Étude prospective multicentrique randomisée évaluant l'intérêt de l'électrostimulation intravaginale à domicile après rééducation périnéale pour incontinence urinaire. Analyse intermédiaire.

OBJECTIVES: Perineal reeducation of stress urinary incontinence is beneficial in 80% of cases. However, patients have to perform self-retraining exercises of the perineal muscles at home, in order to maintain the benefit of the physiotherapy. The aim of this study is to assess the benefit of GYNEFFIK(®), a perineal electro-stimulator, during this home-care phase. PATIENTS AND METHODS: Women with stress urinary incontinence (UI) or with mixed UI (composed predominantly of stress UI) that responded to physiotherapy were included in this study in two parallel groups. The groups followed a self-reeducation program, with or without GYNEFFIK(®) electro-stimulation sessions. The comparison of the two groups was based on the rate of women for whom the benefit of the initial perineal reeducation was maintained (defined as non-worsening ICIQ and Ditrovie scales' score). RESULTS: According to the protocol, an interim analysis was performed on 95 patients (i.e. almost half of the expected sample size) who had had at least one evaluation under treatment, among which 44 patients had finished the study. The therapeutic benefit of the initial perineal reeducation was maintained in 87.8% of the GYNEFFIK(®) patient group, while it was maintained in 52.2% (P=0.0001) in the usual care group (i.e. who did not use electro-stimulation). DISCUSSION AND CONCLUSION: Likewise, patient had a more favorable subjective impression when using GYNEFFIK(®) (83.7% versus 60.0% in the usual care group) as they felt that they improved during the study. In the GYNEFFIK(®) group, no increase in symptoms was reported, whereas almost one out of five patients in the usual care group felt that their condition had worsened.

Perineal retraining improves conservative treatment for faecal incontinence: a multicentre randomized study.

BACKGROUND: Anal incontinence is a frequent complaint that profoundly affects quality of life. Our aim was to determine whether perineal retraining gives additional benefits to standard medical treatment. METHODS: Patients with anal incontinence and a Wexner score >4 were randomly assigned to standard conservative treatment (control) or perineal retraining, including biofeedback, in addition to standard treatments (biofeedback). Diaries, self-administered questionnaires and satisfaction scores quantified the benefits. Self-evaluated improvement was the primary outcome measure. A score ≥3 (in an improvement scale from -5 to +5) defined success. RESULTS: Overall, 157 patients were included; 80 in the control group (75% females, mean age 60.1 ± 13.2 years) and 77 in the biofeedback group (79% females, mean age 61.9 ± 10.2 years). After a 4-month follow-up, the success rate was significantly higher in the biofeedback group (57% versus 37%; p<0.021). In the biofeedback group, daily stool frequency, leakage, and faecal urgency significantly decreased, and daily non-urgent perception of stool increased. Conversely, symptomatic scores and quality of life scales did not significantly differ between groups. In a multivariate model, the adjusted odds ratio showed that perineal retraining was significantly associated with a higher chance of self-rated improvement (adjusted Odd Ratio [95%CI]: 2.34 [1.14-4.80]; p=0.021). CONCLUSIONS: Perineal retraining offers a moderate but significant benefit for patients suffering from anal incontinence.

The Three Axial Perineal Evaluation (TAPE) score: a new scoring system for comprehensive evaluation of pelvic floor function.

AIM: Abnormalities of one pelvic floor compartment are usually associated with anomalies in the other compartments. Therapies which specifically address one clinical problem may potentially adversely affect other pelvic floor activities. A new comprehensive holistic scoring system defining global pelvic function is presented. METHOD: A novel scoring system with a software program is presented expressing faecal, urinary and gynaecological functions as a geometric polygon based on symptom-specific questionnaires [the three axial pelvic evaluation (TAPE) score] where differences in overall geometric area vary from normal. After validation in healthy volunteers, its clinical performance was tested on patients with obstructed defaecation, genital prolapse and urinary/faecal incontinence treated by the stapled transanal rectal resection (STARR) procedure, colpo-hysterectomy and sacral nerve modulation, respectively. The TAPE score was correlated with the Pelvic Floor Impact Questionnaire 7 quality of life score. RESULTS: There was good inter-observer variation and internal consistency between two observers recording the TAPE score in normal volunteers. In the STARR patients, constipation improved but the TAPE score was unchanged because of deterioration in other pelvic floor functions leading to an unchanged overall postoperative recorded quality of life. Conversely, incontinent patients treated with sacral nerve stimulation improved their function showing concomitant improvements in TAPE scores and quality of life indices. Similar correlative improvements were noted in patients undergoing hysterectomy for genital prolapse. CONCLUSION: The TAPE score defines the impact of symptom-specific treatments on the pelvic floor and may provide an opportunity for comparison of clinical data between units and in clinical trials of specific medical and surgical pelvic floor management.

[Functional proctology at the University of Pécs]. / Funkcionális proktológia a Pécsi Tudományegyetemen.

INTRODUCTION: Functional proctological investigations have been introduced at Pécs University of Sciences 15 years ago. The Pelvic Floor Multidisciplinary Team has been re-launched after many years of pause in 2010. Experience of the team in the treatment of faecal incontinence and obstructed defecation syndrome is discussed. PATIENTS: In the past 3 years 9 patients underwent sphincter reconstruction for faecal incontinence. The Pelvic Floor Team in the past 1.5 year consulted 31 patients with constipation, who were considered by the referee for surgical intervention. Following investigations 10 patients underwent surgery, the rest of them were treated conservatively. Seven patients underwent perineal reconstruction with mesh, three patients had ventral rectopexy with additional levatoro-pexy. RESULTS: 78% of patients operated on for faecal incontinence reported full continence, 88% improvement. We invented a new symptom score with a maximum of 20 points to evaluate results of treatment of patients with Obstructed Defecation Syndrome. Patients who underwent perineal repair were interviewed pre and postoperatively. They scored 14 ± 2.83 and 5.4 ± 4.62 points, respectively (p = 0.0075). CONCLUSION: Functional proctological patients require a specialist approach from history taking through investigation to treatment. Majority of patients benefit from conservative treatment. Adequate patient selection is essential for successful surgical treatment. Symptom scores applied pre and postoperatively facilitate proper patient selection for various surgical methods.

Rectosigmoid tubular duplication presenting as perineal sepsis in a neonate.

Tubular rectal duplication is a very rare congenital anomaly. We report a case of tubular rectal duplication in a newborn baby who presented with perianal sepsis. The diagnosis was confirmed by barium enema, magnetic resonance imaging, and at operation. We performed total mucosectomy through a posterior sagittal incision combined with laparotomy. The patient was doing quite well at 17-month follow-up examination.

Perineal trauma: reducing associated postnatal maternal morbidity.

Perineal tears affect about 85% of women undergoing normal delivery in the UK. The proper understanding of perineal anatomy by midwives and trainee doctors is important for the correct recognition of the severity of tears. Measures to minimise perineal tears include teaching pelvic floor exercise during the third trimester, psychological support during labour and good perineal support during the second stage of labour. To ensure good management, systematic examination of the perineum, vagina, and rectum should be done under good light for all vaginal deliveries. Proper recognition of the degree of tears, selection of suture materials and seeking senior help whenever needed are crucial. Of those women who prefer elective caesarean section rather than vaginal delivery, 80% do so because of the fear of perineal damages. These adverse outcomes can be minimised by training midwives and trainee doctors with surgical skills workshops in the use of models, audiovisual aids, case scenarios and perineal repair simulation exercises.

Male patients with lower urinary tract symptoms. 2: Treatment.

The first part of this article (Dorey, 2000) described the subjective and objective assessment of men with lower urinary tract symptoms (LUTS). This article will examine treatment protocols for stress incontinence, urge incontinence, post-prostatectomy incontinence, post-micturition dribble, overflow incontinence, reflex incontinence and functional incontinence. Pelvic floor muscle exercises, biofeedback, electrical stimulation, urge suppression techniques, and fluid intake are discussed. It is concluded that men with LUTS can benefit from conservative treatment.

Descending perineum syndrome: audit of clinical and laboratory features and outcome of pelvic floor retraining.

OBJECTIVE: Our aim was to retrospectively analyze the Mayo Clinic experience of descending perineum syndrome from 1987-1997. METHODS: Clinical records were abstracted for demographic features, risk factors, results of anorectal and defecation tests, and a mailed questionnaire evaluated outcome and current symptoms. RESULTS: All results are mean +/- SD. Clinically, 39 patients (38 women, one man), mean age 53+/-14 yr, presented with constipation (97%), incomplete rectal evacuation (92%), excessive straining (97%), digital rectal evacuation (38%), and fecal incontinence (15%). Laboratory tests showed anal sphincter resting pressure was 54+/-26 mm Hg, and squeeze pressure was 96+/-35 mm Hg; expulsion from the rectum of a 50-ml balloon required > 200 g added weight in 27%; perineal descent was 4.4+/-1 cm (normal < 4 cm) by scintigraphy. Scintigraphic evacuation, rectoanal angle change during defecation, and perineal descent were abnormal in 23%, 57%, and 78% of the patients, respectively. Associated features included female gender (96%), multiparity with vaginal delivery (55%), hysterectomy or cystocele/rectocele repair (74%). On follow-up, 64% responded; 17 of these 25 responders underwent pelvic floor retraining. At 2-yr median follow-up (range, 1-6 yr), 12 still experienced constipation or excessive straining; their perineal descent was greater than in patients who responded to retraining (p = 0.005). CONCLUSIONS: Descending perineum syndrome is identifiable by clinical history and examination, and the most prevalent abnormality on testing is perineal descent > 4 cm; rectal balloon expulsion is an insensitive screening test for descending perineum syndrome. Pelvic floor retraining is a suboptimal treatment for this chronic disorder of rectal evacuation; the extent of perineal descent appears to be a useful predictor of response to retraining.

Faecal incontinence with transitory absence of anal contraction in two sexually or physically abused women.

OBJECTIVE: To report two cases of faecal incontinence caused by transitory absence of anal voluntary contraction without anal anomalies. PATIENTS: Two women referred to our gastroenterology department with faecal incontinence. One patient had been sexually abused by her father; the other had been physically abused by her husband. RESULTS: Clinical and manometric anal contraction was absent despite normal anal endosonography and normal electrophysiological perineal study. Anal contraction was completely normalized after biofeedback, and the patients recovered from the faecal incontinence. CONCLUSION: Transitory absence of anal contraction is very uncommon as the origin of faecal incontinence. It was observed in two abused women.

[Chronic idiopathic constipation in adults. Pathogenesis and treatment]. / Constipation idiopathique chronique de l'adulte. Pathogénie et traitement.

The purpose of this review article is to outline the main factors underlying adult chronic idiopathic constipation (colic substrates, bacterial fermentation, colic peristalsis, perineal anomalies and psychological factors) as well as readily available exploratory methods (colic transit time, anorectal manometry). A review is made of the various therapeutic possibilities, taking into account hygienico-dietetic and pharmacological treatments (mono- or multifactorial laxatives), biofeedback and psychological approaches. The main cases seen in clinical practice are described.

Mechanisms of constipation in older persons and effects of fiber compared with placebo.

OBJECTIVE: To investigate the mechanisms of constipation and the effect of fiber supplementation on physiology, mechanisms, stool parameters, and colonic transit times in a group of constipated older patients. DESIGN: Single-blind, randomized, placebo-controlled fiber intervention with crossover. SETTING: A university-based outpatient center. PATIENTS: Ten community-living older men and women, healthy except for chronic constipation. INTERVENTIONS: Patients were given either 24 g psyllium fiber or placebo fiber daily for 1 month, then crossed over to the other arm for an additional month. Structured testing, including total gut transit time and rectal and colonic manometry, was performed at the end of each intervention month. Patients recorded stool frequency, consistency, and weights daily. RESULTS: The predominant mechanism for constipation in these patients was outlet delay caused by pelvic dyssynergia. Fiber decreased total gut transit time from 53.9 hours (placebo condition) to 30.0 hours (P < .05). Stool weights and consistency were not significantly improved by fiber, though there was a trend toward an increase in stool frequency (1.3 vs 0.8 bowel movements per day.) Pelvic floor dyssynergia was not remedied by fiber, even when constipation was clinically improved. CONCLUSIONS: Fiber supplementation appeared to benefit constipated older patients clinically, and it improved colonic transit time, but it did not rectify the most frequent underlying abnormality, pelvic floor dyssynergia.

Ambulatory bio-feedback for stress incontinence exercise regimes: a novel development of the perineometer.

Stress incontinence is a debilitating condition affecting a large proportion of the female population. Pelvic floor exercising with the aid of bio-feedback is well established as an effective treatment regime. However, current monitoring devices are restrictive in the way they may be employed in community-based therapy. A prototype unit is described, which is both compact and accurate and suitable for ambulatory monitoring of vaginal pressure. This device is suitable for self-help domiciliary regimes and may also be used as an accurate yardstick to judge individual response to therapy. Conceptual changes in health-care provision are leading to greater emphasis on community-centred care for non-acute conditions such as stress incontinence. Development of more appropriate scientific and technological support is likely to have a fundamental role in the success of such schemes.
