Gastric and sacral electrical stimulation for motility disorders-A clinical perspective.

Background: Electrical stimulation of the gut has been investigated in recent decades with a view to treating various gastro-intestinal motility disorders including, among others, gastric electrical stimulation to relieve nausea and vomiting associated with gastroparesis and sacral neuromodulation to treat fecal incontinence and/or constipation. Although their symptomatic efficacy has been ascertained by randomized controlled trials, their mechanisms of action are not fully understood.

Purpose: This review summarizes the past year's literature on the mechanisms of action of gut electrical stimulation therapies, including their impact on the gut-brain axis.

Alterations in gastrointestinal motility assessed by high-resolution antroduodenal manometry in patients with severe disorders of gut-brain interaction.

Data are limited regarding gastrointestinal motility disturbance in disorders of gut-brain interaction (DGBI). This study aimed to characterize antroduodenal motor alterations in patients with high-resolution antroduodenal manometry (HR-ADM). HR-ADM was performed in patients with severe DGBI and compared with healthy volunteers (HV).

Fecal Incontinence Subtype Assessment (FI-SA): Validation of a new tool to distinguish among subtypes of fecal incontinence.

Purpose: Three subtypes of fecal incontinence (FI) are described in the literature: urge, mixed and passive FI, but the relevance of this classification remains unknown. To our knowledge, no questionnaire has been validated in a general population of patients with FI to classify patients between the different subtypes of FI. The aim of the present study was to validate the Fecal Incontinence Subtype Assessment (FI-SA) questionnaire in a general population of patients with FI.

Intrarectal injections of botulinum toxin versus placebo for the treatment of urge faecal incontinence in adults (FI-Toxin): a double-blind, multicentre, randomised, controlled phase 3 study.

Background: Non-randomised studies assessing intrarectal botulinum toxin type A (BoNTA) injections for faecal incontinence are promising. We aimed to evaluate the efficacy of BoNTA for the treatment of faecal incontinence in a randomised study.

Methods: In this randomised, double-blind, placebo-controlled study, we included adult patients who had at least one urgency or faecal incontinence episode per week for at least 3 months and who had experienced a failure of conservative or surgical treatment from eight French specialist hospital units with the skills to manage patients with faecal incontinence.

Evaluation of the efficacy of sacral neuromodulation in the treatment of voiding dysfunction after endometriosis surgery.

Pelvic surgery for endometriosis is associated with a risk of bladder and digestive sequelae. Sacral neuromodulation (SNM) has been shown to be effective in the treatment of overactive bladder (OAB) and voiding dysfunction (VD). This study aimed to evaluate the efficacy of sacral neuromodulation (SNM) in treating voiding dysfunction (VD) following endometriosis surgery.

Physiological characterization of gastric emptying using high-resolution antropyloroduodenal manometry.

Delayed gastric emptying (GE) has been associated with antral and pyloric dysmotility. We aimed to characterize differences in the antral, duodenal, and pyloric motility profiles associated with delayed GE, using high-resolution antropyloroduodenal manometry (HR-ADM). Patients referred for HR-ADM for dyspeptic symptoms performed a concurrent GE breath test (NCT01519180 and NCT04918329).

Multiple sclerosis and bowel symptoms: Frequency and barriers to their management.

Background: The frequency of bowel symptoms (BSs) is still a matter for debate in multiple sclerosis (MS) patients. However, BSs have been shown to cause significant distress. Our study aimed to (i) investigate the frequency of BSs, particularly those that are not managed, (ii) identify potential predictors for help-seeking care for patients with BSs, and (iii) evaluate the ability of the Neurogenic Bowel Dysfunction (NBD) score to screen for BSs.

Impact of anesthetics on pyloric characteristics measured using the EndoFLIP® system in patients with gastroparesis.

Background: Pyloric distensibility has been reported as a predictive measure in gastroparesis. Measures can be obtained either during endoscopy under anesthesia or in unsedated patients. However, the impact of anesthetic drugs on the results of pyloric characteristics remains unknown.

Interferential therapy for chronic constipation in adults: The CON-COUR randomizedcontrolled trial.

Background: Chronic constipation (CC) is a frequent condition, and the first-line treatment includes dietary rules, the use of laxatives, and biofeedback for evacuation disorders. However, almost half of the patients are dissatisfied with their current treatment. We report the first double-blind randomized multicenter trial assessing the effectiveness of transabdominal electrical stimulation by interferential therapy (IFT) in the treatment of CC in adults.

Involvement of acid sensing ion channel (ASIC)-3 in an acute urinary bladder-colon cross sensitization model in rodent.

Introduction: Irritable bowel syndrome and bladder pain syndrome are both characterized by pain in response to organ distension. Epidemiologic studies showed that these two syndromes are often overlapped. Such overlap may be due to sharing of common extrinsic innervations between the colorectum and the urinary bladder, where cross-sensitization of the urinary bladder and the colon would occur in response to mechanical distension of either organ.

Transanal irrigation is a better choice for bowel dysfunction in adults with Spina bifida: A randomised controlled trial.

Aim: To compare transanal irrigation with conservative bowel management for the treatment of bowel dysfunction in Spina bifida (SB) patients.

Methods: Patients with SB and bowel dysfunction were randomly assigned to receive either transanal irrigation or conservative bowel management. The effectiveness of the treatment was defined as a decrease of 4 points in the neurogenic bowel dysfunction (NBD) score at week 10.

Bladder-colon chronic cross-sensitization involves neuro-glial pathways in male mice.

Background: Irritable bowel syndrome and bladder pain syndrome often overlap and are both characterized by visceral hypersensitivity. Since pelvic organs share common sensory pathways, it is likely that those syndromes involve a cross-sensitization of the bladder and the colon. The precise pathophysiology remains poorly understood.

Relationship between anal functional lumen imaging probe (EndoFLIP®) results and the clinical presentation of faecal incontinence.

Aim: Faecal incontinence (FI) subtypes (urge, passive, mixed) are linked to the physiopathological mechanism of FI. Previous studies have failed to demonstrate a consistent relationship between FI subtype and anal sphincter dysfunction. Our aim was to evaluate the relationship between anal sphincter function, assessed using the new EndoFLIP® technology, and FI subtype.

Overlaps with bladder pain syndrome and irritable bowel syndrome are associated with higher symptom burden and reduced quality of life in functional dyspepsia.

Background: Functional dyspepsia and bladder pain syndrome are well-known to overlap with irritable bowel syndrome. Whether functional dyspepsia overlaps with bladder pain syndrome remains unknown. Our aim was to evaluate the presence of bladder pain syndrome in functional dyspepsia patients and its impact.

Fecal incontinence subtype assessment (FI-SA): A new tool to distinguish among subtypes of fecal incontinence in a neurogenic population.

Introduction: Two subtypes of fecal incontinence (FI) are defined in the literature (urge and passive FI). The pertinence of this classification is unknown due to conflicting findings and heterogeneity of definitions. However, no questionnaire is available to clearly classify patients among subtypes.

Sleep Quality and Insomnia Are Associated With Quality of Life in Functional Dyspepsia.

Background: Sleep disturbances are common in patients with functional dyspepsia. Our aim was to assess the relationship between subjective sleep and quality of life and to identify factors associated with impaired sleep in functional dyspepsia.

Methods: One thousand two hundred and twenty patients referred for functional gastrointestinal disorders at a single tertiary care center between end 2017 and June 2019 were studied using a self-administered questionnaire.

Delayed gastric emptying as an independent predictor of mortality in gastroparesis.

Background: Whether gastroparesis is associated with a shortened life expectancy remains uncertain as no systematic study has evaluated the impact of gastroparesis on mortality, based on gastric emptying (GE) tests.

Aim: This study aimed to assess whether delayed GE was predictive of mortality.

Methods: GE was measured using a 13C-octanoic acid breath test in 1563 consecutive patients.

Is sacral nerve modulation reprogramming effective after permanent implantation for faecal incontinence?

Aim: Sacral nerve modulation (SNM) is recommended as a first-line surgical therapy for patients with faecal incontinence (FI). During patient follow-up, it is recommended that stimulation settings be reprogrammed to optimize patient outcomes. The aim of the present study was to evaluate the efficacy of stimulator reprogramming in patients with an implanted SNM device to treat FI.

Disorders of anorectal motility: Functional defecation disorders and fecal incontinence.

Functional defecation disorders (FDDs) and fecal incontinence (FI) are common anorectal disorders often distressing and significantly add to the healthcare burden. They present with multiple, overlapping symptoms that can often obscure the underlying pathophysiology and can pose significant management dilemmas. A detailed history, stool diaries and visual scales of stool form, a careful digital rectal examination are needed to guide anorectal physiology tests.

Recommendations on the management of pudendal nerve entrapment syndrome: A formalised expert consensus.

Background: Since the development and publication of diagnostic criteria for pudendal nerve entrapment (PNE) syndrome in 2008, no comprehensive work has been published on the clinical knowledge in the management of this condition. The aim of this work was to develop recommendations on the diagnosis and the management of PNE.

Methods: The methodology of this study was based on French High Authority for Health Method for the development of good practice and the literature review was based on the PRISMA method.
