Feasibility and repeatability of ultrasound-guided surface electroenterography to measure colonic slow wave motility in healthy adults. BMC Gastroenterol 2024; 24:114. [PMID: 38500056 PMCID: PMC10949649 DOI: 10.1186/s12876-024-03196-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/25/2023] [Accepted: 03/05/2024] [Indexed: 03/20/2024] Open
Abstract
Surface electroenterography is a potential non-invasive alternative to current diagnostics of colonic motility disorders. However, electrode positioning in electroenterography is often based on general anatomy and may lack generalizability. Furthermore, the repeatability of electroenterography measurements is unknown. This study aimed to evaluate ultrasound-guided electrode positioning for electroenterography measurements and to determine the repeatability of those measurements. In ten healthy adults, two electroenterography procedures were performed, consisting of fasting, ultrasound-guided electrode localization and two 20-minute electroenterography recordings separated by a meal. The dominant frequency, the mean power density (magnitude of colonic motility) and the power percent difference (relative pre- to postprandial increase in magnitude) were determined. Repeatability was determined by Lin's concordance correlation coefficient. The results demonstrated that the dominant frequency did not differ between pre- and postprandial recordings and was 3 cpm, characteristic of colonic motility. The mean power density increased between the pre- and postprandial measurements, with an average difference of over 200%. The repeatability of both the dominant frequency and power density was poor to moderate, whereas the correlation coefficient of the power percent difference was poor. Concluding, ultrasound-guided surface electroenterography seems able to measure the gastrocolic reflex, but the dissatisfactory repeatability necessitates optimization of the measurement protocol.

Abstract
Fecal incontinence is the involuntary passage or the incapacity to control the release of fecal matter through the anus. It is a condition that significantly impairs quality of life in those that suffer from it, given that it affects body image, self-esteem, and interferes with everyday activities, in turn, favoring social isolation. There are no guidelines or consensus in Mexico on the topic, and so the Asociación Mexicana de Gastroenterología brought together a multidisciplinary group (gastroenterologists, neurogastroenterologists, and surgeons) to carry out the «Mexican consensus on fecal incontinence» and establish useful recommendations for the medical community. The present document presents the formulated recommendations in 35 statements. Fecal incontinence is known to be a frequent entity whose incidence increases as individuals age, but one that is under-recognized. The pathophysiology of incontinence is complex and multifactorial, and in most cases, there is more than one associated risk factor. Even though there is no diagnostic gold standard, the combination of tests that evaluate structure (endoanal ultrasound) and function (anorectal manometry) should be recommended in all cases. Treatment should also be multidisciplinary and general measures and drugs (lidamidine, loperamide) are recommended, as well as non-pharmacologic interventions, such as biofeedback therapy, in selected cases. Likewise, surgical treatment should be offered to selected patients and performed by experts.

Abstract
Despite the numerous available clinical investi-gation tests, the associated alteration of quality of life and the socio-economic cost, it remains difficult for physicians to identify the pathophysiological origins of defecation disorders and therefore to provide the appropriate clinical care. Based on standardized dynamic X-ray defecography, we developed a 2D patient-specific computational fluid dynamic model of rectal evacuation. X-ray defecography was carried out in a sitting position with a standardized paste whose yield stress matched that of soft human feces. The flow was simulated with lattice-Boltzmann methods for yield stress fluids and moving boundary conditions. The model was applied for a patient with a normal recto-anal function. We deduced from the flow field that the main flow resistance during the defecation was due to the extrusion of the paste through the anal canal. We calculated also from pressure and stress fields the spatio-temporal evolution of the wall normal stress. This latter highlighted a gradient from the proximal to the distal part of the rectum. We discussed how this new set of hydrodynamical and biome-chanical parameters could be interpreted to gain new insights on the physiology of defecation and to diagnose underlying evacuation disorders. Clinical relevance - If confirmed, our approach should allow clinicians to obtain other parameters from a classic clinical examination and thus better adapt the response of clinicians to the defecation disorders observed in patients.

Abstract
PURPOSE OF REVIEW Neurogastroenterology and motility is a rapidly evolving subspecialty that encompasses over 33% of gastroenterological disorders, and up to 50% of referrals to gastroenterology practice. It includes common problems such as dysphagia, gastroesophageal reflux disease, irritable bowel syndrome, chronic constipation, gastroparesis, functional dyspepsia, gas/bloating, small intestinal bacterial overgrowth, food intolerance and fecal incontinence Standard diagnostic tests such as endoscopy or imaging are normal in these conditions. To define the underlying mechanism(s)/etiology of these disorders, diagnostic motility tests are often required. These are best performed by well-trained personnel in a dedicated motility laboratory. Our purpose is to provide an up-to-date overview on how to organize and develop a motility laboratory based on our collective experiences in setting up such facilities in academia and community practice. RECENT FINDINGS A lack of knowledge, training and facilities for providing diagnostic motility tests has led to suboptimal patient care. A motility laboratory is the hub for diagnostic and therapeutic motility procedures. Common procedures include esophageal function tests such as esophageal manometry and pH monitoring, anorectal function tests suchlike anorectal manometry, neurophysiology and balloon expulsion, dysbiosis and food intolerance tests such as hydrogen/methane breath tests, and gastrointestinal transit assessment. These tests provide an accurate diagnosis and guide clinical management including use of medications, biofeedback therapy, neuromodulation, behavioral therapies, evidence-based dietary interventions and endoscopic or surgical procedures. Further, there have been recent developments in billing and coding of motility procedures and training requirements that are not well known. This review provides a stepwise approach on how to set-up a motility laboratory in the community or academic practice and includes the rationale, infrastructure, staffing needs, commonly performed motility tests and their clinical utility, billing and coding strategies, training needs and economic considerations for setting up this service.

Is evaluation by questionnaires sufficient to cover all aspects of bowel symptoms in rectal cancer patients after low anterior resection? Colorectal Dis 2022; 24:611-620. [PMID: 35040548 PMCID: PMC9306656 DOI: 10.1111/codi.16055] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/31/2021] [Revised: 01/05/2022] [Accepted: 01/08/2022] [Indexed: 01/01/2023]
Abstract
AIM The aim of the study was to investigate whether bowel symptoms related to low anterior resection for rectal cancer can be sufficiently well evaluated by the Low Anterior Resection Syndrome (LARS) questionnaire score or the ColoRectal Functional Outcome (COREFO) questionnaire compared with a stool diary. METHOD All patients underwent low anterior resection for rectal cancer. They were asked to fill out a stool diary, the LARS questionnaire and the COREFO questionnaire, at 1, 4, 6 and 12 months after low anterior resection or stoma closure. The main outcome measure was the amount of association (calculated by means of canonical correlation analysis) between items on anal incontinence for faeces, frequency of bowel movements, clustering of bowel movements, urgency and soiling. RESULTS Ninety-five patients were included. Items on anal incontinence for faeces and frequency of bowel movements were significantly correlated between the LARS questionnaire or the COREFO questionnaire, versus the stool diary, respectively. Items on soiling were significantly correlated between the COREFO questionnaire and the stool diary. CONCLUSION Although the LARS questionnaire and the COREFO questionnaire are reliable and valid for measuring low anterior resection syndrome after rectal cancer, our results show that there are no strong associations with the stool diary. Therefore, we can conclude that there is additional clinical information to be obtained from the stool diary. In order to evaluate all aspects of low anterior resection syndrome, we suggest the addition of a stool diary or a combination of different measurement methods during patient follow-up.

Abstract
Constipated patients are frequently referred to gastroenterologists for symptoms refractory to lifestyle modifications and laxatives. Dyssynergic defecation, the dyscoordination of rectoanal, abdominal, and pelvic floor muscles to facilitate defecation, is a major cause of refractory primary constipation. Understanding of the diagnosis, evaluation, and management of dyssynergic defecation and other evacuation disorders will allow providers to effectively manage these patients. This review focuses on the definition, pathophysiology, evaluation, and treatment of dyssynergic defecation and other evacuation disorders. Emerging treatments for these disorders include home biofeedback therapy for dyssynergic defecation and translumbosacral neuromodulation therapy for levator ani syndrome.

Abstract
The rectal motility function can reflect a person's rectal health status. To diagnose the rectal motility function after artificial anal sphincter implantation, this paper proposes a rectal function diagnosis model based on ensemble empirical mode decomposition-deep belief networks (EEMD-DBNs). Because of the rectal pressure signals that are unstable and subjected to noise interferences, an EEMD framework based on EMD, which can reduce the effect of signal modal mixing, is proposed. EMD and EEMD were used to decompose the analog signal, respectively, and it was found that EEMD can significantly reduce the effect of mode aliasing. During the rectal pressure signal decomposition experiment, by analyzing the intrinsic mode functions generated by the signals from normal people and diseased patients, the rectal signals at these two different conditions can be well distinguished. Additionally, the DBN was introduced to perform deep learning to extract the multi-dimensional features of rectal signals and then output the classification results via using the top-level classifier, which can overcome the difficulties in extracting the rectal signal features. The results showed that, following the principle of balancing the diagnosis accuracy and model running speed, the best diagnosis performance was achieved when three restricted Boltzmann machines and five layers of DBN model were set, with the diagnosis rate of 85%. The diagnostic model used in this study can distinguish the signals between normal and abnormal rectal functions with accurate performance, thus providing the technical support for the recovery of the rectal motility function of artificial anal sphincter implanters.
