Abstract
Common disorders of the gastrointestinal (GI) tract, such as gastroesophageal reflux/disease (GER/D) and constipation, are frequent causes for seeking medical support in infants. Diagnostic workup must ensure that diagnosed diseases are responsible for such complaints, thus enabling appropriate therapy. In this context assessment consists of clinical examination, functional tests, and imaging, which should be done in a staged manner. Close cooperation between clinicians and clinical radiologists enables optimal diagnostics, thus forming the basis for appropriate therapy.

[PMID: 37680050 DOI: 10.1111/aor.14632] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2023] [Revised: 08/01/2023] [Accepted: 08/09/2023] [Indexed: 09/09/2023]
Abstract
BACKGROUND Artificial anal sphincter is an implantable medical device for treating fecal incontinence. Reasonable simulation facilitates the advancement of research and reduces experiments on biological tissue. However, the device's clamping motion and sensor interaction with the intestine in the simulation still require further exploration. This article presents a simulation of the artificial anal sphincter's clamping and sensing and its interaction with the intestinal environment using the Simulation Open Framework Architecture (SOFA). METHODS Firstly, the proposed simulation algorithm and its principles in SOFA are analyzed. Secondly, the clamping motion and sensor system of the artificial anal sphincter are simulated. Thirdly, a finite element model of intestine is established based on the properties of intestinal soft tissue. Finally, the in vitro experiments are performed. RESULTS The simulation results indicate that the sensor system of the artificial anal sphincter has good sensing performance during the clamping motion and fecal accumulation process. Experiments have shown that optimal sensory capabilities can be achieved as the posture of the artificial anal sphincter with a roll angle between 20° and 40°. The comparison demonstrates a mean absolute error of 10%-20% between simulation and in vitro experimental results for sensor forces, which verifies the effectiveness of the simulation. CONCLUSION The proposed novel simulation achieves a more comprehensive interaction between the artificial anal sphincter motion and intestinal environment. This study may provide more effective simulation data for guidance in improving the performance of sensor perception of artificial anal sphincter for further research.

The Water-Holding Procedure for Ensuring Postoperative Continence Prior Restoring Intestinal Continuity. J Gastrointest Surg 2020; 24:411-417.

Abstract
BACKGROUND A defunctioning stoma can become necessary in a relevant number of patients undergoing gastrointestinal surgery. As a matter of course, patients seek an early closure of the stoma. However, preoperative management of these patients varies and the prediction of continence after stoma removal can become challenging. Patients might be fully continent despite low manometric pressures and vice versa. An easy and reliable way to predict continence after stoma reversal would improve patients' management and outcome. Although frequently performed in various surgical centers in Germany, there is no published data on the water-holding test. Hence, this is the first study evaluating the role of the test in clinical practice. METHOD We performed a prospective pilot study to evaluate the role of anorectal manometry and the water-holding procedure as a predictor of postoperative continence prior to stoma reversal. Inclusion criteria were a successfully passed water-holding test, any type of fecal diversion and the possibility of restoring intestinal continuity. Preoperative low manometric pressure levels were not an exclusion criteria for stoma reversal. Fifty-two patients with ostomy were consecutively enrolled in this study between October 2013 and February 2016. Anorectal manometry was performed in all patients prior to stoma reversal. After stoma removal, patients were followed-up for 6 months. Postoperative incontinence was determined using the Wexner incontinence score. RESULTS A total of 52 patients (38 males, 14 females) were included at an average age of 59 (range 33-83) years. Most frequent indications for intestinal diversion were rectal cancer surgery, IBD-related surgery, or surgery for diverticular disease. Low anterior rectal resection was performed in 17 patients (32.7%), followed by a proctocolectomy in 9 (17.3%), colectomy in 9 (17.3%), and recto-sigmoid resection in 7 patients (13.5%). Median time from stoma creation to reversal was 206 days (range 48-871 days). All patients had successfully passed the standardized water-holding test. At the same time, the majority of patients had low preoperative manometric pressure values and would normally not have been reversed at that point. The median postoperative Wexner incontinence score was at 1.5 (range 0-20), 0.5 (range 0-14), and 0 (range 0-11) at 14, 60, and 180 days after stoma reversal. Low preoperative manometric squeeze and/or resting pressure levels were not associated with a higher postoperative incontinence score at 14, 60, or 180 days after stoma reversal. CONCLUSION A standardized water-holding test can function as an easy and reliable method before stoma reversal to predict sufficient postoperative fecal continence. In case of a sufficient water-holding test despite low manometric pressure levels, the risk for postoperative anal incontinence seems to be low. Preoperative manometric pressure levels do not appear to predict postoperative continence.

Abstract
Functional anorectal disorders such as faecal incontinence (FI), functional anorectal pain, and functional defecation disorders (FDD) are highly prevalent and represent a high socioeconomic burden. Several tests of anorectal function exist in this setting; however, high-resolution anorectal manometry (HR-ARM) is a new tool that depicts pressure all along the anal canal and can assess rectoanal coordination. HR-ARM is used in the diagnosis of FI and especially FDD although data in health is still sparse, and pressure phenomena seen during simulated defecation, such as dyssynergia, are highly prevalent in health.

Abstract
A considerable body of research has recently emerged around nonmotor symptoms in Parkinson's disease (PD) and their substantial impact on patients' well-being. A prominent example is constipation which occurs in up to two thirds of all PD-patients thereby effecting psychological and social distress and consequently reducing quality of life. Despite the significant clinical relevance of constipation, unfortunately little knowledge exists on effective treatments. Therefore this systematic review aims at providing a synopsis on clinical effects and safety of available treatment options for constipation in PD. For this purpose, three electronic databases (MEDLINE, EMBASE, PsycINFO) were searched for experimental and quasi-experimental studies investigating the efficacy/effectiveness of interventions in the management of PD-associated constipation. Besides, adverse events were analyzed as secondary outcome. In total, 18 publications were identified involving 15 different interventions, of which none can be attributed sufficient evidence to derive strong recommendations. Nevertheless, some evidence indicates that dietetic interventions with probiotics and prebiotics may reduce symptom burden while providing a very favorable side-effects profile. Furthermore, the use of lubiprostone, macrogol and in the specific case of isolated or prominent outlet obstruction constipation injections of botulinum neurotoxin A into the puborectal muscles may as well be moderately supported. In summary, too little attention has been paid to treatment options for constipation in PD leaving abundant room for further research addressing this topic.

Abstract
BACKGROUND Ano-rectal manometry (ARM) is the most commonly performed investigation for assessment of anorectal dysfunction. Its use is supported by expert consensus documents and international guidelines. Variation in technology, data acquisition, and analysis affect results and clinical interpretation. This study examined variation in ARM between institutions to establish the status of current practice. METHODS A 50-item web-based questionnaire assessing analysis and interpretation of ARM was distributed by the International Anorectal Physiology Working Group via societies representing practitioners that perform ARM. Study methodology and performance characteristics between institutions were compared. KEY RESULTS One hundred and seven complete responses were included from 30 countries. Seventy-nine (74%) institutions performed at least two studies per week. Forty-nine centers (47%) applied conventional ARM (≤8 pressure sensors) and 57 (53%) high-resolution ARM (HR-ARM). Specialist centers were most likely to use HR-ARM compared to regional hospitals and office-based practice (63% vs 37%). Most conventional ARM systems used water-perfused technology (34/49); solid-state hardware was more frequently used in centers performing HR-ARM (44/57). All centers evaluated rest and squeeze. There was marked variation in the methods used to report results of maneuvers. No two centers had identical protocols for patient preparation, setup, study, and data interpretation, and no center fully complied with published guidelines. CONCLUSIONS & INFERENCES There is significant discrepancy in methods for data acquisition, analysis, and interpretation of ARM. This is likely to impact clinical interpretation, transfer of data between institutions, and research collaboration. There is a need for expert international co-operation to standardize ARM.

Abstract
BACKGROUND The reasons for fecal incontinence after surgery for Hirschsprung disease (HD) remain unclear. The aim of this study was to examine the anal sphincters by anal endosonography and manometry after transanal endorectal pull-through, with or without laparotomy or laparoscopy, in HD patients. Furthermore, we aimed to correlate these findings to bowel function. PATIENTS AND METHODS Fifty-two HD patients were followed after endorectal pull-through. Anal endosonography and manometry were performed without sedation at the age of 3 to 16 years. RESULTS Endosonographic internal anal sphincter (IAS) defects were found in 24/50 patients, more frequently after transanal than transabdominal procedures (69 vs. 19%, p=0.001). In a multiple variable logistic regression model, operative approach was the only significant predictor for IAS defects. Anal resting pressure (median 40mm Hg, range 15-120) was not correlated to presence of IAS defects. Daily fecal incontinence occurred more often in patients with IAS defects (54 vs. 25%, p=0.03). CONCLUSIONS Postoperative IAS defects were frequently detected and were associated with daily fecal incontinence. IAS defects occurred more often after solely transanal procedures. We propose that these surgical approaches are compared in a randomized controlled trial before solely transanal endorectal pull-through is performed as a routine procedure.

Abstract
PURPOSE Anorectal manometry provides objective information about anorectal function, but its results depend on the examiner's skill, the type of equipment, and subject characteristics like age or gender. This single institution, prospective study was performed to investigate the effect of gender and age on the results of anorectal manometry. METHODS All included subjects completed a questionnaire to assess their bowel function. The survey included 13 validated questions (eight on constipation and five on incontinence) and was used to exclude subjects with pathological constipation or incontinence. Subjects with normal bowel function underwent anorectal manometry to measure anal sphincter length (ASL), maximum resting pressure (MRP), and maximum squeeze pressure (MSP), and the results were compared by gender and age. RESULTS The mean age of the 154 participants (94 male and 60 female) was 59.1 years. ASL was greater in men (4.23 vs. 3.85 cm, p < 0.001). MRP was not significantly different according to gender (p = 0.93), but MSP was higher in men (190.18 vs. 116.49 mmHg, p < 0.001). ASL did not correlate with age (p = 0.707). MRP was inversely related to age in both men (R (2) = 0.152, p < 0.001) and women (R (2) = 0.282, p < 0.001), and MSP only in women (R (2) = 0.210, p < 0.001). CONCLUSIONS Anorectal manometric parameters are influenced by gender and age. This should be taken into consideration when interpreting manometric readings in a clinical setting.

Abstract
BACKGROUND Measurements of anorectal function using high-resolution anorectal manometry (HR-ARM) and rectal barostat technology provide more reliable results than standard ARM with an elastic balloon; however, HR-ARM results have not been compared to ARM and standard barostat protocols are impractical in routine clinical practice. The aim of this study was to validate HR-ARM against standard ARM and standard barostat against a novel Rapid Barostat Bag (RBB) measurement and elastic balloon measurements of rectal function. METHODS Twenty-six healthy volunteers (15 female, 11 male, 19-52 years) were studied. Measurements of anal function and simulated defecation were compared for 12-sensor HR-ARM and 6-sensor standard ARM using line plots from the same recording. Rectal capacity, compliance, and sensation (volume threshold) were measured by elastic balloon, standard barostat, and RBB methods using stepwise inflation of a 700-mL polyethylene bag to 40 mmHg distension by electronic barostat and handheld syringe monitored by sphygmo-manometer, respectively. Results are reported as mean ± SD. Bland-Altman plots and correlation coefficients (r) for measurements were calculated. KEY RESULTS There was excellent agreement between HR- and standard ARM measurements (r > 0.86, <25 mmHg difference) and between standard barostat and RBB measurements of rectal capacity (r = 0.97, <25 mL difference). Correlation coefficients of threshold volumes for initial perception, urgency and discomfort were 0.37, 0.71, and 0.95, respectively. No significant correlation was present with elastic balloon measurements. Time to complete studies was shorter for HR-ARM than standard ARM and for RBB than standard barostat in historical controls. CONCLUSIONS & INFERENCES HR-ARM with RBB measurements of anorectal function provides quick and reasonably accurate measurements of continence function suitable for use in routine clinical practice (ClinicalTrial.gov NCT01456442).

Abstract
BACKGROUND Guidelines recommend instruction and motivation during anorectal manometry; however, its impact on findings has not been reported. This study assessed the effects of standard versus enhanced instruction and verbal feedback on the results of anorectal manometry. METHODS High-resolution manometry was performed by a solid-state catheter with 10 circumferential sensors at 6 mm separation across the anal canal and two rectal sensors. Measurements were acquired first with standard instruction and then with enhanced instruction and verbal feedback. On both occasions, squeeze pressure and duration during three voluntary contractions and intra-rectal pressure and recto-anal pressure gradient (RAPG) during three attempts at simulated defecation were assessed. KEY RESULTS A total of 70 consecutive patients (54 female; age 25-82 years) referred for investigation of fecal incontinence (n = 31), constipation, and related disorders of defecation (n = 39) were studied. Enhanced instruction and verbal feedback increased maximum squeeze pressure (Δ10 ± 28.5 mmHg; P < 0.0038) and duration of contraction (Δ3 ± 4 s; P < 0.0001). During simulated defecation, it increased intra-rectal pressure (Δ12 ± 14 mmHg; P < 0.003) and RAPG (Δ11 ± 20 mmHg; P < 0.0001). Using standard diagnostic criteria, the intervention changed manometric findings from locally validated 'pathologic' to 'normal' values in 14/31 patients with incontinence and 12/39 with disorders of defecation. CONCLUSIONS & INFERENCES Enhanced instruction and verbal feedback significantly improved voluntary anorectal functions and resulted in a clinically relevant change of manometric diagnosis in some patients. Effective explanation of procedures and motivation during manometry is required to ensure consistent results and to provide an accurate representation of patient ability to retain continence and evacuate stool.

Abstract
The majority of proctological diseases can be defined by a structured evaluation of the symptoms and a physical examination. Magnetic resonance imaging (MRI) and anal endosonography can detect complex anal fistulas with a high accuracy but MRI should be preferred because of its objective visualization. Functional anorectal disorders are multifactorial and show morphological and functional irregularities in different compartments of the pelvic floor which is why MR defecography is now one of the most important methods in diagnostic algorithms. Interpreting the results of anal endosonography, anal manometry and neurophysiological testing is highly demanding because of large interindividual variability. Scores are used for objective measurement of symptom severity and quality of life. In clinical practice, well validated scores evaluated in large patient groups with predetermined circumstances are needed. Bringing together morphological results with scores based on subjective perception is required to optimize diagnostics and therapy evaluation in proctology.

Abstract
PURPOSE The aims of this study were to obtain normative values in resting/squeeze pressure and surface electromyography (s-EMG) in anorectal manometry using microtip technology and to determine the relationship between objective measurable values, gender and age in a cohort with no anorectal disorders. METHODS One hundred seventy-two white central European subjects (106 males/66 females) were recruited prior to left colonic or upper rectal surgery and studied by anorectal rapid pull-through manometry with a microtip transducer system and endoanal s-EMG using a bipolar plug electrode. s-EMG patterns were determined as plateau, peak and decrease by a blinded co-investigator. Objective measurable sphincter pressures and s-EMG values were correlated with gender, age and s-EMG patterns. RESULTS Squeeze pressure, voluntary pressure as well as s-EMG amplitude and its area under the curve were significantly lower in women compared to men (p < 0.001 each), whereas resting pressure showed no gender differences. s-EMG patterns were strongly influenced by gender. Male patients showed significantly more plateau pattern whereas peak pattern was significantly more often in women. In both genders, the peak pattern was associated with significant higher squeeze pressures. In all measurements, we found considerable inter-individual variations being higher in elder patients. There was no manometric parameter correlating with age. CONCLUSIONS Gender is the strongest factor influencing objective measurable manometric data for healthy men and women. There are significant gender differences concerning squeeze patterns. All manometric values should be interpreted in the context of gender and of methodology used. Large prospective cohort studies matched for gender are necessary to clarify the effect of ageing on anal sphincter strength.

Abstract
Motility and functional disorders of the small intestine, the colon and the anorectum can induce or contribute to symptoms such as diarrhoea, constipation and abdominal pain and may impair nutrient absorption in severe cases. Acute affections of intestinal functions e.g. during gastrointestinal infections usually need no functional diagnostics but resolve spontaneously or with adequate therapy of the underlying disease. By contrast, chronic disturbances of small intestinal, colonic and anorectal motility and/or sensitivity are subject to gastrointestinal function tests. The role of these tests for diagnosis and therapeutic handling of severe intestinal dysmotility/chronic intestinal pseudo-obstruction, severe constipation, diarrhoea, fecal incontinence and irritable bowel syndrome will be discussed in this review that mainly focuses on adults.

Abstract
Diagnostics and therapy of anorectal disorders are still questions of surgery. Exact knowledge of functional anatomy and precise clinical examination constitute the basis for the resulting therapeutic strategies. Three-dimensional endosonography and technical advances in flexible endoscopy using high-resolution chromoendoscopy and narrow-band imaging enable exact staging and diagnosis, even of malignancies in earliest stages. Furthermore new in-vivo staining methods combined with high-resolution imaging facilitate the discrimination of inflammatory and neoplastic lesions, which often lead to diagnostic difficulties in chronic inflammatory bowel disease. Developments in neurologic testing, including surface electromyography and sacral nerve stimulation, complement the diagnostic armamentarium.
