BACKGROUND: Impaired gastric emptying is common in critically ill patients. Intestinal dysmotility, a major cause of feed intolerance, may foster infectious complications due to mucosal barrier disruption. However, little is known about gut-directed immune activation, intestinal barrier function and its association with impaired gastric emptying in critically ill patients at ICU admission. METHODS: We conducted a prospective observational study at two tertiary care medical ICUs...

BACKGROUND: The aetiology and origin of gastrointestinal symptoms in Parkinson's disease (PD) remains poorly understood. Gastroparesis, small bowel transit delay and bacterial overgrowth may, individually or collectively, play a role. AIMS: In patients with PD and functional gastrointestinal symptoms, we aimed to determine the utility of the wireless motility capsule and lactulose breath tests in further defining their symptoms' aetiology. METHODS: In this retrospective cohort study, consecutive patients with PD and functional gastrointestinal symptoms underwent clinical assessment, as well as wireless motility capsule and lactulose breath testing using standard protocols...

Functional gastrointestinal disorders (FGIDs) negatively affect children's quality of life and health care costs. It has been proposed that alteration of gut serotonin leads to gastrointestinal dysmotility, visceral hypersensitivity, altered gastrointestinal secretions, and brain-gut dysfunction. Cyproheptadine, a serotonin antagonist, has been shown to be a potentially effective and safe treatment option in children who meet the clinical criteria for FGIDs. Well-designed multicenter trials with long-term follow-up are needed to further investigate its efficacy...

AIM: To assess reference values in the literature for esophageal distensibility and cross-sectional area in healthy and diseased subjects measured by the functional lumen imaging probe (FLIP). METHODS: Systematic search and review of articles in Medline and Embase pertaining to the use of FLIP in the esophagus was conducted in accordance with the PRISMA guidelines. Cross-sectional area and distensibility at the esophagogastric junction (EGJ) were abstracted for normal subjects, achalasia, and gastroesophageal reflux disease (GERD) patients, stratified by balloon length and volume of inflation...

BACKGROUND: Gastrointestinal adverse effects occurring during cancer chemotherapy are well known and feared; those persisting once treatment has finished are relatively unknown. We characterized the alterations occurring in the rat small intestine, after repeated treatment with cisplatin. METHODS: Male Wistar rats received saline or cisplatin (2 mg kg(-1)  week(-1) , for 5 weeks, ip). Gastric motor function was studied non-invasively throughout treatment (W1-W5) and 1 week after treatment finalization (W6)...

Gastroesophageal reflux disease (GERD) is a condition, which develops when the reflux of stomach contents causes troublesome symptoms and/or complications. In patients with alarm symptoms or signs or in those refractory to antiacid therapy, it is indicated to perform instrumental tests to correctly diagnose GERD presence. Esophageal manometry is currently considered the gold standard test for the diagnosis of esophageal dysmotility. However, it has shown limited capability in diagnosing GERD. With the advent of high resolution manometry (HRM), more accurate evaluations of esophageal motility are now possible...

Mariano A Menezes, Fernando A M Herbella
Gastroesophageal reflux disease pathophysiology is multifactorial and linked to a misbalance between the aggressiveness of the refluxate into the esophagus or adjacent organs and the failure of protective mechanisms associate or not to a defective valvular mechanism at the level of the esophagogastric junction incapable of dealing with a transdiaphragmatic pressure gradient. Antireflux mechanisms include the lower esophageal sphincter and abdominal esophagus, the diaphragm, the angle of His, the Gubaroff valve, and the phrenoesophageal membrane...

Gastrointestinal (GI) hormonal peptides play a role in the development of gastrointestinal malignancies, and their abnormal levels may contribute to dysmotility. The aim of this study was to analyze plasma concentrations of enterohormones (motilin, ghrelin, gastrin and pancreatic polypeptide) and to verify if their abnormal levels may contribute to the severity of dyspeptic symptoms in colorectal cancer patients. The study included 60 patients with colorectal malignancies (22 men and 38 women), among them 30 individuals with colon cancers (group A) and 30 subjects with rectal tumors (group B)...

INTRODUCTION Fundoplication for laryngopharyngeal disease with oesophageal dysmotility has led to mixed outcomes. In the presence of preoperative dysphagia and oesophageal dysmotility, this procedure has engendered concern in certain regards. METHODS This paper describes a consecutive series of laryngopharyngeal reflux (LPR) patients with a high frequency of dysmotility. Patients were selected for surgery with 24-hour dual channel pH monitoring, oesophageal manometry and standardised reflux scintigraphy. RESULTS Following careful patient selection, 33 patients underwent fundoplication by laparoscopy...

BACKGROUND: Colonic volvulus is rare in children and associated with colonic dysmotility. Diagnosis of colonic volvulus on radiographs in these patients can be challenging. The purpose of the study was to identify the accuracy of abdominal radiographs and findings suggestive of colonic volvulus. MATERIALS AND METHODS: A retrospective (2003- 2014) study of all children with colonic volvulus proven surgically or endoscopically reviewed their medical charts for underlying disease and clinical presentation as well as their original radiograph reports...

Patients receiving hemodialysis also manifest gastrointestinal symptoms, such as constipation, caused by restriction of water intake and the loss of body water balance. Because dietary carnitine deficiency is considered to cause smooth muscle dysmotility of the gastrointestinal tract similarly to that in skeletal muscles, carnitine deficiency in hemodialysis patients may be one cause of gastrointestinal discomfort and dysfunctions. We performed a multicenter nonrandomized single-arm prospective clinical trial...

REVIEW
Sven Wehner, Daniel Robert Engel
Macrophages reside in a dense cellular network in the intestinal muscularis externa, and there is emerging evidence that the functionality of these cells determines the local microenvironment. Inflammatory responses during intestinal diseases change the homeostatic functionality of these cells causing inflammation and intestinal dysmotility. Such disturbances are not only induced by a change in the cellular composition in the intestinal muscularis but also by an altered crosstalk with the peripheral and central nervous system...

BACKGROUND AND OBJECTIVE: Cilia-driven mucociliary clearance is an important self-defense mechanism of great clinical importance in pulmonary research. Conventional light microscopy possesses the capability to visualize individual cilia and its beating pattern but lacks the throughput to assess the global ciliary activities and flow dynamics. Optical coherence tomography (OCT), which provides depth-resolved cross-sectional images, was recently introduced to this area. MATERIALS AND METHODS: Fourteen de-identified human tracheobronchial tissues are directly imaged by two OCT systems: one system centered at 1,300 nm with 6...

PURPOSE OF REVIEW: Impedance planimetry measures tissue wall distensibility as a function of pressure and cross-sectional area. Recent interest in this technique's relevance to the gastrointestinal tract has been accelerated by the availability of the functional lumen imaging probe, a catheter-based system that dynamically quantitates these biomechanical properties. Herein, we review the device's particular utility in the setting of esophageal pathology, including processes affecting the esophageal body as well as the upper and lower esophageal sphincters...

Background: In different models of paralytic ileus, cannabinoid receptors are overexpressed and endogenous cannabinoids are massively released, contributing to gastrointestinal dysmotility. The antitumoral drug vincristine depresses gastrointestinal motility and a similar mechanism could participate in this effect. Therefore, our aim was to determine, using CB1 and CB2 antagonists, whether an increased endocannabinoid tone is involved in vincristine-induced gastrointestinal ileus. Methods: First, we confirmed the effects of vincristine on the gut mucosa, by conventional histological techniques, and characterized its effects on motility, by radiographic means...

BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) is increasingly being applied to treat obesity. LSG includes excision of the normal gastric pacemaker, which could induce electrical dysrhythmias impacting on post-operative symptoms and recovery, but these implications have not been adequately investigated. This study aimed to define the effects of LSG on gastric slow-wave pacemaking using laparoscopic high-resolution (HR) electrical mapping. METHODS: Laparoscopic HR mapping was performed before and after LSG using flexible printed circuit arrays (64-96 electrodes; 8-12 cm(2); n = 8 patients) deployed through a 12 mm trocar and positioned on the gastric serosa...

A Fikree, Q Aziz, D Sifrim
BACKGROUND: The joint hypermobility syndrome (JHS) is a common non-inflammatory connective tissue disorder which frequently co-exists with postural tachycardia syndrome (PoTS), a form of orthostatic intolerance. Gastrointestinal symptoms and dysmotility have been reported in PoTS. Dysphagia and reflux are common symptoms in JHS, yet no studies have examined the physiological mechanism for these, subdivided by PoTS status. METHODS: Thirty patients (28 female, ages: 18-62) with JHS and symptoms of reflux (n=28) ± dysphagia (n=25), underwent high-resolution manometry and 24 hour pH-impedance monitoring after questionnaire-based symptom assessment...

BACKGROUND: Celiac disease is a chronic, small intestinal, immune-mediated enteropathy caused by a permanent intolerance to dietary gluten in genetically predisposed individuals. Clinical studies have found that intestinal cholecystokinin secretion and gallbladder emptying in response to a fatty meal are impaired before celiac patients start the gluten-free diet (GFD). DESIGN: However, it was never really appreciated whether celiac disease is associated with gallstones because there were very few studies investigating the mechanism underlying the impact of celiac disease on the pathogenesis of gallstones...

BACKGROUND: Gastroesophageal reflux disease is thought to predispose to adverse lung allograft outcomes. However, little is known about the burden of gastroesophageal reflux (GER) and gastroparesis in pediatric patients. In this study we describe the burden of reflux and gastroparesis in children undergoing lung transplant, and evaluates their impact on allograft survival and rejection incidence. METHODS: This study is a retrospective analysis of pediatric lung transplant recipients who had combined pH and multichannel intraluminal impedance testing (pH-MII) and gastric-emptying scans (GES)...
