What is the role of small bowel capsule endoscopy in established coeliac disease? Clin Res Hepatol Gastroenterol 2020; 44:753-761. [PMID: 31928969 DOI: 10.1016/j.clinre.2019.11.011] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/12/2019] [Revised: 11/22/2019] [Accepted: 11/25/2019] [Indexed: 02/04/2023]
Abstract
INTRODUCTION Patients with established coeliac disease (CD) can present with signs and symptoms requiring small bowel capsule endoscopy (SBCE) to assess for persistent disease beyond the duodenum and to rule out complications. There is paucity of data on extent of disease on SBCE in relation to histology, clinical and serological parameters. The aim of this study was to assess the relationship between symptoms, CD serology and Marsh classification of disease and extent of disease on SBCE in patients with established CD. METHODS Hundred patients with established CD and 200 controls underwent a SBCE. SBCEs were reviewed by expert reviewers. Extent of disease on SBCE, CD findings and small bowel transit were recorded. RESULTS Considering duodenal histology (D2; Marsh 3a or above) as the gold standard for diagnosing CD activity, the sensitivity of SBCE to delineate active disease was 87.2%. The specificity was 89.0%. Age at SBCE (P=0.006), albumin (P=0.004) and haemoglobin (P=0.0001), Marsh score of histology from the duodenal bulb (D1) (P=0.0001) and the second part of the duodenum (P=0.0001), refractory CD (P=0.007) on histology correlated with extent of affected small bowel (SB) mucosa on univariate analysis. On multiple regression analysis, albumin (P=0.036) and Marsh score of histology (D1) (P=0.019), vitamin B12 (P=0.001) and folate levels (P=0.008) were statistically significant. Extent of affected SB mucosa (11.0% vs 1.35%) was greater in patients with complications including those with refractory CD (P=0.008). CONCLUSIONS This is the first study showing correlation between extent of disease and severity of duodenal histology, markers of malabsorption such as folate levels and vitamin B12 and complications of CD.

The Influence of Small Intestinal Bacterial Overgrowth in Digestive and Extra-Intestinal Disorders. Int J Mol Sci 2020; 21:ijms21103531. [PMID: 32429454 PMCID: PMC7279035 DOI: 10.3390/ijms21103531] [Citation(s) in RCA: 18] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2020] [Revised: 05/13/2020] [Accepted: 05/15/2020] [Indexed: 02/07/2023] Open
Abstract
Small intestinal bacterial overgrowth (SIBO) is a condition hallmarked by an increase in the concentration of colonic-type bacteria in the small bowel. Watery diarrhea, bloating, abdominal pain and distension are the most common clinical manifestations. Additionally, malnutrition and vitamin (B12, D, A, and E) as well as minerals (iron and calcium) deficiency may be present. SIBO may mask or worsen the history of some diseases (celiac disease, irritable bowel disease), may be more common in some extra-intestinal disorders (scleroderma, obesity), or could even represent a pathogenetic link with some diseases, in which a perturbation of intestinal microbiota may be involved. On these bases, we performed a review to explore the multiple links between SIBO and digestive and extra-intestinal diseases.

Fasting Neurotensin Levels in Pediatric Celiac Disease Compared with a Control Cohort. Gastroenterol Res Pract 2020; 2020:1670479. [PMID: 32148474 PMCID: PMC7056991 DOI: 10.1155/2020/1670479] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/30/2019] [Revised: 01/04/2020] [Accepted: 02/06/2020] [Indexed: 11/17/2022] Open
Abstract
Background and Aims Neurotensin (NT) is a gut hormone secreted by specific endocrine cells scattered throughout the epithelial layer of the small intestine, which has been identified as an important mediator in several gastrointestinal functions and disease conditions. Its potential involvement in celiac disease (CD) has been investigated, but there are conflicting findings. The aim of this study was to evaluate serum NT levels in children with CD at diagnosis, compared to a control group, and to investigate whether NT correlated in CD patients with symptoms, antibody response, and intestinal mucosal damage. Materials and Methods. Children (1-16 years old) undergoing gastrointestinal endoscopy for CD or for other clinical reasons were included in this study. Patients with CD diagnosed according to the 2012 European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) guidelines without biopsy were also recruited. Fasting serum samples were analyzed for NT levels using ELISA. Logistic regression, Wilcoxon rank sum, and Spearman's rank tests were used for statistical analysis. Results Thirty children (18 females, 2.2-15.9 years old) were enrolled. Of 25 patients who underwent endoscopy, 9 were CD patients, 13 were controls, and 3 were excluded due to nonspecific inflammation at duodenal biopsy. CD was diagnosed in 5 patients without biopsy. NT median was higher in CD patients compared to controls (13.25 (IQR 9.4-17.5) pg/ml vs. 7.8 (IQR 7.6-10) pg/ml; p = 0.02). No statistically significant association between NT and clinical, serological, or histological data of CD was observed in this CD cohort. Conclusions To our knowledge, this is the first study that evaluates NT in CD children from Italy. Results show that NT is higher in the serum of CD children at diagnosis compared to controls. However, larger-scale studies are required to validate these findings. Whether serum NT levels can be an adjunctive marker for pediatric CD remains currently elusive.

Abstract
Celiac disease (CD) is a chronic autoimmune disease that occurs in genetically predisposed individuals in whom the ingestion of gluten leads to damage of the small bowel. It is estimated to affect 1 in 100 people worldwide, but is severely underdiagnosed. Currently available guidelines require CD-specific serology and atrophic histology in duodenal biopsy samples for the diagnosis of adult CD. In pediatric CD, but in recent years in adults also, nonbioptic diagnostic strategies have become increasingly popular. In this setting, in order to increase the diagnostic rate of this pathology, endoscopy itself has been thought of as a case finding strategy by use of digital image processing techniques. Research focused on computer aided decision support used as database video capsule, endoscopy and even biopsy duodenal images. Early automated methods for diagnosis of celiac disease used feature extraction methods like spatial domain features, transform domain features, scale-invariant features and spatio-temporal features. Recent artificial intelligence (AI) techniques using deep learning (DL) methods such as convolutional neural network (CNN), support vector machines (SVM) or Bayesian inference have emerged as a breakthrough computer technology which can be used for computer aided diagnosis of celiac disease. In the current review we summarize methods used in clinical studies for classification of CD from feature extraction methods to AI techniques.

[PMID: 30405092 PMCID: PMC6266734 DOI: 10.3390/nu10111705] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2018] [Revised: 10/21/2018] [Accepted: 11/05/2018] [Indexed: 12/19/2022] Open
Abstract
Background: There is evidence that digestive motor disorders are frequently present in untreated celiac disease (CD) patients. Similarly, non-celiac gluten sensitivity (NCGS) can be associated with gut motor disorders. In both cases, gut dysmotility can improve or be completely reversed with a gluten-free diet (GFD). Methods: A literature search for motility disorders in CD and NCGS patients was carried out using the online databases PubMed, Medline and Cochrane. Results: Esophageal, gastric, small bowel and gallbladder motor disorders are common in both children and adults with CD. Although the clinical consequences of these disorders are not clearly defined, gastric dysfunction could affect drug absorption and metabolism in the thyroid and neurological conditions associated with CD. The impact of a GFD on motility disorders is, however, controversial. No systematic studies are available on NCGS. NCGS frequently overlaps with irritable bowel syndrome (IBS) and similar pathophysiological mechanisms may be hypothesized. Conclusions: Mucosal damage may affect gut motility in untreated CD through perturbation of hormonal and neuro-immunomodulatory regulation. A persistent low-grade mucosal inflammation could explain the cases of persistent motor disorders despite a GFD. Further studies are needed to definitely assess the role of gut motor disorders in NCGS.

Abstract
Coeliac disease is an autoimmune mediated condition in response to gluten. A combination of innate and adaptive immune responses results in villous shortening in the small bowel (SB) that can be morphologically picked up on capsule endoscopy. It is the only imaging modality that can provide mucosal views of the entire SB, while histology is generally limited to the proximal SB. Radiological modalities are not designed to pick up changes in villous morphology. Areas covered: In this review, we provide a comprehensive analysis on the justified use of small bowel capsule endoscopy (SBCE) in the assessment of patients with coeliac disease; compare SBCE to histology, serology, and symptomatology; and provide an overview on automated quantitative analysis for the detection of coeliac disease. We also provide insight into future work on SBCE in relation to coeliac disease. Expert commentary: SBCE has opened up new avenues for the diagnosis and monitoring of patients with coeliac disease. However, larger studies with new and established coeliac disease patients and with greater emphasis on morphological features on SBCE are required to better define the role of SBCE in the setting of coeliac disease.

Abstract
BACKGROUND A link between small intestinal bacterial overgrowth (SIBO) and celiac disease (CD) has been hypothesized. METHODS Literature search was performed in main medical databases. Methods of analysis/inclusion criteria were based on Preferred Reporting Items for Systematic reviews and Meta-Analyses recommendations. The end-point was to estimate, by a pooled-data analysis, SIBO prevalence in CD. Proportions/percentages and their 95% confidence intervals (CI) were calculated by inverse variance method, whereas odd ratios (OR) and their 95% CI were estimated, where available, based on the Mantel-Haenszel method. Data were entered into the RevMan 5.3 software. KEY RESULTS Eleven articles fulfilled considered criteria. The pooled mean prevalence of SIBO in CD was 20% (95% CI of 10%-30%). In comparison to asymptomatic controls, CD was associated to higher risk of SIBO, with an OR of 10.52 (95% CI 2.69-41.21, P=.0007). Jejunal aspirate culture assessed SIBO prevalence of 11% (95% CI 3%-19%) in CD, whereas breath tests detected a higher value (23%, 95% CI 10%-37%). The pooled prevalence of SIBO in CD patients who were symptomatic despite a GFD was 28% (95% CI 10%-47%), higher than in asymptomatic celiac patients (pooled prevalence of 10%, with a 95% CI of 3%-16%), despite not statistically significant (P=.06). When GFD-unresponsive CD was defined only by clinical persistence of symptoms, the prevalence of SIBO was higher than in the case of villous atrophy association (31% vs 16% P=.33). CONCLUSIONS The heterogeneity of available studies may not support a relationship SIBO-CD. Nevertheless, SIBO could be more common in CD when symptoms do not improve after GFD.

Abstract
Objective Delayed gastric emptying has been frequently detected in patients with untreated celiac disease. According to several studies, gluten withdrawal showed to be effective in normalizing the gastric emptying rate. The aim of this study was to evaluate the gastric emptying rate of solids in patients with celiac disease before and after a gluten-free diet. Methods Twelve adult patients with celiac disease (age range 20-57 years) and 30 healthy controls (age range 30-54 years) underwent a (13)C-octanoic acid breath test to measure gastric emptying. Half emptying time (t1/2) and lag phase (tlag) were calculated. After at least 12 months of a gluten-free diet, celiac patients underwent a new (13)C-octanoic acid breath test. A symptom score was utilized to detect dyspeptic and malabsorption symptoms in all the patients. Results The gastric motility parameters, t1/2 and tlag, were significantly longer in patients than in controls. On a gluten-free diet, surprisingly, the gastric emptying did not normalize despite an improvement of symptom score. No significant correlation between abnormal gastric emptying and specific symptom patterns, anthropometric parameters or severity of histological damage was found. Conclusions This finding supports the hypothesis that gluten-driven mucosal inflammation might determine motor abnormalities by affecting smooth muscle contractility or impairing gut hormone function. The persistence of these abnormalities on a gluten free diet suggests the presence of a persistent low-grade mucosal inflammation with a permanent perturbation of the neuro-immunomodulatory regulation.

Abstract
BACKGROUND Coeliac disease (CD) has been linked to gastro-oesophageal reflux disease (GORD). Previous studies have demonstrated an increased prevalence of reflux in patients with CD. However data on the risk for CD in patients presenting with reflux are conflicting. AIMS The aim of this study was to establish the prevalence of CD in patients with GORD and to elucidate the mechanisms for reflux symptoms in newly diagnosed CD patients. METHODS Group A: patients who had undergone routine duodenal biopsy were prospectively recruited between 2004 and 2014. Diagnostic yield was compared with that of a screening cohort. Group B: 32 patients with newly diagnosed CD who had undergone oesophageal manometry and 24-h pH studies were prospectively recruited. RESULTS Group A: 3368 patients (58.7% female, mean age 53.4 years) underwent routine duodenal biopsy. Of these patients, 850 (25.2%) presented with GORD. The prevalence of CD among GORD patients was 1.3% (0.7-2.4%), which was not significantly higher than that in the general population (P=0.53). Within the context of routine duodenal biopsy at endoscopy (when corrected for concurrent symptoms, age and sex), reflux was found to be negatively associated with CD [adjusted odds ratio 0.12 (0.07-0.23), P<0.0001]. In group B, 34% of patients complained of reflux. On manometry, 9% had a hypotensive lower oesophageal sphincter and 40.6% had oesophageal motor abnormalities, with 25% significantly hypocontractile. On pH studies, 33% demonstrated reflux episodes. CONCLUSION The prevalence of undiagnosed CD among GORD patients is similar to that in the general population, and routine duodenal biopsy cannot be recommended. A significant number of patients with newly diagnosed CD were found to have reflux and/or oesophageal dysmotility on pH/manometry studies; this may explain the high prevalence of reflux symptoms in CD.

Abstract
Celiac disease (CD) is a complex autoimmune disorder in genetically predisposed individuals of all age groups triggered by the ingestion of food containing gluten. A reliable diagnosis is of high interest in view of embarking on a strict gluten-free diet, which is the CD treatment modality of first choice. The gold standard for diagnosis of CD is currently based on a histological confirmation of serology, using biopsies performed during upper endoscopy. Computer aided decision support is an emerging option in medicine and endoscopy in particular. Such systems could potentially save costs and manpower while simultaneously increasing the safety of the procedure. Research focused on computer-assisted systems in the context of automated diagnosis of CD has started in 2008. Since then, over 40 publications on the topic have appeared. In this context, data from classical flexible endoscopy as well as wireless capsule endoscopy (WCE) and confocal laser endomicrosopy (CLE) has been used. In this survey paper, we try to give a comprehensive overview of the research focused on computer-assisted diagnosis of CD. The state-of-the-art research in automated diagnosis of celiac disease is presented. A systematic review of methods and techniques used in this field is given. Specific issues and challenges in the field are identified and discussed.

Abstract
BACKGROUND & AIMS Patients with celiac disease (CD) often report symptoms compatible with irritable bowel syndrome (IBS). However, the prevalence of these symptoms in patients with CD and their relation to adherence to a gluten-free diet (GFD) have not been assessed systematically. METHODS We searched MEDLINE, EMBASE, and EMBASE Classic (through July 2012) to identify cross-sectional surveys or case-control studies reporting prevalence of IBS-type symptoms in adult patients (≥ 16 years old) with established CD. The number of individuals with symptoms meeting criteria for IBS was extracted for each study, according to case or control status and adherence to a GFD. Pooled prevalence and odds ratios (ORs), with 95% confidence intervals (CIs), were calculated. We analyzed data from 7 studies with 3383 participants. RESULTS The pooled prevalence of IBS-type symptoms in all patients with CD was 38.0% (95% CI, 27.0%-50.0%). The pooled OR for IBS-type symptoms was higher in patients with CD than in controls (5.60; 95% CI, 3.23-9.70). In patients who were nonadherent with a GFD, the pooled OR for IBS-type symptoms, compared with those who were strictly adherent, was 2.69 (95% CI, 0.75-9.56). There was also a trend toward a higher OR for IBS-type symptoms among patients who did not adhere to the GFD, compared with controls (12.42; 95% CI, 6.84-11.75), compared with that observed for adherent CD patients vs controls (4.28; 95% CI, 1.56-11.75). CONCLUSIONS IBS-type symptoms occur frequently in patients with CD and are more common than among controls. Adherence to a GFD might be associated with a reduction in symptoms.

Abstract
BACKGROUND Prior work has shown that videocapsule endoscopy image features are a useful tool for quantitatively distinguishing the intestinal mucosal surface of untreated celiac patients from that of controls. The use of dynamic estimates of wall motility may further help to improve classification. METHODS Videocapsule endoscopy clips (200 frames each, 2 frames/s, 576 × 576 pixels/frame) were acquired at five small intestinal locations in 11 untreated celiac patients (celiacs) and ten controls. Color images were converted to grayscale and analyzed frame-by-frame. Variations in the position and width of the center of the small intestinal lumen were quantitatively estimated. The darkest grayscale pixels were used as an estimate of the lumen center. Over 200 frames, the standard deviation of the lumen center xy position and the mean and standard deviation in lumen center width were used as dynamic estimates of wall motility. These parameters were plotted in three-dimensional space, and the best discriminant function was used to classify celiacs versus controls at each of the following five locations: (1) duodenal bulb, (2) distal duodenum, (3) jejunum, (4) ileum, and (5) distal ileum. RESULTS The overall sensitivity for the classification of celiacs versus controls at all five locations was 98.2 %, while the specificity was 96.0 %. From location 1 to 5, there was a tendency for the lumen center width to diminish in terms of frame-to-frame variability by 7.6 % in celiacs (r (2) = 0.4) and 9.7 % in controls (r (2) = 0.7). CONCLUSIONS In addition to examining the mucosal surface, videocapsule endoscopy can assess small bowel intestinal motility and aid in distinguishing celiac patients from controls.

Abstract
BACKGROUND Prior work has shown that videocapsule endoscopy image features are a useful tool for quantitatively distinguishing the intestinal mucosal surface of untreated celiac patients from that of controls. The use of dynamic estimates of wall motility may further help to improve classification. METHODS Videocapsule endoscopy clips (200 frames each, 2 frames/s, 576 × 576 pixels/frame) were acquired at five small intestinal locations in 11 untreated celiac patients (celiacs) and ten controls. Color images were converted to grayscale and analyzed frame-by-frame. Variations in the position and width of the center of the small intestinal lumen were quantitatively estimated. The darkest grayscale pixels were used as an estimate of the lumen center. Over 200 frames, the standard deviation of the lumen center xy position and the mean and standard deviation in lumen center width were used as dynamic estimates of wall motility. These parameters were plotted in three-dimensional space, and the best discriminant function was used to classify celiacs versus controls at each of the following five locations: (1) duodenal bulb, (2) distal duodenum, (3) jejunum, (4) ileum, and (5) distal ileum. RESULTS The overall sensitivity for the classification of celiacs versus controls at all five locations was 98.2 %, while the specificity was 96.0 %. From location 1 to 5, there was a tendency for the lumen center width to diminish in terms of frame-to-frame variability by 7.6 % in celiacs (r (2) = 0.4) and 9.7 % in controls (r (2) = 0.7).

Abstract
Background Various techniques for managing faecal evacuation have been proposed; however, colostomy irrigation is favoured as it leads to better patient outcomes. Alternative fluid regimens for colostomy irrigation have been suggested to achieve effective evacuation. Aim The objective of this review was to summarise the best available evidence on the most effective fluid regimen for colostomy irrigation. Search strategy Trials were identified by electronic searches of CINAHL, PubMed, MEDLINE, Current Contents, the Cochrane Library and EMBASE. Unpublished articles and references lists from included studies were also searched. Selection criteria Randomised controlled trials and before-and-after studies investigating any fluid regimen for colostomy irrigation were eligible for inclusion. Outcomes measured included fluid inflow time, total wash-out time, haemodynamic changes during irrigation, cramps, leakage episodes, quality of life and level of satisfaction. Data collection and analysis Trial selection, quality appraisal and data extraction were carried out independently by two reviewers. Differences in opinion were resolved by discussion. Main results The systematic literature search strategy identified two cross-over trials that compared water with another fluid regimen. Owing to the differences in irrigating solutions used, the results were not pooled for analysis. Both the polyethylene glycol electrolyte solution and glyceryl trinitrate performed significantly better than water. Conclusion There is some evidence to support the effectiveness of fluid regimens other than water, such as polyethylene glycol electrolyte and glyceryl trinitrate, for colostomy irrigation. Further well-designed clinical trials are required to establish solid evidence on the effectiveness of other irrigating solutions that might enhance colonic irrigation.

Abstract
BACKGROUND Alterations of small intestinal transit and gallbladder (GB) motility have been reported in celiac disease (CD) in studies involving, in most cases, non-physiological experimental conditions and artificial stimuli to motility. Our aims were to quantitate non-invasively small intestinal transit time and GB emptying during administration of a physiological and palatable solid meal, and to assess the effect of gluten-free diet (GFD). METHODS We simultaneously measured mouth-to-cecum transit time (MCTT) using a validated H(2) breath test, and GB motility using ultrasonography. We studied CD patients before (n = 19) and during (n = 14) GFD, and healthy volunteers (n = 24) following administration of a physiological solid meal (Kcal 539). KEY RESULTS Mouth-to-cecum transit time was more prolonged in CD (mean ± SEM: 235 ± 96 min) than in controls (169 ± 65 min, P = 0.0039). The GB fasting volume and postprandial residual volume were significantly higher in CD than in controls, and GB emptying constant was slower in CD than in controls. During GFD, GB emptying reverted to normal, but MCTT remained unchanged (229 ± 69 min) and more prolonged in CD than in controls (P = 0.0139). During GFD, duodenal infiltration with lymphocytes and mast cells persisted higher than that in controls, and the number of mast cells lying in proximity of nervous endings did not change. CONCLUSIONS & INFERENCES Slow postprandial MCTT in response to a physiological meal does not revert to normal during GFD, an effect mirroring incomplete histopathologic recovery.

Abstract
Celiac disease (CD) may often be associated with various motor disorders affecting the different segments of the digestive tract, including the esophagus. Although it has not been universally reported, some available evidences indicate that pediatric and adult celiac patients could manifest a higher frequency of esophagitis and gastroesophageal reflux disease-related symptoms compared to nonceliac patients. In addition, several published studies have consistently shown the efficacy of a gluten-free diet in rapidly controlling esophageal symptoms and in preventing their recurrence. Since the participation of gluten in the esophageal symptoms of CD seems clear, its intimate mechanisms have yet to be elucidated, and several hypothesis have been proposed, including the specific immune alterations characterizing CD, the reduction in nutrient absorption determining the arrival of intact gluten to distal gastrointestinal segments, and various dysregulations in the function of gastrointestinal hormones and peptides. Recent studies have suggested the existence of a possible relationship between CD and eosinophilic esophagitis, which should be more deeply investigated.

Abstract
To investigate the features of the gastric interdigestive pressure activity under normal physiological conditions, we have developed the wireless radiotelemetry capsule based on a telemetry technique. Twelve healthy volunteers participated in this study. Pressure activity data which are an important index of gastric motility can be obtained from the wireless radiotelemetry capsule. But the capsule only records single-dimensional pressure time series which may contain a few interdependent components simultaneously. Automated embedding phase space reconstruction algorithm is employed to reconstruct multi-dimensional phase space. Then the dominant and separated component of the gastric contractions is identified using FastICA algorithm. Finally the use of Hilbert Huang transform method for analyzing the characters of gastric motility is investigated. The results show that the proposed method is an effective approach for the analysis of the gastric pressure series.

Abstract
BACKGROUND AND AIM Patients with celiac disease may present with abnormal upper gut motor activity. However, it is not known if these abnormalities persist after the introduction of a gluten-free diet. The present study aimed to compare antroduodenojejunal motor variables recorded in untreated celiac patients with those of celiac patients given a gluten-free diet and healthy volunteers. METHODS Eleven untreated celiac disease patients, 12 age- and sex-matched celiac patients on a gluten-free diet (at least 12 months), and 33 controls entered the study. Antroduodenojejunal motility was recorded for 6 h during fasting and for 3 h after a standard meal by means of a perfused, multiple lumen catheter. RESULTS More than 80% of untreated celiac patients had discrete motor abnormalities of the upper gut, in both fasting and fed recordings, compared to the other subjects. Patients on a gluten-free diet also showed motor abnormalities, albeit to a lesser extent. In these patients histological evaluation showed the persistence of mild mucosal abnormalities. CONCLUSIONS Upper gut motor abnormalities are frequent in patients with celiac disease, even in those on a gluten-free diet. In the latter group, these abnormalities may suggest an incomplete adherence to the dietary regimen.

Abstract
PURPOSE OF REVIEW The aim of this article is to review recently published studies presenting novel and relevant information on small intestinal motility. RECENT FINDINGS The reviewed studies covered a variety of topics with several themes emerging. The presentation and causes of chronic intestinal dysmotility continue to expand. Evidence continues to accrue that at least a subset of patients with severe colonic inertia may have a more diffuse motility disorder highlighting the need for careful assessment prior to embarking on surgery for refractory constipation. While interest in bacterial overgrowth in irritable bowel syndrome continues, the utility and specificity of lactulose hydrogen breath testing is yet again being called into question. Methane appears to slow intestinal transit and constipation appears more common among methane-positive patients. The association is presently only correlative and further study is needed. SUMMARY Small intestinal motility remains an understudied area. Recent publications provide additional new information related to physiology and pathophysiology of small bowel motility. These findings should be of interest to clinician and investigator alike.

Abstract
AIM: To investigate the prevalence of celiac disease serologic markers (antigliadin IgA, IgG, and anti-endomysial IgA) in patients with reflux esophagitis and to detect the relationship between reflux esophagitis and celiac disease (CD).
METHODS: This study was performed prospectively between January 2003 and January 2004. Sixty-eight adult reflux esophagitis patients and 40 people as control group for symptoms related with gastrointestinal system were enrolled in this study. The diagnostic work-up included an accurate medical history with gastrointestinal symptoms, routine laboratory measurements, the detection of antibodies against gliadin (IgA and IgG) and endomysium (IgA), and an upper endoscopy with postbulbar biopsy.
RESULTS: IgA-AGA and IgG-AGA were positive at 8.8% and 10.3% in patients with reflux esophagitis. In control group, it was found that 10% people had positive IgA-AGA, and 7.5% people had positive IgG-AGA. There was no significant relationship between patients and control group regarding positive IgA-AGA and IgG-AGA. The patients and persons in control group had no positive IgA-EMA. On postbulbar biopsies, no finding was detected concerning celiac disease. There were no symptoms and signs for gluten enteropathy in patients and control group.
CONCLUSION: This review supports that an association does not exist between celiac disease and reflux esophagitis. We think these diseases exist independently from each other.

Abstract
Celiac disease is common and can present with nonspecific upper gastrointestinal symptoms. Patients may therefore undergo esophagogastroduodenoscopy as their initial investigation. Markers of villous atrophy, which can be seen in the duodenum during endoscopy, are well described. They have limited sensitivity for patients with mild enteropathy and duodenal biopsies should be performed if there is strong suspicion of celiac disease irrespective of endoscopic appearance. Endoscopic markers do, however, allow the selection of patients with nonspecific symptoms for duodenal biopsy, and these markers should, therefore, be looked for routinely during esophagogastroduodenoscopy.

Abstract
In the past inflammatory bowel disease (IBD), celiac disease and irritable bowel syndrome (IBS) were regarded as completely separate disorders. Now, with the description of inflammation, albeit low-grade, in IBS, and of symptom overlap between IBS and celiac disease, this contention has come under question. Is there true overlap between these disorders? Despite the limitations of available data one cannot but be struck by some areas of apparent convergence: IBD and celiac disease in remission, lymphocytic colitis and microscopic inflammation in IBS, in general, and, especially, in the post-infectious IBS category. The convergence between latent celiac disease and sub-clinical IBD, on the one hand, and IBS, on the other, appears, based on available evidence, to be somewhat spurious and may largely relate to misdiagnosis, a phenomenon which may also explain the apparent evolution of IBS into IBD in some studies. Similarities between IBS and lymphocytic colitis are more striking and less readily dismissed; as for IBS, well documented instances of progression of lymphocytic colitis to full-blown IBD are infrequent, suggesting a true separation between this disorder and classical IBD. Do IBS and lymphocytic colitis represent different responses to similar triggers? Will some of the 'inflamed' IBS subgroup be reclassified as part of the spectrum of lymphocytic colitis in the future? Will inflammation emerge as a common underlying factor in the pathogenesis of IBS? The answer to these and many questions must await further study of this fascinating area.

Abstract
Previous studies on celiac patients demonstrated that exposure to gliadin alters the motility of the upper gastrointestinal tract, leading to increased acid reflux. No literature is available regarding the possible presence of specialized intestinal metaplasia of the esophagus as a consequence of chronic reflux in adult celiac patients. Our purpose was to evaluate endoscopically and histologically the esophagi of a group of untreated celiac patients. We studied 60 celiac patients, 13 men and 47 women (mean age, 40 +/- 14 [SD] years; range, 18-80 years), at their first endoscopy (following a normal diet). The distal esophagus was evaluated and multiple biopsies were taken. Hematoxylin-eosin and alcian blue stainings were performed. A group of nonceliac, age- and sex-matched patients was used as a control. We found intestinal metaplasia in the distal esophagus of 16 of 60 (26.6%) celiacs (mean age, 45 +/- 13 years; range, 27-75 years), in comparison with a control-group prevalence of 10.9% (OR, 3.9; 95% CI, 1.4-11.2%). Among the celiac group with metaplasia, only one patient had reflux-like symptoms. None had esophagitis. In conclusion, we observed an increased prevalence of esophageal metaplasia in patients with celiac disease. This finding could be the result of motor abnormalities leading to chronic acid reflux, combined with a mucosa which is sensitive to gliadin.

Abstract
PURPOSE Water for colostomy irrigation is largely absorbed by the colon, which may result in less efficient expulsion of stool. This study compared the outcome of colonic cleansing with water and polyethylene glycol solution. METHODS In a cross-over study, 41 colostomy irrigators were randomly assigned to water or polyethylene glycol solution irrigation first and then the other regimen, each for one week. Patients recorded fluid inflow time, total washout time, cramps, leakage episodes, number of stoma pouches used, and satisfaction scores (Visual Analog Scale, 1-10: 1 = poor, and 10 = excellent). The median and interquartile range for each variable was calculated, and the two treatments were compared (Wilcoxon's test). RESULTS Eight patients failed to complete the study. Thirty-three patients (20 females; mean age, 55 (range, 39-73) years) provided 352 irrigation sessions: water (n = 176), and polyethylene glycol solution (n = 176). Irrigation was performed every 24, 48, and 72 hours by 17, 9, and 7 patients respectively, using 500 ml (n = 1), 750 ml (n = 2), 1,000 ml (n = 16), 1,500 ml (n = 11), 2,000 ml (n = 2), and 3,500 ml (n = 1) of fluid. The median and interquartile range for water vs. polyethylene glycol solution were: fluid inflow time (6 (range, 4.4-10.8) vs. 6.3 (range, 4.1-11) minutes; P = 0.48), total washout time (53 (range, 33-69) vs. 38 (range, 28-55) minutes; P = 0.01), leakage episodes (2.3 (range, 1.7-3.8) vs. 0.7 (range, 0.2-1); P < 0.001), satisfaction score (5.8 (range, 4-7.5) vs. 8.8 (range, 8.3-10); P < 0.001), and stoma pouch usage per week (75 (range, 45-80) vs. 43 (range, 0-80); P = 0.008). No difference was demonstrated for frequency of cramps ( P = 0.24). CONCLUSIONS Polyethylene glycol solution performed significantly better than water and may be a superior alternative fluid regimen for colostomy irrigation.

Abstract
It is quite frequent to recognize celiac patients who show gastrointestinal motor abnormalities in clinical practice. In fact, in 30 to 60% of patients, physical examination and dyspeptic symptoms (epigastric discomfort, early satiety) suggest a gastrointestinal motility disorder. Consistent data are now available on the presence of a disturbed motility of the esophagus, stomach, small intestine, gallbladder, and colon of untreated celiac patients. Gastrointestinal abnormalities differ in different gastrointestinal districts. In fact, esophageal transit, gastric and gallbladder emptying, and orocecal transit time are delayed, while colonic transit is faster. These findings are related to the complex interactions among reduced absorption of food constituent (in particular, fat), neurologic alteration, and hormonal derangement. Motility disorders of the gut are also a predisposing factor in the development of small intestinal bacterial overgrowth and may contribute both to development of symptoms in some untreated celiacs and to the persistence of symptoms after gluten-free diet in some of them. All these alterations fortunately disappear after gluten-free diet, and patients return to well being status. Whatever the initial event in the pathogenesis of the celiac lesions may be, we know for certain at this time that gastrointestinal disturbances play an important role in the genesis of gastrointestinal symptoms in celiac disease and that surveillance for celiac disease in patients complaining of dysmotility-like dyspeptic symptoms should be increased.

Abstract
BACKGROUND There are various, well-documented, duodenal endoscopic markers caused by the villous atrophy of celiac disease. Another abnormality seen in association with villous atrophy, erosions in the second part of the duodenum, is described. To our knowledge, this finding has not been heretofore described in patients with celiac disease. METHODS Five patients with celiac disease and erosions were encountered over a period of 2 years. OBSERVATIONS The erosions were multiple, superficial, and present in the second part of the duodenum but not the duodenal bulb. All 5 patients had findings typical of celiac disease (iron deficiency, osteopenia/osteoporosis), and 4 had at least one other endoscopic marker: scalloped duodenal folds (3), fold loss (2), or mosaic pattern mucosa (2). These patients represented 7% of new cases of celiac disease during the same time period. This pattern of erosion was not observed in over 1200 other patients undergoing upper endoscopy during the study period. CONCLUSIONS In a European population, the finding of erosions confined to the second part of the duodenum is specific for villous atrophy, although sensitivity is low. Erosions in the second part of the duodenum should be added to the list of endoscopic markers of celiac disease.

Abstract
OBJECTIVE Celiac disease is a gluten-sensitive enteropathy with a broad spectrum of clinical manifestation, and most celiac patients respond to a gluten-free diet (GFD). However, in some rare cases celiacs continue to experience GI symptoms after GFD, despite optimal adherence to diet. The aim of our study was to evaluate the causes of persistence of GI symptoms in a series of consecutive celiac patients fully compliant to GFD. METHODS We studied 15 celiac patients (five men, 10 women, mean age 36.5 yr, range 24-59 yr) who continued to experience GI symptoms after at least 6-8 months of GFD (even if of less severity). Antigliadin antibody (AGA) test, antiendomysial antibody (EMA) test, and sorbitol H2-breath test (H2-BT), as well as esophagogastroduodenoscopy (EGD) with histological evaluation, were performed before starting GFD. Bioptic samples were obtained from the second duodenal portion during EGD, and histopathology was expressed according to the Marsh classification. To investigate the causes of persistence of GI symptoms in these patients, we performed AGA and EMA tests, stool examination, EGD with histological examination of small bowel mucosa, and sorbitol-, lactose-, and lactulose H2-breath tests. RESULTS Histology improved in all patients after 6-8 months of GFD; therefore, refractory celiac disease could be excluded. One patient with Marsh II lesions was fully compliant to his diet but had mistakenly taken an antibiotic containing gluten. Two patients showed lactose malabsorption, one patient showed Giardia lamblia and one patient Ascaris lumbricoides infestation, and 10 patients showed small intestinal bacterial overgrowth (SIBO) by lactulose H2-BT. We prescribed a diet without milk or fresh milk-derived foods to the patient with lactose malabsorption; we treated the patients with parasite infestation with mebendazole 500 mg/day for 3 days for 2 consecutive wk; and we treated the patients with SIBO with rifaximin 800 mg/day for 1 wk. The patients were re-evaluated 1 month after the end of drug treatment (or after starting lactose-free diet); at this visit all patients were symptom-free. CONCLUSIONS This study showed that SIBO affects most celiacs with persistence of GI symptoms after gluten withdrawal.

Abstract
Celiac disease (CD) is characterized by mucosal villous atrophy mostly confined to the proximal small intestine. Upper-gut motor abnormalities have been reported. Motilin, localized in cells in the proximal small intestine, is a trigger factor for the migrating motor complex. Plasma levels of motilin were studied in 16 untreated CD patients and in an age-matched control group of 18 healthy subjects by radioimmunoassay and by high-performance liquid chromatography (HPLC). The fasting levels of motilin and postprandial levels were significantly higher in CD patients compared to controls (P<0.01) and HPLC revealed a divergent individual pattern of the motilin fragments.

Abstract
OBJECTIVES Previous reports have linked irritable bowel syndrome (IBS) etiologically with various forms of mucosal inflammation, including infectious enterocolitides and inflammatory bowel disease. The mechanism is uncertain but may involve sensitization by inflammatory mediators. The enteropathy of celiac disease has theoretical advantages as a study model because it can be controlled with dietary gluten exclusion; however, whether it also predisposes to functional bowel disorders is unclear. Therefore, we assessed the prevalence of IBS-type symptoms in adult celiac patients and correlated this with dietary compliance with gluten exclusion. METHODS Adult patients (n = 150; 106 women and 44 men) with confirmed celiac disease were randomly selected from a computerized database of >350 patients, and were asked to complete a bowel questionnaire and the Short Form 36 Health Survey (SF-36). The control group (n = 162; 133 women and 29 men) had no history of celiac disease and had similar mean age and sex profile. RESULTS Of 150 celiac patients reviewed, 30 of 150 (20%) fulfilled the Rome criteria compared with eight of 162 (5%) ontrols. Of the celiac patients 10 of 46 (22%) had partial or no compliance with a gluten-free diet, whereas 20 of 104 patients (19%) adhered to the diet; this difference did not achieve statistical significance. Celiac patients with IBS-type symptoms had a markedly lower quality of life than those without, all eight domains being impaired to a clinically significant extent. Dietary gluten exclusion improved QOL in four of eight scales measured. CONCLUSIONS The hypothesis that mucosal inflammation in celiac disease may have a sensitizing effect or may predispose to IBS-type symptoms is supported by these results. Failure to attain optimal subjective well-being is common in celiac patients, particularly in those with coexisting IBS. Compliance with a gluten-free diet confers some benefit.

Abstract
BACKGROUND Few data are available on disturbed gastric emptying in patients with coeliac disease. The aims of the study were to investigate (a) the presence of delayed gastric emptying: (b) the acute effect on gastric emptying of gliadin; and (c) the effect of jejunal recovery on gastric emptying of meals with or without gluten in such patients. METHODS We measured gastric emptying of two meals in 16 patients with coeliac disease; one meal contained gliadin. Results were compared with those obtained in 24 controls. In 12 patients, both measurements were repeated after mucosal recovery. Statistical analysis was performed using the analysis of variance for repeated measurements and Student's t test. Mean +/- 1 s(mean) (standard error of the mean) are shown. RESULTS No difference was found in fasting and in maximal antral sections after the two meals. On entry, gastric emptying was significantly (P < 0.001) delayed compared to controls both after the meal containing gluten (326.9 +/- 12.4 min versus controls 213.5 +/- 11.5) and after the gluten-free meal (315.3 +/- 16.7 min). After jejunal recovery, emptying of the meal containing gluten remained unchanged (337 +/- 18.9 min), whereas emptying of the gluten-free meal was significantly shortened (280.6 +/- 10.5 min; P < 0.001). CONCLUSIONS In coeliac disease there is an impairment of gastric emptying which is at least partially reversible. This suggests either an immunological disorder or that unabsorbed meal constituents are responsible for an ileal-brake effect.

Abstract
OBJECTIVE Endoscopic markers of duodenal villous atrophy (VA) can facilitate diagnosis of celiac disease during routine upper GI endoscopy. We studied their sensitivity for VA in a large series of patients undergoing GI endoscopy specifically for duodenal biopsy. Poor sensitivity in this setting would have significant and adverse implications for their performance during routine endoscopy. METHODS All patients with VA on duodenal biopsy performed for positive serum endomysial antibody (EmA) and/or clinical features suggestive of celiac disease were included. The second part of duodenum was inspected carefully for endoscopic markers using videogastroscopes. RESULTS Of 129 patients studied, 99 (77%) had at least one endoscopic markers. The most commonly seen marker were a mosaic pattern mucosa (68 patients, 53%) and scalloping of duodenal folds (74 patients, 57%). The prevalence of markers was significantly lower for partial VA (15 of 26 patients, 58%) than for subtotal or total VA (84 of 103 patients, 82%) (p < 0.02). CONCLUSIONS Endoscopic markers have disappointing sensitivity even in a population at high risk of celiac disease, particularly for partial VA. Their performance may be even poorer in an unselected dyspeptic population. Although they may help improve diagnosis rates among patients with nonspecific dyspeptic symptoms, many patients, particularly those with milder enteropathy, will be missed. As celiac disease is an important cause of dyspepsia, consideration should be given to serological screening to further improve diagnosis rates, as few centers will have the resources to routinely biopsy all patients.

Abstract
In patients with chronic pancreatitis (CP) the relation among exocrine pancreatic secretion, gastrointestinal hormone release, and motility is disturbed. We studied digestive and interdigestive antroduodenal motility and postprandial gut hormone release in 26 patients with CP. Fifteen of these patients had pancreatic insufficiency (PI) established by urinary para-aminobenzoic acid test and fecal fat excretion. Antroduodenal motility was recorded after ingestion of a mixed liquid meal. The effect of pancreatic enzyme supplementation was studied in 8 of the 15 CP patients with PI. The duration of the postprandial antroduodenal motor pattern was significantly (P < 0.01) prolonged in CP patients (324 +/- 20 min) compared with controls (215 +/- 19 min). Antral motility indexes in the first hour after meal ingestion were significantly reduced in CP patients. The interdigestive migrating motor complex cycle length was significantly (P < 0.01) shorter in CP patients (90 +/- 8 min) compared with controls (129 +/- 8 min). These abnormalities were more pronounced in CP patients with exocrine PI. After supplementation of pancreatic enzymes, these alterations in motility reverted toward normal. Digestive and interdigestive antroduodenal motility are abnormal in patients with CP but significantly different from controls only in those with exocrine PI. These abnormalities in antroduodenal motility in CP are related to maldigestion.

Abstract
BACKGROUND Upper gastrointestinal motor abnormalities could account for some of the dyspeptic symptoms of celiac patients. However, the data on gastric emptying time are conflicting, and the pathophysiology of motor disturbances is still unclear. Neurotensin modulates upper gastrointestinal motor activity, and its postprandial increase is a reliable index of nutrient delivery to the ileum. We therefore assessed both plasma neurotensin levels and gastric emptying in untreated celiacs. METHODS The gastric antral area of nine untreated celiac patients and nine controls was measured with ultrasound at base line and every 30 min after a fatty meal (227 kcal, 45% fat); the base-line and postprandial neurotensin plasma levels were determined by means of radioimmunoassay. The data are mean values +/- standard deviation and were analyzed by using non-parametric tests. RESULTS The overall and half gastric emptying time were significantly longer in the patients (203+/-32 versus 133+/-15 min, P = 0.0117, and 137+/-32 versus 78+/-11 min, P = 0.0001). The pattern of the changes in antral area was similar in both groups during the observation period as a whole but differed significantly in the first 120 min (P = 0.0343). Base-line neurotensin levels were significantly higher in the patients (41.6+/-23.9 versus 18.2+/-5.5 pg/ml, P = 0.0214) and their net postprandial increase was lower than in controls (15.0+/-15.9 versus 29.8+/-13.0 pg/ml, P = 0.046). In both groups the base-line neurotensin levels were related to the half gastric emptying time (P = 0.023). CONCLUSIONS In untreated celiac patients gastric emptying time is longer than in controls and is concomitant with an increase in base-line plasma neurotensin levels.

Abstract
OBJECTIVE The aim of this study was to determine the prevalence of duodenal villous atrophy (VA) among patients undergoing routine upper gastrointestinal (GI) endoscopy and the value of endoscopic markers for VA in selecting patients for duodenal biopsy. METHODS One hundred and fifty adult patients with upper GI symptoms or iron-deficiency anemia had inspection and biopsy of the second part of the duodenum during endoscopy. Endoscopic markers for VA sought were mosaic or nodular mucosa, scalloping of duodenal folds, and reduction in number or absence of duodenal folds. RESULTS Endoscopic markers were seen in seven patients (5%): scalloped folds with mosaic pattern mucosa (three patients), scalloped folds, reduced in number with mosaic pattern mucosa (three patients), and nodular mucosa with reduction in fold numbers (one patient). All seven patients had partial, subtotal, or total VA. One of 143 patients with no endoscopic abnormality had patchy VA. The prevalence of VA was thus 1:19 (8 of 150). Endoscopic markers had a sensitivity of 87.5% (7 of 8), specificity of 100% (142 of 142), positive predictive value of 100% (7 of 7), and negative predictive value of 99% (142 of 143). Of the eight patients with VA, the indications for endoscopy were upper GI symptoms in seven patients (two with anemia) and anemia without GI symptoms in one. After 6 months of dietary gluten exclusion, improvement by at least one criterion was documented in all eight patients. CONCLUSIONS Careful inspection of the duodenum during routine upper GI endoscopy allows accurate selection of patients for biopsy but may not detect patchy VA or milder enteropathy. Celiac disease should be considered as a cause of dyspeptic and reflux symptoms, as well as of iron-deficiency anemia.

Abstract
The physiology and pathophysiology of small bowel motility are reviewed with particular focus on the motility patterns and periods that are detected by intraluminal manometry. Motility patterns are groups of phasic pressure waves resulting from contractions of the circular muscle layer of the small bowel that are organized by the enteric nervous system. Phase III of the migrating motor complex, the hallmark of the fasting motility period, thus reflects enteric neuromuscular function. Response to meal challenge also involves the CNS, reflexes beyond the gut and endocrine responses. Although specific disease diagnosis cannot be made by motility studies of the small bowel, the functional integrity is revealed. The normal occurrence of the essential patterns and periods of motility and the absence of distinctly abnormal patterns evidence preserved function, whereas the opposite indicates clinically significant dysmotility. Certain motility patterns are occasionally seen both in health and disease, and increased prevalence indicates a moderate dysfunction of yet unclear significance. Bacterial overgrowth with Gram-negative bacilli is the consequence of severe small bowel dysmotility, and a diagnosis that can be predicted by a motility study. Testing can be useful in the clinical management of paediatric and adult patients also by predicting the prognosis and response to enteral nutrition and medical therapy. Further studies are, however, needed to take full advantage of motility testing in clinical practise.

Abstract
OBJECTIVE A high prevalence of reflux esophagitis in celiac children and gut motor disorders in adult patients have been described. The aim of this study is to investigate the prevalence of esophageal symptoms and the esophageal motility pattern in adult celiac patients before and after gluten-free diet. METHODS In 22 consecutive adult celiac patients, before and after gluten-free diet, and in controls we calculated an esophageal symptom score regarding heartburn, regurgitation, dysphagia, and chest pain, and performed esophageal manometry using a constantly perfused multilumen catheter. RESULTS Patients were divided into two groups: with and without steatorrhea. Before gluten-free diet, the prevalence of esophageal symptoms was 45.5 % in all patients, but was significantly higher in patients with steatorrhea than in those without and in 44 control subjects (80% vs 16.7% and 27%, p < 0.05). Lower esophageal sphincter pressure was 17.5+/-5.3 in all patients, but was significantly lower in patients with steatorrhea than in patients without steatorrhea and 11 controls subjects (13.1+/-4.1 vs 21.0+/-2.9 and 20.7+/-3.7 mm Hg (mean+/-SD, p < 0.05). After the diet, the prevalence of esophageal symptoms diminished in all patients (9% vs 45.4%, p < 0.05) and lower esophageal sphincter pressure, measured in 13 patients, increased (19.0+/-3.7 vs 15.7+/-5.3 mm Hg, p < 0.05). CONCLUSION Adult celiac patients with steatorrhea present a higher prevalence of esophageal symptoms and a lowered lower esophageal sphincter pressure compared with celiac patients without steatorrhea and control subjects, but these phenomena can be reverted to control levels by gluten-free diet.

Abstract
Data from animal studies suggest that NSAIDs-induced gastric damage may be due to increased gastric motility. Such a mechanism, however, has never been tested or demonstrated in man. We evaluated the effects of two frequently prescribed NSAIDs, indomethacin and diclofenac sodium, on postprandial gastric motor activity (a physiologically reproducible stimulus) in healthy volunteers to see whether these compounds increase gastric motility. Twenty-four healthy volunteers of both sexes, 21-35 years of age, underwent a basal gastric motility recording. Thereafter, they were randomized in three groups to receive either placebo, indomethacin (50 mg three times a day) or diclofenac sodium (50 mg three times a day) for a week. At the end of the week, they underwent an identical manometric study. Analysis of the motility tracings showed no difference in gastric antral motility index and in amplitude of gastric antral contractions after NSAIDs with respect to the basal study and to the placebo group. About 50% of subjects (two in the placebo group) complained of side effects. These were transient and mild, except in two subjects taking indomethacin, in whom endoscopy was necessary; one of these had a small prepyloric ulcer. It is concluded that in man NSAID-related gastric damage is unlikely to be due to increased gastric motility.

Abstract
BACKGROUND Coeliac disease may present with dyspepsia or reflux. There are characteristic duodenal appearances associated with villous atrophy (mosaic pattern mucosa and loss, reduction in number or scalloping of duodenal folds) which may prompt small-bowel biopsy during routine upper gastrointestinal endoscopy. These appearances were sought in patients referred by their general practitioners for open-access endoscopy (OAE), to determine the prevalence and significance of coeliac disease as a cause of symptoms. METHODS Five hundred consecutive patients undergoing OAE by one consultant gastroenterologist were studied. Forceps biopsy specimens from the distal duodenum were taken if appearances were suggestive. If villous atrophy was confirmed, the response of symptoms to dietary gluten exclusion was assessed. RESULTS Ten patients had suggestive endoscopic appearances, of whom eight had villous atrophy, giving a prevalence of coeliac disease of 1.6% (1:63). All eight had mosaic pattern mucosa, with three also having reduction of duodenal folds, and four having scalloped folds. All had serum endomysial antibodies (EmA). Apart from diarrhoea, described by one patient, there were no symptoms of 'typical' coeliac disease at diagnosis: three patients were overweight. After dietary gluten exclusion all reported symptomatic improvement, with disappearance of EmA in five patients to date. CONCLUSIONS There is a high prevalence of coeliac disease among patients undergoing OAE, which is relevant to their clinical symptoms and which can be identified by careful endoscopic inspection of the duodenum.

Abstract
OBJECTIVE To investigate the relationship between esophageal function and the extent of disease in a nonselected group of scleroderma patients, and to study gastric and small bowel motility in a group of scleroderma patients with more severe clinical manifestations. METHODS Esophageal function in 125 scleroderma patients was investigated by radiologic, endoscopic, manometric, and pH-metric techniques. Ten patients also underwent gastrointestinal (GI) manometric recording, both during fasting and after a standard meal. RESULTS Radiologic abnormalities of the esophagus were found in 55 of 81 patients (68%) and esophagitis in 45 of 125 (36%). No significant relationship was disclosed between GI symptoms, radiologic abnormalities, esophagitis grade, and the various disease subsets. However, the overall incidence of endoscopic esophagitis (irrespective of the degree) was significantly (P < 0.05) correlated with the patient subgroups, with 100% incidence of esophagitis in those having the more severe cutaneous involvement (type III). Manometric abnormalities were documented in 80% of patients, and pathologic reflux in 78%. The severity of esophageal abnormalities on manometry significantly correlated with the severity of the disease, whereas no correlations were found with pH-metric data. Ninety percent of the 10 female patients undergoing antroduodenal manometry displayed abnormal findings; of these, 60% showed neuropathic, and 30% myopathic, patterns. The latter were recorded in patients with a more severe stage of the disease (type III). CONCLUSION A direct relationship was observed between scleroderma subsets and the severity of esophageal (and, probably, more distal gut) motor involvement. Since no correlation was found between esophageal symptoms and the severity of manometric abnormalities, manometry should be considered the single most important GI test to document the severity of the "esophageal" disease. Gastric and small bowel manometry may also offer evidence of widespread gut involvement, and provide a rationale for a more targeted therapeutic approach.

Abstract
Recent evidence indicates that patients complaining of severe chronic idiopathic constipation may have motor abnormalities not limited to the colon. We studied by manometric means gastric and small bowel motility in a homogeneous group of patients with chronic idiopathic constipation, ie, the slow transit type. Twenty-one patients were recruited for the study and compared to 33 healthy subjects. Manometric examination was carried out for about 5 hr fasting and 1 hr after a standard meal. Analysis of the manometric tracings revealed during fasting no abnormalities in number and configuration of migrating motor complex with respect to controls. However, in 70% of patients motor abnormalities were detected, represented by bursts of nonpropagated contractions and discrete clustered contractions. After feeding, the patient group displayed a significantly shorter antral motor response to the meal with respect to controls; moreover, intestinal bursts of nonpropagated contractions were found in 19% of patients, and 14% of them had an early return of the activity fronts. We conclude that patients with slow transit constipation frequently display motor abnormalities of the upper gut. These findings further strengthen the concept that this condition may represent a panenteric disorder.

Abstract
Coeliac sprue is a relatively frequent disease with protean clinical manifestations. Recent studies suggest that gastrointestinal motor abnormalities may explain some symptoms complained of by such patients. We investigated whether coeliac patients have oesophageal motor abnormalities from both a clinical and a physiological point of view. Thirty-six consecutive adult sprue subjects (14 during the florid phase and 22 on gluten-free diet) were studied. A clinical questionnaire on gastrointestinal symptoms (with emphasis on those of oesophageal origin) was administered. Moreover, 18 patients (13 on free and five on gluten-free diet) gave their consent for oesophageal manometry and eight subjects for pH-metry also. Oesophageal clinical symptoms were compared with those of 144 age- and sex-matched controls from a general population sample, and manometry with that of 34 healthy volunteers. Of coeliac patients 50% complained of dysphagia (P < 0.001 vs. controls) and 14% noncardiac chest pain (P = NS vs. controls). Manometric examination showed motor abnormalities in 67% of the subjects examined, consisting of nutcracker oesophagus, hypotonic lower oesophageal sphincter associated with simultaneous contractions, and frequent repetitive (> 3 peaks) contractions. These abnormalities were equally distributed among free and gluten-free diet patients. pH-metry showed only one pathological reflux out of eight subjects studied. We conclude that patients with coeliac sprue may display abnormal oesophageal motility. This confirms previous studies suggesting that gastrointestinal motor abnormalities should probably be added to the clinical spectrum of the disease.

Abstract
From the point of view of its motor activity, the human colon is probably the least understood of the abdominal hollow viscera. This is due to several facts: a) its proximal portions are relatively inaccessible due to anatomical reasons; b) there is no reliable animal model due to the considerable anatomic-physiological differences among mammals. For instance, most deductions about human colonic motor activity have been drawn from experiences in cats and dogs, in which the colon displays a cecum which is almost atrophic, and the viscus is featureless and C-shaped, without the haustrations and the sharp angulations seen in man, c) the wide fluctuations of motility in the daily time course of the same individual makes the interpretation of many studies difficult, especially considering the fact that, until recently, most of the studies on human colonic motility have been conducted for relatively short (30-180 min) recording periods. Recently, however, techniques that allow recording from the proximal portions of the human colon have been developed, and prolonged (24 h or more) observations of myoelectrical and contractile events have been achieved, thus improving our knowledge of the normal physiologic properties of the viscus. These informations have furthermore been integrated and confirmed by scintigraphic techniques (less invasive), that allow the measurement of intracolonic flow activity. The purpose of the present paper is to review the physiological aspects of colonic motility in man, quoting animal studies where human ones are lacking. We will briefly introduce some basic concepts, then a more detailed description of the main topic will follow.
