Abstract
PURPOSE OF REVIEW While guidelines exist for the evaluation and management of esophageal dysphagia in the general population, dysphagia disproportionately affects the elderly. In this article, we reviewed the literature on evaluating esophageal dysphagia in elderly patients and proposed a diagnostic algorithm based on this evidence. RECENT FINDINGS In older patients, dysphagia is often well compensated for by altered eating habits and physiologic changes, underreported by patients, and missed by healthcare providers. Once identified, dysphagia should be differentiated into oropharyngeal and esophageal dysphagia to guide diagnostic workup. For esophageal dysphagia, this review proposes starting with endoscopy with biopsies, given its relative safety even in older patients and potential for interventional therapy. If endoscopy shows a structural or mechanical cause, then further cross-sectional imaging should be considered to assess for extrinsic compression, and same session endoscopic dilation should be considered for strictures. If biopsies and endoscopy are normal, then esophageal dysmotility is more likely, and high-resolution manometry and additional workup should be performed following the updated Chicago Classification. Even after diagnosis of the root cause, complications including malnutrition and aspiration pneumonia should also be assessed and monitored, as they both result from and can further contribute to dysphagia. The successful evaluation of esophageal dysphagia in elderly patients requires a thorough, standardized approach to collecting a history, selection of appropriate diagnostic workup, and assessment of risk of potential complications, including malnutrition and aspiration.

Abstract
Achalasia, characterised by the absence of peristalsis and failure of relaxation of the lower oesophageal sphincter, is an uncommon degenerative condition that results in dysphagia. If left untreated it can lead to aspiration, oesophageal perforation, oesophagitis and malnutrition. It has a range of immune, allergic, viral and genetic aetiological causes. Successful diagnosis relies on the use of oesophagogastroduodenoscopy, barium swallow and oesophageal manometry to characterise the severity of the disease and to rule out underlying malignancy. Although no treatment can reverse the degenerative process, therapeutic strategies including lifestyle modification, medication, endoscopic and operative intervention can help to reduce symptoms. This article reviews the latest methods used to investigate and manage achalasia.

The Yield of Endoscopy and Histology in the Evaluation of Esophageal Dysphagia: Two Referral Centers’ Experiences. Medicina (B Aires) 2021; 57:medicina57121336. [PMID: 34946281 PMCID: PMC8705225 DOI: 10.3390/medicina57121336] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2021] [Revised: 11/25/2021] [Accepted: 12/02/2021] [Indexed: 11/16/2022] Open
Abstract
Background and Objectives: The initial diagnostic test required to evaluate esophageal dysphagia is upper endoscopy (EGD) to assess the structure of the esophagus and the esophageo-gastric junction (EGJ). Taking biopsies during EGD has become a common practice in patients with dysphagia to rule out eosinophilic esophagitis (EoE). The aims of this study were to evaluate the endoscopic findings of patients who underwent EGD for esophageal dysphagia, to assess the rate of biopsy taking from the esophagus to diagnose/exclude EoE, and to report histology outcomes of these biopsies. Materials and Methods: This was a retrospective multicenter study that included individuals ≥18 years who underwent EGD due to esophageal dysphagia between the years 2015 and2020, (with no other alarm signs, such as weight loss, new iron deficiency anemia, and lymphadenopathy). We obtained data from patients’ electronic files. The endoscopy and histology findings were obtained from endoscopy reports saved in our electronic files. Results: A total of 209 patients were included in the study. The average age was 57.1 ± 17.1 years. The most common endoscopic findings were normal endoscopy in 76 patients (36.4%) and erosive esophagitis in 75 patients (35.9%). Barrett’s esophagus and esophageal malignancy were encountered in 11 patients (5.3%) and 2 patients (0.95%), respectively. Esophageal biopsies were taken in 50.2% of patients, and one patient had histological evidence of EoE (0.5%). On univariate analysis, there was a trend for association between proton pump inhibitors (PPIs) use and a normal EGD, but it was not statistically significant (OR 0.28, 95% CI 0.07–1.11, p = 0.07). Conclusions: Endoscopic findings were prevalent in dysphagia patients even when no other alarm symptoms exist. Neoplastic lesions and EOE were rare in our study.

Association of eosinophil-mediated inflammatory biomarkers with the presence of the Schatzki ring. Adv Med Sci 2021; 66:279-283. [PMID: 34091432 DOI: 10.1016/j.advms.2021.05.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2020] [Revised: 02/23/2021] [Accepted: 05/25/2021] [Indexed: 11/15/2022]
Abstract
PURPOSE The study aimed to assess the level of inflammatory biomarkers related to eosinophilia: interleukins 5 (IL-5) and 13 (IL-13), eotaxin 3, major basic protein (MBP) and transforming growth factor β1 (TGF-β1) in patients with dysphagia and Schatzki ring (SR), as well as the characteristics of this group of patients in terms of the features differentiating gastroesophageal reflux disease (GERD) and eosinophilic esophagitis (EoE). PATIENTS AND METHODS We analyzed 42 patients with dysphagia, each of whom underwent panendoscopy with an assessment of the occurrence of SR, retrospectively assessed EoE Endoscopic Reference Score (EREFS) total, inflammatory and fibrostenotic and serum concentrations of IL-5 and 13, TGF-β1, eotaxin 3 and MBP. All of them completed a symptom and comorbid questionnaire. Patients diagnosed with SR constituted the SR group (n = 8), the rest - the non-SR group. The quantification of the biomarkers was performed by enzyme immunoassay (ELISA). In the data analysis, p ≤ 0.05 was considered statistically significant. RESULTS We demonstrated a significant increase in terms of exceeding the reference values of TGF-β1 (37.5% vs 8.8%) and MBP (75% vs 35.3%) in patients with SR compared to the non-SR group (qualitative analysis). There was also a statistically significant increase in the concentration of each of the determined biomarkers (quantitative analysis) in the SR group. CONCLUSIONS The increase in TGF-β1 and MBP concentrations indicates the inflammatory and probably fibrostenotic pathogenesis of SR. Obtained results do not allow for an unequivocal classification of SR as a complication typical only for GERD or EoE.

Abstract
Dysphagia is a common problem affecting all ages. It is increasing in frequency particularly among the younger population due to the rising incidence of eosinophilic oesophagitis, a condition which often leads to acute presentation to hospital for the first time with food bolus obstruction requiring endoscopic removal. Careful history taking remains the first and most important step in evaluating dysphagia, and it is especially important to distinguish an oropharyngeal versus oesophageal origin, which helps to guide further investigation and therapy. The three main investigations for dysphagia remain endoscopy, barium study and manometry, with endoscopy also offering therapeutic potential. Management is largely determined by the eventual diagnosis, often in a multi-disciplinary setting.

Abstract
Dysphagia, which is characterized by difficulty in oro-gastric bolus transit, is a common condition. It is broadly classified into oropharyngeal or esophageal pathology. A wide array of differentials for dysphagia and initial clinical suspicion of oropharyngeal or esophagus etiology can assist in further evaluation. Fiberoptic endoscopic evaluation of swallowing (FEES) and videofluoroscopic swallow study (VFSS) are the preferred modalities for assessing oropharyngeal bolus transit, residual, as well as determining the risk of laryngeal aspiration. High-resolution pharyngeal manometry (HRPM) is an emerging modality for optimal topographical and pressure assessment of pharyngeal anatomy. HRPM provides improved assistance in evaluating the strength of the pharyngeal muscular contraction. Esophagogastroduodenoscopy (EGD) is the preferred exam for patients with suspected esophageal etiology of dysphagia. Barium swallow provides luminal assessment and assists in evaluating esophageal motility; it is non-invasive, but therapeutic interventions like biopsy cannot be performed. High-resolution esophageal manometry (HREM) has added another dimension in the diagnosis of esophageal motility disorders. The purpose of this review article is to help internists and primary care providers get a better understanding of the role of various imaging modalities in diagnosing dysphagia in the elderly population. This article also provides a comprehensive review and detailed comparison of these imaging modalities based on the latest evidence.

Biopsy forceps disruption paired with bougie dilation of esophageal strictures lengthens time to repeat intervention. Dis Esophagus 2021; 34:6000364. [PMID: 33236096 DOI: 10.1093/dote/doaa113] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/18/2020] [Revised: 07/27/2020] [Accepted: 09/30/2020] [Indexed: 12/11/2022]
Abstract
Esophageal strictures commonly cause dysphagia and require treatment with endoscopic dilation using balloons or bougies. We aimed to determine whether biopsy forceps disruption of strictures at time of dilation increases time to repeat intervention or duration of intervention-free follow-up. We performed a retrospective analysis of 289 adults (age 61.0 ± 0.8 years, 66.4% female) who underwent dilation of an esophageal stricture at our tertiary care center between 2014 and 2016. Exclusions consisted of endoscopic intervention within the preceding 6 months, prior foregut neoplasia, achalasia, radiofrequency ablation, endoscopic mucosal resection, endoscopic submucosal dissection, or foregut surgery. Demographics, clinical presentation, dilation technique, and follow-up were abstracted from electronic medical records. We compared time to repeat dilation and duration of intervention-free follow-up between treatment subgroups. Balloon dilation was performed more often than bougie dilation (76.8 vs. 17.6%); biopsy forceps disruption was performed in 23.2%. Over a median follow-up of 52.9 months, 135 patients (46.7%) underwent repeat dilation. Age, body mass index, gender, and use of antisecretory medications did not influence need for repeat dilation (P = ns for each). Bougie dilation with biopsy forceps disruption prolonged time to repeat dilation in all patients (P ≤ 0.02), particularly in those with gastroesophageal reflux disease (P ≤ 0.03), compared with bougie dilation alone and balloon dilation with or without disruption. On Kaplan-Meier analysis, bougie dilation with biopsy forceps resulted in longer intervention-free follow-up compared with dilation alone (P = 0.03). We conclude that stricture disruption with biopsy forceps increases time to repeat intervention with bougie but not balloon dilation.

Abstract
Upper gastrointestinal (GI) endoscopies are performed for several reasons. The overuse of endoscopy has negative effects on the quality of healthcare and pressurises endoscopy services. It also results in the complications. These complications include pneumoperitoneum, pneumomediastinum and subcutaneous pneumomediastinum. However, it is worth noting that these complications rarely occur during endoscopy of the upper GI tract. These complications, when they occur, indicate perforation of the retroperitoneal space or peritoneal cavity. In this article, we discuss a case of pneumoperitoneum, pneumomediastinum and subcutaneous emphysema after upper GI endoscopy.

Abstract
Introduction Dysphagia is highly prevalent in patients with a history of recurrent acid peptic disease. Endoscopy is the mainstay of diagnostic workup of these patients to reach underlying cause and appropriate subsequent treatment. The objective of the study was to determine the frequency of various types of endoscopic findings in patients with dysphagia and the association of these findings with gender, age and duration of symptoms. Methods This cross-sectional study was carried out in the Department of Gastroenterology of a tertiary care hospital in Rawalpindi, Pakistan. A total of 137 patients who presented with a history of dysphagia for at least two weeks were enrolled in the study. Duration of symptoms was noted, and all patients underwent upper gastrointestinal endoscopy to find out the cause of dysphagia. Tissue biopsies were obtained, and further histopathological examination was performed to correlate the findings with symptoms of dysphagia. Results A total of 137 patients were enrolled for six months. The mean age of the patients was 56.9 ± 17.44 years, and the mean duration of symptoms was 15.96 ± 12.31 weeks. There were 65 (47.4%) males and 72 (52.6%) females in the study. Majority of them, 123 (89.8%), presented with a short duration of symptoms that varied between 2-24 weeks and were mainly middle-aged (31-60 years) and old-aged (61-80 years). The most commonly observed endoscopic findings were esophageal stricture in 25 (18.2%), achalasia cardia in 20 (14.6%), esophageal mass in 12 (8.8%) and reflux esophagitis in 7 (5%) patients. No association was seen between age, gender and duration of symptoms and findings on the endoscopy. Conclusion Dysphagia is associated with many endoscopic findings that are not related to demographic variables and must be evaluated earlier to reduce further morbidity and mortality.

Abstract
In this case, we describe a unique case of large renal hydronephrosis in a 79-year-old Indian male patient who had initially presented with 3 months of progressive dysphagia and loss of weight. His dysphagia was initially thought to be related to the atypical diagnosis of achalasia and was being considered for an elective laparoscopic Heller myotomy. On performing CT of the abdomen, a large renal mass was discovered. However, predicament remained regarding the exact aetiology of this renal mass. This case highlights a tremendously intriguing case of dysphagia with an underlying aetiology that has not been reported elsewhere previously.

Abstract
PURPOSE OF REVIEW This review presents an overview of the diagnostic approach to esophageal dysphagia and summarizes recent epidemiological trends and technical advancements. RECENT FINDINGS The evaluation of dysphagia begins with a detailed history followed by endoscopy to evaluate for any structural abnormalities including malignancy. This is especially true given the emergence of eosinophilic esophagitis (EoE) as a dominant cause of esophageal dysphagia. In fact, it is now standard practice to obtain esophageal biopsies during endoscopy performed to evaluate dysphagia, since EoE can present without the characteristic mucosal features of rings, furrows, and exudate. Achalasia is also more frequently encountered since the introduction of high-resolution manometry (HRM) and the Chicago Classification into clinical practice. The Chicago Classification provides a stepwise diagnostic algorithm for evaluating HRM studies and systematically diagnosing esophageal motility disorders. Lastly, the functional lumen imaging probe (FLIP) is a novel technology that has added insight into both achalasia and EoE. Measuring esophageal distensibility with FLIP has useful prognostic implications for both diseases, and FLIP can identify motility abnormalities in achalasics not detected with HRM. A careful history is key to the efficient evaluation of dysphagia, and endoscopy is usually the first diagnostic study to obtain. For patients with prominent reflux symptoms, an empiric trial with proton pump inhibitors is reasonable then because reflux disease is such a common cause of dysphagia. Thereafter, patients should undergo HRM to evaluate for a motility disorder, and FLIP can provide complementary data to guide management.

Abstract
Evaluation of dysphagia typically starts with esophagogastroduodenoscopy (EGD); further testing is pursued if this is negative. When no mucosal, structural, or motor esophageal disorders are identified with persisting symptoms, functional dysphagia is considered. We evaluated outcomes in patients undergoing EGD for dysphagia, and estimated prevalence of functional dysphagia. The endoscopy database at single tertiary care center was interrogated to identify EGDs performed for an indication of 'dysphagia' over a 12-month period (2008-09). Electronic medical records were reviewed over the next 8 years to assess if an etiology was identified. Data were analyzed to assess the diagnostic yield of endoscopy and subsequent tests in the evaluation of dysphagia. Of 5486 EGDs, 822 (15.0%) were performed for dysphagia in 694 patients (58.4 ± 0.6 year, range: 18-95 year, 55.8% female). Of these, 529 (76.2%) had EGD findings that explained dysphagia; another 22 (3.2%) had findings on histopathology. Of the remainder 143 patients (20.6%) with normal index EGD, 38 (26.6%) patients underwent barium esophagram with 15 (39.5%) having abnormal studies. 19 patients (13.3%) underwent esophageal high resolution manometry with 12 (63.2%) being abnormal, and 7 had a mechanism for dysphagia on alternate testing. A repeat EGD was abnormal in 6 patients, while 45 patients were lost to follow-up. 42 patients had complete resolution of symptoms despite normal endoscopy, of which 30 were treated empirically with a proton pump inhibitor (PPI). Only 16 patients had no findings on evaluation, and had continued dysphagia symptoms, representing true functional dysphagia in 2.3% of all dysphagia patients and 11.2% of patients with normal EGD. Endoscopy remains the test with the highest yield (over 75%) for a diagnosis in patients presenting with dysphagia; secondary tests are useful when endoscopy does not provide a diagnosis. Benign strictures and GERD-related etiologies are leading causes; PPI therapy is useful even when testing is negative. Functional dysphagia is extremely rare, accounting for <2.5% of all dysphagia.

Abstract
BACKGROUND Eosinophilic esophagitis (EoE) is a chronic esophageal inflammation that may lead to stricture formation. This narrowing can cause major complications including food impactions. Despite increasing interest in EoE accurate data on its natural course is scarce. Therefore, we aimed to investigate the natural course of EoE and to evaluate the association between undiagnosed disease and the occurrence of complications over two decades in a large cohort. METHODS We retrospectively analyzed charts of patients diagnosed with EoE between 1996 and 2015, collected from 15 hospitals throughout the Netherlands. Histologic, clinical, and endoscopic characteristics were identified and stratified by age and diagnostic delay. RESULTS We included 721 patients (524 males, 117 children (≤18 years)). Dysphagia and food impactions were more common in adults whereas children more often presented with vomiting and abdominal pain (all p < 0.001). The prevalence of fibrotic endoscopic features was higher in adults (76%) than in children (39%) (p < 0.001). As time with undiagnosed disease progressed the percentage of patients with strictures and food impactions increased from 19% and 24% (diagnostic delay ≤ 2 years) to 52% and 57% (diagnostic delay ≥ 21 years) (p < 0.001), respectively. In a multivariate logistic regression model, diagnostic delay (odds ratio (OR) = 1.09; 95% confidence interval (CI) = 1.05-1.13) and male gender (OR = 2.69, 95% CI = 1.61-4.50) were the major risk factors for stricture presence. CONCLUSION During the natural course of EoE, progression from an inflammatory to a fibrostenotic phenotype occurs. With each additional year of undiagnosed EoE the risk of stricture presence increases with 9%.

Abstract
BACKGROUND AND AIMS Our aim is to review the literature and provide guidelines for the assessment of uninvestigated dysphagia. METHODS A systematic literature search identified studies on dysphagia. The quality of evidence and strength of recommendations were rated according to the Grading of Recommendation Assessment, Development, and Evaluation (GRADE) approach. Statements were discussed and revised via small group meetings, teleconferences, and a web-based platform until consensus was reached by the full group. RESULTS The consensus includes 13 statements focused on the role of strategies for the assessment of esophageal dysphagia. In patients presenting with dysphagia, oropharyngeal dysphagia should be identified promptly because of the risk of aspiration. For patients with esophageal dysphagia, history can be used to help differentiate structural from motility disorders and to elicit alarm features. An empiric trial of proton pump inhibitor therapy should be limited to four weeks in patients with esophageal dysphagia who have reflux symptoms and no additional alarm features. For patients with persistent dysphagia, endoscopy, including esophageal biopsy, was recommended over barium esophagram for the assessment of structural and mucosal esophageal disease. Barium esophagram may be useful when the availability of endoscopy is limited. Esophageal manometry was recommended for diagnosis of esophageal motility disorders, and high-resolution was recommended over conventional manometry. CONCLUSIONS Once oropharyngeal dysphagia is ruled out, patients with symptoms of esophageal dysphagia should be assessed by history and physical examination, followed by endoscopy to identify structural and inflammatory lesions. If these are ruled out, then manometry is recommended for the diagnosis of esophageal dysmotility.

Abstract
Objectives To compare videofluoroscopy that included a tablet test with impedance planimetry (EndoFLIP®) for the evaluation of oesophageal stenosis in patients with dysphagia. Methods In 56 patients, videofluoroscopic examinations following the transit of a 14-mm tablet were retrospectively reviewed and correlated with impedance planimetry findings, a catheter-based method using impedance planimetry to display the oesophageal diameter estimates. Additional findings assessed were the occurrence of symptoms during tablet passage and evaluation of oesophageal motility. Results Impaction of the tablet occurred in 31/56 patients; nine showed a moderate delay (2–15 s), three a short delay (<2 s) and 13 no delay of tablet passage. Both methods showed a significant correlation between tablet impaction and oesophageal diameter <15.1 mm, as measured by impedance planimetry (p = 0.035). The feeling of the tablet getting stuck was reported by seven patients, six showing impaction of the tablet (four with an EndoFLIP-diameter < 13 mm, two with a diameter of 13–19 mm) and one showing delayed passage (EndoFLIP diameter of 17 mm). Conclusions Videofluoroscopy and impedance planimetry correlate significantly regarding tablet impaction and residual oesophageal lumen. A standardized 14-mm tablet is helpful in demonstrating oesophageal strictures in dysphagic patients. Triggering of subjective symptoms provides valuable information during a videofluoroscopic study. Key Points • A 14-mm tablet can demonstrate oesophagogastric junction narrowing in patients with dysphagia. • Type of passage of a tablet enables estimation of oesophageal luminal diameter. • Videofluoroscopy and impedance planimetry correlate significantly regarding tablet impaction and residual oesophageal lumen.

Abstract
BACKGROUND AND AIMS Schatzki rings are found in the distal esophagus, are associated with hiatal hernias, and present with intermittent dysphagia to solid foods. They can be identified by radiology (GI series or barium swallow studies) or endoscopy. Rings are not always visualized during endoscopy in patients in whom they are suspected clinically. The Bolster technique involves application of epigastric abdominal pressure, which offers the potential to reveal a Schatzki ring that is otherwise obscured within a reduced hiatal hernia. The aim of this study was to determine whether the Bolster technique improves endoscopic detection of Schatzki rings. METHODS We reviewed 30 symptomatic patients with a history of a Schatzki ring in a tertiary care center. The Bolster technique was applied to patients in whom the ring was not visible during standard endoscopy. The main outcome measurement was identification of the Schatzki ring after the Bolster technique. RESULTS A Schatzki ring was visible during standard endoscopy in 26 of the 30 patients. In the remaining 4, the ring was visible only after the application of the Bolster technique. CONCLUSION The Bolster technique is a simple maneuver that can increase detection rates of Schatzki rings during endoscopy.

Electroencephalography (EEG) systems can enable us to study cerebral activation patterns during performance of swallowing tasks and possibly infer about the nature of abnormal neurological conditions causing swallowing difficulties. While it is well known that EEG signals are non-stationary, there are still open questions regarding the stationarity of EEG during swallowing activities and how the EEG stationarity is affected by different viscosities of the fluids that are swallowed by subjects during these swallowing activities. In the present study, we investigated the EEG signal collected during swallowing tasks by collecting data from 55 healthy adults (ages 18-65). Each task involved the deliberate swallowing of boluses of fluids of different viscosities. Using time-frequency tests with surrogates, we showed that the EEG during swallowing tasks could be considered non-stationary. Furthermore, the statistical tests and linear regression showed that the parameters of fluid viscosity, sex, and different brain regions significantly influenced the index of non-stationarity values. Therefore, these parameters should be considered in future investigations which use EEG during swallowing activities.

Meta-analysis: the safety and efficacy of dilation in eosinophilic oesophagitis. Aliment Pharmacol Ther 2013; 38:713-20. [PMID: 23915046 DOI: 10.1111/apt.12438] [Citation(s) in RCA: 57] [Impact Index Per Article: 5.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/26/2013] [Revised: 06/03/2013] [Accepted: 07/10/2013] [Indexed: 12/13/2022]
Abstract
BACKGROUND Oesophageal dilation is one of the most effective options in the management of symptoms of eosinophilic oesophagitis (EoE). However, earlier reports described an increased rate of complications. AIM To perform a meta-analysis of population-based studies of the risks associated with dilation and the clinical efficacy and duration of response to dilation in EoE. METHODS Using MEDLINE and EMBASE, a systematic search was performed for published articles since 1977 describing cohort or randomised controlled trials of dilation in EoE. Summary estimates, including 95% confidence interval (CI), were calculated for the occurrence of complications associated with dilations (perforations, haemorrhage, chest pain, lacerations) and percentage of patients with symptom improvement following dilation. Heterogeneity was calculated using the I² statistic. RESULTS The search resulted in 232 references, of which 9 studies were included in the final analysis. The studies described 860 EoE patients, of whom 525 patients underwent at least one oesophageal dilation and a total of 992 dilations. There were three cases of perforation (95% CI 0-0.9%, I² 0%) and one haemorrhage (95% CI 0-0.8%, I² 0%). Six studies reported postprocedural chest pain in 2% of cases (95% CI 1-3, I² 53%). Clinical improvement from dilation occurred in 75% of patients (95% CI 58-93%, I² 86%). CONCLUSIONS Dilation in patients with eosinophilic oesophagitis is a safe procedure with a low rate of serious complications (<1%), and seems to result in at least a short-term improvement of symptoms in the majority of patients.
