[PMID: 37198410 DOI: 10.1007/s00464-023-10129-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2023] [Accepted: 05/08/2023] [Indexed: 05/19/2023]
Abstract
BACKGROUND Controlled radial expansion (CRE) balloon dilators are traditionally used to dilate esophageal strictures during an esophagogastroduodenoscopy (EGD). EndoFLIP is a diagnostic tool used during an EGD to measure important parameters of the gastrointestinal lumen, capable of assessing treatment before and after dilation. EsoFLIP is a related device that combines a balloon dilator with high-resolution impedance planimetry to provide some of the luminal parameters in real time during dilation. We sought to compare procedure time, fluoroscopy time, and safety profile of esophageal dilation using either CRE balloon dilation combined with EndoFLIP (E + CRE) versus EsoFLIP alone. METHODS A single-center retrospective review was performed to identify patients ≤ 21 years of age who underwent an EGD with biopsy and esophageal stricture dilation using E + CRE or EsoFLIP between October 2017 and May 2022. RESULTS Twenty-nine EGDs with esophageal stricture dilation were performed in 23 patients (19 E + CRE and 10 EsoFLIP). The two groups did not differ in age, gender, race, chief complaint, type of esophageal stricture, or history of prior gastrointestinal procedures (all p > 0.05). The most common medical history in the E + CRE and EsoFLIP groups were eosinophilic esophagitis and epidermolysis bullosa, respectively. Median procedures times were shorter in the EsoFLIP cohort compared to E + CRE balloon dilation (40.5 min [IQR 23-57 min] for the EsoFLIP group; 64 min [IQR 51-77 min] for the E + CRE group; p < 0.01). Median fluoroscopy times were also shorter for patients who underwent EsoFLIP (0.16 min [IQR 0-0.30 min] for EsoFLIP dilation; 0.30 min [IQR 0.23-0.55] for the E + CRE group; p = 0.003). There were no complications or unplanned hospitalizations in either group. CONCLUSION EsoFLIP dilation of esophageal strictures was faster and required less fluoroscopy than CRE balloon dilation combined with EndoFLIP in children, while being equally as safe. Prospective studies are needed to further compare the two modalities.

Abstract
Swallowing impairment is a highly prevalent and clinically significant problem affecting people and dogs. There are myriad causes of swallowing impairment of which gastroesophageal reflux is the most common in both species. Similarities in anatomy and physiology between humans and canines results in analogous swallowing disorders including cricopharyngeus muscle achalasia, esophageal achalasia, hiatal herniation, and gastroesophageal reflux with secondary esophagitis and esophageal dysmotility. Accordingly, the diagnostic approach to human and canine patients with swallowing impairment is similar. Diagnostic procedures such as swallowing fluoroscopy, high-resolution manometry, pH/impedance monitoring, and endolumenal functional luminal imaging probe can be performed in both species; however, nasofacial conformation, increased esophageal length, and the difficulty of completing several of these procedures in awake dogs are inherent challenges that need to be considered. Human patients can convey their symptoms and respond to verbal cues, whereas veterinarians must rely on clinical histories narrated by pet owners followed by comprehensive physical examination and observation of the animal eating different food consistencies and drinking water. Dogs may also be unwilling to drink or eat in the hospital setting and may be resistant to physical restraint during diagnostic procedures. Despite the species differences and diagnostic challenges, dogs are a natural animal model for many oropharyngeal and esophageal disorders affecting people, which presents a tremendous opportunity for shared learnings. This manuscript reviews the comparative aspects of esophageal anatomy and physiology between humans and canines, summarizes the diagnostic assessment of swallowing impairment in both species, and discusses future considerations for collaborative medicine and translational research.

Abstract
BACKGROUND Gastroesophageal reflux disease (GERD) is a common digestive complaint that can negatively affect patients' quality of life and have serious complications if inadequately treated. LOCAL PROBLEM Facilitating prompt and efficient access to digestive care is imperative especially given the current burden of gastrointestinal diseases such as GERD. METHODS A clinical team conducted a quality improvement study in which a nurse practitioner (NP) navigator performed a preconsultation chart review for patients with refractory GERD referred to an Esophagus Center between August and December 2018. INTERVENTIONS Based on preconsultation chart review, the NP navigator arranged for diagnostic testing and follow-up. Days from consultation to testing completion and establishment of plan were tracked and compared with historic controls. The NP navigator documented time spent for chart review and care coordination. RESULTS The median number of days from consultation to testing completion for patients who underwent NP navigation and required diagnostic testing (n = 26) was 33.5 as compared with 64.5 for historic controls who required testing but received usual care (n = 28) (p = .005). The median number of days from consultation to establishment of a management plan was 52 for patients who underwent NP navigation as compared with 97 for historic controls who did not (p = .005). The mean amount of time spent by the NP navigator for chart review and care coordination was 17.5 min (n = 30). CONCLUSIONS Incorporation of NP navigators into gastroenterology practices offers a potential solution for timelier patient care delivery.

Abstract
The functional lumen imaging probe (FLIP) is a diagnostic tool that utilizes impedance planimetry to allow the assessment of luminal diameter and distensibility. It has been used primarily in esophageal diseases, in particular, in the assessment of achalasia, esophagogastric junction outflow obstruction, and eosinophilic esophagitis (EoE). The usage and publications have increased over the past decade and it is now an essential tool in the armamentarium of the esophagologist. Indications are emerging outside of the esophagus, in particular with regard to gastroparesis. Our paper will review the history of FLIP, optimal current usage, data for key esophageal disorders (including achalasia, reflux, and EoE), data for nonesophageal disorders, and our sense as to whether FLIP is ready for prime time, as well as gaps in evidence and suggestions for future research.

Abstract
Impedance has traditionally been employed in esophageal disease as a means to assess bolus flow and reflux episodes. Recent and ongoing research has provided new and novel applications for this technology. Measurement of esophageal mucosal impedance, via either multichannel intraluminal impedance catheters or specially designed endoscopically deployed impedance catheters, provides a marker of mucosal integrity. Mucosal impedance has been shown to segregate gastroesophageal reflux disease (GERD) and eosinophilic esophagitis from non-GERD controls and may play a role in predicting response to reflux intervention. More data are needed with regard to other esophageal subgroups, outcome studies, and functional disease. Our paper reviews the history of impedance in esophageal disease, the means of assessing baseline and mucosal impedance, data with regard to the newly developed mucosal impedance probes, the clinical utility of mucosal impedance in specific clinical conditions, and limitations in our existing knowledge, along with suggestions for future studies.

Abstract
Eosinophilic esophagitis (EoE) is a chronic, allergen-driven, immune mediated disease of the esophagus that progresses to esophageal fibrostenosis if not well treated. The aim of this review is to provide an update on recent clinical advances in the development of diagnostic and therapeutic approaches for EoE. At present, the diagnosis and disease monitoring for EoE rely on repetitive endoscopic evaluations and esophageal tissue acquisition for histopathologic analysis. Recent advancements in EoE diagnosis include transnasal endoscopy, endoscopic functional lumen imaging probe, and the emergence of non-invasive diagnostic tools including cytosponge, esophageal string test, and mucosal impedance probe. Biomarkers for EoE have not yet proven their clinical utility. The current treatment modalities for EoE are topical corticosteroid, proton-pump inhibitors, elimination diet, and dilation. Promising results from clinical trials are emerging for biologic agents that target the interleukin (IL)-13 and the IL-4/IL-13 receptor, specifically, RPC4046 and dupilumab. Especially, dupilumab is promising to become the orphan drug of EoE.

Abstract
BACKGROUND AND AIMS Idiopathic Esophago-gastric outflow obstruction (EGJOO) is a new clinical entity resulting in delayed esophageal emptying secondary to a poorly relaxing lower esophageal sphincter. Little is known about treatment outcomes of idiopathic EGJOO patients. The aim of this study was to investigate the clinical response of pneumatic dilation (PD) in idiopathic EGJOO patients with a standing barium column and/or with pill arrest on timed barium esophagram (TBE) before and after undergoing PD. METHODS Idiopathic EGJOO patients with retained liquid barium on TBE at 1 minute and/or with pill arrest in esophagus at 5 minutes were included. Patients were treated with PD and evaluated with post-procedural TBE. RESULTS A total of 33 patients with Idiopathic EGJOO and poor esophageal emptying on TBE were treated with PD. 67% of Idiopathic EGJOO patients reported subjective symptom relief, 18% improved and symptoms later recurred, 6% were lost to follow up, and 9% reported no change. TBE results of pre-PD showed 1 minute average barium column height of 11.0 cm and 1 minute barium column width of 1.7 cm. There was significant decrease in 1 minute liquid barium column height and width (P < 0.001 and <0.001, respectively) as well as significant improvement in pill passing (P < 0.006) after undergoing PD. No complications occurred after PD. CONCLUSION PD is an effective initial treatment for Idiopathic EGJOO patients with abnormal TBE. Pneumatic dilation relieved symptoms and improved esophageal emptying in Idiopathic EGJOO patients on TBE.

Abstract
Systemic sclerosis (SSc) is a multisystem connective tissue disease, characterized by chronic inflammation and vascular changes that result in esophageal smooth muscle atrophy and fibrosis. Subsequent progressive loss of peristalsis in the distal esophagus and loss of lower esophageal sphincter function lead to problems with the protective barrier and exposure of sensitive tissues to the gastroduodenal contents, a disorder called reflux disease. Areas covered: Depending on the range, nature and symptoms of the disease, the term 'reflux disease' may refer to gastroesophageal reflux, laryngopharyngeal reflux, microaspiration into the airways and silent reflux. Despite the links between these visceral complications, this connection remains controversial. This is due to a lack of complete understanding, the asymptomatic nature of the disease and the limited diagnostic accuracy of tests, which can delay diagnosis. Such delays are problematic, given that the early detection of GERD in SSc patients, the timing of assessment, the treatment of the organs involved are critical aspects of patient prognosis and disease outcome. Expert commentary: This review summarizes the most recent knowledge about the pathophysiology, diagnosis and prospective treatment of GERD in SSc patients and highlights how innovative technologies applied through an integrative, interdisciplinary approach may soon lead to effective treatment strategies.

Abstract
The prevalence of gastroesophageal reflux disease (GERD) is increasing in Korea, and physicians, including surgeons, have been focusing on its treatment. Indeed, in Korea, medical treatment using a proton pump inhibitor is the mainstream treatment for GERD, while awareness of surgical treatment is limited. Accordingly, to promote the understanding of surgical treatment for GERD, the Korean Anti-Reflux Surgery Study Group published the Evidence-Based Practice Guideline for the Surgical Treatment of GERD. The guideline consists of 2 sections: fundamental information such as the definition, symptoms, and diagnostic tools of GERD and a recommendation statement about its surgical treatment. The recommendations presented 5 debates regarding fundoplication: 1) comparison of the effectiveness of medical and surgical treatments, 2) effectiveness of surgical treatment in cases of refractory GERD, 3) effectiveness of surgical treatment of extraesophageal symptoms, 4) comparison of effectiveness between total and partial fundoplication, and 5) effectiveness of fundoplication in cases of hiatal hernia. The present guideline is the first to demonstrate the efficacy of the surgical treatment GERD in Korea.

Abstract
PURPOSE OF REVIEW This review addresses the similarities and differences between the spastic esophageal disorders, including jackhammer esophagus, distal esophageal spasm (DES), and type III (spastic) achalasia. The pathophysiology, diagnosis, and treatment of each separate disorder are discussed herein, with an emphasis on overlapping and discordant features. RECENT FINDINGS The Chicago Classification is a hierarchical organizational scheme for esophageal motility disorders, currently in its third iteration, with direct impact on the definitions of these three disorders. Complementary diagnostic tools such as impedance planimetry and novel manometric parameters continue to evolve. The suite of potential treatments for these disorders is also expanding, with progressive interest in the role of peroral endoscopic myotomy alongside established pharmacologic and mechanical interventions. Although jackhammer esophagus, distal esophageal spasm, and type III achalasia frequently overlap in terms of their clinical presentation and available management approaches, the divergences in their respective diagnostic criteria suggest that additional study may reveal additional mechanistic distinctions that lead in turn to further refinements in therapeutic decision-making.

Abstract
PURPOSE OF REVIEW For patients with eosinophilic esophagitis (EoE), endoscopic dilation has been used primarily to provide immediate symptomatic relief of dysphagia. This report reviews the current position of esophageal dilation in the therapeutic algorithm for EoE, including effectiveness and safety issues. RECENT FINDINGS Esophageal strictures in EoE develop as a consequence of long-lasting esophageal eosinophilia, with patient age and diagnostic delay as well established risk factors. Endoscopic dilation leads to immediate symptomatic improvement in 95% of EoE patients who have strictures or narrow caliber esophagus. As dilation has no effect on the underlying eosinophil inflammation, repeated procedures are usually needed to maintain symptoms in remission. Adding an effective drug or dietary-based EoE therapy reduces the need of further dilation. The high rate of severe complications from dilation reported in early literature has not been reproduced in most recent series, with mild postprocedural chest pain as the most common side effect. Current data suggest that the risk of esophageal perforation is less than 1%. Mucosal tears after dilation should no longer be considered a complication, but rather a marker of procedural success. SUMMARY Esophageal dilation should be considered in EoE patients with esophageal strictures or narrow caliber esophagus who have persistent dysphagia/food impaction despite an effective anti-inflammatory treatment.

Abstract
An integrated esophageal center (IEC) is a multidisciplinary team with expertise, skill, range, and facilities necessary to achieve optimal outcomes in patients with esophageal diseases efficiently and expeditiously. Within IEC, patients presenting with esophageal symptoms undergo a detailed clinical, functional and structural evaluation of their esophagus prior to implementation of tailored medical, endoscopic or surgical therapy. Serving as a core, the IEC clinical practice also supports research and innovation in esophageal diseases as well as public and physician education. Referrals to the unit may be primary, either from primary care or self-initiated, or secondary from other specialty practices, to reassess patients who have previously failed therapies and to manage complex or complicated cases. The fundamental goals of the IEC are to provide value for patients with esophageal diseases, streamlining complex diagnostic investigations and expediting therapies aiming at reducing costs while improving clinical outcomes, and to accelerate knowledge generation through robust interaction and cross-training across disciplines. The organization of the IEC goes beyond traditional academic and clinical silos and involves a director and administrative team coordinating faculty and fellows from both medical and surgical disciplines and supported by other clinical lines, such as radiology, pathology, etc., while it interfaces with physicians, the public, basic, translational and clinical research groups, and related industry partners.
