Abstract
Duodenal polyps are found in 0.1 % to 0.8 % of all upper endoscopies. Duodenal adenomas account for 10 % to 20 % of these lesions. They can be sporadic or occur in the setting of a hereditary predisposition syndrome, mainly familial adenomatous polyposis. Endoscopy is the cornerstone of management of duodenal adenomas, allowing for diagnosis and treatment, primarily by endoscopic mucosal resection. The endoscopic treatment of duodenal adenomas has a high morbidity, reaching 15 % in a prospective study, consisting of bleeding and perforations, and should therefore be performed in expert centers. The local recurrence rate ranges from 9 % to 37 %, and is maximal for piecemeal resections of lesions > 20 mm. Surgical resection of the duodenum is flawed with major morbidity and considered a rescue procedure in cases of endoscopic treatment failures or severe endoscopic complications such as duodenal perforations. In this paper, we review the existing evidence on endoscopic diagnosis and treatment of non-ampullary duodenal adenomas.

Near-focus narrow-band imaging classification of villous atrophy in suspected celiac disease: development and international validation. Gastrointest Endosc 2021; 94:1071-1081. [PMID: 34228981 DOI: 10.1016/j.gie.2021.06.031] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/21/2021] [Accepted: 06/25/2021] [Indexed: 12/11/2022]
Abstract
BACKGROUND AND AIMS There are no agreed-on endoscopic signs for the diagnosis of villous atrophy (VA) in celiac disease (CD), necessitating biopsy sampling for diagnosis. Here we evaluated the role of near-focus narrow-band imaging (NF-NBI) for the assessment of villous architecture in suspected CD with the development and further validation of a novel NF-NBI classification. METHODS Patients with a clinical indication for duodenal biopsy sampling were prospectively recruited. Six paired NF white-light endoscopy (NF-WLE) and NF-NBI images with matched duodenal biopsy sampling including the bulb were obtained from each patient. Histopathology grading used the Marsh-Oberhuber classification. A modified Delphi process was performed on 498 images and video recordings by 3 endoscopists to define NF-NBI classifiers, resulting in a 3-descriptor classification: villous shape, vascularity, and crypt phenotype. Thirteen blinded endoscopists (5 expert, 8 nonexpert) then undertook a short training module on the proposed classification and evaluated paired NF-WLE-NF-NBI images. RESULTS One hundred consecutive patients were enrolled (97 completed the study; 66 women; mean age, 51.2 ± 17.3 years). Thirteen endoscopists evaluated 50 paired NF-WLE and NF-NBI images each (24 biopsy-proven VAs). Interobserver agreement among all validators for the diagnosis of villous morphology using the NF-NBI classification was substantial (κ = .71) and moderate (κ = .46) with NF-WLE. Substantial agreement was observed between all 3 NF-NBI classification descriptors and histology (weighted κ = 0.72-.75) compared with NF-WLE to histology (κ = .34). A higher degree of confidence using NF-NBI was observed when assessing the duodenal bulb. CONCLUSIONS We developed and validated a novel NF-NBI classification to reliably diagnose VA in suspected CD. There was utility for expert and nonexpert endoscopists alike, using readily available equipment and requiring minimal training. (Clinical trial registration number: NCT04349904.).

Abstract
Though superficial non-ampullary duodenal epithelial tumors (SNADETs) have been traditionally considered rare, there is a growing detection under the development and widespread of endoscopic techniques in recent times. Many case studies have revealed early manifestations of lesions through advanced endoscopic technology, however, because of the low incidence of duodenal tumors and challenges in diagnosing, the preoperative diagnosis criteria have not been established so far. In spite of this, recently the increasing detection rate of early duodenal epithelial lesions enhances the demand for minimally invasive treatment as well. The most suitable therapeutic endoscopic modality to remove duodenal lesions should be selected according to the size, location and histological invasive depth of duodenal lesions. Nevertheless, due to the special anatomical structure of the duodenum, the incidence of complications is much higher than in any other part of the digestive tract. To prevent these adverse events prophylactically, a few novel strategies have been applied effectively after resection. This review describes the current status of preoperative endoscopic diagnosis and endoscopic resection approaches, as well as countermeasures for avoiding procedure-related complications.

Abstract
1: ESGE recommends that all duodenal adenomas should be considered for endoscopic resection as progression to invasive carcinoma is highly likely.Strong recommendation, low quality evidence. 2: ESGE recommends performance of a colonoscopy, if that has not yet been done, in cases of duodenal adenoma.Strong recommendation, low quality evidence. 3: ESGE recommends the use of the cap-assisted method when the location of the minor and/or major papilla and their relationship to a duodenal adenoma is not clearly established during forward-viewing endoscopy.Strong recommendation, moderate quality evidence. 4: ESGE recommends the routine use of a side-viewing endoscope when a laterally spreading adenoma with extension to the minor and/or major papilla is suspected.Strong recommendation, low quality evidence. 5: ESGE suggests cold snare polypectomy for small (< 6 mm in size) nonmalignant duodenal adenomas.Weak recommendation, low quality evidence. 6: ESGE recommends endoscopic mucosal resection (EMR) as the first-line endoscopic resection technique for nonmalignant large nonampullary duodenal adenomas.Strong recommendation, moderate quality evidence. 7: ESGE recommends that endoscopic submucosal dissection (ESD) for duodenal adenomas is an effective resection technique only in expert hands.Strong recommendation, low quality evidence. 8: ESGE recommends using techniques that minimize adverse events such as immediate or delayed bleeding or perforation. These may include piecemeal resection, defect closure techniques, noncontact hemostasis, and other emerging techniques, and these should be considered on a case-by-case basis.Strong recommendation, low quality evidence. 9: ESGE recommends endoscopic surveillance 3 months after the index treatment. In cases of no recurrence, a further follow-up endoscopy should be done 1 year later. Thereafter, surveillance intervals should be adapted to the lesion site, en bloc resection status, and initial histological result. Strong recommendation, low quality evidence.

Abstract
BACKGROUND AND AIMS Lynch syndrome (LS) is associated with an increased risk of small bowel tumors but routine screening is not recommended in international guidelines. The aim of our study was to determinate the prevalence of duodenal tumors in a French cohort of LS patients. METHODS Patients carrying a germline pathogenic variant in a MMR gene, supported by our local network, in which at least one upper endoscopy had been performed, were included. We registered the occurrence of duodenal lesions in those patients. RESULTS 154 LS patients were identified including respectively 85 MSH2 and 41 MLH1 mutated patients respectively. Seven out of 154 (4.5%) had at least one duodenal lesion. Median age at diagnosis was 58 years (range: 49-73). The twelve lesions locations were: descending duodenum (n = 7), genu inferius (n = 2), duodenal bulb (n = 1), ampulla (n = 1), fourth duodenum (n = 1). Three lesions were invasive adenocarcinomas. The incidence rate of duodenal lesions in patients with MSH2 or MLH1 pathogenic variants was respectively 7.1% (6 out of 85) and 2.4% (1 out of 41) emphasizing a trend toward increased risk of developing duodenal lesion in MSH2 mutated patients: OR: 5.17, IC95% (0.8-60.07), p = 0.1307. CONCLUSION Regarding this high prevalence rate, especially in MSH2 patients, regular duodenal screening during upper endoscopy should be considered in routine in LS patients.

Abstract
Duodenal adenomas are the most common type of polyp arising from the duodenum. These adenomas can occur within and outside of genetic syndromes, and are broadly classified as non-ampullary or ampullary depending on their location. All adenomas have malignant potential and are therefore appropriately treated by endoscopic resection. However, the unique anatomical properties of the duodenum, namely its relatively thin and vascular walls, narrow luminal diameter and relationship to the ampulla and its associated pancreatic and biliary drainage, pose an increased degree of complexity for any endoscopic interventions in this area. This review will discuss the epidemiology of duodenal adenomas, their endoscopic detection and diagnosis, and techniques for safe and effective endoscopic resection of ampullary and non-ampullary lesions.

Abstract
BACKGROUND AND AIMS Celiac disease remains underdiagnosed at endoscopy. We aimed to assess the utility of I-Scan (virtual chromo-endoscopy) to improve sensitivity of endoscopy to detect markers of villous atrophy in this condition. METHODS Patients from 2 UK hospitals were studied in 3 groups. Group 1: standard high definition, white light endoscopy (WLE); Group 2: WLE plus I-Scan; Group 3: non-high definition control group. The presence of endoscopic markers was recorded. At least 4 duodenal biopsies were taken from all patients. Serology was performed concurrently and observations were compared with histology. RESULTS 758 patients (62% female, mean age 52) were recruited (Group 1: 230; Group 2: 228; Group 3: 300). 135 (17.8%) new diagnoses of coeliac disease were made (21 Group 1; 24 Group 2; 89 Group 3). The sensitivity for detection of endoscopic markers of villous atrophy was significantly higher in both Group 1 (85.7%, p=0.0004) and Group 2 (75%, p=0.005) compared to non-high definition controls (41.6%). There was no significant difference between high definition only and I-Scan groups (p=0.47). In non-high definition endoscopy a missed diagnosis was associated with lesser degrees of villous atrophy (p=0.019) and low tTG titre (p=0.007). CONCLUSIONS High definition endoscopy with or without I-Scan increases the detection of celiac disease during routine endoscopy.

Abstract
Nonampullary duodenal adenomas are relatively common in familial adenomatous polyposis (FAP), but nonampullary sporadic duodenal adenomas (SDAs) are rare. Emerging evidence shows that duodenal adenomas, regardless of their anatomic location and whether they are sporadic or FAP-related, share morphologic and molecular features with colorectal adenomas. The available data suggest that duodenal adenomas develop to duodenal adenocarcinomas via similar mechanisms. The optimal approach for management of duodenal adenomas remains to be determined. The techniques for endoscopic resection of duodenal adenoma include snare polypectomy, endoscopic mucosal resection (EMR), endoscopic submucosal dissection (ESD), and argon plasma coagulation ablation. EMR may facilitate removal of large duodenal polyps. Although several studies have reported cases of successful ESD for duodenal adenomas, the procedure is technically difficult to perform safely because of the anatomical properties of the duodenum. Although current clinical practice recommends endoscopic resection of all large duodenal adenomas in patients with FAP, endoscopic treatment is usually insufficient to guarantee a polyp-free duodenum. Surgery is indicated for FAP patients with severe polyposis or nonampullary SDAs or FAP-related polyps not amenable to endoscopic resection. Further studies are needed to develop newer endoscopic techniques to guide diagnostic and therapeutic decisions for future management of nonampullary duodenal adenomas.

Abstract
Superficial non-ampullary duodenal epithelial tumor (SNADET) is defined as a sporadic tumor that is confined to the mucosa or submucosa that does not arise from Vater's papilla, and it includes adenoma and adenocarcinoma. Recent developments in endoscopic technology, such as high-resolution endoscopy and image-enhanced endoscopy, may increase the chances of detecting SNADET lesions. However, because SNADET is rare, little is known about its preoperative endoscopic diagnosis. The use of endoscopic resection for SNADET, which has no risk of metastasis, is increasing, but the incidence of complications, such as perforation, is significantly higher than in any other part of the digestive tract. A preoperative diagnosis is required to distinguish between lesions that should be followed up and those that require treatment. Retrospective studies have revealed certain endoscopic findings that suggest malignancy. In recent years, several new imaging modalities have been developed and explored for real-time diagnosis of these lesion types. Establishing an endoscopic diagnostic tool to differentiate between adenoma and adenocarcinoma in SNADET lesions is required to select the most appropriate treatment. This review describes the current state of knowledge about preoperative endoscopic diagnosis of SNADETs, such as duodenal adenoma and duodenal adenocarcinoma. Newer endoscopic techniques, including magnifying endoscopy, may help to guide these diagnostics, but their additional advantages remain unclear, and further studies are required to clarify these issues.

Abstract
BACKGROUND AND STUDY AIMS Familial adenomatous polyposis (FAP) is associated with an increased risk of development of periampullary and nonampullary adenoma. Either routine biopsy or endoscopic removal of the lesion is generally required to identify the presence of adenoma. Because the risk of tissue sampling from the ampulla is high and nonampullary polyps are sometimes numerous, resection of all the lesions is time-consuming. This study aimed to evaluate the diagnostic values of duodenal adenoma by dual focus NBI (dNBI) and probe-based confocal endomicroscopy (pCLE) in FAP patients. PATIENTS AND METHODS The authors conducted a diagnostic study in a single tertiary-care referral center. Surveillance esophagogastroduodenoscopy with dNBI and pCLE was performed on 26 patients with FAP for real-time adenoma diagnosis by two different endoscopists; one used dNBI and the other pCLE. Histology from the matched lesion was used as the gold standard. RESULTS A total of 55 matched biopsies (25 ampullas, 30 nonampullas) were performed. The sensitivity, specificity, post predictive value (PPV), negative predictive value (NPV), and accuracy of dNBI vs. pCLE from all duodenal lesions were 96.9 % vs. 93.8 %, 78.3 % vs. 81 %, 86.1 % vs. 88.2 %, 94.7 vs. 89.5 %, and 92.4 % vs. 88.6 %, respectively. CONCLUSIONS For surveillance of periampullary and nonampullary adenoma in patients with FAP, the real-time readings provided a high degree of diagnostic value when histology was used as the gold standard.

Abstract
Currently, the strategy for real-time endoscopic diagnosis of duodenal, including ampullary, adenoma is still unclear. In the era of high-definition and magnification endoscopy, using this modality for the detection and diagnosis of these neoplasms is very challenging for endoscopists. Over the past 10 years, many instruments have been developed to improve the detection rate of duodenal and ampullary polyps and to distinguish between adenoma and non-adenoma. The present review will focus on these novel methods and their usefulness in the diagnosis of ampullary and non-ampullary adenoma.

Abstract
Despite being the current gold standard, white-light endoscopy may miss a significant proportion of lesions within the colorectum, thus leading to a misinterpretation of various disease findings. Traditionally, dye-based chromoendoscopy is used to improve both detection and characterization of lesions during luminal gastrointestinal (GI) endoscopy. Recently introduced dye-less chromoendoscopy (DLC) techniques have overcome many of the limitations of dye-based chromoendoscopy, thereby potentially improving lesion recognition and characterization. In detail, DLC techniques allow for better detection of esophageal lesions, gastric cancer and colorectal pathologies including colorectal polyps and inflammatory bowel diseases. Moreover, DLC techniques enable a more precise characterization of lesions throughout the whole luminal GI tract, thereby potentially enabling more accurate endoscopic therapies. In the present review we focus on the newly introduced dye-less chromoendoscopy technique i-scan and give an additional outlook on the recent development of optical enhancement technology.

Abstract
Celiac disease (CD) is an autoimmune disease of the small bowel induced by ingestion of wheat, rye and barley. Current guidelines indicate histological analysis on at least four duodenal biopsies as the only way to diagnose CD. These indications are based on the conception of the inability of standard endoscopy to make diagnosis of CD and/or to drive biopsy sampling. Over the last years, technology development of endoscopic devices has greatly ameliorated the accuracy of macroscopic evaluation of duodenal villous pattern, increasing the diagnostic power of endoscopy of CD. The aim of this paper is to review the new endoscopic tools and procedures proved to be useful in the diagnosis of CD, such as chromoendoscopy, Fujinon Intelligent Chromo Endoscopy, Narrow Band Imaging, Optical Coherence Tomography, Water-Immersion Technique, confocal laser endomicroscopy, high-resolution magnification endoscopy, capsule endoscopy and I-Scan technology.

Narrow band imaging with magnification endoscopy for celiac disease: results from a prospective, single-center study. DIAGNOSTIC AND THERAPEUTIC ENDOSCOPY 2013; 2013:580526.

Abstract
In celiac disease (CD), the intestinal lesions can be patchy and partial villous atrophy may elude detection at standard endoscopy (SE). Narrow Band Imaging (NBI) system in combination with a magnifying endoscope (ME) is a simple tool able to obtain targeted biopsy specimens. The aim of the study was to assess the correlation between NBI-ME and histology in CD diagnosis and to compare diagnostic accuracy between NBI-ME and SE in detecting villous abnormalities in CD. Forty-four consecutive patients with suspected CD undergoing upper gastrointestinal endoscopy have been prospectively evaluated. Utilizing both SE and NBI-ME, observed surface patterns were compared with histological results obtained from biopsy specimens using the k-Cohen agreement coefficient. NBI-ME identified partial villous atrophy in 12 patients in whom SE was normal, with sensitivity, specificity, and accuracy of 100%, 92.6%, and 95%, respectively. The overall agreement between NBI-ME and histology was significantly higher when compared with SE and histology (kappa score: 0.90 versus 0.46; P = 0.001) in diagnosing CD. NBI-ME could help identify partial mucosal atrophy in the routine endoscopic practice, potentially reducing the need for blind biopsies. NBI-ME was superior to SE and can reliably predict in vivo the villous changes of CD.

Abstract
Enhanced visualization techniques are available for Barrett's esophagus and have promise in the detection of dysplasia and cancer. Several of these techniques, such as narrow band imaging and chromoendoscopy, are being applied clinically. These techniques will allow the endoscopist to screen the surface of the Barrett's esophagus to detect areas of neoplasia. Once detected, it is hoped that either magnification techniques, such as confocal laser endomicroscopy, or spectroscopic techniques can be of value in allowing in vivo real-time diagnostic capabilities.

Abstract
BACKGROUND AND AIM Gastric metaplasia (GM) of the duodenum is difficult to assess because of its patchy distribution, and the role of GM in functional dyspepsia (FD) is not clear. The aims of this study were to determine if endomicroscopy could identify GM of the duodenum and whether GM has associations with FD. METHODS A series of 51 patients with FD and 25 asymptomatic controls were enrolled. Confocal laser endomicroscopy was performed to evaluate villi changes in vivo. Targeted biopsy specimens were then compared with histopathological results. RESULTS The accuracy of the endomicroscopy diagnosis of GM during endoscopy was 92.8%, and the sensitivity, specificity, and positive and negative predictive values were 86.2%, 97.4%, 89.3%, and 96.6%, respectively. The mean κ-value for interobserver agreement was 0.89. GM in the duodenal bulb was more frequent in patients with FD than in the controls (33.3% vs 12%, P<0.05), especially in patients with epigastric pain syndrome (47.6% vs 12%, P<0.01). CONCLUSIONS Endomicroscopy is useful for identifying GM, and GM might be related to FD. These findings could have potential applicability for duodenal screening, and suggest a possible targeting therapy in FD.

Abstract
A successful population-based colorectal cancer screening requires efficient colonoscopy practices that incorporate high throughput, safety, and patient satisfaction. There are several different modalities of nonanesthesiologist-administered sedation currently available and in development that may fulfill these requirements. Modern-day gastroenterology endoscopic procedures are complex and demand the full attention of the attending gastroenterologist and the complete cooperation of the patient. Many of these procedures will also require the anesthesiologist's knowledge, skills, abilities, and experience to ensure optimal procedure results and good patient outcomes. The goal of this review is (1) to provide a gastroenterology perspective on the use of propofol in gastroenterology endoscopic practice, and (2) to describe newer GI endoscopy procedures that gastroenterologists perform that might involve anesthesiologists.

Abstract
Despite advances in our knowledge of celiac disease, the most current and authoritative recommendations conclude that diagnosis requires at least four biopsy specimens to be taken from the duodenal area. These recommendations are based on the perception that classic endoscopic markers are not adequate to target biopsy sampling to sites of villous damage in the duodenum. In the past few years, newly developed procedures and technologies have improved endoscopic recognition of the duodenum. These advances make possible the real-time recognition of the duodenal villous pattern during an upper endoscopy procedure, and thereby have the potential to optimize diagnostic accuracy. It is, therefore, reasonable to hypothesize that upper endoscopy might have a more incisive role in the diagnosis of celiac disease than merely providing a means of obtaining biopsy specimens for histological analysis. This Review highlights the new technologies in the field of upper endoscopy that could be helpful for the diagnosis of celiac disease, including the water-immersion technique, chromoendoscopy, high-resolution magnification endoscopy, optimal band imaging, optical coherence tomography and confocal endomicroscopy.

Abstract
Coeliac disease is an autoimmune enteropathy precipitated by the gluten content of cereals. It had for long been considered a childhood condition as clinical symptoms manifested when gluten was introduced into the diet. The introduction of specific serological markers changed our understanding of the epidemiology and semiology of the syndrome. The main difficulty of the diagnostics arises from the fact that over 50% of patients with gluten-sensitive enteropathy show atypical symptoms, while coeliac-disease patients with extra-gastrointestinal manifestations show no gastrointestinal symptoms at all. Diagnostics of coeliac disease is currently based on the detection of specific antibodies and the histological assessment of the duodenum. Macroscopic signs of villous atrophy (reduction in the number or loss of Kerking's folds, vascular pattern visible through the mucosa, "mosaic or micronodular" pattern, "scalloped" folds) are clearly visible in untreated patients. Capsule endoscopy, contrary to conventional endoscopic approaches, enables non-invasive, pain-free investigation of the entire small intestine. Duodenal mucosa is visualised at an 8:1 magnification during the investigation, enabling the assessment of villous atrophy by an experienced investigator. Based on preliminary experience, standard upper tract endoscopy and capsule endoscopy appear to exhibit equal levels of sensitivity and specificity for coeliac disease. The advantage of CE versus upper tract endoscopy lies in the complete assessibility of the small intestine, thus also enabling the assessment of the spread and severity of the disease. The disadvantage associated with the approach is the lack of histological biopsy samples. CE is recommendable as a first line approach for patients with proven coeliac disease when alarm conditions appear.

Abstract
BACKGROUND Intestinal lesions in celiac disease (CD) and tropical sprue (TS) can be patchy. Improved endoscopic identification of affected areas may increase the diagnostic yield of biopsy specimens. Enhanced magnification endoscopy [EME] combines magnification endoscopy with 3% acetic acid instillation. OBJECTIVE This study describes endoscopic findings associated with villous atrophy during EME. DESIGN Patients underwent EME with a magnifying endoscope with acetic-acid application. Surface mucosal patterns were characterized before and after acetic-acid spraying. Observed surface patterns were compared with histologic results obtained from a single targeted biopsy specimen. SETTING Policlinica Metropolitana in Caracas, Venezuela. PATIENTS Patients with diagnosed but untreated CD or TS. RESULTS Fifty-two biopsy specimens were obtained from 27 patients (17 men, 10 women; mean age 50.5 years; range, 24-76 years; 12 with CD and 15 with TS). EME of the duodenum revealed 4 different mucosal patterns: I, normal; II, stubbed; III, ridged; and IV, foveolar. Three of the 4 patterns were strongly associated with the presence of villous atrophy (pattern I, 1/18 [5.5%]; II, 16/17 [94%]; III, 12/12 [100%]; and IV, 5/5 [100%]). EME was more sensitive than standard endoscopy for detecting villous atrophy, 100% versus 58% in CD and 93% versus 20% in TS. Furthermore, EME identified patchy areas of partial villous atrophy in 16 patients (5 CD and 11 TS) in whom standard endoscopy was normal. CONCLUSIONS EME identifies 3 characteristic endoscopic patterns that correlate with the presence of villous atrophy. EME could help identify patchy areas of partial mucosal atrophy, potentially reducing the need for blind biopsies.

Abstract
OBJECTIVE To review the drug compounding of dyes employed in chromoendoscopy, and their clinical effectiveness. METHOD A literature search in Medline, Cochrane Library, and Micromedex was carried out with the term chromoendoscopy as a keyword, and the search was then repeated for each dye found in association with the term endoscopy. A number of monographs, scientific journals, and references quoted in selected papers were also reviewed. Papers collected were then classified according to their methodology. RESULTS Ninety-six references were found, their original article being recovered for only 57 of these - 13 clinical trials, 21 case series, and 11 reviews. References were found for 7 dyes. Main indications, evidence of effectiveness, administration route, and drug formulation are described for each dye. CONCLUSIONS The number of papers involved is high, but their accessibility is limited. Evidence is overall scarce, but high in cases such as methylene blue for Barrett s esophagus, lugol in the detection of esophageal carcinoma, and indigo carmine for colonic hyperplastic polyp differentiation. Drug compounding is rather simple, but scarcely developed.

Abstract
The major role for chromoendoscopy in the esophagus is the identification of premalignant or early cancerous lesions. In combination with high-resolution or magnification endoscopes, chromoendoscopy can potentially increase the diagnostic yield of clinically relevant lesions. Preliminary data have indicated a good correlation of findings using this technique to histopathologic readings. The ultimate goal of chromoendoscopy in combination with high resolution/magnification endoscopy is the determination of histology without obtaining tissue samples. In this article we review the different stains, the technical aspects, and current data in esophageal chromoendoscopy. We summarize possible clinical applications of these techniques and future directions of their use in esophageal diseases.
