Abstract
BACKGROUND AND AIM Current treatments for refractory benign esophageal strictures (BESs) often take several years and have poor effects. The authors propose a novel method of self-help inflatable balloon (SHIB) and evaluate its efficacy and safety. METHODS A prospective, multicenter study was conducted from January 2019 to March 2022. All enrolled patients were diagnosed with refractory BESs and received SHIB. The primary endpoint was the clinical success rate at 12 months after removing SHIB. The secondary endpoints were the number of days of placing SHIB, and changes from baseline in BMI and health-related quality of life at 1, 3, 6, and 12 months. RESULTS The clinical success rate was 51.2% (21/41) with the median days of placing SHIB being 104.0 days (range: 62.0-134.5 days), which was higher in the endoscopic group compared to the caustic and surgery groups (63.3 vs. 28.6% vs. 0, P=0.025). All patients (100%) showed significant improvement in dysphagia scores during placing SHIB. Although 20 patients (48.8%) experienced recurrent stricture, the median stricture length was decreased (P<0.001) and the median intervention-free interval was prolonged (P<0.001). In all patients, the mean BMI at and health-related quality of life at 1, 3, 6, and 12 months were significantly increased compared with baseline (P<0.05). On multivariate analysis, stricture etiology and wearing time were independent predictors of recurrent stricture. CONCLUSIONS The SHIB has high efficacy and safety in treating refractory BESs of different origins, especially for endoscopic resection. Stricture etiology and wearing time were independent predictors of recurrent stricture.

Abstract
BACKGROUND Treatment of dysplastic Barrett's oesophagus prevents progression to adenocarcinoma; however, the optimal diagnostic strategy for Barrett's oesophagus is unclear. The Cytosponge-trefoil factor 3 (TFF3) is a non-endoscopic test for Barrett's oesophagus. The aim of this study was to investigate whether offering this test to patients on medication for gastro-oesophageal reflux would increase the detection of Barrett's oesophagus compared with standard management. METHODS This multicentre, pragmatic, randomised controlled trial was done in 109 socio-demographically diverse general practice clinics in England. Randomisation was done both at the general practice clinic level (cluster randomisation) and at the individual patient level, and the results for each type of randomisation were analysed separately before being combined. Patients were eligible if they were aged 50 years or older, had been taking acid-suppressants for symptoms of gastro-oesophageal reflux for more than 6 months, and had not undergone an endoscopy procedure within the past 5 years. General practice clinics were selected by the local clinical research network and invited to participate in the trial. For cluster randomisation, clinics were randomly assigned (1:1) by the trial statistician using a computer-generated randomisation sequence; for individual patient-level randomisation, patients were randomly assigned (1:1) by the general practice clinics using a centrally prepared computer-generated randomisation sequence. After randomisation, participants received either standard management of gastro-oesophageal reflux (usual care group), in which participants only received an endoscopy if required by their general practitioner, or usual care plus an offer of the Cytosponge-TFF3 procedure, with a subsequent endoscopy if the procedure identified TFF3-positive cells (intervention group). The primary outcome was the diagnosis of Barrett's oesophagus at 12 months after enrolment, expressed as a rate per 1000 person-years, in all participants in the intervention group (regardless of whether they had accepted the offer of the Cytosponge-TFF3 procedure) compared with all participants in the usual care group. Analyses were intention-to-treat. The trial is registered with the ISRCTN registry, ISRCTN68382401, and is completed. FINDINGS Between March 20, 2017, and March 21, 2019, 113 general practice clinics were enrolled, but four clinics dropped out shortly after randomisation. Using an automated search of the electronic prescribing records of the remaining 109 clinics, we identified 13 657 eligible patients who were sent an introductory letter with 14 days to opt out. 13 514 of these patients were randomly assigned (per practice or at the individual patient level) to the usual care group (n=6531) or the intervention group (n=6983). Following randomisation, 149 (2%) of 6983 participants in the intervention group and 143 (2%) of 6531 participants in the usual care group, on further scrutiny, did not meet all eligibility criteria or withdrew from the study. Of the remaining 6834 participants in the intervention group, 2679 (39%) expressed an interest in undergoing the Cytosponge-TFF3 procedure. Of these, 1750 (65%) met all of the eligibility criteria on telephone screening and underwent the procedure. Most of these participants (1654 [95%]; median age 69 years) swallowed the Cytosponge successfully and produced a sample. 231 (3%) of 6834 participants had a positive Cytosponge-TFF3 result and were referred for an endoscopy. Patients who declined the offer of the Cytosponge-TFF3 procedure and all participants in the usual care group only had an endoscopy if deemed necessary by their general practitioner. During an average of 12 months of follow-up, 140 (2%) of 6834 participants in the intervention group and 13 (<1%) of 6388 participants in the usual care group were diagnosed with Barrett's oesophagus (absolute difference 18·3 per 1000 person-years [95% CI 14·8-21·8]; rate ratio adjusted for cluster randomisation 10·6 [95% CI 6·0-18·8], p<0·0001). Nine (<1%) of 6834 participants were diagnosed with dysplastic Barrett's oesophagus (n=4) or stage I oesophago-gastric cancer (n=5) in the intervention group, whereas no participants were diagnosed with dysplastic Barrett's oesophagus or stage I gastro-oesophageal junction cancer in the usual care group. Among 1654 participants in the intervention group who swallowed the Cytosponge device successfully, 221 (13%) underwent endoscopy after testing positive for TFF3 and 131 (8%, corresponding to 59% of those having an endoscopy) were diagnosed with Barrett's oesophagus or cancer. One patient had a detachment of the Cytosponge from the thread requiring endoscopic removal, and the most common side-effect was a sore throat in 63 (4%) of 1654 participants. INTERPRETATION In patients with gastro-oesophageal reflux, the offer of Cytosponge-TFF3 testing results in improved detection of Barrett's oesophagus. Cytosponge-TFF3 testing could also lead to the diagnosis of treatable dysplasia and early cancer. This strategy will lead to additional endoscopies with some false positive results.

Abstract
PURPOSE OF REVIEW Functional lumen impedance (FLIP) technology has become commercially available to assess structural and motor abnormalities of the esophagus. Increasing numbers of papers have described novel findings with this technology. This review examines the validity of the FLIP technique, how it compares with existing diagnostic modalities, and evidence to date on diagnostic accuracy. RECENT FINDINGS FLIP studies require deep sedation at the time of endoscopy to complete. They assess a simulated state of esophageal obstruction in only a distal part of the esophagus rather than deglutitive motor function of the entire esophagus. The available normative dataset is small and not matched to the older age of patients typically being evaluated. The test-retest agreement in health and disease is unknown, as is the operator dependence on performing and interpreting findings. Studies to date have largely excluded patients with structural disorders, which FLIP cannot reliably distinguish from motor disorders. FLIP is an expensive technology that has been made clinically available without its true utility being established. For FLIP to be deemed a device ready for widespread clinical use, additional studies on validity, diagnostic accuracy, and outcomes need to be performed. Prospective clinical studies need to include all patients and assess the incremental cost-effectiveness of FLIP over more innovative use of existing technology, such as high-resolution manometry with provocative challenges.

Abstract
Radiofrequency ablation (RFA) is very effective for eradication of flat Barrett’s mucosa in dysplastic Barrett’s esophagus after endoscopic resection of raised lesions. However, in a minority of the time, RFA may be ineffective at eradication of the Barrett’s mucosa. Achieving complete eradication of intestinal metaplasia can be challenging in these patients. This review article focuses on the management of patients with dysplastic Barrett’s esophagus refractory to RFA therapy. Management strategies discussed in this review include optimizing the RFA procedure, optimizing acid suppression (with medical, endoscopic, and surgical management), cryotherapy, hybrid argon plasma coagulation, and EndoRotor resection.

Abstract
PURPOSE OF REVIEW The functional luminal imaging probe (FLIP) uses high-resolution planimetry to provide a three-dimensional image of the esophageal lumen by measuring diameter, volume, and pressure changes. The goal of this review is to summarize the most recent advances in applying the (FLIP) to esophageal disorders. RECENT FINDINGS The FLIP has been studied in esophageal disease states including gastroesophageal reflux disease (GERD), achalasia, and eosinophilic esophagitis. It has also been used in the investigation of dysphagia. The FLIP is a valuable tool for the diagnosis of esophageal diseases as well as guiding treatments and predicting treatment response. As further research is done, the FLIP may become the initial test for the patient with undifferentiated dysphagia at the time of their index endoscopy.

Abstract
OBJECTIVES The objective of this study is to analyze and report the institution's experience using the Enseal bipolar tissue sealing device to perform endoscopic Zenker's diverticulotomy. Safety and early functional outcomes are presented as primary endpoints of the study. MATERIALS & METHODS This is a retrospective study of consecutive patients with Zenker's diverticulum (ZD) treated via a transoral approach using a rigid endoscope and a bipolar tissue sealer between 2011 and 2019. Demographic data, ZD size, complications and preoperative versus postoperative symptoms were assessed. The Eating Assessment Tool-10 (EAT-10) questionnaire was used to evaluate functional outcomes, and statistical comparisons were made using the student's t-test. RESULTS Nineteen ZD patients were identified who underwent rigid endoscopic diverticulotomy using a bipolar tissue sealer. The mean age was 71 years and 74% were male. The mean diverticulum size was 3.1 cm. There were no intraoperative or postoperative complications identified. Average pre-operative EAT-10 score was 21 and post-operative EAT-10 score was 12 at one to two weeks after surgery (p = .05). CONCLUSIONS Evidence from this preliminary study of endoscopic Zenker's diverticulotomy using the Enseal device indicates that it is both safe and effective. Several features of the device, including its narrow profile, articulation and rotation capability, rapid repeatable activation, and low risk of collateral thermal injury, make it an appealing option for endoscopic Zenker's diverticulotomy.

Abstract
RATIONALE The ingestion of a foreign body (FB) with complete impaction of the esophagus is not common. Here we report a rare case of successful retrieval of a spherical stone in the esophagus of a man with mental retardation, using gallbladder grasping forceps and rigid endoscope. PATIENT CONCERNS A mental retarded man came to the emergency department presenting with recurrent nausea, vomiting, and dysphagia after swallowing a spherical stone. He had previously undergone an FB extraction under general anesthesia by fiberoptic esophagoscopy, which failed. DIAGNOSIS The diagnosis of FB ingestion was confirmed by anteroposterior plain film x-ray of the chest and chest computed tomography (CT), which showed the ingested spherical FB in the upper esophagus. INTERVENTIONS After multiple failed attempts using other instruments, the FB was successfully removed with gallbladder grasping forceps through a rigid esophagoscope. OUTCOMES The patient was discharged without any complications. The nasogastric tube was extubated at the 10-day follow-up. LESSONS SUBSECTIONS AS PER STYLE For esophageal retrieval of uncommon FBs, the instrument used is crucial. We report our experience retrieving a large and spherical FB in the upper esophagus using gallbladder grasping forceps. This proved to be an effective strategy, eliminating the need for thoracotomy.

Abstract
Achalasia was first described in the 17th century and its treatment continues to be challenging. Palliative treatment involves disruption of the lower esophageal sphincter, which can be accomplished mechanically (balloon dilation or surgical myotomy) or chemically (Botox). True surgical treatment originated some 100 years ago and remained largely unchanged until the advent of thoracoscopic and then laparoscopic myotomy beginning in the 1980s. Because these procedures provided relatively definitive treatment and were well tolerated by patients, minimal invasive surgery assumed a primary role in the treatment algorithms for achalasia. In 2008, an endoscopic (incision-less) myotomy approach, per-oral endoscopic myotomy, was described. This even less invasive approach has rapidly been adopted in the majority of high-volume achalasia centers. Newer interventions, such as stenting and cell transplant, are under active investigation.

Abstract
Hyperspectral imaging (HSI) enables visualisation of morphological and biochemical information, which could improve disease diagnostic accuracy. Unfortunately, the wide range of image distortions that arise during flexible endoscopy in the clinic have made integration of HSI challenging. To address this challenge, we demonstrate a hyperspectral endoscope (HySE) that simultaneously records intrinsically co-registered hyperspectral and standard-of-care white light images, which allows image distortions to be compensated computationally and an accurate hyperspectral data cube to be reconstructed as the endoscope moves in the lumen. Evaluation of HySE performance shows excellent spatial, spectral and temporal resolution and high colour fidelity. Application of HySE enables: quantification of blood oxygenation levels in tissue mimicking phantoms; differentiation of spectral profiles from normal and pathological ex vivo human tissues; and recording of hyperspectral data under freehand motion within an intact ex vivo pig oesophagus model. HySE therefore shows potential for enabling HSI in clinical endoscopy.

Abstract
Esophageal diverticula are rare conditions that cause esophageal symptoms, such as dysphagia, regurgitation, and chest pain. They are classified according to their location and characteristic pathophysiology into three types: epiphrenic diverticulum, Zenker’s diverticulum, and Rokitansky diverticulum. The former two disorders take the form of protrusions, and symptomatic cases require interventional treatment. However, the esophageal anatomy presents distinct challenges to surgical resection of the diverticulum, particularly when it is located closer to the oral orifice. Since the condition itself is not malignant, minimally invasive endoscopic approaches have been developed with a focus on alleviation of symptoms. Several types of endoscopic devices and techniques are currently employed, including peroral endoscopic myotomy (POEM). However, the use of minimally invasive endoscopic approaches, like POEM, has allowed the development of new disorder called iatrogenic esophageal diverticula. In this paper, we review the pathophysiology of each type of diverticulum and the current state-of-the-art treatment based on our experience.

Abstract
BACKGROUND This study assessed the efficacy of autofluorescence endoscopy (AFE) using the Onco-LIFE system and numerical color value (NCV) estimation in comparison to white light endoscopy (WLE) in endoscopic surveillance for identification of early dysplasia in Barrett's esophagus (BE) to aid in real-time image elucidation and minimize the overreliance on biopsy and histology. METHODS AFE, performed simultaneously during WLE, with biopsy was performed among 24 patients with BE. None of these patients had any obvious mucosal abnormalities in WLE. A total of 376 biopsies were taken, include 325 randomly collected according to Seattle Protocol and 51 additional biopsies, taken from the sites with pathological AF and NCV. All biopsy sites were assessed in vivo using WLE, AFE and NCV and compared to histological examinations, to estimate the efficacy of these methods in dysplasia assessment in BE. RESULTS In the case of 248 biopsies taken from sites with NCV below 1.0, two cases of unspecified dysplasia were recognized; in 14 biopsies with NCV above 2.0 in all cases the various grades of dysplasia were documented. Dysplasia was found in 42% of AFE + NCV- guided biopsy specimens, and in 7.1% of WLE-guided biopsy specimens. AFE + NCV detected high-grade dysplasia in 7 patients, 6 more than according to Seattle Protocol in WLE. The expected odds of dysplasia detection in a sample increases almost 1.9 times, if it was selected by the AFE method (p < 0.001), when compared to WLE and with accordance with Seattle Protocol guided biopsy. CONCLUSION The above results indicate that AFE + NCV using the Onco-LIFE system leads to improved BE lesion visualization for targeted biopsy with accurate histologic correlation compared to WLE and Seattle Protocol guided biopsy alone, and can serve to minimize additional biopsies.

Abstract
PURPOSE To evaluate the feasibility of self-expanding metal stent (SEMS) placement and fluorescence microendoscopic monitoring for determination of fibroblast cell proliferation after stent placement in an esophageal mouse model. MATERIALS AND METHODS Twenty fibroblast-specific protein (FSP)-1 green fluorescent protein (GFP) transgenic mice were analyzed. Ten mice (Group A) underwent SEMS placement, and fluoroscopic and fluorescence microendoscopic images were obtained biweekly until 8 weeks thereafter. Ten healthy mice (Group B) were used for control esophageal values. RESULTS SEMS placement was technically successful in all mice. The relative average number of fibroblast GFP cells and the intensities of GFP signals in Group A were significantly higher than in Group B after stent placement. The proliferative cellular response, including granulation tissue, epithelial layer, submucosal fibrosis, and connective tissue, was increased in Group A. FSP-1-positive cells were more prominent in Group A than in Group B. CONCLUSIONS SEMS placement was feasible and safe in an esophageal mouse model, and proliferative cellular response caused by fibroblast cell proliferation after stent placement was longitudinally monitored using a noninvasive fluorescence microendoscopic technique. The results have implications for the understanding of proliferative cellular response after stent placement in real-life patients and provide initial insights into new clinical therapeutic strategies for restenosis.

Abstract
Esophageal carcinoma is a highly lethal cancer associated with high morbidity and mortality. Esophageal squamous cell carcinoma and esophageal adenocarcinoma are the two distinct histological types. There has been significant progress in endoscopic diagnosis and treatment of early stages of cancer using resection and ablation techniques, as shown in several trials in the recent past. Earlier detection of esophageal cancer and advances in treatment modalities have lead to improvement in the 5-year survival from 5% to about 20% in the past decade. Endoscopic eradication therapy is the preferred modality of treatment in cancer limited to mucosal layer of the esophagus as there is very low risk of lymph node metastasis, leading to high cure rates, low risk of recurrence and with few adverse effects. The most common adverse events seen are strictures, bleeding and rarely perforation which can be endoscopically managed. In patients with recurrent advanced disease or invasive tumor, esophagectomy with lymph node dissection remains the mainstay of treatment. There is debate on post-endoscopic surveillance with some studies suggesting closer follow up with upper endoscopy every 6 mo for the first 1-2 years and then annually for the 3 years while others recommending the appropriate action only if symptoms or other abnormalities develop. Overall, the field of endoscopic therapy is still evolving and focus should be placed on careful patient selection using a multidisciplinary approach.

Abstract
Stent migration, which causes issues in stent therapy for esophageal perforations, can counteract the therapeutic effects and lead to complications. Therefore, techniques to regulate stent migration are important and lead to effective stent therapy. Here, in these cases, we placed a removable fully covered self-expandable metallic stent (FSEMS) in a 52-year-old man with suture failure after surgery to treat Boerhaave syndrome, and in a 53-year-old man with a perforation in the lower esophagus due to acute esophageal necrosis. At the same time, we nasally inserted a Sengstaken-Blakemore tube (SBT), passing it through the stent lumen. By inflating a gastric balloon, the lower end of the stent was supported. When the stent migration was confirmed, the gastric balloon was lifted slightly toward the oral side to correct the stent migration. In this manner, the therapy was completed for these two patients. Using a FSEMS and SBT is a therapeutic method for correcting stent migration and regulating the complete migration of the stent into the stomach without the patient undergoing endoscopic rearrangement of the stent. It was effective for positioning a stent crossing the esophagogastric junction.

Abstract
Procedures and outcomes for pediatric esophageal foreign body removal were analyzed. Traditional methods of battery removal were compared with a magnetic tip orogastric tube (MtOGT). A single institution retrospective review from 1997 to 2014 of pediatric patients with esophageal foreign bodies was performed. Balloon extraction with fluoroscopy (performed in 173 patients with 91% success), flexible endoscopy (92% success in 102 patients), and rigid esophagoscopy (95% in 38 patients) had excellent success rates. A MtOGT had 100 per cent success in six disc battery patients, when other methods were more likely to fail, and was the fastest. Power analysis suggested 20 patients in the MtOGT group would be needed for significant savings in procedural time. Thirty-two per cent of all foreign bodies and 95 per cent of batteries had complications (P = 0.002) because of the foreign body. Overall, 1.2 per cent had severe complications, whereas 10 per cent of batteries had severe complications (P = 0.04). Each technique if applied appropriately can be a reasonable option for esophageal foreign body removal. Magnetic tip orogastric tubes used to extract ferromagnetic objects like disc batteries had the shortest procedure time and highest success rate although it was not statistically significant. Disc batteries require emergent removal and have a significant complication rate.

Abstract
RATIONALE Tracheal injury characterized by subcutaneous emphysema and dyspnea can occur following the use of a Sengstaken-Blakemore tube. Should tracheal injury occur, it may be possible to manage resultant airway obstruction with a tracheal stent. PATIENT CONCERNS We describe the case of a 51-year-old patient who developed a tracheal injury when a Sengstaken-Blakemore tube was inadvertently inserted into the patient's trachea. DIAGNOSES Liver cirrhosis, gastric-fundus variceal bleeding, tracheal injury. INTERVENTIONS Polyglycol and tissue glue were injected intravenously, and endoscopic variceal ligation was performed. A Sengstaken-Blakemore tube was used to stop the bleeding. A covered tracheal stent was placed via fiberoptic bronchoscopy to relieve the tracheal injury due to improper placement of a Sengstaken-Blakemore tube. OUTCOMES After placement of the tracheal stent, the patient was able to breathe spontaneously and subsequently recovered. LESSONS Some precautions must be taken to avoid placing a Sengstaken-Blakemore tube in the trachea. If a tracheal injury occurs following misplacement of a Sengstaken-Blakemore tube, it may be possible to manage resultant airway obstruction by placing a tracheal stent.

Abstract
Barrett's oesophagus is an acquired metaplastic condition that predisposes patients to the development of oesophageal adenocarcinoma, prompting the use of surveillance regimes to detect early malignancy for endoscopic therapy with curative intent. The currently accepted surveillance regime uses white light endoscopy together with random biopsies, but has poor sensitivity and discards information from numerous light-tissue interactions that could be exploited to probe structural, functional, and molecular changes in the tissue. Advanced optical methods are now emerging that are highly sensitive to these changes and hold potential to improve surveillance of Barrett's oesophagus if they can be applied endoscopically. The next decade will see some of these exciting new methods applied to surveillance of Barrett's oesophagus in new device architectures for the first time, potentially leading to a long-awaited improvement in the standard of care.

Abstract
AIM To determine short- and long-term outcomes of endoscopic submucosal dissection (ESD) using the stag beetle (SB) knife, a scissor-shaped device.
METHODS Seventy consecutive patients with 96 early esophageal neoplasms, who underwent ESD using a SB knife at Kure Medical Center and Chugoku Cancer Center, Japan, between April 2010 and August 2016, were retrospectively evaluated. Clinicopathological characteristics of lesions and procedural adverse events were assessed. Therapeutic success was evaluated on the basis of en bloc, histologically complete, and curative or non-curative resection rates. Overall and tumor-specific survival, local or distant recurrence, and 3- and 5-year cumulative overall metachronous cancer rates were also assessed.
RESULTS Eligible patients had dysplasia/intraepithelial neoplasia (22%) or early cancers (squamous cell carcinoma, 78%). The median procedural time was 60 min and on average, the lesions measured 24 mm in diameter, yielding 33-mm tissue defects. The en bloc resection rate was 100%, with 95% and 81% of dissections deemed histologically complete and curative, respectively. All procedures were completed without accidental incisions/perforations or delayed bleeding. During follow-up (mean, 35 ± 23 mo), no local recurrences or metastases were observed. The 3- and 5-year survival rates were 83% and 70%, respectively, with corresponding rates of 85% and 75% for curative resections and 74% and 49% for non-curative resections. The 3- and 5-year cumulative rates of metachronous cancer in the patients with curative resections were 14% and 26%, respectively.
CONCLUSION ESD procedures using the SB knife are feasible, safe, and effective for treating early esophageal neoplasms, yielding favorable short- and long-term outcomes.

Abstract
Pneumatic dilation is a well-established treatment modality that has withstood the test of time. Prospective and randomized trials have shown that in expert hands, it provides results similar to a laparoscopic Heller myotomy with fundoplication. In addition, it should be considered the primary form of treatment in patients who experience recurrence of symptoms after a surgical myotomy.

Abstract
AIM To assess the effect of polyglycolic acid (PGA) plus stent placement compared with stent placement alone in the prevention of post-endoscopic submucosal dissection (ESD) esophageal stricture in early-stage esophageal cancer (EC) patients.
METHODS Seventy EC patients undergoing ESD were enrolled in this randomized, controlled study. Patients were allocated randomly at a 1:1 ratio into two groups as follows: (1) PGA plus stent group (PGA sheet-coated stent placement was performed); and (2) Stent group (only stent placement was performed). This study was registered on http://www.chictr.org.cn (No. chictr-inr-16008709).
RESULTS The occurrence rate of esophageal stricture in the PGA plus stent group was 20.5% (n = 7), which was lower than that in the stent group (46.9%, n = 15) (P = 0.024). The mean value of esophageal stricture time was 59.6 ± 16.1 d and 70.7 ± 28.6 d in the PGA plus stent group and stent group (P = 0.174), respectively. Times of balloon dilatation in the PGA plus stent group were less than those in the stent group [4 (2-5) vs 6 (1-14), P = 0.007]. The length (P = 0.080) and diameter (P = 0.061) of esophageal strictures were numerically decreased in the PGA plus stent group, whereas no difference in location (P = 0.232) between the two groups was found. Multivariate logistic analysis suggested that PGA plus stent placement (P = 0.026) was an independent predictive factor for a lower risk of esophageal stricture, while location in the middle third (P = 0.034) and circumferential range = 1/1 (P = 0.028) could independently predict a higher risk of esophageal stricture in EC patients after ESD.
CONCLUSION PGA plus stent placement is more effective in preventing post-ESD esophageal stricture compared with stent placement alone in EC patients with early-stage disease.

Abstract
Because the esophagus is easily accessible with endoscopy, early diagnosis and curative treatment of esophageal cancer is possible. However, diagnosis is often delayed because symptoms are not specific during early stages of tumor development. The onset of dysphagia is associated with advanced disease, which has a survival at 5 years lower than 15%. Population screening by endoscopy is not cost-effective, but a number of alternative imaging and cell analysis technologies are under investigation. The ideal screening test should be inexpensive, well tolerated, and applicable to primary care. Over the past 10 years, significant progress has been made in endoscopic diagnosis and treatment of dysplasia (squamous and Barrett's), and early esophageal cancer using resection and ablation technologies supported by evidence from randomized controlled trials. We review the state-of-the-art technologies for early diagnosis and minimally invasive treatment, which together could reduce the burden of disease.

Abstract
INTRODUCTION Complete circular endoscopic (submucosal) resection (CER) performed using the endoscopic submucosal dissection (ESD) technique is burdened with a high incidence of post-operative strictures in the esophagus. The most effective method of preventing them is not known so far; one of the possible methods is to prevent these strictures directly at the site of their formation by covering the defect with a stent. The aim of the study was to find a way to fix a selected biomaterial to a stent, and subsequently, to fix the stent at the CER site to prevent esophageal strictures in an animal model. METHOD Miniature piglets from the Czech Academy of Sciences breeding unit in Libechov (N=10) were used. Endoscopy was performed using a single-channel endoscope. First, we made two circular mucosal cuts spaced 5 cm apart in the middle esophagus and we performed the CER between them using the endoscopic submucosal dissection technique. After that, we covered the defect with a stent coated with biomaterial (Xe-Derma®) while we tried to prevent stent migration into the stomach. For stent fixation, we tested endo-clips (N=3), the Apollo endoscopic system (N=1) and the suspension technique using two polyamide threads (N=6) anchored in the nasal septum. We performed a control endoscopy, stent removal and subsequent autopsy after 12 weeks. RESULTS All procedures were completed successfully without serious complications or deaths. Although stents covered with Xe-Derma® were applied to the entire resection area, one case of mediastinitis and one paraesophageal abscess were found during autopsy, most likely due to microperforations caused during the procedure. Histological analysis showed that after contact with the biomaterial, re-epithelisation took place within one week of application to the resection area. Stent migration occurred in each case when the stent was attached to the esophageal wall by endo-clips or with the endoscopic suture system (Apollo). There was no stent dislocation in the cases where the stent was suspended by two polyamide threads. CONCLUSION We developed a technique of fixing biomaterial to the surface of metallic stents which we used to prevent the formation of esophageal strictures after CER. Distal suspension fixation of the stent with a polyamide thread proved to be the most effective, while fixations by endo-clips or with the endoscopic suture system were ineffective.Key words: benign esophageal strictures circular endoscopic resection endoscopic submucosal dissection complication prevention.

Abstract
A 47-year-old woman presented to our hospital with complaints of dysphagia. Esophagogastroduodenoscopy identified a submucosal tumor in the left wall of the esophagus that was diagnosed as a benign schwannoma on biopsy. Computed tomography revealed a tumor of length 60 mm in the thoracic esophagus, with its cranial edge at the level of the aortic arch. On endoscopy, a submucosal tunnel was created 40 mm proximal to the cranial edge of the tumor, and its oral end was dissected from the mucosal and muscular layers. This was followed by the resection of the entire tumor by left-sided thoracoscopy. The esophageal defect was closed in layer by continuous suture from the thoracic side. Endoscopic closure was achieved by using clips. No postoperative complications were observed. Oral diet was resumed from postoperative day 7 and the patient was discharged on postoperative day 9. This combined approach has not been described for similar tumors. Our experience demonstrated that large esophageal tumors can be safely excised with minimally invasive surgery by using a combination of thoracoscopy and endoscopy.

Abstract
AIM To investigate the efficacy and safety of a combination of sufentanil and propofol injection in patients undergoing endoscopic injection sclerotherapy (EIS) for esophageal varices (EVs).
METHODS Patients with severe EVs who underwent EIS with sufentanil and propofol anesthesia between April 2016 and July 2016 at our hospital were reviewed. Although EIS and sequential therapy were performed under endotracheal intubation, we only evaluated the efficacy and safety of anesthesia for the first EIS procedure. Patients were intravenously treated with 0.5-1 μg/kg sufentanil. Anesthesia was induced with 1-2 mg/kg propofol and maintained using 2-5 mg/kg per hour of propofol. Information, regarding age, sex, weight, American Association of Anesthesiologists (ASA) physical status, Child-Turcotte-Pugh (CTP) classification, indications, preanesthetic problems, endoscopic procedure, successful completion of the procedure, anesthesia time, recovery time, and anesthetic agents, was recorded. Adverse events, including hypotension, hypertension, bradycardia, and hypoxia, were also noted.
RESULTS Propofol and sufentanil anesthesia was provided in 182 procedures involving 140 men and 42 women aged 56.1 ± 11.7 years (range, 25-83 years). The patients weighed 71.4 ± 10.7 kg (range, 45-95 kg) and had ASA physical status classifications of II (79 patients) or III (103 patients). Ninety-five patients had a CTP classification of A and 87 had a CTP classification of B. Intravenous anesthesia was successful in all cases. The mean anesthesia time was 33.1 ± 5.8 min. The mean recovery time was 12.3 ± 3.7 min. Hypotension occurred in two patients (1.1%, 2/182). No patient showed hypertension during the endoscopic therapy procedure. Bradycardia occurred in one patient (0.5%, 1/182), and hypoxia occurred in one patient (0.5%, 1/182). All complications were easily treated with no adverse sequelae. All endoscopic procedures were completed successfully.
CONCLUSION The combined use of propofol and sufentanil injection in endotracheal intubation-assisted EIS for EVs is effective and safe.

Abstract
The esophagus is one of the areas of the gastrointestinal tract, for which therapeutic concepts have changed the most over the last two decades. The most decisive advance is the development of endoscopic resection techniques for early esophageal carcinomas. These methods provide excellent short- and long-term results combined with very low morbidity and negligible mortality rates in comparison with surgical esophagectomy, especially in case of mucosal Barrett's adenocarcinoma. In addition, the endoscopic myotomy techniques in Zenker's diverticulum and spastic achalasia are new, attractive endoscopic treatment modalities.

Abstract
A 65-year-old man with cT1bN0M0 stage I middle thoracic esophageal cancer underwent subtotal esophagectomy and gastric tube reconstruction through the posterior mediastinal route after preoperative carbon-ion radiotherapy and chemotherapy in a clinical trial. Anastomotic leakage occurred, but it spontaneously improved. At six months after the operation, he was rehospitalized with a cough and dysphagia. An esophago-bronchiole fistula and stenosis of the gastric tube were observed. He first underwent stent placement in the gastric tube. Two weeks later, the syringeal epithelium was burned by argon plasma coagulation after stent removal. Endoscopic occlusion was then performed for the fistula with two guidewire-assisted silicone spigots. Two weeks later, he was discharged on an oral diet, and he has not developed recurrence of the fistula or cancer for three years. This is the first report of endoscopic occlusion with a guidewire-assisted silicone spigot through the esophagus.

Abstract
Outcome of endoscopic dilatation in acid-induced corrosive esophageal stricture is less known. This study aims to determine the outcome of dilatation and predictors of failed dilatation in patients with acid-induced corrosive esophageal stricture. Patients diagnosed of corrosive esophageal strictures were included. Endoscopic dilatation with graded Savary-Gilliard dilator was performed as the first line treatment. Outcome of dilatation was considered favorable when patients were able to swallow solid without intervention at least six months after successful dilatation. Failure of dilatation was defined as one of the following; complete luminal stenosis, inability to perform safe dilatation, perforation, and inability to maintain adequate luminal patency. Surgery or repeated dilatation was indicated in failed dilatations. There were 55 patients with corrosive esophageal strictures. Of 55 patients, 41 (75%) had failed dilatation (38 having esophageal replacement procedure, two continue repeated dilatation and one unfit for surgery). Of 323 sessions of dilatations, eight out of 55 patients (14.5%) had perforations. There was no dilatation-related mortality. Patients with concomitant pharyngeal stricture (p = 0.0001), long (≥ 10 cm) stricture length (p < 0.0001), number of dilatation >6 sessions per year (p = 0.01) and refractory stricture (inability to pass a larger than 11 mm dilator within three sessions) (p = 0.01) were more likely to have failed dilatation. Thirty-two of 38 patients with surgery had good swallow outcome with one operative mortality (2.6%). At the median follow-up of 61 months, overall favorable outcome was 84% after surgery and 25% for dilatation (p < 0.0001). Majority of patients with acid-induced corrosive esophageal stricture were refractory to dilatation. Esophageal dilatations were ultimately failed in three-fourth of the patients. Concomitant cricopharyngeal stricture, long stricture length, requiring frequent dilatation, and refractory to >11 mm dilatation were factors associated with failed dilatation.

Abstract
OBJECTIVE To evaluate the efficacy and safety of the endoscopic management of Zenker Diverticulum with IT-Knife 2 device. MATERIALS AND METHODS prospective and multicenter study (Edgardo Rebagliati Martins National Hospital and Golf Clinic). We included all patients with sintomatic Zenker Diverticulum that were treated with endoscopic cricopharyngeal miotomy from september 2013 until august 2016. TECHNIQUE the diverticulum septum was faced with a cap, and then it was cut by the IT-Knife 2 (ENDOCUT Q, effect 3-2-5) until its baseline. Disphagia score was compared before and 1 and 3 months after the procedure. RESULTS 20 patients were included (11 men; average age: 71 years). The median size of Zenker Diverticulum was 40.5 mm. The median duration of the cricopharyngeal miotomy was 13.75 minutes. Clinical success was 100%. There was a significative decrease (p<0.001) in the disphagia score from 2+/-0.86 before the procedure to 0.05+/-0.22 one month after it. Recurrence after 3 months was 15% and it was completely solved after a second endoscopic treatment. Niether perforation nor bleeding was reported. Two patients had pneumonia. CONCLUSION the endoscopic management of Zenker Diverticulum with IT-Knife 2 is highly effective, safe and less complex than previous technique experience.

Abstract
Radiofrequency ablation (RFA) is widely used for the eradication of dysplasia and the treatment of early stage esophageal carcinoma in patients with Barrett’s esophagus (BE). However, there are several factors, such as variation of BE epithelium (EP) thickness among individual patients and varying RFA catheter-tissue contact, which may compromise RFA efficacy. We used a high-speed optical coherence tomography (OCT) system to identify and monitor changes in the esophageal tissue architecture from RFA. Two different OCT imaging/RFA application protocols were performed using an <italic<ex vivo</italic< swine esophagus model: (1) post-RFA volumetric OCT imaging for quantitative analysis of the coagulum formation using RFA applications with different energy settings, and (2) M-mode OCT imaging for monitoring the dynamics of tissue architectural changes in real time during RFA application. Post-RFA volumetric OCT measurements showed an increase in the coagulum thickness with respect to the increasing RFA energies. Using a subset of the specimens, OCT measurements of coagulum and coagulum + residual EP thickness were shown to agree with histology, which accounted for specimen shrinkage during histological processing. In addition, we demonstrated the feasibility of OCT for real-time visualization of the architectural changes during RFA application with different energy settings. Results suggest feasibility of using OCT for RFA treatment planning and guidance.

Abstract
AIM To report about the combination and advantages of a stapler-assisted diverticulotomy performed by flexible endoscopy.
METHODS From November 2014 till December 2015 17 patients (8 female, 9 male, average age 69.8 years) with a symptomatic Zenker diverticulum (mean size 3.5 cm) were treated by inserting a new 5 mm fully rotatable surgical stapler (MicroCutter30 Xchange, Cardica Inc.) next to an ultrathin flexible endoscope through an overtube. The Patients were under conscious sedation with the head reclined in left position, the stapler placed centrally and pushed forward to the bottom of the diverticulum. The septum was divided by the staple rows under flexible endoscopic control.
RESULTS In eleven patients (64.7%) the stapler successfully divided the septum completely. Mean procedure time was 21 min, medium size of the septum was 2.8 cm (range 1.5 cm to 4 cm). In four patients the septum was shorter than 3 cm, in seven longer than 3 cm. To divide the septum, averagely 1.3 stapler cartridges were used. Two minor bleedings occurred. Major adverse events like perforation or secondary haemorrhage did not occur. After an average time of two days patients were discharged from the hospital. In 6 patients (35.3%) the stapler failed due to a thick septum or insufficient reclination of the head. Follow up endoscopy was performed after an average of two months in 9 patients; 4 patients (44.4%) were free of symptoms, 5 patients (55.6%) stated an improvement. A relapse of symptoms did not occur.
CONCLUSION Flexible endoscopic Zenker diverticulotomy by using a surgical stapler is a new, safe and efficient treatment modality. A simultaneously tissue opening and occlusion prevents major complications.

Abstract
The aim of this study is to compare endoscopic stent suture fixation with endoscopic clip attachment or the use of partially covered stents (PCS) regarding their capability to prevent stent migration during prolonged dilatation in achalasia. Large-diameter self-expanding metal stents (30 mm × 80 mm) were placed across the gastroesophageal junction in 11 patients with achalasia. Stent removal was scheduled after 4 to 7 days. To prevent stent dislocation, endoscopic clip attachment, endoscopic stent suture fixation, or PCS were used. The Eckardt score was evaluated before and 6 months after prolonged dilatation. After endoscopic stent suture fixation, no (0/4) sutured stent migrated. When endoscopic clips were used, 80% (4/5) clipped stents migrated (p = 0.02). Of two PCS (n = 2), one migrated and one became embedded leading to difficult stent removal. Technical adverse events were not seen in endoscopic stent suture fixation but were significantly correlated with the use of clips or PCS (r = 0.828, p = 0.02). Overall, 72% of patients were in remission regarding their achalasia symptoms 6 months after prolonged dilatation. Endoscopic suture fixation of esophageal stents but not clip attachment appears to be the best method of preventing early migration of esophageal stents placed at difficult locations such as at the naive gastroesophageal junction.

Abstract
BACKGROUND AND AIMS In recent years high-resolution microendoscopy (HRME) has shown potential to improve screening for esophageal squamous cell neoplasia. Furthering its utility in a clinical setting, especially in lower-resource settings, could be accomplished by reducing the size and cost of the system as well as incorporating the ability of real-time, objective feedback. This article describes a tablet-interfaced HRME with fully automated, real-time image analysis. METHODS The performance of the tablet-interfaced HRME was assessed by acquiring images from the oral mucosa in a normal volunteer. An automated, real-time analysis algorithm was developed and evaluated using training, test, and validation images from a previous in vivo study of 177 patients referred for screening or surveillance endoscopy in China. The algorithm was then implemented in a tablet HRME that was used to obtain and analyze images from esophageal tissue in 3 patients. Images were displayed alongside the probability that the imaged region was neoplastic. RESULTS The tablet-interfaced HRME demonstrated comparable imaging performance at a lower cost compared with first-generation laptop-interfaced HRME systems. In a post-hoc quantitative analysis, the algorithm identified neoplasia with a sensitivity and specificity of 95% and 91%, respectively, in the validation set compared with 84% and 95% achieved in the original study. CONCLUSIONS The tablet-based HRME is a low-cost tool that provides quantitative diagnostic information to the endoscopist in real time. This could be especially beneficial in lower-resource settings for operators with less experience interpreting HRME images.

Abstract
Barrett’s esophagus is a known precursor lesion to esophageal adenocarcinoma. In these patients, early detection of premalignant disease, known as dysplasia, allows curative minimally invasive endoscopic therapy, but is confounded by a lack of contrast in white light endoscopy. Imaging fluorescently labeled lectins applied topically to the tissue has the potential to more accurately delineate dysplasia, but tissue autofluorescence limits both sensitivity and contrast when operating in the visible region. To overcome this challenge, we synthesized near-infrared (NIR) fluorescent wheat germ agglutinin (WGA-IR800CW) and constructed a clinically translatable bimodal NIR and white light endoscope. Images of NIR and white light with a field of view of 63 deg and an image resolution of 182 μm are coregistered and the honeycomb artifact arising from the fiber bundle is removed. A minimum detectable concentration of 110 nM was determined using a dilution series of WGA-IR800CW. We demonstrated ex vivo that this system can distinguish between gastric and squamous tissue types in mouse stomachs (p=0.0005) and accurately detect WGA-IR800CW fluorescence in human esophageal resections (compared with a gold standard imaging system, rs>0.90). Based on these findings, future work will optimize the bimodal endoscopic system for clinical trials in Barrett’s surveillance.

Abstract
A modular video endoscope is developed to enable both white light imaging (WLI) and vital-dye fluorescence imaging (VFI) in a single-endoscopic insertion for the early detection of cancer in Barrett’s esophagus (BE). We demonstrate that VFI can be achieved in conjunction with white light endoscopy, where appropriate white balance is used to correct for the presence of the emission filter. In VFI mode, a contrast enhancement feature is implemented in real time to further highlight glandular patterns in BE and related malignancies without introducing artifacts. In a pilot study, we demonstrate accurate correlation of images in two widefield modalities, with representative images showing the disruption and effacement of glandular architecture associated with cancer development in BE. VFI images of these alterations exhibit enhanced contrast when compared to WLI. Results suggest that the usefulness of VFI in the detection of BE-related neoplasia should be further evaluated in future in vivo studies.

Abstract
UNLABELLED Zenker's diverticulum (ZD) is an acquired protrusion of the esophageal wall. Treatment is reservedfor symptomatic cases. In Argentina, ZD has historically managed exclusively by surgical intervention. In 1995, Ishioka, et al and Mulder, et a1published their experience using flexible endoscopes for diverticulotomy. Since then, a wide variety ofdifferent techniques have been published. Objetive. To present technique modifications and results ofour center. MATERIAL AND METHODS We reviewed the database of57patients (36 men), with a mean age of 71.9 years (range 37-98), with symptomatic Zenker ' diverticulum, who underwent endoscopic myotomy, from December 1997 to April 2015. All procedures were performed in our center, by the same endoscopist (HM). The most common symptom was dysphagia (94.7%), which was recorded by a 0-4 score (0=no dysphagia, 1 =solids, 2=semisolids, 3=liquids, 4=saliva). The first nine cases were done exposing the septum with a nasogastric tube, and the others with a soft diverticuloscope. Allprocedures were carried out with the patient under deep sedation, adminis- tered by an anesthesiologist. A myotomy was done in all cases with a needle-knife, using a coagulation current, to prevent bleeding. Clips were placed to close mucosalilaps, decrease the risk of unsuspected perforation and postprocedure bleeding. RESULTS Seventy procedures were performed, in 56 patients. One patient was excluded because of incomplete myotomy due to a severe adverse event. Ninety-eight percent ofpatients had resolution or improvement of the dysphagia score, at 30 days. Three patients with regurgitation as their sole complaint completely resolved their symptom. Median follow-up was 25 months (1-99). Thirty-seven patients were followed for at least 1 year and 97.3% showed a favorable outcome. In 13 cases (22.8%) a reintervention was needed, with positive results in all cases. Bleeding occurred in one patient (1.4%), who required surgery. Another patient required surgical intervention due to technical issues. There were no perforations or infections. CONCLUSION Treatment of ZD with flexible endoscope is a safe and effective option, with good long-term results. We need randomized clinical trials comparing different therapeutic options to be able to recommend a definitive strategy. Until then, we suggest using the technique with which each center has the most experience and feels most comfortable performing.

Abstract
This paper reports our experience with a new over-the-scope clip in the setting of recurrent bleeding and oesophageal fistula. We treated five patients with the over-the-scope Padlock Clip™. It is a nitinol ring, with six inner needles preassembled on an applicator cap, thumb press displaced by the Lock-It™ delivery system. The trigger wire is located alongside the shaft of the endoscope, and does not require the working channel. Three patients had recurrent bleeding lesions (bleeding rectal ulcer, post polypectomy delayed bleeding and duodenal Dieulafoy's lesion) and two patients had a persistent respiratory-esophageal fistula. In all patients a previous endoscopic attempt with standard techniques had been useless. All procedures were conducted under conscious sedation but for one patient that required general anaesthesia due to multiple comorbidities. We used one Padlock Clip™ for each patient in a single session. Simple suction was enough in all of our patients to obtain tissue adhesion to the instrument tip. A remarkably short application time was recorded for all cases (mean duration of the procedure: 8 min). We obtained technical and immediate clinical success for every patient. No major immediate, early or late (within 24 h, 7 d or 4 wk) adverse events were observed, over follow-up durations lasting a mean of 109.4 d. One patient, treated for duodenal bulb bleeding from a Dieulafoy's lesion, developed signs of mild pancreatitis 24 h after the procedure. The new over-the-scope Padlock Clip™ seems to be simple to use and effective in different clinical settings, particularly in "difficult" scenarios, like recurrent bleeding and respiratory-oesophageal fistulas.

Abstract
Over-the-scope clip (OTSC) system is becoming a new reliable technique which is available for the endoscopic closure of fistulas, bleeding, perforations and so on. We describe the case of a patient with a non-healing gastrocutaneous fistula after esophagectomy for esophageal squamous cell carcinoma which was successfully closed using an OTSC system. This is the first report of the use of OTSC to treat a non-healing gastrocutaneous fistula successfully after esophagectomy. We believe our experience will give such patients an ideal way to cure the fistula without suffering too much and also explore new application of OTSC.

Abstract
Esophagectomy with extended lymphadenectomy and gastric conduit reconstruction is a radical procedure for the treatment of esophageal cancer that is associated with a high morbidity rate. Gastric conduit necrosis is a fatal complication that occurs in 2% of patients. Conventionally, two-stage salvage surgery consisting of removal of the necrotic gastric conduit followed by reconstruction has been performed; however, this procedure has a high morbidity rate. We describe a 61-year-old man who underwent minimally invasive esophagectomy complicated by slowly progressive gastric conduit necrosis associated with complete neck drainage and a stable overall condition. There was a 2 cm gap in the anastomosis. Because there was no evidence of residual gastric conduit necrosis, a removable, covered self-expanding metal stent (SEMS) was inserted to bridge the anastomosis. The stent was fixed to the patient’s ear with silk thread through the lasso on its proximal end to prevent migration. Eight weeks after insertion, the stent was removed easily without any associated complications. The anastomotic defect was completely bridged with granulation tissue, showing progressive epithelialization without leakage or stenosis. The patient was discharged home in good general health. This is the first report of the successful conservative management of esophago-gastric conduit anastomosis disruption with SEMS placement.

Abstract
AIM: To investigate a newly designed stent and its dilatation effect in a rabbit model of benign esophageal stricture.
METHODS: Thirty-four New Zealand white rabbits underwent a corrosive injury in the middle esophagus for esophageal stricture formation. Thirty rabbits with a successful formation of esophageal strictures were randomly allocated into two groups. The control group (n = 15) was implanted with a conventional stent, and the study group (n = 15) was implanted with a detachable “pieced” stent. The study stent (30 mm in length, 10 mm in diameter) was composed of three covered metallic pieces connected by surgical suture lines. The stent was collapsed by pulling the suture lines out of the mesh. Two weeks after stricture formation, endoscopic placement of a conventional stent or the new stent was performed. Endoscopic extraction was carried out four weeks later. The extraction rate, ease of extraction, migration, complications, and survival were evaluated.
RESULTS: Stent migration occurred in 3/15 (20%) animals in the control group and 2/15 (13%) animals in the study group; the difference between the two groups was not statistically significant. At the end of four weeks, the remaining stents were successfully extracted with the endoscope in 100% (11/11) of the animals in the study group, and 60% (6/10) of the animals in the control group; this difference was statistically significant (P < 0.05). There was no difference in the mean number of follow-up days between the control and study groups (25.33 vs 25.85). Minor bleeding was reported in five cases in the study group and four in the control group. There were no severe complications directly associated with stent implantation or extraction in either of the two groups.
CONCLUSION: In this experimental protocol of benign esophageal strictures, the novel “pieced” stent demonstrated a superior removal rate with a similar migration rate compared to a conventional stent.

Abstract
There is substantial interest in identifying patients with premalignant conditions such as Barrett's esophagus (BE), to improve outcomes of subjects with esophageal adenocarcinoma. However, there is limited consensus on the rationale for screening, the appropriate target population, and optimal screening modality. Recent progress in the development and validation of minimally invasive tools for BE screening has reinvigorated interest in BE screening. BE risk scores combining clinical, anthropometric, and laboratory variables are being developed that may allow more precise targeting of screening to high-risk individuals. This article reviews and summarizes data on recent progress and challenges in screening for BE.

Abstract
A 57-year-old man presented to the hospital because of swallowing of a small marble precipitated by a hallucination. He subsequently developed chest discomfort. He had a history of psychiatric problem and an esophageal corrosive injury complicated by stricture of the middle esophagus.This report describes the novel idea of endoscopic intervention for the retrieval of an esophageal foreign body. Its inventiveness and the use of limited resources, by adapting a 30-mm aseptic common tubing into an endoscopic retrieving device, make the method novel. This novel low-cost endoscopic cap (NLCEC) was adapted to 25 mm of the front end of the endoscope, with 5 mm maintained for the soft part to prevent esophageal mucosal injury during the retrieval process. An 8-mm green marble was found impacted in the esophagus 32 cm from the incisors. The use of forced suction allowed for the successful retrieval of the marble within minutes. The patient had an uneventful recovery without any serious complications.This NLCEC may be a viable and safe tool for the endoscopic retrieval of esophageal foreign objects without general anesthesia. This innovative design is beneficial in terms of patient safety, easy preparation, and low cost.

Abstract
Current imaging tools are associated with inconsistent sensitivity and specificity for detection of Barrett's-associated neoplasia. Optical imaging has shown promise in improving the classification of neoplasia in vivo. The goal of this pilot study was to evaluate whether in vivo vital dye fluorescence imaging (VFI) has the potential to improve the accuracy of early-detection of Barrett's-associated neoplasia. In vivo endoscopic VFI images were collected from 65 sites in 14 patients with confirmed Barrett's esophagus (BE), dysplasia, oresophageal adenocarcinoma using a modular video endoscope and a high-resolution microendoscope(HRME). Qualitative image features were compared to histology; VFI and HRME images show changes in glandular structure associated with neoplastic progression. Quantitative image features in VFI images were identified for objective image classification of metaplasia and neoplasia, and a diagnostic algorithm was developed using leave-one-out cross validation. Three image features extracted from VFI images were used to classify tissue as neoplastic or not with a sensitivity of 87.8% and a specificity of 77.6% (AUC = 0.878). A multimodal approach incorporating VFI and HRME imaging can delineate epithelial changes present in Barrett's-associated neoplasia. Quantitative analysis of VFI images may provide a means for objective interpretation of BE during surveillance.

Abstract
BACKGROUND The purpose of this study was to compare the upper gastrointestinal endoscope (UGE) insertion-mediated cuff pressure increase between a tracheal tube with a tapered cuff (Taper) and or conventional high volume low pressure cuff (HVLP) utilizing a porcine larynx model. METHODS The automated cuff pressure was adjusted to 10, 20, and 30 cmH2O. The Taper and HVLP cuff pressure increases by UGE insertion were measured. RESULTS Significant cuff pressure increase was observed by UGE insertion regardless of initial cuff pressure. The cuff pressure of the Taper was significantly lower than that of the HVLP by UGE insertion. CONCLUSIONS These findings suggest that the Taper may be more effective than the HVLP in preventing tracheal tube cuff increase by UGE insertion.

Abstract
AIM: To undertake a randomised pilot study comparing biodegradable stents and endoscopic dilatation in patients with strictures.
METHODS: This British multi-site study recruited seventeen symptomatic adult patients with refractory strictures. Patients were randomised using a multicentre, blinded assessor design, comparing a biodegradable stent (BS) with endoscopic dilatation (ED). The primary endpoint was the average dysphagia score during the first 6 mo. Secondary endpoints included repeat endoscopic procedures, quality of life, and adverse events. Secondary analysis included follow-up to 12 mo. Sensitivity analyses explored alternative estimation methods for dysphagia and multiple imputation of missing values. Nonparametric tests were used.
RESULTS: Although both groups improved, the average dysphagia scores for patients receiving stents were higher after 6 mo: BS-ED 1.17 (95%CI: 0.63-1.78) P = 0.029. The finding was robust under different estimation methods. Use of additional endoscopic procedures and quality of life (QALY) estimates were similar for BS and ED patients at 6 and 12 mo. Concomitant use of gastrointestinal prescribed medication was greater in the stent group (BS 5.1, ED 2.0 prescriptions; P < 0.001), as were related adverse events (BS 1.4, ED 0.0 events; P = 0.024). Groups were comparable at baseline and findings were statistically significant but numbers were small due to under-recruitment. The oesophageal tract has somatic sensitivity and the process of the stent dissolving, possibly unevenly, might promote discomfort or reflux.
CONCLUSION: Stenting was associated with greater dysphagia, co-medication and adverse events. Rigorously conducted and adequately powered trials are needed before widespread adoption of this technology.

Abstract
BACKGROUND Dual-Knife(®) (Olympus) and Hydride-Knife(®) are new needle knives frequently used for submucosal dissection because of their safety and precision. In this study we aimed to evaluate the efficacy and safety of such devices in the diverticulopexy by flexible endoscopy. METHODS From February 2009 to March 2013, 42 patients (25 men), mean age 74.5, with symptomatic Zenker's diverticulum, were included in a non-randomized prospective multicenter study. The symptoms described by all patients include dysphagia, regurgitation and/or swallowing disorders. The diverticulopexy was performed with the Dual-Knife(®) or Hydrid-Knife(®), after septum exposure with the diverticuloscope, and terminated with distal tip clips positioning. All complications were noted. Patients' symptoms were regularly assessed during follow-up visits or telephone interviews. RESULTS The first endoscopy treatment was successful for all patients. Thirty-seven patients (88%) had symptoms improvement after the first treatment. The recurrence rate was 14% (6 patients); a second endoscopic treatment was required 12 months on average after the first treatment, with 100% efficiency. Mid-term (16 months) efficiency was 91.67% after 1 to 3 endoscopic treatments. A total of 55 procedures were performed without perforation or significant bleeding and 3 patients underwent surgery. In multivariate analysis, the diverticulum size and the type of dissection knife were not risks factors for recurrence. CONCLUSIONS Endoscopic diverticuloscope-assisted diverticulotomy with submucosal dissection knives is a safe and effective alternative treatment for patients with a symptomatic Zenker's diverticulum measuring between 2 and 10 cm.

Abstract
BACKGROUND Capsule endoscopy has been proposed as an alternative to fibreoptic endoscopy for oesophageal varices evaluation in cirrhotics. However, it shows only moderate sensitivity compared to fibreoptic endoscopy. AIM To compare post-meal capsule endoscopy to fibreoptic endoscopy, based on the hypothesis that meal-induced increase of portal pressure can enhance its sensitivity. METHODS Twenty-five patients were submitted to fibreoptic endoscopy and, after a standard meal, capsule endoscopy. RESULTS Post-meal capsule endoscopy detected varices in the 18 patients in whom fibreoptic endoscopy detected varices plus 3 more subjects (sensitivity 100%, specificity 70%); large varices in the 4 patients in whom fibreoptic endoscopy graded varices as large, plus 5 more subjects; red markers in the 5 patients in whom fibreoptic endoscopy detected red markers, plus 3 more subjects. High-risk varices were identified in 11 patients by post-meal capsule endoscopy and in 10 by fibreoptic endoscopy (sensitivity 100%, specificity 93.8%). CONCLUSIONS Post-meal capsule endoscopy identified more varices, large varices and red markers than fibreoptic endoscopy. The two methods detected similar proportions of high-risk varices. These data suggest that a standard meal can enhance the sensitivity of capsule endoscopy in the detection and grading of oesophageal varices in cirrhotics.

Abstract
Image diagnoses for esophageal cancer are progressing. With regard to endoscopic examination, chrome endoscopy using iodine have been performed so far to identify the range of lesion and to detect multiple primary cancers. In addition to that, endoscopic ultrasonography is used to diagnose the depth of tumor invasion and to identify lymph node metastasis. Recently, image-enhanced endoscopy (IEE) [e.g. Flexible spectral Imaging Color Enhancement (FICE), i-scan, Narrow Band Imaging (NBI), Autofluorescence imaging (AFI)] has developed. IEE is useful to detect superficial lesion, and is being utilized for diagnosing the tumor depth of invasion by using magnifying endoscopy( ME) together. In this literature, recent progress of endoscopic diagnosis, especially about IEE and ME, is reviewed. In addition to that, a way of endoscopic examination using IEE and ME is introduced.
