Abstract
PURPOSE OF REVIEW Endoscopic cryotherapy has emerged as a minimally invasive procedure for targeted tissue ablation within the gastrointestinal tract. This review aims to provide a comprehensive overview of current clinical applications of EC with a review of the pertinent literature. RECENT FINDINGS Endoscopic cryotherapy has demonstrated safety and efficacy for various gastrointestinal conditions. Recent studies have highlighted the efficacy of endoscopic cryotherapy, including both liquid nitrogen-based spray cryotherapy and the novel cryoballoon focal ablation system, in achieving complete eradication of dysplasia and neoplasia in Barrett's esophagus. Endoscopic cryotherapy has also shown promise as a second-line treatment option for patients with dysplastic Barrett's esophagus refractory to radiofrequency ablation and as an alternative to surgical resection for duodenal adenomas, when endoscopic resection is not feasible. Innovative applications for the treatment of gastrointestinal bleeding and management of benign refractory esophageal strictures have also been reported. SUMMARY Endoscopic cryotherapy represents a safe, effective, and well tolerated therapeutic option for various clinical scenarios in gastrointestinal endoscopy, including challenging disease states such as refractory Barrett's esophagus and advanced esophageal cancer. Advancements in cryotherapy technology and ongoing research continue to explore additional clinical indications and expand the role of endoscopic cryotherapy in patient care with an aim toward improved patient outcomes.

Efficacy and Safety of Cryoablation in Barrett's Esophagus and Comparison with Radiofrequency Ablation: A Meta-Analysis. Cancers (Basel) 2024; 16:2937. [PMID: 39272792 PMCID: PMC11394299 DOI: 10.3390/cancers16172937] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2024] [Revised: 08/12/2024] [Accepted: 08/22/2024] [Indexed: 09/15/2024] Open
Abstract
BACKGROUND The mainstay approach in endoscopic eradication therapy (EET) for dysplastic Barrett's esophagus (BE) includes the endoscopic resection of visible lesions, accompanied by ablation of the residual metaplastic epithelium. Cryoablation therapy is one such emerging ablation technique in this field. This systematic review with a meta-analysis aims to accumulate pooled data on cryoablation performance in the treatment of patients with BE and to compare this technique to the standard of care radiofrequency ablation (RFA). METHODS The MEDLINE, Cochrane, and Scopus databases were searched until June 2024 for studies evaluating BE management using cryoablation for cumulative results. The primary outcome was the complete eradication of dysplasia (CED) and intestinal metaplasia (CEIM) in BE compared to RFA, while secondary outcomes included the respective pooled rates using cryoablation, recurrence, and adverse events, with a separate analysis for strictures. The meta-analyses were based on a random-effects model, and the results were reported as odds ratios (ORs) with 95% confidence intervals (CIs). Subgroup analyses by type of cryoablation were also performed. RESULTS Twenty-three studies (1604 patients) were finally included, four of which were comparative. CED and CEIM did not differ significantly between cryoablation and RFA [OR= 0.95 (95%CI: 0.50-1.81) and OR = 0.57 (95%CI: 0.20-1.63), respectively)]. The pooled rates of CED, CEIM, and recurrence after cryoablation were 84.2% (95%CI: 79.1-89.3), 64.1% (95%CI: 49.2-79.0), and 8.3% (95%CI: 4.7-11.9), accompanied by high rates of heterogeneity. Adverse events were noted in 14.5% (95%CI: 9.9-19.2) of cases, and 6.5% (95%CI: 4.1-9.0) developed strictures. In the subgroup analysis, the cryoballoon achieved a reduction in heterogeneity in CED, adverse events, and stricture formation, whereas spray catheters provided homogenous results in terms of recurrence. CONCLUSIONS Cryoablation provides equal outcomes compared to RFA in the treatment of patients with BE, with the cryoballoon achieving relatively homogenous rates of CED and adverse events.

Abstract
BACKGROUND/AIMS Radiofrequency ablation (RFA) is the first-line therapy for dysplastic Barrett's esophagus (BE). Therefore, cryotherapy has emerged as an alternative treatment option. This study aimed to compare the efficacies of these two techniques based on the rates of complete eradication of intestinal metaplasia (CE-IM) and dysplasia (CE-D). Adverse events and recurrence have also been reported. METHODS An electronic search was conducted using the Medline (PubMed), Embase, LILACS, and Google Scholar databases until December 2022. Studies were included comparing cryotherapy and RFA for treating dysplastic BE with or without early esophageal neoplasia. This study was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. RESULTS Three retrospective cohort studies involving 627 patients were included. Of these, 399 patients underwent RFA, and 228 were treated with cryotherapy. There was no difference in CE-IM (risk difference [RD], -0.03; 95% confidence interval [CI], -0.25 to 0.19; p=0.78; I2=86%) as well as in CE-D (RD, -0.03; 95% CI, -0.15 to 0.09; p=0.64; I2=70%) between the groups. The absolute number of adverse events was low, and there was no difference in the recurrence rate. CONCLUSION Cryotherapy and RFA were equally effective in treating dysplastic BE, with or without early esophageal neoplasia.

Abstract
Esophagectomy is the proposed standard of care for resectable primary esophageal cancers and recurrent lesions in the reconstructed gastric tube (GT); however, it carries significant morbidity and mortality. Endoscopic submucosal dissection (ESD) has established its role in the management of primary esophageal cancers with growing evidence of its safety in resecting recurrent primary lesions in GT. Our study aims to evaluate the safety and efficacy of ESD in the management of recurrent, localized primary esophageal cancers in GT. We searched PubMed, CENTRAL, EMBASE, Scopus, and clinical trial registries from inception to March 2023 for articles evaluating the safety and efficacy of ESD in the management of recurrent cancerous lesions in GT. Our primary outcome was the en bloc resection rate. Secondary outcomes were curative resection rate, complete resection rate, intra-procedural complication rate, post-procedure complication rate, and five-year survival rate. Seven studies with a total of 165 patients undergoing 192 ESDs were included in the review. The pooled en bloc resection rate was 92.5% (95% CI: 87.7-95.6), which was reported in all seven studies. Pooled complete resection rate was 78.9% (95% CI: 64.5-88.5) per three studies, pooled curative resection rate was 73.9% (95% CI: 63.5-82.2) per four studies, and pooled intra-procedural complication rate was 10.2% (95% CI: 1.5-46.3), which was reported in four studies. Only three studies reported a five-year survival rate that was 65.5% (95% CI: 56.0-73.9). ESD is safe and efficacious in the management of GT cancer after esophagectomy.

Abstract
Nonthermal irreversible electroporation (NTIRE) is emerging as a promising tissue ablation technique. However, maintaining irreversible electroporation (IRE) electrodes against displacement during strong esophageal spasms remains an obstacle. The present study aimed to evaluate the efficacy and safety of newly designed balloon-type endoscopic IRE catheters. Six pigs were randomly allocated to each catheter group, and each pig was subjected to four ablations at alternating voltages of 1500 V and 2000 V. Esophagogastroscopy was performed during the IRE. The ability of balloon-type catheters to execute complete IRE with 40 pulses was assessed. The success rate was higher for the balloon-type catheter than that for the basket-type (12/12 [100%] vs. 2/12 [16.7%], p < 0.001). Following gross inspection and histologic analysis of the 1500-V vs. 2000-V balloon-type catheter revealed a larger mucosal damage area (105.3 mm2 vs. 140.8 mm2, p = 0.004) and greater damage depth (476 μm vs. 900 μm, p = 0.02). Histopathology of the ablated tissue revealed separated epithelium, inflamed lamina propria, congested muscularis mucosa, necrotized submucosa, and disorganized muscularis propria. Balloon-type catheters demonstrated efficacy, achieving full electrical pulse sequences under NTIRE conditions, and a safe histological profile below 2000 V (1274 V/cm). Optimal electrical conditions and electrode arrays pose ongoing challenges.

Abstract
Over the last two decades, endoscopic eradication therapy has been established as the therapeutic strategy of choice for patients with Barrett's oesophagus-related dysplasia and early oesophageal adenocarcinoma. With a multimodal approach, ablative therapies have been highly effective in achieving remarkable eradication rates of metaplastic epithelium with an acceptable adverse event rate. Among ablative techniques, radiofrequency ablation is currently considered as the first-line option as its efficacy and safety are strongly supported by relevant data. Nevertheless, radiofrequency ablation is costly, and not universally available, or applicable to every situation. Moreover, primary failure and recurrence rates are not negligible. In the last few years, cryotherapy techniques and hybrid argon plasma coagulation have been increasingly assessed as potential novel ablative therapies. Preliminary data have been promising and suggest that they may even have a role as first-line options, alternatively to radiofrequency ablation. The aim of this review is to provide a practical guide for the ablation of Barrett's oesophagus, with emphasis on the different ablative options.

Comparison of focal cryoballoon ablation with 10- and 8-second doses for treatment of Barrett's esophagus-related neoplasia: results from a prospective European multicenter study (with video). Gastrointest Endosc 2022; 96:743-751.e4. [PMID: 35724692 DOI: 10.1016/j.gie.2022.06.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/15/2022] [Revised: 04/26/2022] [Accepted: 06/08/2022] [Indexed: 12/11/2022]
Abstract
BACKGROUND AND AIMS Focal cryoballoon ablation (FCBA) is currently being investigated for the treatment of Barrett's esophagus (BE)-related neoplasia in a European multicenter study (Euro-Coldplay study). After inclusion of 28 of 107 patients, the initial dose of 10 seconds was lowered to 8 seconds. The current study aimed to compare the efficacy and safety of a single FCBA treatment session with 10 seconds versus 8 seconds. METHODS Treatments were performed at 7 European BE referral centers. All 28 patients treated with 10 seconds were compared with 28 consecutive patients treated with 8 seconds. The gastroesophageal junction was ablated circumferentially followed by all visible BE. To assess efficacy and safety, 3 expert adjudicators, blinded to physician and dose, compared pre- and post-treatment images. Primary outcomes were median BE surface regression and stricture rate after single-session FCBA. RESULTS We included 56 patients (10-second cohort, n = 28; 8-second cohort, n = 28) with a median BE length of C0M2 (Prague classification). Baseline characteristics did not significantly differ between the cohorts. The median BE surface regression after a single FCBA session was comparable for 10 seconds and 8 seconds (80% [95% confidence interval {CI}, 75-90] and 80% [95% CI, 66-90], respectively; P = .65). Strictures requiring dilation were seen in 19% (95% CI, 4-33) and 15% (95% CI, 4-30) of the 10-second and 8-second groups, respectively (P = 1.00). Two patients in the 10-second group developed a severe stricture requiring >3 dilations. CONCLUSIONS In patients with limited BE, single-session FCBA with 8 seconds showed similar BE surface regression as compared with 10 seconds and may theoretically result in fewer and less severe strictures. Therefore, we suggest using 8 seconds as the standard dose for FCBA. (Clinical trial registration number: NL7253.).

Abstract
BACKGROUND Several techniques exist for the eradication of Barrett's esophagus (BE); however, all have limitations regarding successful conversion to squamous epithelium and a complication profile. We aimed to assess the feasibility and safety of a new nonthermal device, the EndoRotor, for the eradication of BE as a first-line ablation technique. METHODS Patients with BE were prospectively included at two tertiary referral centers in The Netherlands. INCLUSION CRITERIA BE length 2-5 cm, with low grade dysplasia, high grade dysplasia, or residual BE after endoscopic resection (ER) of a lesion containing early neoplasia. EXCLUSION CRITERIA previous ER > 50 % circumference, or previous ablation therapy. Follow-up endoscopy was performed 3 months after ablation therapy. Outcomes were the percentage of endoscopically visible BE surface regression and complications. RESULTS 30 patients were included (age 66 years, interquartile range [IQR] 59-73, median BE C0M3, 25 male). Overall, 18 patients underwent ER prior to ablation. Median percentage BE ablated was 100 % (IQR 94 %-100 %). Median visual BE surface regression at 3-month follow-up was 80 % (IQR 68 %-95 %). Multiple residual Barrett's islands were commonly seen. Six patients (20 %) had a treatment-related complication requiring intervention, including one perforation (3 %), one postprocedural hemorrhage (3 %), and four strictures (13 %). Post-procedural pain was reported in 18 patients (60 %). CONCLUSIONS Endoscopic ablation of BE using this novel nonthermal device was found to be technically demanding, with a longer procedure time compared with established ablation techniques and a high complication rate. Based on these results, we do not recommend its use as a first-line ablation technique for the eradication of BE.

Abstract
BACKGROUND AND AIMS Strong evidence supports the use of radiofrequency ablation (RFA) in the management of dysplastic/neoplastic Barrett's esophagus (BE). Recently, the efficacy of the cryoballoon ablation (CBA) system was demonstrated in multicenter cohort studies. We aimed to assess the comparative effectiveness and safety of these 2 ablation modalities for endoscopic eradication therapy (EET) in a cohort study. METHODS Data were abstracted on patients with dysplastic BE or intramucosal carcinoma undergoing EET using RFA or CBA as the primary ablation modality at 2 referral centers. The primary outcome was the rate of complete remission intestinal metaplasia (CRIM). Secondary outcomes were rates of complete remission of dysplasia (CRD) and adverse events. Cox proportional hazards models and propensity scored-matched analyses were conducted to compare outcomes. RESULTS Three hundred eleven patients (CBA, 85 patients; RFA, 226 patients) with a median follow-up of 1.5 years (interquartile range, .8, 2.5) in the RFA group and 2.0 years (interquartile range, 1.3, 2.5) in the CBA group were studied. On multivariable analyses, the chances of reaching CRD and CRIM were not influenced by ablation modality. Propensity score-matched analysis revealed a comparable chance of achieving CRIM (CBA vs RFA: hazard ratio, 1.24; 95% confidence interval, .79-1.96; P = .35) and CRD (CBA vs RFA: hazard ratio, 1.19; 95% confidence interval, .82-1.73; P = .36). The CBA group had a higher stricture rate compared with the RFA group (10.4% vs 4.4%, P = .04). CONCLUSIONS Histologic outcomes of EET using CBA and RFA for dysplastic BE appear to be comparable. A randomized trial is needed to definitively compare outcomes between these 2 modalities.

Abstract
BACKGROUND The novel 180° cryoballoon (CbAS180) enables semicircumferential treatment over a length of 3 cm per application. This first-in-human study evaluates its feasibility, efficacy, and safety for the treatment of Barrett's esophagus (BE) neoplasia. METHODS This multicenter study consisted of dose-finding and extension phases. Dose-finding started with the lowest dose possible (1.0 mm/s). For each dose, six patients were treated circumferentially over a 3-cm length. The dose was increased until the median BE regression was ≥ 60 % without serious adverse events (SAEs). In the extension phase, the dose was confirmed in 19 new patients. The outcomes were technical success, BE regression after one treatment, and SAEs. RESULTS 25 patients (median Prague C0M3) were included (6 dose-finding/19 extension). In two patients, the CbAS180 could not be applied because of unstable balloon positioning. The technical success rate was 96 % (22 /23). In the six dose-finding patients, the starting dose resulted in median BE regression of 94 % (95 % confidence interval [CI] 60 %-97 %) without SAEs and was thus considered effective. Overall median BE regression was 80 % (95 %CI 60 %-90 %). CONCLUSION Single-session CbAS180 seems feasible, safe, and effective, and is a promising technique for the treatment of patients with BE neoplasia.

Abstract
Barrett's esophagus (BE) is the precursor lesion for esophageal adenocarcinoma (EAC) development. Unfortunately, BE screening/surveillance has not provided the anticipated EAC reduction benefit. Noninvasive techniques are increasingly available or undergoing testing to screen for BE among those with/without known risk factors, and the use of artificial intelligence platforms to aid endoscopic screening and surveillance will likely become routine, minimizing missed cases or lesions. Management of high-grade dysplasia and intramucosal EAC is clear with endoscopic eradication therapy preferred to surgery. BE with low-grade dysplasia can be managed with removal of visible lesions combined with endoscopic eradication therapy or endoscopic surveillance at present.

Abstract
The management of Barrett's esophagus (BE) has evolved as newer technologies and novel methods are developed. Endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD) are the initial interventions of choice for nodular BE, with ESD reserved for endoscopists highly trained in the technique and for larger lesions that would warrant en bloc resection. Resection should then be followed by ablative therapy, which remains first line in the treatment of BE with dysplasia. Although there is a myriad of ablation techniques available to the endoscopist, this review has found that radiofrequency ablation (RFA) continues to have the most robust safety and efficacy data to support its use despite a relatively high rate of recurrence. Cryotherapy and Hybrid-APC appear to be safe and effective as RFA alternatives, but further trials are still needed to directly compare their outcomes to RFA and ultimately guide changes in treatment decisions.

Abstract
Barrett’s esophagus is the condition in which a metaplastic columnar epithelium
replaces the stratified squamous epithelium that normally lines the distal
esophagus. The condition develops as a consequence of chronic gastroesophageal
reflux disease and predisposes the patient to the development of esophageal
adenocarcinoma. The diagnosis and management of Barrett’s esophagus have
undergone dramatic changes over the years and continue to evolve today.
Endoscopic eradication therapy has revolutionized the management of dysplastic
Barrett’s esophagus and early esophageal adenocarcinoma by significantly
reducing the morbidity and mortality associated with the prior gold standard of
therapy, esophagectomy. The purpose of this review is to highlight current
principles in the management and endoscopic treatment of this disease.

Abstract
Barrett's esophagus (BE) is a precursor to esophageal adenocarcinoma and current practice is to establish endoscopic surveillance once diagnosed, in order to identify early dysplasia and neoplasia that has the potential to undergo endoscopic eradication therapy (EET). Before embarking upon EET the clinical team has a duty to consider all viable options and come to a plan based on recent evidence. The therapeutic approach varies greatly but largely adheres to the mantra of 'Detect-Resect-Ablate', in which high-quality endoscopy identifies BE associated pathology, associated lesions (if present) undergo safe endoscopic resection and remaining intestinal metaplasia in the esophagus is ablated to prevent recurrence of dysplasia. In this review, current practice, pitfalls, complications, and the future perspectives on practice in this field are discussed. The Western perspective is focused on here, with an outline of the differences in clinical practice with Asian nations and attempts to bridge these differences.

Abstract
The incidence of esophageal cancer (EC) is on the rise. With the distinct subtypes of adenocarcinoma and squamous cell carcinoma comes specific risk factors, and as a result, people of certain regions of the world can be more prone to a subtype. For example, squamous cell carcinoma of the esophagus has the highest incidence in eastern Africa and eastern Asia, with smoking being a major risk factor, whereas adenocarcinoma is more prevalent in North America and western Europe, with gastroesophageal reflux disease being a leading risk factor. With that being said, adenocarcinoma and squamous cell carcinoma have similar and unfortunately poor survival rates, partly because EC is prone to early metastasis given that the esophagus does not have a serosa, as well as the superficial nature of its lymphatics compared with the rest of the gastrointestinal tract. This makes early detection of the utmost importance, and certain patients have been shown to have the benefit of screening/surveillance endoscopies, including those with Barrett's esophagus, lye-induced/caustic strictures, tylosis, and Peutz-Jeghers syndrome. Until treatments significantly improve, identifying EC at the earliest stage will have the best success for patient outcomes, and further elucidation of its pathogenesis and risk factors may lead to identifying other high-risk groups that should be screened.

Abstract
BACKGROUND AND AIMS EMR is the preferred endoscopic therapy for duodenal adenomas (DAs) but is associated with an overall adverse event rate of 26%. Cryotherapy using a Cryoballoon Focal Ablation System (CbFAS) can safely and effectively eradicate esophageal intestinal metaplasia. We report our first experience with cryoballoon ablation for treatment of flat DAs. METHODS This was an American, multicenter, retrospective study involving 5 centers. DAs (Paris 0-IIa and 0-IIb) were treated with nitrous oxide for 5 to 12 seconds using CbFAS. Follow-up EGD was performed at 3 to 12 months. RESULTS Seventeen DAs (mean size, 22.7 ± 14.3 mm; 12 tubular, 5 tubulovillous) from 13 patients (mean age, 66.5 ± 9.99 years; 61.5% males) were included in the study. Thirteen of 17 DAs (76.5%) had failed previous treatment, and 4 of 17 (23.5%) were treatment naÏve. All procedures were technically successful and achieved a >50% decrease in size after cryoballoon ablation There was no increase in size or progression of disease for any lesions. Overall, treatment was completed in 15 of 17 patients, and recurrence-free survival was achieved in 12 of 17 (71%) after a median follow-up of 15.5 months (interquartile range [IQR], 6.8-19.4). The median cryoablation time per polyp was 4 minutes (IQR, 1-7.5 minutes), and the median total procedure time was 25 minutes (IQR, 22-30.5 minutes). There were no intra- or postprocedural adverse events. CONCLUSIONS Nitrous oxide cryoballoon ablation of nonpolypoid DAs is feasible, with promising safety and efficacy.

Abstract
Cryotherapy is an ablation modality relying on freeze-thaw cycles to promote cell death through intracellular ice crystal formation, ischemia, and apoptosis. Currently, 2 different cryotherapy systems are available for esophageal use. The first is cryospray ablation, which involves repetitive applications of liquid nitrogen. The second system, cryoballoon ablation, freezes the esophageal mucosa with liquid nitrous oxide using a compliant balloon. To date, studies have shown that cryotherapy is an effective and safe method for eradicating Barrett's esophagus; however, larger prospective series with longer follow-up are warranted to determine the clinical utility of cryotherapy in the treatment of Barrett's esophagus.

Abstract
INTRODUCTION Cryotherapy is a cold-based ablative therapy used primarily as second line therapy in patients with Barrett's esophagus (BE) who have persistent dysplasia after undergoing endoscopic treatment with radiofrequency ablation (RFA). Few studies have described the use of cryotherapy as a primary treatment modality for dysplastic or neoplastic BE. AIM To evaluate the efficacy of cryotherapy as primary treatment of dysplastic and/or neoplastic BE by conducting a systemic review and meta-analysis. METHODS A systematic search of Medline, Embase, and Web of Science was performed from January 2000 through March 2020. Articles included were observational studies and clinical trials which included patients who had biopsy confirmed dysplastic or neoplastic BE (i.e., high grade dysplasia (HGD), low grade dysplasia (LGD) or intramucosal adenocarcinoma (ImCA)), underwent ≥1 session of cryotherapy, and had a follow-up endoscopy. Primary outcomes were pooled proportions of patients achieving complete eradication of dysplasia (CE-D) and/or intestinal metaplasia (CE-IM) by using a random effects model. RESULTS Fourteen studies making up 405 patients with follow-up ranging from 3-54 months were included. In 13 studies, a total of 321/405 patients achieved CE-D with a pooled proportion of 84.8% (95% confidence interval [CI] 72.2-94.4), with substantial heterogeneity (I2 = 88.3%). In 13 studies, a total of 321/405 patients achieved CE-D with a pooled proportion of 84.8% (95% confidence interval [CI] 72.2-94.4), with substantial heterogeneity (I2 = 88.3%). Subgroup analysis of only high-quality studies revealed a pooled proportion of CE-D 91.3% (95% CI, 83.0-97.4, I2 = 69.5%) and pooled proportion of CE-IM of 71.6% (95% CI, 59.0-82.9, I2 = 80.9%). Adverse events were reported in 12.2% patients. CONCLUSION Cryotherapy is a safe and effective primary therapy for dysplastic/early neoplastic BE. CE-D and CE-IM rates are comparable to those for other ablation modalities, including RFA. Cryotherapy should be considered for primary therapy of dysplastic BE and early esophageal neoplasia.

Abstract
PURPOSE OF REVIEW Barrett's esophagus (BE) is the only known precursor to esophageal adenocarcinoma (EAC), a cancer associated with increasing incidence and poor survival. Early identification and effective treatment of BE-related neoplasia prior to the development of invasive adenocarcinoma are essential to limiting the morbidity and mortality associated with this cancer. In this review, we summarized the recent evidence guiding endoscopic eradication therapies (EET) for neoplastic BE. RECENT FINDINGS New sampling technologies and the application of artificial intelligence (AI) systems have potential to revolutionize early neoplasia detection in BE. EET for BE are safe and effective in achieving complete eradication of intestinal metaplasia (CE-IM) and reducing the progression to EAC, a practice endorsed by all GI society guidelines. EET should be considered in patients with high-grade dysplasia (HGD), intramucosal carcinoma (IMC), and select cases with low-grade dysplasia (LGD). The increasing use of endoscopic submucosal dissection (ESD) in the West may allow EET of select cases with submucosal EAC. Post-EET surveillance strategies will continue to evolve as knowledge of specific risk factors and long-term neoplasia recurrence rates improve. In the last decade, major advancements in EET for neoplastic BE have been achieved. These now represent the standard of care in the management of BE-related dysplasia and intramucosal cancer.

Abstract
INTRODUCTION Ablation of Barrett's esophagus (BE) is the preferred approach for the treatment of neoplasia without visible lesions. Limited data on cryoballoon ablation (CBA) suggest its potential clinical utility. We evaluated the safety and efficacy of CBA in a multicenter study of patients with neoplastic BE. METHODS In a prospective clinical trial, 11 academic and community centers recruited consecutive patients with BE of 1-6 cm length and low-grade dysplasia, high-grade dysplasia (HGD), or intramucosal adenocarcinoma (ImCA) confirmed by central pathology. Patients with symptomatic pre-existing strictures or visible BE lesions had dilation or endoscopic mucosal resection (EMR), respectively, before enrollment. A nitrous oxide cryoballoon focal ablation system was used to treat all visible columnar mucosa in up to 5 sessions. Study end points included complete eradication of all dysplasia (CE-D) and intestinal metaplasia (CE-IM) at 1 year. RESULTS One hundred twenty patients with BE with ImCA (20%), HGD (56%), or low-grade dysplasia (23%) were enrolled. In the intention-to-treat analysis, the CE-D and CE-IM rates were 76% and 72%, respectively. In the per-protocol analysis (94 patients), the CE-D and CE-IM rates were 97% and 91%, respectively. Postablation pain was mild and short lived. Fifteen subjects (12.5%) developed strictures requiring dilation. One patient (0.8%) with HGD progressed to ImCA, which was successfully treated with EMR. Another patient (0.8%) developed gastrointestinal bleeding associated with clopidogrel use. One patient (0.8%) had buried BE with HGD in 1 biopsy, not confirmed by subsequent EMR. DISCUSSION In patients with neoplastic BE, CBA was safe and effective. Head-to-head comparisons between CBA and other ablation modalities are warranted (clinicaltrials.gov registration NCT02514525).

Single-Step Treatment with Limited Endoscopic Resection and Cryoballoon Ablation Is Feasible and Safe in an Esophageal Porcine Model. Dig Dis Sci 2020; 65:3175-3183. [PMID: 31970611 DOI: 10.1007/s10620-020-06054-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/14/2019] [Accepted: 01/06/2020] [Indexed: 12/09/2022]
Abstract
BACKGROUND Treatment of Barrett's neoplasia consists of two steps: endoscopic resection of visible lesions with subsequent ablation of remaining Barrett's epithelium. However, extensive resection might hamper subsequent ablation due to stenosis. Combining both modalities in one session therefore offers potential advantages. Single-step treatment with radiofrequency ablation and resection appeared to be unsafe. AIMS To evaluate feasibility and safety of single-step treatment with cryoballoon ablation and endoscopic resection. METHODS Two single-step treatment regimens (15 treatment areas per regimen) were evaluated: (1) CRYO-EMR: four side-by-side focal ablations of 10 seconds followed by resection in the treated area; (2) EMR-CRYO: resection followed by 10-s ablation targeted on the resection wound. Primary outcome for both regimens was safety (perforations, clinically relevant strictures) and for CRYO-EMR also feasibility of resection and histopathological evaluation. Secondly, all CRYO-EMR and esophageal resection specimens were histopathologically evaluated. RESULTS Six female pigs were treated (five treatment areas per animal). During 28 days of follow-up, no perforations or clinically relevant stenosis occurred. All resections were technically successful. For all CRYO-EMR specimens, histopathological evaluation was feasible with ablation effects present throughout all layers, while the architecture requisite for histopathological analysis remained intact. After 28 days, histopathological evaluation of the esophagi was performed. For EMR-CRYO, post-treatment fibrosis was present throughout the submucosa. The muscularis propria was the deepest layer involved for CRYO-EMR. CONCLUSIONS Single-step treatment with limited endoscopic resection and cryoballoon ablation is feasible and safe in a porcine model and justifies further evaluation in a clinical trial.

Abstract
PURPOSE OF REVIEW Barrett's oesophagus is the only identifiable precursor lesion to oesophageal adenocarcinoma. The stepwise progression of Barrett's oesophagus to dysplasia and invasive carcinoma provides the opportunity to intervene and reduce the morbidity and mortality associated with this lethal cancer. Several studies have demonstrated the efficacy and safety of endoscopic eradication therapy (EET) for the management of Barrett's oesophagus related neoplasia. The primary goal of EET is to achieve complete eradication of intestinal metaplasia (CE-IM) followed by enrolment of patients in surveillance protocols to detect recurrence of Barrett's oesophagus and Barrett's oesophagus related neoplasia. RECENT FINDINGS EET depends on early and accurate detection and diagnosis of Barrett's oesophagus related neoplasia. All visible lesions should be resected followed by ablation of the remaining Barrett's epithelium. After treatment, patients should be enrolled in endoscopic surveillance programmes. For nondysplastic Barrett's oesophagus, surveillance alone is recommended. For low-grade dysplasia, both surveillance and ablation are reasonable options and should be decided on an individual basis according to patient risk factors and preferences. EET is preferred for high-grade dysplasia and intramucosal carcinoma. For T1b oesophageal adenocarcinoma, esophagectomy remains the standard of care, but endoscopic therapy can be considered in select cases. SUMMARY EET is now standard of care and endorsed by societal guidelines for the treatment of Barrett's oesophagus related neoplasia. Future studies should focus on risk stratification models using a combination of clinical data and biomarkers to identify ideal candidates for EET, and to predict recurrence. Optimal therapy for T1b cancer and surveillance strategy after CE-IM are topics that require further study.

Abstract
Background and study aims Cryoablation with the Cryoballoon device is a novel ablative therapy that uses cycles of freezing and thawing to induce cell death. This single-center prospective study evaluated the feasibility of the focal cryoablation device for the treatment of areas of refractory esophageal neoplasia in patients who had undergone first line endoscopic eradication therapy (EET). Complete remission of dysplasia (CR-D) and complete remission of intestinal metaplasia (CR-IM) at first follow-up endoscopy, durability of disease reversal, rates of stenosis and adverse events were studied. Patients and methods Eighteen cases were treated. At baseline, nine patients had low-grade dysplasia (LGD), six had high-grade dysplasia (HGD) and three had intramucosal carcinoma (IMC). Median length of dysplastic Barrett's esophagus (BE) treated was 3 cm. The median number of ablations per patient was 11. Each selected area of visible dysplasia received 10 seconds of ablation. One session of cryoablation was performed per patient. Biopsies were performed at around 3 months post-ablation. Results CR-D was achieved in 78 % and CR-IM in 39 % of patients. There were no device malfunction or adverse events. Stenosis was noted in 11 % of cases. At a median follow up of 19-months, CR-D was maintained in 72 % of patients and CR-IM in 33 %. Conclusions Cryoablation appears to be a viable rescue strategy in patients with refractory neoplasia. It is well tolerated and successful in obtaining CR-D and CR-IM in patients with treatment-refractory BE. Further trials of dosimetry, efficacy and safety in treatment-naïve patients are underway.

Abstract
PURPOSE OF REVIEW Endoscopic screening and surveillance for Barrett's esophagus (BE) as well as treatment of dysplastic BE is well established. A significant proportion of BE patients are older (geriatric age group, > 65 years age). There is relatively little information or recommendations in the literature with regards to evaluation and management of geriatric BE patients. The purpose of this review is to outline specific caveats and best practice recommendations to help manage the geriatric BE patient. RECENT FINDINGS In this review, we have attempted to summarize the latest evidence and guideline-based recommendations for evaluation and treatment of BE and early esophageal neoplasia, with a special focus on the challenges and considerations involved when caring for the geriatric BE patient. Concepts related to sedation, endoscopy, risk-benefit assessment, and other unique issues pertaining to the older BE patient are discussed. Expert recommendations are provided wherever possible. This review highlights the importance of recognizing the unique aspects of evaluating and managing the geriatric BE patient. Practical recommendations are discussed which will help the provider individualize and optimize care for their geriatric BE patient.

Abstract
Endoscopic eradication therapy (EET) has revolutionized management of Barrett's esophagus (BE)-associated neoplasia, traditionally treated by esophagectomy, which carries very high mortality and morbidity. EET, usually performed in the outpatient setting, has a safe risk profile. It is indicated in patients with BE with high-grade dysplasia and intramucosal cancer, confirmed, and persistent low-grade dysplasia, and in highly selected cases of non-dysplastic BE and submucosal cancers. Multiple EET modalities are available and can be categorized into two groups: ablation therapies and resection techniques with resection techniques usually reserved for nodular/raised lesions or lesions with suspected neoplasia. Patients usually require multiple ablation sessions with a goal of achieving complete eradication of metaplasia. Despite very good results, EET has its limitations and is not 100% effective: it targets a small subset of patients along the spectrum of BE and esophageal adenocarcinoma, as most patients with esophageal adenocarcinoma remain asymptomatic until the disease has progressed to advanced stages. Post-ablation surveillance is mandatory, as recurrences are common. An area of concern is buried metaplasia reported to occur following ablation therapy and thought to be from de novo growth of metaplastic tissue underneath the neosquamous epithelium, following ablation. The focus of this review article is to present the indications, contraindications and limitations of EET.

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
Background and study aims Balloon cryoablation (BC) is a novel procedure for endoscopic ablation of Barrett's esophagus (BE- associated neoplasia. We performed a meta-analysis to assess the feasibility, effectiveness, and safety of BC for treatment of BE neoplasia. Patients and methods Several databases were searched for relevant articles (PubMed, Web of Science, Google Scholar, EMBASE) as well as abstracts of recent gastroenterology meetings. Data extraction was performed by two investigators using standardized forms, including age, gender, length of BE segment, prior treatments, procedural time and number ablation sessions, technical feasibility, adverse events, and eradication rates of intestinal metaplasia (CE-IM) and dysplasia (CE-D) at follow-up. Quality of the studies was assessed using a modified Newcastle Ottawa Scale. Results Seven studies met inclusion criteria for a total of 548 ablation sessions in 272 patients. The most common histopathology reported prior to BC was high-grade dysplasia (n = 131), followed by low-grade dysplasia (n = 75), and intramucosal adenocarcinoma (n = 52). The pooled rate for technical feasibility was 95.8 % (95 % CI: 93.6-97.5 %; I 2 = 13.2 %; P = 0.3). Pooled rates of CE-IM and CE-D were 85.8 % (95 % CI: 77.8-92.2 %, I 2 = 55.5 %; p = 0.04) and 93.8 % (95 % CI: 85.5-98.7 %, I 2 = 74.2 %; P = 0.001), respectively. The overall adverse event (AE) rate was 12.5 % (34 out of 272 patients), of which stricture formation was the most common (5.8 %), followed by mucosal laceration (0.7 %), perforation (0.4 %), and bleeding (0.4 %). All AEs were successfully managed endoscopically. Conclusion This meta-analysis suggests that BC is a safe and effective ablative technique for treatment of BE neoplasia; future prospective comparative trials are needed to corroborate these initial findings.

Abstract
DESCRIPTION The purpose of this best practice advice article is to describe the role of Barrett's endoscopic therapy (BET) in patients with Barrett's esophagus (BE) with dysplasia and/or early cancer and appropriate follow-up of these patients. METHODS The best practice advice provided in this document is based on evidence and relevant publications reviewed by the committee. BEST PRACTICE ADVICE 1: In BE patients with confirmed low-grade dysplasia, a repeat examination with high-definition white-light endoscopy should be performed within 3-6 months to rule out the presence of a visible lesion, which should prompt endoscopic resection. BEST PRACTICE ADVICE 2: Both BET and continued surveillance are reasonable options for the management of BE patients with confirmed and persistent low-grade dysplasia. BEST PRACTICE ADVICE 3: BET is the preferred treatment for BE patients with high-grade dysplasia (HGD). BEST PRACTICE ADVICE 4: BET should be preferred over esophagectomy for BE patients with intramucosal esophageal adenocarcinoma (T1a). BEST PRACTICE ADVICE 5: BET is a reasonable alternative to esophagectomy in patients with submucosal esophageal adenocarcinoma (T1b) with low-risk features (<500-μm invasion in the submucosa [sm1], good to moderate differentiation, and no lymphatic invasion) especially in those who are poor surgical candidates. BEST PRACTICE ADVICE 6: In all patients undergoing BET, mucosal ablation should be applied to 1) all visible esophageal columnar mucosa; 2) 5-10 mm proximal to the squamocolumnar junction and 3) 5-10 mm distal to the gastroesophageal junction, as demarcated by the top of the gastric folds (ie, gastric cardia) using focal ablation in a circumferential fashion. BEST PRACTICE ADVICE 7: Mucosal ablation therapy should only be performed in the presence of flat BE without signs of inflammation and in the absence of visible abnormalities. BEST PRACTICE ADVICE 8: BET should be performed by experts in high-volume centers that perform a minimum of 10 new cases annually. BEST PRACTICE ADVICE 9: BET should be continued until there is an absence of columnar epithelium in the tubular esophagus on high-definition white-light endoscopy and preferably optical chromoendoscopy. In case of complete endoscopic eradication, the neosquamous mucosa and the gastric cardia are sampled by 4-quadrant biopsies. BEST PRACTICE ADVICE 10: If random biopsies obtained from the neosquamous epithelium demonstrate intestinal metaplasia/dysplasia or subsquamous intestinal metaplasia, a repeat endoscopy should be performed and visible islands or tongues should undergo targeted focal ablation. BEST PRACTICE ADVICE 11: Intestinal metaplasia of the gastric cardia (without residual columnar epithelium in the tubular esophagus) should not warrant additional ablation therapy. BEST PRACTICE ADVICE 12: When consenting patients for BET, the most common complication of therapy to be quoted is post-procedural stricture formation, occurring in about 6% of cases. Bleeding and perforation occur at rates <1%. BEST PRACTICE ADVICE 13: After complete eradication (endoscopic and histologic) of intestinal metaplasia has been achieved with BET, surveillance endoscopy with biopsies should be performed at the following intervals: for baseline diagnosis of HGD/esophageal adenocarcinoma: at 3, 6, and 12 months and annually thereafter; and baseline diagnosis of low-grade dysplasia: at 1 and 3 years. BEST PRACTICE ADVICE 14: Endoscopic surveillance post therapy should be performed with high-definition white-light endoscopy, including careful inspection of the neosquamous mucosal and retroflexed inspection of the gastric cardia. BEST PRACTICE ADVICE 15: The approach to recurrent disease is similar to that of the initial therapy; visible recurrent nodular lesions require endoscopic resection, whereas flat areas of columnar mucosa in the tubular esophagus can be treated with mucosal ablation. BEST PRACTICE ADVICE 16: Patients should be counseled on cancer risk in the absence of BET, as well as after BET, to allow for informed decision-making between the patient and the physician.

Abstract
Cryotherapy has been used as salvage therapy; however, its efficacy as first line treatment in patients with Barrett's esophagus (BE) neoplasia has not been well studied. The aim of this paper was to perform a systematic review to look at the efficacy of cryotherapy as the primary treatment of BE. An electronic database search was performed (PubMed, Embase, Cochrane, and Google Scholar) to search for studies with cryotherapy as the initial primary modality of ablation in patients with BE neoplasia. Studies that included patients with other prior forms of therapy were excluded. The primary outcomes were the pooled rates of complete eradication of intestinal metaplasia (CE-IM) and CE of neoplasia (CE-N). Secondary outcomes were recurrence rates of neoplasia and intestinal metaplasia (IM) and adverse events. The statistical software OpenMetaAnalyst was used for analysis with pooled estimates reported as proportions (%) with 95% confidence intervals (CI) with heterogeneity (I2) among studies. The search revealed 6 eligible studies with a total of 282 patients (91.5% male, average age 65.3 years) with 459 person years of follow-up. 69.35% [95% CI (52.1%-86.5%)] of patients achieved CE-IM and 97.9% (95% CI: 95.5%-100%) had CE-N. 7.3% of patients had persistent dysplasia with 4% progressing to cancer. The recurrence rate of neoplasia was 10.4 and that of IM was 19.1 per 100 patient years of follow-up. The overall rate of stricture formation was 4.9%. There are scarce data on the use of cryotherapy as the primary modality for the treatment of BE dysplasia. The published data demonstrate efficacy rates of 69% and 98% for complete eradication of metaplasia and neoplasia, respectively. These results need to be assessed in prospective, comparative trials with other forms of therapy.

Abstract
Esophageal cancer is a highly lethal disease and is the sixth leading cause of cancer related mortality in the world. The standard treatment is esophagectomy which is associated with significant morbidity and mortality. This led to development of minimally invasive, organ sparing endoscopic therapies which have comparable outcomes to esophagectomy in early cancer. These include endoscopic mucosal resection and endoscopic submucosal dissection. In early squamous cell cancer, endoscopic submucosal dissection is preferred as it is associated with cause specific 5-year survival rates of 100% for M1 and M2 tumors and 85% for M3 and SM1 tumors and low recurrence rates. In early adenocarcinoma, endoscopic resection of visible abnormalities is followed by ablation of the remaining flat Barrett’s mucosa to prevent recurrences. Radiofrequency ablation is the most widely used ablation modality with others being cryotherapy and argon plasma coagulation. Focal endoscopic mucosal resection followed by radiofrequency ablation leads to eradication of neoplasia in 93.4% of patients and eradication of intestinal metaplasia in 73.1% of patients. Innovative techniques such as submucosal tunneling with endoscopic resection are developed for management of submucosal tumors of the esophagus. This review includes a discussion of various endoscopic techniques and their clinical outcomes in early squamous cell cancer, adenocarcinoma and submucosal tumors. An overview of comparison between esophagectomy and endoscopic therapy are also presented.

Abstract
Barrett esophagus is a metaplastic change in the lining of the distal esophageal epithelium, characterized by replacement of the normal squamous epithelium by specialized intestinal metaplasia. The presence of Barrett esophagus increases the risk of esophageal adenocarcinoma several-fold. Esophageal adenocarcinoma is a malignancy with rapidly rising incidence and persistently poor outcomes when diagnosed after the onset of symptoms. Risk factors for Barrett esophagus include chronic gastroesophageal reflux, central obesity, white race, male gender, older age, smoking, and a family history of Barrett esophagus or esophageal adenocarcinoma. Screening for Barrett esophagus in those with several risk factors followed by endoscopic surveillance to detect dysplasia or adenocarcinoma is currently recommended by society guidelines. Minimally invasive nonendoscopic tools for the early detection of Barrett esophagus are currently being developed. Multimodality endoscopic therapy-using a combination of endoscopic resection and ablation techniques-for the treatment of dysplasia and early adenocarcinoma is successful in eliminating intestinal metaplasia and preventing progression to adenocarcinoma, with outcomes comparable to those after esophagectomy. Risk stratification of those diagnosed with Barrett esophagus is a challenge at present, with active research focused on identifying clinical and biomarker panels to identify those with low and high risk of progression. This narrative review highlights some of the challenges and recent progress in this field.

Liquid Nitrogen Spray Cryotherapy in Treatment of Barrett's Esophagus, where do we stand? A Systematic Review and Meta-Analysis. Dis Esophagus 2019; 32:5304729. [PMID: 30715267 DOI: 10.1093/dote/doy130] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/07/2018] [Revised: 12/06/2018] [Indexed: 12/11/2022]
Abstract
Radiofrequency ablation (RFA) is the preferred treatment option for Barrett's esophagus (BE) to achieve complete eradication (CE) of dysplasia (D), and intestinal metaplasia (IM). Cryotherapy, using liquid nitrogen (LNC), is a cold-induced tissue-injury technique option for the ablation of BE. We conducted a systematic review and meta-analysis to assess the overall efficacy and safety of LNC in the treatment of BE. We conducted a search of multiple electronic databases and conference proceedings from inception through June 2018. The primary outcome was to estimate the pooled rates of CE-IM, CE-D, and CE-HGD. The secondary outcome was to estimate the risk of adverse events and recurrence of disease after LNC. Nine studies reported 386 patients who were treated with LNC. The pooled rate of CE-IM was 56.5% (95% CI 48.5-64.2, I2 = 47), pooled rate of CE-D was 83.5% (95% CI 78.3-87.7, I2 = 22.8), and pooled rate of CE-HGD was 86.5% (95% CI 64.4-95.8, I2 = 88.1). Rate of adverse events was 4.7%, and the risk of BE recurrence was 12.7%. On subgroup analysis, the pooled rate of CE-IM with LNC in patients who failed RFA was 58.4% (95% CI 47.2-68.8, I2 = 32.5), and the pooled rate of CE-D in the same population was 81.9% (95% CI 72.5-88.6, I2 = 5.9). CE-D rates with LNC are comparable to RFA while CE-IM rates appear to be lower than the rates achievable with RFA. CE-IM rate in RFA failed patients is 58.4% and thus LNC is a rescue option to consider in this population.

Abstract
Early detection, including cancer screening and surveillance, is emerging as one of the most important topics in modern oncology. Because symptomatic presentation remains the predominant route to cancer diagnosis, there is a growing interest in developing techniques to detect the disease at an early, curative stage. Moreover, growing understanding of cancer biology has paved the way for prevention studies with the focus on therapeutic interventions for premalignant conditions. Where there is a recognisable precursor stage, such as a colorectal adenoma or Barrett's metaplasia, the removal of abnormal tissue prevents the development of cancer and enables stratification of the patient to a high-risk group requiring further surveillance. Here, we provide a review of the available technologies for early diagnosis and minimally-invasive treatment.

Abstract
PURPOSE OF REVIEW Barrett's esophagus (BE) is the only known measurable factor associated with esophageal adenocarcinoma. The development of endoscopic eradication therapy (EET) has transformed the way BE is managed. Given the fairly recent development of EET, its role in BE is still evolving. RECENT FINDINGS This paper discusses the challenges that endoscopists face at the preprocedural, intraprocedural, and postprocedural stages of BE management. These include challenges in risk stratification, dysplasia detection, ablation methods and dosimetry, choice of resection technique, and management of refractory disease. Despite the advances in EET in BE, there remain challenges that this review focuses on. Future research into these challenges will optimize ablation techniques and strategies in the future.

Chang KJ. Endoscopic foregut surgery and interventions: The future is now. The state-of-the-art and my personal journey. World J Gastroenterol 2019; 25:1-41. [PMID: 30643356 PMCID: PMC6328959 DOI: 10.3748/wjg.v25.i1.1] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/28/2018] [Revised: 12/13/2018] [Accepted: 12/14/2018] [Indexed: 02/06/2023] Open
Abstract
In this paper, I reviewed the emerging field of endoscopic surgery and present data supporting the contention that endoscopy can now be used to treat many foregut diseases that have been traditionally treated surgically. Within each topic, the content will progress as follows: "lessons learned", "technical considerations" and "future opportunities". Lessons learned will provide a brief background and update on the most current literature. Technical considerations will include my personal experience, including tips and tricks that I have learned over the years. Finally, future opportunities will address current unmet needs and potential new areas of development. The foregut is defined as "the upper part of the embryonic alimentary canal from which the pharynx, esophagus, lung, stomach, liver, pancreas, and part of the duodenum develop". Foregut surgery is well established in treating conditions such as gastroesophageal reflux disease (GERD), achalasia, esophageal diverticula, Barrett's esophagus (BE) and esophageal cancer, stomach cancer, gastric-outlet obstruction, and obesity. Over the past decade, remarkable progress in interventional endoscopy has culminated in the conceptualization and practice of endoscopic foregut surgery for various clinical conditions summarized in this paper. Regarding GERD, there are now several technologies available to effectively treat it and potentially eliminate symptoms, and the need for long-term treatment with proton pump inhibitors. For the first time, fundoplication can be performed without the need for open or laparoscopic surgery. Long-term data going out 5-10 years are now emerging showing extended durability. In respect to achalasia, per-oral endoscopic myotomy (POEM) which was developed in Japan, has become an alternative to the traditional Heller's myotomy. Recent meta-analysis show that POEM may have better results than Heller, but the issue of post-POEM GERD still needs to be addressed. There is now a resurgence of endoscopic treatment of Zenker's diverticula with improved technique (Z-POEM) and equipment; thus, patients are choosing flexible endoscopic treatment as opposed to open or rigid endoscopy options. In regard to BE, endoscopic submucosal dissection (ESD) which is well established in Asia, is now becoming more mainstream in the West for the treatment of BE with high grade dysplasia, as well as early esophageal cancer. In combination with all the ablation technologies (radiofrequency ablation, cryotherapy, hybrid argon plasma coagulation), the entire spectrum of Barrett's and related dysplasia and early cancer can be managed predominantly by endoscopy. Importantly, in regard to early gastric cancer and submucosal tumors (SMTs) of the stomach, ESD and full thickness resection (FTR) can excise these lesions en-bloc and endoscopic suturing is now used to close large defects and perforations. For treatment of patients with malignant gastric outlet obstruction (GOO), endoscopic gastro-jejunostomy is now showing better results than enteral stenting. G-POEM is also emerging as a treatment option for patients with gastroparesis. Obesity has become an epidemic in many western countries and is becoming also prevalent in Asia. Endoscopic sleeve gastroplasty (ESG) is now becoming an established treatment option, especially for obese patients with body mass index between 30 and 35. Data show an average weight loss of 16 kg after ESG with long-term data confirming sustainability. Finally, in respect to endo-hepatology, there are many new endoscopic interventions that have been developed for patients with liver disease. Endoscopic ultrasound (EUS)-guided liver biopsy and EUS-guided portal pressure measurement are exciting new frontiers for the endo-hepatologists.

Abstract
Background and study aims This is a case report on use of the CryoBalloon as a salvage technique for ablation of residual neoplasia at an endoscopic mucosal resection site. The site contained an embedded clip that could not be removed at two different sessions by three experienced endoscopists. On follow-up endoscopy, the clips and residual polyp no longer remained. The subtle scar that was present was biopsied and confirmed complete eradication of neoplasia and no polyp tissue. This case shows the potential of the CryoBalloon to ablate unwanted tissue outside of the esophagus.

Abstract
Endoscopic cryotherapy is a relatively new thermal ablative modality used for the treatment of neoplastic lesions of the esophagus. It relies on cycles of rapid cooling and thawing to induce tissue destruction with a cryogen (liquid nitrogen or carbon dioxide) leading to intra and extra-cellular damage. Surgical treatment was once considered the standard therapeutic intervention for neoplastic diseases of the esophagus and is associated with considerable rates of morbidity and mortality. Several trials that evaluated cryotherapy in Barrett’s esophagus (BE) associated neoplasia showed reasonable efficacy rates and safety profile. Cryotherapy has also found applications in the treatment of esophageal cancer, both for curative and palliative intent. Cryotherapy has also shown promising results as salvage therapy in cases refractory to radiofrequency ablation treatment. Cryoballoon focal ablation using liquid nitrogen is a novel mode of cryogen delivery which has been used for the treatment of BE with dysplasia and squamous cell carcinoma. Most common side effects of cryotherapy reported in the literature include mild chest discomfort, esophageal strictures and bleeding. In conclusion, cryotherapy is an effective and safe method for the treatment of esophageal neoplastic processes, ranging from early stages of low grade dysplasia to esophageal cancer.

Abstract
Modern recognition and management of Barrett's esophagus, a precursor to esophageal adenocarcinoma depends on diagnostic accuracy, risk assessment, technical expertise and consideration of many options to best tailor therapy for every patient. Concomitant management of acid reflux is essential, frequently with proton pump inhibitors. Ablation and resection favorably affect the evolution towards cancer. Using precision medicine tools, such as imaging, molecular diagnostics and analytics may lead to cost- and comparatively-effective therapies ultimately aiming at cancer prevention. Knowledge of the risk factors for Barrett's esophagus and progression to dysplasia and cancer can help tailor a precision medicine approach with more aggressive screening and surveillance targeted at patients that are most likely to benefit.

Abstract
Since Barrett’s esophagus is a precancerous condition, efforts have been made for its eradication by various ablative techniques. Initially, laser ablation was attempted in non-dysplastic Barrett’s esophagus and subsequently, endoscopic ablation using photodynamic therapy was used in Barrett’s patients with high-grade dysplasia who were poor surgical candidates. Since then, various ablative therapies have been developed with radiofrequency ablation having the best quality of evidence. Resection of dysplastic areas only without complete removal of entire Barrett’s segment is associated with high risk of developing metachronous neoplasia. Hence, the current standard of management for Barrett’s esophagus includes endoscopic mucosal resection of visible abnormalities followed by ablation to eradicate remaining Barrett’s epithelium. Although endoscopic therapy cannot address regional lymph node metastases, such nodal involvement is present in only 1% to 2% of patients with intramucosal adenocarcinoma in Barrett esophagus and therefore is useful in intramucosal cancers. Post ablation surveillance is recommended as recurrence of intestinal metaplasia and dysplasia have been reported. This review includes a discussion of the technique, efficacy and complication rate of currently available ablation techniques such as radiofrequency ablation, cryotherapy, argon plasma coagulation and photodynamic therapy as well as endoscopic mucosal resection. A brief discussion of the emerging technique, endoscopic submucosal dissection is also included.
