Background: Endotherapy in cases of neoplastic Barrett esophagus (BE) relapse after successful initial endoscopic management is commonly accepted, but few studies analyze this topic and also take into account the metachronous lesions., Aims: To evaluate the efficiency of endotherapy in the case of neoplastic BE relapse after successful complete endoscopic eradication of neoplastic BE and metaplastic BE., Methods: Retrospective review of medical records was collected in a computerized and prospective manner between 2000 and 2015, in a single tertiary care center. Recurrence was defined by histological presence of high-grade dysplasia or superficial adenocarcinoma at least 6 months after the end of successful initial endotherapy., Results: Eighteen patients were assessed (1F/17 M). Delay between initial treatment and relapse was 16.6 months (range 6-33). Endotherapy for relapse obtained a sustained and complete remission for 8/18 (44%) patients, with an average endoscopic follow-up of 28 months. The complication rate of endotherapy was 6%. Surgical management was required in 33% (2 pT2N0M0, 2 pTisN0M0, 1 pTm2N0M0 and 1 pTm3N0M0) and salvage radiochemotherapy in 17% (3/18). One patient treated by 6 sessions of ER was considered as a failure given the multiple sessions of endotherapy. Multivariate analysis showed that length of BE (>5 cm), late stenosis adverse events and the quality of vertical margin during initial ER are predictive factors for disease-free survival (p value < 0.01, Hazard Ratio up to 0.076)., Conclusion: Endotherapy could be a treatment for management of neoplastic BE relapse, but should be carefully used, with strict follow-up.

Background and Aims: Endotherapy (ET) has replaced surgery as the first-line treatment of high-grade dysplasia (HGD)/superficial ECA (ECAs) from Barrett's oesophagus (BO). However, long-term follow-up and predictive factors of relapse are not so well studied. The aim of the following study was to evaluate the efficiency of ET for treatment of HGD/ECAs and to determine factors of long-term efficiency., Methods: ET procedures were manually reported and registered in a hospital data base from March 2000 to July 2010. Inclusion criteria were HGD/ECA on pre-resection biopsies, complete histological and sufficient oncological resection of HGD/ECAs, and complete macroscopic resection of metaplastic BO. Sixty patients (53 men, mean age = 65 years) were included., Results: Median follow-up was 66 months [range 42-80]. Complete eradication of residual histological metaplastic BO occurred in 29 patients (48 %). Relapse rate at 36 months was 16.6 % (n = 10) and was unchanged at 60 months of follow-up. There was only one relapse (3.4 %) in case of complete eradication of metaplastic BO and 9 (31 %) in case of incomplete eradication. In univaried and multi-varied analysis, complete eradication of metaplastic BO (p < 0.05) and BO length <5 cm (p < 0.05) were predictive of neoplastic BO non relapse. The length of BO remained a prognostic factor for disease-free survival (DFS). When these preponderant data were cancelled out in multi-varied analysis, complete eradication of BO was a prognostic factor for DFS (p < 0.05)., Conclusion: Complete histological eradication of BO by ET significantly decreases the rate of neoplasia relapse.

Unlabelled: Endoscopic resection (EMR) and radiofrequency ablation (RFA) form part of the treatment of Barrett's oesophagus (BO), dysplasia, superficial adenocarcinoma (OAC) associated with BO., Patients and Methods: Between June 2008 and April 2011, 34 patients underwent treatment with RFA (HALO system(®)), in a tertiary centre. For the study, patients were divided into two groups. Group 1 (16 patients of average 60 years old; 14 men, two women) received EMR and RFA. Group 2 (18 patients averaging 59 years age; 14 men, four women) received RFA without EMR in the year preceding the RFA., Results: In group 1, high grade dysplasia (HGD) was eradicated in 12 cases (92%), low grade dysplasia (LGD) in three cases (100%). Complete response occurred in nine cases (56%), partial response in 100% of cases. Mean follow-up was 15 months. In group 2, HGD was eradicated in one patient (100%), LGD in three patients (64%). A complete response was achieved in eight patients, partial response in four cases (77%). Mean follow-up was 10 months. The complication rate for groups 1 and 2 was of 18% and 10% respectively. No complication prevented completion of treatment or continued monitoring. Recurrence was evaluated to 5% in both groups., Conclusion: RFA associated with EMR is feasible, offering probably better results and a very important advantage: a more complete histology before follow-up. Our results show effective treatment of BO and associated dysplasia with a low rate of complication. Nevertheless, when new techniques of BO ablation are used, the need to obtain histology before treatment should not be forgotten., (Copyright © 2012 Elsevier Masson SAS. All rights reserved.)

Background: Barrett's esophagus-related high-grade dysplasia or mucosal cancer can be treated by endoscopic mucosal resection (EMR), but the adjacent metaplastic epithelium remains at risk for developing further lesions. Our objective was to evaluate the results of the circumferential EMR in removing not only the neoplastic lesion but also the remaining Barrett's epithelium., Methods: Forty-one consecutive patients (mean age: 66 years) with Barrett's esophagus were submitted to 63 EMR sessions in one single-referral endoscopic unit. All patients had high-grade dysplasia, and cancer was detected in 23 of these cases, most of them classified as T1N0 (20 patients) by endosonography. Mucosectomy after saline submucosal injection was performed for the neoplastic lesions and, if necessary, the residual Barrett's epithelium was removed by the same technique one month later., Results: A retrospective evaluation showed that, during a mean follow-up of 31.6 months, Barrett's epithelium was completely replaced by squamous epithelium in 31 (75.6%) cases. There were 10 complications, all of which were managed endoscopically: 8 cases of bleeding and two perforations occurred in 9 (14.3%) patients. One patient developed an esophageal stricture. Barrett's epithelium recurred in 10 (24.4%) patients and recurrent or metachronous early cancer was detected in 5 (12.2%), all but one of which were treated again by EMR; the fifth patient was referred to surgery. Argon plasma coagulation was used in 6 cases to treat Barrett's epithelium, and two patients received concomitant chemoradiotherapy as adjuvant therapy., Conclusions: Circumferential EMR provides an effective endoscopic approach to the management of Barrett's esophagus-related high-grade dysplasia and mucosal cancer. Additional studies are necessary to evaluate the long-term results.
