Barret esophagous

Maximilien Barret, Frédéric Prat
Endoscopy allows for the screening, early diagnosis, treatment and follow up of superficial esophageal cancer. Endoscopic submucosal dissection has become the gold standard for the resection of superficial squamous cell neoplasia. Combinations of endoscopic mucosal resection and radiofrequency ablation are the mainstay of the management of Barrett's associated neoplasia. However, protruded, non-lifting or large lesions may be better managed by endoscopic submucosal dissection. Novel ablation tools, such as argon plasma coagulation with submucosal lifting and cryoablation balloons, are being developed for the treatment of residual Barrett's esophagus, since iatrogenic strictures still hamper the development of extensive circumferential resections in the esophagus...

The pathophysiology of achalasia is largely unknown, and involves the destruction of ganglion cell in the esophageal myenteric plexus. High-resolution esophageal manometry is the key investigation. Endoscopic pneumodilatation and laparoscopic Heller myotomy have comparable short-term success rates, around 90%. The main complication after pneumodilatation is esophageal perforation, occurring in about 1% of cases. Peroral endoscopic myotomy is a promising treatment modality, however with frequent post-procedural gastroesophageal reflux...

Achalasia of the cardia is associated with an increased risk of esophageal carcinoma. The real burden of achalasia at the malignancy genesis is still a controversial issue. Therefore, there are no generally accepted recommendations on follow-up evaluation for achalasia patients. This study aims to estimate the risk of esophageal adenocarcinoma and squamous cell carcinoma in achalasia patients. We searched for association between carcinoma and esophageal achalasia in databases up to January 2017 to perform a systematic review and meta-analysis...

Esophageal stricture formation after extensive endoscopic resection remains a major limitation of endoscopic therapy for early esophageal neoplasia. This study assessed a recently developed self-assembling peptide (SAP) matrix as a wound dressing after endoscopic resection for the prevention of esophageal stricture. Ten pigs were randomly assigned to the SAP or the control group after undergoing a 5-cm-long circumferential endoscopic submucosal dissection of the lower esophagus. Esophageal diameter on endoscopy and esophagogram, weight variation, and histological measurements of fibrosis, granulation tissue, and neoepithelium were assessed in each animal...

Esophageal adenocarcinoma (EAC) represents the sixth leading cause of cancer-related deaths and develops in Barret's esophagus affected tissues. The IGF2 mRNA binding protein IMP2/IGF2BP2/p62 was originally identified as an autoantigen in hepatocellular carcinoma. Aim of this study was to investigate the expression and prognostic role of IMP2 in EAC. Human EAC and Barret's esophagus tissue showed overexpression of IMP2, particularly in tumors of increased size and in metastatic tissues. Molecular classification based on published gene signatures of esophageal cancer revealed a specific subtype, in which the expression of IMP2 is high...

BACKGROUND: In the past, ambulatory 24-h manometry has been shown useful for the evaluation of patients with non-cardiac chest pain (NCCP). With the diagnostic improvements brought by pH-impedance monitoring and high-resolution manometry (HRM), the contribution of ambulatory 24-h manometry to the diagnosis of esophageal hypertensive disorders has become uncertain. Our aim was to assess the additional diagnostic yield of ambulatory manometry to HRM and ambulatory pH-impedance monitoring in this patient population...

The most important novel findings presented on oesophageal disease in DDW 2015 were the following: 1) GERD: a) hypervigilance seems to be a key pathogenic factor in reflux symptoms refractory to PPI; b) post-reflux swallowing-induced peristaltic waves could be an excellent diagnostic criterion for GERD; c) laryngeal pH-metry is not useful in the diagnosis of extra-oesophageal symptoms; d) the recommendation of weight loss adequately recorded in the clinical reports of patients with GERD and obesity or overweight is an excellent quality indicator and is associated with better outcomes...

The development of techniques for endoscopic resection has provided new strategies for radical conservative treatment of superficial esophageal neoplasms, even those that are circumferential, such as Barrett's neoplasia. However, it is necessary to prevent the formation of scar tissue that can be responsible for esophageal strictures following circumferential resection. Preliminary data have suggested the possible efficacy of a hemostatic powder in the promotion of wound healing. The study aims to assess the effectiveness of Hemospray (Cook Medical) in a swine model of post-endoscopic esophageal stricture...

BACKGROUND AND AIMS: The prevention of esophageal strictures following circumferential mucosal resection remains a major clinical challenge. Human amniotic membrane (AM) is an easily available material, which is widely used in ophthalmology due to its wound healing, anti-inflammatory and anti-fibrotic properties. We studied the effect of AM grafts in the prevention of esophageal stricture after endoscopic submucosal dissection (ESD) in a swine model. ANIMALS AND METHODS: In this prospective, randomized controlled trial, 20 swine underwent a 5 cm-long circumferential ESD of the lower esophagus...

BACKGROUND: Endoscopic esophageal piecemeal mucosectomy for high-grade dysplasia on Barrett's esophagus leads to suboptimal histologic evaluation, as well as recurrence on remaining mucosa. Circumferential en bloc mucosal resection would significantly improve the management of dysplastic Barrett's esophagus. Our aim was to describe a new method of esophageal circumferential endoscopic en bloc submucosal dissection (CESD) in a swine model. METHODS: After submucosal injection, circumferential incision was performed at each end of the esophageal segment to be removed...

Barrett's esophagus consists of the replacement of normal squamous epithelium by a specialised columnar lined epithelium referred to as intestinal metaplasia in the esophagus. It represents a premalignant lesion. The prevalence of Barrett's esophagus is around 1.6%. Esophageal adenocarcinoma results from the development of dysplasia progressing from low to high grade dysplasia and finally adenocarcinoma. Radiofrequency ablation currently represents the treatment of choice in eradicating Barrett's esophagus with associated dysplasia...

The nematode Spirocerca lupi (S. lupi) induces sarcoma in the dog oesophagus in about 25% of cases. The aim of this study was to compare the differences in the cytokine milieu between dogs with neoplastic (n=29) and non-neoplastic disease (n=49) and age- and gender-matched healthy controls (n=25). We measured IL-2, IL-4, IL-6, IL-8, IL-10, IL-18, GM-CSF and MCP-1 in a specific canine multiplex immunoassay kit. Cytokine concentrations were compared between the different groups using the Kruskal-Wallis test followed by Dunn's test...

BACKGROUND: Circumferential endoscopic submucosal dissection (CESD) of the esophagus would allow for both the eradication of Barrett's esophagus and its related complications, such as advanced neoplasia. However, such procedures generally induce inflammatory repair resulting in a fibrotic stricture. N-acetylcysteine (NAC) is an antioxidant that has shown some efficacy against pulmonary and hepatic fibrosis. The aim of our study was to evaluate the benefit of NAC in the prevention of esophageal cicatricial stricture after CESD in a swine model...

BACKGROUND: Esophageal adenocarcinoma (EAC) is a rarely curable disease and is rapidly rising worldwide in incidence. Barret's esophagus (BE) and high-grade dysplasia (HGD) are considered major risk factors for invasive adenocarcinoma. In the current study, unbiased global metabolic profiling methods were applied to serum samples from patients with EAC, BE and HGD, and healthy individuals, in order to identify metabolite based biomarkers associated with the early stages of EAC with the goal of improving prognostication...

Barret's esophagus (BE) is defined as a situation in which the distal esophageal squamous epithelium was replaced by columnar epithelium, with or without goblet cells. BE is considered a significant risk factor for the development of esophageal cancer, however, screening is recommended only for high risk patients. The new guidelines determine the proper terminology of the endoscopic appearance of BE and the way that biopsies should be taken. After BE is confirmed, surveillance is extremely important as its performance has been shown to prevent cancer and death...

Endoscopic therapies for the treatment of complicated Barret's esophagus should be embraced by the surgical community. While esophagectomy remains the standard of care for early esophageal neoplasia in many centers, endoscopic techniques are being increasingly utilizid. As refinements in both endoscopic and surgical approaches continue to evolve, accurate and contempary assessments of outcomes are critical in assuring that each is applied in appropriate circumstances.

Increasing incidence of adenocarcinoma of the esophagus is nowadays observed in western countries. Estimation of the unique molecules may, in the future, lead to early diagnostics of pathological changes in the Barret esophagus and identification of the patient at risk from cancerogenesis. The aim of this study is to explain terminology of Barret esophagus, basis of histopatology, diagnostics and to show molecules which have crucial significance in cancerogenesis.
