BACKGROUND: Establishing postnatal nutrition delivery is challenging in neonates with immature sucking and swallowing ability. Enteral feeding is the gold standard for such patients, but their small size and fragility present challenges in nasogastric (NG) feeding tube placement. Feeding tubes are typically placed with x-ray guidance, which provides minimal soft tissue contrast and exposes the baby to ionizing radiation. This research investigates magnetic resonance (MR) guidance of NG feeding tube placement in neonates to provide improved soft tissue visualization without ionizing radiation...

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: Endoscopic resections have low morbidity and mortality. Delayed bleeding has been reported in approximately 1 - 15 % of cases, increasing with antiplatelet/anticoagulant therapy or portal hypertension. A self-assembling peptide (SAP) forming a gel could protect the mucosal defect during early healing. This retrospective trial aimed to assess the safety and efficacy of SAP in preventing delayed bleeding after endoscopic resections. METHODS: Consecutive patients with endoscopic resections were enrolled in two tertiary referral centers...

INTRODUCTION: The possible benefit of endoscopic submucosal dissection (ESD) for early neoplasia arising in Barrett's esophagus remains controversial. We aimed to assess the efficacy and safety of ESD for the treatment of early Barrett's neoplasia. METHODS: All consecutive patients undergoing ESD for the resection of a visible lesion in a Barrett's esophagus, either suspicious of submucosal infiltration or exceeding 10 mm in size, between February 2012 and January 2015 were prospectively included...

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...

Gastroesophageal reflux disease (GERD) is a disorder, which gastric content repeatedly reflux into the esophagus causing disturbing symptoms and/or complications. Various epidemiological studies show that there is regional difference on the aspect of prevalence and clinical manifestation. Regional data also demonstrates increased incidence of complications such as the Barret's Esophagus and adenocarcinoma. In response to the situation, the Asia-Pacific GERD experts, including Indonesia, had published a consensus on the management of GERD in 2004, which was subsequently revised in 2008...

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...

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...

We study the invasion dynamics of a mutant population characterized by an increased phenotypic variability with respect to the incumbent population, with an emphasis on the effects of increased phenotypic robustness and fluctuations induced by small system size. This model is based on recent experimental and theoretical results which hint at the possibility that inactivation of certain genes, either by the effect of mutations or by pharmacological intervention, leads to the liberation of cryptic genetic variation which, in turn, produces a host of new phenotypic variants...

REVIEW
T J Watson, J H Peters
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.
