Impedance and Histologic Characteristics of the Sub-laryngeal Esophagus Distinguish Eosinophilic Esophagitis From Other Esophageal Disorders.

The region of the esophagus 15-17 cm below the incisors, called the sub-upper esophageal sphincter (sub-UES), has not been characterized in adults with eosinophilic esophagitis (EoE) but appears different during endoscopy. We investigated how the sub-UES differs from the remaining esophagus in patients with EoE and aimed to determine whether these differences be used to distinguish patients with EoE from those with lichen planus.


Vascular pressure bands on high-resolution esophageal manometry with impedance studies.

Horizontal pressure bands on high-resolution esophageal manometry with impedance (HREMI) tracings are often seen and thought to be due to cardiovascular structures compressing the esophagus. The aim of this study was to determine the prevalence and location of vascular pressure bands on HREMI studies and correlate these pressure bands to bolus clearance. HREMI studies in supine and upright positions from patients and normal volunteers were reviewed. Pressure bands were defined as bands of horizontal pressur...

Imaging for Barrett's esophagus: state of the art.

Barrett's esophagus is the premalignant condition for esophageal cancer and the diagnosis of esophageal adenocarcinoma on index endoscopy is increasing. Many advanced endoscopic techniques are available and aim to identify Barrett's esophagus-associated neoplasia earlier, thereby preventing progression into malignancy.


Clinical Practice Update: Endoscopic treatment of Barrett's esophagus with dysplasia and/or early cancer.

The purpose of this best practice advice article is to describe, in patients with Barrett's esophagus (BE) with dysplasia/early cancer, the role of Barrett's endoscopic therapy (BET) and appropriate follow-up of these patients.

Laparoscopic Collis-Nissen approach for shortened esophagus treatment in children.

Short esophagus is a disability to obtain a proper portion of abdominal esophagus, thus a lengthening technique is required. Collis approach is the best option.

Detection of the prostate cancer biomarker PCA3 with electrochemical and impedance-based biosensors.

Diagnosis of prostate cancer via PCA3 biomarker detection is promising to be much more efficient than with the prostatic specific antigens currently used. In this study, we present the first electrochemical and impedance-based biosensors that are capable of detecting PCA3 down to 0.128 nmol/L. The biosensors were made with a layer of PCA3-complementary single-stranded DNA (ssDNA) probe, immobilized on a layer-by-layer (LbL) film of chitosan (CHT) and carbon nanotubes (MWCNT). They are highly selective to PC...

Multiple primary cancers in patients treated for squamous cell carcinoma of the esophagus.

Treatment of squamous cell carcinoma is associated with an increased risk of other primary malignancies, mainly within the head and neck, as well as in the oesophageal gastric graft. More frequent recognition of multiple primary cancers associated with esophageal cancer, both synchronous and metachronous, is associated with longer follow-up after radical cancer treatment for esophageal cancer and high quality diagnostic procedures, both before and after surgery. The paper reviews the available literature an...

Failure of standard methods for retrieving an unusual foreign body in esophagus: A case report.

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.

Distal esophagus is the most commonly involved site for strictures in patients with eosinophilic esophagitis.

While strictures are common in eosinophilic esophagitis (EoE), there are few data on stricture distribution and characteristics. Our primary aim was to characterize strictures by location in the esophagus in EoE and associated clinical, endoscopic, and histologic features. This was a retrospective study from the UNC EoE Clinicopathologic Database of subjects with esophageal strictures or narrowing from 2002 to 2017. Strictures were categorized as distal esophagus/gastroesophageal junction, mid-esophagus, pr...

Squamous Cell Carcinoma in Lichen Planus of the Esophagus.

Cancer arising in lichen planus of the esophagus (LPE) is extremely rare. We report 2 elderly female patients with LPE who developed squamous cell carcinoma (SCC). Both underwent laparoscopic ischemic gastric preconditioning followed 2 weeks later by 3-field esophagectomy. Final pathological stages were carcinoma-in-situ and pT3N2, respectively. No adjuvant therapy was given. The patient with in-situ cancer has no evidence of recurrence at 24 months. The 2 patient opted to follow up locally and died 8 month...

Ankle Mechanical Impedance During the Stance Phase of Running.

Differences in locomotor biomechanics between walking and running provide fundamental information about human ambulation. Joint mechanical impedance is a biomechanical property that governs the body's instantaneous response to disturbances, and is important for stability and energy transfer. Ankle impedance has been characterized during walking, but little is known about how humans alter joint impedance during running. The purpose of this study was to estimate ankle impedance during the stance phase of runn...

Liquid nitrogen spray cryotherapy-based multimodal endoscopic management of dysplastic Barrett's esophagus and early esophageal neoplasia: retrospective review and long-term follow-up at an academic tertiary care referral center.

Endoscopic eradication therapy of dysplastic Barrett's esophagus (BE) and early esophageal neoplasia has emerged as an effective treatment option. Data for the role of spray cryotherapy (SCT) in this setting is relatively limited.

In vivo imaging of deep neural activity from the cortical surface during hippocampal epileptiform events in the rat brain using electrical impedance tomography.

Electrical impedance tomography (EIT) is a medical imaging technique which reconstructs images of the internal impedance changes within an object using non-penetrating surface electrodes. To date, EIT has been used to image fast neural impedance changes during somatosensory evoked potentials and epileptiform discharges through the rat cerebral cortex with a resolution of 2 m s and

A Comparison of Patient-Reported Health-Related Quality of Life During Proton Versus Photon Chemoradiotherapy for Esophageal Cancer.

The purpose of this study was to compare Functional Assessment of Cancer Therapy - Esophagus (FACT-E) questionnaire changes during proton (PRT) or photon (XRT) chemoradiotherapy (CRT) for esophageal cancer (EC).

No Barrett-No Cancer: A Proposed New Paradigm for Prevention of Esophageal Adenocarcinoma.

Esophageal adenocarcinoma is inflammation-associated cancer with a recognizable preneoplastic stage, Barrett esophagus. Barrett esophagus describes the metaplastic transformation of esophageal squamous mucosa into columnar epithelium that typically results secondary to mucosal damage caused by acidic gastroduodenal reflux. Continued acid reflux may then result in mucosal inflammation which results in progressive inflammation-induced genetic instability that may eventuate in esophageal adenocarcinoma. Barret...

CATCHING UP TO THE COLON: TIME FOR AN ADENOMA DETECTION RATE EQUIVALENT IN BARRETT'S ESOPHAGUS?

Barrett's esophagus (BE) is the only known precursor to esophageal adenocarcinoma (EAC), a cancer associated with a dismal 5-year survival rate (Am J Gastroenterol 2017;112(7):1032-1048). Despite all the advances in this field, we have had minimal impact on the incidence, morbidity and mortality related to this lethal cancer. This has provided the impetus for major gastroenterology societies to propose quality indicators to guide diagnostic, surveillance and treatment strategies including endoscopic eradica...

IS THERE A RELATION BETWEEN HELYBACTER PYLORI AND INTESTINAL METAPLASIA IN SHORT COLUMN EPITELIZATION UP TO 10 MM IN THE DISTAL ESOPHAGUS?

The presence of intestinal metaplasia in the distal esophagus (Barrett's esophagus) is an important precursor of adenocarcinoma. Knowledge of the risk factors and the process by which the Barrett develops is very important and Helicobacter pylori (HP) can contribute to this development.

Precision Surgical Therapy for Adenocarcinoma of the Esophagus and Esophagogastric Junction.

To facilitate initial clinical decision whether to use esophagectomy alone or neoadjuvant therapy in surgical care for individual patients with adenocarcinoma of the esophagus and esophagogastric junction-information not available from randomized trials-a machine-learning analysis was performed using worldwide real-world data on patients undergoing different therapies for this rare adenocarcinoma.

The outcome of fundoplication in patients with GERD based on abnormal impedance testing.

The role of impedance testing in selecting patients for antireflux surgery is poorly understood. The aim of this study was to compare the outcomes of patients that underwent antireflux surgery for GERD based on an abnormal pH/abnormal impedance test versus a normal pH/abnormal impedance test.
