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.
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...
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.
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.
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.
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...
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...
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.
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...
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...
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.
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
To determine the factors associated with the spontaneous passage (SP) of coins lodged in the esophagus in children.
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).
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...
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...
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.
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 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.
A case report of successful surgical treatment of spontaneous rupture of the esophagus in a patient with chronic obstructive pulmonary disease, bronchial asthma and obesity is presented. Rupture of the esophagus occurred during a coughing without vomiting.
The Fricke-Morse impedance model is widely used in bioelectrical impedance analysis (BIA), which is usually fitted by multi-frequency electrical impedance data. Here, we propose a novel numerical method for estimating the model parameters using single-frequency sinusoidal excitation.
With the increasing need for multi-analyte point-of-care diagnosis devices, cell impedance measurement is a promising technique for integration with other sensing modalities. In this comprehensive review, the theory underlying cell impedance sensing, including the history, complementary metal-oxide-semiconductor (CMOS) based implementations, and applications are critically assessed. Whole cell impedance sensing, also known as electric cell-substrate impedance sensing (ECIS) or electrical impedance spectrosc...
