BACKGROUND: The use of esophageal catheters with microtransducer promises advantages over traditional catheters with air-filled balloons. However, performance comparisons between these 2 types of catheters are scarce and incomplete. METHODS: A catheter with a 9.5-cm air-filled balloon at the distal tip and a catheter with a microtransducer mounted within a flexible silicone rubber were tested in vitro and in vivo. In vitro, the response times of both catheters were compared, and the drift of the baseline pressure of the microtransducer catheter was evaluated over a 6-h period...

The authors present a case of a 38-year-old man with a 4-hour history of accidental removal of a jejunostomy balloon-tube replacement (PEG-18-BRT-S, Cook Medical Inc., Bloomington, USA). The patient had undergone a direct percutaneous endoscopic jejunostomy (DPEJ) ten months ago, before chemoradiotherapy treatment for an esophageal squamous-cell carcinoma (uT3N2cM0). His past medical condition included alcoholic liver disease and distal gastrectomy from a life-threatening duodenal bleeding ulcer.

Esophageal balloons are used in the respiratory monitoring of critical care patients. After the esophageal pressure is measured, the corresponding pleural pressure in the thorax can be projected, enabling lung-thorax compliance to be partitioned into chest-wall compliance and lung compliance. The esophageal balloon allows determination of transpulmonary pressures and a correspondingly individually tailored approach to respiratory care, such as patient-specific titration of positive end-expiratory pressure for patients with extrapulmonary acute respiratory distress syndrome...

This study tested the primary hypothesis that there is a correlation of maximum pain threshold (MPT) in the esophagus and rectum in persons with functional heartburn. Secondary aims evaluated correlations with initial perception threshold (IPT) and pain threshold (PT). This study explored objective sensory endpoints of IPT, PT, and MPT in the esophagus and rectum of 14 females with functional heartburn to determine whether visceral hypersensitivity is generalized or organ-specific. Data on volume and pressure measurements at IPT, PT, and MPT with esophageal and rectal barostat distention were collected...

BACKGROUND AND STUDY AIM: The incidence of stricture formation caused by endoscopic submucosal dissection (ESD) for widespread lesions is high, and stricture formation can reduce quality of life. We evaluated the prophylactic efficacy of hybrid therapy using a locoregional steroid injection and polyglycolic acid (PGA) sheets with fibrin glue to prevent stricture formation after esophageal ESD in high risk patients in whom we predicted stricture formation would be difficult to prevent with a single prophylactic steroid injection...

PURPOSE: In this study, we present the clinical implementation of a novel transoral balloon centering esophageal applicator (BCEA) and the initial clinical experience in high-dose-rate (HDR) brachytherapy treatment of esophageal cancer, using this applicator. MATERIAL AND METHODS: Acceptance testing and commissioning of the BCEA were performed prior to clinical use. Full performance testing was conducted including measurements of the dimensions and the catheter diameter, evaluation of the inflatable balloon consistency, visibility of the radio-opaque markers, congruence of the markers, absolute and relative accuracy of the HDR source in the applicator using the radiochromic film and source position simulator, visibility and digitization of the applicator on the computed tomography (CT) images under the clinical conditions, and reproducibility of the offset...

PURPOSE: Pleural pressure measured with esophageal balloon catheters (Peso) can guide ventilator management and help with the interpretation of hemodynamic measurements, but these catheters are not readily available or easy to use. We tested the utility of an inexpensive, fluid-filled esophageal catheter (Peso) by comparing respiratory-induced changes in pulmonary artery occlusion (Ppao), central venous (CVP), and Peso pressures. METHODS: We studied 30 patients undergoing elective cardiac surgery who had pulmonary artery and esophageal catheters in place...

Most ingested foreign bodies are best treated with endoscopically. If the sharp-pointed objects embedded in the esophageal wall, it may not be able to be removed by conventional endoscopic devices and surgery is required. Herein, we described a new technique for the extraction of both ends embedded sharp-pointed objects in the esophageal wall.

Stimulation of the esophagus activates the pharyngeal swallow response (EPSR) in human infants and animals. The aims of this study were to characterize the stimulus and response of the EPSR, and to determine the function and mechanisms generating the EPSR. Studies were conducted in 46 decerebrate cats in which pharyngeal, laryngeal and esophageal motility was monitored using EMG, strain gauges, or manometry. The esophagus was stimulated by balloon distension or luminal fluid infusion. We found that esophageal distension increased the chance of occurrence of the EPSR, but the delay was variable...

Achalasia is a rare esophageal motility disorder that is usually idiopathic in origin. It is characterized by dysphagia, and patients often have chest pain, regurgitation, weight loss, and an abnormal barium radiograph showing esophageal dilation with narrowing at the gastroesophageal junction. Abnormal or absent esophageal peristalsis and impaired relaxation of the lower esophageal sphincter (LES) are typically seen on esophageal manometry. The advent of high resolution manometry (HRM) has allowed more precise diagnosis of achalasia, subtype designation, and differentiation from other esophageal motor disorders with an initial seminal publication in 2008 followed by further refinements of what has been termed the Chicago classification...

BACKGROUND: The optimal target of endoscopic dilation of postsurgical esophageal strictures is unknown. Our aim was to compare the dilation-free period of patients who underwent dilation up to 16 mm with patients who were dilated up to 17 or 18 mm. METHODS: We retrospectively analyzed adult patients who received bougie/balloon dilation for a benign anastomotic stricture after esophagectomy. An anastomotic stricture was defined as dysphagia in combination with a luminal diameter of ≤13 mm at endoscopy...

BACKGROUND: High-frequency oscillatory ventilation (HFOV) has not been shown to be beneficial in the management of moderate-to-severe acute respiratory distress syndrome (ARDS). There is uncertainty about the actual pressure applied into the lung during HFOV. We therefore performed a study to compare the transpulmonary pressure (P L) during conventional mechanical ventilation (CMV) and different levels of mean airway pressure (mPaw) during HFOV. METHODS: This is a prospective randomized crossover study in a university teaching hospital...

BACKGROUND: Per oral endoscopic myotomy (POEM) is performed by accessing the submucosal space of the esophagus. This space may be impacted by prior interventions such as submucosal injections, dilations or previous myotomies. These interventions could make POEM more difficult and may deter surgeons during their initial experience. We sought to determine the impact of prior interventions on our early experience. METHODS: Prospective, single-center study of consecutive patients undergoing POEM...

Bougie or balloon dilation is a good short-term treatment for caustic esophageal strictures, although recurrence after dilation occurs in approximately 30% of these cases. Therefore, long-term treatment options are required in some cases, and endoscopic incisional therapy has been used for patients with an anastomotic stricture in the gastrointestinal tract. A 58-year-old woman presented with severe swallowing difficulty because of a caustic esophageal stricture, which was caused by accidental exposure to anhydrous acetic acid at infancy...

BACKGROUND AND AIMS: Although the rule of 3 is recommended to minimize the risk of perforation when esophageal dilation is performed using bougie dilators, there are no data to validate its use. Our aim was to investigate the association between the rule of 3 and adverse events (AEs) in esophageal dilation. METHODS: A retrospective chart review in patients who underwent esophageal bougie or balloon dilation between December 1991 and February 2013 at a tertiary hospital was performed...

BACKGROUND: Controversy remains whether preoperative pneumatic balloon dilation (PBD) influences the surgical outcome of laparoscopic esophagocardiomyotomy in patients with esophageal achalasia. The aim of this study was to evaluate whether preoperative PBD represents a risk factor for surgical complications and affects the symptomatic and/or functional outcomes of laparoscopic Heller myotomy with Dor fundoplication (LHD). METHODS: A retrospective chart review was conducted on a prospectively compiled surgical database of 103 consecutive patients with esophageal achalasia who underwent LHD from November 1994 to September 2014...

PURPOSE: This study aimed to evaluate the effectiveness of intravenous steroid pulse therapy following balloon dilatation for esophageal stenosis and stricture in children. METHODS: The study enrolled six children, including three with congenital esophageal stenosis and three with anastomotic strictures after surgery for esophageal atresia, all of whom were treated by balloon dilatation combined with high-dose intravenous methylprednisolone pulse therapy. Methylprednisolone was injected intravenously at a dose of 20 mg/kg/day for 2 days, starting from the day of dilatation, followed by 10 mg/kg/day for 2 days, for a total of 4 days...
