Achalasia is currently diagnosed according to the Chicago Classification v3.0 using high-resolution manometry and treatment focuses on disruption of the esophagogastric junction. A paper in this issue examines the utility of a timed barium esophagram with a 13 mm tablet challenge in differentiating achalasia from other diagnoses, finding 100% sensitivity. However, a large proportion of patients with non-achalasia dysphagia are also identified. Another paper in this issue proposes utilizing intraprocedure functional luminal imaging probe measurement during pneumatic dilation as a guide for upsizing dilations...

The manometry with water-perfused or solid-state catheters is the predominant diagnostic procedure to detect motility disorders of the esophagus. Another method is the manometry using gas-perfused catheters. Although the high-resolution manometry is the method of first choice, the conventional manometry with helium has some advantages: the simple and hygienically unproblematic use and the absence of any artefacts by the perfusion medium compared with water-perfusion, and the considerably lower costs compared with the solid-state catheters...

AIMS: Traditional technology to characterize urethral pressure changes during dynamic conditions is limited by slow response times or artifact-inducing withdrawal maneuvers. The 8F high-resolution manometry (HRM) catheter (ManoScan™ ESO, Covidien) has advantages of fast response times and the ability to measure urethral pressures along the urethral length without withdrawal. Our objective was to determine static and dynamic maximum urethral closure pressures (MUCPs) and resting functional urethral length (FUL) in women using HRM before and after transurethral bulking and compare results to other women who underwent midurethral sling (MUS)...

OBJECTIVE: In about one-third of brass instrumentalists, there are stress-related insufficiencies of velopharyngeal closure (VPC), i. e. the intraoral pressure exceeds the barrier formed by the VPC. Here, it was the aim to measure the VPC closing pressure while playing a trumpet and to evaluate the influence of a 30 minute stress sequence on the muscular activities in the VPC. MATERIAL AND METHODS: Sample: 6 healthy volunteers; task: to play the sound h1 for 5 seconds with 85 dB(A) and with 100 dB(A)...

Gastroesophageal reflux disease and esophageal dysmotility are prevalent in patients with advanced lung disease and are associated with graft dysfunction following lung transplantation. As a result, many transplant centers perform esophageal function testing as part of the wait-listing process but guidelines for testing in this population are lacking. The aim of this study is to describe whether symptoms of gastroesophageal reflux correlate with abnormal results on pH-metry and high-resolution manometry and can be used to identify those who require testing...

Esophageal achalasia is a primary smooth muscle motility disorder specified by aperistalsis of the tubular esophagus in combination with a poorly relaxing and occasionally hypertensive lower esophageal sphincter (LES). These changes occur secondary to the destruction of the neural network coordinating esophageal peristalsis and LES relaxation (plexus myentericus). There are limited data on segmental involvement of the esophagus in adults. We report on the case of a 54-year-old man who presented initially with complete aperistalsis limited to the distal esophagus...

Clinical history, questionnaire data and response to antisecretory therapy are insufficient to make a conclusive diagnosis of GERD in isolation, but are of value in determining need for further investigation. Conclusive evidence for reflux on oesophageal testing include advanced grade erosive oesophagitis (LA grades C and D), long-segment Barrett's mucosa or peptic strictures on endoscopy or distal oesophageal acid exposure time (AET) >6% on ambulatory pH or pH-impedance monitoring. A normal endoscopy does not exclude GERD, but provides supportive evidence refuting GERD in conjunction with distal AET <4% and <40 reflux episodes on pH-impedance monitoring off proton pump inhibitors...

Gastroesophageal reflux disease (GERD) is associated with different pulmonary diseases, including chronic obstructive pulmonary disease (COPD). Whether GERD is contributory to COPD severity remains unclear. This study aims to evaluate the contribution of GERD to the clinical manifestation of COPD based on ventilatory parameters and yearly clinical exacerbations. We studied 48 patients (56% females, age 66 years) with COPD. All patients underwent high-resolution manometry and esophageal pH monitoring. The patients were separated into two groups according to the presence of GERD...

BACKGROUND: lung transplantation (LTx) is a viable option for most patients with end-stage lung diseases. Esophageal motor disorders (EMD) are frequent in candidates for LTx, but there is very little data about changes in esophageal motility post-LTx. AIM: the aim of our study was to assess esophageal motor disorders by high resolution manometry (HRM) both pre-LTx and six months post-LTx in patients with and without organ rejection. STUDY: HRM (Manoscan®) was performed in 57 patients both pre-LTx and six months post-LTx...

BACKGROUND: The advent of the Chicago Classification for esophageal motility disorders allowed for clinically reproducible subgrouping of patients with achalasia based on manometric phenotype. However, there are limited data with regards to racial variation using high-resolution esophageal manometry (HREM). The aim of our study was to evaluate the racial differences in patients with achalasia diagnosed with HREM using the Chicago Classification. We evaluated the clinical presentation, treatment decisions and outcomes between blacks and non-blacks with achalasia to identify potential racial disparities...

With increased use of explosive devices in warfare, anal trauma is often seen coupled with more complex pelviperineal injury. While the associated mortality is high, casualties that survive are often left with disabling fecal incontinence from damage to the anosphincteric complex. After resolution of the acute insult, the initial evaluation mandates a thorough physical exam, including endoscopic evaluation with rigid proctoscopy and flexible sigmoidoscopy, as well as adjunctive testing, specifically anal manometry and endoanal ultrasound...

Achalasia cardia (AC) is a frequently encountered motility disorder of the esophagus resulting from an irreversible degeneration of neurons. Treatment modalities are palliative in nature and there is no curative treatment available for AC as of now. Significant advancements have been made in the management of AC over last decade. The introduction of high resolution manometry (HRM) and per-oral endoscopic myotomy (POEM) have strengthened the diagnostic and therapeutic armamentarium of AC. HRM allows for the characterization of the type of achalasia which in turn has important therapeutic implications...

BACKGROUND: Esophago-gastric junction (EGJ) outflow obstruction is of unclear significance. Rapid drink challenge (RDC) test is easy to perform during esophageal high resolution manometry. We aimed to assess the yield of RDC test in patients with EGJ outflow obstruction. METHODS: Manometry studies of patients with EGJ outflow obstruction according to the Chicago Classification v3.0 were retrospectively reviewed. Pan-esophageal pressurization (PEP), esophageal shortening, and pressure gradient across the EGJ were analyzed during RDC test (200-mL free drinking in sitting position) and compared according to the causes of EGJ outflow obstruction determined by charts review...

BACKGROUND: Repetitive, retrograde contractions (RRCs) in response to sustained esophageal distension are a distinct contractility pattern observed with functional luminal imaging probe (FLIP) panometry that are common in type III (spastic) achalasia. RRCs are hypothesized to be indicative of either impaired inhibitory innervation or esophageal outflow obstruction. We aimed to apply FLIP panometry to patients with post-fundoplication dysphagia (a model of esophageal obstruction) to explore mechanisms behind RRCs...
