Abstract
OBJECTIVE High-resolution esophageal manometry (HRM) is the gold standard for the diagnosis of esophageal motility disorders. HRM is typically performed in the office with local anesthesia only, and many patients find it unpleasant and painful. The aim of this study was to examine the effects of the use of a virtual reality (VR) headset on pain and anxiety outcomes in patients with dysphagia undergoing HRM. METHODS Patients with dysphagia were prospectively recruited and randomized to undergo HRM with and without VR distraction. Data collected included the State-Trait Anxiety Inventory-6 (STAI-6), the Short-Form McGill Pain Questionnaire, heart rate, and galvanic skin response (GSR) tracings. RESULTS Forty subjects completed the study, including 20 subjects in the intervention arm and 20 in the control arm. There was evidence of a significant positive effect of VR on calmness (p = 0.0095) STAI-6 rating, as well as on physiologic measures of pain with significantly decreased GSR rise time (p = 0.0137) and average rate of change of conductance change (p = 0.0035). CONCLUSION The use of VR during HRM catheter insertion increased calmness compared to control. Change of skin conductance was also reduced in the VR group, suggesting decreased physiologic pain. This study supports the consideration of the use of VR as a distraction tool to improve patient comfort during HRM. LEVEL OF EVIDENCE 2 Laryngoscope, 134:1118-1126, 2024.

Clin Transl Gastroenterol 2023; 14:e00571. [PMID: 36854056 PMCID: PMC10208713 DOI: 10.14309/ctg.0000000000000571] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/01/2022] [Accepted: 02/13/2023] [Indexed: 03/02/2023] Open
Abstract
INTRODUCTION While high-resolution manometry (HRM) is widely accepted as a safe procedure, no study has assessed the safety profile of HRM in clinical practice. This study aimed to determine the safety and tolerability of HRM and to investigate potential determinants of intolerability. METHODS We obtained HRM procedure reports, demographics, and clinical data (2005-2022) at a tertiary center using electronic chart review. Our primary outcome was HRM tolerability. Multivariable regression was performed to identify associations between the outcome and covariates including age, sex, race, and comorbidities. RESULTS A total of 5,107 patients (60.3% female) were included. Of them, 5,050 patients (98.9%) tolerated HRM well and 57 patients (1.1%) did not. Age had a statistically significant effect on tolerance: those younger than 18 years had more than a 5-fold increase in not tolerating HRM compared with those aged 18-79 years (5.77% vs 0.99%; odds ratio [OR] = 5.44, 95% confidence interval [CI] 1.60-18.45; P = 0.007), and those aged 80 years or older were also more likely to terminate HRM (2.43% vs 0.99%; OR = 2.56, 95% CI 1.13-5.76; P = 0.024). While prior foregut surgery had a significant effect on tolerance (OR = 8.06, 95% CI 2.29-28.39; P = 0.001), other factors of race, sex, body mass index, and psychological or cognitive disorders had no significant impact. No serious complications were identified. DISCUSSION HRM is safe and well-tolerated with approximately 1 in every 100 patients being unable to tolerate HRM. Intolerance was more commonly seen in children and seniors due to minor symptoms of discomfort without serious complications. These data points are crucial to counsel patients in whom HRM is being considered.

Abstract
Background Excessive inspiratory effort could translate into self-inflicted lung injury, thus worsening clinical outcomes of spontaneously breathing patients with acute respiratory failure (ARF). Although esophageal manometry is a reliable method to estimate the magnitude of inspiratory effort, procedural issues significantly limit its use in daily clinical practice. The aim of this study is to describe the correlation between esophageal pressure swings (ΔPes) and nasal (ΔPnos) as a potential measure of inspiratory effort in spontaneously breathing patients with de novo ARF. Methods From January 1, 2021, to September 1, 2021, 61 consecutive patients with ARF (83.6% related to COVID-19) admitted to the Respiratory Intensive Care Unit (RICU) of the University Hospital of Modena (Italy) and candidate to escalation of non-invasive respiratory support (NRS) were enrolled. Clinical features and tidal changes in esophageal and nasal pressure were recorded on admission and 24 h after starting NRS. Correlation between ΔPes and ΔPnos served as primary outcome. The effect of ΔPnos measurements on respiratory rate and ΔPes was also assessed. Results ΔPes and ΔPnos were strongly correlated at admission (R2 = 0.88, p < 0.001) and 24 h apart (R2 = 0.94, p < 0.001). The nasal plug insertion and the mouth closure required for ΔPnos measurement did not result in significant change of respiratory rate and ΔPes. The correlation between measures at 24 h remained significant even after splitting the study population according to the type of NRS (high-flow nasal cannulas [R2 = 0.79, p < 0.001] or non-invasive ventilation [R2 = 0.95, p < 0.001]). Conclusions In a cohort of patients with ARF, nasal pressure swings did not alter respiratory mechanics in the short term and were highly correlated with esophageal pressure swings during spontaneous tidal breathing. ΔPnos might warrant further investigation as a measure of inspiratory effort in patients with ARF. Trial registration: NCT03826797. Registered October 2016.

Different Methods to Improve the Monitoring of Noninvasive Respiratory Support of Patients with Severe Pneumonia/ARDS Due to COVID-19: An Update. J Clin Med 2022; 11:jcm11061704.

Abstract
The latest guidelines for the hospital care of patients affected by coronavirus disease 2019 (COVID-19)-related acute respiratory failure have moved towards the widely accepted use of noninvasive respiratory support (NIRS) as opposed to early intubation at the pandemic onset. The establishment of severe COVID-19 pneumonia goes through different pathophysiological phases that partially resemble typical acute respiratory distress syndrome (ARDS) and have been categorized into different clinical–radiological phenotypes. These can variably benefit on the application of external positive end-expiratory pressure (PEEP) during noninvasive mechanical ventilation, mainly due to variable levels of lung recruitment ability and lung compliance during different phases of the disease. A growing body of evidence suggests that intense respiratory effort producing excessive negative pleural pressure swings (Ppl) plays a critical role in the onset and progression of lung and diaphragm damage in patients treated with noninvasive respiratory support. Routine respiratory monitoring is mandatory to avoid the nasty continuation of NIRS in patients who are at higher risk for respiratory deterioration and could benefit from early initiation of invasive mechanical ventilation instead. Here we propose different monitoring methods both in the clinical and experimental settings adapted for this purpose, although further research is required to allow their extensive application in clinical practice. We reviewed the needs and available tools for clinical–physiological monitoring that aims at optimizing the ventilatory management of patients affected by acute respiratory distress syndrome due to severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection.

Abstract
BACKGROUND Several patients in gastroenterology practice present with esophageal symptoms, and in case of normal endoscopy with biopsies, high-resolution manometry (HRM) is often the next step. Our aim was to develop a European consensus on the clinical application of esophageal HRM, to offer the clinician guidance in selecting patients for HRM and using its results to optimize clinical outcome. METHODS A Delphi consensus was initiated with 38 multidisciplinary experts from 16 European countries who conducted a literature summary and voting process on 71 statements. Quality of evidence was evaluated using grading of recommendations assessment, development, and evaluation (GRADE) criteria. Consensus (defined as >80% agreement) was reached for 33 statements. RESULTS The process generated guidance on when to consider esophageal HRM, how to perform it, and how to generate the report. The Delphi process also identified several areas of uncertainty, such as the choice of catheters, the duration of fasting and the position in which HRM is performed, but recommended to perform at least 10 5-ml swallows in supine position for each study. Postprandial combined HRM impedance is considered useful for diagnosing rumination. There is a large lack of consensus on treatment implications of HRM findings, which is probably the single area requiring future targeted research. CONCLUSIONS AND INFERENCES A multinational and multidisciplinary group of European experts summarized the current state of consensus on technical aspects, indications, performance, analysis, diagnosis, and therapeutic implications of esophageal HRM.

Abstract
CONCLUSIONS Videofluoroscopy (VF) in the prone position can diagnose a range of esophageal pathologies in all age groups. These correlate with globus sensation in younger and middle-aged patients in prone and supine positions. Abnormal esophageal clearance appears to be associated with globus sensation in young and middle-aged persons, but not in the elderly. OBJECTIVES To assess the correlation between globus sensation and abnormal esophageal clearance by VF in relation to body position and to investigate age-related abnormal esophageal clearance, as well as to confirm the utility of VF in diagnosing globus sensation in patients. SUBJECTS AND METHODS This was a prospective study. In 72 patients with globus sensation and 33 controls, esophageal clearance was assessed by VF in the upright, supine, and prone positions, and transfer of barium through the esophagus was classified as normal, esophageal retention, esophageal reflux, or pharyngeal reflux. The detection rate of abnormal esophageal clearance was compared among all subjects by age. RESULTS In the upright position, VF detected no significant differences in the detection rate of abnormal esophageal clearance and reflux between the patients with globus sensation and controls; however, the detection rate of abnormal esophageal clearance was significantly higher in the prone than in the upright and supine positions (p<0.001), and in all positions was significantly higher among globus sensation patients (p<0.05). In the supine and prone positions, there were significantly higher detection rates of abnormal esophageal clearance in patients than in controls in the young group (p<0.05). Additionally in the prone position, there was a significantly higher detection rate of abnormal esophageal clearance and reflux in patients than in controls in the middle-aged group (p<0.05). In all positions, no significant differences were observed in the detection rate of abnormal esophageal clearance and reflux in the patients and controls in the elderly group.

Abstract
INTRODUCTION High-resolution manometry (HRM) of the esophagus is a new technique that provides a more precise assessment of esophageal motility than conventional techniques. Because HRM measures pressure events along the entire length of the esophagus simultaneously, clinical procedure time should be shorter because less catheter manipulation is required. According to manufacturer advertising, the new HRM system is more accurate and up to 50% faster than conventional methods. OBJECTIVE To test the hypothesis that clinical testing with HRM requires less procedural time than a standard water perfusion (WP) method. METHODS Forty-one consecutive patients were studied (20 underwent WP and 21 underwent HRM). Using time-motion analysis, the start and end times for each task associated with performing the study were recorded. Patient discomfort and study quality were also assessed by using five- and four-point qualitative scales, respectively. RESULTS Total procedure time was reduced on average by 25.6% in the HRM group (from 41.8 minutes with WP to 30.7 minutes with HRM, P<0.05). There was no significant difference in the discomfort scores reported by the study subjects and no difference in study quality. CONCLUSIONS HRM requires less time to complete than conventional manometry and should therefore shorten the wait-times of patients scheduled for esophageal manometry and have a significant impact on the cost of performing this commonly used clinical investigation.

Abstract
Motor dysfunction is an important cause of oropharyngeal dysphagia and distal esophageal symptoms. Minimally invasive surgical methods of managing Zenker diverticula and achalasia, important disorders associated with these presentations, continue to take center stage in the literature. Detection and characterization of hypomotility before antireflux surgery may be less important than systematically excluding achalasia, as the vague and variable presentations of this motor disorder become appreciated. The many processes that can mimic idiopathic achalasia continue to be exposed.
