Impact of patient position on esophageal motility disorders using high-resolution esophageal manometry with impedance (HREMI): supine versus upright swallows. Esophagus 2021; 18:880-888. [PMID: 33974190 DOI: 10.1007/s10388-021-00849-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/04/2021] [Accepted: 04/29/2021] [Indexed: 02/03/2023]
Abstract
BACKGROUND High-resolution esophageal manometry with impedance (HREMI) performed with supine patient positioning is used to evaluate patients for esophageal dysmotility. However, most patients experience symptoms related to esophageal dysmotility when eating or drinking upright. The aims of this study are to: (1) compare HREMI metrics in supine versus upright position; and (2) determine if upright position alters motility characterization of patients. METHODS HREMI of twelve wet swallows in supine position and five wet swallows in upright position were performed on normal subjects (NS) and consecutive patients. Chicago Classification v3.0 (CC) diagnoses were evaluated in the supine position and a modified version of the Chicago Classification system was used in the upright position using normative upright values for DCI and IRP. RESULTS DCI decreased in NS by 414 mmHg × cm × sec (p = 0.001) and patients by 613 mmHg × cm × sec (p < 0.001). IRP decreased in NS by 6.2 mmHg (p < 0.001) and patients by 4.6 mmHg (p < 0.001). The rate of successful bolus clearance decreased in the upright position in patients by 11% (p < 0.001), but no statistically significant differences were observed in NS. 82 of 200 patients (41%) had a change in CC diagnosis in the upright position. Bolus clearance in the upright position varied in patients depending on their diagnosis in the upright position. CONCLUSIONS Upright swallows had lower LES, IRP, DCI and UES pressures in both normal subjects and patients with decreased bolus clearance in patients. Upright positioning can alter esophageal motility patterns and enhance diagnostic yield. Thus, upright swallows supplement supine swallows to help characterize esophageal dysmotility.

Abstract
Esophageal high-resolution manometry (HRM) assesses esophageal motor function and is indicated both for evaluation of esophageal symptoms and before antireflux interventions. HRM studies are interpreted and esophageal motor diagnoses made according to the Chicago Classification, version 3.0 algorithm, which is based on ten 5 mL supine water swallows. However, this practice of single liquid swallows performed in the supine position does not reflect typical "real-life" swallowing, and may not reproduce the patient's presenting symptoms. Therefore, provocative maneuvers at HRM-beyond these 10 standard swallows-can afford additional insights into esophageal motor function with clinically significant implications, and represent areas of exciting investigation and innovation. Accordingly, the 2020 American College of Gastroenterology Guidelines on Esophageal Physiologic Testing conditionally recommend their inclusion in the HRM protocol. In this clinical review, we discuss the supporting data for and clinical utility of provocative maneuvers at HRM that include changes in body position or accessories (upright swallows, "bridge" position, straight leg raise, abdominal compression), bolus consistency (solid swallows, test meals, postprandial high-resolution impedance manometry), bolus frequency (multiple rapid swallows), the volume of bolus (rapid drink challenge/multiple water swallows), and the use of pharmacological agents.

Abstract
Establishing normative values of high-resolution esophageal manometry is necessary for accurate interpretation and comparison of measurements. In this systematic review, we aimed to summarize normal values for different esophageal high-resolution manometry systems. Moreover, we assessed the effect of body position, bolus consistency, and provocative maneuvers on these normative thresholds. We searched Medline, Embase, and the Cochrane Library from January 1st, 2006, to January 20th, 2020, for studies that reported normative data of high-resolution manometry in healthy volunteers. We assessed methodological quality of the included studies and planned a descriptive analysis. We analyzed data from 54 articles describing normative thresholds in high-resolution manometry using solid-state or water-perfused systems. Forty-six studies performed the manometry study in the supine position with liquid swallows, whereas sixteen studies described normative values in the upright position. Twelve studies assessed normative values for different bolus consistencies, and nine studies evaluated different provocative maneuvers. There is a considerable variety of normative values for esophageal high-resolution manometry depending on the equipment used and the protocols performed to obtain measurements. This should be taken into account when evaluating measurements in clinical practice and when comparing results of published research studies.

High-resolution manometry in the upright position could improve the manometric evaluation of morbidly obese patients with esophagogastric junction outflow obstruction. Neurogastroenterol Motil 2020; 32:e13924. [PMID: 32599674 DOI: 10.1111/nmo.13924] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/18/2019] [Revised: 05/26/2020] [Accepted: 05/28/2020] [Indexed: 01/01/2023]
Abstract
BACKGROUND Esophagogastric junction outflow obstruction (EGJOO) detected by manometry in the supine position is prevalent in patients with morbid obesity, but not all EGJOOs are clinically significant. We investigated whether including upright swallows during high-resolution manometry (HRM) could help identify non-clinically significant EGJOO in patients with morbid obesity. METHODS We performed a retrospective study of consecutive morbidly obese patients diagnosed with EGJOO by HRM from July 2012 through July 2018. The HRM protocol included 10 supine and five upright 5-mL water swallows. Endoscopy, esophagram, and computed tomography were performed to identify whether the patients should be diagnosed as having clinically significant EGJOO. KEY RESULTS A total of 230 patients with morbid obesity underwent HRM in the supine position during the study period. Fifty (21.7%) patients were diagnosed with EGJOO, among which 32 completed HRM both in the supine and upright positions. Only 8/32 patients were diagnosed with EGJOO in an upright position. Fewer artifacts were displayed in esophageal pressure topography in the upright position. None of the 32 patients could be diagnosed as clinically significant EGJOO based on all the examinations. Median esophageal gastric junction pressure, integrated relaxation pressure, and distal contractile integral were higher, and median distal latency was longer in the supine position compared with the upright position (all P < .05). CONCLUSIONS AND INFERENCES Esophagus manometry in the upright position could reduce EGJOO overdiagnosis in patients with morbid obesity. Prolongation of the HRM study with some swallows in the upright position could be recommended in obese patients.

Abstract
Background/Aims According to the Chicago classification version 3.0, high-resolution manometry (HRM) should be performed in the supine position. However, with the patient in the upright/sitting position, the test could more closely simulate real-life behavior and may be better tolerated. We performed a systematic review of the literature to search whether the manometric variables and the final diagnosis are affected by positional changes. Methods A literature search was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. Studies published in English that compared HRM results in different body positions were included. Moreover, the change in diagnosis of esophageal motility disorders according to the shift of body position was investigated. Results Seventeen studies including 1714 patients and healthy volunteers met the inclusion criteria. Six studies showed a significant increase in lower esophageal sphincter basal pressure in the supine position. Integrated relaxation pressure was significantly higher in the supine position in 10 of 13 studies. Distal contractile index was higher in the supine position in 9 out of 10 studies. One hundred and fifty-one patients (16.4%) out of 922 with normal HRM in the supine position were diagnosed with ineffective esophageal motility (IEM) when the test was performed in the upright position (P < 0.001). Conclusions Performing HRM in the upright position affects some variables and may change the final manometric diagnosis. Further studies to determine the normal values in the sitting position are needed.

Normative Values for Esophageal Motility Assessed in the Physiological Seated Position for 16-Channel Water Perfused High-resolution Esophageal Manometry System and Postural Variations in Healthy Volunteers. J Neurogastroenterol Motil 2020; 26:61-66.

Abstract
Background/Aims Consensus guidelines for performance and analysis of high-resolution esophageal manometry (HREM) recommend use of equipment, population and posture specific normative values. To provide normative values for Chicago classification (CC) metrics in the physiological seated position for a 16-channel water perfused system (Dentsleeve HREM catheter, Advanced Manometry Systems, Melbourne, Australia) widely used in India and other countries with limited access to solid-state equipment. The results are compared with published CC metrics in supine position done using the same system and volunteers. Methods HREM tracings of ten 5 mL water swallows in sitting posture were acquired in healthy volunteers and normative values for CC version 3.0 metrics calculated. Individual swallows were paired with previously reported supine swallows for postural variations (Wilcoxon sign rank test) and concordance of CC diagnoses (Pearson coefficient). Results Analysis of 530 sitting posture water swallows (53 subjects) and comparison with their supine data revealed significantly higher integrated relaxation pressure (IRP; median 6.7 mmHg vs 6.1 mmHg) but lower distal latency (DL; mean 6.3 seconds vs 6.8 seconds) and distal contractile integral (DCI; mean 1224 mmHg sec cm vs 1456 mmHg sec cm). Sitting posture normal was defined as: IRP < 13.9, DL > 4.5, and DCI = 115–4500 (absent contractility: DCI < 30). CC diagnoses concordance using posture-specific cut-offs was moderate (k = 0.47). Conclusions This paper provides normative values for the Advanced Manometry Systems 16-channel water perfused system in the physiological seated position for CC metrics. Our findings of higher IRP and lower DCI in sitting posture than previously reported supine CC cut-offs, confirm the need to use posture-specific cut-offs for reporting HREM tracings.

Clin Gastroenterol Hepatol 2019; 17:2218-2226.e2. [PMID: 30708108 PMCID: PMC6663640 DOI: 10.1016/j.cgh.2019.01.024] [Citation(s) in RCA: 57] [Impact Index Per Article: 11.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/01/2018] [Revised: 01/10/2019] [Accepted: 01/18/2019] [Indexed: 12/12/2022]
Abstract
BACKGROUND & AIMS Under the Chicago Classification of esophageal motility disorders, esophagogastric junction outflow obstruction (EGJOO) includes a varied clinical spectrum that results in diagnostic and management difficulties. We aimed to demonstrate that including upright swallows during high-resolution manometry (HRM) helps identify patients with clinically significant EGJOO. METHODS We performed a retrospective study of consecutive patients diagnosed with EGJOO on HRM from January 2015 through July 2017. HRM studies included 10 supine and 5 upright 5-ml liquid swallows. HRM values, esophagrams, and patient-reported outcomes were evaluated to identify factors associated with objective EGJOO (defined by esophagram) and symptomatic dysphagia (brief esophageal dysphagia questionnaire scores, >10). RESULTS Of the 1911 patients who had HRM during the study period, 16.2% (310) were diagnosed with EGJOO; 155 patients completed an esophagram and 227 completed the brief esophageal dysphagia questionnaire. Of these patients, 30.3% (47/155) had radiographic evidence of EGJOO and 52.4% (119/227) had symptomatic dysphagia. The median upright integrated relaxation pressure for patients with radiographic evidence of EGJOO or symptomatic dysphagia was higher than for patients without. An upright integrated relaxation pressure >12 mmHg identified patients with radiographic evidence of EGJOO with 97.9% sensitivity and 15.7% specificity; for symptomatic dysphagia these values were 88.2% and 23.1%, respectively. CONCLUSION An upright integrated relaxation pressure of >12 mmHg identifies patients with clinically significant esophageal outflow obstruction or dysphagia with a high level of sensitivity. This simple manometric maneuver (upright swallows) should be added to the standard manometric protocol.
