Abstract
INTRODUCTION The prevalence of esophageal motor disorders (EMD) in PPI-refractory gastroesophageal reflux disease (GERD) is substantial. However, limited data exist on their impact on the efficacy of endoscopic treatments like anti-reflux mucosectomy (ARMS). This study aimed to evaluate the influence of EMD on ARMS efficacy in patients with PPI-refractory GERD. METHOD This single-center retrospective study enrolled patients with refractory GERD treated with ARMS-b (anti-reflux mucosectomy band-ligation). High-resolution esophageal manometry (HREM) was conducted before the procedure to identify EMD presence. The primary endpoint was treatment efficacy, defined as >50% improvement in GERD-HRQL score at 1 year. Secondary endpoints included PPI intake, symptom control, ARMS complications, and overall patient satisfaction at 12 months. RESULTS The study included 65 patients, with 41 (63.1%) showing EMD on HREM. Treatment efficacy was achieved by 33.8% (22) of patients, with 8 without EMD, 11 having isolated LES hypotonia, and 3 with both LES hypotonia and esophageal body motor disorder. No significant differences were observed between patients with and without EMD regarding the primary endpoint, PPI use, symptom control, or complications. Dysphagia developed in 52.3% (34) within 6 months, leading to esophageal dilatation in 15.3% (10). Two patients experienced acute hemorrhage, and one had perforation. CONCLUSION The presence of esophageal motor disorders does not seem to impact ARMS response, suggesting the technique's consideration in this population. Larger studies are essential for confirming these results and exploring treatment response and post-operative predictors.

Abstract
High-resolution manometry (HRM) with the Chicago Classification (CC) is the standard paradigm to define esophageal motility disorders. Functional lumen imaging probe (FLIP) panometry utilizes impedance planimetry to characterize esophageal compliance and secondary peristalsis. The aim of this study was to explore the clinical impact of FLIP panometry in addition to HRM. A retrospective chart review was performed on FLIP panometry cases utilizing the 322N catheter. Cases with prior foregut surgeries or botulinum injection within 6 months of FLIP panometry were excluded. EGJ-diameter and distensibility index (DI) and secondary contraction patterns at increasing balloon volumes were recorded. An EGJ-DI of ≥2.8 mm2/mm Hg at 60 mL was considered as a normal EGJ distensibility. CC diagnosis, Eckhardt score, Brief Esophageal Dysphagia Questionnaire, and clinical outcomes were obtained for each FLIP case. A total of 186 cases were included. Absent contractility and achalasia types 1 and 2 showed predominantly absent secondary contraction patterns, while type 3 had a variety of secondary contractile patterns on FLIP panometry. Among 77 cases with EGJ outflow obstruction (EGJOO), 60% had a low EGJ-DI. Among those with no motility disorder or ineffective esophageal motility on HRM, 27% had a low DI and 47% had sustained contractions on FLIP, raising concern for an esophageal dysmotility process along the achalasia and/or spastic spectrum. FLIP panometry often confirmed findings on HRM in achalasia and absent contractility. FLIP panometry is useful in characterizing EGJOO cases. Spastic features on FLIP panometry may raise concern for a motility disorder on the spastic spectrum not captured by HRM. Further studies are needed on FLIP panometry to determine how to proceed with discrepancy with HRM and explore diagnoses beyond the CC.

Abstract
INTRODUCTION Patients with esophageal symptoms often remain with an uncertain diagnosis after high-resolution manometry. AIM To determine the added value of concomitant pressure and symptom analysis in response to a rapid drink challenge (RDC). METHODS In consecutive patients referred for esophageal manometry, a RDC consisting in free drinking of 200 ml of water as quick as possible was performed after the standard single water swallows manometry. Both pressure patterns and usual symptoms induced by the RDC were analyzed. RESULTS A total of 1319 patients were included, (64.7% women, mean age 58.2 years, range 11-90). There were significant differences in pressure responses between patients with obstructive disorders, major hypercontractile disorders, esophageal hypomotility disorders and normal motility. The RDC provoked usual symptoms in 388 (29.4%) patients, associated with hyperpressive and obstructive patterns in 14.0% and 16.6%, respectively. Reproduction of dysphagia and regurgitation (not pain) was significantly associated with abnormal pressure responses during the RDC (p < 0.001 and p = 0.002, respectively). The RDC elicited both abnormal pressure patterns and symptoms in 6.2%, 1.6%, and 20.8% of patients with normal motility, ineffective esophageal motility, and esophago-gastric junction outflow obstruction, respectively. CONCLUSION Concomitant evaluation of symptoms and pressure responses to a RDC may increase the specificity of esophageal motor testing in patients with inconclusive diagnosis or normal esophageal motility.

Abstract
Background/Aims: Esophageal transit scintigraphy (ETS) is a useful tool for evaluating esophageal motility disorders, although conflicting results are seen due to lack of ideal bolus. Semisolid/solid boluses have shown superiority over liquid boluses, and the present study aims to establish the utility of in-house-prepared bolus in normal volunteers and its comparison with liquid bolus. Materials and Methods: Thirty-three healthy volunteers were selected for ETS with in-house-prepared semisolid bolus jelly containing 99mTc-sulfur colloid. Dynamic studies were acquired in anterior projection with single swallow for both supine and sitting positions. T90% esophageal emptying time (EET) was calculated for whole and three equally divided segments of esophagus and also done with liquid bolus on different day. Results: The median value of EET for semisolid bolus for whole esophagus in sitting and supine positions was 11.7 s (interquartile range [IQR]: 8.0–16.7) and 17.7 s (IQR: 12.0–33.0). EET of liquid bolus for whole esophagus in sitting and supine positions was 9.3 s (IQR: 8.0–13.3) and 13.0 s (IQR: 9.7–25.0), respectively. Significantly different EET for whole esophagus and lower one-third esophagus between sitting and supine positions was seen for semisolid (whole esophagus;P = 0.003, lower one-third esophagus; P = 0.025) and liquid boluses (whole esophagus; P = 0.032, lower one-third esophagus; P = 0.016). Comparing EET using semisolid and liquid boluses, only lower one-third esophagus in supine position showed significant difference (P = 0.033). Conclusions: In-house-prepared semisolid radiolabeled jelly is inexpensive, easy to prepare with good radiolabeling. Condensed dynamic images from semisolid bolus were better, sharper, and reproducible in comparison to liquid bolus without fragmentation. This study standardized semisolid bolus and verified its suitability for clinical use.

Abstract
Endoscopic intrasphincteric injection of Botox (ISIB) is used routinely for the treatment of achalasia esophagus and other spastic motor disorders. Studies show that the ISIB reduces the smooth muscle lower esophageal sphincter (LES) pressure. The esophageal hiatus, formed by the right crus of diaphragm, surrounds the cranial half of the LES and works like an external LES. We studied the effects of ISIB on the LES and hiatal contraction and gastroesophageal reflux (GER). Fourteen patients treated with ISIB were studied. Esophageal manometry-impedance recordings were performed before and after the ISIB. Hiatal contraction was assessed during tidal inspiration, forced inspiration, Müller's maneuver, and straight leg raise. In 6 subjects, the manometry were repeated 6-12 mo after the ISIB. The esophagogastric junction (EGJ) pressure was measured at end expiration (LES pressure) and at the peak of maneuvers (hiatal contraction). Transdiaphragmatic pressure (pdi; force of diaphragmatic contraction) was measured at the peak of forced inspiration. GER was measured from the impedance recordings. The EGJ pressure at end expiration (LES pressure) decreased significantly after the Botox injection. The peak EGJ pressure at tidal inspiration, forced inspiration, Müller's maneuver, and straight leg raise was also dramatically reduced by the ISIB. There was no effect of Botox on the pdi during forced inspiration. Seven of 10 subjects demonstrated GER during maneuvers following the ISIB. Six to 12 mo after ISIB, the LES and hiatal contraction pressure returned to the pre-ISIB levels. ISIB, in addition to decreasing LES pressure, paralyzes the esophageal hiatus (crural diaphragm) and induces GER.NEW & NOTEWORTHY The sphincter mechanism at the lower end of the esophagus comprises smooth muscle lower esophageal sphincter (LES) and skeletal muscle crural diaphragm (hiatus). Current thinking is that the endoscopic intrasphincteric injection of Botox (ISIB), used routinely for the treatment of achalasia esophagus, reduces LES pressure. Our study shows that ISIB, even though injected into the LES, diffuses into the hiatus and causes its paralysis. These findings emphasize the importance of esophageal hiatus as an important component of the antireflux barrier and that the ISIB is refluxogenic.

Abstract
BACKGROUND Opioid receptors are present in the esophagus, and chronic opioid therapy may be associated with esophageal dysfunction. Given the current opioid epidemic in the United States, the potential contribution of opioids to esophageal dysmotility is important from both public health and patient care perspectives. Therefore our aim is to investigate the potential contribution of opioids to dysphagia and the prevalence of major motor disorders in patients undergoing manometric evaluation. METHODS The anonymized electronic medical records of patients linked to their de-identified high-resolution manometry (HRM) studies were reviewed. The patients were grouped based on their opioid exposure history at the time of HRM: opioid-naïve and chronic daily users. The oral morphine milligram equivalent daily dose (MMED) of opioids was computed. KEY RESULTS: 10% of patients referred for esophageal HRM were taking opioid analgesics on a chronic daily basis, and they had a significantly higher prevalence of dysphagia than their opioid-naïve counterparts. The chronic daily opioid users displayed a significantly higher prevalence of achalasia type 3 (ACH3) and esophagogastric junction outflow obstruction (EGJOO) motility phenotypes. The MMED of opioids was a significant predictor of esophageal pressure metrics and motility diagnoses (P < 0.0001). CONCLUSIONS Chronic daily opioid intake is associated with impaired deglutitive LES relaxation and disorganized peristaltic sequence. While a minority of patients on chronic daily opioid therapy present with major esophageal motor disorders, they comprise nearly half of ACH3 and a third of EGJOO motility phenotypes.

Abstract
The utilization of high-resolution manometry (HRM) has enhanced our understanding and assessment of esophageal motor disorders. Moreover, the combination of impedance technology with HRM (HRIM) has further improved our knowledge of esophageal physiology and the clinical evaluation of dysmotility, thanks to the addition of accurate measurement of bolus transit. Areas covered. This paper provides an overview of current knowledge in the use of HRIM for the study of esophageal functional disorders by reporting mainly the results of many publications and several systematic reviews in this field. Expert opinion. HRIM has represented a relevant improvement in the assessment of esophageal motility and has required the development of new metrics, such as the esophageal impedance integral ratio, the bolus flow time, the nadir impedance pressure and the impedance bolus height, which increase the evaluation of esophageal bolus transit. An extension of impedance is represented by functional lumen imaging probe (FLIP), which determines the biophysical properties and the distensibility of the esophagus and permits to detect contractility patterns not seen on HRM alone. We eagerly wait for a new and fruitful iteration of the Chicago Classification, now in version 3.0, which can cover the ongoing clinical experience of HRIM.

Abstract
The best-defined primary esophageal motor disorder is achalasia. However, symptoms such as dysphagia, regurgitation and chest pain can be caused by other esophageal motility disorders such as Diffuse Esophageal Spasm (DES), Nutcracker Esophagus (NE) and the Hypertensive Lower Esophageal Sphincter (HTN-LES). Most patients with DES and HTN-LES who complain of dysphagia improve after a myotomy. Patients with NE whose main complaint is chest pain, often do not have relief of the pain and can even develop dysphagia as a consequence of the myotomy. POEM is a relatively new procedure, and there are no studies with long-term follow-up and no prospective and randomized trials comparing it to surgical myotomy. Overall, the key to success is based on a complete evaluation and a careful patient selection. The best results, regardless of the technique, are in fact obtained in patients with outflow obstruction and impaired esophageal emptying, a picture similar to achalasia.

Abstract
BACKGROUND High-resolution manometry has become the preferred choice of oesophagologists for oesophageal motor assessment, but the learning curve among trainees remains unclear. AIM To determine the learning curve of high-resolution manometry interpretation. METHODS A prospective interventional cohort study was performed on 18 gastroenterology trainees, naïve to high-resolution manometry (median age 32 ± 4.0 years, 44.4% female). An intake questionnaire and a 1-h standardised didactic session were performed at baseline. Multiple 1-h interpretation sessions were then conducted periodically over 15 months where 10 studies were discussed; 5 additional test studies were provided for interpretation, and results were compared to gold standard interpretation by the senior author. Hypothetical management decisions based on trainee interpretation were separately queried. Accuracy was compared across test interpretations and sessions to determine the learning curve, with a goal of 90% accuracy. RESULTS Baseline accuracy was low for abnormal body motor patterns (53.3%), but higher for achalasia/outflow obstruction (65.9%). Recognition of achalasia reached 90% accuracy after six sessions (P = 0.01), while overall accurate management decisions reached this threshold by the 4th session (P < 0.001). Based on our data, the threshold of 90% accuracy for recognition of any abnormal from normal pattern was reached after 30 studies (3rd session) but fluctuated. Diagnosis of oesophageal body motor patterns remained suboptimal; accuracy of advisability of fundoplication improved, but did not reach 90%. CONCLUSIONS High-resolution manometry has a steep learning curve among trainees. Achalasia recognition is achieved early, but diagnosis of other abnormal motor patterns and management decisions require further supervised training.

Abstract
BACKGROUND Multiple rapid swallows (MRS) during esophageal high resolution manometry (HRM) assess esophageal neuromuscular integrity by evaluating postdeglutitive inhibition and rebound contraction, but most reports performed only a single MRS sequence. We assessed patterns of MRS reproducibility during clinical HRM in comparison to a normal cohort. METHODS Consecutive clinical HRM studies were included if two separate MRS sequences (four to six rapid swallows ≤4 s apart) were successfully performed. Chicago Classification diagnoses were identified; contraction wave abnormalities were additionally recorded. MRS-induced inhibition (contraction ≤3 cm during inhibition phase) and rebound contraction was assessed, and findings compared to 18 controls (28.0 ± 0.7 year, 50.0% female). Reproducibility consisted of similar inhibition and contraction responses with both sequences; discordance was segregated into inhibition and contraction phases. KEY RESULTS Multiple rapid swallows were successfully performed in 89.3% patients and all controls; 225 subjects (56.2 ± 0.9 year, 62.7% female) met study inclusion criteria. Multiple rapid swallows were reproducible in 76.9% patients and 94.4% controls (inhibition phase: 88.0% vs 94.4%, contraction phase 86.7% vs 100%, respectively, p = ns). A gradient of reproducibility was noted, highest in well-developed motor disorders (achalasia spectrum, hypermotility disorders, and aperistalsis, 91.7-100%, p = ns compared to controls); and lower in lesser motor disorders (contraction wave abnormalities, esophageal body hypomotility) or normal studies (62.2-70.8%, p < 0.0001 compared to well-developed motor disorders). Inhibition phase was most discordant in contraction wave abnormalities, while contraction phase was most discordant when studies were designated normal. CONCLUSIONS & INFERENCES Multiple rapid swallows are highly reproducible, especially in well-developed motor disorders, and complement the standard wet swallow manometry protocol.

Abstract
Multipeaked waves (MPW) in the distal esophagus occur frequently in patients with esophageal spastic motor disorders and diabetes mellitus and are thought to represent repetitive esophageal contractions. We aimed to investigate whether the relative motion between a stationary pressure sensor and contracted peristaltic esophageal segment that moves with respiration leads to the formation of MPW. We mathematically modeled the effect of relative movement between a moving pressure segment and a fixed pressure sensor on the pressure waveform morphology. We conducted retrospective analysis of 100 swallow-induced esophageal contractions in 10 patients, who demonstrated >30% MPW on high-resolution manometry (HRM) during standardized swallows. Finally, using HRM, we determined the effects of suspended breathing and hyperventilation on the waveform morphology in 10 patients prospectively. Modeling revealed that relative movement between a stationary pressure sensor and a moving contracted segment, contraction duration, contraction amplitude, respiratory frequency, and depth of respiration affects the waveform morphology. Retrospective analysis demonstrated a close temporal association with the onset of second and subsequent contractions in MPW with respiratory phase reversals. Numbers of peaks in MPW and respiratory phase reversals were closely related to the duration of contraction. In the prospective study, suspended breathing and hyperventilation resulted in a significant decrease and increase in the MPW frequency as well as the number of peaks within MPW respectively. We conclude that MPW observed during clinical motility studies are not indicative of repetitive esophageal contraction; rather they represent respiration-related movement of the contracted esophageal segment in relation to the stationary pressure sensor.
