ABSTRACT
BACKGROUND: Integrated relaxation pressure (IRP) calculation depends on the selection of a single gastric reference sensor. Variable gastric pressure readings due to sensor selection can lead to diagnostic uncertainty. This study aimed to examine the effect of gastric reference sensor selection on IRP measurement and diagnosis. METHODS: We identified high-resolution manometry (HRM) conducted between January and November 2017 with at least six intragastric reference sensors. IRP measurements and Chicago Classification 3.0 (CCv3) diagnoses were obtained for each of six gastric reference sensors. Studies were categorized as "stable" (no change in diagnosis) or "variable" (change in diagnosis with gastric reference selection). Variable diagnoses were further divided into "variable normal/dysmotility" (≥1 normal IRP measurement and ≥1 CCv3 diagnosis), or "variable dysmotility" (≥1 CCv3 diagnosis, only elevated IRP measurements). Bland-Altman plots were used to compare IRP measurements within HRM studies. KEY RESULTS: The analysis included 100 HRM studies, among which 18% had variable normal/dysmotility, and 10% had variable dysmotility. The average IRP difference between reference sensors was 6.7 mmHg for variable normal/dysmotility and 5.9 mmHg for variable dysmotility. The average difference between the proximal-most and distal-most sensors was -1.52 mmHg (lower limit of agreement -10.03 mmHg, upper limit of agreement 7.00 mmHg). CONCLUSIONS & INFERENCES: IRP values can vary greatly depending on the reference sensor used, leading to inconsistent diagnoses in 28% of HRM studies. Choosing the correct gastric reference sensor is crucial for accurate test results and avoiding misdiagnosis. Standardization of reference sensor selection or supportive testing for uncertain results should be considered.

BACKGROUND: Gastroesophageal reflux disease (GERD) is a common digestive complaint that can negatively affect patients' quality of life and have serious complications if inadequately treated. LOCAL PROBLEM: Facilitating prompt and efficient access to digestive care is imperative especially given the current burden of gastrointestinal diseases such as GERD. METHODS: A clinical team conducted a quality improvement study in which a nurse practitioner (NP) navigator performed a preconsultation chart review for patients with refractory GERD referred to an Esophagus Center between August and December 2018. INTERVENTIONS: Based on preconsultation chart review, the NP navigator arranged for diagnostic testing and follow-up. Days from consultation to testing completion and establishment of plan were tracked and compared with historic controls. The NP navigator documented time spent for chart review and care coordination. RESULTS: The median number of days from consultation to testing completion for patients who underwent NP navigation and required diagnostic testing (n = 26) was 33.5 as compared with 64.5 for historic controls who required testing but received usual care (n = 28) (p = .005). The median number of days from consultation to establishment of a management plan was 52 for patients who underwent NP navigation as compared with 97 for historic controls who did not (p = .005). The mean amount of time spent by the NP navigator for chart review and care coordination was 17.5 min (n = 30). CONCLUSIONS: Incorporation of NP navigators into gastroenterology practices offers a potential solution for timelier patient care delivery.

OBJECTIVES/HYPOTHESIS: Dysphagia encompasses a complex compilation of symptoms which often differ from findings of objective swallowing evaluations. The purpose of this investigation was to compare the results of subjective dysphagia measures to objective measures of swallowing in patients evaluated in a multidisciplinary dysphagia clinic. STUDY DESIGN: Prospective cohort study. METHODS: The study cohort included all patients evaluated in the multidisciplinary dysphagia clinic over 24 months. Participants were evaluated by a multidisciplinary team including a laryngologist, gastroenterologist, and speech-language pathologist. Evaluation included a videofluoroscopic swallowing study (VFSS), fiberoptic endoscopic evaluation of swallowing (FEES), and transnasal esophagoscopy (TNE). Data collected included diet (FOIS), Eating Assessment Tool (EAT-10) score, Reflux symptom index (RSI) score, and the findings of the VFSS exam. RESULTS: A total of 75 patients were included in the analysis. The average EAT-10 score was 16.3 ± 2.1, RSI was 21.4 ± 0.6, and FOIS score was 6.0 ± 1.33. VFSS revealed impairments in the oral phase in 40% of the cohort, pharyngeal in 59%, and esophageal in 49%. Abnormalities were noted in one phase for 32%, in 2 phases in 32%, and three phases in 18%. Patients with abnormal pharyngeal findings on VFSS had significantly higher EAT-10 scores (P = .04). Patients with abnormal oral findings on VFSS were noted to have significantly lower FOIS scores (P = .03). CONCLUSIONS: Data presented here demonstrate a relationship between patient reported symptoms and objective VFSS findings in a cohort of patients referred for multidisciplinary swallowing assessment suggesting such surveys are helpful screening tools but inadequate to fully characterize swallowing impairment. LEVEL OF EVIDENCE: 3 Laryngoscope, 131:1088-1094, 2021.

BACKGROUND: Esophageal baseline impedance (BI) shows promise for the diagnosis of gastroesophageal reflux disease (GERD), but means of acquisition and relevance to extra-esophageal manifestations of GERD (EE-GERD) remain unclear. In this study we aim to (I) evaluate concordance between BI as measured by 24-hour pH-impedance (pH-MII) and high-resolution impedance manometry (HRIM), and (II) assess relationship to potential EE-GERD symptoms. METHODS: In this prospective open cohort study, patients presenting for outpatient HRIM and pH-MII studies were prospectively enrolled. All patients completed the GERD-HRQL, NOSE, and respiratory symptom index questionnaire (RSI), plus questions regarding wheezing and dental procedures. HRIM and pH-MII were evaluated with calculation of BI. Correlations were assessed using either Pearson's correlation or Spearman's rank coefficients. RESULTS: 70 HRIM patients were enrolled, 35 of whom underwent pH-MII. There was no correlation between BI measurements as assessed by HRIM and pH-MII proximally, but there was moderate-weak correlation distally (r=0.34 to 0.5). Distal acid exposure time correlated with distal BI only for measurements by pH-MII (rho= -0.5 to -0.65), and not by HRIM. There was no relationship between proximal acid exposure time and proximal BI. There were no correlations when comparing proximal or distal BI measurements, acid exposure times, and impedance events to symptoms. CONCLUSIONS: Concordance between BI as measured by HRIM and pH-MII is poor, especially proximally, suggesting that these two methods are not interchangeable. There is no correlation between BI both distally/proximally and symptoms of either GERD/EE-GERD, suggesting that many symptoms are unrelated to acid or that BI is not an adequate marker to assess EE-GERD symptoms.
ABSTRACT
Background and study aims The demand for screening colonoscopy has continued to rise over the past two decades. As a result, the current workforce of gastroenterologists is unable to meet the needs for colorectal cancer (CRC) screening. Therefore, solutions are needed to improve this disparity, with non-physician endoscopists being a potential option. However, current literature on the performance of non-physicians in endoscopy is limited. The aim of this study was to assess the quality of colonoscopy performed by three gastrointestinal fellowship-trained nurse practitioners (NPs). Methods This was a retrospective study performed at a single tertiary academic medical center. Colonoscopies performed by three gastrointestinal-specialized NPs after having completed training of at least 140 supervised colonoscopies were reviewed for analysis. Inclusion criteria were patients undergoing colonoscopy for colorectal cancer screening purposes. Outcomes included colonoscopy quality indicators as defined by the American Society for Gastrointestinal Endoscopy/American College of Gastroenterology Taskforce (ASGE/ACG) Taskforce. Results The study included 1,012 subjects (mean age 56.2 years, female 51.5â%, African American 73.9â%) who underwent screening colonoscopies by three NPs. Cecal intubation was successful in 997 subjects (98.5â%). Mean adenoma detection rate was 35.6â%. Mean withdrawal time was 18.9 minutes. There were no adverse events including colonic perforations or delayed post-polypectomy bleeding. Conclusions Three fellowship-trained NPs in colonoscopy in the United States satisfied the quality indicators proposed by the ASGE/ACG Task force, demonstrating that adequately trained NPs can perform colonoscopy safely and effectively. With the demand for colonoscopy exceeding the supply, non-physicians could be part of the solution to meet the demands for CRC screening.
ABSTRACT
BACKGROUND: Many anti-nausea treatments are available for chronic gastrointestinal syndromes, but data on efficacy and comparative effectiveness are sparse. AIMS: To conduct a sectional survey study of patients with chronic nausea to assess comparative effectiveness of commonly used anti-nausea treatments. METHODS: Outpatients at a single center presenting for gastroenterology evaluation were asked to rate anti-nausea efficacy on a scale of 0 (no efficacy) to 5 (very effective) of 29 commonly used anti-nausea treatments and provide other information about their symptoms. Additional information was collected from the patients' chart. The primary outcome was to determine which treatments were better or worse than average using a t test. The secondary outcome was to assess differential response by individual patient characteristics using multiple linear regression. RESULTS: One hundred and fifty-three patients completed the survey. The mean efficacy score of all anti-nausea treatments evaluated was 1.73. After adjustment, three treatments had scores statically higher than the mean, including marijuana (2.75, p < 0.0001), ondansetron (2.64, p < 0.0001), and promethazine (2.46, p < 0.0001). Several treatments, including many neuromodulators, complementary and alternative treatments, erythromycin, and diphenhydramine had scores statistically below average. Patients with more severe nausea responded better to marijuana (p = 0.036) and diphenhydramine (p < 0.001) and less so to metoclopramide (p = 0.020). There was otherwise no significant differential response by age, gender, nausea localization, underlying gastrointestinal cause of nausea, and GCSI. CONCLUSIONS: When treating nausea in patients with chronic gastrointestinal syndromes, clinicians may consider trying higher performing treatments first, and forgoing lower performing treatments. Further prospective research is needed, particularly with respect to highly effective treatments.

BACKGROUND/AIMS: Current evidence suggests the presence of motility or functional abnormalities in one area of the gastrointestinal tract increases the likelihood of abnormalities in others. However, the relationship of gastroparesis to chronic constipation (slow transit constipation and dyssynergic defecation) has been incompletely evaluated. METHODS: We retrospectively reviewed the records of all patients with chronic dyspeptic symptoms and constipation who underwent both a solid gastric emptying scintigraphy and a high-resolution anorectal manometry at our institution since January 2012. When available, X-ray defecography and radiopaque marker colonic transit studies were also reviewed. Based on the gastric emptying results, patients were classified as gastroparesis or dyspepsia with normal gastric emptying (control group). Differences in anorectal and colonic findings were then compared between groups. RESULTS: Two hundred and six patients met the inclusion criteria. Patients with gastroparesis had higher prevalence of slow transit constipation by radiopaque marker study compared to those with normal emptying (64.7% vs 28.1%, P = 0.013). Additionally, patients with gastroparesis had higher rates of rectocele (88.9% vs 60.0%, P = 0.008) and intussusception (44.4% vs 12.0%, P = 0.001) compared to patients with normal emptying. There was no difference in the rate of dyssynergic defecation between those with gastroparesis vs normal emptying (41.1% vs 42.1%, P = 0.880), and no differences in anorectal manometry findings. CONCLUSIONS: Patients with gastroparesis had a higher rate of slow transit constipation, but equal rates of dyssynergic defecation compared to patients with normal gastric emptying. These findings argue for investigation of possible delayed colonic transit in patients with gastroparesis and vice versa.

BACKGROUND: Due to concerns about long-term PPI use in patients with acid reflux, we aimed at minimizing PPI use, either by avoiding initiating therapy, downscaling to other therapies, or introducing endoscopic or surgical options. AIMS: To examine the role of esophageal ambulatory pHmetry in minimizing PPI use in patients with heartburn and acid regurgitation. METHODS: Retrospective cohort analysis of patients with reflux symptoms, who underwent endoscopy, manometry, and ambulatory pHmetry to define the need for PPI. Patients were classified as: (1) never users; (2) partial responders to PPI; (3) users with complete response to PPI. Patients were then managed as: (1) PPI non-users; (2) PPI-initiated, and (3) PPI-continued. RESULTS: Of 286 patients with heartburn and regurgitation, 103 (36%) were found to have normal and 183 (64%) abnormal esophageal acid exposure (AET). In the normal AET group, 44/103 had not been treated and were not initiated on PPI. Of the 59 who had previously received PPI, 52 stopped and 7 continued PPI. Hence, PPI were avoided in 96/103 patients (93%). In the abnormal AET group, 61/183 had not been treated and 38 were initiated on PPI and 23 on other therapies. In the 122 patients previously treated with PPI, 24 were not treated with PPI, but with H2RAs, prokinetics, endoscopic, or surgical therapy. Hence, PPI therapy was avoided in 47/183 patients (26%). CONCLUSIONS: In patients with GER symptoms, esophageal pHmetry may avert PPI use in 50%. In the era of caution regarding PPIs, early testing may provide assurance and justification.

BACKGROUND: Gastric and esophageal dysmotility syndromes are some of the most common motility diagnoses, but little is known about their interrelationship. AIMS: The aim of our study was to determine if a correlation exists between gastric and esophageal dysmotility syndromes. METHODS: We reviewed the records of all patients who underwent both solid gastric emptying scintigraphy (GES) and high-resolution esophageal manometry (HRM) within a 2 year period, with both done between August 2012 and August 2017. All GESs were classified as either rapid, normal, or delayed. All HRMs were classified according to the Chicago Classification 3.0. Correlations were assessed using Fisher's exact test and multiple logistic regression. RESULTS: In total, 482 patients met inclusion criteria. Of patients with a normal, delayed, and rapid GES, 53.1, 64.5, and 77.3% had an abnormal HRM, respectively (p < 0.05 vs. normal GES). Likewise, patients with an abnormal HRM were more likely to have an abnormal GES (54.9 vs. 41.8%, p = 0.005). Multiple logistic regression showed abnormal GES [odds ratio (OR) 2.14], age (OR 1.013), scleroderma (OR 6.29), and dysphagia (OR 2.63) were independent predictors of an abnormal HRM. Likewise, an abnormal HRM (OR 2.11), diabetes (OR 1.85), heart or lung transplantation (OR 2.61), and autonomic dysfunction (OR 2.37) were independent predictors of an abnormal GES. CONCLUSIONS: The correlation between an abnormal GES and HRM argues for common pathogenic mechanisms of these motility disorders, and possibly common future treatment options. Clinicians should have a high index of suspicion for another motility disorder if one is present.

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. MATERIALS AND METHODS: We performed a retrospective review of consecutive patients referred for HREM at a single tertiary referral center from June 2008 through October 2012. All patients diagnosed with achalasia on HREM according to the Chicago Classification were included. Demographic, clinical and manometric data were abstracted. All studies interpreted before the Chicago Classification was in widespread use were reanalyzed. Race was defined as black or non-black. Patients who had missing data were excluded. Proportions were compared using chi-squared analysis and means were compared using the Student's t-test. RESULTS: A total of 1,268 patients underwent HREM during the study period, and 105 (8.3%) were manometrically diagnosed with achalasia (53% female, mean age: 53.8 ± 17.0 years) and also met the aforementioned inclusion and exclusion criteria. A higher percentage of women presented with achalasia in blacks as compared to whites or other races (P < 0.001). Non-blacks were more likely to present with reflux than blacks (P = 0.01), while blacks were more likely to be treated on the inpatient service than non-blacks (P < 0.001). There were no other significant differences noted in clinical presentation, treatment decisions and treatment outcomes among blacks and non-blacks. CONCLUSIONS: Our study highlights possible racial differences between blacks and non-blacks, including a higher proportion of black women diagnosed with achalasia and most blacks presenting with dysphagia. There is possibly a meaningful interaction of race and sex in the development of achalasia that might represent genetic differences in its pathophysiology. Further prospective studies are required to identify such differences.

BACKGROUND: Constipation and fecal incontinence (FI) are common and are often evaluated with anorectal manometry. Three-dimensional high-resolution anorectal manometry (HRAM) is a promising technology; however, implementation has been limited by lack of metrics and unclear clinical utility. AIM: To investigate the diagnostic utility of 3D HRAM compared to 2D HRAM. METHODS: Three-dimensional HRAM studies performed from April 2012 to October 2013 were identified and re-interpreted by two blinded investigators examining 3D function. Disagreements were resolved by a third investigator. Puborectalis (PR) visualization, focal defects, and dyssynergy were reported. Differences between groups were analyzed with Fisher's exact test. Discordance was analyzed with McNemar Chi-square test. RESULTS: Two hundred and twenty-one 3D HRAM studies were identified. Mean age and BMI were 52.2 ± 17.4 and 27.1 ± 7.5 years (81% female, 74% white). Most common indications for 3D HRAM were constipation (65%) and FI (28%). PR function was visualized in 81% (rest), 97% (squeeze), and 73% (strain). PR was visualized less often at rest in FI than constipation (68 vs. 85%, p = 0.007). Defects were identified twice as often in FI than constipation (19 vs. 10%, p = 0.113). Twenty-nine defects (86% anterior) were visualized on 3D HRAM. Inter-reader agreement was moderate for PR function (κ = 0.471), but fair for focal defects (κ = 0.304). CONCLUSIONS: PR function and focal defects can be visualized on 3D-HRAM with added diagnostic benefit compared to 2D. Fair inter-reader agreement for focal defects highlights the need for quantitative metrics.

BACKGROUND AND AIMS: Medical treatment options for gastroparesis are limited. Data from studies of botulinum toxin and surgical pyloroplasty suggest that disruption of the pylorus can result in symptomatic improvement in some patients with refractory gastroparetic symptoms. The aim of this study was to determine the clinical response to transpyloric stent (TPS) placement in patients with gastroparetic symptoms refractory to standard therapy. METHODS: Patients with gastroparesis refractory to medical treatment were referred for TPS placement for salvage therapy. Self-reported symptom improvement, stent migration rate, and pre- and post-stent gastric-emptying study results were collected. RESULTS: A total of 30 patients with refractory gastroparesis underwent 48 TPS procedures. Of these, 25 of 48 (52.1%) were performed in patients admitted to the hospital with intractable gastroparetic symptoms. Successful stent placement in the desired location across the pylorus (technical success) was achieved during 47 procedures (98%). Most (n = 24) stents were anchored to the gastric wall by using endoscopic suturing with a mean number of sutures of 2 (range 1-3) per procedure. Clinical response was observed in 75% of patients, and all inpatients were successfully discharged. Clinical success in patients with the predominant symptoms of nausea and vomiting was higher than in those patients with a predominant symptom of pain (79% vs 21%, P = .12). A repeat gastric-emptying study was performed in 16 patients, and the mean 4-hour gastric emptying normalized in 6 patients and significantly improved in 5 patients. Stent migration was least common (48%) when stents were sutured. CONCLUSION: TPS placement is a feasible novel endoscopic treatment modality for gastroparesis and improves both symptoms and gastric emptying in patients who are refractory to medical treatment, especially those with nausea and vomiting. TPS placement may be considered as salvage therapy for inpatients with intractable symptoms or potentially as a method to select patients who may respond to more permanent therapies directed at the pylorus.

BACKGROUND: Abnormalities of the upper esophageal sphincter (UES) on high-resolution esophageal manometry (HREM) have been observed in both symptomatic and asymptomatic individuals and are often interpreted as incidental findings of unclear clinical significance. AIMS: Our primary aims were: (1) to assess the frequency of UES abnormalities in consecutive patients referred for HREM studies; and (2) to characterize the demographics, clinical symptoms, and manometric profiles associated with UES abnormalities as compared with those with normal UES function. MATERIALS AND METHODS: We performed a retrospective study of 200 consecutive patients referred for HREM. Patients were divided into those with normal and abnormal UES function, including impaired relaxation (residual pressure >12 mm Hg), hypertensive (>104 mm Hg), and hypotensive (<34 mm Hg) resting pressure. Clinical and manometric profiles were compared. RESULTS: A total of 32.5% of patients had UES abnormalities, the majority of which were hypertensive (55.4%). Patients with achalasia were significantly more likely to have UES abnormalities as compared with normal UES function (57.2% vs. 42.9%, P=0.04), with the most frequent abnormality being a hypertensive UES (50%). In addition, patients with impaired lower esophageal sphincter (LES) relaxation (esophagogastric junction outflow obstruction or achalasia) were more likely to have an UES abnormality present as compared with those with normal LES relaxation (53.1% vs. 28.6%, P=0.01). When we assessed for treatment response among patients with achalasia, we found that subjects with evidence of UES dysfunction had significantly worse treatment outcomes as compared with those without UES abnormalities present (20% improved vs. 100%, P=0.015). This remained true even after adjusting for type of treatment received (surgical myotomy, per-oral endoscopic mytotomy, botulinum toxin injection, pneumatic dilatation, medical therapy, P=0.67) and achalasia subtype (P=1.00). CONCLUSIONS: UES abnormalities are a frequent finding on HREM studies, especially in patients with impaired LES relaxation, including both achalasia and esophagogastric junction outflow obstruction. Interestingly, the most common UES abnormality associated with achalasia was a hypertensive resting UES, despite the fact that achalasia is thought to spare striated muscle. Among patients with achalasia, we found a significant association between the lack of treatment response and the presence of UES dysfunction. The routine evaluation of UES function in patients referred for manometry may enhance our understanding of esophageal motility disorders and may yield important prognostic information, particularly in subjects with achalasia. Future prospective studies are needed to further delineate the underlying mechanism between UES dysfunction with achalasia and other esophageal motility disorders to predict treatment response and guide therapeutic treatment modalities.

Colonoscopy is a primary method for colorectal cancer screening, yet its efficacy as a screening tool is largely dependent on the quality of bowel preparation. An estimated 25% of patients undergoing colonoscopy have poor bowel preparations at the time of their procedure. There is empirical evidence to support that split-dose bowel preparations yield better bowel cleansing than day-prior bowel preparation regimens. The aim of this quality improvement project was to enhance the quality of colonoscopy at a large urban academic center through the use of split-dose bowel preparation. A total of 74 patients participated, with about half undergoing the current practice of day-prior bowel preparation and half undergoing the intervention of split-dose bowel preparation. Several procedural and patient outcome measures were collected and used for comparison to determine which bowel preparation was optimal for use in the practice setting. The findings revealed that split-dose bowel preparation resulted in better bowel cleansing, reduced recall intervals for the time to the next recommended colonoscopy, and improved patient tolerance, supporting its use in the practice setting to enhance the quality of colonoscopy.

BACKGROUND AND STUDY AIMS: Peroral endoscopic myotomy (POEM) is technically challenging and time consuming. Repeated injection of dyed saline during tunneling is performed to enhance the demarcation between the submucosal layer and the muscularis propria. This process requires exchanging the knife for a catheter to spray dyed saline and is time consuming. This study aimed to describe a new method of injecting dyed saline through an integrated water jet channel during POEM. PATIENTS AND METHODS: POEM was performed using a triangular tip knife. Repeated jet injection of saline mixed with indigo carmine was performed whenever the submucosal dissection plane became unclear. RESULTS: The study cohort consisted of nine patients (8 achalasia, 1 Jackhammer esophagus). All procedures were technically feasible and successful without any complications and resulted in the patients' Eckhardt's scores returning to normal. The mean submucosal tunnel length was 13.3âcm and the mean myotomy length was 9.9âcm. The mean procedure time was 127 minutes. CONCLUSION: The modified POEM technique with use of jet injection of dyed saline is simple and may render POEM easier and more efficient than the standard dissection method.

The FDA recently approved the use of the HPV quadrivalent vaccine, Gardasil, for the prevention of genital warts in males ages 9 through 26. This literature review seeks to examine men's knowledge of and interest in HPV vaccination as this could potentially affect vaccine uptake.
