Patient Reported Outcomes and Objective Swallowing Assessments in a Multidisciplinary Dysphagia Clinic.

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.

Experience of nurse practitioners performing colonoscopy after endoscopic training in more than 1,000 patients.

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 51.5 %, African American 73.9 %) who underwent screening colonoscopies by three NPs. Cecal intubation was successful in 997 subjects (98.5 %). Mean adenoma detection rate was 35.6 %. 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.

Use of Esophageal pH Monitoring to Minimize Proton-Pump Inhibitor Utilization in Patients with Gastroesophageal Reflux Symptoms.

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.

Refractory gastroparesis can be successfully managed with endoscopic transpyloric stent placement and fixation (with video).

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.

Enhancing the quality of colonoscopy through split-dose bowel preparation.

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.

Jet injection of dyed saline facilitates efficient peroral endoscopic myotomy.

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 13.3 cm and the mean myotomy length was 9.9 cm. 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.
