A comparative needle study: EUS-FNA procedures using the HD ProCore(™) and EchoTip(®) 22-gauge needle types.

The specific needle sizes/types used in performing endoscopic ultrasound-guided fine needle aspirations (EUS-FNA) vary. The HD ProCore(™) is a 22-gauge beveled needle allowing for core biopsy along with aspiration material. In this study we compare this needle with a standard 22-gauge needle. Between April 1, 2011 and November 15, 2011, 18 patients undergoing EUS-FNA using the HD ProCore(™) needle were compared to a control group of 18 cases using the standard 22-gauge needle. Smears were assessed for: three-dimensional clusters, thick obscuring clusters, monolayer sheets, cellularity, crowded obscuring single cells, blood, and nuclear staining. Cell blocks were assessed for cellularity and presence of diagnostic material. Records were reviewed for the overall adequacy, number of FNA passes, and patient follow-up. Overall, the two needle groups demonstrated similar results for the cytology parameters, amount of diagnostic cell block material, adequacy, and accuracy. The mean number of passes to achieve adequacy varied between the groups [2.94 for the standard 22-gauge needle group versus 2.11 for the beveled needle group (P=0.03)] with no meaningful difference in case duration between needle groups. No complications were reported. The beveled EUS needle affords similar cytologic interpretability, adequacy, diagnostic accuracy, and amount of cell block material as a standard needle. There was a statistically significant trend toward fewer passes to achieve adequacy with the beveled EUS-FNA needle. Therefore, the EUS-FNA needle with a lateral bevel is a diagnostically similar alternative to standard endoscopy needles, the possibility that this beveled needle may improve per pass adequacy requires further verification.

Self-expanding metal stents (SEMS) for preoperative biliary decompression in patients with resectable and borderline-resectable pancreatic cancer: outcomes in 241 patients.

BACKGROUND AND AIM: Obstructive jaundice caused by distal biliary obstruction can present in up to 70 % of patients with localized cancer of the head of the pancreas. The aim of this study was to report our experience in using self-expanding metal stents (SEMS) for preoperative biliary decompression in patients with resectable and borderline resectable carcinoma of the pancreatic head. METHODS: We performed a retrospective study evaluating patients from two tertiary referral centers. Two-hundred and forty-one patients with resectable and borderline resectable pancreatic carcinoma underwent ERCP with metal biliary stent placement between September 2006 and August 2011. We assessed the effectiveness of SEMS to adequately decompress the biliary tree, procedural success, patient survival, stent patency, and stent-related complications. RESULTS: Two-hundred and forty-one patients were evaluated [123 male, mean age (± SD) 67.4 ± 9.8 years; resectable 174, borderline resectable 67]. Patients with borderline-resectable cancer underwent neoadjuvant therapy and restaging before possible curative surgery. Successful placement of a metal biliary stent was achieved in all patients and improved jaundice. Patients were followed for mean duration of 6.3 months. The overall survival was 49 % at 27 months. Fourteen (5.8 %) patients experienced stent occlusion; the mean time to stent occlusion was 6.6 (range 1-20) months. Immediate complications included: post-ERCP pancreatitis (n = 14), stent migration (n = 3), and duodenal perforation (n = 3). Long-term complications included stent migration (n = 9) and hepatic abscess (n = 1). A total of 144/174 patients deemed to have resectable cancer at time of diagnosis underwent curative surgery. Due to disease progression or the discovery of metastasis after neoadjuvant therapy, only 22/67 patients with borderline-resectable cancer underwent curative surgery. CONCLUSIONS: SEMS should be considered for patients with obstructive jaundice and resectable or borderline resectable pancreatic cancer, especially if surgery is not planned immediately as a result of preoperative chemoradiation. These stents appear to be safe and effective.

Placement of fully covered self-expandable metal stents in patients with locally advanced esophageal cancer before neoadjuvant therapy.

BACKGROUND: Most patients with locally advanced esophageal cancer requiring neoadjuvant therapy have significant dysphagia. OBJECTIVE: To report our experience in using a fully covered self-expandable metal stent (FCSEMS) to treat malignant dysphagia and for maintenance of nutritional support during neoadjuvant therapy. DESIGN: Retrospective study. SETTING: Two tertiary-care referral centers. PATIENTS: This study involved 55 patients with locally advanced esophageal cancer (50 adenocarcinoma, 5 squamous cell carcinoma). Forty-three patients were men, and the mean age was 65.8 years. INTERVENTION: EUS followed by FCSEMS placement. MAIN OUTCOME MEASUREMENTS: Procedural success, dysphagia scores, patient weights, stent migration, and stent-related complications. RESULTS: All stents were successfully placed. Tumors were located in the middle esophagus (n = 10) and distal esophagus (n = 45). The mean dysphagia score obtained at 1 week after stent placement had improved significantly from baseline (2.4 and 1, respectively; P < .001). Patients maintained their weights at 1 month follow-up when compared with baseline (153 and 149 pounds, respectively; P = .58). Immediate complications included chest discomfort in 13 patients; 2 patients required stent removal because of intractable pain. One patient had stent removal because of significant acid reflux. Stent migration occurred at some point in 17 of 55 patients (31%). There was a delayed perforation in 1 patient. Because of disease progression or the discovery of metastasis after neoadjuvant therapy, only 8 of 55 patients underwent curative surgery. LIMITATIONS: Retrospective study. CONCLUSION: Placement of FCSEMSs in patients with locally advanced esophageal cancer significantly improves dysphagia and allows for oral nutrition during neoadjuvant therapy. FCSEMSs appear to be effective for palliating dysphagia. Migration was not associated with injury or harm to the patient and usually represented a positive response to neoadjuvant therapy. Few patients undergoing stenting in this situation ultimately undergo surgery because of disease progression or poor operative candidacy.

A retrospective study of nurse-assisted propofol sedation in patients with amyotrophic lateral sclerosis undergoing percutaneous endoscopic gastrostomy.

BACKGROUND: Percutaneous endscopic gastrostomy (PEG) placement is standard in the care of patients with amyotrophic lateral sclerosis (ALS) unable to maintain adequate oral nutrition. This has been performed using conscious sedation with narcotics/benzodiazepines. However, recent studies suggest that propofol sedation is superior for other endoscopic procedures. In addition, endoscopic PEG placement is not recommended for patients with ALS with a forced vital capacity (FVC) <50%. The authors postulated that nurse-administered propofol sedation (NAPS) with the addition of bilevel positive airway pressure (BiPAP) would be superior to standard sedation with midazolam/fentanyl (M/F) in all patients with ALS regardless of FVC. Here the authors review their retrospective experience of PEG placements in patients with ALS using propofol ± BiPAP vs traditional sedation ± BiPAP. RESULTS: Thirty-one patients received M/F, and 29 received NAPS. BiPAP was used more often in the NAPS group (24/29 NAPS vs 6/31 M/F respectively, P < .0001). Twenty-nine of 31 PEG placements in the M/F group and 27 of 29 PEG placements in the NAPS group were successful. Seven desaturation events occurred to <90% in the M/F group compared with 1 desaturation event in the NAPS group (P = .05). No other complications were noted. CONCLUSION: PEG placement can be performed safely in patients with ALS with FVC <50% using NAPS with BiPAP.

A retrospective correlation of percutaneous feeding tube stoma length in sitting and supine positions compared with body mass index.

BACKGROUND: Accurate knowledge of stoma tract length is important to prevent gastric ulcer formation, buried bumper syndrome, and peristomal leakage/infection. Current guidelines suggest 0.5-1.0 cm of play between the skin and external bolster. The aim of this study was to determine if stoma tract length changes from supine and sitting position and if this change is related to BMI. METHODS: Patients undergoing percutaneous feeding tube change from November 2006 to September 2009 were enrolled. Correlations were made between BMI and stoma tract length in both sitting and supine positions. RESULTS: Twenty-eight patients (24 percutaneous endoscopic gastrostomy [PEG], 4 direct percutaneous jejunal feeding tube) were included; 19 (68%) were female. The mean ± SD stoma length was 3.6 ± 0.9 cm in the supine position and 4.9 ± 1.4 cm in the sitting position. The mean ± SD stoma length change from supine to sitting position was 1.53 ± 0.9 cm. Mean ± SD BMI was 21.2 ± 4.5 (range, 14.9-33.8). Stoma length in the supine position (r = 0.65, P = .0002) and sitting position (r = 0.6, P = .0009) was strongly correlated with BMI. Change in stoma tract length was correlated with BMI (r = 0.43, P = .02). CONCLUSION: Stoma tract length is strongly correlated with BMI in both the sitting and supine positions. PEG stoma tract length changes significantly from the supine and sitting position. To prevent complications, most patients should have a longer distance set between internal and external bolsters than is recommended.

Combined ERCP and EUS in one session is safe in elderly patients when compared to non-elderly patients: outcomes in 206 combined procedures.

AIMS: Combined ERCP/EUS is becoming common. Combined procedures are frequently performed in elderly patients. We hypothesized that combined ERCP/EUS is equally safe in elderly patients when compared to non-elderly patients. METHODS: This was a retrospective single-center study comparing outcomes in elderly and non-elderly patients undergoing combined ERCP/EUS. RESULTS: A total of 206 patients were included. Mean age was 65 years (M:F 113:93); 99 were <65 years and 107 were >65. Indications included: jaundice (51%), abnormal imaging (17%), pancreatic tumor (11%), abdominal pain (5%), stent placement/change (5%), acute or chronic pancreatitis (5%), other (6%). Fine needle aspiration was performed in 134 (65%) procedures. Malignancy was identified in 142/206 (69%) patients. Mean Charlson Comorbidity Index (CCI) was 7.5 (range 0-22). Among patients <65 years old there were no immediate adverse events. Long-term adverse events in patients <65 (within 30 days) included cholangitis (1), increasing abdominal pain (4), post-ERCP pancreatitis (3), nausea/vomiting (1), increasing fatigue (1), and increasing jaundice (1). A subgroup analysis among geriatric patients (>65) was performed. Mean CCI was 8.2 (range 0-22). There was one immediate adverse event of non-sustained ventricular tachycardia in a 76-year old. Long-term adverse events included increasing fatigue (1), nausea/vomiting (2), increasing abdominal pain (2), urosepsis (1), fever (2) and dehydration (1). There were no statistically significant differences in outcomes in elderly compared to non-elderly patients. Elderly patients had higher CCI scores (p = 0.04). CONCLUSION: Combined ERCP/EUS in one session is safe in the general population and elderly patients, with no more adverse events than in non-elderly patients.

Duodenal and colonic stent placement with 0.025″ and 0.035″ guidewires is equally safe and effective.

BACKGROUND: The overwhelming majority of reported duodenal and colonic SEMS placements in the literature have used the 0.035″ guidewire almost to the exclusion of guidewires of other diameters. AIMS: The purpose of this study was to compare technical and clinical outcomes in patients undergoing duodenal or colonic SEMS placement with 0.025″ or 0.035″ guidewires. METHODS: This was a retrospective study to compare technical and clinical outcomes and complications of patients receiving duodenal or colonic SEMS placement with a 0.035″ guidewire to those undergoing placement with a 0.025″ guidewire. RESULTS: A total of 34 duodenal and 30 colonic stent placement procedures were performed in 59 patients. Technical success was achieved in all duodenal stent placement procedures. The difference in mean GOOSS score increase after stent placement was not statistically significant between the 0.035″ and 0.025″ guidewire groups (P = 0.49). Complications were not statistically significantly different between the two groups undergoing gastroduodenal stenting. Technical and clinical success was achieved in all colonic stent placement procedures. There were no statistically significant differences in complication rates between the two groups undergoing colonic stenting. Procedure times were not significantly different using either wire type. CONCLUSIONS: Our study shows that both 0.035″ and 0.025″ guidewires were equally effective with regards to technical success, clinical success, and with regards to the development of complications.

Incidental pancreatography via ERCP in patients with anomalous pancreaticobiliary junction does not result in pancreatitis in a North American population.

INTRODUCTION: Anomalous pancreaticobiliary junction (APBJ) is the term used to describe anatomical variants of pancreatic and biliary ductal junctional anatomy. Patients have junction of the pancreatic and bile ducts located outside the duodenal wall, forming a long common channel. We report our findings and clinical outcomes in a North American series of patients with APBJ undergoing ERCP. METHODS: Retrospective chart review. RESULTS: We reviewed 2,218 ERCP performed on 1,050 patients. Twelve patients (1.1%) with APBJ were identified (5F, 7M). No patient had an associated choledochocele. Mean age was 53.2 (range 17-85). A total of 43 ERCP procedures were performed on these 12 patients. All patients experienced passive pancreatography. No patient developed post-ERCP pancreatitis. Only one patient had a history of antecedent pancreatitis. CONCLUSIONS: In North American patients undergoing ERCP, 1.1% of patients had APBJ. Our study population was predominately Caucasian, male, and in all but one patient lacked a history of prior pancreatitis. No patient developed post-ERCP pancreatitis. This suggests that APBJ may have different clinical manifestations in a North American population when compared to Asian populations.

Endoscopic findings in patients presenting with dysphagia: analysis of a national endoscopy database.

Dysphagia is a common problem and an indication for upper endoscopy. There is no data on the frequency of the different endoscopic findings and whether they change according to demographics or by single versus repeat endoscopy. To determine the prevalence of endoscopic findings in patients with dysphagia and whether findings differ in regard to age, gender, ethnicity, and repeat procedure. This was a retrospective study using a national endoscopic database (CORI). A total of 30,377 patients underwent esophagogastroduodenoscopy (EGD) for dysphagia of which 4,202 patients were repeat endoscopies. Overall frequency of endoscopic findings was determined by gender, age, ethnicity, and single vs. repeat procedures. Esophageal stricture was the most common finding followed by normal, esophagitis/ulcer (EU), Schatzki ring (SR), esophageal food impaction (EFI), and suspected malignancy. Males were more likely to undergo repeat endoscopies and more likely to have stricture, EU, EFI, and suspected malignancy (P = 0.001). Patients 60 years or older had a higher prevalence of stricture, EU, SR, and suspected malignancy (P < 0.0001). Esophageal stricture was most common in white non-Hispanic patients compared to other ethnic groups. In patients undergoing repeat EGD, stricture, SR, EFI, and suspected malignancy were more common (P < 0.0001). The prevalence of endoscopic findings differs significantly by gender, age, and repeat procedure. The most common findings in descending order were stricture, normal, EU, SR, EFI, and suspected malignancy. For patients undergoing a repeat procedure, normal and EU were less common and all other abnormal findings were significantly more common.

Evaluation of gastropexy and stoma tract maturation using a novel introducer kit for percutaneous gastrostomy in a porcine model.

BACKGROUND: Fluoroscopic placement of percutaneous gastrostomy (PG) requires the use of T-bar fasteners to affix the stomach to the anterior abdominal wall; the effect of T-fasteners on stoma tract maturation is unknown. The authors studied PG stoma tract maturation, comparing PG + gastropexy with standard percutaneous endoscopic gastrostomy (PEG). METHODS: Sixteen pigs underwent PG placement using a novel introducer kit. Three absorbable suture T-fasteners were placed around the stoma site, and PG was placed using the Russell method. A standard PEG was then placed using the Ponsky pull method, allowing each animal to serve as its own control. Gross and histopathological integrity of stoma tract formation was assessed at 1-3 weeks. RESULTS: At sacrifice, all PGs were intact with no evidence of infection, disruption, or significant leakage. Stoma tracts of all test and control sites were robust and histologically mature at all time points. Stoma tract diameters were also similar between test and control PGs (mean ± SEM: control 13.1 ± 0.7 mm, test 12.1 ± 0.4 mm; P = .2, n = 15). Histopathological evaluation demonstrated a generally comparable tissue response between test and control PGs, with slight decreases in fibrosis noted in test compared to control sites (P = .02, n = 15). CONCLUSIONS: Stoma tract maturation of PG with gastropexy provides similar results to standard PEG. Stoma tracts were mature at 1 week regardless of placement method. Placement and performance of PG using the new introducer kit with novel T-fasteners and absorbable suture yields effective gastric anchoring and has similar ease of use as standard PEG placement.

Comorbidities, sphincterotomy, and balloon dilation predict post-ERCP adverse events in PSC patients: operator experience is protective.

BACKGROUND: Primary sclerosing cholangitis (PSC) is a chronic cholestatic disease. Interventional ERCP improves survival in PSC patients. AIMS: To describe the frequency and risk factors for post-ERCP adverse events in patients with PSC via multivariate analysis. METHODS: Retrospective cohort study included patients with a diagnosis of PSC who underwent ERCP at academic institutions between February 2000 and October 2009. Demographis, co-morbid conditions, antibiotic use, cannulation method, ERCP maneuvers and 30-day post-ERCP adverse events were collected. Multivariate analysis was performed using logistic regression. RESULTS: A total of 185 procedures were performed on 75 PSC patients (58 M,17 F). Seven endoscopists performed ERCPs. Comorbidies included ulcerative colitis (44%, n = 33), Crohn's disease (12%, n = 9 patients), Cirrhosis (8%, n = 6 patients) and autoimmune hepatitis (2.7%, n = 2). Cannulation was achieved using dye-free guidewire cannulation techniques in 139/185 procedures (76%) and with contrast-based techniques in 46/185 procedures (24%). Thirty-day post-ERCP adverse events included post-ERCP pancreatitis (5%, n = 9, cholangitis (1%, n = 2), acute cholecystitis (0.5%, n = 1), stent occlusion (0.5%, n = 1), stent migration (0.5%, n = 1), and bile leak (0.5%, n = 1). In the multivariate analysis, associations with specific endoscopists who performed the procedure (P = 0.01), biliary dilation (P = 0.02), sphincterotomy (P = 0.03), presence of cirrhosis (P = 0.05), Crohn's disease (P < 0.001), and autoimmune hepatitis (P < 0.001) significantly predicted a complication following ERCP. Gender, stenting during procedure, presence of a dominant stricture, and cholangitis were not predictive for post-ERCP adverse events. CONCLUSIONS: Factors predicting 30-day post-ERCP adverse events included certain co-morbid conditions, the endoscopist ERCP volume, maneuvers during ERCP including dilation and sphincterotomy. Stenting was not associated with adverse events.

Endoscopic retrograde cholangiopancreatography for non-gastroenterologists: what you need to know.

Endoscopic retrograde cholangiopancreatography (ERCP) represents the most powerful and widely employed platform for pancreaticobiliary interventions. Endoscopic retrograde cholangiopancreatography allows diagnosis and treatment of a broad spectrum of diseases of the pancreaticobiliary tree that are both benign and malignant in nature. Endoscopic retrograde cholangiopancreatography continues to evolve rapidly, and non-gastroenterologists need to understand the indications, contraindications, limitations, and role of ERCP to effectively manage and coordinate the care of patients with known or suspected pancreaticobiliary disease. This article will review the role of ERCP in detail to further an understanding of the procedure as a whole and to assess when referral of a patient for an ERCP or other related test is indicated.

Nurse-administered propofol sedation is safe for patients with obstructive sleep apnea undergoing routine endoscopy: a pilot study.

BACKGROUND: Nurse-administered propofol sedation (NAPS) is now in widespread use. The safety profile of NAPS for routine endoscopic procedures in patients with obstructive sleep apnea (OSA) is unknown. AIMS: To compare outcomes of patients with and without OSA undergoing routine endoscopic procedures with NAPS and standard conscious sedation (CS) with benzodiazepines and narcotics. METHODS: Retrospective cohort study. RESULTS: A total of 215 patients were placed in one of four groups: OSA patients undergoing endoscopy with NAPS, OSA patients undergoing endoscopy with standard CS, non-OSA patients undergoing endoscopy with NAPS, and non-OSA patients undergoing endoscopy with standard CS. Procedures were generally accomplished faster with NAPS. There was no statistically significant difference in complication rates or overall outcomes in patients with OSA when compared to non-OSA patients when either NAPS or CS was utilized. CONCLUSIONS: Routine endoscopic procedures using NAPS are safe in patients with documented OSA, with complication rates comparable to when using CS. NAPS helped to decrease procedure times in general.

Endoscopic biliary sphincterotomy is not required for transpapillary SEMS placement for biliary obstruction.

BACKGROUND: Endoscopic retrograde cholangiopancreatography with biliary self-expanding metal stent placement is the preferred method of providing biliary drainage for pancreaticobiliary malignancies. Some endoscopists routinely perform biliary sphincterotomy to facilitate biliary stent placement and potentially minimize pancreatitis with transpapillary self-expanding metal stent placement. AIMS: Our hypothesis was that biliary sphincterotomy has no effect on the success rate of transpapillary self-expanding metal stent placement and increases procedure-related complications. METHODS: In a retrospective analysis, outcomes of two groups were compared: (1) self-expanding metal stent placement without biliary sphincterotomy, (2) self-expanding metal stent placement with biliary sphincterotomy during the same procedure. Complications and stent patency rates were evaluated. RESULTS: There were 104 subjects included in the study. Post-sphincterotomy bleeding (p = 0.001) was associated with biliary sphincterotomy performed immediately prior to self-expanding metal stent placement. Importantly, self-expanding metal stent placement without biliary sphincterotomy was always technically successful and self-expanding metal stent placement without biliary sphincterotomy was not associated with pancreatitis. CONCLUSIONS: Patients who undergo biliary sphincterotomy during transpapillary self-expanding metal stent placement experience more immediate complications than those who do not. Biliary sphincterotomy was not associated with longer stent patency. Self-expanding metal stent placement without a biliary sphincterotomy was not associated with pancreatitis regardless of the type of self-expanding metal stent used (covered or uncovered). Of the patients without a biliary sphincterotomy, 100% had successful stent placement, further arguing against its use in this setting.

Osteoclastic and pleomorphic giant cell tumors of the pancreas: A review of clinical, endoscopic, and pathologic features.

Giant cell tumors of the pancreas come in three varieties-osteoclastic, pleomorphic, and mixed histology. These tumors have distinctive endoscopic, clinical, and cytological features. Giant cell tumors have a controversial histogenesis, with some authors favoring an epithelial origin and others favoring a mesenchymal origin. The true origin of these lesions remains unclear at this time. These are also very rare tumors but proper identification and differentiation from more common pancreatic adenocarcinoma is important. The risk factors of these tumors and the prognosis may be different from those associated with standard pancreatic adenocarcinoma. Recognition of these differences can significantly affect patient care. These lesions have a unique appearance when imaged with endoscopic ultrasound (EUS), and these lesions can be diagnosed via EUS guided Fine Needle Aspiration (FNA). This manuscript will review the endoscopic, clinical, and pathologic features of these tumors.

What drives US gastroenterology fellows to pursue academic vs. non-academic careers?: Results of a national survey.

OBJECTIVES: We conducted a nationwide survey of US gastroenterology fellows to identify key demographic and job-related factors relevant to the decision between an academic and a non-academic career. METHODS: A survey was e-mailed to all US GI fellowship program directors and distributed at fellows' endoscopy courses. Data were evaluated via univariate and multivariate analysis. RESULTS: One hundred eighty-four fellows completed surveys. Univariate analysis identified one factor that predisposed fellows to pursue non-academic practice: the perception that a non-academic salary would meet their financial needs. Four factors were identified that predisposed fellows to pursue academic practice: age>35 years, prior attainment of a master's or a PhD degree, and advanced fellowship. All factors were significant on multivariate analysis. If salaries were equal, 60% of respondents would choose academic over non-academic practice. Fellows selecting academic practice were motivated to publish and conduct research. Level of debt and a positive relationship with a mentor were not significant factors. CONCLUSIONS: Fellows desiring more money strongly favor non-academic practice. Fellows choosing academic practice tend to be older, plan to pursue advanced training, desire fewer work hours per week, and have a higher rate of prior graduate study. If salaries were equal in academic medicine and non-academic practice, the majority of fellows would choose academic medicine.

Comparison of esomeprazole to aerosolized, swallowed fluticasone for eosinophilic esophagitis.

BACKGROUND: Both gastroesophageal reflux disease and allergy/atopy have been implicated in the pathogenesis of eosinophilic esophagitis (EoE). There are no prospective studies comparing treatment of EoE with acid suppression versus topical corticosteroids. OBJECTIVE: To determine the outcome of adult eosinophilic esophagitis patients treated with esomeprazole versus topical fluticasone. DESIGN: Prospective randomized controlled trial. SETTING: Academic medical center. PARTICIPANTS: Adults (18-80) diagnosed with EoE by symptoms of dysphagia and esophageal biopsies with >or=15 eosinophils/hpf. INTERVENTIONS: Subjects were randomized to esomeprazole (40 mg by mouth every morning) or aerosolized, swallowed fluticasone (440 mcg by mouth twice a day) for 8 weeks. MAIN OUTCOME MEASUREMENTS: Improvement in dysphagia (8-point scale), esophageal eosinophil infiltration before and after treatment, prevalence of GERD measured by validated questionnaire and baseline pH study. RESULTS: About 56% (14/25) had acid reflux by pH study. There was no difference between treatment groups in improvement in dysphagia scores [3/12 (25%) of the esomeprazole group versus 6/12 (50%) in the fluticasone group, P = 0.40]. Eosinophil infiltration decreased with treatment in both groups, and there was no difference in the amount of decrease between groups (P = 0.70). LIMITATIONS: Small sample size, unexpectedly high drop-out rate. CONCLUSIONS: Gastroesophageal reflux disease is common in adult eosinophilic esophagitis patients. Dysphagia improves and esophageal eosinophilic infiltration decreases with either treatment. There was no difference in degree of improvement in dysphagia or eosinophil infiltration in patients treated with either topical fluticasone or oral esomeprazole. GERD may be important in the pathogenesis of adult EoE.
