RESUMO
BACKGROUND: Food-specific immunoglobulin G4 (FS-IgG4) is associated with eosinophilic esophagitis (EoE); however, it is not clear whether production is limited to the esophagus. AIMS: To assess FS-IgG4 levels in the upper gastrointestinal tract and plasma and compare these with endoscopic disease severity, tissue eosinophil counts, and patient-reported symptoms. METHODS: We examined prospectively banked plasma, throat swabs, and upper gastrointestinal biopsies (esophagus, gastric antrum, and duodenum) from control (n = 15), active EoE (n = 24), and inactive EoE (n = 8) subjects undergoing upper endoscopy. Patient-reported symptoms were assessed using the EoE symptom activity index (EEsAI). Endoscopic findings were evaluated using the EoE endoscopic reference score (EREFS). Peak eosinophils per high-power field (eos/hpf) were assessed from esophageal biopsies. Biopsy homogenates and throat swabs were normalized for protein content and assessed for FS-IgG4 to milk, wheat, and egg. RESULTS: Median FS-IgG4 for milk and wheat was significantly increased in the plasma, throat swabs, esophagus, stomach, and duodenum of active EoE subjects compared to controls. No significant differences for milk- or wheat-IgG4 were observed between active and inactive EoE subjects. Among the gastrointestinal sites sampled, FS-IgG4 levels were highest in the esophagus. Esophageal FS-IgG4 for all foods correlated significantly across all sites sampled (r ≥ 0.59, p < 0.05). Among subjects with EoE, esophageal FS-IgG4 correlated significantly with peak eos/hpf (milk and wheat) and total EREFS (milk). EEsAI scores and esophageal FS-IgG4 levels did not correlate. CONCLUSIONS: Milk and wheat FS-IgG4 levels are elevated in plasma and throughout the upper gastrointestinal tract in EoE subjects and correlate with endoscopic findings and esophageal eosinophilia.

BACKGROUND & AIMS: Substantial heterogeneity in terminology used for eosinophilic gastrointestinal diseases (EGIDs), particularly the catchall term "eosinophilic gastroenteritis," limits clinical and research advances. We aimed to achieve an international consensus for standardized EGID nomenclature. METHODS: This consensus process utilized Delphi methodology. An initial naming framework was proposed and refined in iterative fashion, then assessed in a first round of Delphi voting. Results were discussed in 2 consensus meetings, and the framework was updated and reassessed in a second Delphi vote, with a 70% threshold set for agreement. RESULTS: Of 91 experts participating, 85 (93%) completed the first and 82 (90%) completed the second Delphi surveys. Consensus was reached on all but 2 statements. "EGID" was the preferred umbrella term for disorders of gastrointestinal (GI) tract eosinophilic inflammation in the absence of secondary causes (100% agreement). Involved GI tract segments will be named specifically and use an "Eo" abbreviation convention: eosinophilic gastritis (now abbreviated EoG), eosinophilic enteritis (EoN), and eosinophilic colitis (EoC). The term "eosinophilic gastroenteritis" is no longer preferred as the overall name (96% agreement). When >2 GI tract areas are involved, the name should reflect all of the involved areas. CONCLUSIONS: This international process resulted in consensus for updated EGID nomenclature for both clinical and research use. EGID will be the umbrella term, rather than "eosinophilic gastroenteritis," and specific naming conventions by location of GI tract involvement are recommended. As more data are developed, this framework can be updated to reflect best practices and the underlying science.

BACKGROUND: Diagnosis of eosinophilic esophagitis (EoE) requires manual quantification of tissue eosinophils. Eosinophil peroxidase (EPX) is an eosinophil-specific, cytoplasmic granule protein released during degranulation. AIMS: The objective of this study was to evaluate image analysis of EPX immunohistochemistry as an automated method for histologic diagnosis of EoE. METHODS: We performed a secondary analysis of prospectively collected esophageal biopsies obtained from adult subjects with EoE and controls. Tissue sections were stained with hematoxylin and eosin (H&E) and evaluated for peak eosinophils per high power field (eos/hpf). The same slides were de-stained and re-stained to detect EPX for direct comparison. Slides were digitized, and EPX staining area/mm2 was quantified using image analysis. Paired samples were compared for changes in EPX staining in treatment responders and non-responders. RESULTS: Thirty-eight EoE cases and 49 controls were analyzed. Among EoE subjects, matched post-treatment biopsies were available for 21 responders and 10 non-responders. Baseline EPX/mm2 was significantly increased in EoE subjects and decreased in treatment responders. EPX quantification correlated strongly with eos/hpf (r = 0.84, p < 0.0001) and identified EoE subjects with high diagnostic accuracy (AUC 0.95, p < 0.0001). The optimal diagnostic EPX-positive pixel/area threshold was 17,379 EPX/mm2. Several controls (5/49) with < 15 eos/hpf on H&E staining exceeded this cutoff. CONCLUSIONS: EPX/mm2 correlates strongly with eos/hpf, accurately identifies subjects with EoE, and decreases in treatment responders. Automated quantification of intact eosinophils and their degranulation products may enhance pathologic assessment. Future studies are needed to correlate EPX/mm2 with symptoms, endoscopic findings, and esophageal distensibility.

INTRODUCTION: Normal response to multiple rapid swallows (MRS) during high-resolution esophageal manometry is deglutitive inhibition; opioids may interfere with this. The aim of this study was to evaluate the response to MRS in patients on opioids, not on opioids, and healthy controls. METHODS: Response to MRS was evaluated for complete vs impaired inhibition in 72 chronic opioid users, 100 patients not on opioids, and 24 healthy controls. RESULTS: Impaired deglutitive inhibition was significantly more frequent in chronic opioid users compared with patients not on opioids and healthy controls (54% vs 14% vs 0%; P < 0.0001). DISCUSSION: Impaired deglutitive inhibition during MRS is frequent in opioid users, supporting that opioids interfere with esophageal inhibitory signals.

BACKGROUND: Inpatient status has been shown to be a predictor of poor bowel preparation for colonoscopy; however, the optimal bowel preparation regimen for hospitalized patients is unknown. Our aim was to compare the efficacy of bowel preparation volume size in hospitalized patients undergoing inpatient colonoscopy. METHODS: This prospective, single blinded (endoscopist), randomized controlled trial was conducted as a pilot study at a tertiary referral medical center. Hospitalized patients undergoing inpatient colonoscopy were assigned randomly to receive a high, medium, or low-volume preparation. Data collection included colon preparation quality, based on the Boston Bowel Preparation Scale, and a questionnaire given to all subjects evaluating the ability to completely finish bowel preparation and adverse effects (unpleasant taste, nausea, and vomiting). RESULTS: Twenty-five colonoscopies were performed in 25 subjects. Patients who received low-volume preparation averaged a higher mean total BBPS (7.4, SD 1.62), in comparison to patients who received high-volume (7.0, SD 1.41) and medium-volume prep (6.9, SD 1.55), P = 0.77. When evaluating taste a higher score meant worse taste. The low-volume group scored unpleasant taste as 0.6 (0.74), while the high-volume group gave unpleasant taste a score of 2.2 (0.97) and the medium-volume group gave a score of 2.1 (1.36), P < 0.01. CONCLUSION: In this pilot study we found that low-volume colon preparation may be preferred in the inpatient setting due its better rate of tolerability and comparable bowel cleanliness when compared to larger volume preparation, although we cannot overreach any definitive conclusion. Further more robust studies are required to confirm these findings. TRIAL REGISTRATION: The Affect of Low-Volume Bowel Preparation for Hospitalized Patients Colonoscopies. TRIAL REGISTRATION: NCT01978509 (terminated). Retrospectively registered on November 07, 2013.

Distal esophageal spasm (DES) is a motility disorder characterized by premature contraction of the esophageal body during single swallows. It is thought to be due to impairment of esophageal inhibitory pathways, but studies to support this are limited. The normal response to multiple rapid swallows (MRS) is deglutitive inhibition of the esophageal body during the MRS sequence. Our aim was to compare the response to MRS in DES patients and healthy control subjects. Response to MRS during HRM was evaluated in 19 DES patients (8 with and 11 without concomitant esophagogastric junction outflow obstruction [EGJOO]) and 24 asymptomatic healthy controls. Patients with prior gastroesophageal surgery, peroral endoscopic myotomy, pneumatic dilation, esophageal botulinum toxin injection within 6 months of HRM, opioid medication use, and esophageal stricture were excluded. Response to MRS was evaluated for complete versus impaired inhibition (esophageal body contractility with distal contractile integral [DCI] > 100 mmHg-sec-cm during MRS), presence of post-MRS contraction augmentation (DCI post MRS greater than single swallow mean DCI), and integrated relaxation pressure (IRP). Impaired deglutitive inhibition during MRS was significantly more frequent in DES compared to controls (89% vs. 0%, P < 0.001), and frequency was similar for DES with versus without concomitant EGJOO (100% vs. 82%, P = 0.48). The proportion of subjects with augmentation post MRS was similar for both groups (37% vs. 38%, P = 1.00), but mean DCI post MRS was higher in DES than controls (3360.0 vs. 1238.9, P = 0.009). IRP was lower during MRS compared to single swallows in all patients, and IRP during MRS was normal in 5 of 8 patients with DES and EGJOO. Our study suggests that impaired deglutitive inhibition during MRS is present in the majority of patients with DES regardless of whether they have concomitant EGJOO, and future studies should explore the usefulness of incorporating response to MRS in the diagnosis of DES.

OBJECTIVE: Data regarding opioid effects on esophageal function are limited. We previously demonstrated an association between chronic opioid use and esophageal motor dysfunction characterized by esophagogastric junction outflow obstruction, distal esophageal spasm, achalasia type III, and possibly Jackhammer esophagus. Our aim was to characterize the influence of different opioids and doses on esophageal dysfunction. METHODS: Retrospective review of 225 patients prescribed oxycodone, hydrocodone, or tramadol for >3 months, who completed high-resolution manometry from 2012 to 2017. Demographic and manometric data were extracted from a prospectively maintained motility database. Frequency of opioid-induced esophageal dysfunction (OIED, defined as distal esophageal spasm, esophagogastric junction outflow obstruction, achalasia type III, or Jackhammer esophagus on high-resolution manometry, was compared among different opioids. The total 24-hour opioid doses for oxycodone, hydrocodone, and tramadol were converted to a morphine equivalent for dose effect analysis. RESULTS: OIED was present in 24% (55 of 225) of opioid users. OIED was significantly more prevalent with oxycodone or hydrocodone use compared with tramadol (31% vs 28% vs 12%, P = 0.0162), and for oxycodone alone vs oxycodone with acetaminophen (43% vs 21%, P = 0.0482). There was no difference in OIED for patients taking hydrocodone alone vs hydrocodone with acetaminophen. Patients with OIED were taking a higher median 24-hour opioid dose than those without OIED (45 vs 30 mg, P = 0.058). DISCUSSION: OIED is more prevalent in patients taking oxycodone or hydrocodone compared with tramadol. There is greater likelihood of OIED developing with higher doses. Reducing the opioid dose or changing to tramadol may reduce OIED in opioid users.

Malignancy represents substantial morbidity and mortality in patients with primary sclerosing cholangitis (PSC). This subset of patients has been proven to be at increased risk for developing cholangiocarcinoma, gallbladder carcinoma and colorectal cancer in those with overlapping inflammatory bowel disease. Herein, we review the prevalence of these malignancies and recommend screening tools and current knowledge to reduce the disease burden in this population. Cholangiocarcinoma is the most dominant malignancy affecting PSC patients, with a lifetime risk ranging from 5% to 20%. We advocate for serial US or MRI/MRCP and CA 19-9 to screen for cholangiocarcinoma. Gallbladder cancer has a lifetime risk around 2% in this population and we agree with annual imaging for lesions as recommended by national guidelines. Patients with PSC and concomitant IBD are at increased risk of colorectal carcinoma from time of diagnosis and therefore should likely undergo annual surveillance. The low rates of hepatocellular cancer and pancreatic cancer indicate surveillance for these malignancies is less advantageous.

PURPOSE OF REVIEW: To quantify direct oral anticoagulants (DOACs) related gastrointestinal bleeding (GIB), characterize patients at greatest risk and provide a pragmatic approach for the management of these drugs. This review will also summarize risk-management strategies and highlight evolving areas of clinical knowledge. RECENT FINDINGS: DOACs permit anticoagulation with predictable dosing without the need for routine serum monitoring. Since their availability on the market, they have quickly emerged as a popular alternative for patients requiring short-term and lifelong anticoagulation. However, they are associated with an increased risk of GIB when compared with warfarin; thus, gastroenterologists must be prepared to manage DOAC-related GIB and prevent drug-related complications. This review will focus on acute and elective periendoscopic DOAC management, high-risk clinical groups for DOAC-related GIB, quantification of DOAC levels, use of reversal agents and minimization of thromboembolic risk associated with temporary interruption. SUMMARY: This review will highlight pragmatic strategies for the treatment of DOAC-related bleeding and the prevention of postendoscopic DOAC bleeding. It will address new and evolving areas of periendoscopic management and identify knowledge gaps requiring further research to inform clinical practice.

Endoscopic retrograde cholangiopancreatography (ERCP) in patients with surgically altered upper gastrointestinal anatomy, such as Roux-en-Y gastric bypass (RYGB), can be more challenging compared to those with a normal anatomy. Detailed assessment of cross-sectional imaging features by the radiologist, especially the pancreaticobiliary anatomy, strictures, and stones, is very helpful to the endoscopist in planning the procedure. In addition, any information on enteral anastomoses (for e.g., gastrojejunal strictures and afferent limb obstruction) is also very useful. The endoscopist should review the operative note to understand the exact anatomy prior to procedure. RYGB, which is performed for medically complicated obesity, is the most commonly encountered altered anatomy ERCP procedure. Other situations include patients who have had a pancreaticoduodenectomy or a hepaticojejunostomy. Balloon-assisted deep enteroscopy (single and double-balloon enteroscopy) or rotational endoscopy is often used to traverse the length of the intestine to reach the papilla. In addition, ERCP in these patients is further challenging due to the oblique orientation of the papilla relative to the forward viewing endoscope and the limited enteroscopy-length therapeutic accessories that are currently available. Overall, reported therapeutic success is approximately 70-75% with a complication rate of 3-4%. Alternative approaches include percutaneous transhepatic cholangiography, laparoscopy-assisted ERCP, or surgery. Given the complexity, ERCP in patients with surgically altered anatomy should be performed in close collaboration with body imagers, interventional radiology, and surgical services.

OBJECTIVES: Although guidelines recommend hepatitis B virus (HBV) immunization for adults with diabetes mellitus (DM), vaccination rates remain low. Our aim was to evaluate knowledge and practice regarding HBV and to assess the effectiveness of a multifaceted educational program. METHODS: Primary care residents (n = 244) at three academic institutions were surveyed about various aspects of HBV. Residents at one training program were then randomly assigned to an educational intervention (E) (n = 20) and control group (C) (n = 19). The E group received a focused didactic lecture and periodic e-mail reminders with immediate feedback. We compared knowledge scores before and after the intervention. Chart audits were conducted to evaluate the residents' behavior. RESULTS: A total of 103 (42%) residents responded to the survey. The survey indicated that residents lacked the necessary knowledge and risk assessment skills concerning HBV in patients with DM. In the controlled trial of the E intervention, both groups had similar baseline knowledge scores. The E group had a significant increase in the immediate postintervention knowledge scores from a mean of 29% at baseline to 70% (P < 0.001) that was sustained 6 months postintervention (65%; P < 0.001). In the C group, 6-month postintervention scores were not different from baseline (38% vs 29%). No significant differences were observed in documentation skills. CONCLUSIONS: A combined educational program was effective in enhancing knowledge about HBV and vaccination in DM but had limited influence on physicians' practice. Further study incorporating system changes along with educational initiatives is required to improve clinical practice.

CONTEXT: Segmental arterial mediolysis is an uncommon, non-atherosclerotic, non-inflammatory arteriopathy that involves areas of dissecting aneurysms and strictures that are caused by outer media lysis of the arterial wall from areas of medial necrosis of uncertain pathogenesis. It has a predilection for splanchnic arteries and often presents as abdominal pain or hemorrhage in late middle-aged and elderly patients. Diagnosis can be established by computed tomography angiography, magnetic resonance angiography, or angiogram by visualizing typical abnormalities, in addition to excluding other vasculitides. Histological confirmation is the gold standard but is not easily accessible and, as such, is not frequently performed. CASE REPORT: Here we present an updated review of the literature and a case of segmental arterial mediolysis that presented with spontaneous intra-abdominal bleeding near the pancreas that was originally misdiagnosed as hemorrhagic pancreatitis. CONCLUSION: Diagnosis is important because immunosuppressants for vasculitis can worsen the arteriopathy. Segmental arterial mediolysis can be self-limiting without treatment or may require urgent surgical or endovascular therapy for bleeding and carries a 50% mortality rate. Therefore, it should be included in the differential of causes of abdominal pain as well as in cases of unexplained abdominal hemorrhage.

INTRODUCTION: We aimed to assess the diagnostic utility of eosinophil peroxidase (EPX) staining on Cytosponge (CS) samples in eosinophilic esophagitis (EoE). METHODS: Esophageal biopsy (BX) samples from adult subjects with EoE were assessed using peak eosinophils per high-power field (eos/hpf), EPX, and the EoE histologic scoring system. EPX staining and eos/hpf were compared (BX vs CS). RESULTS: CS EPX positivity correlated with eos/hpf (CS [ r = 0.82, P < 0.0001]; BX [ r = 0.65, P < 0.0001]) and EoE histologic scoring system (grade [ r = 0.62, P < 0.00001]; stage [ r = 0.61, P < 0.0001]). CS EPX identified subjects with active EoE (area under the curve = 0.86, P < 0.0001). DISCUSSION: The correlation of CS EPX with eosinophilic inflammation and histologic disease severity supports its diagnostic utility in EoE.

OBJECTIVE: We aim to review the imaging features of eosinophilic esophagitis on fluoroscopy and present how they can correlate with endoscopic and pathologic findings. RESULTS: Eosinophilic esophagitis is a chronic immune-mediated disease that results in esophageal dysfunction. Upper esophagogastroduodenoscopy is high yield and required for biopsies to demonstrate the hallmark histologic findings of eosinophil-predominant inflammation. While esophagogastroduodenoscopy is currently mandatory for diagnosis, imaging findings can provide valuable information regarding the structural and functional properties of the esophagus. In addition, fluoroscopic studies may be very helpful in the setting of subtle findings and to evaluate fibrotic remodeling changes. CONCLUSION: Radiologic examinations are a valuable tool in the assessment of eosinophilic esophagitis and can highlight changes of fibrostenotic disease, as overall narrowing can be more conspicuous fluoroscopically than endoscopically. As the disease increases in prevalence, it is critical that physicians recognize this condition and facilitate diagnosis and treatment.

Ingestion of a foreign body is a common occurrence. Flexible endoscopy is most commonly used for treatment, but certain large foreign bodies are more easily retrieved with rigid endoscopy. We present a technically challenging case of intentional ingestion of a large stone that required retrieval from the upper thoracic esophagus using rigid endoscopy. This case highlights the importance of alternative methods to manage large foreign bodies and of collaboration of medical subspecialties.
RESUMO
Eosinophilic esophagitis (EoE) is a clinicopathologic disease characterized by symptoms of esophageal dysfunction and esophageal eosinophilia. In the last decade, there has been a dramatic increase in its prevalence for reasons that are not completely understood. The underlying pathophysiology involves an antigen-mediated TH 2 immune response that draws eosinophils to the esophagus, causing mucosal inflammation, esophageal remodeling, and fibrosis. This ultimately leads to esophageal dysfunction that most commonly manifests as dysphagia. In this review, we will discuss updates on key questions regarding the diagnosis and treatment of EoE.
