RESUMO
BACKGROUND AND AIMS: The American Society for Gastrointestinal Endoscopy (ASGE) advanced endoscopy fellowship (AEF) match offers a structured application process for AEF training in the United States. Our aim was to describe recent trends in AEF match, trainee experience, and postfellowship employment. METHODS: ASGE AEF match data from 2012 to 2020 were reviewed. Online surveys were sent to advanced endoscopy trainees in 2019 and 2020 to explore their perceptions about AEF training and postfellowship jobs. RESULTS: Data for 2020 showed 19% of matched applicants were women, 55% foreign medical graduates, and 17.5% U.S. visa holders. The number of AEF match applicants increased by 15.6% (90 in 2012 to 104 in 2020) and number of AEF programs increased by 23.5% (51 in 2012 to 63 in 2020). The average applicant match rate was 57% (range, 52.8%-60.6%) and position match rate 87.9% (range, 79.1%-94.6%). Ninety-one percent of trainees (n = 58) rated the quality of their training as very good/excellent; 75% of trainees participated in >300 ERCPs and 64.1% in >300 EUS cases. Seventy percent of trainees reported that advanced endoscopic procedures comprised ≤50% of their procedure volume in their first job, and 71.9% believed it was not easy to find a job after fellowship; however, 97% believed they would make the same decision to pursue AEF training again. CONCLUSIONS: There has been a steady increase in the number of advanced endoscopy applicants and training positions over recent years. Most graduating fellows reported 50% or less of their upcoming clinical practice would involve advanced endoscopic procedures. Future studies are needed to further clarify employment opportunities and personnel needs for advanced endoscopists.

BACKGROUND: Patients with familial adenomatous polyposis (FAP) frequently undergo colectomy to reduce the 70 to 90% lifetime risk of colorectal cancer. After risk-reducing colectomy, duodenal cancer and complications from duodenal surgeries are the main cause of morbidity. Our objective was to prospectively describe the duodenal and gastric polyp phenotype in a cohort of 150 FAP patients undergoing pre-screening for a chemoprevention trial and analyze variables that may affect recommendations for surveillance. METHODS: Individuals with a diagnosis of FAP underwent prospective esophagogastroduodenoscopy using a uniform system of mapping of size and number of duodenal polyps for a 10 cm segment. Gastric polyps were recorded as the total number. RESULTS: The distribution of the count and sum diameter of duodenal polyps were statistically different in two genotype groups, those with APC mutations associated with classic FAP had a greater count (median 17) and sum diameter of polyps (median 32 mm) than those with APC mutations associated with attenuated FAP (median count 4 and median sum diameter of 7 mm) (p < 0.0001). The number of gastric polyps did not differ based on genotype (p = 0.67) but advancing age correlated with severity of gastric polyposis (p = 0.019). Spigelman (modified) staging of II or greater was found in 88% of classic FAP patients and 48% attenuated FAP patients. Examples of severe and mild upper GI phenotype are observed in patients with identical APC mutations, showing that the APC mutation location is not absolutely predictive of an upper GI phenotype. CONCLUSIONS: Most FAP patients have duodenal and gastric polyps which become more prevalent and advanced with age. Standard upper endoscopic surveillance is recommended based on personal history independent of APC mutation location. TRIAL REGISTRATION: NCT 01187901 registered August 24, 2010, prospective to enrollment.

BACKGROUND AND OBJECTIVES: Biliary tract cancers (BTC) including, cholangiocarcinoma (CC) and gallbladder cancer (GBC), are rare and highly fatal malignancies. The etiology and inherited susceptibility of both malignancies are poorly understood. We quantified the risk of BTC in first-degree (FDR), second-degree (SDR), and first cousin (FC) relatives of individuals with BTC, stratified by tumor subsite. METHODS: BTC diagnosed between 1980 and 2011 were identified from the Utah Cancer Registry and linked to pedigrees from the Utah Population Database. Age- and gender-matched BTC-free controls were selected to form the comparison group for determining BTC risk in relatives using Cox regression analysis. RESULTS: Of the 1302 index patients diagnosed with BTC, 550 (42.2 %) were located in the gallbladder and 752 (57.8 %) were cholangiocarcinomas. There was no elevated risk of BTC (all subsites combined) in FDRs (HR 0.94, 95 % CI 0.29-3.0), SDRs (HR 0.25, 95 % CI 0.06-1.03), and FCs (HR 0.96, 95 % CI 0.61-1.51) of BTC cases compared to cancer-free controls. Similarly, no increased familial risk of GBC or CC was found in relatives of BTC patients stratified by tumor subsite compared to relatives of controls. CONCLUSIONS: Relatives of BTC patients are not at an increased risk of GBC or CC in a statewide population. This suggests that biliary tract cancer risk is not associated with a familial predisposition and may be mitigated more strongly by environmental modifiers.

IMPORTANCE: Patients with familial adenomatous polyposis (FAP) are at markedly increased risk for duodenal polyps and cancer. Surgical and endoscopic management of duodenal neoplasia is difficult and chemoprevention has not been successful. OBJECTIVE: To evaluate the effect of a combination of sulindac and erlotinib on duodenal adenoma regression in patients with FAP. DESIGN, SETTING, AND PARTICIPANTS: Double-blind, randomized, placebo-controlled trial, enrolling 92 participants with FAP, conducted from July 2010 through June 2014 at Huntsman Cancer Institute in Salt Lake City, Utah. INTERVENTIONS: Participants with FAP were randomized to sulindac (150 mg) twice daily and erlotinib (75 mg) daily (n = 46) vs placebo (n = 46) for 6 months. MAIN OUTCOMES AND MEASURES: The total number and diameter of polyps in the proximal duodenum were mapped at baseline and 6 months. The primary outcome was change in total polyp burden at 6 months. Polyp burden was calculated as the sum of the diameters of polyps. The secondary outcomes were change in total duodenal polyp count, change in duodenal polyp burden or count stratified by genotype and initial polyp burden, and percentage of change from baseline in duodenal polyp burden. RESULTS: Ninety-two participants (mean age, 41 years [range, 24-55]; women, 56 [61%]) were randomized when the trial was stopped by the external data and safety monitoring board because the second preplanned interim analysis met the prespecified stopping rule for superiority. Grade 1 and 2 adverse events were more common in the sulindac-erlotinib group, with an acne-like rash observed in 87% of participants receiving treatment and 20% of participants receiving placebo (P < .001). Only 2 participants experienced grade 3 adverse events. [table: see text]. CONCLUSIONS AND RELEVANCE: Among participants with FAP, the use of sulindac and erlotinib compared with placebo resulted in a lower duodenal polyp burden after 6 months. Adverse events may limit the use of these medications at the doses used in this study. Further research is necessary to evaluate these preliminary findings in a larger study population with longer follow-up to determine whether the observed effects will result in improved clinical outcomes.

OBJECTIVES: Elemental diets have not been studied in adults with eosinophilic esophagitis (EoE). The goal of this trial was to assess the efficacy of an elemental diet in adults with EoE. METHODS: A total of 18 adults with EoE were given an elemental diet for 4 weeks, or just 2 weeks if their response was complete. Symptoms and histologic findings, based on biweekly biopsies, were monitored. Six subjects were rebiopsied 2-7 days after resuming a normal diet. RESULTS: After therapy, esophageal tissue eosinophil content decreased from 54 to 10 per maximal high power field (P=0.0006). There was complete or nearly complete response (≤10 eosinophils) in 72% of subjects. Mast cell content, parabasal layer thickness, and endoscopic furrows and exudates also significantly decreased. Of the 29 qualified subjects, 11 (38%) failed to adhere to the diet. Several subjects had significant weight loss. Symptoms and endoscopic fixed strictures did not improve. After the subjects resumed a normal diet, the eosinophil content increased substantially in 3-7 days. CONCLUSIONS: While symptoms did not improve and dietary compliance was problematic, there was substantial histologic improvement after 4 weeks on the elemental diet. EoE in adults is substantially triggered by foods.

Synthetic lifting media, ORISE™ gel and Eleview®, are increasingly used in gastrointestinal endoscopy, but neither comparative features nor pitfalls are well-established. Media histopathology, morphologic mimics, and complications are described, along with helpful stains and endoscopist media preference. A 3-year retrospective search was performed. A total of 123 cases (108 endoscopies and 15 subsequent surgeries) were identified. ORISE gel was used in 86 (79.6%), Eleview in 20 (13.9%), and others in 7 (6.5%). ORISE gel was histologically identified in 58.1% (n = 50) of endoscopic specimens and all 15 resections. Eleview media were not detected histologically. ORISE gel mimicked mucin in hematoxylin and eosin-stained biopsies, concerning for adenocarcinoma misdiagnosis and/or upstaging, but did not stain for mucin. Acid-fast bacterial staining highlights ORISE gel for specific and definitive identification. In resections, ORISE evolves into an amorphous eosinophilic material, often with exuberant giant cell reaction and transmural bowel penetration. Polyp formation leads to polypectomy in one patient, and operative lesions concerning for adenocarcinoma resulted in frozen sections in two patients. ORISE gel mimics mucin, malignant masses, amyloid, pulse granulomata, elastofibromas, and infectious granulomata. No significant endoscopist media preference was identified. Recognition of ORISE gel in tissues eliminates multiple pitfalls. Eleview was not detectable, yielded none of the pitfalls seen with ORISE gel, and, on our survey, has equivalent endoscopist acceptance. In this largest published series to date, Eleview is clearly preferable to ORISE gel.

To identify gene expression biomarkers and pathways targeted by sulindac and erlotinib given in a chemoprevention trial with a significant decrease in duodenal polyp burden at 6 months (P < 0.001) in familial adenomatous polyposis (FAP) patients, we biopsied normal and polyp duodenal tissues from patients on drug versus placebo and analyzed the RNA expression. RNA sequencing was performed on biopsies from the duodenum of FAP patients obtained at baseline and 6-month endpoint endoscopy. Ten FAP patients on placebo and 10 on sulindac and erlotinib were selected for analysis. Purity of biopsied polyp tissue was calculated from RNA expression data. RNAs differentially expressed between endpoint polyp and paired baseline normal were determined for each group and mapped to biological pathways. Key genes in candidate pathways were further validated by quantitative RT-PCR. RNA expression analyses of endpoint polyp compared with paired baseline normal for patients on placebo and drug show that pathways activated in polyp growth and proliferation are blocked by this drug combination. Directly comparing polyp gene expression between patients on drug and placebo also identified innate immune response genes (IL12 and IFNγ) preferentially expressed in patients on drug. Gene expression analyses from tissue obtained at endpoint of the trial demonstrated inhibition of the cancer pathways COX2/PGE2, EGFR, and WNT. These findings provide molecular evidence that the drug combination of sulindac and erlotinib reached the intended tissue and was on target for the predicted pathways. Furthermore, activation of innate immune pathways from patients on drug may have contributed to polyp regression. Cancer Prev Res; 11(1); 4-15. ©2017 AACRSee related editorial by Shureiqi, p. 1.

Eosinophilic Esophagitis (EE) is an emerging cause of esophageal food impaction (EFI) not accounted for in previous studies. We sought to determine the causes of EFI in a recent cohort with recognition of EE. A retrospective chart review of all patients with EFI during the past 5 years was performed. Etiology was determined by endoscopy report, pathology results, and follow-up studies. A total of 85 EFIs occurred, in 79 patients (55 men, 30 women, age 18-100). The most common etiologies of EFI were Schatzki's ring (n = 18), peptic stricture (n = 18), EE (n = 9), esophagitis (n = 9), and no underlying diagnosis (n = 20). EE was significantly more frequent in men (P < .025) and those <50 years old (P < .025). There was a significant difference in the age at which men (median age = 44) and women (median age = 71) present with EFI (P < .001). The etiology of EFI differs significantly by age and gender. This information may be useful in evaluation and management of EFI.

PURPOSE OF REVIEW: Critical to realizing increasing benefits of enteral nutrition are techniques for feeding tube placement. Feeding tubes can be placed by bedside, endoscopic, fluoroscopic, and surgical methods. This review encompasses noteworthy studies on endoscopic approaches to enteral feeding published from January 2005 to the present. RECENT FINDINGS: Studies involving placement of nasoenteric feeding tubes include description of new methods for endoscopic nasoenteric feeding tube placement using a push technique with a stiffened tube, a modification of the 'drag and pull' method using a distal suture tie, and placement using an ultrathin transnasal endoscopic technique compared with fluoroscopic placement. Recent studies involving percutaneous endoscopic gastrostomy tube placement have demonstrated equivalent outcomes of endoscopic and fluoroscopic approaches, description of unsedated placement using transnasal technique, and risk of percutaneous endoscopic gastrostomy site metastasis in head and neck cancer patients. Studies on percutaneous jejunal feeding tubes demonstrate: high complication rate and short functional duration of percutaneous endoscopic gastrojejunostomy and reported outcomes of direct percutaneous endoscopic jejunostomy placement. SUMMARY: Enteral nutrition access can be obtained by a variety of methods depending on local expertise and resources. Endoscopic approaches have equivalent or better outcomes than other methods; however, these methods may still have limitations and distinct complications.
