Endoscopic evaluation of fundoplication wrap integrity can be challenging. Our primary aim in this pilot study was to evaluate the accuracy and confidence of assessing Nissen fundoplication integrity and hiatus herniation among gastroenterology (GI) fellows, subspecialists, and foregut surgeons.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods<\/jats:title>\n                  <jats:p>Five variations of post-Nissen fundoplication anatomy were included in a survey of 20 sets of EGD images that was completed by GI fellows, general GI attendings, esophagologists, and foregut surgeons. Accuracy, diagnostic confidence, and inter-rater agreement across providers were evaluated.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>There were 31 respondents in the final cohort. Confidence in pre-survey diagnostics significantly differed by provider type (mean confidence out of 5 was 1.8 for GI fellows, 2.7 for general GI attendings, 3.6 for esophagologists, and 3.6 for foregut surgeons, P\u00a0=\u20090.01). The mean overall accuracy was 45.9%, which significantly differed by provider type with the lowest rate among GI fellows (37%) and highest among esophagologists (53%; P\u00a0=\u20090.01). The accuracy was highest among esophagologists across all wrap integrity variations. Inter-rater agreement was low across wrap integrity variations (Krippendorf\u2019s alpha &amp;lt;0.30), indicating low to no agreement between providers.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>In this multi-center survey study, GI fellows had the lowest accuracy and confidence in assessing EGD images after Nissen fundoplication, whereas esophagologists had the highest. Diagnostic confidence varied considerably and inter-rater agreement was poor. These findings suggest experience may improve confidence, but highlight the need to improve the evaluation of fundoplication wraps.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1093\/dote\/doab078","type":"journal-article","created":{"date-parts":[[2021,12,29]],"date-time":"2021-12-29T00:13:57Z","timestamp":1640736837000},"source":"Crossref","is-referenced-by-count":12,"title":["Variability in endoscopic assessment of Nissen fundoplication wrap integrity and hiatus herniation"],"prefix":"10.1093","volume":"35","author":[{"given":"Erin J","family":"Song","sequence":"first","affiliation":[{"name":"Department of Medicine, Duke University, Durham, NC, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7872-2033","authenticated-orcid":false,"given":"Rena","family":"Yadlapati","sequence":"additional","affiliation":[{"name":"Division of Gastroenterology, University of California San Diego, La Jolla, CA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joan W","family":"Chen","sequence":"additional","affiliation":[{"name":"Division of Gastroenterology, University of Michigan, Ann Arbor, MI, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alice","family":"Parish","sequence":"additional","affiliation":[{"name":"Department of Biostatistics and Bioinformatics, Duke University, Durham, NC, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthew J","family":"Whitson","sequence":"additional","affiliation":[{"name":"Division of Gastroenterology, Zucker School of Medicine at Hofstra-Northwell, Manhasset, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Karthik","family":"Ravi","sequence":"additional","affiliation":[{"name":"Division of Gastroenterology, Mayo Clinic, Rochester, MN, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7214-5901","authenticated-orcid":false,"given":"Amit","family":"Patel","sequence":"additional","affiliation":[{"name":"Division of Gastroenterology, Duke University, Durham, NC, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dustin A","family":"Carlson","sequence":"additional","affiliation":[{"name":"Division of Gastroenterology, Northwestern University, Chicago, IL, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abraham","family":"Khan","sequence":"additional","affiliation":[{"name":"Division of Gastroenterology, New York University-Langone Health, New York, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Donna","family":"Niedzwiecki","sequence":"additional","affiliation":[{"name":"Department of Biostatistics and Bioinformatics, Duke University, Durham, NC, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6350-3906","authenticated-orcid":false,"given":"David A","family":"Leiman","sequence":"additional","affiliation":[{"name":"Division of Gastroenterology, Duke University, Durham, NC, USA"},{"name":"Duke Clinical Research Institute, Duke University, Durham, NC, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2021,12,29]]},"reference":[{"issue":"6","key":"2022051713441703200_ref1","doi-asserted-by":"crossref","first-page":"1798","DOI":"10.1053\/gast.1997.v112.pm9178669","article-title":"Speed of healing and symptom relief in grade II to IV gastroesophageal reflux disease: a meta-analysis","volume":"112","author":"Chiba","year":"1997","journal-title":"Gastroenterology"},{"issue":"16","key":"2022051713441703200_ref2","doi-asserted-by":"crossref","first-page":"1700","DOI":"10.1056\/NEJMcp0804684","article-title":"Clinical practice.
