OBJECTIVE: To analyse the anatomy and classification of JPDD and its relationship with biliary and pancreatic disorders, and to explore the diagnostic value of multi-slice spiral computed tomography (MSCT) in patients with JPDD. METHODS: The imaging data of patients with JPDD, which was obtained via abdominal computed tomography examination and confirmed via gastroscopy and\/or upper gastrointestinal barium enema, in our hospital from 1 January 2019 to 31 December 2020 were retrospectively analysed. All patients were scanned using MSCT, and the imaging findings, classification and grading were analysed. RESULTS: A total of 119 duodenal diverticula were detected in 96 patients, including 73 single diverticula and 23 multiple diverticula. The imaging findings were mainly cystic lesions of the inner wall of the duodenum protruding to the outside of the cavity. The thin layer showed a narrow neck connected with the duodenal cavity, and the shape and size of the diverticula were different: 67 central-type cases and 29 peripheral-type cases. There were 50 cases of type I, 33 cases of type II, 19 cases of type III and six cases of type IV. Furthermore, there were seven small, 87 medium and 14 large diverticula. The differences in the location and size of the JPDD in MSCT grading were statistically significant (P&lt; 0.05). CONCLUSION: The MSCT method has an important diagnostic value for the classification of JPDD, and MSCT images are helpful in the clinical evaluation of patients with JPDD and the selection of treatment options.<\/jats:p>","DOI":"10.3233\/thc-220742","type":"journal-article","created":{"date-parts":[[2023,6,2]],"date-time":"2023-06-02T13:34:18Z","timestamp":1685712858000},"page":"1-8","source":"Crossref","is-referenced-by-count":3,"title":["Multi-slice spiral computed tomography diagnosis of juxta-papillary duodenal diverticulum and its relationship with biliopancreatic diseases"],"prefix":"10.1177","volume":"32","author":[{"given":"Zhongwei","family":"Li","sequence":"first","affiliation":[{"name":"Department of Radiology, Yantaishan Hospital, Yantai, Shandong, China"},{"name":"Department of Radiology, Yantaishan Hospital, Yantai, Shandong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Di","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Radiology, 970 Hospital of the PLA JLSF, Yantai, Shandong, China"},{"name":"Department of Radiology, Yantaishan Hospital, Yantai, Shandong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiashou","family":"Hu","sequence":"additional","affiliation":[{"name":"Department of Radiology, 970 Hospital of the PLA JLSF, Yantai, Shandong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guowei","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Radiology, Yantaishan Hospital, Yantai, Shandong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jinfeng","family":"Sun","sequence":"additional","affiliation":[{"name":"Department of Radiology, 970 Hospital of the PLA JLSF, Yantai, Shandong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","reference":[{"issue":"48","key":"10.3233\/THC-220742_ref1","doi-asserted-by":"publisher","first-page":"830","DOI":"10.3238\/arztebl.2020.0830b","article-title":"Duodenal diverticulum as the cause of unexplained duodenal stenosis","volume":"117","author":"Thakran","year":"2020","journal-title":"Dtsch Arztebl Int."},{"issue":"1","key":"10.3233\/THC-220742_ref2","doi-asserted-by":"publisher","first-page":"57","DOI":"10.17235\/reed.2021.8258\/2021","article-title":"Lemmel\u2019s syndrome: An uncommon complication of periampullary duodenal diverticulum","volume":"114","author":"Mart\u00edn","year":"2022","journal-title":"Rev Esp Enferm Dig."},{"issue":"8","key":"10.3233\/THC-220742_ref3","doi-asserted-by":"publisher","first-page":"e16959","DOI":"10.7759\/cureus.16959","article-title":"Lemmel\u2019s syndrome secondary to common bile duct compression by an inflamed duodenal diverticulum","volume":"13","author":"Gao","year":"2021","journal-title":"Cureus."},{"issue":"3","key":"10.3233\/THC-220742_ref4","doi-asserted-by":"publisher","first-page":"1147","DOI":"10.1016\/j.radcr.2022.11.013","article-title":"Lemmel syndrome: An unusual cause of biliary obstruction secondary to a duodenal juxta-ampullary diverticulum: A report of two cases","volume":"18","author":"Houssni","year":"2023","journal-title":"Radiol Case Rep."},{"key":"10.3233\/THC-220742_ref5","doi-asserted-by":"publisher","first-page":"106698","DOI":"10.1016\/j.ijscr.2021.106698","article-title":"Lemmel\u2019s syndrome: Presentation of an uncommon cholangitis cause and a risk factor for failed endoscopic retrograde cholangiopancreatography.
