The white light endoscopic image showed a lesion in the distal proximal horizontal part of the descending duodenum, identified as laterally spreading tumours, non-granular type, flat-elevated type (LST-NG-F). The pathological diagnosis was tubular villous adenoma with high-grade intraepithelial neoplasia. Endoscopic narrow-band imaging revealed disordered mucosal glandular duct openings, disrupted mucosal microvascular arrangement, and a clear boundary between the pathological tissue and the surrounding tissue. After obtaining informed consent, the surgical resection was performed using a treatment strategy involving rubber band ligature and electrotomy. A resection specimen measuring 1.4\u00d72cm was obtained, with negative postoperative resection margins.\nKeywords: Duodenal tumour, adenoma, intraepithelial neoplasia, digestive system endoscopic surgery.<\/jats:p>","DOI":"10.47391\/jpma.20313","type":"journal-article","created":{"date-parts":[[2025,8,28]],"date-time":"2025-08-28T16:06:46Z","timestamp":1756397206000},"page":"1456-1458","source":"Crossref","is-referenced-by-count":0,"title":["Endoscopic resection of lateral spreading tumours in the distal descending segment of duodenum: a rare case report"],"prefix":"10.47391","volume":"75","author":[{"given":"Qi","family":"Yao","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xingming","family":"Ji","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ye","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"26547","published-online":{"date-parts":[[2025,8,26]]},"container-title":["Journal of the Pakistan Medical Association"],"original-title":[],"link":[{"URL":"https:\/\/jpma.org.pk\/index.php\/public_html\/article\/download\/20313\/4318","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/jpma.org.pk\/index.php\/public_html\/article\/download\/20313\/4318","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,9,1]],"date-time":"2025-09-01T16:05:14Z","timestamp":1756742714000},"score":1,"resource":{"primary":{"URL":"https:\/\/jpma.org.pk\/index.php\/public_html\/article\/view\/20313"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,8,26]]},"references-count":0,"journal-issue":{"issue":"09","published-online":{"date-parts":[[2025,8,28]]}},"URL":"https:\/\/doi.org\/10.47391\/jpma.20313","relation":{},"ISSN":["0030-9982","0030-9982"],"issn-type":[{"type":"electronic","value":"0030-9982"},{"type":"print","value":"0030-9982"}],"subject":[],"published":{"date-parts":[[2025,8,26]]}}}
