Although often asymptomatic, such lesions may rarely manifest as acute bowel obstruction. Case: We report a 42-year-old woman who presented with small bowel ileus caused by deep-infiltrating endometriosis (DIE). Imaging revealed a right ovarian endometrioma with severe adhesions resulting in a distal ileal transition point. After partial decompression with conservative treatment, laparoscopic adhesiolysis with right salpingo-oophorectomy and left salpingectomy was undertaken. Intraoperative findings revealed dense adnexal\u2013ileal adhesions without transmural involvement. Postoperative hormonal suppression was instituted. Conclusions: This rare case demonstrates small bowel obstruction caused by DIE adhesions without intestinal invasion. Preoperative imaging facilitated a minimally invasive approach, while combined surgical and hormonal therapy was associated with reduced recurrence risk. These findings expand the recognized spectrum of endometriosis-related intestinal complications and support tailored management strategies.<\/jats:p>","DOI":"10.3390\/jcm15041664","type":"journal-article","created":{"date-parts":[[2026,2,23]],"date-time":"2026-02-23T10:00:52Z","timestamp":1771840852000},"page":"1664","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Deep-Infiltrating Endometriosis Causing Acute Mechanical Intestinal Obstruction Without Intestinal Invasion: A Case Report with Diagnostic and Surgical Insights"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9002-2945","authenticated-orcid":false,"given":"Jung Hyun","family":"Park","sequence":"first","affiliation":[{"name":"Division of Reproductive Endocrinology, Department of Obstetrics and Gynecology, College of Medicine, The Catholic University of Korea, Seoul 06591, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-5630-6152","authenticated-orcid":false,"given":"Jeonghyeon","family":"Shin","sequence":"additional","affiliation":[{"name":"Division of Reproductive Endocrinology, Department of Obstetrics and Gynecology, College of Medicine, The Catholic University of Korea, Seoul 06591, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mee-Ran","family":"Kim","sequence":"additional","affiliation":[{"name":"Division of Reproductive Endocrinology, Department of Obstetrics and Gynecology, College of Medicine, The Catholic University of Korea, Seoul 06591, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,2,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"556","DOI":"10.14744\/tjtes.2025.85691","article-title":"Intestinal endometriosis: A rare cause of acute care surgery","volume":"31","author":"Kutluk","year":"2025","journal-title":"Turk.
