This case report describes a 38-year-old woman who was urgently hospitalized for abdominal pain and diagnosed with intestinal obstruction; an ileus tube was placed but her symptoms worsened, leading to emergency surgery on hospital day 5. Intraoperatively, the ileocecal region was inflamed and adherent, requiring a wide ileocecal resection including the ileum, and pathology confirmed intestinal endometriosis. After surgery the postoperative course was favorable, but during follow-up she had menstrual-related hematochezia, prompting colonoscopy that showed a stricture in the sigmoid colon; hormonal therapy was then ongoing for endometriosis at that site. The paper emphasizes that intestinal endometriosis is difficult to diagnose preoperatively because it lacks distinctive imaging findings and notes only 38 reported cases (including this one) of ileal endometriosis presenting with obstruction, highlighting this major limitation. This paper is centrally about endometriosis — it reports a ileal endometriosis case presenting with intestinal obstruction and discusses diagnostic challenges.

Abstract

患者は38歳・女性. 腹痛にて緊急入院となった. 腸閉塞と診断しイレウス管を挿入するも, 腹部症状は悪化し, 入院後第5病日に緊急手術を施行した. 回盲部は炎症で一塊となり, 回腸を含めた広範な回盲部切除を行った. 病理組織学的所見にて腸管子宮内膜症と診断した. 術後経過良好で第19病日に退院した. 退院後, 月経時の下血のため, 大腸内視鏡を施行し, S状結腸部に狭窄を認めた. 現在同部位の子宮内膜症に対し, ホルモン療法を施行中である. 腸管子宮内膜症は, 子宮内膜組織の異所性増殖を示す. 腸閉塞をきたした回腸子宮内膜症は自験例を含め38例の報告のみである. 腸管子宮内膜症は画像診断で特徴的な所見が得られず術前診断は困難である. 術前診断が困難である女性の腸閉塞症例では腸管子宮内膜症も念頭におく必要がある.
