The paper reports a clinical case of a 38-year-old woman with a known history of endometriosis who presented with abdominal pain and vomiting and was diagnosed on contrast-enhanced CT with intestinal obstruction in the ileocecal region. An ileus tube was initially used, but colonoscopy showed severe terminal ileal stenosis with erythema/edema and sigmoid erythematous mucosa, while biopsies indicated nonspecific colitis; ileus angiography suggested disruption beyond the terminal ileum. Because intestinal endometriosis was suspected, laparoscopic ileocecal resection with left adnexectomy and right salpingectomy was performed, and pathology of the resected specimens supported endometriosis as the cause, with the main limitation being that this is a single case report. This paper is centrally about endometriosis — it presents an ileal (intestinal) endometriosis case causing intestinal obstruction.

Abstract

A 38-year-old woman with a history of endometriosis visited our hospital with (complaints of) abdominal pain and vomiting. She was then admitted with a diagnosis of intestinal obstruction in the ileocecal region based on abdominal contrast-enhanced computed tomography findings, she was subsequently treated with an ileus tube. Colonoscopy showed edema and erythema, with severe stenosis such that the colonoscope couldn't pass through the terminal ileum, as well as erythematous mucosa in the sigmoid colon. Biopsies of the same area revealed nonspecific colitis. Ileus angiography showed disruption of the contrast-enhanced image beyond the terminal ileum. Suspecting intestinal endometriosis, and after consulting both the Department of Surgery and the Department of Obstetrics and Gynecology, we performed laparoscopic ileocecal resection, left adnexectomy, and right salpingectomy. The pathological findings of the surgical specimens suggested endometriosis. We herein report a case of ileal endometriosis, an infrequent cause of intestinal obstruction.
