A case report describes a woman in her forties with constipation and cyclic abdominal pain, where histopathology confirmed intestinal endometriosis causing sigmoid colon stricture despite the rarity of such circumferential stenosis.

This case report describes a woman in her forties presenting with constipation and dyschezia, where abdominal pain exacerbated during menstruation led to the discovery of a sigmoid colon stricture via colonoscopy. Although imaging ruled out obvious neoplastic lesions, histopathological examination of a biopsy from the reddened mucosal site confirmed the presence of endometrial tissue, establishing a diagnosis of intestinal endometriosis. The authors note that circumferential stenosis caused by this condition is rare and emphasize the importance for endoscopists to suspect the disease based on menstrual-related symptoms and to communicate this suspicion to pathologists during biopsy procedures. This paper is centrally about endometriosis — specifically the gastrointestinal manifestation known as intestinal endometriosis causing bowel obstruction.

Abstract

The patient was a woman in her 40s who was referred to our hospital with chief complaints of constipation and abdominal pain during defecation. Colonoscopy at her previous doctor pointed out stricture in the sigmoid colon. Abdominal pain was characterized by aggravation during menstruation. A biopsy was performed from the reddened site as a differential diagnosis of metastatic tumor, intestinal endometriosis, etc. Abdominal and pelvic contrast-enhanced computed tomography revealed no obvious neoplastic lesions. Histopathological examination identified endometrial tissue in the biopsy specimen and reached the diagnosis of intestinal endometriosis. Reports of intestinal endometriosis with circumferential stenosis are rare.

症例 内腔狭窄を来した腸管子宮内膜症の1例 2023 年 103 巻 1 号 p. 109-111 詳細 抄録 The patient was a woman in her 40s who was referred to our hospital with chief complaints of constipation and abdominal pain during defecation. Colonoscopy at her previous doctor pointed out stricture in the sigmoid colon. Abdominal pain was characterized by aggravation during menstruation. A biopsy was performed from the reddened site as a differential diagnosis of metastatic tumor, intestinal endometriosis, etc. Abdominal and pelvic contrast-enhanced computed tomography revealed no obvious neoplastic lesions. Histopathological examination identified endometrial tissue in the biopsy specimen and reached the diagnosis of intestinal endometriosis. Reports of intestinal endometriosis with circumferential stenosis are rare. It is important for the endoscopist to first suspect this disease based on the patient's medical history, and when the exposed lesion is shown on the mucosal surface, the endoscopist should perform a biopsy and inform the pathologist of the suspicion of intestinal endometriosis. © 2023 一般社団法人 日本消化器内視鏡学会 関東支部
