This paper reports a 47-year-old woman admitted for constipation that occurred at menses, with investigations using barium enema, colonoscopy, CT, and MRI identifying whole-circumference rectal stenosis covered by normal mucosa, a structure between the uterus and rectum, and a right ovarian cyst. The authors diagnosed rectal endometriosis and treated her with hormone therapy for one year, but she had no remission of cyclic constipation and experienced side effects. Surgical management with partial rectal resection and total hysterectomy was performed, and operative findings showed firm uterine–rectal adhesion and a chocolate cyst at the right ovary, with histopathology demonstrating endometrial cells with fibrotic change in the rectal submucosal layer. The paper notes that intestinal endometriosis is relatively rare and that preoperative diagnosis is often difficult, which it presents as a key limitation relevant to management decisions. This paper is centrally about endometriosis — a case report of rectal endometriosis causing menses-related constipation and diagnosed via imaging with confirmation on histopathology.

Abstract

A 47-year-old woman was admitted to the hospital because of constipation at menses. Barium enema study and a colonoscopy revealed a whole-circumference stenosis in the rectum covered with normal mucosa. CT and magnetic resonance imaging (MRI) revealed a restiform structure between the uterus and rectum, and also revealed a right ovarian cyst. In the light of these findings, we diagnosed the case as rectal endometriosis. In spite of the hormone therapy for a year. no remission in constipation at menses was attained. What is worse, side effect of the hormone therapy occurred. Therefore, a partial rectal resection and a total hysterectomy were performed. The operative findings showed a firm adhesion between the uterus and rectum and a chocolate cyst at the right ovarium. Histopathologically, endometrial cells with fibrotic change were seen in the submucosal layer of the rectum. Endometriosis is characterized by ectopic proliferation of endometrial cells. Intestinal endometriosis is relatively rare disease and only 84 cases have been reported in the Japanese literature up to now. It is often difficult to make definite diagnosis preoperatively and careful attitude is essential to indicate operation and to select therapeutic tactics.
