This 1994 Japanese case report describes a 40-year-old woman with constipation and bloody stool that occurred at menses, in whom imaging with barium enema showed a localized, circumferential stricture of the sigmoid colon. Preoperative biopsy did not confirm the diagnosis, and during surgery the sigmoid lesion was identified macroscopically, with definitive diagnosis made microscopically using intraoperative frozen section; the authors performed partial resection. Postoperatively, buserelin acetate was administered nasally, and the patient’s course was reported as fair, with the paper noting the main limitation that enteric endometriosis can be difficult to diagnose preoperatively. This paper is centrally about endometriosis — specifically sigmoid colon (enteric) endometriosis presenting with menses-associated constipation and bloody stool.
Abstract
Endometriosis is characterized by the ectopic proliferation of endometrial cells, and this condition also appears in the digestive tract. In Japan, colonic endometriosis is relatively rare and there are only a few case reports to our concerm. This report is to present a case of endometriosis of the sigmoid colon with a review of the reports in Japan. The patient is a 40-year-old woman suffered from constipation and bloody stool at menses. Barium enema study revealed the localized and circulated stricture in the sigmoid colon. Preoperatively, the biopsy could not confirm the diagnosis. During operation a lesion localized within the sigmoid colon was found macroscopically, and diagnosis was made microscopically by intraoperative frozen section. Partial resection of the sigmoid colon was performed. Postoperatively, buserelin acetate was administered nasally and the clinical course is fair. Enteric endometriosis may be treated by the hormonal therapy if the diagnosis can be definitely made. But actually the disease presents difficulty in correct diagnosis. When the operation is performed without accurate diagnosis, intraoperative frozen section should be done to confirm the diagnosis and the resection area should be reduced to a minimum.

Abstract
Endometriosis is characterized by the ectopic proliferation of endometrial cells, and this condition also appears in the digestive tract. In Japan, colonic endometriosis is relatively rare and there are only a few case reports to our concerm. This report is to present a case of endometriosis of the sigmoid colon with a review of the reports in Japan.
The patient is a 40-year-old woman suffered from constipation and bloody stool at menses. Barium enema study revealed the localized and circulated stricture in the sigmoid colon. Preoperatively, the biopsy could not confirm the diagnosis. During operation a lesion localized within the sigmoid colon was found macroscopically, and diagnosis was made microscopically by intraoperative frozen section. Partial resection of the sigmoid colon was performed. Postoperatively, buserelin acetate was administered nasally and the clinical course is fair.
Enteric endometriosis may be treated by the hormonal therapy if the diagnosis can be definitely made. But actually the disease presents difficulty in correct diagnosis. When the operation is performed without accurate diagnosis, intraoperative frozen section should be done to confirm the diagnosis and the resection area should be reduced to a minimum.
