Transmural sigmoid colon endometrioma in a young reproductive age woman

Introduction: Endometriosis is a common disease affecting women of reproductive age. Endometrial tissue can implant to various tissues including gastrointestinal tissues and cause significant GI symptoms. Rarely, these implants cause constricting lesions that require surgical intervention. Presentation of Case: We report a case of a 27-year-old woman with extensive endometriosis and new onset gastrointestinal symptoms. A near-complete constricting endometrioma involving the sigmoid colon was identified and required surgical resection with side-to-side anastomosis. DISCUSSION: When endometrial tissue implants to gastrointestinal tissues it can cause GI symptoms including rectal bleeding and dyschezia. If left untreated, progressive endometriosis may result in partial or complete bowel obstruction requiring surgical resection. Conclusion: Obstruction of the GI tract by endometrial implantation can be prevented with early identification and treatment (medical and surgical).
