A Targeted Biopsy during Menstruation for the Definitive Diagnosis of Rectovaginal Endometriosis: A Report of Two Cases

et al. 2021

View full text Add to dashboard Cite

We herein report the definitive diagnosis of rectovaginal endometriosis in two cases. Case 1 involved a 46-year-old woman with abdominal pain and hematochezia. The diagnosis after the first and second examinations using lower gastrointestinal (GI) endoscopy was unclear. Differential diagnoses included mucosa-associated lymphoid tissue and colorectal cancer. The third lower GI endoscopy with a targeted biopsy, performed during menstruation, confirmed rectovaginal endometriosis. Case 2 involved a 38-year-old woman with hematochezia. Lower GI endoscopy during menstruation revealed rectovaginal endometriosis. When rectovaginal or bowel endometriosis is suspected, lower GI endoscopy and a targeted biopsy during menstruation can prevent unnecessary surgery.
