Small bowel obstruction caused by endometriosis in a postmenopausal woman.

We report a rare case of small bowel obstruction (SBO) caused by endometriosis in a postmenopausal woman. A 54-year-old postmenopausal woman presented with severe abdominal pain and vomiting. Before menopause, she sometimes had abdominal pain associated with menses. Axial multi-dimensional CT images revealed a SBO with small nodules near the terminal ileum. The obstruction was diagnosed as being caused by small bowel endometriosis. Curved planar reconstruction images showed a complicated obstruction of the small intestine 15 cm from the terminal ileum. Based on the stenotic lesion, a SILS procedure was performed. The patient's SBO diagnosis was histologically confirmed as being caused by small bowel endometriosis. SILS was deemed to be a safe, feasible procedure for treating this bowel obstruction. Curved planar reconstruction images were useful in preoperative imaging and diagnosis of SBO, especially as they were able to highlight the constricting legion.
