If there is a main bowel lesion then a resection margin of greater than 2 cm should be attempted [11]. However, our case helps demonstrate that it can be difficult to exclude a malignancy intra-operatively [3, 20]. In such cases, it is appropriate to carry out an oncological resection. Post-operative hormonal therapy is advocated by some, however recent meta-analysis have failed to demonstrate any benefits [1, 21]. Conclusions Acute bowel obstruction secondary to intestinal endometriosis remains a difficult condition to diagnose without an elevated index of suspicion. Endometriosis as

a differential should be borne in mind when assessing females of a reproductive age who present with small bowel obstruction. A careful Crenigacestat purchase history may elicit symptoms related to the patient’s menses and in conjunction selleckchem with equivocal CT findings should raise the possibility of intestinal endometriosis. If the condition is suspected

then a pre-operative MRI small bowel is indicated. Exclusion of bowel malignancy is essential and if in doubt an oncological resection should be performed.
