Appendectomy in retrograde order for complete removal of endometriosis

Endometriosis frequently involves the intestines. Appendectomy would be often required as part of complete removal of endometriosis. We present a patient with endometriosis who required very difficult appendectomy. For complete removal of endometriosis, hysterectomy, bilateral salpingooophorectomy, low anterior resection and accompanying pelvic peritonectomy were performed through a mid-line incision. Unexpectedly, the appendiceal tip was attached to peri-hepatic tissue with the appendix adhered to the surrounding peritoneum and bowel. Completion of the appendectomy was possible in retrograde order after extension of the surgical incision above the umbilicus. Our findings suggest that preoperative image evaluation for location or position of the appendix might be helpful in patients with suspected endometriosis to offer correct counselling, obtaining adequate consent, determining the optimal surgical approach and scheduling opportune intraoperative consultation by a colorectal surgeon.
