Endometriosis is a commonly encountered problem in women of reproductive age. It usually causes chronic abdominal pain. However, it rarely causes complications such as intestinal obstruction. The most commonly performed procedure for these patients is bowel resection and anastomosis. Unless it is complicated with anastomotic leakage. We present a 39-year-old woman presented with intestinal obstruction due to appendiceal and ileal endometriosis complicated with anastomotic leakage after surgery.
