胆石症術後に腸閉塞をきたした回腸子宮内膜症の1例

The patient was a 34-year-old woman, who was treated with hormone therapy for endometriosis. She visited local doctor because of upper abdominal pain. She was detected cholelithiasis and consulted our hospital. She was treated with low-dose pill （LUNABELL®） which has a risk of thrombosis. After 4-weeks drug withdrawal, we operated laparoscopic cholecystectomy. Histopathological examination showed chronic cholecystitis. The 24th post-operative day, she had ileus due to a terminal ileum stenosis. An ileocecal resection was performed. Intestinal endometriosis was confirmed on pathological examination. There is a possibility that first symptoms caused by the intestinal endometriosis or progressed by the interruption of hormone therapy. We should keep in mind intestinal endometriosis especially in endometriosis patients as the underlying disease with digestive symptoms.
