A 29-year-old woman with lower abdominal pain, high fever, and a leukocyte count of 11,200_mm3 was found in An abdominal computed tomography (CT) to have a low-density mass in the right obturator canal suggesting right obturator hernia. After 2 days of conservative antibiotic treatment before mechanical ileusand ischemic change in some organs were recognized, she was referred forlower right quadrant tenderness and muscle guarding. Laparoscopic examination showed the right fallopian tube to be swollen and tightly incarcerated in the right obturator canal. The fallopian tube was removed from the canal and the pelvic obturator canal orifice was closed. The fallopian tube was nonnecrotic preserved. Obturator hernia in young woman is rare and fallopian tube incarceration has not, to our knowledge, been previously reported. The laparoscopic approach is thus useful for diagnosing and treating obturator hernia.
