Prolapsed uterine fibroids are pedunculated submucous fibroids that prolapse through the cervical canal. Herein, we describe the laparoscopic treatment of massive prolapsed submucous fibroids. A 47-year-old woman had experienced frequent urination and abnormal vaginal bleeding for 7 years. She presented with persistent lower abdominal pain. The uterine fundus was palpable at 3 cm above the umbilicus. Vaginal examination revealed a dark purple and easily bleeding mass in her vagina. Pelvic magnetic resonance imaging revealed a large mass prolapsing from the uterine endometrium, which occupied the cervical canal and vagina, without evidence of malignancy. Under a preoperative diagnosis of uterine fibroids with edematous degeneration, we performed laparoscopic uterine artery cutting, transvaginal removal of the fibroid by twisting, and total laparoscopic hysterectomy. Histopathological examination revealed leiomyoma with partial ischemia. Six days postoperatively, the patient was discharged without complications. This approach may be appropriate for the treatment of massive prolapsed submucous fibroids.
