Transvaginal lymphatic embolization of the fistula between a pelvic lymphocele and the vaginal stump following radical hysterectomy and sentinel pelvic lymph node biopsy in a patient with cervical cancer: A case report

A lymphocele is a common complication that occurs following pelvic lymph node dissection. However, the complication of lymphoceles following sentinel pelvic lymph node biopsy has not been previously reported, to the best of our knowledge. A 49-year-old female patient had undergone radical hysterectomy and pelvic lymph node biopsy for stage IB1 cervical cancer 5 months previously and presented with a profuse watery vaginal discharge of liters per day. A fistula connecting the lymphocele and the vaginal stump was identified using lymphoscintigraphy and single photon emission CT/CT. Transvaginal lymphatic embolization was successfully performed through the vaginal fistulous tract, resulting in immediate reduction of the vaginal discharge. In conclusion, the case of fistula formation between pelvic lymphocele and vaginal stump was encountered at our department and was reported with a literature review. To the best of our knowledge, there are no previous reports on lymphoceles with direct communication to the vaginal mucosa, particularly following sentinel pelvic lymph node biopsy. The present study reported the case of a patient who was successfully treated for a pelvic lymphocele with direct communication to the vaginal mucosa.
