Specialists at the Division of Gynecologic Surgery provide accurate diagnoses of benign and malignant tumors of the female genital organs (uterus, ovary, etc.) and appropriate surgical and nonsurgical treatments. Infertility, genital organ malformation, genital organ prolapse and other dysfunctions and morphological abnormalities are also treated surgically.
Medical services
About 1,000 patients are admitted for treatment annually to our department and more than 15 surgeries are performed weekly. In addition, chemotherapy and radiotherapy are provided for malignant tumors. The outpatient clinic is staffed with specialists in a variety of fields.
Diagnosis and treatment policy
Our aim is to provide optimal treatment for individual patients based on established evidence and detailed discussion among many physicians. Case review meetings in which all doctors participate and joint review meetings with relevant departments are regularly held to determine treatment strategies based on comprehensive understanding.
Specialties
An interdisciplinary treatment approach is taken which utilizes a combination
of surgical treatment, chemotherapy and radiotherapy in the majority of cases
involving malignant tumors in the uterus and organs attached to the uterus
(ovaries, oviducts). Through this approach, favorable outcomes have been
achieved. Minimally-invasive, safe, laparoscopic surgery is frequently employed
in the treatment of benign tumors, Pelvic organ prolapse and Genital anomalies.
Bone densitometry is also applied in maintaining and improving the quality of
life in menopausal women and patients who have undergone treatment for
tumors.
Target diseases
Cervical cancer, endometrial cancer, ovarian cancer, trophoblastic disease, other
malignant female genital tumors, hysteromyoma, adenomyosis, ovarian cyst,
endometriosis, ectopic pregnancy, Uterine malformations, Pelvic organ prolapse,
infertility requiring surgery, etc.
Advanced treatments/ Specialized treatments
Radical trachelectomy for women of childbearing age with early cervical cancer
We perform radical trachelectomy (a surgery including removal of uterine cervix, paracervical tissue and pelvic lymph nodes, and preserving uterine corpus and ovaries) for patients of reproductive age (≤40) with stage IB1 cervical cancer under 2cm in size.
Minimally Invasive Surgery (MIS) for gynecological oncology
We perform both laparoscopic and robotic surgery for early stage endometrial cancer. We provide all MIS covered by health insurance including laparoscopic para-aortic lymphadenectomy. We carefully consider the wishes of patients, place the highest priority on safety and curativeness, and comply with indications.
Laparoscopic or robot-assisted sacrocolpopexy for pelvic organ prolapse
Pelvic organ prolapse and urinary incontinence affect approximately 40% of
women with childbirth experience. Surgical treatment is often required for a
fundamental resolution, and sacrocolpopexy --performed laparoscopically or
with robotic assistance --is a highly effective technique with a low recurrence
rate.
Excision of adenomyotic lesions (for uterine adenomyosis)
Adenomyosis is a disease that commonly affects women in their 30s to 50s, in
which tissue similar to the endometrium develops within the muscular layer
of the uterus. At our department, we perform surgery that removes only the
adenomyotic lesions, with the aim of alleviating symptoms while preserving
the uterus. Our facility is officially recognized by the Ministry of Health, Labour
and Welfare as a designated center for the advanced medical procedure
“Adenomyotic Lesion Excision Surgery.”
