Factors affecting gasless reduced-port laparoscopic myomectomy (GRP-LM) using a subcutaneous abdominal wall lifting method: a retrospective analysis of a large cohort of 966 cases in Japan.

Objective: To evaluate the usefulness of gasless reduced-port laparoscopic myomectomy (GRP-LM) using a subcutaneous abdominal wall lifting method.

Methods: In GRP-LM, after lifting the abdominal wall by a subcutaneous abdominal wall lifting method, a 1.5-cm incision is made in the lateral abdomen, Lap Protector is placed.

Clinical application of virtual hysteroscopy by CO(2)-multidetector-row computed tomography to submucosal myomas.

Study Objective: We produced virtual hysteroscopy (VH) images from the images obtained after expanding the uterine cavity of patients with submucosal myomas and performing multidetector-row computed tomography scans, and assessed them in comparison with hysteroscopic imaging and in relation to the advantages of VH.

Design: Cohort-control study (Canadian Task Force classification II-2).

Setting: Tokyo Medical University Hospital department of obstetrics and gynecology.

Myometrial invasion and cervical invasion by endometrial carcinoma: evaluation by CO2-volumetric interpolated breathhold examination (VIBE).

Purpose: To assess myometrial invasion and cervical invasion by endometrial carcinoma, using CO2-volumetric interpolated breathhold examination (VIBE) enabling more precise evaluation of depth of tumor invasion.

Materials And Methods: CO2-VIBE was performed in 21 cases of endometrial carcinoma (Stage Ia-IIb) prior to treatment. The images were interpreted by performing multiplanar reconstruction (MPR), and the findings obtained from the images (degree of myometrial invasion and presence or absence of cervical invasion) were assessed in comparison with the histopathological diagnosis.

Dysgerminoma in a patient with a tumor of the neck. Empiric treatment of stage IV dysgerminoma.

The evolution of therapy for malignant ovarian germ cell tumors is one of the true success stories in oncology. Treatment outcome has improved greatly thanks to cisplatin-based combination chemotherapy. According to the well-established treatment guidelines for advanced cases, we treated a case of stage IV undifferentiated germ cell tumor in which we were able to preserve the patient's fertility.

Evaluation of endometrial cancer with 3D-VIBE (volume interpolated breath-hold examination) using intrauterine CO2 gas.

To evaluate the myometrial infiltration of the endometrial cancer prior to aggressive treatment, dynamic MRI (magnetic resonance imaging) has attracted attention. However, it has also been found that in a number of cases, MRI exhibits inconsistent results with regards to the extent of the infiltration into this component of the uterine body. To overcome this limitation, the authors designed a method to delineate the tumor morphology more clearly by injecting CO2 gas into the uterine cavity.
