Comparison of surgical outcomes between robot-assisted and conventional laparoscopic nerve-sparing modified radical hysterectomy for deep endometriosis.

Purpose: Drug resistance and severe pelvic pain often warrant surgical intervention for treating deep endometriosis (DE); however, damage to the autonomic nervous system can occur because of anatomical considerations. We aimed to investigate the advantages of robotic technology in enabling precise dissection, even in DE.

Methods: We retrospectively compared the surgical outcomes of robot-assisted (RA) and conventional laparoscopic (CL) nerve-sparing modified radical hysterectomies (NSmRHs) for DE.

Segmental Bowel Resection for Rectal Endometriosis Using the da Vinci SP.

Objective: The da Vinci SP Surgical System (SP) received regulatory approval for use in gynecological surgeries in Japan in 2023. Given the advantages of the precision of a robot, less pain, and the cosmesis of single-port surgery, the da Vinci SP is expected to be further used for minimally invasive surgeries. To the best of our knowledge, this is the first report of the use of SP for the treatment of rectal endometriosis with segmental bowel resection.

Effect of Uterine Weight on the Surgical Outcomes of Robot-Assisted Hysterectomy in Benign Indications.

Background Uterine weight is an important factor in determining the complexity of a hysterectomy. Although greater uterine weight increases operative time and blood loss in open or laparoscopic surgery, it remains uncertain whether this applies to robot-assisted hysterectomy. This study aimed to investigate the effect of uterine weight on the surgical outcomes of robot-assisted hysterectomy.

Nerve-sparing surgery for deep lateral parametrial endometriosis.

Objective: Although dLPE is not overly rare, isolation of the autonomic nerves from dLPE cannot always be guaranteed. In patients with endometriosis lesions that are embedded in the deep parametrium, nerve-sparing techniques are no longer considered feasible, except for those with unilateral involvement. However, even one-sided radical parametrectomy may actually lead to bladder dysfunction, which seriously affects the quality of life.

Design: Retrospective cohort study of consecutive patients who underwent surgery for the ureter endometriosis with hydronephrosis.

Setting: A private hospital that provide primary, secondary and tertiary care.

Robot-assisted Exploration of Somatic Nerves in the Pelvis and Transection of the Sacrospinous Ligament for Alcock Canal Syndrome.

Study Objective: Some articles have reported the surgical management of Alcock canal syndrome (ACS) using the transperineal [1], transgluteal [2], or conventional laparoscopic approach [3,4]. In 2015, Rey and Oderda [5] reported the first robotic neurolysis of the pudendum, providing the advantages of robot-assisted surgery: magnified and 3-dimensional vision and greater precision of movements. However, to our knowledge, there have been no reports on the use of a robotic platform for the treatment of ACS in the field of gynecology.

Robot-assisted total extraperitoneal para-aortic and pelvic lymphadenectomy.

Pregnancy complications and glucose intolerance in women with polycystic ovary syndrome.

Polycystic ovary syndrome (PCOS) is a common endocrine disorder characterized by insulin resistance and hyperandrogenism. The interaction of these factors might result in increased risks of miscarriage and pregnancy complications such as gestational diabetes mellitus (GDM). To examine the pregnancy risks in women with PCOS, we compared obstetrical outcomes between patients with and without PCOS.

A 30-year-old woman, gravida 3, para 3, presenting with placentomegaly, was referred to our department at 18 weeks of gestation. An ultrasonography revealed a normal fetus with a large multicystic placenta, measuring 125 × 42 × 80 mm.

[Survey on oncologists-provided information on treatment-related infertility to breast cancer patients].

Purpose: Treatment-related infertility is an important issue facing breast cancer survivors of childbearing age. A previous study at the National Cancer Center Hospital between 2000 and 2004 analyzed 136 postoperative breast cancer patients under 40 years old, and found that only 7% of them had been provided with information on fertility-related issues by their treating physicians. However, the way in which information is shared may have changed, given the recent publication of national and international guidelines on fertility issues in cancer patients, and we hypothesized that there will be an increase in the percentage of cases in which information about fertility-related issues is provided.
