This study compared surgical approaches and perioperative outcomes of nerve-sparing modified radical hysterectomy (NSmRH) for deep endometriosis (DE) using the da Vinci SP and Xi systems. This retrospective cohort study included consecutive…

Minimally invasive surgery, especially laparoscopic surgery, remains the standard treatment for endometriosis; however, robotic-assisted surgery (RAS) is also gaining adoption. Several meta-analyses have reported comparable perioperative ou…

PURPOSE: To characterize early learning curves for two gynecologic oncologists and their first assistants using the Hugo robotic-assisted surgery system for hysterectomy in benign uterine disease or FIGO stage IA endometrial cancer. METHOD…

Identification and preservation of pelvic autonomic nerves is essential for preventing postoperative functional disorders during surgery for deep endometriosis (DE); however, nerve-sparing surgery in patients with severe fibrosis and cul-de…

To compare the surgical outcomes of robot-assisted hysterectomy (RAH) for benign diseases using da Vinci SP (SP) and da Vinci Xi (Xi). A retrospective study with propensity score matching (PSM) analysis. An urban general hospital in Japan. …

We aimed to generate immortalized stromal cell lines from the ovarian and fallopian tube tissues of a single patient using Sendai virus (SeV) vectors and identify candidate stromal genes involved in ovarian carcinogenesis. Tissues were coll…

BACKGROUND: Although the benefit of nerve-sparing surgery for deep endometriosis (DE) with postoperative voiding dysfunction has been demonstrated, it requires a high level of surgical skill to accurately remove endometriosis lesions while …

BACKGROUND: This study evaluated the effectiveness of preoperative inflammatory response markers in distinguishing clear cell carcinoma (CCC) and endometrioid carcinoma (EC) from ovarian endometrioma. METHODS: Patients with stage I ovarian…

OBJECTIVE: To evaluate the safety and pharmacokinetics/pharmacodynamics of AMY109, an anti-interleukin-8 recycling antibody in a first-in-human phase 1 trial in healthy volunteers (HVs) and patients with endometriosis. DESIGN: A multicente…

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 V…

OBJECTIVE: Ureteroneocystostomy should be considered in cases of severe ureteral endometriosis when ureteral lesions are near the bladder insertion, or the lesions involve the ureteral wall along a large extent of the pelvic ureter, making …

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 investigat…

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 app…

OBJECTIVE: To demonstrate the anatomical and technical highlights of nerve-sparing deep endometriosis (DE) surgery with rectal discoid resection using a newer single-port robotic system. DESIGN: Step-by-step demonstration of this method wa…

BACKGROUND: This study assesses the feasibility of minimally invasive surgery (MIS) for well-selected epithelial ovarian cancer (EOC) patients. METHODS: We performed a review of data prospectively collected from a single center from 2017 t…

Malignant pericardial effusion is an uncommon metastatic manifestation of ovarian carcinoma. Few cases of ovarian serous carcinoma have been previously reported. Ovarian clear cell carcinoma is the second most common histologic subtype in E…

Uterine adenomyosis is an estrogen-dependent tumor and one of the most common benign diseases in sexually mature women. The frequency of endometrial cancer associated with adenomyosis has been reported to be 18%-66%. On the other hand, endo…

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 c…

STUDY OBJECTIVE: To investigate the short-term outcomes of laparoscopic ureteroneocystostomy in patients with ureteral endometriosis (UE). DESIGN: Retrospective cohort study of consecutive patients who underwent surgery for the ureter endo…

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 r…

OBJECTIVE: To describe the anatomic and technical highlights of a novel nerve-sparing surgery in deep endometriosis (DE) using near-infrared (NIR) fluorescence technology and indocyanine green (ICG). DESIGN: Stepwise demonstration of this …

Abstract Study Objective: To investigate the short-term outcomes of laparoscopic ureteroneocystostomy in patients with ureteral endometriosis (UE). Design: Retrospective cohort study of consecutive patients who underwent surgery for the ur…

OBJECTIVE: To demonstrate anatomic and technical highlights of a robot-assisted nerve plane-sparing eradication of deep endometriosis (DE). DESIGN: Stepwise demonstration of the technique with narrated video footage. SETTING: An urban gen…

OBJECTIVE: To show technical highlights of a nerve-sparing laparoscopic eradication of deep endometriosis (DE) with posterior compartment peritonectomy. DESIGN: Demonstration of the technique with narrated video footage. SETTING: An urban…

Study Objective To report the application of the double bipolar technique in a patient with 1b1 cervical cancer who wished to preserve her fertility potential. Design After experiencing 105 cases of laparoscopic and robotic radical trachele…
