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…

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. …

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 …

STUDY OBJECTIVE: To investigate the feasibility of magnetic resonance imaging (MRI) in detecting and classifying adhesions between pelvic organs caused by endometriosis, comparing MRI findings to those obtained by laparoscopy. DESIGN: Pros…

OBJECTIVE: The evolution of nerve-sparing surgery has been supported by a growing body of literature on anatomic details, dissection techniques, and functional outcomes, suggesting that nerve-sparing surgery for deep endometriosis (DE) redu…

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…

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…

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…

Introduction: The prognosis of ureteral endometriosis is good if proper treatment is applied, but lack of subjective symptoms often lead to poor treatment. The disease comprises as low as 0.1％ of all pelvic endometriosis and 10％ of urinary …

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…

OBJECTIVE: To examine the association between ovarian conservation and oncologic outcome in surgically-treated young women with early-stage, low-grade endometrial cancer. METHODS: This multicenter retrospective study examined women aged <5…

OBJECTIVE: To evaluate the effect of dienogest (DNG) in preventing the occurrence of pain and endometriomas after laparoscopic resection of uterosacral ligaments (USLs) with deep infiltrating endometriosis (DIE). STUDY DESIGN: This retrosp…
