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…

STUDY OBJECTIVE: Fluorescence imaging using indocyanine green (ICG) has recently gained widespread use in gynecologic surgery and is considered a useful method for facilitation of ureteric identification and dissection during deep endometri…

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 …

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…

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…

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 objectiveTo investigate the short-term outcomes of laparoscopic ureteroneocystostomy in patients with ureteral endometriosis (UE).DesignRetrospective cohort study of consecutive patients who underwent surgery for the ureter endometrio…

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 …

ObjectiveTo 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).DesignStepwise demonstration of this method…

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…

ObjectiveTo show technical highlights of a nerve-sparing laparoscopic eradication of deep endometriosis (DE) with posterior compartment peritonectomy.DesignDemonstration of the technique with narrated video footage.SettingAn urban general h…

ObjectiveTo 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 designThis retrospective…
