Suspected Incipient Cervical Endometriosis at the Hematocolpos-Ectocervix Interface in an Adolescent With OHVIRA
Journal of minimally invasive gynecology ·doi:10.1016/j.jmig.2025.12.014
case-report 2024
A case of a blind-ending right ureter first identified intraoperatively during total laparoscopic hysterectomy for uterine adenomyosis and fibroids in a woman with severe ipsilateral kidney hypoplasia
Journal of Obstetrics and Gynaecology Research ·doi:10.1111/jog.15992

Detecting ureteral injury-a serious intraoperative and postoperative complication of hysterectomy-is a high level of difficulty if ureteral malformations are not identified preoperatively. A 39-year-old Japanese woman underwent total laparo…

Case Report: The first case of successful pregnancy and live birth following laparoscopic resection of adenomyosis under real-time intraoperative ultrasound elastography guidance
Frontiers in medicine ·doi:10.3389/fmed.2024.1457611

OBJECTIVE: Adenomyosis-related infertility is increasingly being diagnosed, and surgical intervention has been suggested to improve fertility. Elastography, a noninvasive ultrasound technique, is promising for diagnosing and guiding the res…

"Pure" robot simple hysterectomy with four arms and no uterine manipulator: a retrospective, non-blind, and non-randomized, comparative study
·doi:10.21203/rs.3.rs-4418722/v1

Abstract Nearly 20 years have passed since the introduction of robotic surgery for total hysterectomy, and its development has accelerated. However, its advantages over laparoscopic and open surgeries remain unclear, especially since some i…

Laparoscopic Adenomyomectomy under Real-Time Intraoperative Ultrasound Elastography Guidance: A Case Series and Feasibility Study
Journal of clinical medicine ·doi:10.3390/jcm11226707

BACKGROUND: This study aimed to examine the clinical characteristics of 11 patients undergoing laparoscopic adenomyomectomy guided by intraoperative ultrasound elastography and this technique's feasibility. PATIENTS AND METHODS: Eleven pat…

A Case of Elastography-Assisted Laparoscopic Fertility Preservation for Severe Deep Endometriosis Causing Ureteral Stenosis and Subtype II Adenomyosis
·doi:10.3390/endocrines2030032

Adenomyosis is commonly treated by total hysterectomy. Adenomyomectomy is considered for women of reproductive age who wish to preserve their fertility. However, a high recurrence rate following adenomyomectomy has been reported because com…

A Feasible Technique in Laparoscopic Excision for Juvenile Cystic Adenomyosis: A Case Report, Literature Review, and Surgical Video
·doi:10.3390/endocrines2030026

Background: Juvenile cystic adenomyosis (JCA) is a rare uterine lesion. We present the case of a young woman who was diagnosed with JCA and subsequently managed with laparoscopic cyst removal with sharp and blunt dissection. Moreover, we pr…

New surgical technique of laparoscopic resection of adenomyosis under real-time intraoperative ultrasound elastography guidance: A case report
Heliyon ·doi:10.1016/j.heliyon.2020.e04628

Detecting adenomyosis in the myometrium is a challenge since it is infiltrative with ill-defined margins and can be often confused with uterine fibroids. However, recent advances, such as ultrasound elastography, have enabled its detection …

Primary endometrioid carcinoma of the uterosacral ligament arising from deep infiltrating endometriosis 6 years after bilateral salpingo-oophorectomy due to atypical proliferative endometrioid tumor of the ovary: a rare case report
World journal of surgical oncology ·doi:10.1186/s12957-020-02105-1

Abstract Background Endometriosis can potentially lead to the development of a malignant tumor. Most malignant tumors arising from the endometriosis originate from the ovarian endometrioma, whereas those arising from extragonadal lesions ar…

Combination of microwave endometrial ablation and postoperative dienogest administration is effective for treating symptomatic adenomyosis
Journal of Obstetrics and Gynaecology Research ·doi:10.1111/jog.13720

AIM: Menorrhagia and dysmenorrhea are common symptoms. Uterine adenomyosis is one of the causes of menorrhagia and dysmenorrhea. These symptoms often decrease the quality of life in women. Microwave endometrial ablation (MEA) is a recently …

Ureteral stenosis due to DIE (deep infiltrating endometriosis) with difficulty in treatment: Case report and brief literature review
Gynecology and minimally invasive therapy ·doi:10.1016/j.gmit.2017.06.007

Ureteral involvement is rare, with an estimated frequency of 10-14% in cases of deep infiltrating endometriosis. An important complication of ureteral involvement is asymptomatic loss of renal function. We reported that a 49-year-oId woman …
