A Case of Early-Stage Lower Uterine Segment Carcinoma With Hysteroscopic Observation of Visual Changes Induced by a Gonadotropin-Releasing Hormone (GnRH) Antagonist.

Endometrial carcinomas in the isthmus are called lower uterine segment (LUS) cancers. It is a rare location among uterine cancers and is known to be associated with Lynch syndrome, which tends to occur at a young age. Preoperative diagnosis may be difficult due to its anatomical location, and the prognosis is poorer than that of uterine cancer in general.

Long-term conservative management of symptomatic bladder endometriosis: A case series of 17 patients.

Objectives: This study aimed to evaluate the course of long-term conservative management of bladder endometriosis (BE).

Materials And Methods: We retrospectively reviewed 17 cases of BE conservatively managed without surgery in our facility. The following factors were analyzed: age, medical history, lesion size, symptoms, hormonal treatment, and follow-up outcomes.

Elevated phosphorylation of estrogen receptor α at serine-118 in ovarian endometrioma.

Objective: To evaluate the phosphorylation of estrogen receptor α at serine-118 (phospho-ERα S118) in the endometrium, ovarian endometrioma, and deep infiltrating endometriosis (DIE).

Design: Experimental study.

Setting: University-affiliated hospital and academic research laboratory.

A survey of public attitudes toward uterus transplantation, surrogacy, and adoption in Japan.

This study aimed to evaluate the attitudes of male and female members of the public toward uterus transplantation (UTx), surrogacy, and adoption in Japan via a web-based survey. One thousand six hundred participants were recruited with equal segregation of age (20s, 30s, 40s, and 50s) and gender. We assessed the association between ethical view and gender, age, infertility, and the knowledge level of UTx, using a questionnaire.

Clinical aspects and management of inguinal endometriosis: A case series of 20 patients.

Aim: This study aimed to describe the clinical presentation, diagnostic evaluation, and operative or medical management of inguinal endometriosis.

Methods: In this study, we retrospectively reviewed 20 cases of inguinal endometriosis in our facility, particularly on the clinical characteristics, diagnosis, and surgical and medical treatment.

Results: We retrospectively investigated the following items for each patient: age at diagnosis, surgical history, presence of extragenital endometriosis, symptoms, imaging modalities, surgical therapy, hormonal therapy, follow-up period, postoperative recurrence and time to recurrence.

Contralateral ovarian endometrioma recurrence after unilateral salpingo-oophorectomy.

Background: The recurrence rate after unilateral salpingo-oophorectomy (USO) for unilateral endometrioma has not been reported. We evaluated the rate of and risk factors for endometrioma recurrence after USO.

Methods: In this retrospective observational study, we enrolled 110 women (age, 35-45 years) who underwent laparoscopic USO (n = 50) or cystectomy (n = 60) for unilateral ovarian endometrioma from January 2010 through December 2012.

Gynecologists May Underestimate the Amount of Blood Loss during Total Laparoscopic Hysterectomy.

Background: We considered the possibility of underestimation of the amount of bleeding during laparoscopic surgery, and we investigated comparing the amount of bleeding between laparoscopic surgery and open surgery by considering the concentration of hemoglobin before and after surgery as indicators.

Methods: The following procedures were included: A, surgery for ovarian tumor; B, myomectomy; and C, hysterectomy either by laparoscopic surgery or open surgery. Patients who underwent the above procedures in between January 1, 2010, and December 31, 2017, were enrolled.

Computer vision for total laparoscopic hysterectomy.

Introduction: Laparoscopic surgery is widely performed in various surgical fields, but this technique requires time for surgeons to master. However, at the same time, there are many advantages in visualizing the operative field through a camera. In other words, we can visualize what we cannot see with our own eyes by using augmented reality and computer vision.

Retained Barium in the Appendix Is Difficult to Distinguish from Surgical Remnants following Laparoscopic Surgery.

Surgical materials, such as gauze, can be accidentally left inside of patients following surgery. This iatrogenic complication should be avoided and is often prevented by routine X-ray analysis after surgical abdominal procedures. We report a case of retained barium in the appendix that was difficult to distinguish from surgical remnants.

Exploration of assistive technology for uniform laparoscopic surgery.

Introduction: Laparoscopic surgery is less invasive than open surgery and is now common in various medical fields. However, laparoscopic surgery is more difficult than open surgery and often requires additional time for the operator to achieve mastery. Therefore, we investigated the use of assistive technology for uniform laparoscopic surgery.
