The learning curve of laparoscopic single-site salpingectomy with conventional laparoscopic instruments: A retrospective cohort study.

Tubal pregnancy is a common cause of maternal mortality in early pregnancy. Transumbilical laparoendoscopic single-site surgery (TU-LESS) has gained popularity due to its safety and aesthetic advantages. However, the lack of affordable disposable entry platforms hinders its widespread adoption.

Hysteroscopic suture of levonorgestrel-releasing intrauterine system: learning curve for in vitro simulation training.

Objective: To simulate hysteroscopic suturing in vitro and analyze the learning curve of gynecologists with different experience levels.

Methods: Three gynecologists were trained on uterine models in a circulating water box. The posterior uterine wall was sutured 10 times under hysteroscopy for 5 consecutive days, and the time of each suture procedure was recorded.

Rare case of endometrial vascular dystrophy: Three case reports.

Rationale: Endometrial vascular dystrophy refers to abnormal vessels that are very tortuous, dilated, and sometimes thrombosed. Endometrial vascular dystrophy is rare under hysteroscopy.

Patient: All three patients had a history of abnormal uterine bleeding.

Complete androgen insensitivity syndrome: a case report and literature review.

Complete androgen insensitivity syndrome (CAIS) is a rare disease that can be easily misdiagnosed. Before puberty, this condition is easily misdiagnosed as an inguinal hernia. This case report describes a 31-year-old phenotypically female patient with CAIS who was misdiagnosed twice previously with an inguinal hernia.

[Association between hypertensive left ventricular hypertrophy and cardiovascular events in adult Beijing residents: a cohort study].

Objective: To analyze the impact of hypertensive left ventricular hypertrophy (LVH) on cardiovascular events (CVD) in adult Beijing residents.

Methods: CVD risk factor survey was conducted in 7023 Beijing residents aged 25 - 64 by a stratified-random sample design from 1984 to 1993 in three years interval. CVD events were followed up and the association of the hypertensive LVH and risk of CVD and total death was analyzed by multivariable Cox Regression Model.
