Development and evaluation of an improved laparoscopic myomectomy adopting intracapsular rotary-cut procedures.

Objectives: To develop and evaluate the efficacy and feasibility of Intracapsular Rotary-cut Procedure (IRCP) in laparoscopic myomectomy (LM).

Study Design: It is a retrospective study conducted in Peking University Shenzhen Hospital (PUSH) in Shenzhen, China. A total of 96 patients who were treated with LM because of big and moderate size of myomas in PUSH from January 2013 and December 2015 were enrolled in this study.

[Clinical features of abnormal chromosome karyotypes in twin pregnancies complicated with structural abnormalities].

Objective: To investigate the clinical features of the abnormal chromosome karyotypes in twin pregnancies complicated with fetal malformations.

Methods: Totally 181 twin pregnancies (362 fetuses) in which one or two fetuses had abnormalities diagnosed by ultrasound were referred to the First Affiliated Hospital of Sun Yat-Sen University from January, 2000 to September, 2010. They were divided into different groups according to (1) maternal age: the cases with maternal age ≥ 35 were divided into advanced pregnancy group (105 fetuses), and those with maternal age < 35 were divided into young pregnancy group (203 fetuses); (2) conceived method: those conceived by assisted reproductive technology were divided into assisted reproductive group (81 fetuses), and the natural conception pregnancies were divided into natural conception group (227 fetuses); (3) chorionicity: the monochorionic twin (MCT) pregnancies were divided into MCT group (123 fetuses), and the dichorionic twin (DCT) pregnancies were divided into DCT group (185 fetuses); (4) structural abnormalities: 205 fetuses with structural abnormalities were divided into the abnormal fetal group, and 103 fetuses without structural abnormalities were divided into the normal fetal group.
