A self-developed contained bag for laparoscopic myomectomy morcellation.

Objectives: Open power morcellation during a laparoscopic myomectomy (LM) can result in the dissemination of benign or occult malignant tumor cells in the abdominopelvic cavity. The development of a new contained collection bag for power morcellation is now favored by gynecologic surgeons worldwide.

Material And Methods: This study was a single-arm trial comprising 20 women who consecutively underwent an LM involving the use of a newly designed contained collection bag for power morcellation between November 3rd 2017 and April 31st 2018.

Effect of vasopressin injection technique in laparoscopic excision of bilateral ovarian endometriomas on ovarian reserve: prospective randomized study.

Study Objective: To evaluate the effects of vasopressin injection technique in laparoscopic cystectomy on ovarian reserve in patients with bilateral endometriomas.

Design: Randomized prospective study (Canadian Task Force classification I).

Setting: University hospital.

Vascular endothelial growth factor expression up-regulated by endometrial ischemia in secretory phase plays an important role in endometriosis.

Primary human endometrial cells were exposed to hypoxia preconditioning (HPC), HPC-hypoxia, and hypoxia conditions, and then endometrial tissue treated with ischemia preconditioning (IPC) was transplanted onto the chick embryo chorioallantoic membrane to investigate the role of slight ischemia of endometrium in the pathologic process of endometriosis. IPC up-regulated vascular endothelial growth factor expression and decreased apoptosis of endometrial cells, thus facilitating the endometrial fragments' ectopic implantation.
