During the establishment of pregnancy, extravillous trophoblast (EVT) must invade into the uterine decidua to facilitate decidual artery remodelling to create the placental blood supply. The local decidual environment is thought to regulate trophoblast invasion, however these interactions are poorly defined in humans. Recent evidence in women suggests impaired decidualization is associated with miscarriage and preeclampsia. Primary human endometrial stromal cells (HESC) and first trimester extravillous trophoblast (EVTs) were used to assess the effect of EVT-secreted factors on HESC decidualization, adhesion, proliferation and migration...

PURPOSE: Uterine myomas are the main cause of benign uterine diseases in premenopausal women. Objective of the present paper is to investigate the current best treatment modalities of myomas, depending on age of the patient and her desire to preserve fertility, as well as on clinical presentation of this pathology, such as size, number, and location of fibroids and, furthermore, on surgical experience of the gynecologist. METHODS: The design of our work is a systematic literature review of existing studies, reviews, and meta-analysis conducted in PubMed and Cochrane Library to identify relevant literature...

BACKGROUND: Gynecologic surgeries are performed through abdominal, vaginal, laparoscopic, or robot-assisted laparoscopic routes. However, if the pelvis is not accessible by one of these routes, there are no published reports to guide pelvic surgeons. CASE: A 34-year-old conjoined twin status postseparation with uterine didelphys and absence of her left colon and sacrum underwent hemihysterectomy, at which time her müllerian anomaly was unknown. She re-presented with vaginal bleeding and pain eventually attributed to a retained uterine horn...

We report a case of urinary bladder perforation during colonoscopy. A 67-year-old female, who had undergone a transabdominal hysterectomy for uterine myomas 15 years ago, visited the emergency department with complaint of abdominal pain after a screening colonoscopy. Laparoscopic examination revealed severe adhesion between the sigmoid colon and the urinary bladder. The urinary bladder wall was weakened, and several perforation sites were found. The surgery was converted to a laparotomy. After a thorough examination, we performed primary repair for the perforation sites, followed by an omentopexy...

Patients affected by the presence of leiomyomas may incur a substantial physical, emotional, social and financial toll as well as losses in their quality of life. Although many myomas are not amenable to medical therapy or hysteroscopic resection, many others are amenable to minimally invasive surgical approaches. In patients who prefer to retain their fertility, laparoscopic myomectomy should be considered the intervention of choice. In this review we expand on the surgical techniques of both conventional laparoscopic and robotic-assisted myomectomies...

BACKGROUND: The American Congress of Obstetricians and Gynecologists recommends that "the surgeon and patient discuss the potential benefits of the removal of the fallopian tubes during a hysterectomy in women at population risk of ovarian cancer who are not having an oophorectomy," resulting in an increasing rate of salpingectomy at the time of hysterectomy. Rates of salpingectomy are highest for laparoscopic and lowest for vaginal hysterectomy. OBJECTIVE: The primary objective of this study was to determine the feasibility of bilateral salpingectomy at the time of vaginal hysterectomy...

Glycosylation of uterine endometrial cells plays important roles to determine their receptive function to blastocysts. Trophoblast-derived pregnancy-associated plasma protein A (PAPPA) is specifically elevated in pregnant women serum, and is known to promote trophoblast cell proliferation and adhesion. However, the relationship between PAPPA and endometrium receptivity, as well as the regulation of N-fucosylation remains unclear. We found that rhPAPPA and PAPPA in the serum samples from pregnant women or conditioned medium of trophoblast cells promoted endometrium receptivity in vitro...

The uterine luminal epithelium is the first site of contact between fetal and maternal tissues during therian pregnancy and must undergo specialised changes for implantation of the blastocyst to be successful. These changes, collectively termed the plasma membrane transformation (PMT), allow the blastocyst to attach to the uterine epithelium preceding the formation of a placenta. There are similarities in the morphological and molecular changes occurring in live-bearing eutherian species during the PMT studied so far...

OBJECTIVE: Current uterine monitoring techniques have major drawbacks that could be avoided when using electrohysterography for uterine monitoring. Recently, a new electrohysterography method has been developed, providing a real-time tocogram on standard cardiotocography monitors. The diagnostic characteristics of this novel method need to be determined and compared to conventional methods We hypothesised that electrohysterography can perform better than external tocodynamometry due to the adhesive properties of the contact electrodes (less motion sensitive), and the improved signal acquisition through subcutaneous tissue (less obesity sensitive)...

OBJECTIVES: In vitro studies showed that lipophilic statins inhibit cell growth, adhesion, and invasion and induce apoptosis in cancer cell lines. In uterine cervical cancer, several important factors including age, stage, anemia, lymphovascular invasion, lymph node metastases, and parametrial spread were known to significantly predict survival. We investigated whether statin therapy as a prognostic factor would significantly predict survival in cervical cancer. METHODS: Patients with stages IB to IV cervical cancer who received radical hysterectomy and/or para-aortic lymph node dissection were included...

The success of implantation is an interactive process between the blastocyst and the uterus. Synchronized development of embryos with uterine differentiation to a receptive state is necessary to complete pregnancy. The period of uterine receptivity for implantation is limited and referred to as the "implantation window", which is regulated by ovarian steroid hormones. Implantation process is complicated due to the many signaling molecules in the hierarchical mechanisms with the embryo-uterine dialogue. The mouse is widely used in animal research, and is uniquely suited for reproductive studies, i...

Porcine conceptuses secrete pregnancy-recognition signals (estrogens, including estradiol-17β) that inhibit luteolysis, thereby prolonging progesterone production by corpora lutea. The supportive mechanism by which the conceptus also inhibits luteolysis is by shifting endometrial prostaglandin (PG) synthesis to luteoprotective PGE2. Progesterone stimulates endometrial production of factors that are essential for conceptus development. Priming the uterus by progesterone and loss of progesterone receptors from the uterine epithelium by D1ay 10-12 after estrus are key for achieving endometrial receptivity for implantation...

We present a rare asymptomatic case in which intestinal adhesions covered and occluded a site of uterine rupture, which was found during cesarean section. The patient had undergone laparoscopic myomectomy 5 years previously. However, detailed antenatal ultrasound and magnetic resonance imaging examinations revealed no uterine or placental abnormalities. It is thought that uterine rupture was not detected due to intestinal adhesions, which had occurred following the previous surgery. The present case suggests that women who conceive after laparoscopic myomectomy may be at risk of silent uterine rupture...

OBJECTIVES: To explore the clinical value of resection of bilateral fallopian tubes in patients with benign uterine diseases who received (laparoscopic) hysterectomy or subhysterectomy through the postoperative pathologic analysis of resected fallopian tubes. METHODS: A retrospective analysis was conducted to review the histopathological examination results in 1 272 women who underwent (laparoscopic) total hysterectomy or subtotal hysterectomy and the removal of bilateral fallopian tube simultaneously due to uterine leiomyoma, adenomyosis and other benign lesions from December 2010 to December 2015...

Abdominal surgery is linked with peritoneal adhesions. We investigated that the anti-fibrotic agent pirfenidone (PFD) has immune modulating activities and evaluated its effects on the function of T helper type 1 (Th1), Th2 and T regulatory (Treg) cells, which may play important roles in peritoneal adhesions. Eighteen female Wistar rats underwent right-sided parietal peritoneal and right uterine horn adhesion model. Rats were randomized into 3 groups as group 1 (control) (closure of midline abdominal incision without any agent administrations), group 2 (closure of incision after intraperitoneal administration of PFD) and group 3 (closure of incision and only oral administration of PFD for 14 days)...
