AI Article Synopsis
- The study aimed to assess the accessibility and ability to evaluate the uterine cavity 12 months after cryoablation using the Cerene device, across multiple centers in the US, Canada, and Mexico.
- Out of 223 subjects who underwent diagnostic hysteroscopy, 98.7% had an accessible uterine cavity, and 92.7% of those had visible results, with a high percentage showing both tubal ostia.
- The findings indicate that in-office hysteroscopy is effective for evaluating the uterine cavity post-ablation, with minimal complications reported during the procedures.
Article Abstract
Study Objective: To evaluate whether physical access and the ability to systematically assess the postablation uterine cavity were preserved at 12 months after endometrial ablation with the Cerene cryotherapy device (ChannelMedsystems, Emeryville, CA).
Design: A prospective, multicenter, single-arm study.
Setting: In the clinic at 8 US sites and outpatient hospital setting at 2 sites in Canada and 1 site in Mexico.
Patients: A total of 230 (of 242) subjects continued in the study at the Month 12 visit after ablation. Two hundred twenty-three subjects were available for a diagnostic hysteroscopic evaluation.
Interventions: Subjects who had previously been treated with a 2.5-minute cryoablation of the endometrium utilizing the Cerene device underwent a diagnostic hysteroscopy at the Month 12 follow-up visit.
Measurements And Main Results: The uterine cavity was accessible in 220 of 223 subjects (98.7%) and not accessible in 3 (1.3%) because of pain (n = 2) and cervical stenosis (n = 1). Visualization of the uterine cavity was possible in 204 of 220 subjects (92.7%) with one or both tubal ostia identified in 89.2% (182 of 204) of subjects. Both tubal ostia were visible in 160 of 204 subjects (78.4%) and one ostium in 22 of 204 subjects (10.8%). The cavity was not visualized in the remaining 16 of 220 subjects (7.2%) because of intrauterine adhesions (n = 14), technical difficulties (n = 1), or menstruation (n = 1). In 95.6% (195 of 204) of subjects where the cavity was visualized, the hysteroscopic view was judged adequate to evaluate the uterine cavity for pathologic change. No significant complications occurred during the hysteroscopic evaluations.
Conclusion: This is the largest study to date conducted to hysteroscopically evaluate the postablation uterine cavity. Uterine cavity assessment with in-office hysteroscopy 1 year after the use of the Cerene cryotherapy device is attainable, enabling both diagnostic and therapeutic procedures within the endometrial cavity.

Unlabelled: Endometriosis is a chronic disease characterized by the growth of the endometrium outside the uterine cavity. In response to estradiol, this tissue begins to proliferate and grow, forming lesions and nodules, which can invade the tissues, causing pelvic pain and infertility. The most widely used pharmacological treatment is progesterone, which manages to reduce symptoms, but approximately one-third of patients develop resistance to treatment.

Some women infected with (CT) are asymptomatic, while others experience lower abdominal discomfort when the inflammatory process extends to the fallopian tubes. Without treatment, salpingitis can progress to pelvic peritonitis and subsequently, peritonitis in the upper abdomen, a condition known as Fitz-Hugh-Curtis syndrome, in some cases. A nucleic acid amplification assay is required for diagnosing CT infection.

Background: Epignathus is a rare kind of teratoma. Its estimated incidence is one in 35,000-200,000 live births, and it may cause high mortality by causing airway obstruction in the neonatal period. It is generally diagnosed in the prenatal period.

Background: A didelphic uterus represents a unique and infrequent congenital condition in which a woman possesses two distinct uteri, each with its own cervix. This anomaly arises due to partial or incomplete merging of the Müllerian ducts during the developmental stages in the womb. Accounting for uterine malformations, a didelphic uterus is a relatively rare condition, affecting approximately 0.

Early missed abortion is defined as a pregnancy of ≤ 12 weeks in which there is a cessation of life in the developing embryo or fetus, leading to its retention within the uterine cavity without being spontaneously expelled promptly. This condition is commonly observed and significantly impacts human reproductive health. This study aimed to identify key genes related to ferroptosis that could serve as novel biomarkers for early missed abortion.
