Objective: To investigate the efficiency and factors related to the recurrence of transcervical resection of endometrium (TCRE) in treating women with dysfunctional uterine bleeding (DUB).
Methods: Two hundred and twenty women with DUB were selected for TCRE. Specimens from removed endometrium were obtained during the procedures and their menstruation and menorrhagia after the operations were followed up. We also studied the uterine specimens obtained from the recurrent cases undergoing hysterectomies. The specimens were stained by hematoxylin-eosin and immuno-histochemistry respectively to evaluate the depth of removed myometrium and the histopathologic changes in relapsed cases.
Results: The follow up period after operation was 24 to 114 months. (1) Overall effective rate was 94.5%, in which amenorrhea rate was 25.9%, menstruation reduction rate was 68.6%. (2) The effective rate of corrective anemia was 97.3% and the satisfaction rate for the operation was 92.3%. (3) Thirty-eight cases required subsequent treatment as a result of recurrence, of which 10 cases underwent hysterectomy and 3 cases underwent repeat TCRE and 25 cases were given medicine treatment. (4) The average depth of myometrium in removed endometrium strip was 2.12 approximately 3.26 mm. (5) Endometrium regrowth was seen in the resected uterine specimens from relapsed cases and adenomyosis was also found in the intra-uterine wall in some cases.
Conclusions: (1) TCRE is a safe and effective alternative treatment for DUB. (2) The main factor reducing the efficiency is either incomplete removal of endometrium or adenomyosis. (3) Standardizing the procedures and strengthening postoperative management are essential requirements for improving the efficiency of TCRE.

Background: The neck, and specifically the prominence of the thyroid cartilage, can be considered a marker of male gender, which is often unwanted by transgender women. Chondrolaryngoplasty is traditionally performed using an open transcervical approach, which, while effective, leaves visible scars that can compromise patient satisfaction. Recent advancements, such as the transoral endoscopic vestibular approach (TOEVA), have emerged as promising alternatives, eliminating external scars and improving esthetic outcomes.

Uterine fibroids are benign monoclonal neoplasms of the myometrium, representing the most common female pelvic neoplasms globally. Treatments may be invasive, such as hysterectomy and myomectomy, non-invasive, such as medical therapy or focused ultrasound, or minimally invasive, such as transcervical radiofrequency ablation (TFA). To date, more than 12,000 women have been treated worldwide using TFA with the Sonata System.

In the part I, we have already reported the rationale, efficacy, complication, and limitation of using transcervical resection of myoma (TCRM) in the management of women with symptomatic uterine fibroids, particularly for those belonging to the International Federation of Gynaecology & Obstetrics (FIGO) myoma classification system as FIGO types 0-2. The current review as part II, the discussion will focus on the techniques, tips and complication prevention or management when TCRM is applied in the management of women with symptomatic submucosal myoma. With better understanding for TCRM-related basic knowledge, such as rationale, efficacy, complication, technique review, tips and prevention or management of complications, plus the well-training and carefully performing TCRM through preceding accurate diagnosis, and good and careful preparation and intensive monitoring during operation and using effective strategy to preventing short-term and long-term complications, TCRM can become one of most powerful strategies in offering the less traumatic injury to the uterus, and an effective and safe surgical approach in dealing with women with symptomatic submucosal myoma.

Uterine fibroids occur frequently in women during the reproductive age, and they are rarely associated with clinical meaning because of their benign characteristics and asymptomatic clinical presentation. Sometimes, uterine fibroids are symptomatic and associated with compression syndrome, infertility, chronic pelvic pain and heavy menstrual bleeding. All need further intervention and treatment.
