Second-generation endometrial ablation technologies: the hot liquid balloons

Thermal balloon ablation versus laparoscopic supracervical hysterectomy for the surgical treatment of heavy menstrual bleeding: A randomized study

“…Some less invasive surgical techniques have been developed with the purpose of removing the entire thickness of the endometrium. Second generation endometrial ablation systems (microwave ablation and thermal balloon ablation) have been shown to significantly reduce menstrual blood loss 4–6 . However, these less invasive surgical techniques are not always entirely successful, and additional surgical treatment is often required.…”

Treatment options for dysfunctional uterine bleeding: evaluation of clinical results

“…Its application results seem slightly improved compared to Thermachoice® in nonrandomized studies (satisfaction rate varying between 91% and 96%, amenorrhea rate ranging between 15% and 68%, overall success rate of 92-98% and failure rate up to 7%) [55]. There are few randomized trials comparing Cavaterm® with first-and second-generation ablative techniques, showing no evidence of significant differences in the rates of amenorrhea at any follow-up time, from 6 months to 5 years after surgery [54].…”

“…Thermachoice® was the first of the second-generation ablation technique, and its effectiveness has been evaluated intensively. After the application of Thermachoice®, a satisfaction rate is reported to be up to 90%, while the amenorrhea rate was up to 20% 1 year following treatment [55]. Following clinical evaluation of Thermachoice®, improved devices were introduced in 1998 (Thermachoice® II) and 2004 (Thermachoice® III).…”

Ablación endometrial: Tipos, técnicas y evidencias de su utilidad. revisión de la literatura

“…La unidad controladora se activa y de este modo el fluido (5% de dextrosa en agua) se calienta después de inyectarse en el globo y utiliza microcircuitos para controlar los parámetros de presión, la temperatura del fluido y automatización durante el tratamiento. 3,7,33 En los tres sistemas el ciclo se inicia cuando la temperatura alcanza 87 0 C y la presión está entre 160 y 180 mm de Hg. La duración del tratamiento es alrededor de ocho minutos.…”

“…Debido a que los resultados clínicos mejoran si se reduce al mínimo el espesor del endometrio, el fabricante recomienda que las pacientes o bien sean tratadas con legrado intraoperatorio o se sometan a la supresión médica previa al procedimiento con esteroides gonadales o análogos de GnRH. 3,7,14,33 El ensayo clínico con el que recibió aprobación de la FDA informó sobre los resultados a los doce meses del procedimiento en 255 mujeres manejadas con ablación endometrial con TC o con rollerball. Se excluyeron las paciente con miomas submucosos, cavidades uterinas grandes (>30 ml en el volumen o histerometría >10 cm), pequeñas cavidades uterinas (<2 ml de volumen o histerometría <6 cm), o ablación endometrial previa.…”
