Research on Laparoscopic Fertility-Sparing Surgery in Early-Stage Cervical Cancer

"The LAVRT procedure began with laparoscopic pelvic lymphadenectomy, and all lymph nodes were removed for frozen pathological analysis. The laparoscopic-assisted vaginal radical trachelectomy procedure was continued only if the nodes were negative. The pararectal pouch was revealed, and the uterine arteries were divided from their origin to the internal iliac artery. The ureters were freed from the posterior leaf of the broad ligament down to the level where they entered the ureteral tunnel and then displaced laterally. The uterosacral ligaments, cardinal ligaments, and parametrial portions were then divided and dissected. The section of the procedure was performed laparoscopically. The vaginal epithelium was circumferentially incised approximately 3 cm distal to the endocervix. Frozen section analysis confirmed no cancer involvement at the endocervical or vaginal margin. The vaginal mucosa was sutured to the cervical stump to form a new cervical os."
