This study evaluates the feasibility, safety, and efficiency of transvaginal in-bag electromechanical morcellation for specimen extraction in patients undergoing total laparoscopic hysterectomy for large uteri.
This single-center prospective study investigates a novel transvaginal specimen extraction technique using a sealed containment bag combined with electromechanical morcellation. The procedure aims to improve specimen extraction efficiency while preventing tissue dissemination during laparoscopic hysterectomy for uteri larger than 12-week gestational size.
