Abstract: Objective：To evaluate the feasibility of the hysteroscopic resection of symptomatic type 3 myoma and the reproductive outcome after operation. Methods: Fifty-nine patients with type 3 myoma (＞25 mm, single) who underwent an hysteroscopic resection from January 2013 to October 2017 in Fuxing hospital were enrolled. The following medical data were recorded: symptoms, size of the type 3 myoma, preoperative treatment with GnRH analogue and length of surgery. The distance between the edge of myoma and the serosal layer before surgery and the thickness of the uterine wall of myoma side after hysteroscopic myomectomy were measured immediately. In the one month and three months after operation, the hysteroscopic reexamination was performed for the patients who had childbirth plan, and the symptomatic reexamination was for the patients without birth demand. The postoperative menstrual condition and pregnancy outcome were followed up for 12 months by the telephone follow-up. Results: The patient age was 37.1±4.8 (26-46) years. The surgical time was 49.4±16.4（20-105）min, and there was no surgical complication. The one-step hysteroscopic myomectomy was performed for 53 cases (89.8%), and the volume of  blood loss was 10(10，20) (5-200) mL. The distance between the edge of myoma and the serosal layer before surgery was 3.3±1.1 (1-5.7) mm, and the thickness of the uterine wall of myoma side immediately after hysteroscopic myomectomy was 8.9±1.3 (4.9-11.3) mm. The improvement rate of postoperative menstruation was 100%, and the postoperative pregnancy rate was 73.3%(11/15). Conclusions: Hysteroscopic resection for type 3 myoma under ultrasound guidance is safe as a potential alternative to traditional surgery. The postoperative reproductive outcome is good if it is performed by an experienced surgeon.
