However, there are limited systematic reviews and meta-analyses examining these associations.

A New Surgical Method of U-Shaped Myometrial Excavation and Modified Suture Approach with Uterus Preservation for Diffuse Adenomyosis.

Objective: To evaluate the feasibility, safety, and efficacy of a new surgical method of U-shaped myometrial excavation and modified suture approach with uterus preservation for diffuse adenomyosis.

Methods: From January 2012 to December 2014, 198 patients with diffuse adenomyosis were surgically treated using this novel procedure in Zhengzhou Hua-Shan Hospital. Degree of dysmenorrhea, menstrual blood volume, serum CA 125, and uterine size before and at 1 month, 3 months, 6 months, 12 months, and 24 months after surgery were compared.
