To investigate the artificial vaginal microecological features in patients who underwent laparoscopic peritoneal vaginoplasty. 54 cases of patients with artificial vagina after laparoscopic peritoneal vaginoplasty were included in this study. Microecosystem evaluation was performed. Artificial vaginal functional tests and biopsy from vaginal walls were performed. After laparoscopic peritoneal vaginoplasty, the artificial vaginal flora intensity was level II∼III (88.9%); the vaginal flora diversity was level II∼III (72.2%); the predominant vaginal bacteria were gram-positive macrobacillus (27.8%); approximately 57.4% of the patients had vaginal pH ≤ 4.5; there was no pathogenic bateria or other pathogens; dysbiosis accounted for 53.7% of the patients (64.5% of the patients who had the vaginoplasty operation less than 2 years ago exhibited dysbiosis; 39.1% of the patients who had the operation at least 2 years ago exhibited dysbiosis). Vaginal dysbiosis is common after laparoscopic peritoneal vaginoplasty. However, as time goes by, the artificial vaginal microecological condition gradually becomes normal. Evaluation of vaginal microenvironment after laparoscopic peritoneal vaginoplasty might play an important role in reproductive tract infection prevention and neovagina health care.
