Introduction
For women with congenital vaginal agenesis and sexual needs, creating a functioning neovagina is a practical therapeutic schedule, and different methods have been reported in the literature. Nowadays, non-operative vaginal dilation is the preferred treatment proposed by the American Society of Obstetrics and Gynecology[1]. Besides, tissues such as peritoneum and intestinal segments were frequently used for colpoplasty, especially the sigmoid colon. In the early 1980s, colpopoiesis using the sigmoid intestine was first reported by Goligher[2]. The advantages of this tissue include efficient blood supply and self-lubrication, and regular vaginal dilation is not required. In a meta-analysis, Horbach reported that the overall rate was about 6.4% [3]. However, although the rate is lower than other treatment, it is also associated with various postoperative complications, including postoperative ileus, ulcerative colitis and adenocarcinoma of neovagina[4]. Though the incidence of NP is relatively low (3-8%), it does bring great inconvenience to patients, and expose tough challenge to the gynecologists, for there is no accordant and standard repair solution presented up to now[5]. Hereon, we report a case of NP 10 years after sigmoid colon vaginoplasty that was successfully repaired by laparoscopic sacro-colpopexy with a mesh, hoping to provide meaningful evidence for this rare situation.
