Excising the neovagina due to introital atresia and closed neovaginal loop after sigmoid vaginoplasty: A case report

INTRODUCTION: Vaginal agenesis is a congenital disorder, which can be managed by nonsurgical dilation or surgical reconstruction of the vagina. The sigmoid vaginoplasty procedure is a popular approach, which pulls down part of the sigmoid colon to form a neovagina. One complication of this procedure is introital stenosis. PATIENT CONCERNS: A 55-year-old woman presented to the outpatient general surgery department with severe, persistent abdominal pain. The patient was diagnosed with congenital absence of uterus and vagina, and a sigmoid vaginoplasty was performed 34 years ago. DIAGNOSIS: A pelvic MRI and an abdominal enhanced CT scan were performed, finding that the uterus was absent, and the os of the vagina was closed, forming a closed loop full of fluid. Introital atresia and closed loop of neovaginal colon conduit were diagnosed. INTERVENTIONS: Based on our conclusions and the patient's consent we surgically removed the neovagina. OUTCOMES: After surgery, the abdominal pain was relieved, and the patient reported full recovery during a 6-month follow-up appointment. CONCLUSION: Introital stenosis is one of the long-term complications of sigmoid vaginoplasty procedure. Introital stenosis, leading to introital atresia, is rare but may occur. Surgical removal of neovagina can relieve the pain in patients who do not have the demand of sexual intercourse.
