title: Congenital Atresia of Uterine Isthmus: Successful Diagnosis and End-To-End Anastomosis.
abstract: BACKGROUND
  Müllerian duct anomalies are rare and occasionally diagnosed in adolescents with primary amenorrhea, abdominal pain, and sexual difficulties. They are present in a variety of forms and sometimes difficult to appropriately classify. The management of malformations remains controversial.
  
  
  METHODS
  A 15-year-old girl with primary amenorrhea and cyclic lower abdominal pain was found on laparoscopic examination to have an asymmetric ball-shaped uterus with isthmus stenosis suspended in the pelvis. The junction between the lower segment of uterus and the cervix was very thin and stenotic with scar-like tissue changes. Combined with pathologic evaluation, it was finally diagnosed as congenital atresia of uterine isthmus. Thus, an end-to-end anastomosis was performed instead of surgical resection.
  
  
  CONCLUSIONS
  Müllerian duct anomalies in a variety of forms can be difficult to diagnosis correctly and treat appropriately. Preservation of reproductive ability is the first objective of all treatments.
