Laparoscopic cervico-isthmic anastomosis for old traumatic disjunction between the cervix and the uterine corpus: a case report and literature review

BACKGROUND: Old traumatic disjunction between the cervix and the uterine corpus is very rare case. In most cases, it is not immediately noticed until the onset of other symptoms, such as amenorrhea, periodic abdominal pain and so on. Scanty cases of anastomosis surgery via laparoscope have been reported. CASE PRESENTATION: We report here a 23-year-old young woman with the primary amenorrhea due to traumatic cervico-isthmic disjunction. The patient had a closed pelvic fracture at the age of 4 and has experienced periodic lower abdominal pain since the age of 17 years. A complete disjunction between the cervix and the uterine corpus was diagnosed. Laparoscopic cervico-isthmic anastomosis was performed to restore the continuity of the endometrial cavity and cervical canal. After this surgery, normal menstruation was resumed without cyclic abdominal pain. CONCLUSION: Laparoscopic cervico-isthmic anastomosis could reconstruct the uterine outflow tract successfully, alleviate symptoms, and achieve a good short-term outcome.
