[Clinical analysis on 28 cases of oblique vaginal septum syndrome]

To sum up the diagnosis and surgical treatment of oblique vaginal septum syndrome (OVSS).

The clinical data of OVSS patients from January 2005 to June 2010 were retrospectively analyzed. The patients were divided into 2 groups: a re-operation group (n=11)and a first-operation group (n=17).The general clinical data, surgery Methods and outcome between 2 groups were compared.

The number of patients with pelvic mass on first attendance in the re-operation group was significantly more than those in the first-operation group(χ(2)=8.134,P=0.004). Only 1 patient was diagnosed during the first operation in the re-operation group. All the patients were diagnosed with OVSS in the first-operation group. Except for 1 case of hysterectomy in the post-cavity of the septum in each group, the basic operation was oblique vaginal septum resection. All the patients were followed up. Symptoms as the pelvic mass, irregular vaginal bleeding, and vaginal flow of purulence completely disappeared, and dysmenorrhea symptoms completely disappeared or apparently improved.

The diversity of clinical manifestations of OVSS increases the difficulty of diagnosis and treatment. In younger patients with pelvic mass,primary dysmenorrheal, and one side renal agenesis, OVSS should be highly suspected. The basic treatment for OVSS is septum resection and drainage, and the correct pre-operative diagnosis is critical. If necessary, combination of hysteroscopy with laparoscopy will be helpful.
