Intrauterine Adhesion Rate After Hysteroscopic Myomectomy and Application of HYALOBARRIER Gel (HYGEM)

Brief Summary:
The purpose of this study is to evaluate the intrauterine adhesion rate after the application of HYALOBARRIER Gel at the end of hysteroscopic myomectomy. Secondary endpoints were tolerance and side effect and subsequent fertility.

Condition or disease Intervention/treatment Phase
Myoma Device: HYALOBARRIER Gel Not Applicable

Detailed Description:
Hysteroscopic myomectomy is the referent surgical treatment for submucous myoma. But intrauterine adhesion rate was evaluated about 7 to 15% after this procedure. The investigators hypothetically believe that application of HYALOBARRIER Gel at the end of the procedure, could be reduce the mean intrauterine rate to 50%. Thus, the investigators performed a multicenter (n = 20) prospective study non randomized in 220 patients with submucous myoma < 3 cm of diameter, evaluated by preoperative ultrasound. The investigators prefer this study design, because the principal reason is the number of enrolled patient were more 200 patients in each group with a double blind randomized study. Now, in all patients, after hysteroscopic myomectomy which performed with a same technique in each center (bipolar coagulation and physiologic serum), a diagnostic hysteroscopy was performed at 2 month to determinate the existence of intrauterine adhesion. Secondary end points were in this study the tolerance and side effects of HYALOBARRIER Gel and the subsequent fertility at 2 years.

For each patient, the HYALOBARRIER Gel was introduced into the uterine cavity with the canula after hysteroscopic myomectomy procedure

Primary Outcome Measures :
  1. The formation of postsurgical uterine synechiae rate with HyalobarrierR Gel Endo in hysteroscopic myomectomy [ Time Frame: between 4 and 8 weeks after initial hysteroscopic myomectomy ]

Secondary Outcome Measures :
  1. the number of participants with adverse events as a measure of safety and tolerability during the time of the study [ Time Frame: 2 years ]
  2. Postsurgical fertility with evaluation of number of participants who became pregnant after surgery, spontaneously and/or after assisted reproductive technologies [ Time Frame: 2 years ]
