Background: The aim of this study was to verify the efficacy of sodium-2-mercaptoethanesulfonate (mesna) in the chemical separation of tissues in abdominal myomectomies when used with the traditional mechanical separation techniques. Study Design: In a prospective, randomized study, 58 women underwent abdominal myomectomy. In 29 of these, we used mesna for highlighting and separating tissues, and in the other 29 we used saline solution for the same purposes. The variables evaluated included the number of myomas removed, the volume of the biggest myoma, and the total volume of the myomas removed in every intervention. We also recorded operating time, the length of hospital stay, the degree of procedure difficulty, perioperative blood loss, operative complications, and cost. Results: The operation was significantly shorter in the mesna group (p < 0.05) even though the volume and the number of myomas were larger. The degree of difficulty evaluated by the surgeon at the end of every operation was not significantly different in the two groups. The reduction in hemoglobin 24 hours after operation was significantly less in the patients treated with mesna (p = 0.006), but this difference was probably altered by the increase in hematocrit levels. Conclusions: Because of its ability as a chemical dissector, mesna may be a useful aid in this type of benign gynecologic operation. Larger studies to confirm this are needed.
