Background: Symptomatic Uterine leiomyomata may lead to many symptoms including abnormal uterine bleeding, mass pressure effects and infertility. Myomectomy is an option for conservative management, however, it is associated with some disadvantages, mainly increased intra-operative blood loss. Intra-myometrial vasopressin injection during myomectomy is an effective method to decrease the intraoperative bleeding due to its vasoconstrictor effect. Octreotide Acetate (OA) is another vasoconstrictor agent that have not been tested for gynaecologic indications. The current study was conducted to assess the efficacy of local injection of OA in reducing blood loss during conventional abdominal myomectomy, and to compare it with local instillation of vasopressin.Methods: 60 cases with symptomatic leiomyomata were recruited and planned for abdominal myomectomy, they were divided randomly into 3 groups, 20 cases in each. Group I, where local vasopressin was used, group II, where OA was used, and group III (the control group), where no specific medication was used and only free Saline was injected locally.Results: The overall results showed that OA group had significantly less operative time and less blood loss compared to control group. However, when compared to cases in group I, operative time and blood loss were significantly higher. Postoperative haemoglobin levels were significantly lower in group III compared to groups I (P = 0.039) and II (P = 0.044). Blood transfusion was indicated in 9 cases among group III, while only one case needed blood transfusion in group II, and no cases in group I.Conclusions: The use of local intra-myometrial OA is an option for reducing blood loss during myomectomy, but still efficacy is less than local vasopressin. This may be attributed to the low concentrations used, and to the less potency of OA as a vasoconstrictor agent.
