For many decades adenomyosis has been a histological diagnosis in hysterectomy specimens. Traditionally, it has been considered a disease of late reproductive and premenopausal years causing uterine enlargement, dysmenorrhoea and menorrhagia. Recent advances in pelvic and uterine imaging techniques including transvaginal sonography and magnetic resonance imaging were responsible for a shift towards a non-invasive diagnosis and made a significant contribution to a better understanding of its pathogenesis, epidemiology, histological spectrum, and clinical s)mptomatology. With these non-invasive tools it has been shown that adenomyosis is probably a condition affecting much younger populations and is frequently asymptomatic at an early stage of its development. Regarding symptomatic disease, the distribution and extent of adenomyotic lesions do not correlate consistently with the various symptoms that are considered typical of adenomyosis. More importantly, accurate diagnosis of adenomyosis suffers from a lack of consensus among experts on imaging and even histological diagnostic criteria. Several pathogenetic theories have attempted to shed light on the establishment, evolution and distribution of adenomyotic lesions within the uterine wall, including the tissue injury and repair (TIAR) mechanism, metaplasia, and the more recent genetic-epigenetic theory. So far, none of these can adequately and independently explain the appearance of all types of adenomyosis. This review paper attempts a correlation between the proposed pathogenetic theories and the clinical and histological spectrum of adenomyosis, in an effort to give a plausible explanation of the evolution of this condition from an asymptomatic state to a disease, through synthesis of the existing data.

Myomectomy is the preferred surgical treatment for symptomatic women with uterine myomas who wish to preserve their fertility. The procedure may be associated with significant intraoperative blood loss, which predisposes to increased transfusion rates and morbidity. The objective of our systematic review and meta-analysis is to investigate whether intravenous (IV) use of tranexamic acid (TXA) may reduce blood loss during myomectomy. Three electronic databases were screened until June 2022. The eligible studies were assessed for risk of bias. Four randomized controlled trials that reported outcomes from a total of 310 women were finally included in the meta-analysis—155 patients received intravenous TXA while the remaining 155 received placebo injection with normal saline or water for injection. Total estimated blood loss was significantly lower in patients who received TXA before myomectomy compared to control (230 patients MD −227.09 mL 95% CI −426.26, −27.91, p = 0.03). This difference in favor of TXA group remained when intraoperative and postoperative blood loss was separately analyzed. Postoperative hematocrit values and hemoglobin levels did not differ among the two groups (180 patients MD 0.67% 95% CI −0.26, 1.59, p = 0.16 and 250 patients MD 0.17 mg/dL 95% CI 0.07, 0.41, p = 0.17, respectively). The number of patients that received blood transfusion was also not different (310 patients OR 0.46 95% CI −0.14, 1.49, p = 0.19). Total operative time was significantly prolonged in control group compared to TXA (310 patients MD −16.39 min 95% CI −31.44, −1.34 p = 0.03). Our data show that the IV use of TXA may significantly reduce intraoperative blood loss in patients undergoing myomectomy and contribute to reduced operative time.

Aim: Laparoscopic myomectomy may be associated with considerable blood loss, especially in patients in whom no specific hemostatic measures are used. We conducted this retrospective comparative study to investigate whether misoprosol is an effective and safe alternative to vasopressin when used as single hemostatic agent in laparoscopic myomectomy.Methods: Two hundred cases undergoing laparoscopic myomectomy (‐ies), were included. Of these, 50 pre‐treated with vaginal misoprostol 400mcg 1 h before surgery (group 1), were compared with two historic consecutive groups: 100 patients treated with intraoperative intra‐myometrial injection of dilute vasopressin (20 IU/100 mL normal saline) (group 2), and 50 treated without use of any hemostatic agent (group3).Results: Mean procedure length did not differ significantly between the three groups (127.9 vs 100.6 vs 130.8 min). Mean estimated blood loss (EBL) was 179.7 ± 200.0 mL in group 1, compared with 147.8 ± 171.8 mL in group 2 (P = 0.793) and 321.8 ± 246.0 mL in group 3, respectively (P < 0.001). EBL was lower in group 2 in most of the study's subgroups of patients stratified according to size and number of fibroids compared with group 1, with the exception of patients with ≥4 fibroids, and ≥7 cm in size. In these subgroups, misoprostol appeared more effective. Neither agent was associated with serious adverse events.Conclusion: Vaginal misoprostol can be effective in reducing blood loss during laparoscopic myomectomy. Although rates of EBL are, in general, higher compared with those obtained with vasopressin, they are significantly reduced compared with those observed when no hemostatic agent is used. In extended procedures, vaginal misoprostol, due to its prolonged uterotonic action, may be associated with reduced blood loss compared with vasopressin.
