Background Uterine fibroids are common, often symptomatic and a third of women need repeated time off work. Consequently 25% to 50% of women with fibroids receive surgical treatment, namely myomectomy or hysterectomy. Hysterectomy is the definitive treatment as fibroids are hormone dependent and frequently recurrent. Medical treatment aims to control symptoms in order to replace or delay surgery. This may improve the outcome of surgery and prevent recurrence. Purpose To determine whether any medical treatment can be recommended in the treatment of women with fibroids about to undergo surgery and in those for whom surgery is not planned based on currently available evidence. Study Selection Two authors independently identified randomised controlled trials (RCT) of all pharmacological treatments aimed at the treatment of fibroids from a list of references obtained by formal search of MEDLINE, EMBASE, Cochrane library, Science Citation Index, and ClinicalTrials.gov until December 2013. Data Extraction Two authors independently extracted data from identified studies. Data Synthesis A Bayesian network meta-analysis was performed following the National Institute for Health and Care Excellence—Decision Support Unit guidelines. Odds ratios, rate ratios, or mean differences with 95% credible intervals (CrI) were calculated. Results and Limitations A total of 75 RCT met the inclusion criteria, 47 of which were included in the network meta-analysis. The overall quality of evidence was very low. The network meta-analysis showed differing results for different outcomes. Conclusions There is currently insufficient evidence to recommend any medical treatment in the management of fibroids. Certain treatments have future promise however further, well designed RCTs are needed.

INTRODUCTION Intraoperative haemorrhage remains one of the major risks during liver resection, and perioperative blood loss and blood transfusion are important factors affecting perioperative morbidity and mortality. The aim of this study is to compare treatment strategies aiming to decrease blood loss during hepatectomy. METHODS A systematic review of the literature was performed to identify randomised controlled trials reporting on the method of vascular occlusion, parenchymal transection, and management of the cut surface during liver resection. A Bayesian network meta-analysis was performed using WinBUGS. RESULTS Seven trials reporting on 496 participants randomised to seven treatment strategies were analysed. Continuous vascular occlusion resulted in lower blood loss compared to no vascular occlusion when parenchymal transection was performed with clamp-crush and no fibrin sealant was used for the cut surface. People undergoing liver resection by continuous vascular occlusion had decreased amounts of blood transfused than people with intermittent vascular occlusion when parenchymal transection was performed with clamp-crush and no fibrin sealant. There was no significant difference in proportion of people transfused, mortality, or hospital stay between the different strategies. There were significantly more serious adverse events when surgery was performed using radiofrequency dissecting sealer compared with standard clamp-crush method in the absence of vascular occlusion and fibrin sealant. CONCLUSIONS Continuous vascular occlusion during hepatectomy results in decreased blood loss and decreased blood transfusion requirements. Further studies are needed to compare treatment strategies aiming to decrease blood loss, defined by their method of vascular occlusion, parenchymal transection, and management of the cut surface.
