Review Meta AnalysisT-tube drainage versus primary closure after open common bile duct exploration.
Between 5% and 11% of people undergoing cholecystectomy have common bile duct stones. Stones may be removed at the time of cholecystectomy by opening and clearing the common bile duct. The optimal technique is unclear. ⋯ T-tube drainage appeared to result in significantly longer operating time and hospital stay compared with primary closure without any apparent evidence of benefit on clinically important outcomes after open common bile duct exploration. Based on the currently available evidence, there is no justification for the routine use of T-tube drainage after open common bile duct exploration in patients with common bile duct stones. T-tube drainage should not be used outside well designed randomised clinical trials. More randomised trials comparing the effects of T-tube drainage versus primary closure after open common bile duct exploration may be needed. Such trials should be conducted with low risk of bias and assessing the long-term beneficial and harmful effects of T-tube drainage, including long-term complications such as bile stricture and recurrence of common bile duct stones.

Review Meta Analysis Comparative Study'Third wave' cognitive and behavioural therapies versus treatment as usual for depression.
So-called 'third wave' cognitive and behavioural therapies represent a new generation of psychological therapies that are increasingly being used in the treatment of psychological problems. However, the effectiveness and acceptability of third-wave cognitive and behavioural therapy (CBT) approaches as treatment for acute depression remain unclear. ⋯ Very low quality evidence suggests that third wave CBT approaches appear to be more effective than treatment as usual in the treatment of acute depression. The very small number of available studies and the diverse types of interventions and control comparators, together with methodological limitations, limit the ability to draw any conclusions on their effect in the short term or over a longer term. The increasing popularity of third wave CBT approaches in clinical practice underscores the importance of completing further studies of third wave CBT approaches in the treatment of acute depression, on a short- and long-term basis, to provide evidence of their effectiveness to policy-makers, clinicians and users of services.

Review Meta AnalysisExercise for improving outcomes after osteoporotic vertebral fracture.
Vertebral fractures are associated with increased morbidity (e.g., pain, reduced quality of life), and mortality. Therapeutic exercise is a non-pharmacologic conservative treatment that is often recommended for patients with vertebral fractures to reduce pain and restore functional movement. ⋯ No definitive conclusions can be made regarding the benefits of exercise for individuals with vertebral fracture. Although individual trials did report benefits for some pain, physical function and quality of life outcomes, the findings should be interpreted with caution given that findings were inconsistent and the quality of evidence was very low. The small number of trials and variability across trials limited our ability to pool outcomes or make conclusions. Evidence regarding the effects of exercise after vertebral fracture, particularly for men, is scarce. A high-quality randomized trial is needed to inform exercise prescription for individuals with vertebral fractures.

Review Meta Analysis Comparative StudyEndometrial resection and ablation versus hysterectomy for heavy menstrual bleeding.
Heavy menstrual bleeding (HMB), which includes both menorrhagia and metrorrhagia, is an important cause of ill health in women. Surgical treatment of HMB often follows failed or ineffective medical therapy. The definitive treatment is hysterectomy, but this is a major surgical procedure with significant physical and emotional complications, as well as social and economic costs. Several less invasive surgical techniques (e.g. transcervical resection of the endometrium (TCRE), laser approaches) and various methods of endometrial ablation have been developed with the purpose of improving menstrual symptoms by removing or ablating the entire thickness of the endometrium. ⋯ Endometrial resection and ablation offers an alternative to hysterectomy as a surgical treatment for heavy menstrual bleeding. Both procedures are effective, and satisfaction rates are high. Although hysterectomy is associated with longer operating time (particularly for the laparoscopic route), a longer recovery period and higher rates of postoperative complications, it offers permanent relief from heavy menstrual bleeding. The initial cost of endometrial destruction is significantly lower than that of hysterectomy, but, because retreatment is often necessary, the cost difference narrows over time.

Epilepsy is a common neurological condition which affects between 0.5% and 1% of the population. Approximately 30% of people with epilepsy do not respond to treatment with currently available drugs. The majority of these people have partial epilepsy. Vigabatrin is an antiepileptic drug licensed for use in the treatment of refractory epilepsy. No major side effects associated with the use of vigabatrin were detected by initial randomised controlled trials of the drug. However, longer-term observational studies have subsequently identified that its use is associated with asymptomatic visual field constriction. ⋯ This review of randomised controlled trials showed that vigabatrin can reduce seizure frequency in people with drug-resistant partial epilepsy. Short-term follow-up of patients showed that some side effects were associated with its use. Further analysis of longer-term observational studies is required to evaluate how likely patients are to develop visual field defects and whether such side effects are associated with dose and duration of drug use.
