Review Meta Analysis Comparative Study
Endoscopic versus microscopic transsphenoidal surgery in the treatment of pituitary adenoma: a systematic review and meta-analysis.
Inconsistent findings have been reported regarding the efficacy and safety of endoscopic and microscopic transsphenoidal surgery for pituitary adenoma. This study aimed to assess the benefits and shortcomings of these surgical methods in patients with pituitary adenoma. ⋯ Endoscopic transsphenoidal surgery is associated with higher gross tumor removal and lower incidence of septal perforation in patients with pituitary adenoma. Future large-scale prospective randomized controlled trials are needed to verify these findings.

Review Meta Analysis
Risk factors for cement leakage after vertebroplasty or kyphoplasty: a meta-analysis of published evidence.
Cement leakage is the most common complication of vertebroplasty and kyphoplasty. So far, the reported risk factors remain conflicting because of limited data and lack of uniform measurement and evaluation. Here, we performed a systematic review and meta-analysis of potential risk factors for cement leakage after vertebroplasty or kyphoplasty. ⋯ The results of this meta-analysis suggest that patients with intravertebral cleft, cortical disruption, low cement viscosity, and high volume of injected cement may be at high risk for cement leakage after vertebroplasty or kyphoplasty. Rigorous patient selection and individual therapeutic strategy irrespective of age, sex and fracture type, operation level, and surgical approach may reduce the occurrence of cement leakage. Given the inherent limitation of the meta-analysis, more large sample-sized randomized controlled trials are needed to further validate the present findings.
