Comparison of staged repair versus single-stage complete repair for pulmonary atresia with ventricular septal defect: A systematic review and meta-analysis.

Aims: To evaluate comparative outcomes of the repair of pulmonary atresia with ventricular septal defect (PAVSD), done as staged repair (SR) or single-stage complete repair (CR).

Methods: A systematic online search was conducted using the following databases: PubMed, Scopus, Cochrane database, The Virtual Health Library, Clinical trials.gov, and ScienceDirect for studies comparing SR versus CR for treatment of PAVSD.

Do we need to routinely perform cavity shaving with breast-conserving surgery for breast cancer? A systematic review and meta-analysis.

Aims: To evaluate comparative outcomes of breast-conserving surgery (BCS) of breast cancer with and without cavity shaving.

Methods: A systematic search of multiple electronic data sources was conducted, and all randomised controlled trials (RCTs) comparing BCS with or without cavity shaving for breast cancer were included. Positive margin rate, second operation rate, operative time, post-operative haematoma, cosmetic appearance and budget cost were the evaluated outcome parameters for the meta-analysis.
