Review Meta Analysis
The impact of intraoperative vascular occlusion during liver surgery on postoperative peak ALT levels: A systematic review and meta-analysis.
Intraoperative vascular occlusion techniques during liver surgeries have been performed and refined for decades. However, the impact of these techniques on postoperative peak ALT levels remains uncertain. Thus, we performed a literature review and meta-analysis to determine the impact of intraoperative vascular occlusion during liver surgery on postoperative peak ALT levels. ⋯ Intraoperative vascular occlusion, especially intermittent inflow occlusion and Pringle's maneuver vascular occlusions, may be a potential risk factor that could lead higher postoperative peak ALT values than non-occlusion procedures for liver surgeries.

The objective of this systematic review was to identify the effectiveness of percutaneous endoscopic lumbar discectomy (PELD) in the treatment of recurrent lumbar disc herniation (rLDH) and to present its indications and techniques. We conducted a comprehensive search in MEDLINE, EMBASE, PubMed, Web of Science and Cochrane databases, searching for relevant studies of managing rLDH with PELD up to July 2015. Only papers published in English were included. ⋯ In conclusion, according to the current evidence, PELD is an effective procedure for the treatment of rLDH in terms of reducing complication and shorting hospital course, comparing with OD. Therefore, we suggested that PELD was a feasible alternative to OD in the treatment of the rLDH in the condition of proper indication. High-quality RCTs with large sample sizes are needed to further confirm these results.
