Redundant publication of systematic reviews and meta-analyses (SRs/MAs) on the same topic presents an increasing burden for clinicians. The aim of this study was to describe variabilities in effect size and methodological quality of overlapping surgery-related SRs/MAs and to investigate factors associated with their postpublication citations. ⋯ Overlapping SRs/MAs with high variability in results and methodological quality were common in surgery. A high-quality SR/MA score was an independent predictor of more frequent citations. Researchers and journal editors should concentrate their efforts on limiting publications to higher-quality reviews.

Colorectal cancer (CRC) is the second most common solid organ cancer. Traditional treatment is with surgery and chemotherapy. Immunotherapy has recently emerged as a neoadjuvant therapy that could change treatment strategy in both primary resectable and metastatic CRC. ⋯ Early data on the effect of immunotherapy in CRC provide new strategic thinking of treatment options in CRC for both early-stage and advanced disease, with prospects for new trials.

The pressure on liver-transplant programmes has expanded the usage of extended-criteria allografts. Machine perfusion may be better than conventional static cold storage (SCS) in alleviating ischaemia-reperfusion injury in this setting. Recipient outcomes with hypothermic or normothermic machine perfusion were assessed against SCS here. ⋯ Machine perfusion assists some outcomes with potential cost savings.
