Innovation and Tribulation in the History of Randomized Controlled Trials in Surgery.
Despite persistent critiques of the rigor of surgical research, surgeons have actually pursued careful empirical studies for centuries. Their work has enriched not only surgical science but also the development of evidencebased medicine. From conducting landmark controlled trials, to using statistics, alternate patient allocation, randomization, and sham controls, surgeons have long embraced innovative trial approaches and played important roles in the development of key methods of RCTs. ⋯ Surgical trialists also have encountered specific, recurring challenges, especially with the methodological and ethical complexity of blinded and sham-controlled trials. The history of surgical trials thus reveals major contributions from surgeons to the advancement of evidence-based medicine, as well as ongoing challenges. Strengthened and systematic trial support could advance the future of surgical RCTs.

Time to surgery (TTS) is of concern to patients diagnosed with cancer and their physicians. Controversy surrounds the impact of TTS on colon cancer survival. There are limited national data evaluating the association; thus, our aim was to estimate the overall survival (OS) impact from increasing TTS for patients with colon cancer. ⋯ TTS is independently associated with OS and this represents a public health issue that should be addressed at a national level. Although time is required for evaluation before surgery, efforts to reduce TTS should be pursued.

To develop a nomogram to estimate the risk of SPLD (International Study Group of Liver Surgery definition grade B or C) and long-term survival in patients with HCC before hepatectomy. ⋯ The nomogram showed good performance in predicting both SPLD and OS. It could help surgeons select suitable HCC patients for hepatectomy.

To investigate the role of bacterial- mediated plasminogen (PLG) activation in the pathogenesis of anastomotic leak (AL) and its mitigation by tranexamic acid (TXA). ⋯ Bacterial activation of host PLG is central to collagenolysis and pathogen-mediated AL. TXA inhibits this process both in vitro and in vivo. TXA enema represents a promising method to prevent AL in high-risk sites such as the colorectal anastomoses.
