Collaboration in colorectal surgical research.

Surgical research has been under-powered, under-funded and under-delivered for decades. A solution may be to form large research collaborations and thereby enable implementation of successful interventional trials as well as robust international observational studies with thousands of patients. There are many such research collaborations in colorectal surgery, and in this paper we have highlighted the experiences from the West Midlands Research Collaborative (WMRC), the Scandinavian Surgical Outcomes Research Group (SSORG) and the European Society of Coloproctology. With active research networks, it is possible to deliver large, high-quality studies and provide high-level evidence for solving important clinical questions in an efficient and timely manner.
