Charting connections: A systematic review of colorectal surgery research networks.

Research in surgery faces intrinsic difficulties such as the lack of reproducibility of surgical operations, self-referring surgeons, decentralized data. Establishing a community of qualified researchers across surgeons is crucial. Clinical networks have been proposed as solutions to many challenges in surgical research, yet their implementation remains uncommon, especially for surgical trialists. The extent of literature produced by networks remains unclear, but fostering such collaborations could enhance the overall quality of surgical research. We conducted review focusing on research networks in colorectal surgery to assess their workload and impact in the literature and identify factors contributing to their durability. Following PRISMA guidelines, we searched for articles published through research networks. Networks were categorized by subspecialty, and specific items were retrieved for further classification. A survey was administered to twenty experts in colorectal surgery or research networking. A total of 2490 manuscripts were screened, and 397 networks identified. Of these, 96 were colorectal networks contributing to 492 publications, with 28 networks having five or more publications. Seventeen networks were affiliated with International or National societies, and only 5 conducted both prospective trials and RCTs. Twenty networks reported national or population-based data, and 26 networks lasted for more than 5 years. Sixteen experts participated in the survey, with an 80 % compliance rate, and 12 of them have been involved in creating a surgical network. The large majority of experts advocate the establishment of guidelines for networks creation in the surgical community.
