Trial Evaluating the Tailored Versus the Systematic Use of Defunctioning Stoma After Total Mesorectal Excision for Rectal Cancer (GRECCAR17)

Summary

GRECCAR 17 will be the first prospective and randomized trial to assess a tailored policy in the use of defunctioning stoma after TME according to the personalized risk of anastomotic leakage. The tailored use of defunctioning stoma after TME for rectal cancer should improve both the quality of life of patients and the anorectal function, without any impact on anastomotic leakage. Moreover, for the healthcare system, this new approach could be a cost-effective strategy, leading to a decrease in healthcare expenses. The main objective is to compare the impact of tailored defunctioning stoma after TME for rectal cancer versus the systematic use of defunctioning stoma on the evolution of the specific Quality Of Life (QLQC30) during the 12 months after surgery.
