Short‐term outcomes of intracorporeal anastomosis in laparoscopic colectomy for colon cancer: A nationwide, multi‐institutional cohort study in Japan (ICAN study)
Abstract
Several randomized controlled trials and meta‐analyses have demonstrated the potential advantages of intracorporeal over extracorporeal anastomosis. However, the heterogeneity and small samples of these studies complicate drawing clear conclusions regarding such advantages. In this nationwide, multicenter, retrospective cohort study, we aimed to clarify the benefits of intracorporeal over extracorporeal anastomosis in patients undergoing laparoscopic colectomy for colon cancer.
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design.
