ABOUT CLISTER

- Clinical Surgical Trials Epidemiological Research


Clister logotyp

Clister is a research group focusing on near patient surgical research. Our front line targets are advanced abdominal wall surgery and ostomy issues connected to malignant and benign disease. We study new screening methods, new surgical methods and new evaluation methods.


Within the field of proctology we handle the areas of abscesses, fistulas and incontinence. The methodologies we use are randomized studies, targeted clinical investigations, epidemiology, survey studies and collecting and analyzing biological material.


The research group leader, Ulf Gunnarsson, is a professor at the Department of Surgery at Umeå University, which is the starting point for a large amount of our research. Many of the studies within the group are national multicenter studies. We also have several Nordic cooperations.
