Scandinavian Surgical Outcomes Research Group (SSORG) started in 2008 as a network of colorectal surgeons with academic interest from six Swedish and four Danish hospitals (Read more in Läkartidningen).


The aim of the group is to scientifically evaluate surgical treatments and perform clinical research with an emphasis on large multicenter trials. We evaluate the safety and efficacy of treatments and with all the participating hospitals as a base for recruitment of patients we aim at a fast inclusion rate. Most of our trials include health related QoL as well as health economic end-points. 

Current projects

Diverticulitis – laparoscopic lavage vs resection (Hartman procedure) for acute diverticulitis with peritonitis (DILALA)

Robotic surgery for prostate cancer, laparoscopic prostatectomy robot or open (LAPPRO)
