Gastrointestinal Surgery KI SÖS
The research at the colorectal department is focused on colorectal cancer, inflammatory bowel diseases and anal fistulas. Since 2005 we have a local register for colorectal cancer (KVALOG). The register also covers patients undergoing surgery for benign conditions (e.g. proctologic procedures, diverticular diseases and colorectal polyps) from 2011 . Since 2017, all patients undergoing rectal surgery are recorded according to a fast track program based on the same principals as ERAS (Enhanced recovery after surgery) called ERASS (ERAS Sös).

Upper Gastrointestinal Surgery group
The group runs studies aimed at improving diagnostics and treatment of diseases in the upper gastrointestinal canal. The projects are mainly focused on gallstone disease, acute pancreatitis, obesity, peptic ulcer disease and ultrasonographic diagnostics.
