Gastrointestinal Surgery KI SÖS – Gabriel Sandblom's research group

Colorectal surgery

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).

Projects

STAR-TREC: Can we Save the rectum by Watchful waiting or TransAnal microsurgery following (chemo) Radiotherapy versus Total mesorectal excision for early Rectal Cancer?
Randomized international multicenter study. Includes patients with rectal cancer cT1-T3bN0M0. Patients are randomized to TME surgery or organ-sparing surgery with chemoradiotherapy or radiotherapy alone. 

EROS: Early intervention and recovery of sexual function in men and women after treatment of rectal cancer– a randomized controlled study with tadalafil compared to standard care. 
Includes patients with rectal cancer stages I-III. Measures change in sexual function from start of treatment to24 months postoperatively with/without Tadalafil.

Upper Gastrointestinal Surgery group / Abdominal wall surgery

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.

Acute surgery

At the department of acute surgery and abdominal wall surgery acute abdominal conditions are managed, e.g. appendicitis, acute pancreatitis and cholecystitis. Planned hernia surgery is also performed at the department. A number of studies focused on acute gastrointestinal conditions and abdominal wall surgery are conducted at the section.
