Acute Kidney Injury in Major Abdominal Surgery: Retrospective Study of 501 Patients

Acute Kidney Injury in Major Abdominal Surgery: Retrospective Study of 501 Patients


Lead Sponsor: Uppsala University

Brief Summary

Retrospective study that aims to examine the presence of acute kidney injury (AKI) during major abdominal surgery, non- cardiac surgery. Using clinical and biochemical data in order to establish AKI frequency and risk factors.

Detailed Description

Ethical approval was submitted and approved by the regional ethical committee, Etisk prövningsnämnd Uppsala, # 2017/418.

Patients were selected from the time span of april 2016 to september 2017. The investigators identified 499 patients that had undergone any of the selected procedures. The procedures were, pancreatic resection, HIPEC surgery in colorectal setting, gynecological debulking in metastasized ovarian cancer, and liver resection.

The risk of acute kidney injury (AKI) by the KDIGO definition during the postoperative period will be estimated in the group as a whole, and for each type of surgery separately. In addition the data will be stratified by sex to investigate systematic gender disparities or physiological differences. Length of stay, thirty day and sixty day mortality will secondary endpoints.
