Clinical Trial Summary
Acute kidney injury (AKI) is a severe complication after liver resection and is associated
with morbidity and mortality. The incidence of postoperative AKI is significantly higher in
elderly patients, especially in those with comorbidities.
There is currently limited evidence on the incidence and associations of postoperative AKI in
elderly patients following liver resection.
This study will evaluate the incidence and associations of AKI in elderly patients after
liver resection and its impact on postoperative mortality.
Description:
The occurrence of postoperative AKI is independently associated with increased morbidity and
mortality. Advanced age reduces renal autoregulatory capacity due to physiological and
functional changes, thus render the elderly to suffer postoperative AKI and probably the
consequent chronic kidney disease.
Although elderly patients account for approximately 25% of surgical procedures, the incidence
and associations of AKI in this group of patients are rarely understood.
Thus, it is essential to identify those patients at high risk to develop postoperative AKI to
optimize perioperative prevention and protection strategies.
This study is a retrospective cohort study, aim to access risk factors of postoperative AKI
and its association with outcomes. The investigators will develop and validate a predictive
model for postoperative AKI.
The principal clinical outcome of the study is postoperative AKI, defined as an absolute
increase in serum creatinine of 0.3 mg/dL within 48 hours or a 1.5-fold increase from
preoperative baseline within seven days after surgery, according to the Kidney Disease:
Improving Global Outcomes (KDIGO) criterion.
