This systematic review and meta-analysis aims to investigate the effect of damage-control surgery on mortality in patients with non-traumatic abdominal emergencies. Literature search will be conducted using PubMed. Two meta-analyses will be performed comparing (1) mortality in patients with non-trauma damage control surgery vs. non-trauma conventional surgery and (2) the observed vs. expected mortality rate in patients undergoing non-trauma damage-control surgery.
After the successful implementation in trauma patients, damage control surgery (DCS) is being increasingly used in patients with non-traumatic abdominal emergencies, too. However, non-trauma DCS is an ongoing matter of debate as the open abdomen treatment typically performed in DCS is a non-anatomical situation and associated with potentially severe side effects. To date, DCS in patients with non-traumatic abdominal emergencies has not yet been comprehensively assessed in meta-analysis. A systematic literature search will be conducted using the National Library of Medicine's Medline database (PubMed). The search strategy will be based on the PICOS process. Original research articles in English language addressing (1) mortality in patients undergoing non-trauma DCS vs. non-trauma conventional surgery or (2) the observed vs. expected mortality in non-trauma DCS will be included. Two meta-analyses will be performed, comparing (1) mortality in patients undergoing non-trauma DCS vs. non-trauma conventional surgery and (2) the observed vs. expected mortality rate in patients undergoing non-trauma DCS based on outcome prediction scores. Meta-analysis will be performed using a random-effects model. The estimated effect size for mortality will be reported as risk difference with 95% confidence intervals. Sensitivity analysis will be performed by repeating the analysis in the subgroups of studies with the same study design and studies that applied the same outcome prediction score.
