Pulmonary complications following urological, gastrointestinal and gynaecological abdominal Surgery––A post-hoc analysis of an observational study in 29 countries
Authors' conclusion
In this worldwide cohort of patients undergoing abdominal surgery, the incidence of PPCs varied across urological, gastrointestinal, and gynaecological surgery; the differences in incidence may be more strongly influenced by patient-related factors and anaesthesia duration than by the characteristics of the surgical specialty itself.

Primary result
As reported in the abstract
PPCs, unweighted
P < 0.001
Secondary outcomes
PPCs after propensity score weighting — Urological vs Gastrointestinal vs Gynaecological · across three groups · propensity score weighted cohort
P = 0.340
PPC risk scores
- Highest in urological, then gastrointestinal, then gynaecological
Individual PPCs
- Apart from unplanned supplementary oxygen, all PPCs most frequent after gastrointestinal and least after gynaecological surgery
