Statistical analysis
Differences in demographic features, comorbidities and
surgical/pathological features between the two complication groups were
assessed using t-tests, chi squared test and Fisher’s exact tests as
appropriate. Statistically significant results were defined as those
with p value ≤ 0.05. Data was analysed with Stata v14 software
(StataCorp).
Ethics approval for this database was granted by the Prince Charles
