POSSUM scores may overestimate risk after laparoscopic colectomy; challenges their accuracy and leaves open need for recalibrated models.
Do POSSUM and P-POSSUM scoring systems accurately predict morbidity and mortality after laparoscopic colectomy?
Standard POSSUM and P-POSSUM scoring systems overpredict morbidity and mortality in laparoscopic colectomy unless the operative severity score is adjusted.
