POSSUM models may overestimate risk after laparoscopic colorectal resection; challenges their validity and leaves open recalibration for minimally invasive cohorts.
Do POSSUM, P-POSSUM, and CR-POSSUM accurately predict mortality and morbidity in patients undergoing laparoscopic colorectal resection?
POSSUM, P-POSSUM, and CR-POSSUM scoring systems overestimate mortality and morbidity in patients undergoing laparoscopic colorectal resection, though they may be accurate for patients requiring conversion to open surgery.
