5-mFI is more accurate than ASA score in predicting postoperative mortality in rectal cancer: A case series of 109 patients.

Introduction: The aim of this study was to compare the accuracy of 5-mFI (modified frailty index) to ASA score (American Society of Anesthesiologists score) in predicting postoperative mortality in patients with rectal cancer.

Materials And Methods: The ability of each parameter to predict postoperative mortality was attested in 2 ways: Area under the curve (AUC) was determined using ROC curves analysis. A comparison of AUC was performed using Delong test and Henley-McNeil test.

Acute Gangrenous Cholecystitis: Proposal of a Score and Comparison with Previous Published Scores.

Background: Gangrenous cholecystitis (GC) is a particularly severe form of acute cholecystitis (AC) and is associated with an increased risk of postoperative morbidity and mortality. Recent reports show that surgeons are remarkably unsuccessful in diagnosing GC.

Methods: We conducted a retrospective study involving 587 patients with AC.
