ASSESSMENT OF SURGICAL RISK IN PATIENTS WITH CHRONIC LIVER DISEASE USING VOCAL PENN SCORE

For each patient and surgery,we will be collecting detailed pre-operative data regarding demographics (age, sex, body mass index, surgery category, comorbidities (diabetes mellitus, hypertension), and pertinent laboratory values (sodium, creatinine, total bilirubin, the international normalized ratio \[INR\], albumin, platelet count.) The etiology of liver disease will be classified. To ensure that laboratory data accurately reflected the pre-operative state, only those from within 30 days prior to surgery will be considered For each patient VOCAL PENN score, MELD score, and Mayo score will be calculated using an online calculator.
