Efficiency Of Stair-Climbing Test For The Evaluation Of Cardiorespiratory Fitness In Aged Patients With Biliary Tract Disorder Undergoing Surgery

Objective: To investigate the efficiency of modified stair climbing test (SCT) for the evaluation of cardiorespiratory fitness in aged population of 80 yrs with biliary tract disorder. Methods: A total of 227 patients (male: 89, female: 138, averaged age: 83.3 yrs) aged more than 80 yrs with biliary tract disease were enrolled in this retrospective analysis. The patients were divided into surgery group (n=126, male: 54, female: 72) and non-surgery group (n=101, male: 41, female: 60) according to their willing. Ejection fraction (EF) was evaluated by qualified staff using the conventional methods. Modified SCT was used to determine the cardiorespiratory fitness. Results: Complete response was noticed in a large majority of 118 (93.65%) patients after surgery. In addition, a mortality rate of 6.35% was noticed. A total of 126 patients received SCT in the surgery group, and all the 101 patients received the questionnaire in the non-surgery group. A majority of patients showed climbing timing of less than 20 seconds, followed by timing of 20-30 seconds and more than 30 seconds. A smaller height in the SCT indicated less satisfactory cardiorespiratory fitness with a higher incidence of postoperative complication. Conclusions: The modified SCT could be considered as an effective predictor for mortality after surgery in aged patients aged of 80 yr or more with biliary tract disorder after surgery.
