title: Impact of preoperative regular physical activity on postoperative course after open abdominal aortic aneurysm surgery.
abstract: Early ambulation after open abdominal aortic aneurysm (AAA) surgery is assumed to play a key role in preventing postoperative complications and reducing hospital length of stay. However, the factors predicting early ambulation after open AAA surgery have not yet been sufficiently investigated. Here, we investigated which preoperative and intraoperative variables are associated with start time for ambulation in patients after open AAA surgery. A total of 67 consecutive patients undergoing open AAA surgery were included in the study [male, 62 (92 %); mean age, 68 years (range, 47-82 years), mean AAA diameter, 53 mm (range, 28-80 mm)]. Preoperative physical activity was examined by means of 6-min walk distance (6MWD) and a medical interview. Patients were divided into two groups, according to when independence in walking was attained: early group <3 days (n = 36) and late group ≥3 days (n = 31), and the pre-, intra-, and postoperative recovery data were compared. There were no significant differences in patient baseline characteristics or intraoperative data between the two groups. The number of patients engaging in preoperative regular physical activity and 6MWD were significantly greater (p = 0.042 and p = 0.034, respectively) in the early group than in the late group. In addition, time to hospital discharge was significantly shorter in the early group than in the late group (p = 0.031). Binary logistic regression analysis showed that preoperative regular physical activity was the only independent factor for identifying patients in the early group (odds ratio 2.769, 95 % confidence interval 1.024-7.487, p = 0.045). These results suggest that engaging in regular physical activity is an effective predictor of early ambulation after open AAA surgery.
