Összefoglaló szövege

Prehabilitation is a preoperative program aiming to improve patients’ physical condition through exercise, nutrition and psychological support to overcome subsequent surgical stress. Prehabilitation is widely investigated in colorectal surgery, where the most feared complication is anastomotic leak, which has several modifiable preoperative risk factors potentially affected by exercise as the main element of prehabilitation. However, its effectiveness is controversial as the large heterogeneity of exercise protocols hampers comparative research. Distinct forms of exercise, like endurance or resistance training, induce different physiological responses, which may affect postoperative outcomes differently, thus, consensus is needed on the applied protocol.
We aimed to compare the effect of resistance and endurance training on anastomotic healing in a high-risk colon anastomosis model.
After 4 weeks of sedentary (S), endurance (E) and resistance (R) exercise based prehabilitation protocols male Wistar rats were divided into low (S, E, R) and high surgical risk (SC, EC, RC) groups depending on wether colitis (C) was induced or not prior to colon resection. Changes in exercise performance and body composition by magnetic resonance imaging were analyzed before surgery. Colitis activity was estimated by the Disease Activity Index (DAI) score. Postoperative vulnerability was measured by determining survival, weight loss and Rat Grimace Scale (RGS). Anastomotic leak and healing were assessed by adhesion score and anastomotic bursting pressure measurement.
Increased resistance exercise performance indicated improved muscle strength in the R and RC groups, enhanced aerobic training capacity suggested higher endurance in the E and EC groups compared to the other groups. The colitis activity was reduced in both the RC and EC groups, as shown by lower DAI than the SC group. Postoperative outcome improved in the RC but not in the EC group, indicated by increased survival, reduced body weight loss and lower RGS compared to the SC group. While anastomotic healing also ameliorated in the RC but not in the EC group showed by less adhesion and elevated bursting pressure compared to the SC group.
Resistance but not endurance training-based prehabilitation protocols improve anastomotic healing and promote postoperative recovery.
