Prehabilitation and Its Role in Geriatric Surgery.

As the world's population ages rapidly, many elderly people are living to a much more advanced age than before. Consequently, medical conditions that require surgical interventions such as solid organ cancers are also getting more common. While young and fit patients may be able to withstand surgical stresses and recover rapidly after operation, older adults may find these challenging. Rehabilitation that is instituted in the postoperative period aims to help patients regain physical fitness and robustness to preoperative levels. However, recent studies have shown that prehabilitation may be more effective in bringing the fitness level of elderly patients to a higher level before they go for surgery. There are many controversies regarding the effectiveness of prehabilitation, the components of this intervention-be it mono- or multimodalities-and the duration of prehabilitation. This paper looks at the current evidence of this hot topic revolving geriatric surgery.
