The aging population is rapidly increasing the volume and complexity of geriatric surgery, with a growing number of elective and emergency procedures. Older adults may gain substantial benefits from surgery, yet they face higher vulnerability to complications and slower recovery due to reduced physiological reserve and frailty, which is distinct from multimorbidity. Decision-making must therefore be individualized, integrating patient preferences, functional status, and long-term goals. Risk stratification requires multidimensional approaches combining American Society of Anesthesiologists (ASA) status, Charlson Comorbidity Index and frailty indices. Preoperative optimization including comorbidity management, nutritional support and prehabilitation, polypharmacy review, and cognitive/functional screening—reduces complications and healthcare costs. Intraoperatively, careful anesthetic dosing, goal-directed fluid therapy, temperature control, and continuous monitoring are essential; delirium prevention relies on minimizing deliriogenic drugs, ensuring orientation, promoting mobilization, and maintaining hydration. Specialty-specific considerations must be taken into account. Preoperative multidisciplinary team discussions enhance decision-making and outcomes. Postoperative Enhanced Recovery After Surgery (ERAS®) strategies emphasize early feeding, multimodal analgesia, mobilization, and prevention of delirium, infection, venous thromboembolism, and pressure ulcers. Future perspectives involve precision medicine, artificial intelligence, telemedicine, and dedicated geriatric surgical pathways.
