**12. Conclusion**

As surgeries with small incision are becoming mainstream, early discharge following the ERAS protocol is beneficial for the medical economics as well as for the patient's life. Methods of anesthesia that use anesthetics with minimal side effects and no postoperative residual effect, that provide sufficient postoperative analgesia, and that do not interfere with early mobilization are desirable. Elderly patients are also proactively undergoing surgery, and we hope that they get through the perioperative period smoothly and fully enjoy a 100-year-lifespan.
