This study aims to evaluate frailty using Short Physical Performance Battery (SPPB) before surgery and find out how frailty affects short-term postoperative recovery after surgery using Quality of Recovery-15 (QOR-15) questionnaire in patients undergoing minimally invasive distal gastrectomy for early gastric cancer.

As the elderly population increases, the evaluation and management of preoperative frailty is becoming important. In patients with frailty, exposure to external stress, such as surgery, can reduce physical function, increase postoperative complication, and raise the risk of death. This study aims to evaluate frailty using an automated device performing SPPB (Andantefit) and find out how frailty affects postoperative recovery.

Inclusion Criteria:

• Patients over 70 years of age, undergoing minimal invasive (laparoscopic, robot-assisted) distal gastrectomy for early gastric cancer, who can assess short-term postoperative recovery

Exclusion Criteria:

• Patients who have a difficulty in communication
• Patients who have a major medical or mental disease that can affect treatment outcome
• Patients unsuitable for this clinical trail on the opinion of researcher
