Postoperative Functional Recovery After Gastrectomy in Patients Undergoing Enhanced Recovery After Surgery

Enhanced recovery after surgery (ERAS) is increasingly used in several abdominal surgeries to accelerate postoperative recovery and reduce the length of stay. The aim of this study was to investigate the pattern of functional recovery after gastrectomy in patients undergoing ERAS and to analyze factors that affect postoperative recovery.In all, 168 gastric cancer patients enrolled in a clinical trial evaluating ERAS compliance after gastrectomy were prospectively assessed with respect to postoperative functional recovery using discharge criteria, evaluating 4 major functional outcomes: adequate pain control, ability to mobilize and self-care, tolerance of oral intake, and no abnormal physical findings or laboratory test.The mean completion time of overall discharge criteria was 5.1  ±  3.2 days. The mean completion time for each dimension were 4.4  ±  0.9 days for adequate pain control, 4.1  ±  0.8 days for ability to mobilize and self-care, 4.3  ±  1.1 days for no abnormal physical signs or laboratory test, and 4.6  ±  1.2 days for tolerance of oral intake. The mean length of stay was 7.2  ±  3.2 days, and readmission rate was 2.4% (n = 4). There was 9.5% (n = 16) of morbidity and no hospital mortality. Female sex (P < 0.001) and age (≥ 65 years; P = 0.049) were significantly associated with a slower recovery in tolerance of oral intake, and total gastrectomy was significantly associated with delayed completion of adequate pain control (P = 0.003).Functional recovery after gastrectomy can be achieved after about 5 days in patients undergoing ERAS. Female sex, old age, and total gastrectomy are factors that delay normal functional recovery after gastrectomy.
