title: Patient-controlled dietary schedule improves clinical outcome after gastrectomy for gastric cancer.
abstract: Although studies have shown that early oral feeding after abdominal surgery is feasible, the optimal dietary schedule has not been established. This study was conducted prospectively to compare the clinical outcome of patient-controlled dietary schedule with that of conventional dietary schedule after gastric resection for early cancer. Patients in the patient-controlled diet (PC) group (n = 53) received a solid diet on demand; patients in the conventional regimen (CR) group (n = 50) received a solid diet from postoperative day (POD) 10. All patients underwent distal gastrectomy for early gastric cancer. A liquid diet was tolerated by the PC group on POD 2, and a solid diet was taken on POD 6 after gastrectomy, earlier than in the CR group. The postoperative hospital stay was 18.5 +/- 5.9 days (10-40) in the PC group, versus 21.7 +/- 8.8 days (14-57) in the CR group (p = 0.02). Patients in the PC group had a higher daily oral intake of calories on POD 10 than those in the CR group (p = 0.02). Changes in body weight and serum albumin during the postoperative period and after discharge, and the incidence of complications and variances from clinical pathways did not show significant differences between the two groups. The PC schedule was feasible after distal gastrectomy for early gastric cancer. It improved the clinical outcome, with a shorter postoperative hospital stay and a higher oral energy intake on early phase, compared with the CR schedule. Moreover, the PC approach was useful for establishing the optimal dietary schedule and improving the clinical pathway.
