Aims: The aim of this study was to examine the perioperative nutritional status, body mass indices (BMI) and nutritional intakes of patients undergoing a modified D2 gastrectomy (preserving pancreas and spleen) for carcinoma to determine whether a relationship exists between the above and outcomes. Methods: Fifty consecutive patients [median age 71 years, 38 male] with gastric adenocarcinoma were studied prospectively. Results: Seven patients (14%) were obese (BMI > 30 kg/m(2)), 16 patients (32%) were overweight (BMI > 25 kg/m2), 21 patients (42%) were of normal weight (BMI 20-25 kg/m2), and six patients (12%) were underweight (BMI<20kg/m(2)). Operative morbidity was commoner in underweight patients (33%) when compared with overweight patients (17%, P = 0.391) and patients of normal weight (14%, P = 0.289). Fatal complications, however (two patients, 4%) were confined to overweight patients (P = 0.118). Preoperative serum albumin levels were significantly higher in overweight patients (43 g/dl) compared to underweight patients (34.5 g/dl; P = 0.003), though no correlation was found between patients' serum albumin levels and postoperative morbidity (r = -0.023, P = 0.877). Overweight patients were significantly less likely to achieve their protein requirements postoperatively than underweight patients (P = 0.037). Early enteral feeding contributed to 56% of the median energy requirements and 45% of the median protein requirements on the seventh postoperative day. Conclusion: BMI alone is a poor indicator of outcomes after modified D2 gastrectomy for carcinoma. The role of early enteral nutrition in patients undergoing gastrectomy for cancer deserves further evaluation. (C) 2003 Elsevier Ltd. All rights reserved.
