Background: Gastrectomy often leads to malnutrition. Objective: The aim of this study was to analyze nutritional and digestive effects of gastrectomy for cancer. Patients and methods: Gastrectomized patients were studied by nutritional assessment including a weekly nutritional diary exploring digestive symptoms. Results: Thirty-two patients were analyzed after a mean follow-up of 41.8 months. The mean percentage of weight loss was 12.9% ± 13.5%. After total gastrectomy, mean weight loss was 22% ± 1.2%, against 7.4% ±11.9% for subtotal gastrectomy (p = 0.002). Moreover, advancing age was related to weight loss (p = 0.02), with a peak around 70 years. The most frequent postprandial symptoms were abdominal swelling (62%) and early satiety (59%). Finally, findings of the present study imply that overm a long follow-up, there are no specific intolerances related to gastrectomy. Conclusions: Patients who have undergone a total gastrectomy and elderly gastrectomized patients are at risk of malnutrition and need postoperative nutritional support.
