Abstract: Post-gastrectomy syndromes evoked by the loss of several gastric functions after total or subtotal gastrectomy are very common. Different kinds of reconstruction have been developed to overcome this problem. Patients with preservation of the duodenal passage in jejunal interposition with or without a pouch show a better quality of life and minimal postoperative symptoms. A jejunal interposition with or without a pouch after proximal or distal subtotal gastrectomy seems to improve the nutritional state and quality of life. The prognostic nutritional index (PNI), Visik Score, Spitzer Index and The European Organization for Research and Treatment of Cancer (EORTC) questionnaire (QLQ-C30) are available to evaluate the quality of life and nutritional status after gastrectomy.
