▪ Content : Background and Objectives: Patients undergoing endoscopic gastrostomy (PEG) present with protein-energy
malnutrition (PEM) but little is known about zinc status. Our aim was to evaluate serum zinc, its relationship with
serum proteins and with the nature of the underlying disorder, during the first 3 months of PEG feeding. Methods and Study Design: Prospective observational study during a 3-month period after gastrostomy. Data was collected at initial PEG procedure (T0), after 4 (T1) and 12 weeks (T3). Initial evaluation included: age, gender, disorder causing dysphagia, Neurological Dysphagia (ND) or Head and Neck Cancer (HNC), NRS-2002, BMI, albumin, transferrin, zinc.
