Encapsulating peritoneal sclerosis (EPS) is a complication of peritoneal dialysis. Although incidence is low, for patients who do develop the condition it can be debilitating and life-threatening. It has therefore received great interest and awareness from the renal community in the last 10 years. EPS is usually a progressive condition, with early clinical signs ranging from mild gastrointestinal (GI) symptoms and weight loss, to inflammation, severe GI symptoms and, eventually, encapsulation. Over time, the clinical picture deteriorates, affecting biochemistry, nutritional status, overall health and quality of life, which can eventually be fatal. A multidisciplinary approach and high index of suspicion are needed to identify patients at risk of developing EPS, so early diagnosis can be made and timely treatment initiated. Thorough nutritional assessment, monitoring and support are essential. This article raises awareness of EPS, describes how to optimise nutritional care, and hopes to improve patient outcomes through earlier identification and intervention of this potentially devastating disease.
