Nutritional management of patients undergoing surgery following diagnosis with encapsulating peritoneal sclerosis.

BACKGROUND: Encapsulating peritoneal sclerosis (EPS) is a rare but serious complication of peritoneal dialysis (PD). Gastrointestinal (GI) symptoms affect appetite and dietary intake. Adequate nutrition is especially important if surgical interventions are required. AIM: To investigate the nutritional management of 23 EPS patients that underwent surgical intervention between 1999 and 2005 at Manchester Royal Infirmary, United Kingdom.
METHODS: EPS was recognized by GI symptoms and diagnostically confirmed by laparotomy, computed tomographic scanning, or biopsy.
RESULTS: Mean time on PD was 74 months (interquartile range 42-89 months). During the 12 months pre-diagnosis, 65% of the group showed significant weight loss (p = 0.0001), with 8 patients losing >10% of body weight; 74% of patients experienced significant albumin decrease (p = 0.001); and 56% of patients experienced GI symptoms during the 6 months pre-diagnosis. Nasogastric (NG) feeding was recommended for 8 patients but continued in only 1. 15 patients (mean albumin 27 g/L) commenced parenteral nutrition (PN); 9 patients recovered, with albumin increasing over the 6-month follow-up. Mean hospital time was 62 days for the group receiving neither NG nor PN, compared with 124.3 for the PN/NG group (p = 0.04). In patients that died of EPS, albumin continued to fall at 3 months post-diagnosis.
CONCLUSION: There is currently little guidance for nutritional management of EPS. From this study we recommend (1) a high level of clinical suspicion for EPS, especially if PD patients have weight loss; (2) PN may be better than NG feeding but further studies into dual enteral nutrition and PN are needed; (3) aggressive nutritional supplementation pre- and postoperatively; and (4) dietitians need to recognize the high risk of refeeding syndrome.
