RESUMO
Sclerosing encapsulating peritonitis(SEP) is now a well-recognised, but uncommon complication of chronic ambulatory peritoneal dialysis(CAPD). The etiology is unclear, but SEP is believed to be multifactorial. The most important factors seem to be the length of time on peritoneal dialysis and previous episodes of peritonitis. Anorexia, nausea, vomiting, weight loss, abdominal pain, and a reduction of the ability of the peritoneum to act as a dialyzing membrane are the usual presenting problems. We experienced one case of SEP presenting a huge pseudocyst in the patient of end stage renal failure on the maintenance hemodialysis for 5 years, even though he had a history of CAPD for 5 years. So we report this case with review of the literature.
