Encapsulating peritoneal sclerosis (EPS) is the most serious complication of long-term peritoneal dialysis (PD). EPS is diagnosed by clinical symptoms (abdominal pain, nausea, vomiting, diarrhea, and anorexia.) and image study (intestinal expansion, peritoneal thickening and calcification, and ascites.). Steroid therapy and surgery are recommended as the treatment of EPS. Here, we report a case of EPS with steroid-resistant massive ascites successfully treated with peritoneal lavage. A 59-year-old female with end-stage kidney disease secondary to hypertension was started on PD in 2003. Due to recurrent exit-site infection and two episodes of peritonitis, she was transferred to hemodialysis (HD), and her PD catheter was removed in 2011. In February 2012, six months after discontinuation of PD, she was found to have massive ascites on abdominal computerized tomography (CT). The patient was diagnosed to have EPS and was started on prednisolone. Despite eight months of prednisolone therapy, the ascites did not decrease. Therefore, the PD catheter was inserted again, and she was started on daily peritoneal lavage from September 2012. After four months of daily peritoneal lavage, her ascites disappeared in January 2013. The PD catheter was removed in July 2013. Steroid treatment was completed in May 2014, and there has been no recurrence of ascites since then. The evaluation of ascites by abdominal CT is important in a patient on long-term PD. Since EPS may appear any time after the discontinuation of PD, it is important to start screening abdominal CT shortly after the discontinuation of PD. Steroid-resistant massive ascites can be successfully treated with peritoneal lavage.
