Background
Encapsulating peritoneal sclerosis (EPS) is the most serious complication of peritoneal dialysis (PD) with a high mortality rate. The objective of the present study was to determine the clinical characteristics, the incidence rate, and the long-term outcome of EPS patients compared with control patients.
Methods
Two hundred and seventy patients with end-stage kidney disease were started on PD from 1987 to 2013 in the Juntendo University Hospital. EPS was diagnosed by clinical findings, radiological findings, and macroscopic inspection at the time of laparoscopy or surgical operation. Patient medical records were analyzed retrospectively, including clinical characteristics, laboratory findings, treatment modality, and outcomes. Using a Kaplan–Meier analysis, we compared the survival rate between EPS patients and control PD patients, matched for age, gender, diabetes, and duration of PD.
Results
Among 270 PD patients, 13 patients (4.8 %) developed EPS. The mean duration of PD was 120.5 ± 42.8 months. There were no significant difference in demographic findings between EPS and control PD patients. Among the EPS patients, seven patients died, of which four deaths were directly attributed to EPS. All four patients that had had surgical enterolysis were doing well and had no recurrences. No significant difference in the survival rate between EPS and control PD patients was observed in the Kaplan–Meier analysis.
Conclusions
There was no significant difference in the survival rate between EPS patients and control PD patients. It appears that an early diagnosis by laparoscopy and accurate treatment, including surgical enterolysis, might improve mortality.
