Effective Remedy for Encapsulating Peritoneal Sclerosis with Ureteroileal Fistula

Abstract

Encapsulating peritoneal sclerosis (EPS), treated with surgical enterolysis as a final option, may become refractory to surgical intervention due to intraperitoneal complications. We report the case of a 59-year-old man presenting with EPS who underwent enterolysis at the age of 50, following 15 years of peritoneal dialysis (PD) and peritonitis. During the patient's first surgery, complete surgical enterolysis could not be performed due to severe intestinal adhesions with a deteriorated/calcified small bowel. Six months after the surgery, the obstructive bowel symptoms occurred several times a year. Nine years later, the patient suffered cystitis-like symptoms and fecal discharge from the urinary meatus. The patient was subsequently diagnosed with EPS recurrence with ureteroileal fistula between the right ureter and ileum. During the second surgical intervention, we conducted a divided jejunostomy, as surgical enterolysis and fistulectomy were unachievable due to severe ileal adhesion with calcified capsule and inflammation. Thereafter, symptoms reduced dramatically and oral intake became possible. Three years following surgery, the patient's condition is improved, with no evidence of EPS recurrence or cystitis-like symptoms. Although EPS with ureteroileal fistula is extremely rare, we propose that jejunostomy may be an effective treatment option for patients with EPS refractory to surgical enterolysis or intestinal bypass due to intraperitoneal complications.
