[A Case of Encapsulated Peritoneal Sclerosis Associated with a Ventriculo-Peritoneal Shunt].

Abstract

We experienced a case of encapsulated peritoneal sclerosis(EPS)that developed as a result of peritoneal deterioration induced by ventriculo-peritoneal(VP)shunting. The patient was a 48-year-old man who underwent VP shunting five times since 1 month of age. Six months after the last operation, abdominal symptoms developed and the patient was hospitalized. A localized cyst was recognized in the left upper abdomen, and we diagnosed him with a cerebrospinal fluid pseudocyst. Soon, a shunt tube translocation was performed to another portion of the abdominal cavity, but a new short-term cyst appeared. During laparotomy, the inner surface of the abdominal cavity was very strong due to adhesions and the peritoneum was thickened. A large portion of the intestines and the mesentery was covered with a translucent film-like substance. Afterward, an ileus developed and he was diagnosed with EPS intraoperatively. We judged that an additional VP shunt was impossible, so a ventriculo-atrial shunt was placed. Afterward, his symptoms disappeared and the EPS improved. Although a few similar reports exist, this condition is thought to be extremely rare. Clinicians should recognize EPS as a complication of VP shunting.
