Transoral protrusion of a peritoneal catheter: a case report and literature review.

Transoral protrusion of a peritoneal catheter is rare. Only two cases have been reported in the English literature. We now report the case of a 5-year-old girl who presented with a catheter that had been inserted 4 years previously, protruding from her mouth. Signs of cerebrospinal fluid infection or peritonitis were absent. The peritoneal catheter was cut and externalized at the chest. The distal portion, which had perforated the stomach wall, was removed using endoscopic procedures. After 3 weeks of antibiotic treatment, a new shunt was inserted. Analysis of 50 cases of bowel perforation extracted from the English literature showed that among the suggested factors such as age, gender, nutritional state, history of abdominal surgery, and length and type of the catheter, age was the only predisposing factor. In the treatment of bowel perforation by a peritoneal catheter, suspected shunt infection should be managed properly and contamination be minimized during removal of the peritoneal catheter.
