title: Revision of ventriculo-peritoneal shunt under laparoscopic guidance in patients with hydrocephalus.
abstract: Ventriculo-peritoneal (V-P) shunt is a common treatment for hydrocephalus. However, shunt insufficiency due to obstruction, dislocation, and detachment of the peritoneal tube is frequently encountered. We designed a new technique in which the peritoneal tube is inserted into a target site of the abdominal cavity under laparoscopic guidance. We operated on 9 patients with hydrocephalus using this technique. Shunt insufficiency of the peritoneal tube had been observed in all patients, and 7 patients had undergone repeated revision of the peritoneal tube before this procedure. Our laparoscopic-assisted method ensured tube insertion into the appropriate site, and minimized the abdominal wound and postoperative adhesions. This method also made it possible to differentiate abdominal pain induced by shunt failure from pain caused by other diseases, including appendicitis. In conclusion, we consider this new technique for V-P shunt performed under laparoscopic guidance to be very useful.
