A simplified technique for lengthening peritoneal catheters

Distal revision of ventriculoperitoneal shunts using a peel-away sheath

The authors describe a new technique for revision of an occluded distal ventriculoperitoneal shunt catheter that obviates the need for laparotomy or trocar insertion into the peritoneal cavity. The authors review their early experience with 34 patients suffering from a distal ventriculoperitoneal shunt failure and treated with this technique. There were no incidents of intraabdominal injury or wound complications. In 2 patients conversion to a minilaparotomy was required for safe placement of the shunt. Proper peritoneal placement was confirmed with abdominal radiographs in all cases. This technique has been safe and effective and may be considered an alternative to traditional laparotomy or laparoscopic methods.

Distal end revision of ventriculoperitoneal shunts sparing minilaparotomy. Technical note

Distal end malfunction of a ventriculoperitoneal shunt occurs secondary to outgrown, disconnected, fractured, or occluded peritoneal catheters. Replacement of such catheters normally requires a minilaparotomy. The authors describe a simple technique for peritoneal catheter replacement without minilaparotomy.
