Kestle, John R. W. | Assessing the validity of the endoscopic shunt insertion trial: did surgical experience affect the results? | Object. Most surgical procedures are associated with a learning curve in which the success rate is lower early in the experience before mistakes have been identified and modifications made to the procedure. Negative results obtained early in a trial's learning curve may be a matter of timing rather ... | Endoscopic shunt insertion; Ventriculoperitoneal shunt; Pediatric neurosurgery; Surgical experience | 2004-01-01 |
