Abstract:
Migration of the distal end of a ventriculoperitoneal shunt into the abdominal wall (epi-peritoneal layer) is a complication which is especially likely in obese patients with high intra-abdominal pressure and wide dead space around the catheter remaining after laparotomy. A preventive abdominal stitching method for this complication was developed consisting of sutures beside the catheter penetrating the peritoneum, posterior and anterior sheath of rectus abdominis muscle, and subcutaneous fat. This method was applied to more than 20 patients who underwent ventriculoperitoneal shunting. No patient experienced shunt migration. The technique is easy and safe to perform, avoids leaving a dead space around the peritoneal catheter, and prevents catheter migration.
