We report on a patient with residual complaints after an operation for lumber canal stenosis, successfully treated with the Kampo medicine, kigikenchutokauzu. The patient was 69 year-old woman complaining of severe coldness, numbness, and bilateral leg pain. She was diagnosed as having spinal canal stenosis when she was 67 years of age. Posterolateral fusion with laminectomy was performed at the age of 69, although severe coldness, numbness, and pain persisted even after her surgery. Also, her sutures had not healed. She was referred to our department 26 days after her surgery in order to receive Kampo therapy. Kigikenchutokauzu was prescribed, and her condition markedly improved. Her sutures healed completely 7 days after start of administration. This suggests that kigikenchutokauzu may be effective not only for the residual spinal canal stenosis symptoms, but also for the postoperative healing of sutures.lumber spinal canal stenosis, kigikenchuto, cold sensation of lower extremity, postoperative wound healing
