The midline of the dorsal column contains a pathway that may be more important for transmitting visceral nociceptive signals than the spinothalamic tract. Punctate midline myelotomy, a neuroablative operation with the intent of interrupting the midline of the dorsal column, has demonstrated efficacy in the treatment of otherwise intractable abdominal and pelvic cancer pain. The indications, technical procedure, outcomes, and complications of all published clinical studies of punctate midline myelotomy are reviewed. The lesion level of the spinal cord and the depth of the incision are discussed, with the focus on the feasibility of this technique.
