[Phantom rectum after Miles' operation].
The authors observed symptoms relating to the existence of a phantom rectum, a phenomenon about which little is still known, in 233 cases (32.1%) in a series of 724 patients undergoing amputation of the abdomino perineal rectum due to malignant neoplasm. The genesis of this phenomenon is attributed to an abnormal reactivity of the cortical and thalamic projection areas with greater response to stimuli from the stump or aspecific visceral stimuli, or even stimuli from the adjacent cortical regions. The psychodynamic aspects linked to the patient's need to develop a different body awareness should not be underestimated; this has to integrate a new anatomic reality, such as colostomy in the place of the anorectum, entailing the relinquishment of the previous body scheme. Prevention and treatment of phantom rectum, which is painful in 27% of cases, is essential for a correct operating technique, adequate psychotherapeutic support, the patient's active participation in a reeducation programme for colostomy management. It should not be forgotten that painful phantom rectum, especially with late onset, may be diagnostically significant as an indicator of the recurrence of neoplastic pathology, sometimes allowing diagnosis to be anticipated by several months. This underlines the importance of carrying out a careful postoperative clinical, biohumoral and radiological control in these patients, including pelvic CT. In the authors' experience of 233 patients suffering from phantom rectum, it was possible to document the presence of neoplastic recidivation in 30 cases (12.8%) using pelvic CT. In these cases, symptoms appeared after a disease-free interval of 26.3 months (range 3-75 months), whereas the presence of phantom rectum without recidivation is usually described in the first 2 months after surgery.
