Proctectomy for rectal cancer in patients with prior spinal cord injury.
BACKGROUND
Limited published information is available concerning the clinical course of spinal cord injured (SCI) patients who later develop rectal cancer and undergo proctectomy. We hypothesized that such patients would have poorer outcomes than comparable neurally-intact patients.


METHODS
We conducted a retrospective study of all SCI veterans receiving care at all Department of Veterans Affairs (DVA) Medical Centers who subsequently underwent proctectomy for rectal cancer during fiscal years 1993-2002. Only patients with SCI due to trauma who met American Spinal Injury Association type A criteria (complete cord injury) were analyzed. The search strategy utilized DVA datasets plus data extracted from medical records.


RESULTS
There were 33,758 patients with ICD-9-CM diagnosis codes for SCI and 5246 patients with ICD-9-CM procedure codes for proctectomy due to rectal cancer; 72 patients were in both datasets. We received records for 72 patients and excluded 67 after chart review. Incorrect coding (44) and incomplete spinal cord lesions (9) were the most common exclusion criteria. Five patients were considered evaluable. The mean age at diagnosis was 65 (range 49-80). All five had symptomatic cancers and two (40%) had major comorbidities at admission. Postoperative complications occurred in four (80%). The winsorized mean length of stay was 28 days.


CONCLUSIONS
The complication rate and length of stay for SCI patients undergoing proctectomy for rectal cancer were higher than those reported for otherwise comparable neurally-intact patients. SCI should be considered a risk factor for adverse outcomes in operations for rectal cancer as in other major surgery.
