Background: Since its first description in 1948, total pelvic exenteration has been a surgical option for the treatment of locally advanced rectal cancer in selected patients. During these 50 years, it has remained a formidable procedure with high mortality and substantial morbidity. This report describes the results of total pelvic exenteration for rectal cancer in terms of post-operative mortality, morbidity, and longterm survival in patients with locally advanced primary and recurrent rectal cancer.
Study design: A study of the patient records revealed that 24 patients underwent total pelvic exenteration as the treatment for locally advanced primary or recurrent cancer of the rectum from 1983 to 1998. The charts of the patients were reviewed, and morbidity and mortality were documented. The survival of the patients was also analyzed.
Results: Fifteen patients had primary tumor and 9 had locally recurrent cancer. The mean age was 62 years old. There were no postoperative deaths, and the complication rate was 54%. In the treatment of primary tumor, bowel continuity was possible in 60% of the patients. Previous radiation or operation for recurrent disease was not associated with increased morbidity. The overall 5-year survival was 44%. The 5-year survival of patients with primary cancer was 64% and was significantly better than the rate for those with recurrent disease. Only one patient with recurrent disease survived more than 24 months.
Conclusions: Total pelvic exenteration now can be performed with low mortality rates, but the morbidity remains high. In the treatment of primary rectal cancer, good survival (64%) can be achieved, but results are dismal for the treatment of recurrent disease. We suggest better selection of patients for this procedure, especially as a treatment for recurrent rectal cancer.
