Background: To evaluate morbidity, mortality, and long-term survival in patients undergoing partial or total cystectomy during en bloc resection for locally advanced colorectal cancer.
Methods: This study retrospectively evaluated the outcome of combined bladder resection for colorectal cancer in our department.
Results: Patients (n=33) with colorectal tumors adherent to the bladder were followed. Overall morbidity was 11/33 (33.3%). Histological staging demonstrated inflammatory adhesion in 54.5% (18/33) and invasion in 45.6% (15/33). Morbidity was significantly higher in those that had undergone total cystectomy than in those that had undergone partial cystectomy (4/5 vs 7/28, P=0.033). The local recurrence has no difference the between total cystectomy group and the partial cystectomy group (1/5 vs 8/28, P=1.000). Overall 5-year survival rate was 39.4% (13/33). Mean survival time was 46.6875 month. There was no difference in 5-year survival between patients with inflammatory adhesion vs those with tumorous infiltration between colorectal tumor and bladder (P=0.7389).
Conclusion: Survival after surgery for colorectal cancer is not influenced by the need to excise part or all of the urinary bladder in case it is contiguous to a colorectal tumor. Experienced surgeons in urology and colon and rectal surgery should be left to decide on the surgical options to be employed.
