Abstract
BACKGROUND: Pelvic exenteration is a procedure with high morbidity despite careful patient selection. This study investigates potential associations between perioperative markers and major postoperative complications including survival. METHODS: Retrospectively collected data for 195 consecutive patients who underwent total pelvic exenteration (January 2015-February 2020) at a single tertiary university hospital were analyzed. RESULTS: The 30-day mortality was 0.5%, and the rate of major postoperative complications (≥3 Clavien-Dindo) was 34.5%. Low albumin level (p = 0.02) and blood transfusion (p = 0.02) were significantly correlated with a major postoperative complication in univariate analyses. This had no impact on survival. Positive margins (p = 0.003), liver metastasis (p = 0.001) were related to poor survival in multivariate analyses for colorectal patients. A Charlson Comorbidity Index >6 (p < 0.05) was associated with poor survival in all patients. CONCLUSION: The occurrence of major postoperative complication does not negatively impact the overall survival. Pelvic exenteration is a potential life-prolonging operation when negative margins can be obtained, despite known risks for complications. Comorbidity is a predictor for inferior outcomes.
