Multivisceral resection for advanced rectal cancer: outcomes and experience at a single institution

BackgroundMultivisceral resection is often required in the treatment of locally advanced rectal cancers. Such resections are relatively rare and oncologic outcomes, especially when sphincter preservation is performed, are not fully demonstrated.MethodsA retrospective review was conducted of patients who underwent multivisceral resection for locally advanced rectal cancer with and without sphincter preservation.ResultsSixty-one patients underwent multivisceral resection for rectal cancer from 2005 to 2013 with a median follow-up of 27.8 months. Five-year overall and disease-free survival were 49.2% and 45.3%, respectively. Thirty-four patients (55.7%) had sphincter-sparing operations with primary coloanal anastomosis and temporary stoma. There was no significant difference in overall or disease-free survival, or recurrence with sphincter preservation compared with those with permanent stoma.ConclusionsMultivisceral resection for locally advanced rectal cancer has acceptable oncologic and clinical outcomes. Sphincter preservation and subsequent reestablishment of gastrointestinal continuity does not impact oncologic outcomes and should be considered in many patients.
