Clinical Report: Impact of CHF and Comorbidities on Perioperative Outcomes in CRC Surgery

Overview

This study evaluated the influence of congestive heart failure (CHF) and other comorbid conditions on perioperative outcomes in colorectal cancer (CRC) patients undergoing surgery. Findings highlight that older age and multimorbidity, including CHF, significantly affect length of stay, readmission, reoperation rates, and overall survival.

Background

Colorectal cancer is a leading malignancy worldwide, with incidence increasing with age. Advances in surgical and anesthetic techniques have expanded surgery to older patients, who often present with multiple comorbidities. These comorbidities, including congestive heart failure, may impact perioperative outcomes and survival. Understanding these effects is crucial for optimizing preoperative assessment and tailoring multidisciplinary care for older CRC patients.

Data Highlights

The study included patients aged ≥40 years undergoing CRC surgery in Veneto, Italy, from 2013 to 2015. Outcomes measured were pre- and postoperative length of stay (LOS), 30-day readmission, 30-day reoperation, and 1-year overall survival (OS). Comorbidities were assessed using Charlson Index and Johns Hopkins ACG metrics. Age groups were stratified as 40–64, 65–74, 75–84, and ≥85 years. Surgical approach (open vs laparoscopic), Barthel Index, and surgical complexity were also analyzed.

Key Findings

• Older CRC patients with CHF and multiple comorbidities had longer pre- and postoperative hospital stays.
• Presence of CHF was associated with higher rates of 30-day readmission and reoperation following CRC surgery.
• Increasing age and multimorbidity correlated with decreased 1-year overall survival post-surgery.
• Laparoscopic surgical approach was more common in younger and less comorbid patients, potentially influencing outcomes.
• Functional dependency (lower Barthel Index) was linked to worse perioperative outcomes.

Clinical Implications

Comprehensive preoperative assessment including evaluation of CHF and other comorbidities is essential to stratify risk in CRC surgical patients. Tailored perioperative management and multidisciplinary care can potentially improve outcomes, especially in older and multimorbid patients. Consideration of surgical approach and functional status should guide individualized treatment planning.

Conclusion

Multimorbidity, particularly congestive heart failure, significantly impacts perioperative outcomes and survival in colorectal cancer surgery patients. Integrating comorbidity assessment into preoperative evaluation is critical to optimize care and improve surgical outcomes in this population.
