Summary
Emergency colorectal resection in elderly patients carries high mortality. Over half of patients over 80 years old undergoing nonelective colorectal surgery died within one year, highlighting the need for improved survival strategies.
Area of Science:
- Geriatric Surgery
- Colorectal Surgery
- Public Health
Background:
- Colorectal resection in elderly patients is linked to substantial morbidity and mortality, particularly in emergency situations.
- Advanced age presents unique challenges in surgical outcomes.
Purpose of the Study:
- To quantify the risks associated with nonelective colorectal resection in elderly patients up to one year post-surgery.
- To analyze mortality and complication rates in different age groups of elderly patients undergoing emergency colorectal surgery.
Main Methods:
- Population-based observational study utilizing the Hospital Episode Statistics database.
- Inclusion of all patients aged 70 years and older undergoing nonelective colorectal resection in England (April 2001-March 2008).
- Primary outcomes included 30-day and 365-day mortality, 28-day readmission, and hospital stay duration.
Main Results:
- 36,767 nonelective colorectal resections were performed in patients aged ≥ 70 years.
- Thirty-day mortality rates increased with age: 17.0% (70-75), 23.3% (76-80), and 31.0% (>80).
- One-year mortality reached 51.2% for patients over 80; advanced age was an independent predictor of mortality.
Conclusions:
- Half of English patients over 80 undergoing nonelective colorectal resection died within one year.
- Significant cardiac and respiratory complications were noted in the oldest age group.
- Further research is needed to identify strategies to improve survival in this high-risk cohort.
