Abstract

PURPOSE
Colorectal resection for elderly patients is associated with significant morbidity and mortality. It is still unclear whether or not laparoscopic colorectal resection (Lap CR) is indicated in elderly patients. The aim of this study is to evaluate the outcome of colonic surgery in elderly patients and to assess the feasibility and safety of laparoscopic colorectal surgery in elderly patients.
METHODS
Patient characteristics and perioperative and pathologic data on 295 patients who underwent Lap CR for cancer from Jan. 2004 to Aug. 2011 were prospectively collected. Exclusion criteria were emergency and palliative by-pass surgery. Outcomes for elderly patients (> or =75 years) were compared with those of younger patients (<75 years).
RESULTS
In comparison of 257 younger patients (<75 years, median age 61 years), 38 elderly patients (> or =75 years, median age 79 years) showed a greater proportion off emale gender (52.6% vs. 37.0%, p=0.065) and American Society of Anesthesiologists score 2~3 (97.3% vs.42.0%, p<0.001). No differences in tumor location, median operative time, conversion rate, duration of hospital stay, and perioperative complications (23.7% vs. 30.0%, p=0.427) were observed between the two groups. Distributions of American Joint Committee on Cancer stages and number of harvested lymph nodes were comparable between groups.
CONCLUSION
Although elderly patients are more likely to be affected by co morbidities, postoperative outcome in this group after Lap CR is comparable with that of younger patients. Use of Lap CR in elderly patients is safe, and is associated with a low morbidity. It should be also regarded as the optimal approach for very elderly patients.
