Abstract

PURPOSE: The purpose of this study is to assess the periopertive morbidity and mortality rates in relation to the principal variables in aged patients who undergo laparoscopic colorectal resection.
METHODS
From March 2001 to March 2006, the prospective laparoscopic colorectal resection database was used to identify 233 patients. Among them, 132 were 70 years of age or older and they were classified as the aged group. 101 were younger than 70 years of age and they were classified as the younger group.
RESULTS
Comorbidity was more common in the aged group than in the younger group (67.4% and 53.5%, respectively) (P=0.030). There were higher ASA scores in the aged group (I: 2.3% II: 68.2% III: 29.5%) than in the younger group (I: 27.7% II: 56.4% III: 15.8%) (P<0.0001). There was a higher postoperative complication rate for the aged group than for the younger group (25.0% and 8.9%, respectively) (P=0.002). Only one case of mortality (0.8%) was found in the aged group. The period of the postoperative hospital stay was longer for the aged group than that for the younger group (21.9+/-3/416.3 days and 16.3+/-3/48.1days, respectively) (P= 0.002). For the aged group, univariate analysis revealed that the operative procedure, disease, the T stage and the operation time were significant variables for the postoperative complications, and multivariate analysis identified the operation time as an independent variable faor the postoperative complications.
CONCLUSION
More prudent care is needed to prevent postoperative complications for the aged patients who undergo laparoscopic colorectal resection, and particularly for those who can be expected to have a longer operation time.
