Abstract
PURPOSE
It has been proposed that laparoscopic colorectal surgery offers several benefits to patients. The aim of this study was to evaluate particularly whether older patients can benefit by laparoscopic colorectal procedures or if minimally invasive procedures are contraindicated.
METHODS
All patients who underwent elective surgery were divided into age-related groups: patients 50 years of age or younger, patients ranging from 51 to 70 years of age, and patients older than 70 years. The groups by age were compared with each other relative to their cardiopulmonary status, indication, procedure, conversion, morbidity, mortality, duration of surgery, perioperative blood transfusion, stay on the intensive care unit, and hospitalization. Statistical analysis included univariate analysis by chi-squared tests and Student's t-tests comparing patients older than 70 years with patients 50 years of age or younger and with patients ranging from 51 to 70 years of age (statistical significance was defined as P < 0.05).
RESULTS
Within five years 298 patients (male/female ratio, 0.38) underwent a laparoscopic or laparoscopic-assisted colorectal procedure. Of these, 95 (31.9 percent) patients were older than 70 years, 138 (46.3 percent) patients ranged from 51 to 70 years of age, and 65 (21.8 percent) patients were 50 years of age or younger. Pathologic findings in cardiopulmonary function increased with age. There were no statistically significant differences among the younger, middle-aged, and older patients relative to the incidence of conversion (3.1 vs. 9.4 vs. 7.4 percent, respectively), major complications (4.6 vs. 10.1 vs. 9.5 percent, respectively), minor complications (12.3 vs. 15.2 vs. 12.6 percent, respectively) or total laparotomy rate (7.7 vs. 12.3 vs. 12.6 percent, respectively). P > 0.05 for all comparisons. However, duration of surgery, stay on the intensive care unit, and postoperative hospitalization were significantly prolonged in patients older than 70 years (P < 0.05 for all comparisons) but were reduced during the five years of experience with these procedures.
CONCLUSIONS
If preoperative assessment of comorbid conditions and perioperative care was ensured, laparoscopic procedures were shown to be safe options in the elderly. The outcome of laparoscopic colorectal surgery in patients older than 70 years is similar to that noted in younger patients. Advanced age is no contraindication for laparoscopic colorectal surgery.
