RÉSUMÉ
Objective To analyze the safety and efficacy of laparoscopic radical resection of colorectal cancer for elderly patients over 70 years old. Methods From January 2014 to January 2017,a retrospective analysis of the patients with radical surgery for colorectal cancer in Department of General Surgery,Beijing Anzhen Hospital,Capital Medical University was performed. According to the patient′s age, the patients were divided into ≥70 years old group (68 cases) and＜70 years old group (84 cases). The preoperative clinical data of the two groups were analyzed. The surgeons strictly followed the standard lymph node cleaning and the principle of no tumor for colorectal cancer radical operation. The surgical conditions, pathology,short-term efficacy and the follow-up conditions of the two groups were compared. Statistical analysis was performed using SPSS 20. 0. The normal distribution of the data was expressed as Mean±SD,and the t-test was used for comparison between the group. The count data was compared using the χ2 test or the Fisher exact probability method. Results The operation was successfully completed in both groups. In the group of≥70 years old,2 cases were converted to open due to extensive adhesion of the abdominal cavity,no perioperative death. Compared with the＜70 years old group,≥70 years old group had more hypertension and coronary heart disease, respectively ( 38. 2%( 26/68 ) vs. 14. 3%( 12/84 )), and the difference was statistically significant ( P＜0. 05 ) . There was no significant difference in intraoperative blood loss and operation time between the two groups (P＞0. 05) . There was statistically significant difference in incidence of postoperative cardiovascular events between the groups (26. 4%(18/68) vs. 7. 14%(6/84)χ2＝ 6. 428, P＝0. 010) . However,there were no significant differences between the two groups in implications,rate of death and the time stayed in hospital. (P＞0. 05). Conclusion Laparoscopic radical resection for colorectal cancer patients over 70 years old is safe and feasible with strict indications and attention to perioperative management.
