Backgrounds: Laparoscopic surgery has achieved good results in elderly patients with colorectal cancer (CRC). In this study, we compared the short-term and long-term outcomes of open surgery and laparoscopic surgery in CRC patients aged above 75 years at a single tertiary medical center.Methods: Between January 2009 and December 2015, we studied 967 patients who underwent curative resection for primary colorectal adenocarcinoma without distant metastasis in a single institution. Of the enrolled subjects, 305 underwent laparoscopic surgery, and 662 received open laparotomy surgery.Results: Compared to the patients who received open surgery, those received laparoscopic surgery had prominent shorter postoperative stay (10.3 vs. 13.5 days p < 0.001) and similar postoperative mortality (p = 0.082) and morbidity (p = 0.354). In the laparoscopy cohort, 6 of 305 patients were converted to open surgery and 1 died. The long-term overall survival, cancer-specific survival and recurrence rate were all similar between both cohorts in each stage.Conclusions: Laparoscopic surgery is suitable for elderly patients due to shorter postoperative stay, similar long-term outcomes with open surgery and acceptably low conversion rates. For long-term overall and oncological outcome, the results of laparoscopic surgery were similar to that of open surgery in each TNM stage.

Background: Laparoscopic surgery has achieved significant results in elderly patients with colorectal cancer (CRC). In this study, we compared the short-term and long-term outcomes of open surgery and laparoscopic surgery in patients with CRC aged above 75 years at a single tertiary medical center.Methods: We analyzed 967 patients who underwent curative resection for primary colorectal adenocarcinoma without distant metastasis between January 2009 and December 2015, in a single institution. Of the enrolled patients, 305 underwent laparoscopic surgery, and 662 received open laparotomy surgery.Results: Compared to the patients who underwent open surgery, those who received laparoscopic surgery had significantly shorter postoperative stay (10.3 vs. 13.5 days p < 0.001) and similar postoperative morbidity (p = 0.354) and mortality (p = 0.082). In the laparoscopy cohort, six of 305 patients were converted to open surgery and one died. The long-term overall survival, cancer-specific survival, and recurrence rate were similar between both cohorts in each stage.Conclusions: Laparoscopic surgery is suitable for elderly patients owing to shorter postoperative stay, similar long-term outcomes with open surgery, and acceptable low conversion rates.
