Abstract

Abstract: Objective: Laparoscopy is a safe and effective treatment for colon cancer. However, its effects on short- and long-term health outcomes and medical utilization are not fully elucidated. This study aimed to compare short- and long-term utilization and health outcomes of colon cancer patients who underwent either laparoscopic or open surgery in a population-based cohort. Methods: This study was conducted by linking data from Taiwan Cancer Registry, National Health Insurance claims and Death Registry. Patients aged 18 and older with colon cancer between 2009 and 2012 were included in the study. Propensity score matching was used to minimize selection bias between laparoscopic and open surgery groups. Cox proportional hazard regression and generalized linear mixed logistic regression were used to test hypotheses. Results: Among the 11, 269 colon cancer patients who underwent colectomy, 3236 (28.72%) received laparoscopy and 8033 (71.28%) underwent open surgery. Patients who received laparoscopic surgery had better overall survival (HR = 0.82; 95% CI: 0.70–0.97). These patients also had lower 30 day mortality (0.44% vs. 0.91%), lower 1 year mortality (2.83% vs. 4.68%), lower overall occurrence of complications (6.16% vs. 8.77%), shorter mean length of stay (12.53 vs. 14.93 days) and lower cost for index hospitalization (US$4325.34 vs. US$4453.90). No significant differences were observed in medical utilization over a period of 365 days after the surgery. Conclusions: Our results demonstrate that, in both the short- and long-term post-operation periods, laparoscopic surgery reduced the likelihood of postoperative complications, 30 day, and 1 year mortality while being no more expensive than open surgery for colon cancer.
