Comparison of Short- and Long-term Outcomes of Laparoscopic and Open Right Hemicolectomy for Colon Cancer

Abstract

<br><b>Introduction:</b> Colorectal cancer is still among the most common malignancies in the world.</br> <br><b>Aim:</b> The aim of this study is to compare the outcomes of open and laparoscopic right hemicolectomy for colon cancer.</br> <br><b>Materials and methods:</b> This retrospective study included 87 patients who underwent laparoscopic and open right hemicolectomy for colon cancer between January 2014 and January 2020. Patients were categorized into two groups according to the surgical technique: laparoscopic (46 cases) and open (41 cases). Patient characteristics and clinicopathological findings, surgical findings, short- and long-term results were included in the evaluation parameters. Patients with pathological diagnosis other than adenocarcinoma, distant metastases, and incomplete file datas were excluded from the study.</br> <br><b>Results:</b> Forty-six (52.9%) patients underwent laparoscopic and 41 (47.1%) patients underwent open right hemicolectomy. The operation time of the laparoscopic group was found to be significantly higher (P<0.001). The amount of blood loss was significantly higher in the open group (P < 0.001). The incidence of post-operative complications in the open group (26.8%) was higher than in the laparoscopic group (6.5%) (P = 0.010). The rate of anastomotic leakage (9.8%) was higher in patients who underwent open surgery compared to laparoscopic group (0%) (P = 0.045). It was found that the laparoscopic group had a shorter hospital stay (P = 0.009). No statistically significant differences were found between the groups in terms of overall overall survival (OS) rate (P = 0.400) and disease-free survival (DFS) rate (P = 0.781).</br> <br><b>Conclusion:</b> Laparoscopic right hemicolectomy for colon cancer is a feasible and reliable method with lower postoperative morbidity and similar long-term results to the open method.</br>
