Comparison of Histopathological and Oncological Results of Patients Who Underwent Laparoscopic or Open Resection for Sigmoid Cancer.

Objective: To compare of the histopathological and oncological outcomes of patients undergoing laparoscopic or open resection surgery for sigmoid colon cancer. Methods: All of the patients who underwent surgical resection for sigmoid colon cancer between July 2014 and December 2016 were included in this study. The demographic characteristics, T/N staging, number of benign/malignant lymph nodes, histopathological findings, follow-up period, overall survival, and disease-free survival (DFS) of both groups were evaluated. Results: A total of 43 patients were evaluated in this study. The female to male ratio was 14/29. The mean age of the patients was 64.11±11.75 years. The median number of dissected lymph nodes was 20.9 (10-31) in the open resection group and 19.46 (7-36) in the laparoscopic group (p=0.539). The overall 3-year survival was 87% in the open resection group and 85% in the laparoscopic group (p=0.62). The 3-year DFS rate was 79% in the open surgery group and 75% in the laparoscopic group (p=0.70). Conclusion: Laparoscopic and open surgery for sigmoid colon cancer provide equivalent oncological results; laparoscopic surgery can be performed safely in these patients. When the laparoscopic surgery technique is standardized and efforts are made to improve training, laparoscopic surgery will likely become standard treatment for colon cancer. [ABSTRACT FROM AUTHOR]
