Comparison of Short-Term Results of Laparoscopic and Open Surgeries for Colorectal Cancer: A Single-Center Experience

Objective: Although laparoscopic colon cancer surgeries have increased in recent years, their oncological competence is questioned. In our study, we aimed to evaluate oncological competence by comparing laparoscopic and open surgery. Method: The study was planned retrospectively. A total of 94 patients were included in the study, 42 of whom underwent laparoscopy, and 52 patients underwent open surgery. Both groups were compared in terms of demographic characteristics, staging, number of benign/malignant lymph nodes, histological findings, and complications. Result: The final pathology report of all patients was adenocarcinoma. The median number of dissected lymph nodes was 20.9 in the open group (8-34) and 19.46 in the laparoscopy group (7-31) (p = 0.639). The median number of dissected malignant lymph nodes was 1 (0-13) in the open surgery group and 3.1 (0-8) in the laparoscopy group (p = 0.216). The laparoscopy group exhibited a longer operation time (281.2 +/- 54.2 and 221.0 +/- 51.5 min, respectively; p = 0.036) than the open surgery group, but a shorter intensive care unit (ICU) discharge, quicker initiation oral feeding, and shorter length of hospital stay (4.0 +/- 0.9 vs 5.7 +/- 2.0 days, respectively; p < 0.001). Discussion: Laparoscopic surgery elicits many benefits such as less wound infection, lower requirement for blood transfusion, shorter hospitalization, quicker initiation of oral feeding, and mobilization. Our study has shown that laparoscopic surgery provides quite adequate lymph node dissection when compared to oncological surgery, which is viewed with suspicion in the light of these benefits of laparoscopy.
