Background:
The study aimed to compare the clinical outcomes of robotic right colectomy (RRC) versus laparoscopic right colectomy (LRC) in patients diagnosed with right colon cancer, given the increasing adoption of robotic surgical techniques and their potential benefits in oncologic surgery.
Methods:
This retrospective comparative study included patients who underwent right colectomy at Sir Run Run Shaw Hospital, College of Medicine, Zhejiang University, between January 2019 and May 2022. The primary outcomes measured were the number of lymph nodes harvested. Key secondary outcomes included the operation time, intraoperative blood loss, postoperative complications, hospitalization costs, overall survival (OS), and disease-free survival (DFS). Data were analyzed using multivariable Cox proportional hazards regression to adjust for potential confounders.
Results:
A total of 225 patients (aged 65.23 ± 11.45, 108 males) with right colon cancer were included, with 100 (44.4%) patients underwent RRC. Patients who underwent RRC had significantly more lymph nodes harvested (27.69 ± 12.59 vs. 24.43 ± 9.42, P = 0.028), and incurred higher total hospitalization costs compared to those with LRC (9.68 ± 7.12 vs. 5.28 ± 1.23 ten-thousand-yuan, P < 0.001). The OS and DFS were comparable between RRC and LRC (both P > 0.05) within a median follow-up of 27 (range, 9-44) months. Multivariable cox proportional hazards regression showed that patients underwent RRC had significantly higher risk for all-cause death compared with those underwent LRC [hazards ratio (HR) = 2.303, 95% confidence intervals (CI): 1.625-3.265, P < 0.001].
Conclusion:
Patients underwent RRC seemed to have significantly more numbers of lymph nodes harvested and higher risk for all-cause death and higher hospitalization costs compared with those underwent LRC. These findings suggest a need for careful consideration of the benefits and risks associated with robotic versus laparoscopic right colectomy in clinical practice.
