Operative and long-term oncological outcomes in patients undergoing robotic versus laparoscopic surgery for rectal cancer.

ABSTRACT

BACKGROUND: This study aimed to compare short- and long-term outcomes after robotic versus laparoscopic approach in patients undergoing curative surgery for rectal cancer. METHODS: Patients undergoing elective robotic and laparoscopic resection for rectal cancer were included. Perioperative clinical characteristics, postoperative short- and long-term outcomes were compared between groups. RESULTS: There were 72 and 44 patients in robotic (RG) and laparoscopic (LG) groups respectively. No differences were detected regarding patients' demographics, histopathologic outcomes, conversion rates and 30-day overall postoperative complication rates. Operative time was longer in the RG (341 ± 111.7 vs. 263 ± 97.5 min, p = 0.001) and length of stay was longer in the LG (4.4 ± 1.9 vs. 6.4 ± 2.9 days, p = 0.001). The 5-year overall and disease-free survival rates were similar (97.1% and 94.9%, p = 0.78; 86.2% and 82.7%, p = 0.72) between the groups. CONCLUSION: This study showed both short and long-term outcomes of a limited number of included patients between the robotic and laparoscopic surgery were similar. However, future studies and randomized trials are necessary to establish these findings.
