%X <B>BACKGROUND: </B>A meta-analysis was conducted on the perioperative and oncological outcomes of robot-assisted and laparoscopic lateral lymph node dissection in rectal cancer. There are few articles and reports on this topic, and a lack of high-quality research results in unreliable research conclusions. This study includes prospective and retrospective studies to obtain more reliable findings.<BR><B>METHODS: </B>Databases were searched, including PubMed, EMBASE, Cochrane, and Web of Science. The search was conducted from the time of database construction to March 2024. The quality of the literature was evaluated using the NOS scoring system. Meta-analysis was performed using R language software. Statistical heterogeneity was assessed using the I2 statistic, and sensitivity analysis was performed.<BR><B>RESULTS: </B>Six relevant literatures that met the criteria were finally included, and 652 patients were included, including 316 (48.5%) in the robot-assisted lateral lymph node dissection for rectal cancer group (RLLND) and 336 (51.5%) in the laparoscopic lateral lymph node dissection for rectal cancer group (LLLND). Analysis of the results showed that compared with the laparoscopic group, the robotic group had less mean intraoperative blood loss (MD = - 22, 95% CI - 40.03 to - 3.97, P < 0.05), longer operative time (MD = 51.57, 95%CI 7.69 to 95.45, P < 0.05), and a shorter mean hospital stay (MD = - 1.25, 95%CI - 2.46 to - 0.05, P < 0.05), a low rate of urinary complications (OR 0.39, 95%CI 0.23 to 0.64, P < 0.01), a low overall rate of postoperative complications (OR 0.6, 95%CI 0.42 to 0.87, P < 0.01), and a high number of lateral lymph node dissection (MD = 1.18, 95% CI 0.14 to 2.23, P < 0.05), and there was no statistically significant difference between the two groups in terms of postoperative anastomotic leakage, postoperative intestinal obstruction, and total number of lymph nodes obtained (P > 0.05).<BR><B>CONCLUSIONS: </B>Compared with laparoscopy, robotic lateral lymph node dissection for rectal cancer reduces intraoperative blood loss, shortens the average length of hospital stay, reduces urologic complications, decreases overall postoperative complications, and collects more lateral lymph nodes. However, the surgical time is prolonged.
