    "abstract": "This is an updated meta-analysis comparing the postoperative complications observed with robotic versus laparoscopic surgery (LS) for the treatment of rectal cancer.\nCochrane central, MEDLNE (Medical Literature Analysis and Retrieval System Online), EMBASE (Excerpta Medica dataBASE), Google Scholar, Web of Science and http://www.ClinicalTrials.gov were searched for studies (published after the year 2015), comparing robotic versus LS for the treatment of rectal cancer. The postoperative outcomes were considered as the endpoints in this analysis. RevMan 5.4 was used to carry out the statistical analysis. Risk ratio (RR) with 95% confidence intervals (CI) were used to represent the results following data analysis.\nA total number of 22,744 participants were included in this study whereby 9178 participants were assigned to the robotic surgery and 13,566 participants were assigned to the LS group. The time period of patients' enrollment varied from years 2007 to 2017. Our results showed that overall complications (RR: 0.91, 95% CI: 0.71-1.17; P\u200a=\u200a.45), wound complications (RR: 0.81, 95% CI: 0.64-1.04; P\u200a=\u200a.09), anastomotic leak (RR: 1.12, 95% CI: 0.88-1.42; P\u200a=\u200a.37), anastomotic bleeding (RR: 0.88, 95% CI: 0.29-2.64; P\u200a=\u200a.82), stoma-related complications (RR: 0.88, 95% CI: 0.24-3.21; P\u200a=\u200a.85), intra-abdominal abscess (RR: 0.53. 95% CI: 0.22-1.31; P\u200a=\u200a.17), urinary tract infection (RR: 0.94, 95% CI: 0.53-1.66; P\u200a=\u200a.83), enterocolitis (RR: 1.35, 95% CI: 0.38-4.71; P\u200a=\u200a.64), reoperation (RR: 0.85, 95% CI: 0.46-1.54; P\u200a=\u200a.58), and mortality (RR: 0.75, 95% CI: 0.34-1.62; P\u200a=\u200a.46) were not significantly different between robotic-assisted versus LS for rectal cancer. Postoperative ileus (RR: 1.21, 95% CI: 0.81-1.81; P\u200a=\u200a.34), readmission (RR: 1.17, 95% CI: 0.75-1.83; P\u200a=\u200a.48), and urinary retention (RR: 0.51, 95% CI: 0.21-1.23; P\u200a=\u200a.14) were also similarly manifested.\nIn this updated meta-analysis, both robotic and laparoscopic surgeries were equally effective for the treatment of rectal cancer. Similar postoperative complications were observed. However, our analysis was restricted only to postoperative outcomes, parameters such as duration of surgery were not taken into consideration.",
