SP5.5 Peri-operative, Oncological and Functional Outcomes of Robotic versus Transanal Total Mesorectal Excision in patients with Rectal Cancer: A Systematic Review and Meta-analysis

Abstract Background To evaluate comparative outcomes of robotic low anterior resection (RTME) and spinal Trans-anal total mesorectal excision (TaTME) in patients with rectal cancer. Methods A systematic online search was conducted using the following databases: PubMed, Scopus, Cochrane database, The Virtual Health Library, Clinical trials.gov Science Direct. Comparative studies comparing RTME versus TaTME for cancer were included. Primary post-operative complications namely, anastomosis leak, SSI, overall rate, Clavien-Dindo rate. Operative time, conversion to open, Intra-operative blood loss, ITU hospital length stay (LOS), complications, oncological outcomes, functional evaluated outcome parameters. Results Twelve a number 3025 divided between Robotic group (n=1881) (n=1144) There significant difference two groups regarding time (P=0.39), open (P=0.29) intra-operative loss (P= 0.62). ≥ 3 rate (P=0.25), leak 0.89), re-operation (P=0.62), re-admission (P=0.92), R0 0.52), LOS 0.63) (P=0.30) showed similar results groups. higher harvested lymph nodes 0.04) completed TME (P=0.05). Wexner LARS scores significantly better compared 0.0009) 0.00001), respectively. Conclusion Compared TaTME, provides complete postoperative
