456 Comparison of Postoperative Outcomes Between Robotic and Laparoscopic Surgery for Inflammatory Bowel Disease: A Systematic Review and Meta-Analysis

To evaluate comparative outcomes of robotic versus laparoscopic bowel resection in patients with inflammatory bowel disease (IBD). A systematic online search was conducted using the following databases: PubMed, Scopus, Cochrane database, The Virtual Health Library, Clinical trials.gov and Science Direct. Comparative studies comparing robotic versus laparoscopic resection for IBD were included. Primary outcomes were post-operative complications rate. Operative time, conversion to open, length of hospital stays, and mortality were the evaluated outcome parameters. Eleven studies with total number of 5,566 patients divided between those undergoing robotic (n=365) and conventional laparoscopic (n=5,201) surgery. Moreover, subgroup analysis for sub-total colectomy group showed shorter LOS [MD: -1.62, P=0.03]. Overall complications rate was significantly higher in the laparoscopy group compared to robotic group [OR: 0.48, P=0.03], however the operative time was longer in the robotic group [MD: 40.61, P=0.00001]. Pooled analysis showed comparable results regarding conversion to open [OR: 0.46, P=0.15], anastomosis leak [OR: 0.92, P=0.84], abdominal abscess / collection [OR: 0.34, P=0.21], and mortality [RD: 0.00, P=1.00]. Compared to laparoscopic approach, Robotic surgery provides a significantly lower rate of post-operative complications and shorter LOS at the expense of operative time with similar 30-day Mortality.
