<i>Background and Objectives:</i> There is general agreement on the benefits of laparoscopy for treatment of rectal and left colon cancers, whereas findings regarding the comparison of laparoscopic and open right colonic resections are discordant. The aim of this systematic review and meta-analysis was to assess the outcomes and advantages of laparoscopic versus transverse-incision open surgery for management of right colon cancer. <i>Materials and Methods:</i> A systematic review was performed according to the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines. Comparative studies evaluating the results of laparoscopic and transverse-incision open right hemicolectomies were analyzed. The measured outcomes were mean operative time, time to feeding, duration of hospital stay, and number of lymph nodes harvested. <i>Results:</i> A total of 5 studies including 318 patients met the inclusion criteria. Meta-analysis revealed no differences in time to resume oral feeding, hospital stay, and number of lymph nodes harvested in between groups, but mean length of surgery was significantly longer in the laparoscopic group. <i>Conclusion:</i> These data confirm that the preferred approach to right hemicolectomy is yet unclear. Laparoscopy has a longer operative time than transverse-incision open surgery, and no significant short-term benefits were observed for the studied parameters. Well-designed randomized control trials (RCTs) might help to identify the differences between these two techniques for the surgical treatment of right colon cancer.
