The aim of this study is to review the literature and report the various minimally invasive methods used to treat gastric cancer in the UK and compare it with worldwide practice. Published randomised studies, non-randomised studies and case series reporting the use of minimal invasive approach to treat gastric cancer were retrieved from the search of standard medical electronic databases and their outcomes were highlighted suggesting their effectiveness. Several randomised, controlled trials and meta-analyses have proven the clinical and oncological safety of the laparoscopic gastrectomy for gastric cancer. Similarly, robot-assisted gastrectomy, EMR (endoscopic mucosal resection) and ESD (endoscopic sub-mucosal dissection) have also been proven feasible and safe to treat gastric cancer of various stages in prospective and retrospective comparative studies. However, UK based studies on minimally invasive surgery to treat gastric cancer is scarce and the paucity of trials led to uncertain outcomes. Laparoscopic gastrectomy, robot-assisted gastrectomy, EMR and ESD are feasible procedures in terms of clinical and oncological safety but mainly being practiced in Asian countries with high prevalence of stomach cancer. The UK based practice is still small and limited but the introduction of MIGOCS and STOMACH trial might help to widen the application of this technique.
