Laparoscopic intragastric surgery for treating early gastric cancer

BACKGROUND/AIM: Although there is an increasing number of studies on laparoscopic resection of early gastric cancer (EGC), as of 2018 no standardized strategy exists. We reviewed available literature dealing with laparoscopic intragastric (intraluminal) surgery (LIGS) conducted for patients with EGC to better define indications, benefits and limitations of this particular minimally invasive technique. MATERIALS AND METHODS: PubMed, MEDLINE, Science Direct, Scopus, Web of Science, Google Scholar and ResearchGate were the search engines investigated. Only LIGS for EGC was entertained; studies conducted for other gastric diseases were excluded. Suitable articles written in all languages were included in the review. RESULTS: As of 2018, we found 19 studies dealing with LIGS for EGC: studies on 72 humans and four pigs were identified. Among 72 human participants, there were 59 mucosal, five submucosal and one subserosal cancer. CONCLUSION: Based on our review, LIGS appears as a cogent option to endoscopic resection for treating superficial EGC
