Minimally invasive surgery for gastric cancer in Brazil: current status and perspectives-a report from the Brazilian Laparoscopic Oncologic Gastrectomy Group (BLOGG).

The minimally invasive surgery for gastric cancer in Brazil has begun about two years after the first laparoscopic gastrectomy (LG) performed by Kitano in Japan, in 1991. Although the report of first surgeries shows the year of 1993, there was no dissemination of the technique until the years 2010. At that time with the improvement of optical devices, laparoscopic instruments and with the publications coming from Asia, several Brazilian surgeons felt encouraged to go to Korea and Japan to learn the standardization of the LG.
