Gastric cancer in the stomach after Roux-en-Y gastric bypass or mini-gastric bypass is rare, but a few cases have been reported since 1991, when the first case emerged. According to the literature, the interval between bypass surgery and the diagnosis of cancer ranged from 1 to 22 years. Given the difficulty of monitoring a bypassed stomach, the potential for gastric cancer must be considered, especially in countries with high incidence of this cancer. The literature reported the first case in the Asia-Pacific region - a woman developed advanced gastric cancer in her stomach 9 years after laparoscopic mini-gastric bypass for morbid obesity.
