Cancer of gastric remnant

Cancer of gastric remnant (gastric stump cancer), also known as gastric cancer after gastric surgery. Because it can occur in the residual stomach after gastrectomy, can also occur in the entire stomach with a simple perforation repair or after vagotomy. Is generally believed that the stomach should be limited to non-cancer lesions of gastric cancer after surgery, if surgery for malignant lesions and those who should refer to more than 20 years after surgery of gastric cancer occurred.

Gastric remnant gastric cancer accounted for 0.4% ~ 5.5%. Incidence of 1% ~ 5%. Male to female ratio was 5.4:1, with an average age of onset is 65 years. Residue from the stomach of gastric cancer surgery to the average interval of 13 to 19 years, the longest interval of 40 years, a small number of cases less than 10 years. Is generally believed that 15 years after gastric surgery, the incidence of gastric stump cancer than the general population of gastric cancer is lower, and after more than 15 years, the incidence gradually increased to more than 20 years after, its incidence is higher than the general population 6 ~ 7 times.

Stomach and duodenum after surgical resection of the incidence of gastric stump cancer generally similar between the two. The incidence of gastric stump cancer surgery and the way the first time. After subtotal resection for Pichia and simple Ⅱ gastrojejunostomy than patients who Pichia Ⅰ-type residues more susceptible to gastric cancer. Remnant gastric cancer is a good anastomotic site, but can also occur in diffuse gastric whole.
